How to use this manual This manual is structured to give easy access to the information required for all aspects of the installation and use and of the products: Section 1: Introduction - A brief description of the product range. Section 2: Installation - Unpacking, installing and panel mounting instructions. Section 3: Plug-in Options - Installation of the plug-in option modules.
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.
SECTION 2: INSTALLATION 2.1 Unpacking 1. Remove the product from its packing. Retain the packing for future use, in case it is necessary to transport the instrument to a different site or to return it to the supplier for repair/testing. 2. The instrument is supplied with a panel gasket and push fit fixing strap. A single sheet concise manual is also supplied in one or more languages. Examine the delivered items for damage or defects. If any are found, contact your supplier immediately. 2.
2.3 Panel Cut-outs The mounting panel must be rigid and may be up to 6.0mm (0.25 inches) thick. The cut-outs required for the instruments are shown below. 90mm +0.5 –0.0 (3.62” +.020 -.000) 90mm +0.5 –0.0 (3.62” +.020 -.000) Figure 2. Panel cut-out size 2.4 Panel-Mounting CAUTION: Ensure the inside of the panel is with the instruments operating temperature and that there is adequate air flow to prevent overheating.
Once the instrument is installed in its mounting panel, it may be subsequently removed from it’s housing, if necessary, as described in the Fitting and Removing Option Modules section. Instruments may be mounted side-by-side in a multiple installation, but instrument to panel moisture and dust sealing will be compromised. The cut-out width (for n instruments) is shown below. 1 /4 - DIN Instruments: (96n - 4) mm or (3.78n - 0.
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.
Table 1.
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.
CAUTION: Take care not to put undue stress on the ribbon cable attaching the display and CPU boards. 2. Remove or fit the modules into the Option slots as required. The location of the connectors is shown below. Tongues on each option module locate into a slots cut into the main boards, opposite each of the connectors. Option Slot B Connectors PL2A, PL2B & PL2C Option Slot 2 Connector PL4A Option Slot 1 Connectors PL7 & PL8 Option Slot A Connectors PL5 & PL6 Option Slot 3 Connectors PL4B 1 Figure 6.
3.5 Replacing the Instrument in its Housing With the required option modules correctly located into their respective positions the instrument can be replaced into its housing as follows: 1. If required, move the CPU and PSU boards back together, taking care to locate the option module tongues into the slots in the board opposite. Hold the main boards together while relocating them back into the mounting struts on the front panel. 2.
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.
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.
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.
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 thermocouple types. The format used in this table is: + Wire - Wire Sheath common Table 2.
WARNING: CHECK THE INFORMATION LABEL ON THE CASE TO DETERMINE THE CORRECT VOLTAGE BEFORE CONNECTING TO A LIVE SUPPLY. Note: The wiring diagram below shows all possible combinations. The actual connections required depend upon the features available on the model and the modules and options fitted. 1 Figure 9.
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.
WARNING: CHECK THE INFORMATION LABEL ON THE CASE TO DETERMINE THE CORRECT VOLTAGE BEFORE CONNECTING TO A LIVE SUPPLY. 4.11 Universal Input Connections - Thermocouple (T/C) Use only the correct thermocouple wire or compensating cable from the probe to the instrument terminals avoiding joints in the cable if possible. Failure to use the correct wire type will lead to inaccurate readings. Ensure correct polarity of the wires by cross-referencing the colours with a thermocouple reference table.

SECTION 9: MANUALLY TUNING CONTROLLERS 9.1 Single Control Tuning (PID with Primary Output only) This simple technique balances the need to reach setpoint quickly, with the wish to limit setpoint overshoot at start-up or during process changes. It determines values for the Primary Proportional Band (Pb_P), Integral Time Constant (ArSt) and Derivative Time Constant (RAte) that allow the PID control algorithm to give acceptable results in most applications that use a single control device.
9.2 Dual Control Tuning (PID with Primary and Secondary Outputs) This simple tuning technique balances the need to reach setpoint quickly, with the wish to limit setpoint overshoot at start-up and during process changes. It determines values for the Primary Proportional Band (Pb_P), Secondary Proportional Band (Pb_S), Integral Time Constant (ArSt) and Derivative Time Constant (RAte) that allow the PID control algorithm to give acceptable results in most applications that use dual control (e.g. Heat & Cool).
6. Follow the instructions in the diagram below. At each stage, allow sufficient settling time before moving on to the next stage. Process Variable START Apply Power to the load. Does the Time Tb Yes PV continuously Oscillate? No Note the time Are the interval Ta Oscillations Yes decaying to zero? Set Pb_P = 0.8% Note the period of the decaying Set ArSt = Ta No oscillations (Tb) Multiply Pb_P setting by 1.5 Multiply Pb_P setting by 1.
9.4 Manually Fine Tuning A separate cycle time adjustment parameter is provided for each time proportioning control output. Note: Adjusting the cycle time affects the controllers operation; a shorter cycle time gives more accurate control but electromechanical components such as relays have a reduced life span. 1. Increase the width of the proportional band if the process overshoots or oscillates excessively. 2.
