SECTION 1: PRODUCT DESCRIPTION
1.1 General
This instrument is a microprocessor based single loop controller capable of measuring,
displaying and controlling temperature, pressure, flow, and level from a variety of
inputs. Most outputs are easily tuned using the instrument Pre-Tune and Auto-Tune, or
RaPID (Response assisted PID) functions.
Control functions, alarm settings and other parameters are easily entered through the
front keypad. E2 Technology (100 year life) protects against data loss during AC power
outages.
The input is user configurable to directly connect to either thermocouple, RTD, mVDC,
VDC or mADC inputs. The instrument can operate from either a 90-264 VAC, 50/60 HZ
power supply, or optional 24V AC/DC power supply.

SECTION 2: INSTALLATION AND WIRING
2.1 Mounting
Electrical code requirements and safety standards should be observed and
installation performed by qualified personnel.
The electronic components of the instrument may be removed from the housing during
installation. To remove the components, grip the side edges of the front panel and pull
the instrument forward. During re-installation, the vertically mounted circuit boards
should be properly aligned in the housing.
Ensure that the instrument is correctly orientated. A stop will operate if an
attempt is made to insert the instrument incorrectly.
Recommended panel opening sizes are illustrated in Figure 2-1. After the opening is
properly cut, insert the instrument into the panel opening. Ensure that the panel gasket
is not distorted and that the instrument is positioned squarely against the panel. Slide
the mounting clamp into place on the instrument (see Figure 2-3) and push it forward
until it is firmly in contact with the rear face of the mounting panel.
Note: The mounting clamp tongues may engage either on the sides or the
top/bottom of the instrument housing, Therefore, when installing several
instruments side-by-side in one cut out, use the ratchets on the top/bottom faces.

2.2 Wiring Guidelines
Electrical noise is a phenomenon typical of industrial environments. The following are
guidelines that must be followed to minimize the effect of noise upon any
instrumentation.
Installation Considerations
Listed below are some of the common sources of electrical noise in the
industrial environment:
•
•
•
•
Ignition Transformers
Arc Welders
Mechanical contact relay(s)
Solenoids
Before using any instrument near the device listed, the instructions below
should be followed:
1. If the instrument is to be mounted in the same panel as any of the listed devices,
separate them by the largest distance possible. For maximum electrical noise
reduction, the noise generating devices should be mounted in a separate enclosure.
2. If possible, eliminate mechanical contact relay(s) and replace with solid state relays.
If a mechanical relay being powered by an instrument output device cannot be
replaced, a solid state relay can be used to isolate the instrument.
3. A separate isolation transformer to feed only instrumentation should be considered.
The transformer can isolate the instrument from noise found on the AC power input.
4. If the instrument is being installed on existing equipment, the wiring in the area
should be checked to insure that good wiring practices have been followed.
7
AC Power Wiring
Neutral (For 115 VAC)
It is good practice to assure that the AC neutral is at or near ground potential. To verify
this, a voltmeter check between neutral and ground should be done. On the AC range,
the reading should not be more than 50 millivolts. If it is greater than this amount, the
secondary of this AC transformer supplying the instrument should be checked by an
electrician. A proper neutral will help ensure maximum performance from the
instrument.
Wire Isolation
Four voltage levels of input and output wiring may be used with the unit:
•
•
•
•
Analog input or output (i.e. thermocouple, RTD, VDC, MVDC, or mADC)
SPDT Relays
SSR driver outputs
AC power
The only wires that should run together are those of the same category. If they need to
be run parallel with any of the other lines, maintain a minimum 6 inch space between
the wires. If wires must cross each other, do so at 90 degrees. This will minimize the
contact with each other and reduces "cross talk". "Cross Talk" is due to the EMF
(Electro Magnetic Flux) emitted by a wire as current passes through it. This EMF can
be picked up by other wires running in the same bundle or conduit.
In applications where a High Voltage Transformer is used (i.e. ignition systems) the
secondary of the transformer should be isolated from all other cables.
This instrument has been designed to operate in noisy environments, however, in some
cases even with proper wiring it may be necessary to suppress the noise at its source.
Use Of Shielded Cable
Shielded cable helps eliminate electrical noise being induced on the wires. All analog
signals should be run with shielded cable. Connection lead length should be kept as
short as possible, keeping the wires protected by the shielding. The shield should be
grounded at one end only The preferred grounding location is the sensor, transmitter or
transducer.
8
Noise Suppression At The Source
Usually when good wiring practices are followed no further noise protection is
necessary. Sometimes in severe electrical environments, the amount of noise is so
great that it has to be suppressed at the source. Many manufacturers of relays,
contactors, etc. supply "surge suppressors" which mount on the noise source.
For those devices that do not have surge suppressors supplied, RC (resistancecapacitance) networks and/or MOV (metal oxide varistors) may be added.
Inductive Coils - MOV's are recommended for transient suppression in inductive coils
connected in parallel and as close as possible to the coil. See Figure 2-4. Additional
protection may be provided by adding an RC network across the MOV.
FIGURE 2-4
Contacts - Arcing may occur across contacts when the contact opens and closes. This
results in electrical noise as well as damage to the contacts. Connecting a RC network
properly sized can eliminate this arc.
For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad
capacitor(1000volts)is recommended. For circuits from 3 to 5 amps, connect 2 of these
in parallel. See Figure 2-5, below.
9
FIGURE 2-5
2.3 Sensor Placement (Thermocouple or RTD)
Two-wire RTDs should be used only with lead lengths less than 10 feet.
If the temperature probe is to be subjected to corrosive or abrasive conditions, it should
be protected by the appropriate thermowell. The probe should be positioned to reflect
true process temperature:
•
•
In liquid media - the most agitated area
In air - the best circulated area

