General Description
This series of meters accepts industrial sensors to allow various physical measurements to
be made, such a weight, temperature, pressure, humidity etc. Different models are available
for different sensor types.
The main function of this series is to give a numeric readout of the variable being monitored.
Most models include an excitation power output, to power the sensor directly.
Various optional output modules are also available to give alarm relay outputs, analogue
output or digital communications, or any combination of these options.
Meters are programmed using front panel pushbuttons. The buttons may be locked with a
rear switch.
Meters have two power supply options : 100-240 VAC or 11-30VDC
These meters are designed to mount into a protective enclosure which will protect users from
contact with power and signal wiring.
These units must be installed fully assembled, and must be installed according to local electrical
installation rules. When properly installed, they provide ingress protection to IP65 / NMA4X
from the front

DIN Rail Mounting option
This Series is ideal if you need high precision signal conditioning. Sometimes, it is not
necessary to have front panel indication, so in such cases, we offer a DIN rail mounting option,
which allows the meter to be installed within a control panel.
Detachable connectors add to the simplicity of installation, and of course the setup method is
identical to the panel mounting version, so you don’t need to learn a new method.
The display remains active, so you can see at a glance the status of your signals, and
programming is simple, using the 4 buttons.
Output functions include isolated 16 bit 4-20mA, 0-10V, -10 to +10V, RS232, RS485 and up
to 4 alarms with a wide choice of alarm functions.
Install the meters in a suitable protective electrical control enclosure according to local wiring
regulations. See specifications for maximum allowable temperature in enclosure. Allow
adequate air circulation.
Securing into the panel
Use standard top-Hat DIN rail 35 mm x 7.5 mm (EN 50022, BS 5584, DIN 46277-3)
Ventilation
There should be sufficient ventilation in the enclosure to ensure that the meter’s case is
always kept to less than 60C.

Wiring Advice
This meter uses detachable screw terminal connectors. Refer to the wiring diagram on the
following page for the correct positioning of each wire.
The conductors you use must be suitable for the meter’s temperature, current and voltage
rating, which is broadly described as follows:-
Cable Temperature Rating
All cables must be rated for operation up to 90C continuous.
Cable gauge and screw tightness
The connectors on this instrument can accept conductors up to 16 gauge AWG / 1.5mm2
c.s.a. The minimum cross sectional area shall be 22 gauge AWG / 0.5mm2 . Tighten screw
terminals to 7.0 lb/in torque / 0.8 Nm torque.
Cable insulation voltage rating
Cables shall have an insulation voltage rating of at least 380V continuous.

No bare wires exposed
125mm behind panel
We recommend multi-strand wire, because it withstands vibration better than single strand
cable. Pull the wire firmly after you make the connection to confirm it is tight.
Use screened cable for all signal and control wiring and connect the screen to earth at the
destination end only. Route signal cabling away from power cabling and relay switching
cabling, to avoid electrical noise interference.

Installation hints for best performance
This section offers several suggestions which will help you get the best performance from
your measurement system.
Some sensors generate comparitively small signals which can easily be corrupted by the
potentially high level of electrical noise which can be created by electrical machinery such as
motors, welding systems, discharge lighting, AC power inverters and solenoids. These steps
will ensure you get the best possible performance from your system.
If you are using multi-pair twisted cable, each pair should be dedicated to a single
display as shown opposite, for maximum noise immunity.This will ensure that any
electrical noise induced in the cable is properly cancelled. Mixing destinations
carelessly amongst the twisted pairs can actually worsen noise performance.
3.
The cable should be routed away from noisy wiring and devices such as power
feeds from inverters, discharge-lighting cables, welder cabling etc, and should
preferrably be routed in a dedicated low voltage signalling/instrumentation conduit
or cable tray.
4.
Screened cable should be earthed at the display end only.
5.
All wires and screens coming out of the screened cable should be kept as short
as possible to minimise pickup of noise.
6.
If you are using barriers, you should earth your screen as shown below, paying
particular care that you do not earth both ends of any run of of cable.
Hazardous Area

2.
Logic Input
Use good quality screened signal cable, with twisted pairs. Belden 8777NH,
Belden 9503 and AlphaWire 6010C are good choices, available from many
electrical distributors.

