1 Introduction
This product is a 1/4 DIN size (96 x 96mm front) microprocessor based graphical process controller, featuring
a 160 x 80 pixel, monochrome LCD with a dual color
(red/green) backlight. It can control process variables
from a variety of sources such as temperature, pressure, flow and level.
Inputs are user configurable for thermocouple and RTD
probes, as well as linear process signal types such as
mVDC, VDC or mADC. Multipoint scaling can compensate for non-linear signals. Output options include
relays, SSR drivers, triacs or linear mV/voltage modules. These can be used for process control, alarms
or retransmission of the process variable or setpoint
to external devices. Transmitter Power Supply options
can provide an unregulated 24V DC (22mA) auxiliary
output voltage, or a 0 to 10VDC stabilised excitation for
external signal transmitters.
The operating voltage is either 100-240V at 50/60 Hz or
24V-48V AC/DC depending on the model purchased.
Optional features include a USB interface, RS485 or
Ethernet communications, profile controlling and data
recording. Non-volatile memory protects against data
or configuration loss during power outages. If the unit
is left un-powered, a lithium battery powers the data
recorder’s real-time clock for a minimum of one year.
Alarm indication is standard on all instruments; up
to five alarms can be defined. Alarms may be set as
process high or low, deviation (active above or below
controller setpoint), band (active both above and below
setpoint), rate of input change, control loop or signal
break types. Alarm status can be indicated by lighting
an LED, changing the display backlight color or viewing
the alarm status screen. These alarms can be linked to
any suitable output.
The USB Interface option allows uploading or downloading instrument configuration settings to/from a
USB memory stick, for easy configuration of multiple
instruments or transfer to/from the PC configuration
software. If the Data Recorder of Profiler options are
fitted, recordings and profile information can also be
transferred via the memory stick.
The controller 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 analog
Remote Setpoint inputs can be included. Configuration
of the major settings is made easy by a Setup Wizard
that runs automatically at first ever power-up or whenever option modules have been changed. Access to
the full range of parameters is via a simple menu driven
front panel interface, or the PC based configuration
software.
The Data Recorder option allows the user to make recordings of the process over time. Recordings can be
transferred to a memory stick using the USB Port or
downloaded using one of the communications options.
The Profiler option allows the user to predefine up 255
segments, shared amongst up to 64 Setpoint Profiles.
These control the setpoint level over time, increasing,
decreasing or holding its value as required. When combined with the real-time clock of the Data Recorder option, the profiling capabilities are expanded to allow
automatic program start at a defined time and day.
2 Installation
Unpacking
Installation
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.
Installation should be only performed by technically competent personnel. It is the responsibility of the installing engineer to ensure that
the configuration is safe. Local Regulations
regarding electrical installation & safety must
be observed (e.g. US National Electrical Code
(NEC) or Canadian Electrical Code).
2. The instrument is supplied with a panel gasket and
push-fit fixing strap. Concise manual(s) are supplied
with the instrument, in one or more languages. Examine the delivered items for damage or defects. If
any are found, contact your supplier immediately.
1
Instruments may be mounted side-by-side in a multiple installation, but instrument to panel moisture and
dust sealing will be compromised. Allow a 20mm gap
above, below and behind the instrument for ventilation.
The cut-out width (for n instruments) is:
(96n - 4) mm or (3.78n - 0.16) inches
If panel sealing must be maintained, mount each instrument into an individual cut-out with 6mm or more
clearance between the edges of the holes.
Note: The mounting clamp tongues may engage the
ratchets either on the sides or the top/bottom faces of
the Instrument housing. When installing several Instruments side-by-side in one cut-out, use the ratchets on
the top/bottom faces.
Figure 1. Main dimensions
Ensure the inside of the panel remains within
the instrument operating temperature and that
there is adequate airflow to prevent overheating.
Do not remove the panel gasket, as this may
result in inadequate clamping and sealing of
the instrument to the panel.
Once the instrument is installed in its mounting panel,
it may be subsequently removed from its housing, if
necessary, as described in the Fitting and Removing
Option Modules section.

Panel-Mounting
Cleaning
The mounting panel must be rigid and may be up to
6.0mm (0.25 inches) thick. The cut-out size is:
Clean the front panel by washing with warm soapy
water and dry immediately If the USB option is fitted,
close the USB port cover before cleaning.

Preparing to Install or Remove Options
Modules
slots cut into the main boards, opposite each of the
connectors. Hold the Power and Input boards together and relocate them back on their mounting struts.
4. Remove or replace the Slot C and 4 modules as required.
Before removing the instrument from its housing, ensure that all power has been removed from the rear
terminals. Any repair or modification done on the controller is subject to the requirements of the jurisdiction.
The jurisdiction can be defined as plant safety or chief
engineer, city, county or state electrical inspector, etc.
Modules / boards should only be replaced by a trained
and qualified technician per the latest edition of the
NEC (National Electric Code).
5. Push the boards forward to ensure correct connection to the front Display/CPU board.
Check for correct orientation of the modules
and that all pins are located correctly.
Replacing the Instrument in its Housing
1. Remove the instrument from its housing by gripping
the 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 boards.
Before replacing the instrument in its housing,
ensure that all power has been removed from
the rear terminals.
2. Take note of the orientation of the instrument for subsequent replacement into the housing. The positions
of the boards in the instrument are shown above.
With the required option modules correctly located
into their respective positions the instrument can be
replaced into its housing as follows:

Profiler Enabling
5. If the input board has to be replaced, a full recalibration must be carried out before the instrument is
used. Refer to the calibration section of this manual
for instructions.
If you purchased a controller with the Profiler option
installed, these features will be enabled during manufacture.
Controllers supplied without the Profiler option installed can be upgraded in the field by purchasing a
licence code number from your supplier. A unique code
must be purchased to enable profiling on each controller that requires it.
Replacement of boards must be carried out by
a trained technician.
If the Power Supply board does not match the labelling, users may apply incorrect voltage resulting in irreparable damage.

4 Electrical Instructions
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.
Installation should be only performed by technically competent personnel. It is the responsibility of the installing engineer to ensure that
the configuration is safe. Local Regulations
regarding electrical installation & safety must
be observed (e.g. US National Electrical Code
(NEC) or Canadian Electrical Code).
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.
Installation Considerations
Wire Isolation
Ignition transformers, arc welders, motor drives, mechanical contact relays and solenoids are examples of
devices that generate electrical noise in typical industrial environments. The following guidelines MUST be
followed to minimise their effects.
Four voltage levels of input and output wiring may be
used with the unit:
1. Analog input or output (for example thermocouple,
RTD, VDC, mVDC or mADC)
2. Relays & Triac outputs
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.
3. SSR Driver outputs
4. AC power
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.
The only wires that should run together are
those of the same category.
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.
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.
5
Use of Shielded Cable
All analog 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.
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.
Figure 6. Contact noise suppression
Figure 6.
Contact noise suppression
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:
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.
1. In a liquid media - the most agitated area
2. In air - the best circulated area
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 meters. Use of three wire RTDs
is strongly recommended.
Figure 5. Transient suppression with inductive coils
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.

5 Powering Up
the LED indicators are lit. At the first power up from
new, or if the option modules are changed, the Setup
Wizard will run, indicating that configuration is required
(refer to the Setup Wizard section of this manual). At all
other times, the instrument returns to Operation Mode
once the self-test procedure is complete.
Ensure safe wiring practices have been followed. When powering up for the first time,
disconnect the output connections.
The instrument must be powered from a supply according to the wiring label on the side of the unit. The
supply will be either 100 to 240V AC, or 24/48V AC/DC
powered. Check carefully the supply voltage and connections before applying power.
Front Panel Overview
The illustration below shows the instrument front panel.
A USB socket fitted to USB and Data Recorder versions, to the right of the keypad.
Powering Up Procedure
Clean the front panel by washing with warm soapy
water and dry immediately If the USB option is fitted,
close the USB port cover before cleaning.
At power up, a self-test procedure is automatically
started, during which a splash screen is displayed and

7 Configuration and Use
Operation Mode
Base, Trend & Profile Operating Screens
This is the mode used during normal operation of the
instrument. It can be accessed from the Main Menu,
and is the usual mode entered at power-up. The available displays are dependent upon the features and options fitted and the way in which it has been configured.
The Base screen is the usual screen displayed during
operation. It provides “at a glance” information about
the process. The Profile Operating screen shows similar information when using profiles. Trend View is a
graphical representation of recent process conditions.
Its scale adjusts automatically for the best resolution
for the visible data.
DURING NORMAL USE, THE USER MUST NOT
REMOVE THE CONTROLLER FROM ITS HOUSING OR HAVE UNRESTRICTED ACCESS TO THE
REAR TERMINALS, AS THIS WOULD PROVIDE
POTENTIAL CONTACT WITH HAZARDOUS LIVE
PARTS.
Note: Trend data is not retained at power down or if the
Sample Interval is changed.
Set all Configuration parameters as required
before starting normal operations. It is the responsibility of the installing engineer to ensure
that the configuration is safe for the intended
application.