2.4 Input Connections
In general, all wiring connections are made to the instrument after it is installed. Avoid
Electrical Shock. AC power wiring must not be connected to the source distribution
panel until all wiring connection procedures are completed.
Caution:
This equipment is designed for installation in an enclosure which
provide adequate protection against electric shock. Local regulations regarding
electrical installation should be rigidly observed. Consideration should be given
to prevention of access to the power terminations by unauthorized authorized
personnel. Power should be connected via a two pole isolating switch (preferably
situated neat the equipment) and a 1 A fuse, as shown in Figure 2-7.
FIGURE 2-7
Main Supply
The instrument will operate on 90-264V AC 50/60 Hz line supply. The power
consumption is approximately 4 VA. If the instrument has relay outputs in which the
contacts are to carry line voltage, it is recommended that the relay contact line supply
be switched and fused in a similar manner, but separate from the instrument line
supply.
12
FIGURE 2-7A
24V Nominal AC/DC Supply
The supply connection for the 24V AC/DC option of the instrument are as shown below.
Power should be connected via a two pole isolating switch and a 315 mA slow-blow
(anti-surge type T) fuse. With the 24V AC/DC supply option fitted, these terminals will
accept the following supply voltage ranges:
24V (nominal) AC 50/60 Hz 24V (nominal) DC -
20 - 50 V
22 - 65 V