SECTION 10: MODBUS SERIAL COMMUNICATIONS All models support the Modbus RTU communication protocol. Some models also support an ASCII communication protocol. Where both Modbus and ASCII are supported, the protocol to be used is selected from Configuration Mode. The RS485 Communications Module must be fitted into Option Slot A in order to use serial communications. Refer to the relevant Model Group Section for the ASCII and Modbus Application Layer (parameter address/ident information).
10.2 Link Layer A Query (or command) is transmitted from the Modbus Master to the Modbus Slave. The slave instrument assembles the reply to the master. All of the instruments covered by this manual are slave devices, and cannot act as a Modbus Master. MODBUS SLAVE MASTER INSTRUMENT QUERY RESPONSE Modbus Link Layer A message for either a QUERY or RESPONSE is made up of an inter-message gap followed by a sequence of data characters. The inter-message gap is at least 3.5 data character times.
10.3 Device Addressing The instrument is assigned a unique device address by the user in the range 1 (default) to 255 using the Addr parameter in Configuration Mode. This address is used to recognise Modbus Queries intended for this instrument. The instrument does not respond to Modbus Queries that do not match the address that has been assigned to it. The instrument will also accept global Queries using device address 0 no matter what device address is assigned.
Read Coil/Input Status (Function 01 / 02) Reads the content of instruments output/input status bits at the specified bit address. Table 17. Read Coil/Input Status (Modbus Function 01/02) QUERY Address of 1st Bit Function 01 / 02 HI Function Number of Bits LO HI LO RESPONSE Number of Bytes First 8 bits 2nd 8 Bits 01 / 02 In the response the “Number of Bytes” indicates the number of data bytes read from the instrument. E.g. if 16 bits of data are returned then the count will be 2.
Force Single Coil (Function 05) Writes a single binary value to the Specified Instrument Bit address. Table 19. Force Single Coil (Modbus Function 05) QUERY Address of Bit Function 05 HI FF/00 RESPONSE Address of Bit Function 05 LO State to write HI LO 00 State written FF/00 00 The address specifies the address of the bit to be written to. The State to write is FF when the bit is to be SET and 00 if the bit is to be RESET. Note: The Response normally returns the same data as the Query.
Note: The Response normally returns the same data as the Query. Pre-Set Multiple Registers (Function 10 Hex) Writes a consecutive word (two-byte) value to the specified address range. Table 22.
Note: In the case of multiple exception codes for a single QUERY the Exception code returned is the one corresponding to the first parameter in error.
SECTION 11: ASCII COMMUNICATIONS This is simple ASCII protocol provides backwards compatibility with some older products. ASCII is not available in all models in the range. The Modbus protocol is recommended for future use. Refer to the relevant Model Group Section for the ASCII and Modbus Application Layer (parameter address/ident information). 11.
Table 24. ASCII Parameter Key {S} is the Start of Message character L (Hex 4C) or R (Hex 52). L is used for Controllers; R is used for Profilers. {N} is the slave device address (in the range 1 - 99); addresses 1 - 9 may be represented by a single digit (e.g. 7) or in two-digit form, the first digit being zero (e.g. 07). {P} {C} is a character which identifies the parameter to be interrogated/modified.
Type 2 Message L {N} {P} {C} * or R {N} {P} {C} * This type of message is used by the master device, to interrogate or modify a parameter in the addressed slave device.
Type 4 Message L {N} {P} I * or R {N} {P} I * This type of message is sent by the master device to the addressed slave device, following a successful Type 3 transaction with the same slave device. Provided that the {DATA} content and the parameter specified in the preceding Type 3 message are still valid, the slave device will then set the parameter to the desired value and will reply in the form: L {N} {P} {DATA} A * where {DATA} is the new value of the parameter.
SECTION 12: CALIBRATION MODE WARNING: CALIBRATION IS ONLY REQUIRED FOR INSTRUMENTS IN WHICH CALIBRATION ERRORS HAVE BEEN ENCOUNTERED. REFER TO CALIBRATION CHECK BELOW. CAUTION: Calibration must be performed by personnel who are technically competent and authorised to do so. Calibration is carried out during manufacture and is not normally required again during the lifetime of an instrument. 12.
12.3 Recalibration Procedure Recalibration is carried out in five phases as shown in the table below, each phase corresponds to an input range of the instrument. CAUTION: The 50mV phase MUST be calibrated before the thermocouple range. Table 26.

Integral Refer to Automatic Reset.
Logical Combination of Alarms Type: General Definition Two alarms may be combined logically to create an AND/OR situation. Any suitable output may be assigned as a Logical Alarm Output, configured for Reverse-acting or Direct action. Also refer to Alarm Operation Table 27.
Loop Alarm Time Type: Controller Parameter When 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 Set-up mode display sequence if On-Off control is not selected or loop alarm is disabled. Display code = LAti, Default setting is 99:59. Also refer to Loop Alarm Enable.