8 The USB Interface
The features covered in this section of the manual are
available on models fitted with the optional USB Interface or the Data Recorder (which includes the USB Interface).
If the file or folder named already exists, data
will be overwritten
Using the USB Port
The first recorder log file written is named 000001-1.
csv and placed in the new Recorder sub-folder. Stopping/starting a recording does not create a new file, but
each time the parameters being recorded are changed
a new file is created (e.g. 000002-1.csv then 000003-1.
csv etc). If any of these files would exceed the maximum spread sheet size of 65500 data lines, a new file
is created with the last digit incremented by 1 (e.g.
000001-2.csv then 000001-3.csv).
The USB Interface option allows the user to upload or
download instrument settings to or from a USB memory stick. This allows easy configuration of multiple instruments by copying from one to another, or to transfer it to or from the PC configuration software. If the
Data Recorder or Profiler options are fitted, recordings
and profile information can also be transferred via USB
memory stick. Refer to the USB Menu section for more
details.
Note: To speed up the disk operation, keep the number
of files in these folders to a minimum
USB Memory Stick Folders & Files
When a USB stick is inserted, the instrument looks for,
and if necessary creates the DEVICE, CONFIG, PROFILE and RECORDER folders. Files must be located
in these folders in order to be used. When preparing to
upload files from your PC, ensure that you save them
to the correct folder on the memory stick.
Do not remove the memory stick from the USB
port whilst a data transfer operation is in progress. Data loss or corruption may result.
DEVICE – This folder must be located in the
Root of the USB memory stick
CONFIG – Configuration files (*.bct)
PROFILE – Profile program files (*.pfl)
RECORDER – Recorder log folders/files The
user is asked for a new recorder sub-folder
name before transferring recorder data to USB.
The instrument stores the log files (*.csv) in this
folder.

9 The Data Recorder Option
Calibration Reminder
The features covered in this section are available on
models fitted with the Data Recorder option. This option includes a USB Interface (refer to section 8) and a
Real Time Clock (RTC) with battery backup.
A “calibration due reminder” can be shown if the date
is equal to or after the Calibration Reminder Date. The
reminder screen persists until the
key is pressed. If
due, the reminder is shown at Power-up, and repeated
every 24hrs until the reminder date is changed. The
Calibration Reminder enable/disable and Reminder
Date parameters can be set from the Input Configuration Menu.
Introduction
The Data Recorder option allows the user to make a
recording of the process over time. Recordings can be
transferred to a memory stick using the USB Port.
Recordings are stored in Comma Separated format
(.csv), suitable for use with spreadsheets, or for import
in to other software. See the USB Memory Stick Folders & Files details (in section 8) for file information.
Memory Use Bar Graph
The bar-graph shown in the main Operation Mode
screen can be set to show 0 to 100% of recorder memory used instead of the standard options of PID power
or control deviation. The Bar Graph Format is defined
in the Display Configuration Menu.
A Recorder Configuration sub-menu is added to the
Configuration Menu and Recorder Control can be optionally added to the Main Menu or Operation Mode.
The RTC also expands the profiling capabilities (refer
to section 10) and allows a “calibration due” reminder
to be shown at a date specified by the user.
Changes To Operation Mode
The Data Recorder adds the option for a Calibration
Reminder and a % memory use bar graph to the Operation Mode screen sequence.
10 The Profiler Option
Profile Components
The features covered in this section are only available
on models fitted with the Profiler (Setpoint Programmer) option. If the instrument also has the Data Recorder option fitted, its Real Time Clock is used to expand the profiling capabilities by adding Day & Time
profile start options, releasing of hold segments at a
specific time of day and changing the power fail recovery option to one based on the length of time the power
has been off. These features are explained below and
in the Profiler Setup and Profile Control menus (refer to
section 7)
The General Profile Configuration settings decide how
profiles can be Run, Held or Aborted. These settings
apply to all profiles.
Each profile has its own header information, plus 1 or
more segments.
Profile Header & Segment Information
The profile header contains information about how the
profile starts and stops, the power loss recovery action
and how many times it should be repeated.
Introduction
Note: Profile Header information is stored to memory
as the Segment creation sequence begins. No profile is
created if you exit before this point.
The Profiler option allows the user to store up to 255
profile segments, shared between a maximum of 64
Profiles. Each profile controls the value of the setpoint
over time; increasing, decreasing or holding its value
as required. If fitted, Profiler options are added to the
Main Menu as well as the Operation Mode.
Segments can be ramps, dwells, steps or special segments such as holds, ends or joins. Note: Segment information is stored as each segment is created, but the
profile remains invalid until an end or join segment is
defined.
Profiler Enabling
Controllers supplied without the Profiler option installed can be upgraded in the field by purchasing a
licence code number from your supplier. Refer to the
Field Upgrade information (Section 3) for more details.
36
Profile Starting & Standard Segments
The example profiles below contain examples of the
standard segment types required to make simple profiles or profile sequences. A Start Trigger is the instruction to begin the selected profile. Depending on the
Run/Hold Signal parameter setting in the Profile Setup
Menu, this can be from a Key-press given in the appropriate screen, a digital input signal or via a serial
communications command.
A timer start time should not clash with other profiles. A profile will not start if another
is running. Remember that delays caused by
manual holds or Auto-Hold can effect when the
previous running profile will finish.
Following a Start Trigger, profiles can start immediately,
after a delay, or from the Timer (Timer start available on
Recorder version only).

Profile Starting and Standard Segment Types
Ramps, Dwells and Step Segments each have an end
of segment Target Setpoint.
A Dwell (sometimes called a soak) holds the last segment’s value for the specified Dwell Time.
If a segment is a Ramp-Time type, the slope needed
to reach the target in the defined time will change depending on the Starting Setpoint value. For a RampRate segment, the slope is defined by the segments
Ramp Rate, so the time to reach the target setpoint will
change instead. This is of particular significance for the
first segment, since the starting value of the process
may not be known.
Step segments jump straight to the new target setpoint
value.
An End segment ends the profile sequence.
If the last segment is a Join, the join target profile will
start.
Note: The Profile sequence will abort if the join target
has been deleted.

Loops Segments
continues onwards. More than one Loop Segment can
be used in a profile, but they must not cross.
A Loop Segment goes back to a specified segment in
the current profile. This action is repeated for the required number of times (1 to 9999) before the profile

Runs segments 1 to 5, then
repeats segments 3 to 5 for 500
times, before continuing on to

Hold Segments
Run/Hold & Hold Segments
A Hold during a segment maintains the current setpoint value. Once the hold condition is stopped the
Ramp or Dwell continues. Depending on the configuration, a hold can be the started & stopped by via a keypress, breaking the signal to a Run/Hold digital input,
a serial comms command or by the Auto-Hold feature
(see below).
A Hold Segment is a pre-planned hold, programmed
into the profile. It maintains the value of the previous
segment. The profile does not continue until a Continue Trigger occurs. This can be via a key-press, a digital
input signal or after waiting for a time of day (available
on Recorder version only).
Note: A running profile will also hold while Manual
Control is selected.
38
The Auto-Hold Feature
During a Dwell, the dwell time is increase by the time
that the process is outside of the hold band in the selected direction(s). This ensures the process was at the
desired level for the required amount of time.
Each profile segment has individual Auto-Hold settings.
If utilised, these ensure that the profile and the actual
process remain synchronised. If the process does not
closely match the required setpoint by remaining within
the defined Hold Band, the profile can be held until it
returns within bounds.
During a Ramp segment, the ramp is held at the current setpoint value while the process is outside of the
hold band in the selected direction(s). The time taken
to complete the ramp is increased by the time taken by
the Auto-Hold.
The user can choose to hold the profile if the process
goes beyond the Hold Band Above The Setpoint only,
Below The Setpoint only or to Band (either side of the
setpoint). When Auto-Hold becomes active, the profile
status is shown as “Held”.

Profile Cycles & Repeat Sequences
If there is a break in the input while a program is running, the unit will go to the Pre-Set Power Value during
the break condition. Once the condition has ended it
carries out the same recovery action as specified for
power failure.
A profile can be configured to run itself 1 to 9999 times
or continuously using the Profile Cycles setting. A profile ending with Repeat Then End will run the entire
sequence of profiles again from 1 to 9999 times before
ending.
Note: Recorder versions always use option E (Continue profile from the point it had reached when the power
failed) if the Power Off Time is less than the Profile Recovery Time setting. If the power is off for more than
this time, the defined Profile Recovery Method is used.
Power/Signal Lost Recovery Actions
If there is a power cut while a profile is running, the instrument will use the defined Profile Recovery Method
once the power has been restored.

11 Manually Tuning Controllers
Single Control Tuning (PID with Primary
Output only)
2. Set the Setpoint to the normal operating value for
the process (or to a lower value if overshoots beyond this value might cause damage).
This 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 and the Integral
and Derivative time constants that allow the PID control algorithm to give acceptable results in most applications that use a single control device.
3. Select On-Off control (i.e. set the Primary Proportional Band to zero).
4. Switch on the process. The process variable will oscillate about the setpoint. Record the Peak-to-Peak
variation (P) of the first cycle (i.e. the difference between the highest value of the first overshoot and
the lowest value of the first undershoot), and the
time period of the oscillation (T) in minutes. See the
example diagram below - Manually Tuning PID.
This technique is suitable only for processes
that are not harmed by large fluctuations in the
process variable.
5. Calculate the PID control parameters using the formula below. P.Pb is the Primary Proportional Band,
Int.T is the Integral Time Constant, and Der.T is the
Derivative Time Constant. The Input Span is the
difference between Scale Range Lower Limit and
Scale Range Upper Limit:
1. Check that the Setpoint Upper Limit and Setpoint
Lower Limit are set to safe levels for your process.
Adjust if required.