SECTION 3: OPERATION
3.1 Control Capability
The capabilities available in a specific unit are dependent upon the hardware options
specified when the instrument is ordered. Refer to Appendix E for the decoding of the
instrument model number. Current proportioning control cannot be implemented if a
current output was not ordered. The available output types and quantity of each are as
follows:
Type of Output
Quantity Available
•
•
•
Up to three
Up to three
Up to two
SPDT mechanical relay output
SSR Driver
mADC current output
3.2 Control Responses
Each instrument may be configured to provide three mode proportional control.
Proportional control is provided with Proportional Band, Integration, and Derivative
responses. The PID parameters are defined as follows:
P (Proportional)
I (integration)
D (Derivative)
Proportional Band
Automatic Reset
Rate
Out 1
Pb1
ArSt
rAtE
Out2
Pb2
ArSt
rAtE
Manual Reset is provided for use in lieu of, or in conjunction with automatic reset. A
cycle time adjustment parameter is provided for use with each time proportioning
control output.
21
3.3 Direct/Reverse Operation of Outputs
Direct operation is typically used with cooling applications. On-Off direct output(s) will
turn on when the process variable exceeds setpoint. Proportional direct output(s) will
increase the percentage of output as the process value increases within the
proportional band.
Reverse operation is typically used with heating applications. On-Off reverse output(s)
will turn off when the process variable exceeds setpoint. Proportional reverse output(s)
will decrease the percentage of output as the process value increases within the
proportional band.
Output 2 will be Direct when Output 1 is selected as Reverse, and Reverse when
Output 1 is selected as Direct.
3.4 On-Off Control
On-Off control can be implemented with SPDT relay or SSR driver output(s) by setting
the corresponding proportional band (Pb) to O.O. On-Off operation can be assigned to
Output 1 only (Output 2 not present), Output 1 AND Output 2, or Output 2 only (Output
1 is time proportional or current proportional). A hysteresis adjustment is provided for
On-Off outputs, "HySl " for Output 1 only, "HySt" for Output 1 AND Output 2, or "HyS2"
for Output 2 only. This adjustment is in % of input span and defines the bandwidth of
the hysteresis. Relay chatter can be eliminated by proper adjustment of this parameter.
When operating in On-Off control, the output(s) will turn on or off depending upon the
setpoint, the process value, and the hysteresis adjustment.
3.5 Time Proportioning Control
Time Proportioning control can be implemented with a SPDT relay or SSR driver. Time
proportioning control can be selected for either Output 1 or Output 1 and Output 2,
depending on hardware configuration. Time proportioning control is accomplished by
cycling the output on and off during a prescribed period of time when the process
variable is within the proportional band.
Ex:
Calculated output % = 40%; Cycle time adjustment = 32 seconds
Output on time =.4 x 32 = 12.8 seconds
Output off time = .6 x 32 = 19.2 seconds
22
When the unit is operating in the Control Mode, the control algorithm determines the
output % required to correct for any difference between the process value and the
setpoint. The output calculation is affected by Tune Mode parameter adjustments. See
Figure 3-1 for proportional bandwidth effect on the output.
3.6 Current Proportioning Control
Current Proportioning control can be implemented on units provided with mADC current
output(s). Current Proportioning control provides a 4 to 20 mADC or 0-20 mADC output
in response to process value and setpoint. As with Time proportioning, the calculated
output % for Current proportioning is affected by the Tune Mode parameter
adjustments.
See Figure 3-1 for proportional bandwidth effect on the output.
23
FIGURE 3-1
Proportional Band 1

3.7 Power Up Procedure
Verify all electrical connections have been properly made before applying power to the
instrument.
If the instrument is being powered for the first time, it may be desirable to disconnect
the controller output connections. The instrument will be into control following the
power up sequence and the output(s) may turn ON. During power up, a self-test
procedure is initiated during which all LED segments in the two front panel displays
appear and all LED indicators are ON. When the self-test procedure is complete, the
instrument reverts to normal operation.
Note: A delay of about 3 seconds, when power is first applied, will be
seen before the displays light up

2.
Proportional Bandwidth
A.
Proportional Bandwidth is the inverse of gain. Increased Bandwidth =
Decreased Gain
B.
Increase the Proportional Bandwidth if:
1.
The process overshoots excessively
2.
The process oscillates excessively
C.
Decrease the Proportional Bandwidth if:
1.
The process responds slowly
2.
The process fails to reach setpoint
3.

