WIRING CONNECTIONS
The electrical connections are made via rear screw-clamp terminals
located on the back of the unit. All conductors should meet voltage and
current ratings for each terminal. Also cabling should conform to
appropriate standards of good installation, local codes and regulations. It is
recommended that power supplied to the unit (AC or DC) be protected by a
fuse or circuit breaker. When wiring the unit, use the label to identify the
wire position with the proper function. Strip the wire, leaving
approximately 1/4" bare wire exposed (stranded wires should be tinned with
solder). Insert the wire into the screw-clamp terminal and tighten the screw
until the wire is clamped tightly. Each terminal can accept up to two #14
AWG wires.
The backlighting for a backlight version unit is powered between
Terminal 2 (V+) and Terminal 1 (GND).
Refer to the EMC Installation Guidelines section of this bulletin for
additional information.

EMC INSTALLATION GUIDELINES
Although this unit is designed with a high degree of immunity to
ElectroMagnetic Interference (EMI), proper installation and wiring methods
must be followed to ensure compatibility in each application. The type of the
electrical noise, source or coupling method into the unit may be different for
various installations. In extremely high EMI environments, additional measures
may be needed. Cable length, routing and shield termination are very important
and can mean the difference between a successful or a troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in
order of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the unit and leave the other end of the
shield unconnected and insulated from earth ground.
2. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
3. Signal or Control cables within an enclosure should be routed as far away as
possible from contactors, control relays, transformers, and other noisy
components.
4. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional protection.
Install line filters on the power input cable to the unit to suppress power line
interference. Install them near the power entry point of the enclosure. The
following EMI suppression devices (or equivalent) are recommended:
Variable Frequency AC Inputs, Signal Source Powered
Variable Frequency AC Inputs, Signal Source Powered
Minimum VAC for operation is 0.9 V peak.

REAR PANEL DIP SWITCHES
The Timebase increment total is computed according to the following formula:
When viewing the Ditak 8 from the rear, there are two banks of DIP switches
located along the top edge of the PC board. The bank of eight switches to the left
is labeled SWA and the bank of six switches to the right is labeled SWB. All of
the SWA switches and five of the SWB switches are used to select the desired
Timebase. The remaining switch of SWB is used to select Frequency Doubling.

TBIT = 614.44
FREQUENCY DOUBLING
DIP switch SWB 6 is the “Frequency Doubling” switch. When it is in the
“ON” position, frequency doubling is disabled. When set to the “OFF” position,
it is enabled and twice the number of input pulses are registered in the unit. This
doubling of the input rate allows the Timebase Increment Total to be halved,
thus allowing a faster update time for a given display value.
TBIT = 614 {round to the nearest whole number}
TBIT = 614
TIMEBASE SELECTION
The Ditak 8 has a Timebase selection range from 3.906 msec to 31.998 sec.
SWA 1 is set to the “ON” position for the minimum Timebase setting. SWA 1
through SWB 5 are set to the “ON” position for the maximum Timebase setting.
A specific Timebase setting is achieved by adding the appropriate individual
Timebase increments.

TYPICAL APPLICATION
CONVEYOR BELT SPEED INDICATOR
It is desired to display the rate of a conveyor belt used to carry PC Boards through an infrared soldering chamber that is variable from 0 to 10 feet per minute.
The rate must be adjusted depending on the size of the boards being soldered. The display of the rate indicator must read in feet per minute. The shaft of the variable
speed motor contains a keyway. A speed of 100 RPM will produce a belt speed of 10 ft/min. A proximity sensor is used to monitor the speed of the shaft. The Ditak
8 can be used to display the belt speed in this application. The output signal of the sensor is connected to the Ditak 8 Terminal 3 (INP). The sensor common and
shield are connected to the Ditak 8 Terminal 1 (GND). The Timebase setting is to be determined by using the formula.
TIMEBASE INCREMENT TOTAL (TBIT) =
DR x 15,361

With these DIP switch settings, the Timebase would be approximately 5.99 sec
(1536 x 0.003906 = 5.995). To reduce the display update time, the “Frequency
Doubling” switch can be enabled (set to the “OFF” position). Therefore, only half
the Timebase will be necessary (768 x 0.003906 = 2.99 sec.).

INSTALLATION ENVIRONMENT
The unit should be installed in a location that does not exceed the maximum
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
INSTALLATION
The Ditak 9 meets NEMA 4X/IP65 requirements for indoor use, when
properly installed. The units are intended to be mounted into an enclosed
panel. A sponge rubber gasket, mounting clip, two screws, and nut fasteners
are provided to install and seal the unit in the panel cut-out.
The following procedure assures proper installation:
1. Cut panel opening to specified dimensions. Remove burrs and clean panel
opening.
2. Slide the panel gasket over the rear of the unit to the back of the bezel.
3. Slide nut fastener into slot on mounting clip and then insert mounting screw
through nut on both sides of mounting clip. Tip of mounting screw should
NOT project through hole on clip.
4. Install Ditak unit through panel cut-out.
5. Slide mounting clip over rear of unit until clip is against back of panel. The
mounting clip and Ditak housing have a latching feature to hold the unit in
place until tightened.
Note: Hold the Ditak front bezel in place when sliding the mounting clip
into position.
6. Alternately tighten each mounting screw to ensure uniform gasket pressure.
Visually inspect the gasket for proper seal. The gasket should be
compressed approximately 75 to 80% of its original thickness.
7. If the gasket is not adequately compressed and the mounting screws cannot
be tightened any further, loosen mounting screws and insure that the clip is
latched as close as possible to the panel.
8. Repeat step #6 for tightening the mounting screws.
PROGRAMMING MENU
RATE MULTIPLIER
The Ditak 9 has a Rate Multiplier (RM) selection range from 0.0001 to
1.9999. See Programming Calculations to determine the calculated value. After
entering the programming mode, the least significant digit will be flashing. To
increment this digit, press the SEL button. After the value 9, the digit will start
over at 0. To move to the next digit press PAR and then that digit can be changed
by pressing SEL. When reaching the most significant digit, pressing PAR will
advance the meter to the Decimal Point selection.
DECIMAL POINT SELECTION
The selection of the decimal point position for the display (DDP) is
accomplished by repeatedly pressing SEL. This selection will always default to
0.0000 when advancing to it from the Rate Multiplier selection. By pressing
PAR, the shown decimal point selection is entered and the Time base selection
is shown.
Note: The display changes on “PAR” or “SEL” push button release.
PROGRAMMING
TIMEBASE SELECTION
From the factory, the Ditak 9 is programmed with a fixed 1 second timebase
to read directly in HZ or RPM with a 60 tooth gear To enter the programming
mode, place a jumper between the Push Button Enable (P. B. En.) Terminal and
the Common Terminal. Once the jumper is connected the programming buttons
are now activated. The Programming Mode consists of three selections; Rate
Multiplier, Decimal Point, and Timebase. There is a fourth display which is the
main display or run mode. Once programming is complete, the unit must be
returned to the main display before exiting the programming mode to obtain
normal operation.
The Ditak 9 has a Time Base selection range from 1 second to 7 seconds. See
Programming Calculations to determine the calculated Rounded Time Base
(RTB) value. The value is changed by pressing SEL. The value is entered by
pressing PAR and the Main Display/Run Mode is shown.
Note: The position of the decimal point has no effect on this selection.
MAIN DISPLAY/RUN MODE
This display follows the Timebase Selection. The unit must be in this mode to
exit the Programming Mode and have the unit display properly. The push button
enable jumper can be removed after the Ditak 9 is returned to the main display.

USING KNOWN PULSES PER UNIT
An amusement park director wants his parking tram operators to keep their
speed under a certain limit. He has a magnetic sensor looking at a shaft on the
tram with 30 pulses per revolution. When the shaft is turning at 50 RPM he
wants the meter to show 15.5. The Ditak 9 is programmed as follows:
A newspaper company wants to know the line speed of their press to tenths
of feet per minute. They have an encoder that gives 125 pulses per foot. The

DESCRIPTION
The Gemini 5200 is a multifunction Dual Rate Indicator which can fulfill
almost any rate indication application. The unit can operate as two independent
rate indicators, with scaling, decimal point placement, and update times
separately programmable for each channel. The Gemini 5200 also has three
other unit personalities. These personalities feature a third display Channel C,
which can indicate the ratio, difference or draw between the A and B rate
channels.
The programming of the rate channels and the calculated display is a very
straightforward task. Setting up Channel C only requires programming the
desired amount of resolution (for ratio and draw) and the appropriate decimal
point location. The Gemini 5200 simply takes the two rate values and
mathematically calculates display “C” accordingly.
The rate indicators use a time interval method (1/tau) to calculate the rate
value. This method enables high resolution at all input rates. The unit counts
input pulses and after a programmable minimum update time has occurred, it
waits until the next count edge occurs, then takes the elapsed time and number
of edges and calculates the rate value. At slower rates, averaging can be
accomplished by programming the “Rate Minimum Update Time” (0.5 sec. to
16 sec.) for the desired response. The minimum input frequency is 0.03
counts/sec. or one pulse every 32 sec. Extensive scaling capabilities allow
practically any desired reading at very slow input rates.
The 20mA Current Loop Communications Option provides the capability of
two-way serial communications between the Gemini and other equipment such
as a printer, programmable controller, or host computer. The baud rate can be
set to 300, 600, 1200, or 2400 baud. The format for transmitted and received
data is 1 start bit, 7 data bits, 1 parity bit (odd), and a stop bit. When utilizing
an external power supply (30 VDC max.), up to sixteen units can be installed in
the loop, each with an individual address. When utilizing the Gemini’s 20 mA
current source, up to seven units can be installed in a loop. The Rate values,
Presets, and Scale Factors can all be interrogated, while the Presets and Scale
Factors can also be changed by sending the proper command codes and

PROGRAMMING
GEMINI 5200 APPLICATIONS
The Gemini 5200 input circuit set-up is programmed using DIP switches on
the rear of the unit. All other functions are programmed through the front panel
pushbuttons.
To program or interrogate a function, the user first enters a two-digit function
code. The unit will then display that function code along with a single-digit
mode identifier.
EXAMPLE: The function code representing “Output 1 Termination Modes” is
52. The mode identifiers for this function are:
3. Terminate at Manual Reset
4. Terminate at Manual Reset End
5. Terminate after Timed Output 1
6. Boundary
To interrogate the output termination mode, Press “5”,
then “2”:
Unit displays the function code along with mode
identifier 3 (Terminate at Manual Reset).
To change this mode to “Terminate After Timed
Output”, Press “5”:
To enter and save the new mode, Press “E”:
Unit enters new mode and returns display to the present
selected display value.
The most commonly used functions, Presets and Scale Factors, are initialized
through single front panel pushbuttons rather than a two-digit function code.
Pressing the “P” or “SF” pushbuttons will immediately display the current
Preset or Scale Factor value for the selected display. To change any digit, the
user presses the pushbutton directly below that particular digit, which is then
scrolled until the desired value is obtained. Each digit is changed, if necessary,
in the same manner until the complete Preset or Scale Factor value is registered
on the display. Pressing the “E” pushbutton completes the entry sequence.
MONITORING TWO SEPARATE RATES IN ONE
PROCESS
Many applications require more than one rate to be monitored for a given
process. The Gemini 5200 allows the monitoring of two independent rates
with one instrument and provides separate scaling for each channel when
required.
In this example, an industrial saw blade is used to cut timbers to length.
The application requires monitoring both saw blade speed in RPM and feed
rate in tenths of inches per minute. The blade is moved into the material
with a lead screw which makes 12 revolutions per inch of travel. The lead
screw is driven by a 1750 RPM motor through a 2:1 gear reducer which
yields a speed of 875 RPM. Since the blade moves 1 inch in 12 revolutions,
the feed rate of the blade will be 72.9 inches per minute. (875 RPM/12
revolutions per in. = 72.9 in./min.)
A Model LMPC sensor is used to sense a raised target on the lead screw
which delivers 1 pulse per revolution to Rate Channel A of the Gemini
5200. In terms of travel, one pulse represents 0.0833” (1/12”). However,
since the desired readout is in tenth inches, the input must be multiplied by
10. Therefore, a scale factor of 0.8333 is programmed into Channel A. A
decimal point is programmed to the left of digit 1 and the Rate A conversion
factor is programmed for Rate per Minute (x60) which automatically
multiplies the input pulses by 60 to yield a direct readout in inches per
minute.
Measuring saw blade speed is a simple matter of using an LMPC sensor
to detect a keyway in the blade drive shaft which delivers one pulse per
shaft revolution to Channel B of the Gemini 5200. Programming the Rate
B scaler for rate per minute (x60) yields a direct reading of blade speed in
RPM.
To interrogate the Preset value, Press “P”:
Unit displays current Preset value.
To change the Preset value:
Any digit may be changed by pressing the pushbutton
directly below it. Release the pushbutton when the digit
reaches the desired value.
Press “E”:
Unit enters new Preset value and returns display to the
present selected display value.
The Gemini 5200 Series can display any of three
selected display values as indicated by LED’s along the
left side of the display.
To display a different value:
Press the “DISP” pushbutton repeatedly until the
indicator corresponding to the desired value turns on.