Also refer to Cascade Control, Retransmit Output, Remote Setpoint, Serial Communications, Setpoint Modulating Valve Type: VMD Controller Definition A valve that can be positioned anywhere between fully closed and fully open by means of an incorporated motor. A typical application would be controlling temperature in a furnace heated by gas burners. Some modulating valve motors require linear (mA or VDC) signals to position the valve. These require standard Process Controllers (using PI control).
Overlap/Deadband Type: Controller Parameter Defines the portion of the primary and secondary proportional bands (Pb_P + Pb_S) over which both outputs are active (Overlap), or neither is active (Deadband). It is adjustable in the range -20% to +20% of the two proportional bands added together. Positive values = Overlap, negative values = Deadband. This parameter is not applicable if the primary output is set for On-Off control or there is no Secondary Output.
PI Control Type: Controller Definition Proportional and Integral (PI) Control is used to control Modulating Valves. It is similar to PID Control, but without Derivative (Rate) action that causes excessive valve movement. Also refer to Modulating Valve, PID Control, Rate, Tuning and Valve Motor Drive Control. PID Control Type: Controller Definition Proportional Integral and Derivative control maintains accurate and stable levels in a process (e.g. temperature control).
Pre-Tune Type: Controller Definition 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. During Pre-Tune, the controller outputs full Primary Power until the process value has moved approximately halfway to the setpoint. At that point, power is removed (or outputs full Secondary Power for Dual Control), thereby introducing an oscillation.
Primary Proportional Band Type: Controller Tuning Parameter The portion of the input span over which the Primary Output power level is proportional to the process variable value. It may be adjusted in the range 0.0% (ON/OFF) to 999.9%. Applicable if Control Type is Single or Dual. For dual control a Secondary Proportional band is used for the second output. The Control Action can be Direct or Reverse acting. The Display value = Pb_P, default value = 5.0%.
Rate (Derivative) Type: Controller Tuning Parameter Rate is adjustable in the range 0 seconds (OFF) to 99 minutes 59 seconds. It defines how the control action responds to the rate of change in the process variable. This parameter should not be used in modulating value applications as it can cause premature wear due to constant small adjustments to the valve position. The Rate parameter is not available if primary control output is set to On-Off.
Display value = rSPo, default value = 0. Also refer to Remote Setpoint, Scale Range Upper Limit and Scale Range Lower Limit. Retransmit Output Type: General Definition A linear DC voltage or mA output signal, proportional to the Process Variable or Setpoint, for use by slave controllers or external devices, such as a Data Recorder or PLC. The output can be scaled to transmit any portion of the input or setpoint span. Also refer to Input Span, Master & Slave, Process Variable and Setpoint.
Also refer to Process Variable, Retransmit Output, Retransmit Output 3 Scale Minimum, Scale Range Upper Limit and Setpoint. Retransmit Output 3 Scale Minimum Type: General Parameter Defines the value of the process variable, or setpoint, at which Retransmit Output 3 will be at its minimum value. It is similar to Retransmit Output 1 Scale Minimum. Display code = ro3L, default value = Scale Range Lower Limit.
Self-Tune Type: Controller Tuning Definition Self-Tune continuously optimises tuning while a controller is operating. It uses a pattern recognition algorithm, which monitors the process error (deviation). The diagram shows a typical application involving a process start up, setpoint change and load disturbance. Temperature Setpoint 2 Load Disturbance Setpoint 1 Setpoint Change Time Figure 39. Self-Tune Operation The deviation signal is shown shaded and overshoots have been exaggerated for clarity.
Set Valve Opened Position Type: VMD Controller Parameter When Valve Position Indication is to be used on Valve Motor Controllers, this parameter defines the input value that will be measured by the Auxiliary Input, when the valve is fully opened. The valve must driven to its “Open” end stop before setting this parameter. It must not be used to limit valve movement, separate Valve Close and Open Limit parameters are available for this purpose.
setpoint at power up, or when switching back to automatic mode from manual control, will be equal to the current process variable value. The actual setpoint will rise/fall at the ramp rate set, until it reaches the target setpoint value. Setpoint ramping is used to protect the process from sudden changes in the setpoint, which would result in a rapid rise in the process variable. Display code = rP, default setting = OFF (blank). Also refer to Manual Mode, Setpoint, Setpoint Ramp Enable and Setpoint Select.
Display code = tArE, default setting = diSA (disabled). Also refer to Indicator, Process Variable, and Offset. Three Point Stepping Control Refer to Valve Motor Control. Type: VMD Controller Definition Time Proportioning Control Type: Controller Definition Time proportioning control is accomplished by cycling the output on and off, during the prescribed cycle time, whenever the process variable is within the proportional band. The control algorithm determines the ratio of time (on vs.
Valve Motor Drive Control Type: VMD Controller Definition Valve Motor Drive Controllers are designed to control Modulating Valves using a special “Open Loop” Valve Motor Drive (VMD) PI control algorithm. Output signals are provided to move the valve further open, or further closed when the process is higher or lower than the desired setpoint. When on setpoint, no output is required to maintain control unless load conditions change. This known as Three-Point Stepping control.