A.
Increase the Automatic Reset (decrease the time) until the process
becomes unstable, then decrease (increase the time) until stability is
restored.
B.
Be sure to allow sufficient time for the process and the instrument to
react.
4.
Rate Adjustment
A.
Rate can cause process instability. Typically add Rate as 1 /10th of the
automatic reset value.
B.
Decrease Rate if:
1.
The process overshoots/undershoots
2.
If the process oscillates excessively
5.
Manual Reset
A.
After making all other adjustments, use if an offset exists between the
setpoint and the process variable.
B.
If the process is:

6.2 Loop Alarm Enable
This parameter is the means by which the user can enable or disable the Loop Alarm.
The Loop Alarm is a special alarm which detects faults in the control feedback loop by
continuously monitoring process variable response to the control output(s).
The Loop Alarm, when enabled, repeatedly checks the control output(s) for being at the
maximum or minimum limit. If an output is found to be at the limit, the Loop Alarm
Mode starts a timer; thereafter, if the high output has not caused the process variable to
be corrected by a predetermined amount V after a time T has elapsed, the Loop Alarm
goes active. Subsequently, the Loop Alarm Mode repeatedly checks the process
variable and the control output(s). When the process variable starts to change value in
the correct sense or when the output comes below the limit, the Loop Alarm is
deactivated.
For PID control, the Loop Alarm Time T is always set to twice the value of the Auto
Reset parameter. For ON/OFF control, the user defined value of the Loop Alarm Time
Set Up parameter is used.
The value of V is dependent upon the input type:
Deg C:
Deg F:
Linear Range:
2ºC or 2.0ºC
3ºF or 3.0ºF
10 least significant display units
For single output instruments, the limits are 0% and Out 1 Max %. For dual
output instruments, the limits are -1 00% and Out 1 Max %.
Notes:
1. Correct operation of the Loop Alarm depends upon reasonably accurate PID tuning.
2. The Loop Alarm is automatically disabled during Manual Control Mode and during
execution of the Pre-Tune Mode. Upon exit from Manual Mode or after completion
of the Pre-Tune routine, the Loop Alarm is automatically re-enabled.
6.3 Loop Alarm Time
When full ON/OFF control is selected and Loop Alarm is enabled, this parameter
determines the duration of the limit condition after which the Loop Alarm will be
activated. It may be adjusted within the range of 1 second to 99 minutes 59 seconds.
This parameter is omitted from the Tune Mode display sequence if ON/OFF control is
not selected or Loop Alarm is disabled. The default setting 99:59. Display code is LAti.
40
6.4 Logical Combination of Alarms
Two alarms may be combined logically to create an AND/OR situation.
They may be configured for Reverse-acting or Direct-acting. Either Output
2 or Output 3 may be assigned as Logical Outputs.
Example:
Logical OR of Alarm 1 with Alarm 2

The Hardware Definition Code and input jumper configuration may need to be changed. See

