SECTION 1: INTRODUCTION
1.1 General
These instruments are microprocessor based process controllers. They can measure, display or
control process variables such as temperature, pressure, flow and level from a variety of inputs.
The operating voltage is either 100-240V at 50/60 Hz or 24V-48V AC/DC depending on the model
purchased. EEPROM technology protects against data or configuration loss during power outages.
Inputs are user configurable for connection to thermocouple and RTD probes, as well as linear
process signal types such as mVDC, VDC or mADC. Output options include relays, SSR drivers,
triacs or linear mV/voltage modules. These can be used for process control, valve control, alarms or
retransmission of the process variable or setpoint to external devices such as data recorders or
PLC’s. A Transmitter Power Supply option module can provide an unregulated 24V DC (22mA)
auxiliary output voltage for external signal transmitters.
Alarm indication is standard on all instruments. Alarms may be set as process high or low, deviation
(active above or below controller setpoint), band (active both above and below setpoint), or control
loop types. These alarms can be linked to any suitable output. Alarm status is indicated by LED’s or
the alarm status screen.
Controllers can be programmed for on-off, time proportioning, or current proportioning control
implementations, depending on the output modules fitted, and feature manual or automatic tuning of
the PID parameters. A secondary control output is available when additional output modules are
fitted. Optional analogue controller Remote Setpoint inputs are included in the range. Control
functions, alarm settings and other parameters are easily adjusted from the front keypad or via PC
based configuration software.

SECTION 3: PLUG-IN OPTIONS
3.1 Options Modules and Functions
A range of plug-in option modules is available to add additional input, output and communication
functions to the instruments in the range. These modules can be either pre-installed at the time of
manufacture, or retrofitted in the field.
The modules are installed between the instruments main circuit boards into the four option slots.
These are designated as Slots 1, 2, 3, A & B. Installation is detailed below.
Note:
Slot 1 modules cannot be fitted into Slot 2 or 3. Slot 2 & 3 modules cannot be fitted into Slot 1.
Some Slot 2 &3 modules should only be fitted into one of the two slots. This is detailed in the Option Module vs. Model Matrix below.

3.3 Preparing to Install or Remove Options Modules
CAUTION:
Before removing the instrument from it’s housing, ensure that all power has been
removed from the rear terminals.
1. Remove the instrument from its housing by gripping the side edges of the front panel (there is
a finger grip on each edge) and pull the instrument forwards. This will release the instrument
from the rear connectors in the housing and will give access to the PCBs.
2. Take note of the orientation of the instrument for subsequent replacement into the housing.
The positions of the main and option PCBs in the instrument are shown below.
3.4 Removing/Replacing Option Modules
With the instrument removed from its housing:
1. To remove or replace modules into Option Slots 1,A or B, it is necessary to gently separate
the
from the front moulding by lifting first the upper and then lower mounting struts as shown.
This frees the boards from the front. If only Option slots 2 or 3 are to be changed, this stage
is not required as these slots are accessible without separating the main boards from the
front.

SECTION 4: WIRING INSTRUCTIONS
Electrical noise is a phenomenon typical of industrial environments. As with any instrumentation,
these guidelines should be followed to minimize the effect of noise.
4.1 Installation Considerations
Ignition transformers, arc welders, mechanical contact relays and solenoids are all common sources
of electrical noise in an industrial environment and therefore the following guidelines MUST be
followed.
1. If the instrument is being installed in existing equipment, the wiring in the area should be
checked to ensure that good wiring practices have been followed.
2. Noise-generating devices such as those listed should be mounted in a separate enclosure. If
this is not possible, separate them from the instrument, by the largest distance possible.
3. If possible, eliminate mechanical contact relays and replace with solid-state relays. If a
mechanical relay being powered by an output of this instrument cannot be replaced, a solid state relay can be used to isolate the instrument.
4. A separate isolation transformer to feed only the instrumentation should be considered. The
transformer can isolate the instrument from noise found on the AC power input.
4.2 AC Power Wiring - Neutral (for 100 to 240V AC versions)
It is good practice to ensure that the AC neutral is at or near ground (earth) potential. A proper
neutral will help ensure maximum performance from the instrument.
4.3 Wire Isolation
Four voltage levels of input and output wiring may be used with the unit:
1. Analogue input or output (for example thermocouple, RTD, VDC, mVDC or mADC)
2. Relays & Triac outputs
3. SSR Driver outputs
4. AC power
10
CAUTION:
The only wires that should run together are those of the same category.
If any wires need to run parallel with any other lines, maintain a minimum space of 150mm between
them.
If wires MUST cross each other, ensure they do so at 90 degrees to minimise interference.
4.4 Use of Shielded Cable
All analogue signals must use shielded cable. This will help eliminate electrical noise induction on
the wires. Connection lead length must 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 at
the sensor, transmitter or transducer.
4.5 Noise Suppression at 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 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,
Resistance-Capacitance (RC) networks and/or Metal Oxide Varistors (MOV) may be added.
Inductive coils:- MOVs are recommended for transient suppression in inductive coils, connected in
parallel and as close as possible to the coil. Additional protection may be provided by adding an RC
network across the MOV.
Figure 7. Transient suppression with inductive coils
11
Contacts:- Arcing may occur across contacts when they open and close. This results in electrical
noise as well as damage to the contacts. Connecting a properly sized RC network can eliminate this
arc.
For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad capacitor (1000
volts) is recommended. For circuits from 3 to 5 amps, connect two of these in parallel.
Figure 8. Contact noise suppression
4.6 Sensor Placement (Thermocouple or RTD)
If the temperature probe is to be subjected to corrosive or abrasive conditions, it must be protected
by an appropriate thermowell. The probe must be positioned to reflect true process temperature:
1. In a liquid media - the most agitated area
2. In air - the best circulated area
CAUTION:
The placement of probes into pipe work some distance from the heating vessel leads to
transport delay, which results in poor control.
For a two wire RTD a wire link should be used in place of the third wire. Two wire RTDs must only
be used with lead lengths less than 3 metres. Use of three wire RTDs is strongly recommended.

4.7 Thermocouple Wire Identification Chart
The different thermocouple types are identified by their wires colour, and where possible, the outer
insulation as well. There are several standards in use throughout the world.
The table below shows the wire and sheath colours used for most common
thermocouple types. The format used in this table is:

4.9 Power Connections - Mains Powered Instruments
Mains powered instruments operate from a 100 to 240V (±10%) 50/60Hz supply. Power
consumption is 7.5VA. Connect the line voltage (live and neutral) as illustrated via a two-pole
isolating switch (preferably located near the equipment) and a 1amp anti-surge fuse. If the
instrument has relay outputs with contacts carrying mains voltage, it is recommended that the relay
contacts supply should be switched and fused in a similar manner, but should be separate from the
instruments mains supply.
WARNING:
CHECK THE INFORMATION LABEL ON THE CASE TO DETERMINE THE CORRECT VOLTAGE
BEFORE CONNECTING TO A LIVE SUPPLY.