Dual Control Tuning (PID with Primary and
Secondary Outputs)
PI Tuning (Valve, Damper & Speed
Controllers)
This 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, Secondary Proportional Band, Integral and Derivative time
constants that allow the PID control algorithm to give
acceptable results in most applications that use dual
control (e.g. Heat & Cool).
This tuning technique is used when controlling a
damper, a modulating valve or motor speed controller. It determines values for the Primary Proportional
Band, and Integral Time Constant. The Derivative
Time Constant is normally set to OFF. This type of
control (known as PI Control) minimises valve/motor
wear whilst giving optimal process control.
This technique is suitable only for processes
that are not harmed by large fluctuations in the
process variable.
This technique is suitable only for processes
that are not harmed by large fluctuations in the
process variable.
1. Set the setpoint to the normal operating process
value (or to a lower value if overshoot beyond this
value is likely to cause damage).
1. Tune the controller using only the Primary Control
output as described in the Single Control Tuning
section above.
2. Set controller to On/Off Control mode (i.e. set Primary Proportional Band to the minimum value).
2. Set the Secondary Proportional Band to the same
value as the Primary Proportional Band and monitor the operation of the controller in dual control
mode. If there is a tendency to oscillate as the control passes into the Secondary Proportional Band,
increase its value. If the process appears to be overdamped (slow to respond) in the region of the Secondary Proportional Band, decrease its value.
3. Set the Integral Time Constant to OFF.
4. Set the Derivative Time Constant to OFF.
5. Follow the instructions in the diagram on the following page. At each stage, allow sufficient settling
time before moving on to the next stage. P.Pb is the
Primary Proportional Band, Int.T is the Integral Time
Constant
3. When the PID tuning values have been determined,
if there is a disturbance to the process variable as
control passes from one proportional band to the
other, set the Overlap/Deadband parameter to a
positive value to introduce some overlap. Adjust
this value by trial and error until satisfactory results
are obtained.

Fine Tuning.
Note: Allow enough time for the controller and process
to adjust between changes.
A separate cycle time adjustment parameter is provided for the Primary and Secondary control when using
time proportioning control outputs.
4. Initially add Derivative at a value between 1/4th and
1/10th of the Integral Time value.
5. Increase the Derivative Time if the process overshoots/undershoots, increase its value a little at a
time, if the process becomes unstable, until the oscillation stops. Induce a load disturbance or make a
setpoint change to verify that the process stabilises.
If not decrease the value some more and re-test.
Note: Adjusting the cycle time affects the controllers
operation; a shorter cycle time gives control that is
more accurate, but mechanical components such as
relays will have a reduced life span.
1. Increase the width of the proportional band if the
process overshoots or oscillates excessively.
Note: When controlling a modulating valve, it is recommended that Derivative is set to OFF to avoid excessive valve activity. Derivative can cause process instability in these processes.
2. Decrease the width of the proportional band if
the process responds slowly or fails to reach setpoint.
3. To find the optimum value for the Integral Time, decrease its value until the process becomes unstable,
then increase it a little at a time, until stability has is
restored. Induce a load disturbance or make a setpoint change to verify that the process stabilises. If
not increase the value some more and re-test.
6. After making all other adjustments, if an offset exists between the setpoint and the process variable
use the Bias (manual reset) to eliminate the error:
Below setpoint - use a larger value
Above setpoint - use a smaller value
12 Serial Communications
Supported Protocols
RS485 Device Addressing
Communication with a Modbus RTU or Modbus TCP
master device is possible if the appropriate communications module is fitted into Option Slot A. ASCII is
no longer supported on the 4080. An RS485 Module is
required for Modbus RTU. An Ethernet Module is required for Modbus TCP.
The instrument must be assigned a unique device address in the range 1 to 255. This address is used to recognise Modbus Queries intended for this instrument.
With the exception of globally addressed broadcast
messages, the instrument ignores Modbus Queries
that do not match the address that has been assigned
to it.
The instrument can also act as Setpoint Master over
RS485 in multi-zone applications. In this mode the unit
continuously sends its setpoint value using Modbus
broadcast messages.
The instrument will accept broadcast messages (global
queries) using device address 0 no matter what device
address is assigned. No response messages are returned for globally addressed Queries.
For a complete description of the Modbus protocol refer
to the description provided at http://www.modbus.org/
Ethernet Configuration
All models also have a configuration socket for use
with the PC configuration software. An RS232 to TTL
lead (available from your supplier) is required in order
to use this socket.
For Modbus TCP communications (Modbus over Ethernet), the IP address can either be assigned by a Dynamic Host Configuration Protocol (DHCP), BootP or
AutoIP server on the network, or manually assigned
using the IP address allocation software tool.
A front mounted USB port is available on some models;
this can also be used to configure the instrument or to
transfer recorder or profile files via a USB memory stick.
Refer to the PC Software section of this manual for
more information setting IP addresses.
RS485 Configuration
The supported data rates 10/100BASE-T (10 or 100
Mbps) are automatically detected.
The RS485 address, bit rate and character format are
configured via the front panel from the Comms Configuration menu or by using the PC Configurator software.
Physical layer configuration settings possible are:
Data rate:
4800, 9600, 19200, 38400,
57600 or 115200 bps
Parity:
None (default), Even, Odd
Character format:
Always 8 bits per character.
Device Address:
See following.
45
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 - the transmitter must not
start transmission until 3 character times have elapsed
since reception of the last character in a message, and
must release the transmission line within 3 character
times of the last character in a message.
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.

at 4800bps.
QUERY
Data is encoded for each character as binary data,
transmitted LSB first.
For a QUERY the address field contains the address
of the slave destination. The slave address is given
together with the Function and Data fields by the Application layer. The CRC is generated from the given
address, function and data characters.
RESPONSE
Figure 47.
For a RESPONSE the address field contains the address of the responding slave. The Function and Data
fields are generated by the slave application. The CRC
is generated from the address, function and data characters.

13 Modbus Parameters
The Modbus parameter register addresses are detailed
in the tables below.
The Modbus Address column shows the register address for each parameter in integer format. Other formats can be calculated from the Integer Only address.
The Access column indicates if a parameter is read
only (RO) or if it can also be written to (R/W). Communications writes will not be implemented if the Writing
Via Serial Comms parameter in the Communications
Configuration menu is set to Disabled.
When working in Hexadecimal, the format calculations are:
Address for Integer with 1 Decimal Place = Integer address plus 0x4000
Note: Some parameters that do not apply for a particular configuration will accept reads and writes (e.g.
attempting to scale a Linear output which has not been
fitted). Read only parameters will return an exception if
an attempt is made to write values to them.
Address for Floating Point = Integer address
multiplied by 2, plus 0x8000
When working in Decimal, the format calculations are:
Address for Integer with 1 Decimal Place = Integer address plus 16384
Data Formats
Data can be read or written in three formats: Integer
Only, Integer with 1 Decimal Place and Floating Point
Number.
Address for Floating Point = Integer address
multiplied by 2, plus 32768

a specified profile position
Advanced users can setup or edit profiles by writing
to the Profile Configuration parameter at address 8198
(0x2006). This can only be accessed by using Modbus
function code 23 (0x17). The instrument replies with a
status message.
If this profile number is already in use then the
profile header data is overwritten but the segments associated with it are kept.
When creating a new profile the steps below must be
followed exactly, either to create a profile at the next
available position, or at a position that you specify.
1. Determine which profile positions are being used by
using the Command Code value PS (0x50, 0x53).
This command will return a list of all the profile positions currently being used.
Each message in the sequence includes a 2 byte Command Code that tells the instrument the purpose of the
message, and therefore the meaning of the data contained in it.
2. Choose a location that is not being used and write
the profile header data using the Command Code
value WP (0x57, 0x50).
Instruction Sequence to create a profile at
the next available position
The profile number is echoed back by the instrument in
the Edit Response Message.
1. Create a profile by writing the profile header data
using the Command Code value CP (0x43, 0x50).
This starts the profile creation process by reserving
a profile memory slot. The profile number is returned
by the instrument in the Edit Response Message.
3. Write the first segment using the Command Code
value Code WS (0x57, 0x53). This command will fill
the next available segment position and link it to the
profile created in step 1.
4. Write the second segment, again using Command
Code WS. This fills the next available segment position and links it to the segment created in step 2.
2. Write the first segment using the Command Code
value Code WS (0x57, 0x53). This command will fill
the next available segment position and link it to the
profile created in step 1.
3. Write the second segment, again using Command
Code WS. This fills the next available segment position and links it to the segment created in step 2.
5. Continue writing segments until the profile is complete (whilst remaining within the overall limit of 255
segments for all profiles combined). Each of these
segments fills the next available position and links it
to the previous segment specified.
4. Continue writing segments until the profile is complete (whilst remaining within the overall limit of 255
segments for all profiles combined). Each of these
segments fills the next available position and links it
to the previous segment specified.
6. The very last segment of the profile must be one of
the end type segments. Thereafter, no more segments can be added to the specified profile. To add
a segment to an existing profile the insert segment
command must be used.

Instruction Sequence to edit an existing
Profile Header
2. Use the command RS to read the 1st segment’s
data
3. Use the command RS to read the 2nd segment’s
data.
When a profile header is changed, the segments associated with it remain unchanged. They must be edited
separately if required.
4. Repeat steps 2 and 3 until an end segment is
reached.
1. Determine the number of the profile to be edited.
Use the Command Code value PS (0x50, 0x53)
which returns a list of all profile positions/numbers
currently in use.
The following rules apply when creating a profile over
communications:
• Profiles must always be terminated with an end
segment.
• Segments cannot be added after an end segment has been added.
• All changes made to the selected profile are immediately saved in the instrument.
2. Write a new profile header data using the Command
Code value EP (0x45, 0x50).
The profile number is echoed back by the instrument in the Edit Response Message.