GEMINI 5200 APPLICATIONIS (Cont’d)
CONTROLLING THE RELATIONSHIP BETWEEN SPECIFIED AMOUNTS OF MATERIAL
gallons per foot, but rather gallons per 100 feet which requires the display to
be multiplied by another factor of 100. Therefore, the Channel C scale
multiplier is programmed for x10,000 (i.e. 100 x 100) which provides the
desired Channel C reading of gallons per 100 feet to the nearest hundredth
gallon.
The relay outputs of the Gemini 5200 are connected to a speed control
mechanism on the glue pump which increases or decreases the glue flow rate
while the appropriate relay contacts are closed. Both preset outputs are
assigned to Channel C in the boundary mode of operation and are
programmed for the upper and lower acceptable limits of the glue flow rate.
In this case, the pump initially increases the output flow until a rate of 2.00
gallons per 100 feet is reached, at which time Output 1 toggles to prevent
further increase in speed.
If the flow rate reaches or exceeds 2.50 gallons per 100 feet, Output 2 will
toggle and send a correction signal to the pump until the speed slows to
acceptable limits. If the rate falls back below the lower limit, Output 1 again
toggles to speed-up the glue pump.
The Gemini 5200 can be used in this type of application to indicate and
control virtually any process that requires the distribution of a specified
amount of material in relation to another specified amount of material.
This application involves the monitoring and control of a glue allocation
process on a continuous web of industrial grade paper. In this case, the desired
results are to maintain a flow of glue between 2.00 and 2.50 gallons per 100
feet of web. To accomplish this, a Gemini 5200 is used in the A/B ratio
indicator mode, which will yield a direct readout in gallons per 100 feet to the
nearest hundredth gallon.
Channel A is connected to a 100 PPR RPGC pulse generator which is
mounted to the shaft of the glue pump. The pump delivers 0.38 gallons per
shaft revolution. Therefore, a scale factor of 0.3800 is programmed into
Channel A of the Gemini 5200 to yield 38 pulses per revolution. This
effectively multiplies the glue flow rate by 100 which allows a decimal point
to be programmed to the left of digit 2, producing a display of gallons per
second to the nearest hundredth gallon on Channel A.
A length sensor providing one pulse per foot of web material is fed into
Channel B of the Gemini. The Channel B scale multiplier is programmed for
x100 to produce a display reading of feet per second to the nearest hundredth
on Channel B.
The Gemini 5200 performs the A/B calculation and displays the ratio in
gallons per feet on Channel C. Since the application requires resolution in
hundredths of gallons, the Channel C display must be multiplied by 100 to
provide such resolution. However, the desired readout is not in terms of

GENERAL DESCRIPTION
SAFETY SUMMARY
The PAX Lite Rate Meter, Model PAXLR, provides the versatility and
flexibility needed to accommodate virtually any rate measuring application. The
meter has the ability to scale for direct readout in terms of the units being
measured. Whether a machine produces bottles, cloth, wire, or beverage mix,
operation is enhanced when the rate readout is expressed directly in bottles/min.,
feet/min., gallons/min., or whatever units are needed in plant applications.
The PAXLR can accommodate magnetic pickups, logic sensors, and NPN
open collector sensors. The pulses are received and scaled, so the desired
display can be achieved. The meter is programmed through both the front panel
buttons and DIP switches. Once the programming is complete, the front panel
buttons can be disabled by a DIP switch setting.
The meter has been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing to meet CE
requirements, the meter provides a tough, yet reliable application solution.
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
DIMENSIONS In inches (mm)
CAUTION: Read complete
instructions prior to installation
and operation of the unit.
CAUTION: Risk of electric shock.
Note: Recommended minimum clearance (behind the panel) for mounting clip installation is
2.1" (53.4) H x 5" (127) W.

c. Connect the shield to common of the meter and leave the other end of the
shield unconnected and insulated from earth ground.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be ran in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
4. Signal or Control cables within an enclosure should be routed as far as possible
from contactors, control relays, transformers, and other noisy components.
5. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional protection.
Install line filters on the power input cable to the unit to suppress power line
interference. Install them near the power entry point of the enclosure. The
following EMI suppression devices (or equivalent) are recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC# FCOR0000)
TDK # ZCAT3035-1330A
Steward # 28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC# LFIL0000)
Schaffner # FN670-1.8/07
Corcom # 1 VR3
Note: Reference manufacturer’s instructions when installing a line filter.
6. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
7. Switching of inductive loads produces high EMI. Use of snubbers across
inductive loads suppresses EMI.
Snubber: RLC# SNUB0000.
WIRING OVERVIEW
Electrical connections are made via screw-clamp terminals located on the
back of the meter. All conductors should conform to the meter’s voltage and
current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that the power
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.
When wiring the meter, compare the numbers embossed on the back of the
meter case against those shown in wiring drawings for proper wire position. Strip
the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded wires
should be tinned with solder.) Insert the lead under the correct screw-clamp
terminal and tighten until the wire is secure. (Pull wire to verify tightness.)
EMC INSTALLATION GUIDELINES
Although this meter is designed with a high degree of immunity to ElectroMagnetic Interference (EMI), proper installation and wiring methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, source or coupling method into the meter may be different for various
installations. The meter becomes more immune to EMI with fewer I/O
connections. Cable length, routing, and shield termination are very important
and can mean the difference between a successful or troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. The meter should be mounted in a metal enclosure, which is properly
connected to protective earth.
2. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in order
of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.

METER
RATE SCALING
NOTES:
1. If # of pulses per unit is less than 10, then multiply both Input and Display
values by 10.
2. If # of pulses per unit is less than 1, then multiply both Input and Display
values by 100.
3. If the Display value is raised or lowered, then Input value must be raised
or lowered by the same proportion (i.e. Display value for per hour is
entered by a third less (1200) then Input value is a third less of # of pulses
per unit). The same is true if the Input value is raised or lowered, then
Display value must be raised or lowered by the same proportion.
4. Both values must be greater than 0.0.
To scale the Rate, enter a Scaling Display value with a corresponding Scaling
Input value. These values are internally plotted to a Display value of 0 and Input
value of 0 Hz. A linear relationship is formed between these points to yield a
rate display value that corresponds to the incoming input signal rate. The
location of the scaling point should be near the process end limit for the best
possible accuracy. The PAXLR is capable of showing a rate display value for
any linear process.
SCALING CALCULATION
If a display value versus input signal (in pulses per second) is known, then
those values can be entered into Scaling Display (!"#$%&) and Scaling Input
(!"#'(&). No further calculations are needed.
If only the number of pulses per ‘single’ unit (i.e. # of pulses per foot) is
known, then it can be entered as the Scaling Input value and the Scaling Display
value will be entered as the following:
EXAMPLE:
1. With 15.1 pulses per foot, show feet per minute in tenths.
Scaling Display = 60.0 Scaling Input = 15.1
2. With 0.25 pulses per gallon, show whole gallons per hour. (To have greater
accuracy, multiply both Input and Display values by 10.)
Scaling Display = 36000 Scaling Input = 2.5

The rate of the input signal along with the programmed scaling values can
cause the calculated rate display to exceed the meter’s 6-digit capacity. If this
occurs, the display will show “!"!"!"” to indicate an overflow condition.
INPUT FREQUENCY CALCULATION
The meter determines the input frequency by summing the number of falling
edges received during a sample period of time. The sample period begins on the
first falling edge. At this falling edge, the meter starts accumulating time
towards Low Update and High Update values. Also, the meter starts
accumulating the number of falling edges. When the time reaches the Low
Update Time value, the meter looks for one more falling edge to end the sample
period. If a falling edge occurs (before the High Update Time value is reached),
the Rate display will update to the new value and the next sample period will
start on the same edge. If the High Update Time value is reached (without
receiving a falling edge after reaching Low Update Time), then the sample
period will end but the Rate display will be forced to zero. The High Update
Time value must be greater than the Low Update Time value. Both values must
be greater than 0.0. The input frequency calculated during the sample period, is
then shown as a Rate value determined by either scaling method.

The Apollo Time Interval Rate Indicator (Model APLRI) and Module
(Model PBLRI), provide the capability of measuring very slow input rates and
scaling these low rates in terms of a readily usable and recognizable engineering
unit (i.e. bottles/min., rolls/hr., cases/shift, barrels/day, etc.). The
APLRI/PBLRI measures the time (with crystal controlled accuracy) between
input pulses, inverting this measured time, then multiplying it by the
programmed scale multipliers set by the rear panel DIP switches.
The units can also accommodate magnetic pickups, logic sensors, and NPN
open collector sensors, as well as switch contact closure sensors.
These units have a self-test feature, which checks all the microprocessor and
display driver circuitry after power-up, if enabled. This self-test can also be used
to test the multiplier select DIP switches and decimal point select DIP switches,
to make certain all switches are functioning properly.
Power and input connections are made via a removable terminal block,
located at the rear of the unit. Each terminal can accept one #14 AWG wire. DIP
switches at the side of the unit are used to program the input configuration.
The Model APLRI has a sealed metal die-cast bezel which meets NEMA
4/IP65 specifications for wash-down and/or dust, when properly installed. The
Model APLRI has a 6-digit, 0.56" high LED display, which is readable to 23
feet (7M).

Note: When the input pulse rate is 3 pulses/sec. or lower, the unit will utilize,
if selected, a technique known as a “moving window average”. (This
continually averages the last eight input pulses.)
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
CAUTION: Read complete
instructions prior to installation
and operation of the unit.
CAUTION: Risk of electric shock.

PANEL CUT-OUT

and serves to filter out high frequency noise. It can also be used to filter
switch contact closures.
Note: If excessive contact “bounce” is encountered, an additional external
filter capacitor may be necessary. Reed switches, mercury wetted
contacts, snap action limit switches, and silver alloy relay contacts with
wiping action are usually satisfactory for generating count input signals.
Motor starter contacts, tungsten contacts, and brush-type contacts
should not be used.
S2 - ON [LOGIC]: Sets the bias reference so that input logic signals trigger
count pulses as they cross a level of approximately +2.5 V.
OFF: Sets the bias reference so that a signal of 150 millivolts or more will
trigger count pulses. This provides the sensitivity required for low speed
magnetic pickup sensors.
Note: Hysteresis for both S2 “ON” and “OFF” conditions is about 25
millivolts. This means the difference between VIL and VIH with logic
inputs (S2) is almost insignificant and only a very small swing about the
2.5V bias level will trigger the input.
S3 - ON [NPN O.C.]: Connects a 3.9 KΩ pull-up load resistor for sensors or
circuits with current sink outputs. Sensor output must sink 4 mA @ VOL
of 1 V or less. Unlike the time base rate indicator, the APLRI/PBLRI can
work with switch contact closures because of the low count rate
capability. S1 should be closed when switch contact closures are used as
inputs to the unit.
SPECIFICATIONS (Con’t)
8. MAXIMUM INPUT VOLTAGE AND CURRENT: When the “SIG. IN”
(Terminal 5) is driven from external signal voltages, maximum voltage swing
is ±50 V peak. Input voltage can be dropped by an external series resistance
that limits input current to ±5 mA. (These ratings are for S3 “OFF”.)
9. INPUT IMPEDANCE: With S1 and S3 “OFF”, the resistive input
impedance exceeds 1megohm as long as the “SIG. IN” (Terminal 5) input
voltage is between zero and +12 VDC. Beyond these levels, the high and low
clamping diode will start to conduct, thus decreasing the input impedance.
With S3 “ON” the maximum input voltage to Terminal 5 must be limited to
28 VDC.
10. PARALLELING WITH APOLLO TOTALIZER (RLC standard count
input) INPUTS: Apollo Rate Indicators may be parallel connected with
counters having the RLC standard count input circuitry. These can operate
from a common current sink or source sensor, by connecting the appropriate
terminals in common. S3 on the Rate Indicator should be turned “OFF” since
pull-up or pull-down resistors are already present in the counter. The Rate
Indicator will not add appreciable sensor load with this arrangement.
Note: Rate Indicators cannot be operated in parallel with standard input
counters when 2-wire proximity sensors are used.
11. INPUT AND POWER CONNECTIONS: There is a plug-in,
compression-type, terminal block located at the rear of the unit. This block
can be removed from the rear of the unit for ease of wiring. After wiring is
complete, the connector can be plugged back onto the unit.

MOVING WINDOW AVERAGING & SELF-TEST
DIP switch 6, the S.T./AVG. switch, serves a dual function of disabling or
enabling the “MOVING WINDOW AVERAGE” (MWA) function and the selftest function. When the switch is “UP”, MWA and the self-test are both
disabled. When the switch is “DOWN”, MWA and self-test are both enabled.
MOVING WINDOW AVERAGING
This allows the unit to “collect” and average the last eight input pulses which
is continually updated whenever a new pulse occurs. The oldest input data is
discarded and replaced with the newest data.
SELF-TEST
This unit has a built-in self-test feature which can only be activated
immediately after power-up (the unit will not count while in self-test). To
activate self-test, set the S.T./AVG. DIP switch (D.S. 6) to the enable position.
Then power the unit up. With this test, all digits are cycled through starting with
a string of six zeros. This will be shown for about half a second, then a string
of ones will appear for about the same time duration. Following these, a string
of twos and so on, up to nines will be displayed. After this portion, an interlace
pattern of 1, 0, 1, 0, 1, 0, then 1, 2, 1, 2, 1, 2, and so on, until all digits from zero
to nine have been displayed.
The next portion of self-test will display four groups of zeros and/or ones.
(The first two digits from the left, in each group, will always show a zero.) In
the first group, the third digit represents the 13th (x4096) DIP switch setting.
INPUT SET-UP
The selection of input set-up is accomplished by the first three of six DIP
switches, located along the side of the unit. DIP switches 1-3 are used to
configure the input. Each of these switches are discussed below.
Note: Rate indicators frequently use magnetic pickups for input devices.
Consequently, there are basic differences between counter and rate-indicator
input circuits. In the APLRI/PBLRI input circuit, the hysteresis level is quite
small and the bias levels are significantly different to accommodate both
magnetic pickup inputs, as well as the +5 V and higher logic levels.
S1 - ON [MAG.PKUP.]: Connects a 0.1 µf damping input capacitor from input
to common. This capacitor is used mostly with magnetic pickup inputs