Sensor 1
Do NOT use a wire from one pair for signal positive and a wire from another pair for signal negative, as this will prevent the
twisted cables form cancelling any induced electrical noise, and can couple noise from one channel to another.
When using multi-core screened cable to connect several displays to several sensors, please be sure to use one twisted pair for
each display and sensor.

Application notes for Production rate Mode
1. Choose an averaging time, in seconds, you want to use for computing your production
rate.
For example if you want to average over 45 minutes, your averaging time will be 2700
seconds.
We need to calculate an update time for your display, we will have up to 200 samples available in your averaging period.
Update time = 2700/200 = 13.5
Round this up to the nearest whole number.
This is set in the variable bin.t = 14
Set bin.cnt = 200
This means that your display will update every 14 seconds in this case.
NB If your averaging time is less than 3 minutes, please use the formula
Update time = averaging time/20 , round up to nearest whole number = bin.t
Set bin.cnt = 20
2. We now need to set a scale factor so that your display reads correctly in items per hour,
per minute or per second.
The scale factor settings will be....
For items per second = SCALE = 1/bin.t
For items per minute = SCALE = 60/bin.t
For items per hour
= SCALE = 3600/bin.t
For items per shift
= SCALE = 28800/bin.t
For items per day
= SCALE = 86400/bin.t

Quadrature mode - application notes
In a quadrature sensor, the two incoming pulses overlap. Pulses to input 1 will arrive before
or after pulses to input 2, depending on the direction of movement. This is achieved by
staggering the trigger zones for sensor A and B. They must overlap, so that one will lead the
other in one direction, and vice-versa. Trigger zones on large rotating wheels can be bolt
heads or holes. In small engular encoders, the trigger zones are normally etched into a thin
disc or are photographically produced to make light and dark areas.

Trigger zones
Sensor A triggers before sensor B
Sensor B triggers before sensor A
In the simplified arrangement shown above, we get 4 pulses per revolution, because we
have 4 pairs of triggers. The angular resolution we get with this arrangement is 90 degrees.
Some sensors have 1024 pulses per revoltution, giving 0.35 degree resolution, but there
are many different arrangements available. Our scheme above would be typical in cable
laying applications, where it is more important to count revolutions of the drum than to know
its absolute angle. The trigger zones can also be arranged in a straight line instead of
around a circumference, to create a sensor for linear displacement.
Please be sure to check that the sensor’s maximum output frequency is kept to less than
10 000 pulses per second.

Logic input connections and front buttons
The previous page explained how to select the functions of the 3 logic inputs. You can
connect remote contact closures or open NPN collectors to activate these logic inputs.
The logic input provides a 5V DC signal. When you connect this to common, a current of
1mA will flow. Because this is a small signal, we recommend you use switches with gold
plated contacts, or self cleaning contacts, for best long term reliability.
The logic inputs are not galvanically isolated from the input signal.
The logic inputs are only activated when the lockout switch is ON

Signal Filtering / Averaging
You can adjust the filtering time constant to reduce the effect of noise or instability on your
input signal.
A larger FIL value will give a more stable display, but the response to signal changes will be
slower.
Because your output options, such as analogue output, alarm relays and serial output are all
derived from the displayed value, they will respond at the same rate as the filtered display.