Creating, Editing or Inserting Segments
The Edit Segment command is used to alter segments
of an existing profile.
Creating new segments is only possible when a new
profile is being created (see above for instruction for
creating a profile at the next available position, or at
a position that you specify). An error is returned if the
correct sequence is not followed.
The segment number is in relation to the profile number, e.g. to edit or insert a segment at position 3 of
profile 1 the segment number will be 3, and to edit or
insert a segment at position 3 of profile 6 the segment
number will also be 3.
The Insert Segment command is used to add segments to an existing profile (one that already has an
end segment). This inserts a new segment at the position specified.

14 Calibration
Recalibration Procedure
Recalibration is carried out in five phases as shown in
the table below; each phase corresponds to a basic
input type.
CALIBRATION IS ONLY REQUIRED FOR INSTRUMENTS IN WHICH CALIBRATION ERRORS HAVE
BEEN ENCOUNTERED. REFER TO CALIBRATION CHECK BELOW.
The 50mV phase MUST be calibrated before
the thermocouple range.
Calibration must be performed by personnel
who are technically competent and authorised
to do so.
Table 27. Input Calibration phases
DC milli-volt Calibration
50 mV
Calibration Reminder
DC voltage Calibration
10 V
Calibration of each input type is carried out during
manufacture. This can be verified from Product Information Mode. Recorder versions can provide the user
with a calibration reminder if the application requires
regular checks – see Input Configuration for details.
DC milliamps Calibration
20 mA
RTD Calibration

For most applications, re-calibration is not required
during the lifetime of the instrument.
1. For optimum accuracy, power-up the instrument for
30 minutes, then toggle the power off/on to restart
the instrument.
Equipment Required For Checking or
Calibrating The Universal Input
2. During the power-up “splash screen”, press
and
together until the Calibration Status screen
is displayed.
A suitable calibration signal source is required for each
input type. To verify the accuracy of the instrument
or carry out recalibration, the listed input sources are
required. These must have better than ±0.05% of the
reading accuracy:
3. Press
to select the first calibration phase (50mV
Calibration)
4. Ensure that an accurate 50mV signal has been applied to terminals 2 (+ve) and 3 (-ve), then press
and
to initiate the calibration.
1. DC linear inputs: 0 to 50mV, 0 to 10VDC and 0 to
20mADC.
5. During calibration the message “50mV DC Input
Calibrating” will display for a few seconds. This
should be followed by the “Calibration Successful”
confirmation.
2. Thermocouple inputs - complete with 0ºC reference
facility, appropriate thermocouple functions and
compensating leads (or equivalent).
6. If the input is misconnected or an incorrect signal is
applied, the calibration will be aborted and the display will show “Failed: Signal Too Small!” or “Failed:
Signal Too Large!”.
3. RTD inputs: decade resistance box with connections for three-wire input (or equivalent).
Calibration Check
The previous calibration value will be retained.
1. Set the instrument to the required input type.
7. Press
2. Power up the instrument and connect the correct
input leads.
8. Repeat this process for each input type until all the
phases are calibrated. For each phase, ensure that
the correct input is applied, using the correct connections.
Leave powered up for at least five minutes for RTD
and DC linear inputs, and at least 30 minutes for
thermocouple inputs.
to select the next calibration phase.
9. Once all calibration phases are completed, recorder
versions will display the Calibration Reminder Date.
If required, this can be changed to the date of your
next calibration check. Ensure that Calibration Reminders are enabled in Input Configuration to receive a reminder.
3. After the appropriate delay for stabilisation, check
the calibration by connecting the appropriate input
source and checking a number of cardinal points.
The observed readings should be within the tolerances stated in the Specification (see Appendix 2)
Press
4. Repeat the test for all required input types.

15 Appendix 1 - Glossary of Terms Used
Active Setpoint
Alarm Hysteresis
The term Active Setpoint is used to describe the currently selected setpoint when the instrument is in Controller Mode. Controllers can use Local Setpoint 1 and/
or the Alternative Setpoint. Only one of the setpoints
can be active at any time. During Profiler Control, the
setpoint value is controlled by the profiler function.
An adjustable band through which the process variable must pass before the alarm will change state. This
Hysteresis is only applicable to alarms based on the
Process Value or Control Deviation, as illustrated below. The band is always on the “safe” side of an alarm
point, e.g. a high alarm’s hysteresis band is below the
high alarm value, and a low alarm’s hysteresis is above
the low alarm value. Rate Of Change Alarms have a
different type of hysteresis based on the length of time
the rate is above the threshold.
Also refer to: Actual Setpoint, Alternative Setpoint,
Controller Mode, Local Setpoints, Profiler Mode, Remote Setpoint, Setpoint, and Setpoint Selection.
Settings = 1 LSD to full span from the setpoint.
Default value = 1 LSD.
Actual Setpoint
Actual Setpoint is the effective current value of the active setpoint. This will be different to the Active Setpoint’s target value if the setpoint is ramping. The actual setpoint will rise or fall at the ramp-rate set, until it
reaches its target setpoint value. During Profiler Control, the Actual Setpoint value is controlled by the profiler function.
Refer to the Alarm Hysteresis Operation diagram on
the next page.

Alarm Inhibit
Settings = Enabled or Disabled. Default value = Disabled.
Alarm Inhibit prevents unwanted process or deviation
alarm activation at power-up or when the controller
setpoint is changed. The alarm activation is inhibited
until a ‘Safe’ condition is present. The alarm operates
normally from that point onwards. E.g. if inhibited, a
low alarm will not activate at power-up, until the process has first risen above the alarm point and then falls
back below.
Also refer to: Pre-Tune, Self-Tune, PID and Tuning.
Automatic Reset
- Refer to Integral Action
Auxiliary Input
Settings = Inhibit or not inhibited for each alarm.
Default value = None Inhibited.
Up to two secondary linear input modules can be installed in Option Slot A and B. These can be used as
Remote Setpoint inputs. Signals can be mA, mV, VDC
or Potentiometer. Auxiliary Input B also has a Digital
Input onboard.
Also refer to: Alarm Types and Alarm Operation.
Alarm Types
Also refer to: Alternative Setpoint, Digital Input, Linear
Input, mADC, mVDC, Remote Setpoint and VDC
There are four basic alarm types, Process Alarms, Control Deviation Alarms, Rate of Signal Change Alarms
and Event Based Alarms.
Auxiliary Input Lower Limit
Process Alarms are based on the absolute value of the
Process Variable. If the PV rises above a high alarm
value, or falls below a low alarm value, the alarm will
become active. Deviation Alarms are based on the value of the Control Deviation error. If the PV is more than
the high deviation alarm value above setpoint, or more
than the low deviation alarm value below setpoint, the
alarm will become active.
When the auxiliary input is used to provide a Remote
Setpoint (RSP), this setting defines the value of the
RSP when the auxiliary input signal is at its minimum
value (e.g. for 4 to 20mA, the value when 4mA is applied). It may be adjusted within the range -1999 to
9999. However, the RSP value is always constrained
by the setpoint upper limit and Lower Limits.
Settings = -1999 to 9999
Range Lower Limit.
Rate Of Signal Change Alarms are based on the rate of
change of the PV. If the rate of change is greater than
the alarm value for longer that the Minimum Duration
time, the alarm will activate.
Default Value = Scale
Also refer to: Auxiliary Input, Auxiliary Input Upper
Limit, Auxiliary Input Offset, Remote Setpoint, Setpoint
and Setpoint Upper Limit and Setpoint Lower Limit.
Event based alarms activate when the condition for
that alarm type is true. These can be Signal Break, Low
Memory Or Loop Alarms.
Auxiliary Input Offset
Also refer to: Alarm Operation, Band Alarm Value, Control Deviation, Deviation Alarm, Loop Alarm, Process
High Alarm, Process Low Alarm, Process Variable,
Rate Of Change Alarm, and Setpoint.
Used to adjust the value of the Auxiliary Input. Positive values are added to the auxiliary input reading,
negative values are subtracted. It is adjustable in the
range –1999 to 9999. When the auxiliary input is used
to provide a Remote Setpoint, this setting is added to
(or subtracted from) the remote setpoint value, but the
setpoint is still constrained by the etpoint upper and
lower limits.
Alternative Setpoint
The instrument can have up to two setpoints. Local
Setpoint 1 and/or an Alternative Setpoint. The Alternative Setpoint can be chosen from Local Setpoint 2 or
a remote setpoint input from Auxiliary Input A or B if
either of these are fitted. One setpoint can be chosen
as the active at using the Setpoint Selection.
Settings = ±input span Default Value = Off.
Also refer to: Auxiliary Input, Remote Setpoint, Scale
Range Upper Limit, Scale Range Lower Limit Setpoint
Lower Limit and Setpoint Upper Limit.
Also refer to: Auxiliary Input, Local Setpoints, Remote
Setpoints; Setpoint and Setpoint Select.
Auxiliary Input Type
Auto Pre-Tune
Defines the type and range of the linear input signal for
the Auxiliary Input. It can be mADC, mVDC, VDC or potentiometer (mVDC and potentiometer are only available with the Full Auxiliary input in option slot B). This
can be used as a Remote Setpoint input.
When the Auto Pre-Tune is enabled, a Pre-Tune activation is attempted at every power-up (standard PreTune activation rules apply). Auto Pre-Tune is useful
when the process to be controlled may vary significantly each time it is run. Auto Pre-Tune ensures that
the process is tuned correctly each time the process
is started. Self-Tune may also be engaged to fine-tune
the controller.
Also refer to: Remote Setpoint and Setpoint.
107
Auxiliary Input Upper Limit
Bumpless Transfer
When the auxiliary input is used to provide a Remote
Setpoint (RSP), this setting defines the value of the
RSP when the auxiliary input signal is at its maximum
value (e.g. for 4 to 20mA, the value when 20mA is applied). It may be adjusted within the range -1999 to
9999. However, the RSP value is always constrained
by the setpoint upper limit and Lower Limits.
A method used to prevent sudden changes to the correcting variable, when switching between automatic
PI or PID and Manual control modes. During a transition from PI or PID to Manual control, the initial Manual
Power value is set to the previous automatic mode
value. The operator then adjusts the value as required.
During a transition from Manual control to PI or PID,
the initial automatic value is set to the previous Manual
mode value. The correcting variable level will gradually
adjusted by the control algorithm at a rate dependant
on the integral action resulting from the Integral Time
Constant value. Since integral action is essential to
Bumpless Transfer, this feature is not available if Integral is turned off.
Settings = -1999 to 9999
Range Lower Limit.
Default Value = Scale
Also refer to: Auxiliary Input, Auxiliary Input Lower
Limit, Auxiliary Input Offset, Remote Setpoint, Setpoint
and Setpoint Upper Limit and Setpoint Lower Limit.
Band Alarm Value
Also refer to: Correcting Variable, Integral Action, Manual Mode, PI and PID.
The amount of control deviation that is acceptable before a Band Alarm is activated. If the process variable
is more than the value of this band from the actual setpoint, the alarm will be active.
Cascade Control
Applications with two or more capacities (such as
heated jackets) are inherently difficult for a single instrument to control, due to large overshoots and unacceptable lags. The solution is to cascade two or more
controllers, each with its own input, in series to form a
single regulating device. The product setpoint temperature is set on the master controller. This is compared
to the product temperature, and the master’s PID output (mA or VDC) is fed into the auxiliary input of the
slave controller as a remote setpoint input. The RSP
is scaled to suit any expected temperature. The slave
loop’s natural response time should ideally be at least
5 times faster than the master.
Settings = 1 LSD to full input span from the setpoint.
Default value = 5 LSD’s.
Also refer to: Actual Setpoint, Alarm Operation, Alarm
Types, Control Deviation, Input Span, LSD and Process
Variable.
Bar Graphs
The instrument displays a bar-graph in the base operation mode screen. These can show
PID Power Output (single control = uni-directional,
dual control = bi-directional), Control Deviation (bidirectional) or for Data Recorder version %Memory
Used (uni-directional). Bar-graphs are uni-directional
or bi-directional depending on the information to be
displayed.
In the example, the maximum input represents 400ºC,
thus restricting the jacket temperature. At start-up the
master compares the product temperature (ambient) to
its setpoint (300ºC) and gives maximum output. This
sets the maximum (400ºC) setpoint on the slave, which
is compared to the jacket temperature (ambient) giving
maximum heater output.
Also refer to: Control Deviation, Data Recorder, Display
Configuration, Operation Mode, Main Menu and PID
Bias (Manual Reset)
Used to manually bias proportional output(s) to compensate for control deviation errors due to process load
variations. Bias is expressed as a percentage of output
power. This parameter is not applicable if the Primary
output is set to ON-OFF control. If the process variable settles below setpoint use a higher Bias value to
remove the error, if the process variable settles above
the setpoint use a lower Bias value. Integral action performs a similar function automatically when using PI or
PID control.
Lower Bias values will also help to reduce overshoot at
process start up.
As the jacket temperature rises, the slave’s heater output falls. The product temperature also rises at a rate
dependant on the transfer lag between the jacket and
product. This causes the master’s PID output to decrease, reducing the ‘jacket’ setpoint on the slave, effectively reducing the output to the heater. This continues until the system becomes balanced.
Settings = 0 to 100% (-100% to +100% for dual control).