The fourth and fifth digits show the setting for the Decimal Point select DIP
switches. (The fourth position digit represents DIP switch 4 and the fifth
position digit represents DIP switch 5.) The state of these digits coincides with
the table listed under the “Decimal Point Selection” section.
The last digit will always show a
9 10 11 12 (DIP SWITCH)
one. The next three groups are Group 2: 0 0 X X X X
shown on the right, and correspond
5 6 7 8 (DIP SWITCH)
to the DIP switch shown directly Group 3: 0 0 X X X X
1 2 3 4 (DIP SWITCH)
above it. (Note: The first two digits
in each group are always shown as Group 4: 0 0 X X X X
zeros.)
The X’s represent a zero or one (depending on the setting of the DIP switch)
in the display. Self-test is automatically exited 8 seconds after the last DIP
switch is changed.
EMC INSTALLATION GUIDELINES
Although this unit is designed with a high degree of immunity to
ElectroMagnetic Interference (EMI), proper installation and wiring methods
must be followed to ensure compatibility in each application. The type of the
electrical noise, source or coupling method into the unit may be different for
various installations. In extremely high EMI environments, additional measures
may be needed. Cable length, routing and shield termination are very important
and can mean the difference between a successful or a troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. The unit should be mounted in a metal enclosure, that is properly connected
to protective earth.
a. If the bezel is exposed to high Electro-Static Discharge (ESD) levels,
above 4 Kv, it should be connected to protective earth. This can be done
by making sure the metal bezel makes proper contact to the panel cut-out
or connecting the bezel screw with a spade terminal and wire to protective
earth.
2. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in
order of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the unit and leave the other end of the
shield unconnected and insulated from earth ground.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
4. Signal or Control cables within an enclosure should be routed as far away as
possible from contactors, control relays, transformers, and other noisy
components.
5. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible.
Loop the cable through the core several times or use multiple cores on each
cable for additional protection. Install line filters on the power input cable to
the unit to suppress power line interference. Install them near the power entry
point of the enclosure. The following EMI suppression devices (or
equivalent) are recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC #FCOR0000)
TDK # ZCAT3035-1330A
Steward #28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC #LFIL0000)
Schaffner # FN670-1.8/07
Corcom #1VB3
Corcom #1VR3
Note: Reference manufacturer’s instructions when installing a line filter.
6. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
WIRING CONNECTIONS
As depicted in the drawing showing the rear view of the Apollo Time
Interval Rate Indicator, there is a terminal block where all wiring connections
are made. All conductors should meet voltage and current ratings for each
terminal. Also cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that power supplied
to the unit (AC or DC) be protected by a fuse or circuit breaker. Remove the
block for easy access to the terminal screws. To remove the block, pull from the
back of the block until it slides clear of the terminal block shroud.
Enclosed with the PBLRI module is an adhesive backed label(s) showing the
terminal block pin-out. This label is for wiring reference only, do not use for
specifications. This label should be applied to the appropriate location by the
user.
CAUTION: The terminal block should NOT be removed with
power applied to the unit. The module should not be removed from
the LDD with power applied to the LDD or the module.
Terminal 3 is the “DC” (+12 V) terminal. This terminal is for sensor supply
and can provide up to 100 mA of current. An external +11 V to +14 VDC can
also be applied to this terminal to power the unit in the absence of A.C. power.
Terminal 4 is the “COMM.” (common) terminal, which is the common line
to which the sensor and other input commons are connected.
Terminal 5 is the “SIG. IN” (signal in) terminal. When the signal at this
terminal goes low, a count will be registered in the unit. (See “Input Ratings”
under “Specifications” section.)
POWER WIRING (A.C. Version)
Primary AC power is connected to Terminals 1 and 2 (marked VAC 50/60
Hz, located on the left-hand side of the block). For best results, the AC power
should be relatively “clean” and within the specified ±10% variation limit.
Drawing power from heavily loaded circuits or from circuits that also power
loads that cycle on and off, should be avoided.
POWER WIRING (APLRI D.C. Version only)
The DC Version unit will operate from a 24 VDC power supply. The positive
wire of the DC power source connects to Terminal #1 and the minus “-” to
Terminal #2.

INSTALLATION ENVIRONMENT
RATE MULTIPLIER SELECTION PROCEDURE
The unit should be installed in a location that does not exceed the maximum
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
The APLRI/PBLRI has a rate multiplier selection range from 1 to 8191. For
the minimum scaled reading (direct readout of the input rate), the x1 DIP
switch would be set to “ON”. For the maximum scaled reading (8191 times the
input rate), all of the rear panel RMIT DIP switches would be turned “ON”.
Therefore, a specific Rate Multiplier Increment Total is achieved by adding up
the appropriate individual rate multiplier values.
The rate multiplier increment total is computed according to the following
formula:
RATE MULTIPLIER INCREMENT = Display Readout Desired
TOTAL (RMIT)
(Known Input Pulse Rate)*
* - Input Pulse Rate Per Second (set RPS/RPM switch to RPS) or Input Pulse
Rate Per Minute (set RPS/RPM switch to RPM).

KNOWN INPUT PULSE RATE = 3PPS
RPS/RPM set to RPS

round to the nearest
RMIT =  = 1566.66

3
The appropriate rate multiplier switches, which together add up to 1,567 are
then set “ON”.
Start by selecting the first increment which is greater than half the desired
RMIT, and add subsequent increments that are more than half the difference
needed.

INSTALLATION
PBLRI installation information is contained in the LDD bulletin. Refer to
that bulletin for instructions on installing the module.
The unit meets NEMA 4/IP65 requirements for indoor use when properly
installed. The units are intended to be mounted into an enclosed panel. Two
mounting clips and screws are provided for easy installation. Consideration
should be given to the thickness of the panel. A panel which is too thin may
distort and not provide a water-tight seal. (Recommended minimum panel
thickness is 1/8".)
Cut the panel opening to the specified dimensions. Remove burrs and clean
around the panel opening. Slide the panel gasket over the rear of the unit to the
back of the bezel. Insert the unit into the panel cutout.
As depicted in the drawing, install the screws into the narrow end of the
mounting clips. Thread the screws into the clips until the pointed end just
protrudes through the other side. Install each of
the mounting clips by inserting the wide lip of
the clips into the wide end of the hole,
located on either side of the case. Then
snap the clip onto the case.
Tighten the screws evenly to apply
uniform compression, thus providing a
water-tight seal. CAUTION: Only
minimum pressure is required to seal
panel. Do NOT overtighten screws.

If the input pulse rate was known in Rate Per Minute (60 x RPS), the
RPS/RPM switch would be set to RPM and the calculations would be as
follows.

Therefore, DIP switches 2, 4, and 5, would be set to “ON”, and the RPS/RPM

EXAMPLE 2:
DISPLAY READOUT DESIRED = 432,000 bolts per day
INPUT PULSE RATE PER SECOND = 5 bolts (pulses) per sec.
Since the value to be displayed in this example is so large, the input rate was
converted to rate per minute (5 x 60 = 300 BPM) and the RPS/RPM switch was
set to RPM. The following calculations were performed:
432,000
RMIT =  = 1440
300
REAR PANEL DIP SWITCHES
As can be seen from the rear panel of the unit, there is a row of 14 DIP
switches located beside the input and power terminal block. DIP switches 1
through 13 are Rate Multiplier Increment Total (RMIT) switches. When the
switch is “ON”, it will multiply the input rate by the rate multiplier value it
represents.
DIP switch 14 is the Rate Per Second (RPS)/Rate Per Minute (RPM) DIP
switch. When the switch is “OFF”, the unit is set up for input pulse rate in RPS.
When the switch is “ON”, the unit is set up for input pulse rate in RPM. In
actuality, the RPS/RPM switch is a x 60 multiplier (It will multiply the input rate
by a value of 60). In other words, if the input pulse rate is known per second,
and the rate lies between .1 pulses/sec. and 10,000 pulses/sec., set DIP switch
14 to RPS. If the input pulse rate is known per minute, and the rate lies between
0.36 pulses/min. and 600,000 pulses/min., set DIP switch 14 to RPM.

SLOW TURNING SHAFT APPLICATION
The drawing shows one of the most common uses for the Model APLRI
Time Interval Rate Indicator. This is a slow turning shaft without the capability
of placing a gear on the end of the shaft (due to space limitations, size of shaft,
etc.). A PSAC is used to sense the keyway which is the only means of picking
up a signal from the shaft. The shaft turns at speeds from 0.5 RPM to 10 RPM
with an average speed of 5 RPM. The foreman wants to know the rate, in cases
of motor parts per shift, in which the assembly line is moving. At the average
speed of the shaft, the display reading would be 1918 cases/shift. The formula
is then used to figure out the required multiplier:
RMIT =
Display Readout Desired × D.P.

D.P. : Decimal Point
Use one of the following numbers in the above formula for the decimal point

DISPLAY READOUT DESIRED = 1918 cases/shift
INPUT PULSE RATE = 5 PPM*
* Note: Since the input rate is in RPM, set the RPS/RPM switch to RPM. Also,
since the input pulse rate could go below and usually is below 0.1 pulses/sec.,
the RPS/RPM switch must be set to RPM. Therefore,

DESCRIPTION
CONTACT TACHOMETER SPECIFICATIONS
The CONTACT TACHOMETER (Model HHT) incorporates precision
bearings instead of gears to ensure long life while providing minimal loading to
the rotating shaft. A built-in photo-sensor and slotted disc detect the number of
revolutions for a high degree of accuracy. By simply pressing the “MEASURE”
button and lightly contacting the conical tip against the center hole of a rotating
shaft, the RPM will be displayed and updated every second. By attaching the
circumferential speed wheel (included), the Model HHT can measure surface
speed in “Switch Selectable” units of either feet per minute (FT/MIN) or meters
per minute (M/MIN).
The PHOTO TACHOMETER (Model HHTP) provides for non-contact RPM
measurements which enhances operator safety when measuring high speed
shafts. By pressing the “MEASURE” button and aiming the Visible Light Beam
at a piece of reflective tape (included) on the rotating shaft, RPM will be
displayed and updated every second. A display indicator blinks once each
revolution to ensure that the reflecting mark is within the 2” to 12” sensing
distance of the Model HHTP.
Both units can display Memory values which are obtained immediately
before turning off the “MEASURE” button. The last value, Maximum value
and Minimum value can be displayed by pushing the “MEMORY” button as

DESCRIPTION
RUN

FAST STOP
JOG
OPEN LOOP
The Motor Drive Controller (MDC) regulates motor speed by varying an
isolated DC control signal to the motor drive system. There are two modes of
operation, Master and Follower.
Master Mode provides control of a motor’s speed directly via programmed
speed setpoints in the MDC. Regulation is maintained by a feedback frequency
to the MDC taken from the motor shaft or a downstream shaft pulse encoder.
Follower Mode controls a motor’s speed as a ratio to a second motor’s speed or
outside frequency source. Ratio setpoints are programmed into the MDC
causing the motor to “follow” the lead motor or frequency at a fixed speed ratio.
Master Mode has two speed setpoints and two ramp setpoints. Follower
Mode has two ratio setpoints and two ratio ramp setpoints. Both modes share a
jog speed setpoint, a jog ramp setpoint, two alarm values and a gain value. All
setpoints are retained in non-volatile memory when the unit is powered down.
The Motor Drive Controller has the added feature of allowing real time
adjustment of the Speed (Master Mode) or Ratio (Follower Mode) setpoint
while the unit is operating a motor drive system. The setpoint may be adjusted
via the front panel keypad using the “Up” or “Down” arrow keys, or via 2 User
Inputs programmed for increment setpoint and decrement setpoint.
User flexibility is provided through the two-line by eight-character
alphanumeric display. The display features English language menus for easy
viewing and simplified programming. The four scroll-through indication
displays can be programmed to show various parameters and to automatically
scroll, if desired. A program disable DIP switch used with an external User
Input can be utilized to protect the settings and guarantee that no unwanted
changes occur during operation.
DIMENSIONS “In inches (mm)”
There are six programmable control inputs: two front panel function keys and
four remote user inputs. The F1 and F2 keys are factory programmed for RUN
and R-STOP respectively. This eliminates the need for external switches in
some applications.
There are three solid state outputs, two are programmable alarms and one is
a dedicated Drive Enable output. Programmable alarm functions include:
High Alarm
Low Alarm
Deviation Alarm
Zero Speed
Disabled
These may be programmed for boundary or latching operation, high or low
acting.
Changing speed setpoints and programming information is easily
accomplished by scrolling through menus and selecting the correct parameter.
There are three main modules or menu loops:
Display Module
User Setpoint Module
Programming Module
Scaling is accomplished by entering the desired values for feedback pulses
per revolution (PPR), the maximum RPM, and the maximum display value.
Note: Recommended minimum clearance (behind the panel) for
mounting clip installation is 3.0” (76.2) H x 4.0” (101.6) W.

A fertilizer production facility is mixing pellets containing Nitrogen with
pellets that contain Phosphorus. A chemical ratio of 1:1 is determined by the
speed of two different conveyors. Because of differences in the gearing of
the conveyor and concentration of the pellets, the Nitrogen conveyor motor
must run at 3 times the speed of the Phosphorus conveyor motor in order to
produce a 1:1 mixture. The maximum speed of both motors is 2000 RPM.
Set the follower MDC scaling to produce a 1:1 mixture of Nitrogen and
Phosphorus when a setpoint of 1.0000 is entered. Display speed units are in
RPM’s. Both the lead and feedback frequency are taken from 60 tooth gears
on each motor shaft.