See also Filter Jump setting in the Advanced Menu, if your signal is particularly noisy and
you cannot get sufficient smoothing with this filter.
32
Filter Jump value
See the Easy/Advanced mode selection page near the beginning of this manual, and
choose advanced mode.
The Filter Jump value allows you to decide how the display will respond to a process step
change. It does this by overriding the filtering, if the input signal moves by more than a
chosen amount in one conversion. The Filter Jump default value is 10%.
This means that for noise amplitude which has a peak value of less than 10% of the input
range, filtering will be applied. Any signal movement greater than 10% of the input range will
cause the display to jump immediately to that value, without filtering. After that jump, normal
filtering will be re-applied, provided signal movement thereafter is less than 10% per conversion.
Guidance:
For noisy systems, increase the Filter Jump value up to a maximum of 99. Choose a value
which gives a good compromise between filtering and response speed.
For reasonably clean signals, a Filter Jump value of around 10 or less will give a good
compromise between filtering and response speed to step change inputs.

Multi-Program Memory option (Rate mode only)
The three contact closure inputs on the rear of the meter may be used to call up between 1
to 7 additional meter setup memories (pages), if the MEM option has been installed. This
allows you to save up to 8 complete sets of independent calibrations, alarm settings, analogue output settings and serial comms settings.
First decide how many memory pages you want, as this will determine how many logic
inputs you will need to use for the addressing. Logic inputs not required for Page Addressing can be used for other functions such as Tare, Reset, Display Hold, Peak/Valley display.
If you have used all 3 logic inputs for Page Addressing, you can still use the meter’s front
panel buttons to perform Tare, Reset and peak/Valley view.
See “Contact Closure Input Functions” page for CC.1, CC.2, CC.3 and COP settings

BCD switch
Perform the settings you require, according to the pages in this manual. Do this for all page
addresses required. Then put the lockout switch in its ON position. Now, if you select a
page address, the meter will briefly confirm the chosen page address on screen, and will
then function according to the settings you programmed for that address.
Suitable BCD coded switches are available from many electrical supply stores.
For example consider Kraus & Naimer part A540-600 E24 or Apem part number IRBC10N1248 or London
Electronics part number SW2P-8W-BCD, which also provides separate 2 pole 8 way signal selection
function.

Error codes and fault finding
--Ur---Or--
1. Under Range. The meter is being asked to display a value which is more
negative than its limit of -199999
2. Over Range. The meter is being asked to display a value which is higher
than its limit of 999999
These fault codes could be displayed because the signal scale factor has
been set too large or because the input frequency is too high.
3. Display is reading much higher than you expect and may also be erratic.
This could be caused by contact bounce if you are using a contact closure
input - be sure that the contact debounce is enabled
dbnc.on
4. Total is not saved on power-down in a DC powered totaliser.
This could be caused by converting a DC powered INT2-P, INT2-L, INT2-S
etc to an INT2-C. If you have converted one of these models to INT2-C,
simply by changing the input board, you will find that total is not stored at
power-down. You will need to fit a power-down control module, part number
9122-0401 to the display control board.

How to install option boards
!
Where the product is intended for “UL” installations
removal or addition of option boards is not permitted.
Warning:
Disconnect
power before you expose
the rear of the meter
If you want to open your meter to install or modify option boards, follow these steps...
1)
Switch off power to the meter and unplug all connectors.
2)
Unclip the front bezel. This is easier if you squeeze the top and bottom of
the case, near the front.
3)
Remove the small screws shown in the diagram. If the meter doesn’t yet
have an output option board, the top screw may not yet be fitted.
4)
Slide the electronic boards out throught the front of the case. You can easily
separate the upper option board from the
main board. We strongly suggest that you
use anti-static precautions to prevent
damage to the semiconductors.
The board assemblies will look something like this...
Real Time
Clock option
Main board
Input board
Upper option board
RS232, RS422
RS485
plug-in option
Alarm relays.
Depending on
the option, there
will be none, 2 or
4 relays fitted.
Analogue
output
plug-in option
The analogue output and RS232 or RS422 plug-in option boards are fixed to the upper option
board with white plastic pillars. You must apply a firm force when fitting or removing these
options.
Always be careful to connect the pins to sockets accurately. When reassembling, make sure
option boards are firmly fixed to the upper option board. When the boards are replaced in the
case, secure them again with the two small black screws.