When tuning a cascade system, first set the master to
manual mode. Tune the slave controller using proportional control only (I & D are not normally required) then
return the master to automatic PID mode before tuning
the master. The result is quicker, smoother control with
minimum overshoot and the ability to cope with load
changes, whilst keeping the jacket temperature within
acceptable tolerances.

CPU
Deadband
This stands for Central Processing Unit and refers to
the onboard microprocessor that controls the measurement, control, alarm and display functions of the
instrument.
Derivative Action
- Refer to Overlap/Deadband.
The Derivative Time Constant defines how the control
action responds to the rate of change in the process
variable. The power is decreased if the PV is rising,
or increased if the PV is falling. This parameter is not
available if primary control output is set to On-Off, and
it is normally set to OFF in modulating value applications as it can cause premature wear due to constant
small adjustments to the valve position.
Current Proportioning Control
Current proportioning control is used to produce the
correcting variable on units with linear output(s). It
provides 4 to 20mA, 0-20mA, 0 to 5V, 0 to 10V or 2
- 10V DC for proportional control, PI, PD or PID control modes. On-Off control cannot be used with linear
outputs.

Defines the amount of control deviation considered acceptable before a deviation alarm is activated. A positive value (deviation high) sets the alarm point above
the current actual setpoint, a negative value (deviation
low) sets the alarm point below actual setpoint. If the
process variable deviates from the actual setpoint by
a margin greater than this value, the deviation alarm
becomes active. If an alarm is required if the control
deviation is either side of the setpoint, consider using a
Band alarm or a logical combination of a deviation high
and deviation low alarm.
Also refer to: Control Configuration, Display Configuration and Operation Mode
Cycle Time
For time proportioning outputs, the cycle time is used to
define the time over which the controller averages the
ON vs. OFF time, in order to provide the required correcting variable. Each Time-Proportioning output has
its own adjustable cycle time. Shorter cycle times give
better control, but at the expense of reduce life when
used with electromechanical control devices (e.g. relays or solenoid valves). There are separate cycle times

The Process Variable and Setpoint displays can assigned engineering units to describe the type of parameter connected to the process input. The engineering units for linear inputs can be: °C; °F; °K; bar; %;
%RH; pH; psi or none. For temperature inputs (RTD or
Thermocouples) they can be °C; °F or °K.
Direct Acting Control
Also refer to: Linear Input, Process Input, Process Variable RTD and Thermocouple
Direct action is required for applications where the primary control output will be used to force the process
variable down towards the setpoint. A typical application is a Chiller. When the control action is selected as
direct acting, primary proportional control outputs decrease the correcting variable as the process variable
reduces within the proportional band, and primary OnOff outputs turn off when the process variable is less
than the setpoint. The control action of a secondary
output is always the opposite of the primary output.
Ethernet
A networking technology for local area networks
(LANs). Used to link computers and other equipment
in order to control or share data and control such devices. If fitted with an Ethernet serial communications

Control, PID, Pre-Tune, Process Variable and Tuning.
A loop alarm detects faults in the control feedback loop,
by continuously monitoring process variable response
to the control output(s). If one of the 5 alarms is defined to be a loop alarm, it repeatedly checks if the PID
control output is at saturation. If saturation is reached
(0% or 100% power for single control type, -100% or
+100% for dual control type), an internal timer is started. Thereafter, if the output has not caused the process
variable to be corrected by a predetermined amount ‘V’
after time ‘T’ has elapsed, the alarm becomes active.
Subsequently, the alarm repeatedly checks the process variable and the PID output. When the process
variable starts to change value in the correct sense or
when the PID output is no longer at the limit, the alarm
is deactivated.
LSD
The Least Significant Digit (LSD) is the smallest incremental value that can be shown at the defined display
resolution.
Also refer to: Display Resolution.
mADC
This stands for milliamp DC. It is used in reference to
the linear DC milliamp input ranges and the linear DC
milliamp outputs. Typically, these will be 0 to 20mA or
4 to 20mA.
For PID control, the loop alarm time ‘T’ can be automatic (twice the Integral Time value) or set to a user
defined value. Correct operation with the automatic
loop alarm time depends upon reasonably accurate
PID tuning. The user defined value is always used for
On-Off control, and the timer starts as soon as an output turns on.

Main Menu
The top-level menu that allows access to operation
mode as well as all other menus. These are: configuration mode, profiler setup and recorder menus, the setup wizard, supervisor mode and the tuning and USB

The value of ‘V’ is dependent upon the input type. For
Temperature inputs, V = 2°C or 3°F. For Linear inputs,
V = 10 x LSD
The loop alarm is automatically disabled during manual control mode and during execution of a Pre-Tune.
Upon exit from manual mode or after completion of
the Pre-Tune routine, the loop alarm is automatically
re-enabled.

matching a remote setpoint input. It is possible to apply an offset to each zone if the slave has a Setpoint
offset parameter or by offsetting its remote setpoint input (or adjusting the scaling of this input).
Manual Loop Alarm Time
The loop alarm time used when a loop alarm is defined
to have a manually set time or whenever On-Off control is selected. This parameter determines the duration
of the output saturation condition after which the loop
alarm will be activated.