USER SETTINGS
The operator can reset ALL parameters to the factory settings if desired.
1) Choose the Phosphorus conveyor motor for the follower MDC. It runs
slower than the Nitrogen conveyor motor.
2) Set the Pulses per revolution feedback to 60.
3) Set the MAX RPM feedback to 2000. This is the conveyor motor’s
maximum operating speed.
4) Set display decimal point to 0.
5) Set display unit to 2000. The display speed unit maximum is 2000 at a
MAX RPM FB of 2000. If the display units wanted were conveyor
feet/minute or Phosphorus pellets in lbs/sec, the equivalent display value
for 2000 RPM would be entered.
6) Set the pulses per revolution lead to 60.
7) Setting the MAX RPM Lead:
PROGRAM DIAGNOSTICS
This allows testing of the various MDC inputs and outputs. It is especially
useful after unit installation to independently test the operation of external
switches, relays, the feedback transducer, and the motor drive system.
Inputs - The MDC displays an alphanumeric character to indicate a Dedicated
Function Input or a User Input is active. This allows the user to check switch
operation and wiring connections to the Inputs.
Alarm Outputs - The up and down arrow keys are used to select an alarm
output and set it to the active or inactive state. This allows the user to check
the operation of devices wired to the alarm outputs and the wiring
connections.
Drive Output - This function allows the user to test the Drive System. A %
Output value is entered through the front panel keypad causing the motor to
run at the corresponding open loop speed. The display indicates the motor’s
feedback frequency.
This is the Lead RPM that would be necessary to have a 1:1 mixture if
the Follower Speed was MAX RPM FB (2000 RPM). Since the Nitrogen
conveyor motor must run 3 times as fast as the Phosphorus motor, MAX
RPM LD = 3 * 2000 = 6000 RPM. Set MAX RPM LD = 6000 RPM. This
is the correct value, even though the Nitrogen conveyor motor would never
actually run at 6000 RPM. A ratio setpoint of 1.0000 on the MDC is now
equal to a 1:1 mixture of Phosphorus and Nitrogen.
PROGRAM SECURITY
The programmable code number is used in conjunction with the program
disable DIP switch and/or a user input programmed for the program disable
function to limit operator access to programming.
MASTER MODE APPLICATION
A pump delivers a maximum of 30.0 gallons per minute with a shaft speed of
1750 RPM. A shaft pulse encoder generates 60 pulses/revolution. Set the MDC
scaling to control and display pumping speed in tenths of a gallon/minute. In the
Program Scaling Module:
1) Set the pulses per revolution feedback to 60.
2) Set the maximum RPM feedback to 1750. This is the pump shaft’s maximum
operating speed.
3) Set display decimal point to 0.0. Display units are in 0.1 gpm.
4) Set max display units to 30.0. The display speed unit maximum is 30.0 at a MAX
RPM FB of 1750.

GENERAL DESCRIPTION
through the bus. Additionally, the meters have a feature that allows a remote
computer to directly control the outputs of the meter. With an RS232 or RS485
card installed, it is possible to configure the meter using Red Lion’s Crimson
software. The configuration data can be saved to a file for later recall.
A linear DC output signal is available as an optional Plug-in card for the PAXI
only. The card provides either 20 mA or 10 V signals. The output can be scaled
independent of the input range and can track any of the counter or rate displays.
Once the meters have been initially configured, the parameter list may be
locked out from further modification in its entirety or only the setpoint values
can be made accessible.
The meters have been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects to CE
requirements, the meter provides a tough yet reliable application solution.
The PAX Digital Input Panel Meters offer many features and performance
capabilities to suit a wide range of industrial applications. Available in three
different models, PAXC Counter/Dual Counter, PAXR Rate Meter and the PAXI
which offers both counting and rate in the same package. Refer to pages 4 - 5 for
the details on the specific models. The PAXC and PAXR offer only the Setpoint
Option, while the PAXI is the fully featured version offering all the capabilities
as outlined in this bulletin as well as a slave display feature. The optional plugin output cards allow the opportunity to configure the meter for present
applications, while providing easy upgrades for future needs.
The meters employ a bright 0.56" LED display. The meters are available with
a red sunlight readable or standard green LED display. The intensity of the
display can be adjusted from dark room applications up to sunlight readable,
making it ideal for viewing in bright light applications.
The meters accept digital inputs from a variety of sources including switch
contacts, outputs from CMOS or TTL circuits, magnetic pickups and all
standard RLC sensors. The meter can accept directional, uni-directional or
Quadrature signals simultaneously. The maximum input signal varies up to 34
KHz depending on the count mode and function configurations programmed.
Each input signal can be independently scaled to various process values.
The Rate Meters provide a MAX and MIN reading memory with
programmable capture time. The capture time is used to prevent detection of false
max or min readings which may occur during start-up or unusual process events.
The meters have four setpoint outputs, implemented on Plug-in option cards.
The Plug-in cards provide dual FORM-C relays (5A), quad FORM-A (3A), or
either quad sinking or quad sourcing open collector logic outputs. The setpoint
alarms can be configured to suit a variety of control and alarm requirements.
Communication and Bus Capabilities are also available as option cards for
the PAXI only. These include RS232, RS485, Modbus, DeviceNet, and
Profibus-DP. Readout values and setpoint alarm values can be controlled
DIMENSIONS In inches (mm)
SAFETY SUMMARY

equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this meter to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the meter.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
CAUTION: Risk of electric shock.

1.0 INSTALLING
METER
THE
Installation
While holding the unit in place, push the panel latch over the rear of the unit
so that the tabs of the panel latch engage in the slots on the case. The panel
latch should be engaged in the farthest forward slot possible. To achieve a
proper seal, tighten the latch screws evenly until the unit is snug in the panel
(Torque to approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws.
The PAX meets NEMA 4X/IP65 requirements when properly installed. The
unit is intended to be mounted into an enclosed panel. Prepare the panel cutout
to the dimensions shown. Remove the panel latch from the unit. Slide the panel
gasket over the rear of the unit to the back of the bezel. The unit should be
installed fully assembled. Insert
the unit into the panel cutout.
Installation Environment
The unit should be installed in a location that does not exceed the operating
temperature and provides good air circulation. Placing the unit near devices
that generate excessive heat should be avoided.
The bezel should only be cleaned with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the
keypad of the unit.

Warning: Exposed line voltage exists on the circuit boards. Remove
all power to the meter and load circuits before accessing inside of
the meter.
To access the jumper and switches, remove the meter base from the meter
case by firmly squeezing and pulling back on the side rear finger tabs. This
should lower the latch below the case slot (which is located just in front of the
finger tabs). It is recommended to release the latch on one side, then start the
other side latch.
2.1 SETTING THE JUMPER
2.2 SETTING THE INPUT DIP SWITCHES
The meter has one jumper for user input logic. When using the user inputs
this jumper must be set before applying power. The Main Circuit Board figure
shows the location of the jumper and DIP switch.
The user input jumper determines signal logic for the user inputs, when they
are used with user functions or for input signal direction. All user inputs are set
by this jumper.
The meter has six DIP switches for Input A and Input B terminal set-up that
must be set before applying power. NOTE: The PAXR only uses switches 1-3.

3.0 INSTALLING PLUG-IN CARDS
To Install:
The Plug-in cards are separately purchased optional cards that perform
specific functions. These cards plug into the main circuit board of the meter. The
Plug-in cards have many unique functions when used with the PAX. The
literature that comes with these cards should be discarded, unless it specifically
states in the Plug-in Card literature that the information applies to the PAX.
Note: The PAXC and PAXR only use the setpoint option card.
1. With the case open, locate the Plug-in card connector for the card type to be
installed. The types are keyed by position with different main circuit board
connector locations. When installing the card, hold the meter by the rear
terminals and not by the front display board.*
2. Install the Plug-in card by aligning the card terminals with the slot bay in the
rear cover. Be sure the connector is fully engaged and the tab on the Plug-in
card rests in the alignment slot on the display board.
3. Slide the meter base back into the case. Be sure the rear cover latches fully
into the case.
4. Apply the Plug-in card label to the bottom side of the meter in the designated
area. Do Not Cover the vents on the top surface of the meter. The surface of
the case must be clean for the label to adhere properly.
CAUTION: The Plug-in card and main circuit board contain
static sensitive components. Before handling the cards, discharge
static charges from your body by touching a grounded bare metal
object. Ideally, handle the cards at a static controlled clean
workstation. Also, only handle the cards by the edges. Dirt, oil or
other contaminants that may contact the cards can adversely
affect circuit operation.

4.0 WIRING
THE
METER
WIRING OVERVIEW
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the meter and leave the other end of the
shield unconnected and insulated from earth ground.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be ran in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
4. Signal or Control cables within an enclosure should be routed as far as possible
from contactors, control relays, transformers, and other noisy components.
5. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional
protection. Install line filters on the power input cable to the unit to suppress
power line interference. Install them near the power entry point of the
enclosure. The following EMI suppression devices (or equivalent) are
recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC# FCOR0000)
TDK # ZCAT3035-1330A
Steward # 28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC# LFIL0000)
Schaffner # FN670-1.8/07
Corcom # 1 VR3
Note: Reference manufacturer’s instructions when installing a line filter.
6. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
7. Switching of inductive loads produces high EMI. Use of snubbers across
inductive loads suppresses EMI.
Snubber: RLC# SNUB0000.
Electrical connections are made via screw-clamp terminals located on the
back of the meter. All conductors should conform to the meter’s voltage and
current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that the power
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.
When wiring the meter, compare the numbers embossed on the back of the
meter case against those shown in wiring drawings for proper wire position.
Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded
wires should be tinned with solder.) Insert the lead under the correct screwclamp terminal and tighten until the wire is secure. (Pull wire to verify
tightness.) Each terminal can accept up to one #14 AWG (2.55 mm) wire, two
#18 AWG (1.02 mm), or four #20 AWG (0.61 mm).
EMC INSTALLATION GUIDELINES
Although this meter is designed with a high degree of immunity to ElectroMagnetic Interference (EMI), proper installation and wiring methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, source or coupling method into the meter may be different for various
installations. The meter becomes more immune to EMI with fewer I/O
connections. Cable length, routing, and shield termination are very important
and can mean the difference between a successful or troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. The meter should be mounted in a metal enclosure, which is properly
connected to protective earth.
2. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in order
of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).

4.2 USER INPUT WIRING
Before connecting the wires, the User Input Logic Jumper should be verified for proper position. If User Input 1

4.3 INPUT WIRING
CAUTION: Sensor input common is NOT isolated from user input common. In order to preserve the safety of the meter application, the sensor input
common must be suitably isolated from hazardous live earth referenced voltage; or input common must be at protective earth ground potential. If not,
hazardous voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the potential
of the user input common with respect to earth ground; and the common of the isolated plug-in cards with respect to input common.
If you are wiring Input B, connect signal to Terminal 6 instead of 5, and set DIP switches 4, 5, and 6 to the positions shown for 1, 2, and 3.

4.5 PAXI SERIAL COMMUNICATION WIRING
RS232 Communications
RS485 Communications
The RS485 communication standard allows the connection of up to 32
devices on a single pair of wires, distances up to 4,000 ft. and data rates as high
as 10M baud (the PAX is limited to 19.2k baud). The same pair of wires is used
to both transmit and receive data. RS485 is therefore always half-duplex, that is,
data cannot be received and transmitted simultaneously.

RS232 is intended to allow two devices to communicate over distances up to
50 feet. Data Terminal Equipment (DTE) transmits data on the Transmitted Data
(TXD) line and receives data on the Received Data (RXD) line. Data Computer
Equipment (DCE) receives data on the TXD line and transmits data on the RXD
line. The PAX emulates a DTE. If the other device connected to the meter also
emulates a DTE, the TXD and RXD lines must be interchanged for
communications to take place. This is known as a null modem connection. Most
printers emulate a DCE device while most computers emulate a DTE device.
Some devices cannot accept more than two or three characters in succession
without a pause in between. In these cases, the meter employs a busy function.
As the meter begins to transmit data, the RXD line (RS232) is monitored to
determine if the receiving device is “busy”. The receiving device asserts that it
is busy by setting the RXD line to a space condition (logic 0). The meter then
suspends transmission until the RXD line is released by the receiving device.

Shaded areas represent program access that is model dependent.
PROGRAMMING MODE ENTRY (PAR KEY)
PROGRAMMING MODE EXIT (DSP KEY or at
The meter normally operates in the Display Mode. No parameters can be
programmed in this mode. The Programming Mode is entered by pressing the
PAR key. If it is not accessible then it is locked by either a security code, or a
hardware lock.
Two types of programming modes are available. Quick Programming Mode
permits only certain parameters to be viewed and/or modified. All meter
functions continue to operate except the front panel keys change to
Programming Mode Operations. Quick Programming Mode is configured in
Module 3. Full Programming Mode permits all parameters to be viewed and
modified. In this mode, incoming counts may not be recognized correctly, the
front panel keys change to Programming Mode Operations and certain user
input functions are disabled. Throughout this document, Programming Mode
(without Quick in front) always refers to “Full” Programming.
The Programming Mode is exited by pressing the DSP key (from anywhere
in the Programming Mode) or the PAR key (with
displayed). This will
commit any stored parameter changes to memory and return the meter to the
Display Mode. If a parameter was just changed, the PAR key should be pressed
to store the change before pressing the DSP key. (If power loss occurs before
returning to the Display Mode, verify recent parameter changes.)

PROGRAMMING TIPS
It is recommended to start with Module 1 for counting and Module 4 for rate.
If lost or confused while programming, press the DSP key and start over. When
programming is complete, it is recommended to record the parameter
programming on the Parameter User Chart and lock out parameter
programming with a user input or lock-out code.
The Programming Menu is organized into nine modules. These modules group
together parameters that are related in function. The display will alternate between
and the present module. The arrow keys (F1S and F2T) are used to select
the desired module. The displayed module is entered by pressing the PAR key.
Factory Settings may be completely restored in Module 9. This is a good
starting point for programming problems. Most parameters can be left at their
Factory Settings without affecting basic start-up. These parameters are
identified throughout the module explanations.
MODULE MENU (PAR KEY)
ALTERNATING SELECTION DISPLAY
In the explanation of the modules, the following dual display with arrows will
appear. This is used to illustrate the display alternating between the parameter
on top and the parameter’s Factory Setting on the bottom. In most cases,
selections and values for the parameter will be listed on the right.
Each module has a separate module menu (which is shown at the start of each
module discussion). The PAR key is pressed to advance to a particular parameter
to be changed, without changing the programming of preceding parameters.
After completing a module, the display will return to
. Programming may
continue by accessing additional modules.

SELECTION / VALUE ENTRY (ARROW & PAR KEYS)
For each parameter, the display alternates between the present parameter and
the selections/value for that parameter. The arrow keys (F1S and F2T) are used
to move through the selections/values for that parameter. Pressing the PAR key,
stores and activates the displayed selection/value. This also advances the meter
to the next parameter.
For numeric values, the RST key may be used to select a specific digit to be
changed. Once a digit is selected, the arrow keys are used to increment or
decrement that digit to the desired number.

8 DIGIT COUNT VALUES
Any counter display value below -99999 or above 999999 (less decimal
point) will consist of a two part display. This display alternates between the
least 6 significant digits and the remaining most significant digits beginning
with “ ” in the display. If the display exceeds ± 99999999 the display will roll
to zero and continue counting. Outputs cannot be set to counter values above 6
digits. The annunciator, indicating the counter being displayed, will flash when
the value is above 6 digits.
SCALING CALCULATIONS
Each counter has the ability to scale an input signal to a desired display
value. This is accomplished by the counter mode (x- ), scale factor (x
),
scale multiplier (x
) and decimal point (x
). The scale factor is
calculated using:

When Counter B is reset, it returns to zero or Counter B count load value.

1. Show feet to the hundredths (0.00) with 100 pulses per foot:
Scale Factor would be 100 / (100 x 1 x 1) = 1
(In this case, the scale multiplier and counter mode factor are 1)
2. Show feet with 120 pulses per foot: Scale Factor would be 1 / (120 x 1 x 1)
= 0.0083333. (In this case, the scale multiplier of 0.01 could be used: 1 / (120
x 1 x 0.01) = 0.83333 or show to hundredths (0.00): 100 / (120 x 1 x 1) =
0.8333.)
The number of input counts is multiplied by the scale factor and the scale
multiplier to obtain the desired process value. A scale factor of 1.00000 will
result in the display of the actual number of input counts. (Details on scaling
calculations are explained at the end of this section.)
General Rules on Scaling
COUNTER B SCALE MULTIPLIER *
1. It is recommended that, the scale factor be as close as possible to, but not
exceeding 1.00000. This can be accomplished by increasing or decreasing
the counter decimal point position, using the scale multiplier, or selecting a
different count mode.
2. To double the number of pulses per unit, use counter modes direction X2 or
quad X2. To increase it by four times, use counter mode quad X4. Using
these modes will decrease the maximum input frequency.
3. A scale factor greater than 1.00000 will cause Counter display rounding. In
this case, digit jumps could be caused by the internal count register rounding
the display. The precision of a counter application cannot be improved by
using a scale factor greater than 1. 00000.
4. The number of pulses per single unit must be greater than or equal to the
DDD value for the scale factor to be less than or equal to one.
5. Lowering the scale factor can be accomplished by lowering the counter
decimal position. (Example: 100 (Hundredths)/10 pulses = 10.000 lowering
to 10 (Tenths)/10 = 1.000.)
«
ª
The number of input counts is multiplied by the scale multiplier and the scale
factor to obtain the desired process value. A scale multiplier of 1 will result in
only the scale factor affecting the display. (Details on scaling calculations are
explained at the end of this section.)

6.2 MODULE 2 - USER INPUT AND FRONT PANEL FUNCTION KEY
PARAMETERS (
)
PARAMETER MENU
EXCHANGE PARAMETER LISTS
Module 2 is the programming for rear terminal user inputs and front panel
function keys.
Three rear terminal user inputs are individually programmable to perform
specific meter control functions. While in the Display Mode, the function is
executed when the user input transitions to the active state. (Refer to the user
input specifications for active state response times.) Certain user input functions
are disabled in “full” Programming Mode.
Three front panel function F1, F2 and RST keys are also individually
programmable to perform specific meter control functions. While in the Display
Mode, the primary function is executed when the key is pressed. Holding the
F1 and F2 function keys for three seconds executes a secondary function. It is
possible to program a secondary function without a primary function. The front
panel key functions are disabled in both Programming Modes.
In most cases, if more than one user input and/or function key is programmed
for the same function, the maintained (level trigger) actions will be performed
while at least one of those user inputs or function keys are activated. The
momentary (edge trigger) actions are performed every time any of those user
inputs or function keys transition to the active state. All functions are available
to both user inputs and function keys.
Some of the user functions have a sublist of parameters. The sublist is
accessed when PAR is pressed at the listed function. The function will only be
performed for the parameters entered as
. If a user input or function key is
configured for a function with a sublist, then that sublist will need to be scrolled
through each time to access the following user inputs or function keys
parameters.

Non-linear Application – Up to 10 Scaling Points
Module 4 is the programming for the Rate parameters. For maximum input
frequency, Rate assignment should be set to

Non-linear processes may utilize up to nine segments (ten scaling points) to
provide a piece-wise linear approximation representing the non-linear function.
The Rate display will be linear throughout each individual segment (i.e.
between sequential scaling points). Thus, the greater the number of segments,
the greater the conformity accuracy. Several linearization equations are
available in the SFPAX software.
PAXI: RATE ASSIGNMENT
About Scaling Points
«
Each Scaling Point is specified by two programmable parameters: A desired
Rate Display Value (
) and a corresponding Rate Input Value (
).
Scaling points are entered sequentially in ascending order of Rate Input Value.
Two scaling points must be programmed to define the upper and lower
endpoints of the first linear segment. Setting
, automatically factory sets
the first scaling point to 0.0 for typical single segment, zero based applications.
When multiple segments are used, the upper scaling point for a given segment
becomes the lower scaling point for the next sequential segment. Thus, for each
additional segment used, only one additional scaling point must be programmed.
The following chart shows the Scaling Points, the corresponding Parameter
mnemonics, and the Factory Default Settings for each point.

The Low Update Time is the minimum amount of time between display
updates for the Rate display. Values of 0.1 and 0.2 seconds will update the
display correctly but may cause the display to appear unsteady. The factory
setting of 1.0 will update the display every second minimum.

The High Update Time is the maximum amount of time before the Rate
display is forced to zero. (For more explanation, refer to Input Frequency
Calculation.) The High Update Time must be higher than the Low Update Time
and higher than the desired slowest readable speed (one divided by pulses per
second). The factory setting of 2.0, will force the display to zero for speeds
below 0.5 Hz or a pulse every 2 seconds.

RATE SCALING
To scale the Rate, enter a Scaling Display value with a corresponding Scaling
Input value. (The Display and Input values can be entered by Key-in or Applied
Methods.) These values are internally plotted to a Display value of 0 and Input
value of 0 Hz. A linear relationship is formed between these points to yield a
rate display value that corresponds to the incoming input signal rate. The PAXI
and PAXR are capable of showing a rate display value for any linear process.

Enter the corresponding Rate Input Value for the second Scaling Point by
using the arrow keys. Rate Input values for scaling points can be entered by
using the Key-in or the Applied method described below.
KEY-IN SCALING METHOD CALCULATION
Key-in Method:
If a display value versus input signal (in pulses per second) is known, then
those values can be entered into Scaling Display (
x) and Scaling Input
(
x). No further calculations are needed.
If only the number of pulses per ‘single’ unit (i.e. # of pulses per foot) is
known, then it can be entered as the Scaling Input value and the Scaling Display
value will be entered as the following:
Enter the Rate Input value (
) that corresponds to the entered Rate
Display value (
) by pressing the F1 or F2 keys. This value is always in
pulses per second (Hz).
Applied Method:
Apply an external rate signal to the appropriate input terminals. At the Rate
Input Value (
) press and hold the F1 and F2 keys at the same time. The
applied input frequency (in Hz) will appear on the display. (To verify correct
reading wait for at least the length of the Low Update Time. Then press and
hold the F1 and F2 keys at the same time again. The new value should be ±
0.1% of the previous entered value.) Press PAR to enter the displayed
frequency as the Rate Input value. To prevent the displayed value from being
entered, press DSP. This will take the meter out of Programming Mode and the
previous Rate Input value will remain.

Rounding values other than one round the Rate display to the nearest

The meter determines the input frequency by summing the number of falling
edges received during a sample period of time. The sample period begins on the
first falling edge. At this falling edge, the meter starts accumulating time
towards Low Update and High Update values. Also, the meter starts
accumulating the number of falling edges. When the time reaches the Low
Update Time value, the meter looks for one more falling edge to end the sample
period. If a falling edge occurs (before the High Update Time value is reached),
the Rate display will update to the new value and the next sample period will
start on the same edge. If the High Update Time value is reached (without
receiving a falling edge after reaching Low Update Time), then the sample
period will end but the Rate display will be forced to zero. The High Update
Time value must be greater than the Low Update Time value. Both values must
be greater than 0.0. The input frequency calculated during the sample period, is
then shown as a Rate value determined by either scaling method.

amount of time, the meter will capture that Rate value as the new Minimum
value. A delay time helps to avoid false captures of sudden short spikes.
Minimum detection will only function if Rate is assigned to Input A or B. The
Minimum rate value is shown with an annunciator of ‘ ’ in the display and will
continue to function independent of being displayed.
RATE DISPLAY EXCEEDED
If the rate of the input signal causes a display that exceeds the capacity of the
Rate display (5 digits, 99999), then the display will indicate an overflow
condition by showing “
”. During this overflow condition, the Minimum
and Maximum rate values will stay at their values even during resets.

6.5 MODULE 5 - COUNTER C INPUT PARAMETERS (
PAXC & I
PARAMETER MENU
Module 5 is the programming for Counter C. For maximum input frequency,
the counter operating mode should be set to
when not in use. When set to
the remaining related parameters are not accessible. The C annunciator
indicates that Counter C is being shown in the Display Mode. An Exchange
Parameter List feature for scale factor and count load values is explained in
Module 2.
COUNTER C SCALE FACTOR
«
The number of input counts is multiplied by the scale factor and the scale
multiplier to obtain the desired process value. A scale factor of 1.00000 will
result in the display of the actual number of input counts. For (Numeric
transmissions) modes of operation, the input signal is scaled directly. For
and
modes of operation, the math is performed on the input signals
and then the result is scaled. To achieve correct results, both Input A and Input
B must provide the same amount of pulses per unit of measurement. (Details on
scaling calculations are explained at the end of Module 1 section.)
«
ª
Select the operating mode for Counter C.
Add Ab

COUNTER C SCALE MULTIPLIER
Counter C counts the incoming pulses from Counter A input
as per Counter A mode of operation. The signal is scaled only
according to Counter C parameters.
«
Counter C counts the incoming pulses from Counter A and B
inputs as per Counter A and B modes of operation. The result
is scaled only according to Counter C parameters. (Example:
If Counter A is set for Count X1 mode and Counter B is set
for Count X2 mode, then Counter C will increment by 1 for
each pulse received on Input A and increment by 2 for each
pulse received on Input B less any effects of scaling.)
ª
The number of input counts is multiplied by the scale multiplier and the scale
factor to obtain the desired process value. A scale multiplier of 1 will result in
only the scale factor affecting the display. (Details on scaling calculations are
explained at the end of Module 1 section.)
Counter C counts the incoming pulses from Counter A and B
inputs as per Counter A and B modes of operation and
subtracts the B counts from the A counts. The result is scaled
only according to Counter C parameters. (Example: If
Counter A is set for Count X1 mode and Counter B is set for
Count X2 mode, then Counter C will increment by 1 for each
pulse received on Input A and decrement by 2 for each pulse
received on Input B less any effects of scaling.)

6.6 MODULE 6 - SETPOINT (ALARM) PARAMETERS (
)
PARAMETER MENU
Module 6 is the programming for the setpoint (alarms) output parameters. To have setpoint outputs, a setpoint Plug-in card needs to
be installed into the PAX (see Ordering Information). Depending on the card installed, there will be two or four setpoint outputs
available. This section replaces the bulletin that comes with the setpoint plug-in card. Please discard the separate literature when using
the Plug-in card with the Digital PAX. For maximum input frequency, unused Setpoints should be configured for
action.
The setpoint assignment and the setpoint action determine certain setpoint feature availability. The chart below illustrates this.

6.7 MODULE 7 - SERIAL COMMUNICATIONS PARAMETERS (
PAXI ONLY
)
PARAMETER MENU
METER UNIT ADDRESS
Module 7 is the programming module for the Serial Communications
Parameters. These parameters are used to match the serial settings of the PAXI
with those of the host computer or other serial device, such as a terminal or
printer. This programming module can only be accessed if an RS232 or RS485
Serial Communications card is installed.
This section also includes an explanation of the commands and formatting
required for communicating with the PAXI. In order to establish serial
communications, the user must have host software that can send and receive
ASCII characters. Red Lion's SFPAX software can be used for configuring the
PAXI (See Ordering Information). For serial hardware and wiring details, refer
to section 4.5 Serial Communication Wiring.
«
to
ª
Enter the serial meter (node) address. With a single unit, an address is not
needed and a value of zero can be used. With multiple units (RS485
applications), a unique 2 digit address number must be assigned to each meter.
ABBREVIATED PRINTING
This section replaces the bulletin shipped with the RS232 and RS485 serial
communications plug-in cards. Discard the separate bulletin when using those
serial plug-in cards with the PAXI. Also, this section does NOT apply to the
DeviceNet, Modbus, or Profibus-DP communication cards. For details on the
operation of the Fieldbus cards, refer to the bulletin shipped with each card.

SENDING SERIAL COMMANDS AND DATA
Command String Examples:
1. Address = 17, Write 350 to Setpoint 1
String: N17VM350$
2. Address = 5, Read Count A value, response time of 50 - 100 msec. min.
String: N05TA*
3. Address = 0, Reset Setpoint 4 output
String: RS*
When sending commands to the meter, a string containing at least one
command character must be constructed. A command string consists of a
command character, a value identifier, numerical data (if writing data to the
meter) followed by a the command terminator character * or $. The <CR> is
also available as a terminator when Counter C is in the SLAVE mode.