**
If Remote Setpoint Input has been selected in the Hardware Definition Code, this parameter will
appear in the normal Program Mode parameter sequence. The upper display shows a product code
which defines the input range. The factory setting depends on code selected, see Appendix B.
***
An Alarm Hysteresis output is made active only when both alarms become active; it subsequently
becomes inactive only when both alarms are inactive. Thus, the status of an Alarm Hysteresis output
only when one alarm is active depends upon the alarm status immediately prior to that alarm being
activated.
47
8.2 Hardware Definition Code
The Hardware Definition Code is used to represent the hardware installed (input type,
Output 1 type, Output 2 type and Output 3 type); this must be compatible with the
hardware actually installed. It can be accessed, with the instrument in Configuration
Mode (with a prompt inPS, etc. displayed), by simultaneously depressing the DOWN
and SCROLL keys. The displays will show "XXXX" (where X represents any number) in
the upper display and "dEFn" in the lower display, where:
the first (left-most) digit is input type:
1 = RTD/Linear mV
2 = Thermocouple
3 = Linear DC mA
4 = Linear DC V
the second digit is Output 1 type:
1 = Relay
2 = SSR
3 = DC 0-10 V
4 = DC 0-20 mA
5 = DC 0-5 V
7 = DC 4-20 mA
the third digit is Output 2 type:
O = Output 2 not installed
1 = Relay (control or alarm 2)
2 = SSR (control or alarm 2)
3 = DC 0-10 V (control only)
4 = DC 0-20 mA (control only)
5 = DC 0-5 V (control only)
7 = DC 4-20 mA (control only)
the fourth digit is Output 3 type:
O = Output 3 not installed
1 = Relay (alarm 1 only)
2 = SSR (alarm 1 only)
3 = DC 0-10 V (retransmit only)
4 = DC 0-20 mA (retransmit only)
5 = DC 0-5V (retransmit only)
7 = DC 4-20 mA (retransmit only)
48
The displayed code may be incremented/decremented using the UP/ DOWN keys as
required. The maximum setting available is 4777. For example, the code for a
thermocouple input, DC 4-20 mA Output 1 and relay Output 3 would be 2701. When
the code is first altered, the code display will flash, until the desired value is displayed
and confirmed by pressing the Auto/Manual key.
While the Hardware Definition Code is displayed, depressing the SCROLL
key will cause the display to change to:
none or
OPtn
r485 or
OPtn
duAL
OPtn
Where none indicates the absence of any option, r485 indicates the presence of the
communications option, and duAL indicates the presence of the dual setpoint option. If
selected, the plug-in digital input board used for selection of setpoint must be installed.
NOTE: The RS485 Serial Communications option and the plug-in Dual
Setpoint option are mutually exclusive.
Another depression of the SCROLL key will cause the appearance of the
Second Input Usage menu display, which may be one of the following:
none or
2inP
rSP1 or
2inP
rSP3
2inP
OR
rSP4
2inP or
rSP9
2inP or
duAL
2inP
Where nonE indicates Second Input not used, rSP1 indicates the use of the Second
Input as a linear DC mV Remote Setpoint, rSP3 indicates the use of the second input
as a linear DC mA Remote Setpoint, rSP4 indicates the use of the Second Input as
linear DC Volt Remote Setpoint, rSP9 indicates the use of the Second Input as
Potentiometer (up to 2K ohm) type Remote Setpoint, and duAL indicates Dual Setpoint
switching capabilities.
Selection of Dual Setpoint switching allows the digital input part of the Remote Setpoint
option to be used for dual setpoint switching, thus permitting the instrument to have
Dual Setpoint operation and RS485 Serial Communications (the normal setpoint
switching input and the RS485 Communications option are mutually exclusive.
49
NOTE:
It is essential that this code is changed whenever there is a change to the
instrument's hardware configuration (change of input/output type, alarm/
retransmit output added/removed etc.). The instrument's software
depends upon this code to ensure that the instrument operates correctly.
To exit from the Hardware Definition Code display, depress the DOWN and
SCROLL keys simultaneously.