Manual Mode
Minimum Duration Of Change
If Manual Mode is enabled/disabled (from the control
configuration sub-menu, or the Auto/manual screen in
operation mode if it is available) it allows the controller to switch between automatic and manual control
modes. Auto/Manual Mode can also be switched using
a digital input if one has been configured for this function. Switching between automatic and manual modes
is achieved using “bumpless transfer”.
A form of alarm hysteresis unique to the Rate Of Change
Alarm. It is the minimum time that the rate of change in
the process variable must be above the alarm threshold, before the alarm will change state (from on to off,
or off to on).
Settings = 1 to 9999 secs.
Default value = 1sec.
Caution: If the duration is less than this time, the alarm
will not activate no matter how fast the rate of rise.
Manual Mode operates as follows:
The setpoint legend is replaced by the word MAN and
setpoint value is replaced by a % output power value.
This value may be adjusted using the
or
keys.
The power value can be varied from 0% to 100% for
controllers using single control type, and -100% to
+100% for controllers using dual control type. It is possible to use a controller as a permanent “Manual Station” by selecting Manual Control in the control configuration sub-menu.
Also refer to: Alarm Hysteresis, Alarm Types and Rate

Modbus RTU
Modbus RTU is the serial communications protocol
used on instruments fitted with the RS485 Communications module into Option Slot A. Alternatively, the
Modbus TCP protocol is available if the Ethernet Communications Module is fitted.
Modbus RTU is a Master/Slave protocol. Only the Master may initiate communications. Each slave is given a
unique address, and the message contains the Modbus address of the intended slave. Only this slave will
act on the command, even though other devices might
receive it (an exception is specific broadcast commands sent to address 0 which are acted upon by all
slaves but not acknowledged).
Manual Mode should be used with care because the power output level is set by the operator, therefore the PID algorithm is no longer
in control of the process. The operator MUST
maintain the process at the desired level manually. Manual power is not limited by the Power
Output Limits.
The commands can instruct the slave to change a value in one of its registers, or ask it to send back one
or more values contained in its registers. The Modbus
RTU format follows the messages with a cyclic redundancy check (CRC) checksum to ensure that the message arrives undamaged.
Also refer to: Bumpless Transfer, Control Configuration,
Control Type, Operation Mode, PID, and Power Output
Limits.
Master & Slave Controllers
This instrument can act as a Slave or as a Setpoint
Master over RS485. In this mode the unit continuously
sends its setpoint value using Modbus broadcast messages.
The terms master and slave are used to describe the
controllers in multi-zone applications where one instrument controls the setpoint of another. These can be
simple Setpoint Master/Slave applications where the
master controller transmits its setpoint to the slaves
via serial communications, or retransmits it as an analog DC linear output signal. If serial comms are used,
the master controller must be able to act as a communications master device and the slave must have a
compatible communications option fitted. If DC linear

Modbus TCP
On-Off Control
Modbus TCP is a version of the Modbus protocol for
networks that support the Internet Protocol, such as
Ethernet. It is available if the Ethernet Communications
Module is fitted into Option Slot A.
When operating in On-Off mode, the control output(s)
will turn on or off as the process variable crosses the
setpoint in a manner similar to a central heating thermostat. Some oscillation of the process variable is inevitable when using On-Off control.
This instrument can only act as a Slave when using
Modbus TCP. A master device initiates the communications, and the instrument only acts on the command
if it has been sent to its IP address. The data model
and function calls used by Modbus TCP and RTU are
identical; only the encapsulation is different. Modbus/
TCP does not require a checksum to ensure that the
message arrives intact.
On-Off control can be implemented only with Relay,
Triac or SSR driver outputs. On-Off operation can be
assigned to the Primary output alone (secondary output not present), Primary and Secondary outputs or
Secondary output only (with the primary Output set for
time proportional or current proportional control). OnOff Control is selected by setting the corresponding
proportional band(s) to On-Off.
Refer to the Serial Communications and Modbus Parameter sections of this manual for more information.

Modulating Valve
On-Off Differential (On-Off Hysteresis)
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. This instrument
can control modulating valves that have a positioning
circuit. These require proportional (mA or VDC) control
signal from a linear output, relative to the desired valve
position. PI control is used for valve control.
A switching differential, centred about the setpoint,
when using On-Off control. Relay ‘chatter’ can be
eliminated by proper adjustment of this parameter, but
too large a value may increase process variable oscillation to unacceptable levels. On-Off differential is also
known as hysteresis or deadband.
Settings = 0.1% to 10.0% of input span. Default value
= 0.5%.
To directly control the valves ‘open’ and ‘close’ motor
windings, a special Valve Motor Drive (VMD) controller algorithm is required. This instrument does not currently support this type of algorithm.

view, information about the process, alarms plus optionally, selection of auto/manual control, control output disabling. Recorder and profiler information can be
displayed if these features are fitted. Up to 50 configuration menu screens can be defined with the PC software, and will be shown if the Custom Display mode is
enabled in the Display Configuration sub-menu.
Multi-Point Scaling
If the process input is connected to a linear input signal, multi-point scaling can be enabled in the Input
Configuration sub-menu. This allows the linearization
of a non-linear signal.
The Scale Range Upper & Lower Limits define the values shown when the input is at minimum and maximum values, and up to 15 breakpoints can scale input
vs. displayed value between these limits. It is advisable
to concentrate these break points in the area of the
range that has the greatest amount of non-linearity, or
the area of particular interest in the application.

Overlap/Deadband
rameter has the effect of moving the On-Off Differential
band of the Secondary Output to create the overlap or
deadband. When Overlap/Deadband = OFF, the edge
of the Secondary Output Differential band coincides
with the point at which the Primary Output = 0%.
The Overlap/Deadband parameter defines the portion
of the primary and secondary proportional bands over
which both outputs are active (called Overlap), or neither is active (called Deadband). This is adjustable in
the range -20% to +20% of the sum of the two proportional bands. Positive values = Overlap, negative
values = Deadband.
The effect of the Overlap/Deadband parameter is

PID control, but without Integral action.
PLC This stands for Programmable Logic Controller. A microprocessor based device used in machine control. It
is particularly suited to sequential control applications,
and uses “Ladder Logic” programming techniques.
Some PLC’s are capable of basic PID control, but tend
to be expensive and often give inferior levels of control.
Also refer to: Derivative, Integral, PID Control, Proportional Control and Tuning.
PI Control
Proportional and Integral Control (PI) is most often used
for modulating valve or motor control. It combines proportional control with integral action. It is similar to PID
Control, but without derivative action that can cause
excessive valve movement.
Also refer to: PID.
Pre-Tune
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 full Secondary Power is applied for Dual Control),
thereby introducing an oscillation. Once the oscillation
peak has passed, the Pre-Tune algorithm calculates an
approximation of the optimum PID tuning terms proportional band(s), integral and derivative. The Pre-Tune
process is shown in the following diagram.
Also refer to: Derivative, Integral, Modulating Valve, PID
Control, Proportional Control and Tuning.
PID Control
Proportional Integral and Derivative control maintains
accurate and stable levels in a process (e.g. when controlling a temperature). Proportional Control avoids the
oscillation characteristic of On-Off control by continuously adjusting the correcting variable output(s) to keep
the process variable stable. Integral action eliminates
control deviation errors, and Derivative action counters
rapid process movements.
When Pre-Tune is completed, the PID control output
power is applied using the calculated values. Pre-Tune
limits the possibility of setpoint overshoot when the
controller is new or the application has been changed.

Process Input
Pre-Tune can be selected from the Automatic Tuning
Menu. It will not engage if either primary or secondary
outputs on a controller are set for On-Off control, during setpoint/profile ramping or if the process variable is
less than 5% of the input span from the setpoint. As a
single-shot operation, Pre-Tune will automatically disengage once complete, but can be configured to run at
every power up using the Auto Pre-Tune function.
The main input used to monitor the value process to
be controlled. This is known as the Process Variable or
PV. The input circuit is a “Universal” type, supporting
all common thermocouples and PT100 RTDs as well as
DC linear mV, voltage or mA signals suitable for almost
any parameter that can be converted into a electronic
signal. Linear signals can be scaled into engineering
units using the Scale Range Lower Limit and Scale
Range Upper Limit parameters.

Power Output Limits
Process Low Alarm n Value
Used to limit the power levels of the primary and secondary control outputs. Normally the instrument can
set these outputs to any value between 0% and 100%.
If this is undesirable in a particular application, individual settings can limit the primary power upper and
lower levels and the secondary power upper and lower
levels. The upper limit values must be higher than the
lower limits. These parameters are not applicable if that
output is set for On-Off control.
An independent low alarm value parameter is available
for each alarm that is set as Process Low type. It defines the process variable value below which Alarm n
will be active.

Process Variable (PV)
Process Variable is the parameter that is to be controlled. It is monitored by the main process input of the
instrument, and can be any type that can be measured
by that circuit. Common types are Thermocouple or
RTD temperature probes, or pressure, level, flow etc
from transducers that convert these parameters into
DC linear input signals (e.g. 4 to 20mA). Linear signals
can be scaled into engineering units using the Scale

Primary Proportional Band
The portion of the input span over which the Primary
Output power level is proportional to the process variable value. 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 Process variable offset is used to modify the measured process variable value. Use this parameter to
compensate for errors in the displayed process variable. Positive values are added to the process variable
reading, negative values are subtracted. Caution: This
parameter is in effect, a calibration adjustment; it must

Profile Control Menu
Profiler
If the Profiler option is fitted, a Profile Control menu
is available from the Main Menu. It allows the user to
select or run a profile, and then control that profile (run,
hold, abort, skip to next segment etc.).
A profiler controls the value of the actual setpoint over
time; increasing, decreasing or holding its value as required. This is used in applications where the rate of
rise or fall of the process variable must be closely controlled, or where a value must be maintained for a period before moving to the next value.
Refer to the Profiler Control Menu information in the
Configuration & Use section.
If the Profiler option is fitted, up to 64 profiles can
be created with a maximum of 255 profile segments
shared amongst them. Each segment can activate/deactivate the five events according to the requirements
of the process.
Also refer to: Main Menu, Profile Setup Menu, Profiler
and Profiler Mode.
Profile Events
Events are outputs that can be made active during
profile segments. There are 5 possible events, each
of which can be defined to be active or inactive for
the duration of each segment, from the Profile Setup
Menu. For end segments, events selected to be active
stay on until the unit is powered down or a new profile
runs. It is possible to link event outputs to certain alarm
outputs in a logical AND situation.
Refer to the Profiler Option section.
Also refer to: Actual Setpoint, Controller Mode, Profile
Events, Profile Control Menu, Profile Header, Profile
Segments, Profile Setup Menu and Profiler Mode.
Profiler Mode
This mode is entered when a profile is run. In profiler
mode, additional screens are added to Operation Mode
which show the status of the profile. These screens are
not seen in Controller Mode. The instrument will remain
in Profiler Mode when the profile finishes or is aborted
unless the Segment End Type/Profile Abort Action is
set to “Use Controller Setpoint”.
Also refer to: Alarm Types, Logical Combinations, Profile Segments, Profile Setup Menu, Profiler and Profiler

The profile header contains information about how the
profile starts and stops, the power loss recovery action
and if the profile should repeat multiple times when run.

Profile Segments, Profile Setup Menu, Profiler and Setpoint.
Refer to the Profile Components information in the Profiler Option section of this manual.
Proportional Control
Also refer to: Profile Segments, Profile Setup Menu,
Profiler and Profiler Mode.
Proportional control allows the correcting variable applied to the process to be set between 0 and 100% of
the amount available. If the control type is dual, two
outputs (primary & secondary) are available, each of
which can give proportional control. When the Proportional Band(s) are correctly tuned, the process variable
is maintained at a steady value, avoiding the oscillation
characteristic of On-Off control. Proportional control is
most commonly used in conjunction with Integral and
Derivative action to give PI. PD or PID control.
Profile Segments
Segments can be ramps, dwells, steps or special segments such as holds, ends or joins. A maximum of 255
segments are possible, shared amongst up to 64 profiles.
Refer to the Profile Components information in the Profiler Option section of this manual.

or PLC. The output can be scaled to transmit any portion of the input or setpoint span.
Recorder Configuration
If the Data Recorder is fitted, a Recorder Configuration sub-menu is added to Configuration Mode. This
is used to adjust the recorder parameters (Recording

Retransmit Output n Scale Maximum
Scales a linear output module in slot n if it has been
selected to retransmit the PV or SP. Retransmit Scale
Maximum defines the value of the process variable, or
setpoint, at which the output will be at its maximum
value. E.g. for a 0 to 5V output, it is the PV or SP value
corresponding to 5V. If this parameter is set to a value
less than that for Retransmit Output n Scale Minimum,
the relationship between the process variable/setpoint
value and the retransmission output is reversed so that
higher PV/SP values give a lower output level.

Relay
An electromechanical switch operated by a solenoid
coil. Relays are commonly fitted as internal, time proportioning controller outputs. The limited current capacity and switching cycles of internal relays means
that they are usually connected to larger external slave
relays/contactors which are capable of switching much
larger currents and are easily replaced once worn out.
A suitably rated RC snubber should be connected to
relays to protect nearby equipment from the effects of
noise generated as they switch (refer to the Noise Suppression details in the Electrical Installation section).
Retransmit Output n Scale Minimum
Also refer to: Current Proportioning Control, Latching
Relay, SSR Driver, Time Proportioning Control and Triac
Scales a linear output module in slot n if it has been
selected to retransmit the PV or SP. Retransmit Scale
Minimum defines the value of the process variable, or
setpoint, at which the output will be at its minimum
value. E.g. for a 0 to 5V output, it is the PV or SP value
corresponding to 0V. If this parameter is set to a value
greater than that for Retransmit n Output Scale Maximum, the relationship between the process variable/
setpoint value and the retransmission output is reversed so that higher PV/SP values give a lower output
level.
Remote Setpoint (RSP)

If the alternative setpoint type is selected to be a remote setpoint, and the selected setpoint is the alternative setpoint, an Auxiliary Input value is used to adjust the controller setpoint. The auxiliary linear input, is
given a VDC or mADC signal, or in some cases potentiometer or mV inputs. The Remote Setpoint value is
constrained by the Setpoint Upper Limit and Setpoint
Lower Limit settings. Typical applications are Setpoint

Reset To Defaults
RTD
This Configuration sub-menu selection returns all of
the instruments settings back to their factory defaults.
It should be used with great care, as the action cannot be undone. A reset is followed automatically by
the Setup Wizard. Users must use this wizard and/or
configuration menus to set all of the parameters to the
correct values for the intended application.
Resistance Temperature Detector. A temperature sensor that changes resistance with a change in the measured temperature. This instruments process input
supports PT100 (platinum, 100Ω at 0°C) and NI120
(nickel, 120Ω at 0°C) sensors. These have positive
temperature coefficients (PTC) which means their resistance increases with higher temperatures. The temperature measured by the sensor can be displayed as
°C; °F or °K.
Also refer to: Configuration Menu, and Setup Wizard
Also refer to: Input Range, Process Input and Thermocouple.
Reverse Acting Control
Reverse control action is required for applications
where the primary control output will be used to force
the process variable up towards the setpoint. A typical application is a furnace. When the control action is
selected as reverse acting, primary proportional control
outputs decrease the correcting variable as the process variable increases within the proportional band,
and primary On-Off outputs turn off when the process
variable exceeds the setpoint. The control action of a
secondary output is always the opposite of the primary
output.
Scale Range Upper Limit
For linear inputs, this parameter is used to scale the displayed process variable. It defines the displayed value
when the process variable input is at its maximum value
(e.g. if 4 to 20mA represents 0 to 14pH, this parameter
should be set to 14). The value can be set anywhere
from -1999 to 9999 and can be set to a value less than
(but not within 100 LSDs of) the Scale Range Lower
Limit, in which case the sense of the input is reversed.
Also refer to: Control Action, Control Type, Correcting Variable, Direct Acting Control, On-Off Control and

RS485
RS485 (also known as EIA-485) is two-wire, half-duplex, multi-drop serial communications connection.
RS485 only defines the physical layer electrical specification, not the protocol that is transmitted across it.
It uses differential signals (the voltage difference between the wires) to convey data. One polarity indicates
a logic 1, the reverse polarity indicates logic 0. The applied voltages can be between +12 V and -7 volts, but
the difference of potential must be > 0.2 volts for valid
operation. RS485 can span distances up to 1200 metres using inexpensive twisted pair wires. Data speeds
can be as high as 35 Mbit/s over 10 m and 100 kbit/s
at 1200 m.

Scale Range Lower Limit
For linear inputs, this parameter is used to scale the
displayed process variable. It defines the displayed
value when the process variable input is at its minimum
value (e.g. if 4 to 20mA represents 0 to 14pH, this parameter should be set to 0). The value can be set from

It is recommended that the wires be connected as series of point-to-point (multi-dropped) nodes (not in a
star or ring format), with 120ohm termination resistors
connected across the wires at the two ends of the network. Without termination resistors, reflections of the
signals can cause data corruption, and electrical noise
sensitivity is increased. The master device should normally provide powered resistors, to bias the wires to
known voltages when they are not being driven by any
device. Without biasing resistors, the data lines float
and noise can be interpreted as data when actually all
devices are silent.

The deviation signal is shown shaded, and overshoots
have been exaggerated for clarity. The Self-Tune algorithm observes one complete deviation oscillation
before calculating a new set of PID values. Successive
deviation oscillations cause the values to be recalculated so that the controller converges on optimal control.
When the controller is switched off, these PID terms
are stored, and are used as starting values at the next
switch on. The stored values may not always be ideal, if
for instance the controller is brand new or the application has changed. In these cases, the user can utilise
Pre-Tune to establish new initial values. Self-Tune will
then fine-tune these values as it monitors any control
deviation.
Setpoint
The target value at which the instrument attempts to
maintain the process variable, by adjusting its control
output power (the correcting variable). There can be
either one or two setpoints. Local Setpoint 1 and/or
an Alternative Setpoint. The Alternative Setpoint can
be chosen from Local Setpoint 2 or a remote setpoint
input from Auxiliary Input A or B if either of these is fitted. One setpoint can be chosen as active using the
defined Setpoint Selection method. Setpoint values are
limited by the Setpoint Upper Limit and Setpoint Lower
Limits.
Use of continuous self-tuning is not always appropriate. For example applications which are frequently
subjected to artificial load disturbances, for example
where an oven door is likely to be frequently left open
for extended periods, can lead to errors in the calculations. In addition, because Self-Tune tunes for full PID
control, it is not recommended for valve control applications, which normally require PI control.

Setpoint Ramp Rate
Solid State Relay (SSR)
The rate at which the actual setpoint value will move
towards its target value, when the setpoint value is adjusted or the active setpoint is changed. With ramping
in use, the initial value of the actual 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.
Settings = 1 to 9999 LSDs per hour.

An external device manufactured using two Silicone
Controlled Rectifiers in reverse parallel. They can be
used to replace mechanical relays in most AC power
applications. Some special SSRs can switch DC, but
most cannot. As a solid-state device, an SSR does not
suffer from contact degradation when switching electrical current. Much faster switching cycle times are
also possible, leading to superior control. The instrument’s SSR Driver output provides a time-proportioned
10VDC pulse for to the SSRs signal input terminals.
This causes conduction of current from the line supply
through the SSR to the load, when the pulse is on.

Solenoid Valve
An electromechanical device, use to control the flow of
gases or liquids. It has just two states, open or closed.
Usually, a spring holds the valve closed until a cur123
rent is passed through the solenoid coil forces it open.
Standard process controllers with time-proportioned
or On-Off outputs can be used to control these types
of valves.
ear mA or voltage output signal can be controlled.
Solenoid valves are often used with high/low flame gas
burners. A bypass supplies some gas at all times, but
not enough to heat the process more than a nominal
amount (low flame). A controller output opens the solenoid valve when the process requires additional heat
(high flame).
Time Proportioning Control
Also refer to: Control Deviation, Linear Output, Modulating Valve, and Valve Motor Control
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(s). The PID control algorithm determines the
ratio of time (on vs. off) to achieve the level of the correcting variable required to remove the control deviation error. E.g. for a 32 second cycle time, 25% power
would result in the output turning on for 8 seconds,
then off to 24 seconds. This type of output might be
used with electrical contactors, solid state relays or
solenoid valves. Time proportioning control can be implemented with Relay, Triac or SSR Driver outputs for
either primary or secondary outputs.
Also refer to: Modulating Valves, On-Off Control and
Time Proportioning Control.
Supervisor Mode
Supervisor Mode allows access to a lock code protected sub-set of the main configuration parameters.
The unlock code is different from the higher level Configuration Menu unlock code. Up to 50 Configuration

none have been chosen, this mode is disabled.

doted line), or the minimum and maximum value of the
process variable measured since the last sample. Any
active alarm(s) are indicated above the graph. The user
can scroll the right hand cursor line back to examine
all 240 data points. The sample interval and data to
display is set in Display Configuration.
Thermocouple
A temperature sensor made from two different metals. They convert temperature difference between their
cold junction (the measuring instrument) and the hot
junction, into a small signal or a few microvolts per °C.
Thermocouples are cheap and interchangeable, but
the wires and connectors used must match the metals
used in their construction. They can measure a wide
range of temperatures; some thermocouples can withstand very high temperatures such as furnaces. The
main limitation of thermocouples is accuracy.
The temperature measured by the thermocouple can
be displayed as °C; °F or °K.
Also refer to: Alarm Types, Display Configuration, Operation Mode, and Process Variable, Setpoint.
The color codes for the common types are shown in
the Thermocouple Wire Identification Chart in the Electrical Installation Section of this manual.
Tuning
Also refer to: Engineering Units, Input Range, Process
Input and RTD.
PID Controllers must be tuned to the process in order
for them to attain the optimum level of control. Adjustment is made to the tuning terms either manually, or
by utilising the controller’s automatic tuning facilities.
Tuning is not required if the controller is configured for
On-Off Control.
Three Point Stepping Control
Modulating valves normally require a special “Three
Point Stepping” control algorithm. This which provides
an output to move the valve further open, or further
closed whenever there is a control deviation error.
When this error is zero, no further output is required to
maintain control unless load conditions change. This
type of controller is often called a Valve Motor Drive
controller. This instrument does not currently have a
three point stepping algorithm.
Also refer to: Auto Pre-Tune, Controller, Derivative Action, Integral Action, On-Off control, PID, Pre-Tune, Primary Proportional Band, Self-Tune, Secondary Proportional Band and Tuning Menu.
Tuning Menu
The Tuning Menu can be accessed from the Main
Menu. This menu is lock code protected.
However, modulating valves that have a valve positioning circuitry to adjust the valve position from a DC lin-
It gives access to the Pre-tune, Auto Pre-Tune and Self124
tune facilities. These assist with PID tuning, by setting
up Proportional band(s), Integral and Derivative parameter values. Tuning is not required for On-Off control.
If the Data Recorder option is present, the recordings
can be downloaded to the stick for transport to the users PC for analysis. If the Profiler option is present, profiles can be downloaded to the stick or upload to the
instrument using a pre-stored file that was downloaded
earlier, created using the PC software, or even taken
from another instrument.
Pre-tune can be used to set PID parameters approximately. Self-tune may then be used to optimise the tuning if required. Pre-tune can be set to run automatically
after every power-up by enabling Auto Pre-Tune.
Refer to the Automatic Tuning information in the Configuration & Use section.

Valve Motor Drive Control (VMD)
Also refer to: Data Recorder, Lock Codes, Main Menu
and Profiler
This instrument can only control modulating valves that
have a valve positioning circuitry that adjusts the valve
position according to the level a DC linear mA or voltage output signal. Such valves normally require PI control instead of full PID.
Triac
A small internal solid state relay, which can be used in
place of a mechanical relay in applications switching
low power AC, up to 1 amp. Like a relay, the output
is time proportioned, but much faster switching cycle
times are also possible, leading to superior control. As
a solid-state device, a Triac does not suffer from contact degradation when switching electrical currents. A
snubber should be fitted across inductive loads to ensure reliable switch off the Triac. A triac cannot be used
to switch DC power.
Motorzed modulating valves that do not have this type
of circuit require special Valve Motor Drive controllers
which have a “Three Point Stepping” control algorithm.
Solenoid valves can also be controlled using the standard PID algorithm as they behave in a similar way to
relays, having just two states, open or closed.

Configuring The Connection
A front mounted USB port is available on some models; this can also be used to configure the instrument or
transfer profile files, via a USB memory stick.
The software can communicate with the instrument
via the RJ11 configuration socket located on the underside of the case, or via the Modbus TCP or RS485
communications options if either is fitted. Refer to the
wiring section for connection details.
The configuration lead/socket is not isolated
from the process input or SSR Driver outputs.
It is not intended for use in live applications.
The configuration socket is intended for initial configuration of the instrument before installing in the application. An RS232 to TTL lead (available from your supplier) is required connect from the PCs RS232 serial
port to this socket.
130
A communications settings screen is shown whenever
the user attempts to connect to the instrument from
the software. The settings must be correct in order for
communications to work successfully. First correctly
select Configuration Socket or Bus as the Device connector, and select the PC Serial Com port that you
have connected to
For Modbus TCP, select Ethernet (bus coupler).
If connecting via the configuration port, the Start and
Stop bits must be 1 and Data bits 8. Parity must be
None and address 1. The data bit-rate should be 4800
if Slot A is fitted with an Auxiliary input, 9600 if the Ethernet option is installed or 19,200 for a Digital Input or
if Slot A is empty.
If the instrument has an RS485 module fitted, the Address, Parity and Bit rate values must match those of
the instrument (even if you are connecting via the configuration port). The Start and Stop bits must be 1 and
Data bits 8.
If connecting via the Modbus TCP module, enter the instrument’s IP address and set the Port address to 502

Network Configuration For Modbus TCP
Options
If your network assigns IP addresses automatically,
pressing the “Search Network” button will list any of
the Graphical Controllers connected to it.
If the instrument has the Modbus TCP communications
option fitted, an IP address must be assigned to it in order for it to communicate with the Modbus TCP master
device over your Ethernet network. The instrument can
automatically receive an IP address if your network is
set up to assign addresses to Ethernet devices connected to it. Alternatively, a fixed IP address can be
assigned to it manually.
Their Network IP Address and MAC Addresses are also
shown. For most fixed networks, only instruments that
have the same numbers in the first 3 Octets of their IP
address can be seen by the PC. In this case, use the
method detailed in the “Fixing An IP Address” section
below.
Highlight the instrument that you wish to configure in
the list and press the “Configure Selected Device Button”.
The Graphical Controller Ethernet Configuration tool is
provided in order to discover or assign the IP Address
of the instrument and configure the settings.
The Current IP address on the network is shown in the
Edit IP Address tab, as is the current configured IP address. A configured address of 0.0.0.0 means the instrument does not have a fixed address, allowing it to
receive one from the network (via a DHCP, BootP or
AutoIP server).
Setting the IP Address
Install and run the Graphical Controller Ethernet Configuration software on your PC. Connect the instrument
to your network by plugging an Ethernet cable into the
RJ45 socket on the top of the case. If your PC is not
connected to a network, the instrument can be connected to its Ethernet port directly.
Set the value to 0.0.0.0 for automatic addressing, or
set a new fixed IP address and press Apply.
Note: If this number does not match your PC’s network
addresses, further communication with the instrument
will cease.
132
Instrument Details
The Details tab can be used to confirm communications with the instrument. When opened or refreshed,
this tab collects the instruments Serial Number, Date
of Manufacture and the Contact Details information,
confirming that the Modbus TCP communications is
functioning correctly.
Fixing An IP Address
Edit Modbus Settings
*If your instruments 12 digit MAC Address isn’t know, it
can be found on a label attached to the RJ45 connector of its Ethernet module.
If your instrument cannot be found using the “Search
Network” button, the IP address can be set from the
Set IP Address option on the software’s System menu.
Enter its MAC Address* and the new IP Address (use
0.0.0.0 for automatic addressing) then press okay.
The Edit Modbus Settings tab configures the connection between the Ethernet module and the instrument’s
microprocessor. These settings MUST match with the
settings in the instruments Communications Configuration menu. A faster baud rate can be used if large
amounts of data are to be sent between the instrument
and the master, but in most cases, it is recommended
that the default settings are used.