Numeric data sent to the meter must be limited to Transmit Details listed in
the Register Identification Chart. Leading zeros are ignored. Negative numbers
must have a minus sign. The meter ignores any decimal point and conforms the
number to the scaled resolution. (ie. The meter’s scaled decimal point position
is set for 0.0 and 25 is written to a register. The value of the register is now 2.5.
In this case, write a value of 250 to equal 25.0).
Note: Since the meter does not issue a reply to value change commands, follow
with a transmit value command for readback verification.
Transmitting Data From the Meter
Data is transmitted from the meter in response to either a transmit command
(T), a print block command (P) or User Function print request. The response
from the meter is either a full field transmission or an abbreviated transmission.
The meter response is established in Module 7.
Command String Construction
The command string must be constructed in a specific sequence. The meter
does not respond with an error message to invalid commands. The following
procedure details construction of a command string:
Full Transmission
1. The first characters consist of the Node Address Specifier (N) followed by a
2 character address number. The address number of the meter is
programmable. If the node address is 0, this command and the node address
itself may be omitted. This is the only command that may be used in
conjunction with other commands.
2. After the optional address specifier, the next character is the command
character.
3. The next character is the Register ID. This identifies the register that the
command affects. The P command does not require a Register ID character.
It prints according to the selections made in print options.
4. If constructing a value change command (writing data), the numeric data is
sent next.
5. All command strings must be terminated with the string termination
characters *, $ or when Counter C is set for slave mode <CR>. The meter
does not begin processing the command string until this character is received.
See Timing Diagram figure for differences between terminating characters.

Writing to this register (VW) while the analog output is in the Manual Mode
causes the output signal level to update immediately to the value sent. While in
the Automatic Mode, this register may be written to, but it has no effect until the
analog output is placed in the manual mode. When in the Automatic Mode, the
meter controls the analog output signal level. Reading from this register (TW)
will show the present value of the analog output signal.
Example: VW2047 will result in an output of 10.000 mA, 12.000 mA or
5.000V depending on the range selected.
Auto/Manual Mode Register (MMR) ID: U
This register sets the controlling mode for the outputs. In Auto Mode (0) the
meter controls the setpoint and analog output. In Manual Mode (1) the outputs
are defined by the registers SOR and AOR. When transferring from auto mode
to manual mode, the meter holds the last output value (until the register is
changed by a write). Each output may be independently changed to auto or
manual. In a write command string (VU), any character besides 0 or 1 in a field
will not change the corresponding output mode.

mA, 4-20 mA or 0-10 V).
In Automatic Mode, the meter controls the setpoint output state. In Manual
Mode, writing to this register (VX) will change the output state. Sending any
character besides 0 or 1 in a field or if the corresponding output was not first in
manual mode, the corresponding output value will not change. (It is not
necessary to send least significant 0s.)
Example: VX10 will result in output 1 on and output 2 off.
COUNTER C SLAVE COMMUNICATIONS
Counter C may be programmed for
, to act as a serial slave display. By doing this, the carriage return <CR>
is added as a valid command terminator character for all serial command strings. The <CR> as a terminator may be
very useful for standard serial commands, even if Counter C is never displayed or sent a slave message. The $
terminator should not be used in the slave mode. If numeric values are not to be saved to EPROM then send the value
as a literal transmission with <CR> terminator.
The Counter C slave display is right aligned. It has a capacity of displaying six characters. When less than six
characters are received, blank spaces will be placed in front of the characters. If more than six characters are sent,
then only the last six are displayed. The meter has a 192 character buffer for the slave display. If more than 192
characters are sent, the additional characters are discarded until a terminator is received. Counter C processes
numeric and literal transmissions differently.
Numeric Transmissions
Literal Transmissions
When a string that does not begin with #, T, V, P or R is received, the meter
processes it as a Numeric transmission. In this case, only the recognized numbers
and punctuation are displayed. All other characters in the string are discarded. If
a negative sign appears anywhere in the string the resulting number will be
negative. Only the most significant decimal point is retained. If no numerical
characters are received, then the numeric value will be zero. The numeric display
can be used for setpoint (boundary action only) and analog output functions.
When using this display for setpoint and analog output values, the decimal point
position must match the programming entered through the front panel. The
numeric value is retained in Counter C memory until another Numeric
transmission is received.
When a string that begins with # is received, the meter processes it as a Literal
transmission. In this case, any unrecognized characters will be replaced with a
space. A Literal display will replace a Numeric value in the Counter C display.
However, it will not remove a previous Numeric value from Counter C memory
or prevent the Counter C outputs from functioning with the Numeric value.
Literal transmissions are only possible when using RS232 or RS485 cards.
Recognized Characters = a, b, c, d, e, f, g, h, i, j, l, n, o, p, q, r, s, t, u,
y, z (in upper or lower case)
Recognized Numbers = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Recognized Punctuation = period, comma, minus, blank

COMMAND RESPONSE TIME
SERIAL TIMING
The meter can only receive data or transmit data at any one time (half-duplex
operation). During RS232 transmissions, the meter ignores commands while
transmitting data, but instead uses RXD as a busy signal. When sending
commands and data to the meter, a delay must be imposed before sending
another command. This allows enough time for the meter to process the
command and prepare for the next command.
At the start of the time interval t1, the computer program prints or writes the
string to the com port, thus initiating a transmission. During t1, the command
characters are under transmission and at the end of this period, the command
terminating character (*, $ or slave only <CR>) is received by the meter. The
time duration of t1 is dependent on the number of characters and baud rate of
the channel.

t1 = (10 times the # of characters) / baud rate
At the start of time interval t2, the meter starts the interpretation of the
command and when complete, performs the command function. This time
interval t2 varies (See Timing Diagrams). If no response from the meter is
expected, the meter is ready to accept another command.
If the meter is to reply with data, the time interval t2 is controlled by the use
of the command terminating character. The ‘*’ or ‘<CR>’ terminating character
results in a response time window of 50 msec. minimum and 100 msec.
maximum. This allows sufficient time for the release of the sending driver on
the RS485 bus. Terminating the command line with ‘$’ results in a response
time window (t2) of 2 msec. minimum and 50 msec. maximum. The faster
response time of this terminating character requires that sending drivers release
within 2 msec. after the terminating character is received.
At the beginning of time interval t3, the meter responds with the first
character of the reply. As with t1, the time duration of t3 is dependent on the
number of characters and baud rate of the channel. At the end of t3, the meter is
ready to receive the next command.
NO REPLY FROM METER
RESPONSE FROM METER
t3 = (10 times the # of characters) / baud rate
The maximum serial throughput of the meter is limited to the sum of the
times t1, t2 and t3.
COMMUNICATION FORMAT
Data is transferred from the meter through a serial communication channel.
In serial communications, the voltage is switched between a high and low level
at a predetermined rate (baud rate) using ASCII encoding. The receiving device
reads the voltage levels at the same intervals and then translates the switched
levels back to a character.
The voltage level conventions depend on the interface standard. The table
lists the voltage levels for each standard.

* Voltage levels at the Receiver
Data is transmitted one byte at a time with a variable idle period between
characters (0 to ∞). Each ASCII character is “framed” with a beginning start bit,
an optional parity bit and one or more ending stop bits. The data format and
baud rate must match that of other equipment in order for communication to
take place. The figures list the data formats employed by the meter.
Character Frame Figure
Parity bit
After the data bits, the parity bit is sent. The transmitter sets the parity bit to
a zero or a one, so that the total number of ones contained in the transmission
(including the parity bit) is either even or odd. This bit is used by the receiver
to detect errors that may occur to an odd number of bits in the transmission.
However, a single parity bit cannot detect errors that may occur to an even
number of bits. Given this limitation, the parity bit is often ignored by the
receiving device. The PAX meter ignores the parity bit of incoming data and
sets the parity bit to odd, even or none (mark parity) for outgoing data.
Start bit and Data bits
Data transmission always begins with the start bit. The start bit signals the
receiving device to prepare for reception of data. One bit period later, the least
significant bit of the ASCII encoded character is transmitted, followed by the
remaining data bits. The receiving device then reads each bit position as they are
transmitted.
Stop bit
The last character transmitted is the stop bit. The stop bit provides a single bit
period pause to allow the receiver to prepare to re-synchronize to the start of a
new transmission (start bit of next byte). The receiver then continuously looks
for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2
stop bits are sent from the PAXI.

Analog Output Card Calibration
PAXI: CALIBRATION
Before starting, verify that a precision meter with an accuracy of 0.05% or
better (voltmeter for voltage output and/or current meter for current output) is
connected and ready. Then perform the following procedure:
1. Use the arrow keys to display
and press PAR.
2.
is displayed. Use the arrow keys to select
and press PAR.
3. Using the chart below, step through the five selections to be calibrated. At
each prompt, use the PAXI arrow keys to adjust the output so that the
external meter display matches the selection being calibrated. When the
external reading matches, or if the range is not being calibrated, press PAR.
«
The only item in the PAXI meter that can be calibrated
is the Analog Output. The Count A and B values are scaled
using the parameters in Module 1, Counter C value is scaled
using Module 5 and the Rate value is scaled using Module 4. If the meter appears
to be indicating incorrectly or inaccurately, refer to the Troubleshooting section.
When Analog Out recalibration is required (generally every 2 years), it
should be performed by qualified technicians using appropriate equipment.
Calibration does not change any user programmed parameters.
Calibration may be aborted by disconnecting power to the meter before
exiting Module 9. In this case, the existing calibration settings remain in effect.

The DITAK 3A provides a very economical means for obtaining high
performance speed or rate readout on any machine or process. It is a natural
choice for O.E.M. applications as well as for equipping existing machines or
retrofitting older equipment in the users plant. The DITAK 3A uses circuit
technology proven in tens of thousands of successful field applications. It’s
programmable input circuit allows it to be used with a wide variety of inputs
and its simplicity of design makes it very easy to install and use.
The unit has a fixed 1-second time-base that is derived from the A.C. powerline and provides readings accurate to ±0.1% (A program switch on the rear
selects 50/60 Hz operation). A 1-second display update time provides optimum
readability.
The fixed, 1-second time-base requires that input pulse rates be properly
scaled to produce a direct readout. If the rate measurement is on a 1-second
basis, such as strokes-per-second or inches-per-second, then one input pulse per
stroke or per inch will result in direct readout. If the rate measurement is on a
minute basis (ft/min, gallons/min, revolutions/min), then 60 pulses per unit-ofmeasurement are required for direct readout.

DITAK 3A TYPICAL APPLICATIONS
1. MOTOR RPM READOUT USING ARCJ NEMA C-FLANGE ADAPTER KIT
Readout of motor or shaft RPM is one of the most popular applications of
the DITAK 3A, since it is usually quite simple to locate a 60-tooth sensing
gear on the shaft to be monitored.
In this example, an ARCJ adapter ring kit is used to develop the input
signal. The ARCJ kit includes the adapter ring, magnetic pickup, and a 60-
tooth sensing gear. It can be mounted directly on a NEMA-C flange motor
face or between the motor and a mating flange on a gear reducer. (For more
information, see Sensor Section of the Catalog.)
Signal connection between the DITAK 3A and the magnetic pickup of the
ARCJ ring is via a 2-wire shielded cable.
2. READING LINEAR SPEED IN FEET/MIN, INCHES/MIN, METERS/MIN, ETC.
Rate measurement of units having a time based in minutes (gallons/ min,
feet/min, etc.) is easily accomplished, with the fixed, 1-second, up-date time
of the DITAK 3A, if the sensor arrangement yields 60 pulses/ unit-ofmeasure. Shown above is a typical application involving material length
measurement. LSC Length Sensors are available with outputs of 60 pulses/ft,
60 pulses/yard, and 60 pulses/ meter, specifically for this type of application.
As an alternate, an RPG can be belt driven from an idler roll shaft to provide
the same information rate. (See Sensor Section of the Catalog for more
information on LSC, RPG, and other sensors.)
3. OBTAINING 60 PULSES/UNIT INFORMATION RATE FROM LINE SHAFT
DITAK 3A with its 1-second time base, an information rate of 60 pulses/book
is required. As shown above, this is easily accomplished by sensing a 30tooth gear mounted on the line shaft with an LMPC sensor.
Many machines have a line shaft or an intermediate drive member that runs
at some integral speed related to the product being produced. In this example,
a book-binding machine is driven by a line shaft that makes 2 revolutions for
each book produced. The desired rate readout is in Books/Min. To use the

DESCRIPTION
The DITAK 3D provides versatility and flexibility. Based on circuit designs
and technology, this unit is field-proven for reliability in tens of thousands of
actual in-plant installations.
The key to adaptability in rate measurement, lies in the ability to scale for
direct readout in terms of the units being measured. Whether a machine
produces bottles, cloth, wire, or beverage mix, operation is enhanced when the
rate readout is expressed directly in bottles/min, feet/min, gallons/hour, or
whatever units are customarily used in plant operation. The DITAK 3D
provides this capabilty through its settable time base, programmable decimal
points and frequency doubling function.

DITAK 3D TIME BASE SETTING PROCEDURE
The Time Base is set by adding 12 binary increments from 0.001 second to
2.048 seconds. This is done by setting the switch for each increment to be added
to the “ON” (UP) position. To determine the increments required, use the
folowing procedure.
Start by selecting the first increment which is greater than half the desired
time base and add subsequent increments that are more than half the difference
needed.

For Time Bases, greater than 4.095 seconds but less than 8.190 seconds, set
up ½ the required Time Base as above and set the X2 multiplier to on. For Time
Bases greater than 8.190 seconds but less than 16.380 seconds, set up ¼ the
required Time Base and set the X4 multiplier switch on. Use the same
procedure to multiply X8 for Time Bases up to 32.76 seconds.
At least one of the four Time Base Multiplier Switches must be “ON” (UP)
for operation. If more than one is “ON”, the unit will not function properly.
When the Time Base is less than 4.095 seconds, X1 multiplier switch must be
turned “ON”.
Note: Turning “ON” the FREQUENCY DOUBLING FUNCTION will decrease
the required Time Base to ½ the time normally required.
Turning “ON” the Decimal Point switches will increase the required time
base by multiples of ten.

The procedure for setting the additive time increments to obtain this time
base is shown above. Note: The time base can be halved if FREQUENCY
DOUBLING is used.
In this example an existing timing belt pulley, in the drive train of a set of
nip-rolls, is used to excite an inexpensive magnetic pickup. Direct readout is
obtained by setting the time base to a period in which the number of teeth
passing the pickup is numerically equal to the desired readout number. This
can be worked out in logical steps as shown in the example below, but in this
case the formula at right can also be used:
60 x (Numerical Readout Desired) x DDP
Time Base (seconds) = -¾-¾¾¾(Pulses per rev.) x (RPM of gear)
2. DETERMINING TIME BASE IN A FLOW RATE APPLICATION
A turbine type flow meter uses a magnetic pickup to sense passing turbine
blades, and has a calibration factor of 677.8 pulses/gallon of fluid passing
through. It is to be used with a DITAK 3D to read directly in gallons/min in
1/100ths at flow rates to 50 GPM. The following logical steps can be used to
determine the time base setting required for direct reading:
At 50 GPM, output pulses will be 50 GPM x 677.8 pulses/gallon = 33890 pulses/min.
60
x 50.00 GPM x 100 (DDP)

33,890 pulses per minute
= 8.852 sec.
If frequency doubling is used, this time base can be further divided by 2, or
8.852/2 = 4.426 seconds.
Since this is a longer time than can be achieved by adding binary
increments alone (with X1 multiplier) it will be necessary to set the time base
at ½ the desired value and then turn “ON” the X2 multiplier switch.
4.426 = 2.213 (Binary Setting) x 2 (multiplier setting)
Time Base (seconds) =
At this flow rate the desired reading is 50.00 GPM. Set D.P.2 switch “ON”
and use Display Decimal Point value of 100.

DITAK 3A & 3D - DIGITAL RATE INDICATORS FOR ACCURATE,
CONVENIENT & ECONOMICAL SPEED READOUT IN
PRODUCTION,
LABORATORY,
MAINTENANCE,
& FIELD APPLICATIONS
Speed is one of the most fundamental measurement parameters in industry
today. It is important not only for measuring production rate, but also for
optimizing operations, improving efficiency, problem diagnosis, and
performance measurement.
RLC’s new DITAK 3A and 3D are easily adaptable to virtually any industrial
speed measuring application. They provide superior accuracy, direct reading
flexibility, and trouble-free reliability at a super-competitive price.
Whether you need rate indication for your own in-plant equipment, or you
manufacture equipment that requires rate measuring instrumentation, check out
the benefits of the new DITAK 3A and 3D.

HOW DIGITAL RATE MEASUREMENT WORKS!
A DITAK Rate Indicator (Tachometer) includes an electronic counter, a
precision time-reference circuit, a readout display, a power supply and the
necessary coordination circuitry for proper operation. It measures speed by
following the same procedure that would be used manually, i.e. it accumulates
a count of events for a specified time period. Unlike manual speed
measurement however, it is capable of very high speed operation, it
automatically takes care of the mathematics, and it operates on a continuous
recycle basis, displaying the count it received during the last measuring time
interval while it is internally accumulating new counts for the preset interval.
At the end of each interval the display is instantly updated with the latest timeinterval-count for fast, easy readout.

SCALING FOR DIRECT READING
At first glance, the process of scaling to get direct readout on a rate indicator,
may seem a bit involved. But, from the DITAK 3A and 3D examples given on
the following pages it is obvious that scaling is nothing more than a simple
exercise in elementary logic. With the DITAK 3A, scaling is simply a matter of
determining a sensor arrangement to generate the number of counts in one
second that is equal to the desired readout.
The DITAK 3D offers another degree of scaling freedom via its precision,
adjustable, time-base and by the frequency doubling function. These features
facilitate sensing from existing gear or sprocket teeth that move in a fixed but
arbitrary relationship to the desired readout.
Ideal measuring time intervals (time-base, or up-date times) for the human
observer may vary depending on the application. Where the operator is using
the rate indicator to set machine speed, the ideal time base is between one and
five seconds. Shorter time base can be annoying to the human operator due to
the rapid update. Longer time base periods can make it awkward to set machine
speed since it takes too long to observe the effect of each new speed-change
input. However, for simple monitoring applications a time-base of 20 or 30
seconds may be entirely adequate and in some cases even desirable.

DITAK 3A & DITAK 3D
SENSOR INPUT CONNECTIONS & INPUT CONFIGURATION SWITCH SET-UP
Rate indicators frequently use magnetic pickups for input devices, while
contact input is never used due to speed and contact bounce limitations.
Consequently there are basic differences between counter and rate-indicator
input circuits.
DITAK 3A and 3D both use the input circuit shown on the right. Like the SC
Counter input circuit, a Schmidt trigger amplifier is also used here. However, in
this circuit, the hysteresis level is quite small and the bias levels are significantly
different to accomodate both magnetic pickup input as well as the +5 V and
higher logic levels.
The individual functions of the input configuration switches are:
S1 - ON [MAG.PKUP.]: Connects a 0.1 µfd damping input capacitor from input
to common. This capacitor is used only with magnetic pickup inputs and
serves to filter out high-frequency noise. S1 should be set in the OFF
position when using inputs other than magnetic pickups.
S2 - ON [LOGIC]: Sets the bias reference so that input logic signals trigger
count pulses as they cross a level of approximately +1.3 V.
OFF: Sets the bias reference so that a signal of 150 mV or more will trigger
count pulses. This provides the sensitivity required for low speed
magnetic pickup inputs.
Note: Hysteresis for both S2 “ON” and “OFF” conditions is about 25 mV.
This means the difference between VIL and VIH with logic inputs (S2) is
almost insignificant and only a very small signal swing about the 1.3 V
bias level will trigger the input.
S3 - ON [NPN O.C.]: Connects a 3.9 KW pull-up load resistor for sensors or
circuits with current sink output. Sensor output must sink 4 mA @ VOL of
1 V or less.
Maximum Operating Freq.: 10 KHz, with minimum pulse width “ON” and
“OFF” times of 50 µsec.
Input Impedance: With S1 and S3 “OFF”, the resistive input impedance
exceeds 1 Megohm, as long as Terminal “C” input voltage is between zero and
+12 VDC. Beyond these levels the high and low clamping diodes come into
play.
Paralleling With SC Counter Inputs: DITAKS may be parallel connected with
SC Counters to operate from a common Current Sink or Source Sensor, by
connecting “A”, “B” and “C” terminals in common. S3 (NPN O.C.) on the
DITAK should be turned “OFF” since pull-up or pull-down resistors are
already present in the counter. The DITAK will not add appreciable sensor
loads with this arrangement.
Note: DITAKS cannot be operated in parallel with SC Counters when countswitch or 2-wire proximity sensors are used.
OTHER CHARACTERISTICS & SPECIFICATIONS
Maximum Input Voltage & Current: When the input (Term. “C”) is driven
from external signal voltages, maximum voltage swing is ±50 V peak. Input
voltage can be dropped by an external series resistance that limits input current
to ±5 mA. (These ratings for S1 & S2 ON/OFF, S3 OFF.)

carrying conductors.
3. Connect the shield to the common terminal “B” at the input of the
instrument. DO NOT connect the shield at the pickup end, leave it “open”
and insulate the exposed shield to prevent electrical contact with the
frame or case.

DITAK 5 - THE ACCURATE, ECONOMIC & EASY WAY TO MEASURE RPM, GPM, FPM . . .
INDICATE PRODUCTION RATE & DISPLAY FREQUENCY
SELF POWERED SIMPLICITY
The ultra-low power consumption of the Ditak 5 (60 microwatts) opens up
vast new application possibilities. In a great many cases the pulse signal source
itself has sufficient power content to operate the unit. Alternatively, the Ditak
5 can be equipped with batteries, or power can be supplied from an external
source.
ACCURACY
0.1% crystal controlled accuracy with digital readout provides speed
measuring precision at a low cost.
SEALED FRONT, RUGGED CONSTRUCTION
Housed in a die-cast metal case, designed for NEMA 4/IP65, the unit can be
mounted in tough, industrial environments and withstand oil or water spray.
Micro-assembly construction provides high shock and vibration resistance.
VERSATILITY
Ideal for portable and/or fixed in-plant use. Operates with +5 Volt CMOS and
TTL circuit outputs and is adaptable to electronic sensor outputs.
ADVANTAGES OF MICRO-ELECTRONICS
DESCRIPTION OF OPERATION
The Ditak 5 is a state-of the art rate measuring instrument. Its superior
performance/cost ratio sets a new benchmark for the industry. This is made
possible by the technology of micro-electronics.
Micro-electronics concentrates as much circuitry as possible into a few
monolithic LSI chips. The Ditak 5 utilizes two of these custom chips to
encompass more than 99.9% of the required circuit components. These chips
are bonded to a substrate carrier and the microscopic electrical connections are
made by ultrasonically wire-bonding the chip pads to the gold plated conductors
on the substrate. Inter-connections of separate assemblies and components such
as the LCD and batteries are accomplished by elastomeric connectors.
The Ditak 5 is a combination of a precision counter and a crystal controlled
1-second time base, with liquid crystal display. In operation, the electronic
counter accumulates incoming pulses for a period of exactly one second. At the
end of this period, the count is transferred and latched on the display.
Immediately after transferring the count to the display, the internal counter is
reset to zero and begins accumulating a new count. Consequently, the display is
updated once a second, and the readout at any one time is the numerical value
of the number of counts received in the previous 1-second interval.
The Ditak 5 is basically a frequency measuring device and can be used for
direct Hz readout. Many industrial rate parameters, however, are expressed in
terms of minutes (gallons/min., feet/min., revolutions/min., etc.) Counting these
units for a full minute before presenting a readout takes too much time and is
therefore impractical. By using a sensor arrangement that delivers 60 pulses/unit
of measure (such as a 60 tooth gear to generate 60 PPR for RPM indication), the
Ditak 5 will read out directly in the desired units with a convenient 1-second
update time.
RELIABILITY
Large scale integration achieves the ultimate in circuit reliability. The Ditak
5’s miniature size provides high immunity to shock and vibration damage.
Elastomeric (internal and battery) connections provide gas-tight, corrosionproof, sealed contacts for trouble free operation.
SMALL SIZE
Micro-electronics allows the display to become the primary determinator of
size which means cost savings in panel-shape, weight, power consumption, and
functional simplicity.
BEST PERFORMANCE/COST RATIO
Micro-electronics is inherently a highly automated technique which provides
the quality, performance, and features needed at a very low cost.

supplied in the hardware pack.
WHEN INSERTING TERMINAL into connector body, make sure the lock
pawl is toward the slot in the body. Push terminal in until lock pawl snaps
into slot.
TO REMOVE TERMINAL, insert blade of
a small screwdriver into slot of connector
body, and gently push in to disengage lock
pawl. Pull terminal out.

TYPICAL APPLICATIONS
SELF-POWERED FROM MAGNETIC PICKUP SIGNAL (Using MP62TA magnetic pickup, or ARCJ ring pickup kits)
With an MP62TA Magnetic Pickup, a 60-tooth 20 D.P. Gear, and an air gap
of 0.005", the pickup will begin to develop sufficient voltage to power the
Ditak 5 (about 3.5 V peak) at a speed of 175 to 200 RPM. See Magnetic
Pickup and ARCJ Ring Kit tables for typical minimum speed parameters of
various sizes of Magnetic Pickups and ARCJ Rings.
In this application the Magnetic Pickup supplies both the signal and
operating power for the unit. A diode bridge in the Ditak 5 rectifies the A.C.
waveform generated by the magnetic pickup to develop the +V operating
voltage. The half wave component of this A.C. is applied to the base of the
input transistor to generate count pulses. The Zener Diode (ZD) clamps +V to
6.2 V maximum.
MAGNETIC PICKUP SIGNAL INPUT WITH BATTERY OR EXTERNAL POWER (For extended low speed performance)
and ARCJ Ring tables).
When batteries are used, current is drawn from the battery only during low
speed operation. At high speeds the half-wave rectified magnetic pickup
voltage exceeds the battery voltage and the unit again becomes self-powered,
to extend battery life. (Nominal battery life, without the high speed power
contribution of the magnetic pickup is 3 to 3.5 years).
Using batteries or an external source to supply power to the Ditak 5, allows
the magnetic pickup to be used only as a signal source at low speed. By
relocating the connector terminal wires as shown above, the magnetic pickup
voltage is applied directly to the transistor input and a signal level of only 0.7
Volts peak is needed for operation. This reduces minimum operating speed to
about 25% of the level required for self-powered operation (See Mag. Pkup.
Note: Connector wire colors shown are arranged
arbitrarily - User can select any color code
scheme desired.
cable, open at the pickup end). The Ditak 5 case should be mounted in a
panel which is electrically grounded through the machine frame to the
pickup housing of the ARCJ Ring motor.
4. Magnetic Pickups have a highly inductive output impedance which limits
output voltage and current to a safe level when clamped by the internal
zener diode in the Ditak 5. Signal sources with peak voltage in excess of 6
Volts, and having low output impedance, may develop sufficient power to
damage the internal zener diode if connected directly. With this type of
signal source, use a current limiting resistor as shown in the following
application.
NOTES ON MAGNETIC PICKUPS
1. Magnetic Pickups generate voltage proportional to the size and speed of
passing gear teeth, and inversely proportional to air-gap.
2. Sensing gears used with Magnetic Pickups should run as true as possible.
Eccentricity and wobble causes voltage fluctuations that can produce
observable display “flicker” at low speeds when pickup power is being
used to operate the Ditak 5.
3. Shielded cable is recommended when using magnetic pickups. Connect the
shield to the COMMON input pin of the Ditak 5 (A spare BLUE terminal
wire in the hardware package may be used to bring out COMMON). Leave
the shield unconnected at the sensor end (MP62TA is supplied with shielded

TYPICAL APPLICATIONS (Cont’d)
VARIABLE FREQUENCY A.C. INPUTS, SIGNAL SOURCE POWERED
Capacitors shown connected to COMMON by dotted lines may be required
when A.C. voltage supply is “noisy”. Capacitor values depend on existing
conditions but values from 0.01 to 0.1 µfd are usually effective. An isolation
step-down transformer should always be used when power line or high
voltage inverter lines and being monitored.
A.C. Signal Sources can be used to operate the Ditak 5 via the Magnetic
Pickup Input without batteries or external D.C. power, down to 7 or 8 Hz
signal frequency. However, unlike magnetic pickups most A.C. signal sources
have low output impedance and require a current limiting resistor if the peak
voltage exceeds 6 volts.
Minimum VAC for operation is 3.2 V peak
Select R to limit input current to 10 mA max. at max. VAC.
LOGIC PULSE INPUTS FROM OTHER CIRCUITS & SENSORS
operate directly from the power delivered by the signal itself without batteries
or external power applied. If the signal is a narrow positive going pulse, or if
operation below 15 Hz is required, either external power should be connected
as shown, or batteries should be installed.
The Ditak 5 easily adapts to a wide variety of pulse signal inputs. The only
restriction that must be kept in mind is that a current limiting resistor must be
used in series with the input applied to “PSM IN” if the input signal voltage
exceeds +6 Volts peak (Limit input current to 10 mA peak). With square wave
inputs (50% duty cycle), at frequencies of 15 Hz and above, the Ditak 5 will

ADJUSTABLE TIMEBASE FROM 4 MSEC TO 32 SEC
!
SELECTABLE DECIMAL POINTS
!
!
DESCRIPTION
The DT6 is a self-powered tachometer which features the ability to select the
desired Timebase by simply setting the appropriate DIP switches on the rear of
the unit. It also features a 4-digit LCD display with selectable decimal points.
The DT6 is powered by an internal 3.0 V lithium battery which is field
replaceable.
Like other Micro-Line products, the DT6 combines the use of a custom
CMOS LSI counter chip and custom Timebase gate array. These chips are
mounted on a gold-plated substrate and electrically connected by ultrasonic
wirebonding. Internal electrical interface connections use elastomeric contacts
to provide a gas-tight, corrosion resistant connection. Using the latest in MicroElectronic assembly and manufacturing techniques provides units with
reliability and dependability required for industrial service. The DT6 has a
metal die-cast front bezel that is sealed and meets NEMA 4 specifications for
wash-down and/or dusty environments, when properly installed.
SPECIFICATIONS
1. DISPLAY: 4-Digit LCD, 0.35" (9mm) high digits.
2. POWER SOURCE: Internal 3.0 V lithium battery to provide up to 5 years
of continuous service. For replacement procedure, refer to the illustration.
The DT6 also receives power from a logic or magnetic input signal with a
min. peak voltage of 4.0 V, which will serve to extend the battery life.
3. SIGNAL INPUT: * 0-10 KHz from a magnetic or bi-polar output (with a
50% duty cycle). Min. input sensitivity is 0.7 V. Input signal voltages over
6 V peak require an external series resistor to limit the input current to 10 mA
max.
4. TIMEBASE: Adjustable in 1/256 sec. (3.906 msec) increments via DIP
switches located under the rear cover. Timebase ranges from 3.906 msec to
31.996 sec; 0.05% accuracy.

6. WEIGHT: 5.1 oz (146 g)
* Caution: The case of the DT6 is electrically connected to signal common.
ELECTRICAL CONNECTIONS
Since the DT6 is self powered, only two electrical connections are required.
These connections are made utilizing a 2 position terminal block, located at the
rear of the unit. Refer to the procedures below when connecting the DT6 to the
signal source.
1. Use 2-wire shielded cable for sensor signal leads.
2. Never run signal cable in conduit, troughs, or cable bundles with power
carrying conductors.
3. Connect the shield to the “COMM.” terminal at the input of the instrument.
Do NOT connect the shield at the pickup end, leave it “open” and insulate
the exposed shield to prevent electrical contact with the frame or case.
(Shielded cable, supplied on some RLC magnetic pickups, has open shield
on pickup end.)
4. The DT6 should be mounted in a panel that is electrically grounded through
the machine frame to the magnetic pickup housing.
DIMENSIONS & INSTALLATION
The Model DT6 should be mounted in a panel grounded to the machine
frame. After cutting the opening in the panel, slide the panel gasket over the
rear of the tachometer body to the back of the bezel. Then slide the
tachometer through the panel cut-out. Install mounting clips on each side of
the tachometer body with mounting screws. Make sure the side rails of the
clips fit into the recesses in the side of the tachometer body so that the “tang
ends” wedge between the panel opening and the body as the screws are
tightened.
DIMENSIONS: In inches (mm)
1. Remove rear cover by placing screwdriver in the slot and gently pushing
downward (See drawing below).
2. When replacing battery, observe proper polarity as shown in the
Application drawing.
3. Allow 32 seconds for the first update to occur after battery replacement.
Warning: Lithium battery may explode if incinerated.

REAR PANEL DIP SWITCHES
TYPICAL APPLICATION
When viewing the DT6 from the rear of the unit, there are two banks of 8
DIP switches located along the top edge of the PC board. The bank to the left
is labeled “SWA” and the bank to the right is labeled “SWB”. All of the “SWA”
switches and 5 of the “SWB” switches are used to select the desired Timebase.
The remaining switches of “SWB” are used to select “FREQUENCY
DOUBLING” and “DECIMAL POINT”.
CONVEYOR BELT SPEED INDICATOR
TIMEBASE SELECTION
The DT6 has a Timebase selection range of approximately 4 msec to 32 sec.
For the minimum Timebase setting, SWA 1 is set in the “ON” position. For the
maximum Timebase setting, all the Timebase switches are set to the “ON”
position. Therefore, a specific Timebase setting is achieved by adding the
appropriate individual Timebase increments.
The Timebase increment total is computed according to the following
formula:

The rate of a conveyor belt used to carry PC Boards through an Infra-Red
soldering chamber is variable from 0 to 10 feet per minute. The rate must
be adjusted depending on the size of the boards being soldered. The display
of the rate indicator must read in hundredths of a foot per minute.
The belt is driven by a chain and sprocket. A 26-tooth sprocket is
mounted onto the shaft of a variable speed motor. A speed of 1800 RPM
will produce a belt speed of 10 ft/min. A magnetic sensor is used to monitor
the speed of this sprocket.
The DT6 can be used to display the belt speed in this application. The
signal input of the sensor is connected to the DT6 “INPUT” terminal.
Common and the shield of the sensor are connected to the DT6 “COMM.”

DESCRIPTION
SAFETY SUMMARY
The Ditak 7 is a self-powered rate indicator which features selectable
Timebase Increments by setting the appropriate DIP switches on the rear of the
unit. The internal plug-in 3.0 VDC lithium battery, requires NO soldering,
making it easily replaceable in the field. It has a 5-digit LCD display with 0.6
inch (15.2 mm) high digits and a DIP switch selectable decimal point. The
displays are available in positive image reflective (black digits, reflective
background) or negative image transmissive (illuminated digits, dark
background) with red or yellow/green backlighting. Backlight version units
require power from an external 9 to 28 VDC supply.
Like other Micro-Line products, the Ditak 7 combines the use of a custom
CMOS LSI counter chip and custom timebase gate array. These chips are
mounted on a gold-plated substrate and electrically connected by ultrasonic
wire-bonding. Internal electrical interface connections use elastomeric contacts
to provide a gas-tight, corrosion resistant connection. Use of the latest in MicroElectronic assembly and manufacturing techniques provides units with
reliability and dependability required for industrial applications.
The unit is constructed of a lightweight, high impact plastic case with a clear
viewing window. The sealed front panel meets NEMA 4X/IP65 specifications
for wash-down and/or dusty environments, when properly installed. A Ditak 7
unit can be mounted in the same panel cut-out as the earlier Ditak 5 & 6 series
units.

WIRING CONNECTIONS
The electrical connections are made via rear screw-clamp terminals located
on the back of the unit. All conductors should meet voltage and current ratings
for each terminal. Also cabling should conform to appropriate standards of
good installation, local codes and regulations. It is recommended that power
supplied to the unit (AC or DC) be protected by a fuse or circuit breaker. When
wiring the unit, use the label to identify the wire position with the proper
function. Strip the wire, leaving approximately 1/4” bare wire exposed
(stranded wires should be tinned with solder). Insert the wire into the screwclamp terminal and tighten the screw until the wire is clamped tightly. Each
terminal can accept up to two #14 AWG wires.
The backlighting for a backlight version unit is powered between Terminal 2
(V+) and Terminal 1 (GND).
EMC INSTALLATION GUIDELINES
Although this unit is designed with a high degree of immunity to
ElectroMagnetic Interference (EMI), proper installation and wiring methods
must be followed to ensure compatibility in each application. The type of the
electrical noise, source or coupling method into the unit may be different for
various installations. In extremely high EMI environments, additional measures
may be needed. Cable length, routing and shield termination are very important
and can mean the difference between a successful or a troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
REAR PANEL DIP SWITCHES
When viewing the Ditak 7 from the rear, there are two banks of DIP
switches, with eight switches per bank, located along the top edge of the PC
board. The bank to the left is labeled SWA and the bank to the right is labeled
SWB. All of the SWA switches and five of the SWB switches are used to select
the desired Timebase. The remaining switches of SWB are used to select
Frequency Doubling and the Decimal Point position.
1. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in
order of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the unit and leave the other end of the
shield unconnected and insulated from earth ground.
2. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
3. Signal or Control cables within an enclosure should be routed as far away as
possible from contactors, control relays, transformers, and other noisy
components.
4. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through
the core several times or use multiple cores on each cable for additional
protection. Install line filters on the power input cable to the unit to suppress
power line interference. Install them near the power entry point of the
enclosure. The following EMI suppression devices (or equivalent) are
recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC #FCOR0000)
TDK # ZCAT3035-1330A
Steward #28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC #LFIL0000)
Schaffner # FN670-1.8/07
Corcom #1VR3
Note: Reference manufacturer’s instructions when installing a line filter.
5. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
Note: The model DT700000 will NOT have a screw terminal installed at Terminal
2 (V+), since it is NOT required for operation, and is not internally connected.
The DT700M00 uses the V+ screw terminal to mount the MLPS power supply.
It is not internally connected to the unit.
WARNING: Lithium battery may explode if incinerated.

TIMEBASE SELECTION
FREQUENCY DOUBLING
The Ditak 7 has a Timebase selection range from 4 msec to 32 sec. SWA 1
is set to the “ON” position for the minimum Timebase setting. SWA 1 through
SWB 5 are set to the “ON” position for the maximum Timebase setting. A
specific Timebase setting is achieved by adding the appropriate individual
Timebase increments. The Timebase increment total is computed according to
the following formula:
DR x DDP x 15,360
TIMEBASE INCREMENT TOTAL (TBIT) = ¾¾¾
RPM x PPR
DIP switch SWB 6 is the “Frequency Doubling” switch. When it is in the
“ON” position, frequency doubling is disabled. When set to the “OFF” position,
it is enabled and twice the number of input pulses are registered in the unit. This
doubling of the input rate allows the Timebase Increment Total to be halved,
thus allowing a faster update time for a given display value.

INSTALLATION ENVIRONMENT
The unit should be installed in a
location that does not exceed the
maximum operating temperature
and provides good air circulation.
Placing the unit near devices that
generate excessive heat should be
avoided.
The bezel should be cleaned only
with a soft cloth and neutral soap
product. Do NOT use solvents.
Continuous exposure to direct
sunlight may accelerate the aging
process of the bezel.
INSTALLATION
The Ditak 7 meets NEMA
4X/IP65 requirements for indoor
use, when properly installed. The
units are intended to be mounted
into an enclosed panel. A sponge
rubber gasket, mounting clip, two
screws, and nut fasteners are
provided to install and seal the unit
in the panel cut-out.
The following procedure assures proper installation:
1. Cut panel opening to specified dimensions. Remove
burrs and clean panel opening.
2. Slide the panel gasket over the rear of the unit to the
back of the bezel.
3. Slide nut fastener into slot on mounting clip and then
insert mounting screw through nut on both sides of
mounting clip. Tip of mounting screw should NOT
project through hole on clip.
4. Install Ditak unit through panel cut-out.
5. Slide mounting clip over rear of unit until clip is
against back of panel. The mounting clip and Ditak
housing have a latching feature to hold the unit in
place until tightened.
Note: Hold the Ditak front bezel in place when
sliding the mounting clip into position.
6. Alternately tighten each mounting screw to ensure
uniform gasket pressure. Visually inspect the gasket
for proper seal. The gasket should be compressed
approximately 75 to 80% of its original thickness.
7. If the gasket is not adequately compressed and the
mounting screws cannot be tightened any further,
loosen mounting screws and insure that the clip is
latched as close as possible to the panel.
8. Repeat step #6 for tightening the mounting screws.
TYPICAL APPLICATION
With these DIP switch settings, the Timebase would be approximately 1.3 sec
(328 x 0.004 = 1.312). To reduce the display update time, the “Frequency
Doubling” switch can be enabled (set to the “OFF” position). Therefore, only
half the Timebase will be necessary (164 x 0.004 = 0.656 sec.).
CONVEYOR BELT SPEED INDICATOR
It is desired to display the rate of a conveyor belt used to carry PC Boards
through an Infared soldering chamber that is variable from 0 to 10 feet per
minute. The rate must be adjusted depending on the size of the boards being
soldered. The display of the rate indicator must read in hundredths of a foot per
minute. The belt is driven by a chain and sprocket. A 26-tooth sprocket is
mounted onto the shaft of a variable speed motor. A speed of 1800 RPM will
produce a belt speed of 10 ft/min. A magnetic sensor is used to monitor the
speed of this sprocket. The Ditak 7 can be used to display the belt speed in this
application. The signal input of the sensor is connected to the Ditak 7 Terminal
3 (INP). The sensor common and shield are connected to the Ditak 7 Terminal
1 (GND). The Timebase setting is to be determined by using the formula.