SECTION 11: PRE-TUNE MODE
11.1 Pre-Tune Mode Description
The Pre-Tune Mode may be used to set the instrument's PID parameters to values
which are approximately correct, in order to provide a base from which the Auto Tune
Mode may optimize tuning.
To engage the Pre-Tune Mode, with the instrument in Control Mode, press the
SCROLL key until Mod is displayed. Press the DOWN key. Press the SCROLL key
until Pre is displayed. Press the UP key until the AT LED flashes. To disengage the
Pre-Tune Mode, press the DOWN key.
Note: Since the Pre-Tune Mode is a single-shot operation, it will automatically
disengage itself once the operation is complete, If the Enable Pre-Tune parameter
in the Tune Mode is enabled, then upon power interruption, the unit will first
engage the Pre-Tune Mode prior to engaging the Auto-Tune Mode when power is
restored.
Also note: The Pre-Tune Mode will not engage during setpoint ramping,
Additionally, if the process variable is within 5% of input span from the setpoint,
or if an incorrect key sequence is used, the Pre-Tune Mode will not be engaged.
To return to the Control Mode, press the SCROLL key until CtrL is displayed, then
press the DOWN key.
57
58
SECTION 12: AUTOTUNE MODE
12.1 AutoTune Mode and Description
The Auto-Tune Mode is used to optimize tuning while the instrument is operating.
To access the Auto-Tune Mode, with the instrument in Control Mode, enter the Setup
Mode. Press the SCROLL key until Auto is displayed. To engage Auto-Tune, press the
UP key. The AT LED will light red.
Note: If the Enable Pre-Tune parameter in the Tune Mode is enabled, then on
power-up, the unit will automatically engage the Pre-Tune Mode prior to engaging
the Auto-Tune Mode when power is restored.
To disengage the Auto-Tune Mode, access the Auto-Tune Mode. Press the DOWN
key. The AT LED will turn off.
To return to Control Mode, press the SCROLL key until CtrL is displayed, then press
the DOWN key.
12.2 How Auto-Tune Works
This instrument uses a pattern recognition algorithm, which monitors the process error
(deviation signal). Figure 12-1 shows a typical temperature application involving
process start up, a setpoint change and a load disturbance. The deviance signal is
shown shaded and overshoots have been exaggerated for clarity.
The auto-tuning algorithm observes one complete deviation oscillation before
calculating a set of PID values. Successive deviation oscillations cause values to be
recalculated so that the controller rapidly converges on optimal control.
When auto-tuning controllers are switched off, the final PID terms remain stored in the
controller's nonvolatile memory, and are used as starting values at the next switch on.
The stored values are not always valid, if for instance, the controller is brand new or the
application has changed. In these cases the user can utilize an extra facility on the
auto-tuning controllers called "Pre-Tune". Figure 12-2 shows how the "Pre-Tune"
facility artificially disturbs the start up pattern so that a first approximation of the PID
values can be made prior to the setpoint being reached.
59
New instruments supplied by the factory contain PID terms set at "DEFAULT" values
which have been found to give adequate and safe control over a wide range of
applications. In the "Pre-Tune" mode of operation, the "default" PID terms are loaded
and the controller demands 100% power until the process value has moved
approximately halfway to the setpoint. At that point, power is removed thereby
introducing a deviation oscillation. Once the oscillation peak has passed, the Pre-Tune
algorithm can calculate its first approximation to the optimum PID values. The power is
reapplied using new values. This technique limits possibility of setpoint overshoot when
the instrument is new or the application has been changed.

SECTION 13: RaPID FEATURE
13.1 RaPID Description
The RaPID (Response assisted PID) range of controllers have been designed with a
unique "fuzzy" logic algorithm which dramatically reduces overshoot and improves
settling times on start-up, setpoint changes and disturbances by 70%, without
complicating set-up and usage.
The fuzzy logic based algorithm enhances the traditional PID function, continuously
reblending the P, I and D control building blocks on line. Instead of learning from an
event and reacting after it has happened (which is how all self-tuning PID controllers
work, ) the RaPID controllers can react as an event occurs, thereby improving the
quality of control and speed of response in any application.
To access the RaPID Mode, access the Setup Mode. Press the SCROLL key until rAP
is displayed.
To engage the RaPID feature, press the UP key. The AT light will turn green. To
disengage the RaPID feature, access the RaPID Mode, and press the DOWN key. The
AT light will turn off.
To return to Control Mode, press the SCROLL key until CtrL is displayed, then press
the DOWN key.
For a detailed description of the RaPID feature, refer to Appendix C.
NOTE: If either Pb1 or Pb2 is zero, the RaPID feature cannot be engaged.

APPENDIX C: RaPID CONTROL FEATURE
The RaPID (Response - assisted PID) feature offers dramatic improvements in control quality
compared with conventional PID techniques. It responds much more effectively than PID
techniques to load conditions. With this feature, the instrument's response at start-up, during
setpoint changes and during disturbances shows considerably reduced overshoot and much
more shorter settling times (see below).
RaPID works best with well-tuned terms. It is therefore recommended, on newly installed
instruments, that the Pre-Tune facility is run before RAP[D is engaged.
Note: If Pre-Tune and RaPID are both engaged, Pre-Tune will run first. Once Pre-Tune (a
single shot process) is automatically disengaged, RaPID will operate automatically.
71
In conditions of frequent change in load characteristics, it is recommended that the Auto-Tune
facility is used.
Note: With Auto-Tune and RaPID engaged together, Auto-Tune is suspended until RaPID is
disengaged, whereupon Auto-Tune will operate automatically.
The responses to RaPID being engaged are:
