1.1 Unpacking
Carefully remove the product from its packing. Please
retain the packing for future use.
A single sheet concise manual is also supplied in one
or more languages. Examine the delivered items for
damage or defects. If any are found, contact your supplier immediately.
1.2 Cleaning
Clean the front panel by wiping down with a dry cloth.
Never allow water or any other substances to ingress
into the instrument.
1.3 Installation
Installation should only be 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.
This instrument is designed for indoor back of panel
use.
(121 mm)
3.90”
(99 mm)
4.84”

This equipment is protected throughout by
double insulation, when installed properly.
This type of installation does not need an earth
connection, but it is vital for safety reasons,
that the instrument is replaced if the instrument housing is broken.
The optional bus connection should be slid onto the
DIN Rail before fitting the 1020/1030 Rail.
The connectors must be pushed together to share the
bus.

2 Electrical Installation
The 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).
2.1 Installation Considerations
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.
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.
Noise-generating devices such as those listed above
should be mounted in a separate enclosure.
If this is not possible, separate them from the instrument, by the largest distance possible.
If possible, eliminate mechanical contact relays and
replace with solid-state relays. If a mechanical relay
cannot be replaced, a solid-state relay can be used to
isolate the instrument.
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.
2.2 AC Power Wiring - Neutral (for
100 to 240V AC versions)
It is good practice to ensure that the AC neutral is at or
near ground (earth) potential. A proper neutral will help
ensure maximum performance from the instrument.
2.3 Wire Isolation
Four voltage levels of input and output wiring may be
used with the unit:
• Analogue input (for example thermocouple, RTD,
VDC, mVDC or mADC)
• Relays outputs
• SSR Driver outputs
• AC power
The only wires that should run together are
those of the same category.
If any wires need to run parallel with any other lines,
maintain a minimum space of 6” between them. If wires
MUST cross each other, ensure they do so at 90 degrees to minimize interference.
2.4 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.
2.5 Noise Suppression at Source
Usually when good wiring practices are followed, no
further noise protection is necessary. Sometimes in
severe electrical environments, the amount of noise is
so great that it must be suppressed at source. Many
manufacturers of relays, contactors, etc. will 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.
2
Page 9
Inductive coils: - MOVs are recommended for transient suppression in inductive coils, connected in parallel and as close as possible to the coil. Additional
protection may be provided by adding an RC network
across the MOV.
Figure 5. 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.
2.6 Sensor Placement (Thermocouple or
RTD)
If the temperature probe is to be subjected to corrosive
or abrasive conditions, it must be protected by an appropriate thermowell. The probe must be positioned to
reflect true process temperature: In a liquid media, the
most agitated area. 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 (10 ft.). Use of three
wire RTDs is strongly recommended.
2.7 Panel Wiring
In general, all wiring connections are made to the instrument after it is installed. Copper wires must be
used for all connections (except thermocouple signal
wires).
To avoid electrical shock, AC power wiring
must not be connected to the source distribution panel until all wiring procedures are completed.
Check the information label on the case to determine the correct voltage before connecting
to a live supply.

2.8 Terminal Wiring
The diagram shows all possible option combinations.
Please check the product configuration before wiring.
Dedicated Configuration Socket (on bottom of the instrument)
The wiring label shows the power requirements, connector positions and terminal number.
This example is:
TOP
1 & 2 Rear = RS485 Comms
3 & 3 Rear = Linear Out 3
5 & 6 Front = SSR Driver Out 2
7 & 8 Front = 100-240VAC power.
BOTTOM
9 & 10 Rear = Digital Input
11, 12 Rear & 16 Front = Relay Out 1
13, 14 & 15 Front = Process Input
2.9 Power Connection
To avoid damaging your instrument it is critical the
power connection is made to the correct terminals
Power is connected to pins 7 & 8.
Top, rear connector on the right-hand side.
(front connector omitted from picture for clarity)
The green LED shows when power is correctly connected.
NEVER DIRECTLY CONNECT THIS SOCKET TO

3 Powering Up
ENSURE SAFE WIRING PRACTICES HAVE BEEN
FOLLOWED. WHEN POWERING UP FOR THE
FIRST TIME, DISCONNECT THE OUTPUT CONNECTIONS.
3.2 First Power Up or Factory De-
fault
When the unit is initially powered up or the user restores
the factory defaults to the device, it immediately enters
the Setup menu without requiring an unlock code. The
user must then cycle through every parameter, to either
view or adjust the value, and then exit the menu.
Check carefully the supply voltage and connections before applying power.
The instrument must be powered from a supply according to the wiring label on the side of the unit. (100vac
to 240Vac, or 24 Vac/dc depending upon the model
purchased.)
3.1 Powering Up Procedure
At power-up, a self-test procedure is run, during which
a product logo screen is displayed.
When powering up for the first time the instrument
starts up in the Setup Mode after the product logo
screen is displayed.
You must complete the Setup by
cycling through all of the parameters
before using the device for the first
time.
1. Use or to review every parameter.
2. Change value if necessary using , then
use or to adjust the value, then to save.
3. Exit Setup by pressing & together.
If the above steps are not followed the Setup has not
been completed so the device will go into Setup, again,
on every subsequent power up.
3.3 Auto-Tune
The controller can be auto-tuned from the Setup Mode.
1. Pre-tune
2. Auto-tune at setpoint
Auto-Tuning will not engage if:
• Controller is set to On/Off Control
• Setpoint is ramping
• PV is within 5% of the input range
from setpoint
3.4 Front Panel
Display shows PV (process variable), units, SP (setpoint), alarm/latch statuses,
error & warning messages.
By default, the display turns off after 5 minutes without any key presses.
3 navigation keys:
Ok/Select
Up
Down
This is configurable in the Advanced Configuration, in the Display submenu, parameter Screen Timeout. Any key press turns the display back on.
Standard:
3 Output Status LEDs
1 2 3
Extrusion:

3.5 General Navigation & Editing
• Press or keys to navigate between parameters or menu items.
• Press to highlight a parameter value, ready for
editing.
• Press or to change the parameter value, then press within 60 seconds to confirm
change.
3.6 Mode (or Menu) Structure
There are 3 main modes (or menus) on the device –
Setup and Advanced Configuration Mode.
• User Mode - the live screen used for normal operation. The process variable can always be seen in
this mode
• Setup Mode – allows access to the most important
parameters
• Advanced Configuration Mode - access all parameters via sub-menus
Setup Mode - press & .
Advanced Configuration - press & .
Never connect the instrument’s configuration
socket directly to a USB port as it will damage
the controller.
3.7 Returning to Operator Mode
3.9 Use of the Controller for NonTemperature Applications
In the majority of applications this controller will be
used for temperature sensing, either via a sensor or a
linear DC input, which use heat and cool. However this
controller can be used for other types of processes.
If your process is not a temperature then the parameters labelled as “HEAT”refer to reverse acting outputs
used to increase the process value and “COOL” to decrease the process value.
As an example you may have a system that reads and
controls humidity. The “HEAT” output drives the humidifier and the “COOL” output drives the de-humidifier. Use the “HEAT” parameters to control the humidifier
and the “COOL” parameters to control the de-humidifier.
Often the “HEAT” and “COOL” is referred to as “Primary” and “Secondary” on other controllers.
3.10 Controller Transmitter Function
The Standard 1020 & 1030 model can be used as a
“transmitter” to retransmit the process value or controller setpoint via Output 3, if the linear option is fitted.
The parameter Usage in the Linear Output sub-menu
can be set to PV Retransmit or SP Retransmit.
In the Display menu, the parameter Transmitter can be
used to enable Transmitter view. This hides the Setpoint from view.
Control functions will remain active if
they have been configured.
Press & to move back one level
From a sub-menu you will need to do this twice; once
to return to Advanced Configuration Mode then again
to exit. After 120 seconds without key presses the unit
returns automatically to the first Operator mode screen.
3.8 Mode Access and Lock Codes
Separate lock codes can be set for the Setup mode
and for the Advanced Configuration mode.
• Setup mode lock code – default 10.
• Advanced Configuration mode lock code – default
20.
Hold the button while powering up for a read-only
view of lock codes.

8 Calibration Mode
Low Process Value
Original Displayed Value
It is possible to calibrate the controller to compensate
for sensor errors and other tolerance errors in the system. This is achieved using the calibration mode. The
calibration mode allows an offset to be applied in one
of two ways. The method used will be dependent on
the process application.
These methods do not alter the internal
instrument calibration. Set the offset
values back to zero to restore standard
measured values. Re-calibration of the
internal base calibration is also possible,
but should only be attempted by qualified
personnel as it overwrites the factory
calibration – see Base Input Calibration
below.
8.1 Single Point Calibration (PV Offset)
This is a ‘zero offset’ applied to the process variable
across the entire span. Positive values are added to the
reading, negative values are subtracted. It can be used
if the error is constant across the range, or the user
is only interested in a single critical value. To use, select Single Point Calibration from the input calibration
menu, and simply enter a value equal, but opposite to
the observed error to correct the reading.
This example shows a positive offset value.
8.2 Two Point Calibration
This method is used where an error is not constant
across the range to change the calibration slop. Separate offsets are applied at two points in the range to
eliminate both “zero” and “span” errors.
1. Measure and record the error at a low point in the
process.
2. Measure and record the error at a high point in the
process.
3. Go to the first two-point input calibration screen.
a. Enter the desired low point value as the Calibra-
tion Low PV value.
b. Enter an equal, but opposite value to the ob-
served error as the Calibration Low Offset to correct the error at the low point.
4. Go to the second two-point input calibration screen.
a. Enter the desired high point as the Calibration
High PV value.
b. Enter an equal, but opposite value to the ob-
served error as the Calibration High Offset to
correct the error at the high point.
Calibration High Offset
Single Point ‘Offset
Calibration’ value
New Displayed Value
Original Displayed Value
For example: If the process displays 27.8 when it
should read 30, The error is -2.2 so an applied offset
of +2.2 would change the displayed value to 30. The
same offset is applied to all values, so at 100.0 the new
displayed value would be 102.2.
New Displayed Value
Calibration Low Offset
Calibration
Choose values as near as possible to the bottom and top of your usable span to achieve
maximum calibration accuracy. The effect of
any error can grow at values beyond the chosen calibration points.
The single and two-point calibration methods can be
used together, if you need to change the calibration
slope and offset the zero point simultaneously.

8.3 Base Input Calibration
Calibration of the input is carried out during manufacture, and for most applications, re-calibration is not
required during the lifetime of the instrument. User
1-point and 2-point calibration can be carried from the
User Calibration menu.
Re-calibration of the internal base values
is possible, but should only be attempted
by qualified personnel as it overwrites
the factory calibration.
A suitable calibration signal source is required for each
input type. To verify the accuracy of the instrument or
carry out re-calibration, the input sources listed below
are required, with better than ±0.05% of the reading
accuracy:
1. DC linear inputs: 0 to 50mV dc, 0 to 10V dc & 0 to
20mA dc.
2. Thermocouple inputs - complete with 0ºC reference
facility, appropriate thermocouple functions and
compensating leads (or equivalent).
3. RTD inputs: decade resistance box with connections for three-wire input (or equivalent).
8.5 Base Calibration Procedure
Input calibration is carried out in five phases as shown
below, each phase corresponds to an input range of
the instrument.
The 50mV phase must be calibrated first before any other range(s).
Calibration phases:
i. mV for 50 mV
ii. V for 10 V
iii. mA for 20 mA
iv. RTD input (200Ω ohm resistance source)
v. CJC (K type thermocouple source at 0ºC required)
For Extrusion models phase ii and iii (V & mA) are omitted.
8.6 Calibrating the mV Input
1. Check your calibration source is connected to the
correct terminals on the 1020 Rail. For 50mV, connect your mV source +ve to pin 14 and -ve to pin 15
located on the bottom rear connector – see wiring
section.
8.4 Calibration Check
1. Set up the instrument to the required input type.
2. Note down, then remove any single or two-point
calibration values by setting them to zero.
3. Power up the instrument and connect the correct
input leads, to the correct terminals.
4. Leave powered up for at least five minutes for RTD
and DC linear inputs, or at least 30 minutes for thermocouple inputs.
5. After the appropriate delay for stabilization has
elapsed, check the calibration by connecting the
appropriate input source and checking a small
number of cardinal points.
6. Repeat the test for all required input types.
7. Check the results against the specification stated
for the required input type.
8. Reinstate the calibration values removed at step if
they are still appropriate.
Make the connections using the correct thermocouple cable type. For all other input types
use copper cable. Using the wrong type of cable will cause incorrect readings. This is especially important with thermocouple sensors.
2. Press and hold the button, whilst the instrument

9 Automatic Tuning
To avoid process time-lags that can make effective
tuning difficult or even impossible, ensure correct sensor and heat source positioning in your application before use.
There are two automatic tuning methods on the 1020
and 1030 controllers. Pre-Tune and Tune at SP.
The Pre-Tune is a ‘start-up disturbance’ tuning method. It usually gives better results than Tune at SP.
However, a minimum 5% of span distance between
the process value and setpoint is required for Pre-Tune
to run. This means it cannot be used if the setpoint is
close to ambient temperature. In this case, use Tune at
SP. A full description of Pre-tune and Tune at SP is in
the Glossary.
Refer to the Warnings & Messages
section for information on the Tuning
Error messages.
9.1 Running the Pre-Tune
1. For best results, before running the Pre-Tune adjust
the input span (Scale Range Maximum and Scale
Range Minimum) to suit your process, allowing a
small tolerance beyond the operating range. e.g. if
operating from ambient to 180°C, perhaps set the
range 0 to 200.
2. Run from cool. Ideally the process should to be cool
before running Pre-Tune. Disable control, or temporarily lower the setpoint, until the PV is a least 5%
of the input span difference between the current SP
and PV. A larger gap is better if this is possible.
3. Allow for overshoot and undershoot. Please be
aware that when the Pre-Tune is run, full power
is applied to the process for some time. Although
the controller cuts power before the setpoint is
reached, some process over/undershoot should be
expected. The overshoot might exceed the setpoint
value. If exceeding SP might cause a problem, run
your first Pre-Tune with a lower SP. If required and
safe to do so, you can run another Pre-Tune closer
to the required SP.
4. The Pre-Tune can be activated via the Automatic
Tuning parameter in the Setup menu or the Advanced Configuration menu. It may also be activated via a Modbus command.
The message ‘TUNE’ is displayed whilst Pre-Tune is
running.
Pre-Tune will not engage, and a Tune Error message
will be displayed under the following conditions: 1)
There is a sensor break, 2) The PV is <5% of span
from SP, 3) A setpoint ramp has been set, 4) A Timer
is running, 5) The current control mode is On-OFF
6). The controller is in Manual mode. 7) Control is
Disabled*. Resolve the displayed problem then run
Tune at SP again if required. *Note: If control is disabled, running Pre-Tune at First Power-up (or immediately after a Reset to Default) automatically sets
the control to enabled.
5. Once Pre-Tune is complete it will disengage, and
the ‘TUNE’ notification ends. The length of time the
tuning takes to complete will vary from process to
process.
9.2 Running Tune at SP
1. Initial PID values. Tune at SP needs a reasonable
level of process stability to run. It is therefore recommended to set the initial PID values in the Control menu back to their default values: Proportional
Band to 10% of your chosen input range, Auto Reset (Integral) to 5.00 and Rate (Derivative) to 1.15
before using Tune at SP.
2. The Tune at SP can be activated via the Automatic
Tuning parameter in the Setup menu or the Advanced Configuration menu. It may also be activated via a Modbus command.
The message ‘TUNE’ is displayed whilst Tune at SP
is running.
3. Once Tune at SP is complete it will disengage, and
the ‘TUNE’ notification ends. The length of time the
tuning takes to complete will vary from process to
process
9.3 Tuning at SP Troubleshooting
Tune at SP will not engage, and a Tune Error message
will be displayed under the following conditions: 1)
There is a sensor break, 2) A setpoint ramp has been
set, 3) A Timer is running, 4) Control is Disabled. 5) The
current control mode is On-OFF 6) The controller is in
Manual mode.
Resolve the displayed problem then run Tune at SP
again if required.
If Tune at SP starts, but remains running indefinitely,
the cause is either the process value not achieving reasonable stability (±1% of span), or the control power
variation is too great (±10%).
To resolve this:
1. Check the PID values in the control menu were at
the defaults values (see above). If they were correct,
go to step 2. Otherwise, correct them and run Tune
at SP again.
2. If step 1 has not resolved the issue, observe the
displayed process value for >5minutes and noting
the highest and lowest values seen. Subtract the
lowest value from the highest to find the peak-to-
27
Page 34
peak deviation. Check the input span (Scale Range
Maximum minus the Scale Range Minimum) to see
if the it is >100 x the peak-to-peak deviation. If not,
increase the input span to more than this value, and
run Tune at SP again.
3. If this has not resolved the issue, double the current
PID terms (Proportional Band, Auto Reset and
Rate values), then run Tune at SP again.
4. In the unlikely event that the tuning still does not
complete continue from step 3.
9.4 Tuning at SP for Heat and Cool
Tuning at SP is possible for Heating or Cooling applications, but not for both Heat and Cool together. If you
have defined outputs for heating and cooling, Tune at
SP is not offered in the tuning menu. Instead use PreTune.

10 Digital Input Operation
Depending on your model, the digital input can be used
to perform one of the available functions as shown in
the table below.
High = Open contacts (and 2 to 24Vdc for the isolated
digital input).
Low = Closed contacts (and <0.8Vdc for the isolated
digital input).

When the instrument is turned on, a change in the digital input signal from High Low, or Low to High will
cause the function to change (unless it is already in the
state dictated by the signal change).
The keypad can also be used to change the status of
the same function via the relevant menu. The most
recent digital input or keypad instruction will be
implemented.
The digital input is “edge sensitive”, which
means that it only reacts to a detected
transition in the input state. The device
cannot detect a status change made
when it is turned off. It also means that
if it is in the “ON” state, but the current
condition of the unit is the “OFF” state
(either because a keypad instruction or
it has powered up that way) the digital
input would first have to be set first to
OFF and then ON again before it would
set the function ON.
However, on the Limiter model if the Digital Input is in
an “ON” state at power-up it gives a Reset signal. Once
powered up the Limiter model behaves the same way
to a transition.
29

Unit

Menu – “ON”

1. On start-up, the unit uses the Power-Up Action for
its initial control state. In this example, it starts in the
disabled condition.
2. Digital input signal changes from Low to High;
therefore, control becomes enabled. The Control
Enable parameter will say ON, when viewed from
the HMI (front panel).
3. The keypad on the HMI (front panel) menu is used
to change the control back to disabled, Control En-
able parameter = OFF.
4. The digital input changes state, going from High
to Low, but as the control is already disabled no
change is made.
5. Then the digital input goes from Low to High again,
re-enabling the control. The Control Enable parameter in the HMI also shows control is ON again.

11 Timer Feature
11.1 Timer Feature
The timer feature is only available on the Standard
model. It consists of a Delay Timer and an On Timer.
When the Timer Enable parameter is set to Disabled
the timer will not be used and the delayed start time
and on time are ignored. Note: If the setpoint has been
set to ramp, this will still be active, even if the timer is
Disabled.
The timer, control power down state and the power-up action have the following relationship:
When Enabled the timer will take control of the Setpoint as defined by the Delayed Start Time and On
Time parameters. Enabling the timer has no effect until
the controller is power cycled or the control is disabled
then re-enabled.

11.2 Delay, Ramp & Timer Diagram
The delay, ramp and soak is only available on the standard model.
1. From power-up, if control is in the enabled state, or
whenever control is changed from disabled to enabled, the unit delays process control (i.e. control is
still disabled) until the Delay Timer expires (time as
set by Delayed Start Time). If this is OFF, step 1 is
omitted.
2. Setpoint ramps from the current PV to the target
setpoint at Ramp Rate (‘RAMP’ alternating with the
current effective SP value indicates it is still ramping). If Ramp Rate is OFF the effective setpoint
steps directly to target setpoint.
3. After any Delay and/or Ramp completes, the setpoint ‘Dwells’ at the target value while the On-Timer
counts down (time set by On Time).
4. When the On Timer finishes the control switches off
(i.e. control is disabled). If the On Timer has been
set to OFF, step 4 is omitted, and control is maintained at the setpoint indefinitely.

12 Extrusion Model Only Features
12.1 Non-Linear Cooling Function
The initial cooling effect with water cooling can be
very strong when water first flows into a hot process.
Evaporation extracts significant amounts of heat energy making the effective cooling power disproportionally high at nominally low levels of cooling output.
This makes process control more difficult, particularly
if “over-cooling” during the transition from heating to
cooling causes the heating to be reactivated. Non-Linear Cooling can be used to counteract these effects by
applying the cooling more gradually at first.
To enable the Non-Linear Cooling function the Output
1, Output 2 or Output 3 Usage parameter needs to be
set to Non Linear Cooling.

Heat Power
12.2 Method
The cooling characteristic is altered so that the controller output is weak until approximately 70% of nominal
cooling demand. Beyond this level, the correcting variable rapidly rises to the maximum cooling allowed.
Cooling is inhibited entirely until the Minimum Cooling temperature has been exceeded. After that it turns
ON with fixed duration pulses (adjustable with Impulse
Length parameter). The OFF time between pulses is
varied to adjust the cooling effort, but is never off for
less than Minimum Off Time value whenever cooling is
active. This ratio limits the maximum effective cooling.
The maximum effective cooling is calculated as follows:
Impulse Length
Max Cooling= x 100%
Impulse Length + Minimum Off Time
The Non-Linear Adjust parameter can be reduced if the
corrective action is too severe by reducing the non-linearity of the effective output. See the examples below.

Non Linear Adjust = 900
Non Linear Adjust = 1

Page 40
12.3 Parameter Adjustment
Minimum Cooling
Cooling is enabled only above the temperature set because evaporation, with its associated cooling effect,
is not possible at temperatures below 100°C. Set this
>100, but it should be well below the normal operating
setpoint.
Note: In manual mode cooling is still possible below
this temperature.
Impulse Length
A fixed length for cooling pulses set by this parameter.
The ON pulses are this length for all cooling output values above 1% nominal cooling demand.
Relatively low values should be used, but remember that
the ratio of the Minimum Off Time vs Impulse Length
affects the maximum effective cooling (see above). Do
not allow this to limit cooling to the extent that insufficient cooling effect is available for the process.
The impulse length is also limited by the hardware (e.g.
the response time of your valve). Valves and electromechanical relays should not be switched to quickly.
Consult the device manual or check with your supplier
for suitable minimum settings.
Using these settings, and observe the transition
from heating to cooling. If there is a noticeable
over-reaction, where the cooling is still too strong,
increase the Non-Linear Adjust value until the effect is reduced to acceptable levels. If the transition
becomes too slow, with effective cooling unacceptably delayed, reduce the value set.
12.4 Soft Start Function
Soft Start is primarily intended to allow heaters to dry
out gradually at start-up condensation which can form
when the heaters are cold can cause damage if it evaporates too quickly.
Soft Start has its own setpoint, allowing a pre-defined
low-temperature dwell period which reduces the power
demand from the heaters, allowing moisture to evaporate more slowly before going to full working temperature. During this period, it also minimizes the heater-on
times by reducing the cycle time and limiting the PID
power demand.
Note: Soft Start does not limit the instantaneous current to the heaters when the output is on.
Activated by setting the parameters Soft Start Time
and Soft Start Setpoint.
Minimum Off Time
The “off” time between pulses is varied dependent
upon the PID cooling demand. The Minimum Off Time
is the minimum allowed “off” time (but note that below
1% of cooling demand, the output is disabled).
The time set is hardware-dependent (e.g. the response
time of your valve). Generally, it is best set to the lowest
value compatible with the output switching device, but
remember that valves and electromechanical relays
should not be switched to quickly. Consult the device
manual or check with your supplier for suitable minimum settings.
Remember that the ratio of the Minimum Off Time vs
Impulse Length affects the maximum effective cooling
(see above). Do not allow this to limit cooling to the
extent that insufficient cooling effect is available for the
process.
Non-Linear Adjust
This attenuates the cooling curve, and altering where
the output rate begins to increase more rapidly. The value can be reduced if the corrective action is too severe,
this reduces the non-linearity of the effective output.
To find an appropriate Non-Linear Adjust setting:
First set Minimum Cooling, Impulse Length and
Minimum Off Time to appropriate values (see
above), and initially set Non-Linear Adjust to 5. Use
Pre-Tune or manual tuning to adjust the controllers
PID settings to your process.
1. When powered up the unit will control to the Soft
Start Setpoint. The control cycle time is 1/4 of the
value entered (subject to the minimum possible
value of 0.5s) and the maximum power demand is
limited to the Heat Power Limit value (set in the
Control menu). The reduced cycle time is used during the soft start phase.
2. After reaching the Soft Start Setpoint the Soft Start
Time begins. The timer starts as soon as the PV is
equal to Soft Start Setpoint – 1. The Soft Start Setpoint is maintained until this time has elapsed.
3. When Soft Start Timer expires, the unit returns
to normal operation. It controls to the normal setpoint, the cycle time reverts to the value set and the
Heat Power Limit is no longer used.
Remember, when using the Soft Start
feature the Heat Power Limit is only
active from power-on and during the Soft
Start Time. It remains in use until the Soft
Start timer expires or all the time if no
Soft Start time is OFF.

13 Limiter Models
13.1 Introduction to the Limiter
Model
LM EX AL
The Limiter model has fixed output functions.
Depending upon which option is fitted in Output 3 it is
Alarm 2 or Retransmit PV.
Refer to the Information menu or check the product
label identify your version.
Output 1. = Limit
Output 2. = Alarm 1
Output 3. If Relay or SSR = Alarm 2 / If Linear = Re-
transmit PV
The Limiter LEDs have fixed functions: Limit, Exceed
& Alarm.
When the PV enters the Exceed condition both the Limit and Exceed LEDs turn ON. Going from the Exceed
condition back into the Safe condition the Exceed LED
will turn off but the Limit LED will stay latched until it
is reset. Remember the Limit output itself is energized
in Safe condition but de-energizes when in the Limit
condition.
Navigating is the same as the Standard and Extrusion
versions, see General Navigation & Editing, but for security, users cannot change parameter values such as
the Limit Setpoint in the Operator mode on the Limiter
model. These can only change values via the lock code
protected Setup or Advanced Configuration modes.
Warning & Error messages on the Limiter model are
similar to the Standard and Extrusion versions, with
the exclusion of control or tuning related messages. On
the Limiter, there is the additional pop-up alert Limit
Exceeded message if the process is beyond the limit
value set.
Please refer to the Warnings & Messages section.
The Annunciator alarm type, which can be selected for
Alarm 1 or Alarm 2, cannot be inhibited.
13.2 Limiter Modbus Communica-
tions
Please refer to the Commonly Used Modbus Addresses and the Limiter Modbus Addresses for the Modbus
register addresses.
See the Serial Communications for general communications information.
13.3 Limiter Digital Input
The Digital Input has only one function on the Limiter
model. There is no need for a configuration parameter
because it is always a Limit & Alarm Reset. Refer to the
Digital Input Operation section. However, in addition on
the Limiter model, if the Digital Input is in an Open state
at power-up it gives a Reset signal.

13.5 Limiter Output Latching
When an SSR drive or Relay output is configured to
‘latch’ it will remain on after the limit or alarm condition has cleared. The latch enable parameter, Output
Latching, needs to be ON for outputs you want to
latch.
Limiter Clearing Latched Outputs
The latch condition, shown by in the Latch State
screen, needs to be cleared either via a Modbus command, digital input or from the front panel.
To clear latches from the front panel, in the Latch State
screen, press then to select Yes.
Press to accept.
Limiter Start-up Latch
The parameter Startup Latch, is only present on the
limiter model. It determines how latching outputs behave when the unit is powered up. It is set individually
for each of the outputs (limit and/or the 2 alarms). The
three possible modes are as follows:
• Reset Latch: The latch state is not remembered
when the unit is powered off. The latch becomes
active again only if the associated limit / alarm state
is present at or after power-on.
Output Latched
Latch set, but output
not Latched
– Latch not set
• Always Latch: The instrument will always power on
with the chosen output in the latched state, even if
the associated limit or alarm is not active.
• Last Latch: The latch state is remembered on
power down. Any output that was latched on power
down it will still be latched when power is restored,
even if that limit or alarm is no longer active.
Note: If a limit or alarm state exists at power-up,
previously unlatched outputs always activate immediately, no matter how the Start-up Latch has
been set.
Limiter Sensor Break Detection
If a “Sensor break” is detected on the Limiter model,
this always triggers the Limit exceed condition, place
the process into a safe state. Correct the input problem, then unlatch the limit output to resolve this.
Limiter Output 3 – Linear, Relay or SSR drive
• If the linear output is fitted to Output 3 on the Limiter
model, it can only be used for a PV re-transmit function.
• If a relay or SSR drive is fitted in Output 3 then it is
fixed as Alarm 2.

14 Configuration Software
14.1 Introduction
The ChromaTemp Configurator Software Program is
available at no charge from the Chromalox website:
www.chromalox.com. It facilitates the cloning of multiple controllers and fast parameter file uploads and
downloads to and from the controller or PC. It also
comes with a Setup Wizard which covers the most basic wiring, input type and programming requirements.
14.2 Connectivity Requirements
In order to use the ChromaTemp Configuration Software, you must connect to a PC in one of two ways:
1. Use the RS485 control terminals and PC connection
(controller must have the RTU/RS485 feature) or 2. Use
the Chromalox Universal Converter & ChromaTemp
Configurator Cable.
1. The Universal converter comes with a cable which
connects to the USB port on your PC.
2. The ChromaTemp Cable connects to a dedicated
port on the bottom of your DIN Controller. (See connection details below)
The ChromaTemp dedicated configuration port
is very similar to a micro USB socket. It should
never be directly connected to a standard USB
port or USB charger. Use of this socket requires the Universal Converter to ChromaTemp
Controller cable which is available from Chromalox. See the Accessories on the DIN Controller Order Table.
44
Page 51
14.3 Installing & Accessing the Configuration Program
Locate the program on the Chromalox website and
install it to a known location on your PC. You may
choose to have a quick launch icon located on your
desktop for fast access. After the program is loaded,
locate the quick launch icon and open the program.
14.4 Getting Started
You will be presented with the ChromaTemp Configurator Option Selection window. You may accept the
model that is presented to you or modify the outputs,
options and supply voltage or Read (upload) the op-
To read the settings from a DIN controller, the unit must be
powered up and properly connected to your compter via the
Universal Converter. (See 12.2 above)
tions and settings from an existing DIN controller. If
you wish to accept the Model presented to you, simply select [ OK ] to and proceed to the Section 12.7
Navigating The Configurator.
45
Page 52
14.5 Troubleshooting the ChromaTemp Configurator
When connecting the controller to the PC for the first
time, Windows will attempt to load the device drivers.
In some cases, you may need to direct this Windows
function to the file location of your ChromaTemp Configuration Program.
When attempting to run the program the first time, you
may need to shut down/restart the Configuration Program.
You may receive this Timeout Error message if:
A. The connection is not correct or,
B. The device files have not been loaded or,
C. The USB connection tree has not yet been popu-
lated.
You may receive this USB Device Not Recognized
window. This occurs when your controller is connected
but the computer has not completed the installation of
the necessary device drivers or it has not completed
populating the USB connection tree.
Be patient. Verification of the drivers and populating
the COM ports and USB connection tree may take several minutes.
If you are still having connectivity/program recognition
errors, you may wish to investigate your Windows De-
vice Manager. Ensure that you have no warning symbols.
In this example, the COM7 is the Communications Port
to which the Universal Converter is attached. Select
[OK].

14.6 Getting Started
14.6 Getting Started (continued)
We are back at attempting to Read all Parameter Settings and Model Features from an existing device.
The controller is properly connected and the converter
is recognized by your PC.
(See 12.5 for troubleshooting suggestions).
From the Confirm Settings to Connect window,
choose which communication port (Configuration Port
or RS485 Port) and the respective Port Settings (COM1
or COM7 for example). Select [ OK ]
The progress of the device reading will be displayed
in the Communications Progress window. The device
reading should take approximately 10 seconds.
Upon a successful reading from your device, you will
see that the Outputs and Options displayed in the
ChromaTemp Configurator Option Selection window
are now the same as your controller.
Parameter value changes may be made within the
Configuration Software program. These changes may
be saved to a file, downloaded to the controller, or hard
copy printed for review.

If you are working online with your instrument, press
, then check and adjust Units’ Communication Port, the PC COM port number, and if using
RS485, enter the correct Address, Baudrate, Databits
and Parity (as currently setup in your instrument).
Then press to read in your 1020 Controller
hardware options.
This step reads in the hardware settings
from the connected unit but not the parameter settings.
Read in Parameter Configuration
Before reading in the parameters, first upload the hardware options (see above).
Then press to read in the current settings from
the unit.
Make Configuration Changes
Edit the configuration to your requirements.
Write to Unit
Press to download your new configuration to
the unit.
Save Changes to File
Press to save any changes to a file if you wish to
use it later.
Loading in Older Configuration Files
The ChromaTemp configurator may give a warning
when loading in a file from older versions of the configurator.
If you open this file you need to consider that the Unit
Information-Details section may not be complete or
correct.
Opening files in older versions of the configurator will
not give a warning message but can give misleading
information in the Details.
For example, see screenshot where the DoM is July
2014.

Firmware and Language Updating
If advised by the factory or your authorized supplier, you
can upgrade the firmware in the connected instrument
by pressing . Set the communications parameters
(see above), then press the but-
ton.
Follow the on-screen instructions, ensuring you select
the correct type and version of firmware file (*.s19) for
your 1020 Controller type.
Model Firmware Name
Standard V227E_Encrypt.s19
Extrusion V227F_Encrypt.s19
Limiter V227G_Encrypt.s19
If you are uploading language files (1020 Controller
only) the version needs to match the firmware.

15 Serial Communications
MODBUS
SLAVE
INSTRUMENT
15.1 Supported Protocol
The unit supports Modbus RTU protocol through the
RS485 interface.
For a complete description of the Modbus protocol refer
to the description provided at http://www.modbus.org/
15.2 RS485 Configuration
The RS485 address, bit rate and character format are
configured via the front panel from the Communications Sub-menu.
Data rate: 4800, 9600 (default), 19200 or 38400 bps
Parity: None (default), Even or Odd
Device Address: 1 to 255 - See RS485 Device Ad-
dressing
For successful communication the
master device must have matching
communications settings.
15.3 RS485 Device Addressing
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.
Except for globally addressed broadcast messages
sent to device address 0, the instrument ignores Modbus queries from the master that do not match the
address that has been assigned to it. These global
queries are processed when received but no response
messages are returned.
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.
Three character times is approximately
0.75ms at 38400 bps, 1.5ms at 19200 bps,
3ms at 9600 bps and 6ms at 4800bps.
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.
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.
The standard MODBUS RTU CRC-16 calculation employing the polynomial 216+215+22+1 is used.

Write Multiple Holding
Registers
Read current binary value of specified number of parameters at
given address.
Up to 64 parameters can be accessed with one query.
Writes 2 bytes to a specified word address.
Writes up to 253 bytes of data to the specified address range.
15.6 Function Descriptions
The following is interpreted from the Modbus Protocol Description obtainable from http://www.modbus.org/.
In the function descriptions below, the preceding device address value is assumed, as is the correctly formed twobyte CRC value at the end of the QUERY and RESPONSE frames.
15.7 Function 03 / 04 - Read Holding/Input Registers
Reads the current binary value of data at the specified word addresses.
Query
Function Address of 1st Word Number of Words
03/04 HI LO HI LO
Response
Function Number of Bytes First Word Last Word
03/04 n HI LO HI LO
In the response, the “Number of Bytes” ‘n’, indicates the number of data bytes read from the instrument. E.g. if 5
words are read, the count will be 10 (A hex). The maximum number of words that can be read is 64. If a parameter
does not exist at one of the addresses read, then a value of 0000h is returned for that word.
Function 06 – Write Single Register
Query
Function Diagnostic Code Value
06 HI = 00 LO = 00 HI LO
Response
Function Sub-Function Value
06 HI = 00 LO = 00 HI LO

This Glossary explains the technical terms and parameters used in this manual. The entry type is also shown:
Actual Setpoint
Actual Setpoint is the current effective value of the
Setpoint. This will be different to the target value of the
setpoint if it is currently ramping. The actual setpoint
s rises or falls at the ramp-rate set, until it reaches the
target Setpoint value.
Also refer to Active Setpoint, Setpoint, Setpoint Ramp
Enable and Setpoint Select
Alarm Hysteresis
An adjustable band on the “safe” side of an alarm
point, through which the process variable must pass
before the alarm will change state, as shown in the diagram below.
Also refer to Alarm Operation
Alarm Operation
The different alarm types are shown below, together
with the action of any outputs.

Alarm, Deviation Alarm, Latching Relay, Logical Alarm
Combinations, Loop Alarm, Process High Alarm and

Page 77
Alarm Inhibit
Inhibits an alarm at power-up or when the controller
setpoint is changed, until that alarm would become
inactive. The alarm operates normally from that point
onwards.
Note that on the Limiter there is a similar function called
Start Up Inhibit which is applicable only at power up,
not when the limit setpoint is changed.
Also refer to Alarm Operation.
Automatic Reset (Integral time)
Used to automatically bias proportional control
output(s) to compensate for process load variations. It
is adjustable in the range 1 seconds to 99 minutes 59
seconds per repeat and OFF Decreasing the time increases Integral action. This parameter is not available
if the primary output is set to On-Off.
Also refer to Heat Proportional Band, Cool Proportional
Band, Rate, and Tuning.
Auto-Tune
Refer to Pre-Tune and Tune at Setpoint.
Band Alarm Value
Refer to Alarm Operation.
Bumpless Transfer
A method used to prevent sudden changes to the output power level when switching between automatic
and manual control modes. During a transition from
automatic to manual, the initial Manual Power value is
set equal to the previous automatic mode value. The
user then adjusts as required.
During a transition from Manual to Automatic, the initial Automatic Power value is set to equal the previous
manual value. The correct power level is gradually applied by the control algorithm at a rate dependant on
the integral action (see Automatic Reset). Since integral
action is essential to Bumpless Transfer, this feature is
not available if Automatic Reset is turned off.
Also refer to Automatic Reset (Integral time) and Manual Mode.
Calibration - 2 Point (High/Low PV
Offset)
Two-point calibration uses two separate points of reference, usually at the process high and low operating
limits, to determine the required offsets. These offsets
are used to rescale all readings over the full range of the
controller minimizing inaccuracies in the input reading.
See the User Calibration section.
Also refer to Calibration - Single Point (PV Offset) , Input Span & Span and Process Variable.
Basic Setpoint Control
When Basic Setpoint Control is enabled the user can
only change the set point or the Auto/Man power from
the User mode screen. To change other settings the
user must enter the Advanced Configuration Mode.
The parameter to enable/disable Basic Setpoint Control is in the Display menu.
Bias (Manual Reset)
Used to manually bias the proportional output(s) to
compensate for process load variations. Bias is expressed as a percentage of output power, and is adjustable in the range 0% to 100% (for Heat or Cool
outputs alone) or -100% to +100% (for both Heat and
Cool Outputs). This parameter is not applicable if the
primary output is set to ON-OFF control mode. If the
process settles below setpoint use a higher Bias value to remove the error, if the process variable settles
above the setpoint use a lower value. Lower Bias values also help to reduce overshoot at process start up.
Also refer to ON/OFF Control.
Calibration - Single Point
(PV Offset)
Single point calibration uses one point of reference,
usually set at a critical process operating value, for the
required calibration offset. This offset is applied to all
measurements across the input span. See the User
Calibration section.
This can be used to compensate for errors in the displayed process variable. Positive values are added to
the process variable reading, negative values are subtracted, so MUST be used with care. Incorrect use
could cause the displayed value not to show the actual
process value.
Also refer to Calibration - 2 Point (High/Low PV Offset),
Input Span & Span and Process Variable.
Control Type
In the Out 1, Out 2 and Out 3 parameters to set the
direction of output increase/decrease vs the movement
of the process. Heat is reverse acting, Cool is direct
acting (e.g. cooling output in-creases when the temperature rises).
Refer to Heat Proportional Band, and Cool Proportional
Band.
71
Page 78
Controller
An instrument that can control a process, using either
PID or On-Off control methods. Alarm outputs are also
available, as are other options and Serial Communications.
Refer to Alarm Operation, Limit Controller, On-Off Control, and Serial Communications.
Cool Proportional Band
The Cool Proportional Band is only applicable when a
Cool Output is used. It is the portion of the input span
over which the Cool Output power level is proportional
to the process variable value. Adjustable in input units’
equivalent to 0.5% to 999.9% of span (zero = On-Off
control). The Control action for the Cool outputs is direct acting.
Refer to Control Type, On-Off Control, Heat Proportional Band and Tuning.
Heat Proportional Band
The Heat Proportional Band is only applicable when a
Heat output is used. It is the portion of the input span
over which the Heat Output power level is proportional
to the process variable value. Adjustable in input units’
equivalent to 0.5% to 999.9% of span (zero = On-Off
control). The Control action for the Heat outputs is reverse acting.
Also refer to Control Type, On-Off Control, Cool Proportional Band, and Tuning.
Input Filter Time
Used to filter out extraneous impulses (“noise”) on the
process input. The filtered PV is used for all PV-dependent functions (display, control, alarm etc). The time
constant is adjustable from 0.0 seconds (off) to 100.0
seconds in 0.5 second increments.
Also refer to Process Variable.
Cycle Time
For time-proportioning outputs, cycle time is used to
define the time over which the average ON vs. OFF
time is equal to the required PID output level. The range
of values is 0.1 to 512 seconds in 0.1s steps. Shorter
cycle times will give better control, but at the expense
of reduce life when used with an electromechanical
control device (e.g. relays or solenoid valves).
Also refer to Time Proportioning.
Deadband
Refer to Overlap/Deadband.
Derivative
Refer to Rate.
Deviation Alarm
Refer to Alarm Operation.
Input Range and Input Span
The Input Range is the overall non-restricted range as
determined by the Type parameter in the input menu.
The Input Span (or Scaled Range) is the limited working range set by the upper and lower limits in the input
menu. The input span is used as the basis for calculations that relate to the span of the instrument (e.g.
controller proportional bands).
Also refer to Scale Range Lower and Scale Range Upper.
Limit Controller
A protective device that can shut down a process at
a pre-set Exceed Condition, to prevent possible damage to equipment or products. They are recommended
for any process where product or equipment damage
might occur, or if it could become hazardous under
fault conditions.
Heat or Cool Output Power Limits
Used to limit the power level for heating or cooling to
protect the process or heaters. Adjustable from 0% to
100%. This parameter is not applicable if the primary
output is set for On-Off control.
Also refer to On-Off Control.
72
Page 79
Loop Alarm
This is a special alarm, to detect problems with the
control feedback loop. It continuously monitors the
process response to the control output.
If control is at the maximum or minimum limit (0% or
100% for single Heat or Cool output and -100% &
+100% for dual Heat and Cool outputs), an internal
timer starts. If the process variable is not moved in the
expected direction by a predetermined amount ‘V’ after
time ‘T’ has elapsed, the loop alarm becomes active.
Only when the process has moved by “V”, or when the
output is no longer at the limit, does the loop alarm
deactivate.
*If the heat or cool power limits are less than 100% the
limited value is used as the maximum. E.g. if the limit is
70%, the timer begins at 70%.
For PID control, the loop alarm time ‘T’ is always twice
the Automatic Reset (Integral) parameter value. For
On-Off control, a user defined value for the Loop Alarm
Time parameter is used.
The value of ‘V’ is dependent upon input type. For temperature inputs, V = 2°C or 3°F. For linear inputs, V = 10
least significant display units.
Correct operation of the loop alarm depends upon
reasonably accurate PID tuning. The loop alarm is automatically disabled during manual control mode and
during automatic tuning.
Also refer to Manual Mode, On-Off Control, and Process Variable.
Manual Mode
If manual mode is selected from operator mode (if enabled), via the digital input or serial comms, the PID
algorithm is suspended. It must therefore be used with
care, because the controller is no longer in control of
the process. The operator must maintain the process
at the required value, by adjusting the % power output
value.
In Manual mode, the display shows the current process value as normal, but the setpoint is replaced with
the % output power. This value may be adjusted using keypad, between 0% to 100% for controllers using
Heat control only, and -100% to +100% for controllers
using dual Heat and Cool control.
Switching between automatic and manual modes is
achieved using bumpless transfer.
Note: Manual power is not limited by the power output
limits.
Also refer to Bumpless Transfer, and Heat/Cool Output
Power Limit.
Master & Slave
The terms master & slave are used to describe the controllers in applications where one instrument controls
the setpoint of another. The master controller (e.g. a
profile controller) transmits a setpoint to 1020 using
RS485 serial communications (analog signals cannot
be used because 1020/1030 does not have a remote
setpoint input option). 1020/1030 cannot act as a Master.
Also refer to Serial Communications and Setpoint
On-Off Control
On-Off control mode, the output(s) turn on or off as the
process variable crosses the setpoint just like a home
heating thermostat. Some oscillation of the process
variable is inevitable with On-Off control.
On-Off control is enabled by setting the corresponding
proportional band(s) to Off (zero). It can be assigned to
the Heat output alone (Cool output not present), Heat
and Cool outputs or Cool output only (with the Heat
Output set for time proportional).
Also refer to Heat Proportional Band, Cool Proportional
Band, On-Off Differential, Setpoint and Time Proportioning Control.
On-Off Differential (Hysteresis)
A switching differential, centred about the Setpoint,
when one or both control outputs have been set to OnOff. It is adjustable from 0.1% to 10.0% of input span,
entered in display units.
Relay chatter can be eliminated by proper adjustment
of this parameter, but larger values do increase amplitude of process oscillations.
Also refer to Input Range and Input Span and On-Off
Control.
Overlap/Deadband
Defines the portion of the Heat and Cool proportional
bands over which both outputs are active (Overlap), or
neither is active (Deadband). It is set in display units,
within a range of -20% to +20% of the sum of the two
proportional bands (e.g. If Heat PB is 3 and Cool PB is
2, their sum is 5, and ±20% is -1 to +1). Positive + values = Overlap, Negative - values = Deadband.
If the Cool Output is set for On-Off, this parameter
moves the Differential band of the Cool Output to create the overlap or deadband. When Overlap/Deadband
= 0, the “OFF” edge of the Cool Output Differential
band coincides with the point at which the Heat Output
= 0%. ).
Also refer to Differential, On-Off Control, Heat Proportional Band and Cool Proportional Band.
73
Page 80
PID Control
Proportional Integral and Derivative control maintains
accurate and stable levels in a process (e.g. temperature control). It avoids the oscillation characteristic of
On-Off control by continuously adjusting the output to
keep the process variable stable at the desired Setpoint.
Also refer to Automatic Reset, Controller, Manual
Mode, On-Off Control, PI Control, Heat Proportional
Band, Process Variable, Rate, Cool Proportional Band,
Setpoint and Tuning
Pre-Tune
Starting with the load cool*, Pre-Tune disturbs the process start-up pattern, so that the PID values are calculated before the setpoint is reached.
During Pre-Tune, the controller outputs full Heat Power
until the process value has moved approximately halfway to the Setpoint. At that point, power is removed
(or full Cool Power with dual control), thereby introducing a process oscillation. Once the oscillation peak has
passed, the instrument calculates the PID tuning terms:
proportional band(s), automatic reset and rate. Normal
PID control operation begins using these calculated
values, and Pre-Tune automatically disengages.
*Ideally the Tune program should be used when the
load temperature is close to ambient.
Care should be taken to ensure that any overshoot is
safe for the process and if necessary tune at a lower
setpoint.
Pre-Tune will not engage if either Heat or Cool outputs
on a controller are set for On-Off control, the controller is set to Manual, during Setpoint ramping, or if the
process variable is less than 5% of the input span from
the Setpoint. Refer to the Automatic Tuning section for
further details.
Also refer to Automatic Reset, On-Off Control, Input
Span, PID, Heat Proportional Band, Process Variable, Rate, Cool Proportional Band, Setpoint, Setpoint
Ramping and Tuning.

Process Variable (PV)
Process Variable is the signal measured by the primary
input. The PV can be anything that can be converted
into a compatible electronic signal. Common types are
Thermocouple or PT100 temperature probes, %RH or
pressure etc. from transducers that convert them to
linear dc signals (e.g. 4 to 20mA). These signals are
scaled into engineering units using the Scale Range
Lower Limit and Scale Range Upper Limit parameters.
Also refer to Input Range & Span, Scale Range Lower
Limit and Scale Range Upper Limit.
Rate (Derivative)
Rate is adjustable from 0 (OFF) to 99 minutes 59 seconds. It defines how the control output responds to the
rate of change in the process. Rate is not available in
On-Off.
Also refer to On-Off Control, PID, Process Variable and
Tuning.
Reset / Integral
Refer to Automatic Reset.
Reverse Acting
Refer to Direct/Reverse Action of Control Output
For thermocouple and RTD inputs, this parameter is
used to reduce the effective range of the input. All span
related functions, work from the trimmed span. The parameter can be adjusted within the limits of the Input
Range selected. It is adjustable to within 100 degrees
of the Scale Range Upper Limit.
Also refer to Input Range & Span, Process Variable and
Scale Range Upper Limit.
Serial Communications Option
A feature that allows devices such as PC’s, PLC’s or a
master controller to read or change an instrument’s parameters via a communications link. 1020 & 1030 Controllers optionally support RS485 Modbus RTU communications as a factory fitted option, in addition to the
front configuration port.
Also refer to Controller, Indicator, Master & Slave and
Limit Controller.
Setpoint
The target value at which a controller will attempt to
maintain the process by adjusting its power output
level. Setpoints can be adjusted between the Setpoint
Upper Limit and Setpoint Lower Limits.
Also refer to Limit Setpoint, Process Variable, and Setpoint Upper & Lower Limits
Scale Range Maximum
For linear inputs, this parameter is used to scale the
process variable into engineering units. It defines the
displayed value when the process variable input is at
its maximum value. It is adjustable from -1999 to 9999
and can be set to a value less than (but not within 100
units of) the Scale Range Lower Limit, in which case
the sense of the input is reversed.
For thermocouple and RTD inputs, this parameter is
used to reduce the effective range of the input. All span
related functions work from the trimmed input span.
The parameter can be adjusted within the limits of the
Input Range selected. It is adjustable to within 100 degrees of the Scale Range Lower Limit.
Also refer to Input Range & Span, Process Variable and
Scale Range Lower Limit.
Scale Range Minimum
For linear inputs, this parameter can be used to display
the process variable in engineering units. It defines the
displayed value when the process variable input is at
its minimum value. It is adjustable from -1999 to 9999
and can be set to a value more than (but not within 100
units of) the Scale Range Upper Limit, in which case
the sense of the input is reversed.
Setpoint Upper Limit and Setpoint
Lower Limit
The maximum and minimum values allowed for setpoint adjustments. Set as required to prevent the process going too high or low. Setting both limits to the
same value locks the setpoint at that value.
The adjustment range for Setpoint Upper Limit is between current Setpoint and Scale Range Maximum.
The value cannot be moved below the current value of
the Setpoint.
The adjustment range is between Scale Range Lower
Limit and current Setpoint. The value cannot be moved
above the current value of the Setpoint.
Also refer to Scale Range Lower Limit, Scale Range
Upper Limit and Setpoint
Ramp Rate
The rate at which the actual effective setpoint value
moves towards its target value, when the Setpoint is
adjusted. With ramping in use, the initial value of the
actual Setpoint at power up, enabling control or when
switching back to automatic mode from manual control, is 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.
75
Page 82
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. If the setpoint is
changed controller attempts to follow at the predefined
ramp rate until the new setpoint is reach.
Also refer to Actual Setpoint, Manual Mode and Setpoint.
Solid State Relay (SSR)
An external device manufactured using Silicone Controlled Rectifiers, which can be used to replace mechanical relays in most AC power applications. 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. 1020 optional SSR Driver outputs
give time-proportioned 10Vdc pulses, which causes
conduction of current to the load when the pulse is on.
Also refer to Cycle Time and Time Proportioning Control.
Solenoid Valve
An electro-mechanical device to control gas or liquid flow. It has two states, open or closed. Typically,
a spring holds the valve closed until current passes
through the solenoid coil, forcing it open. Standard
Process Controllers with Time Proportioned outputs
are used to control solenoid valves.
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). The controller output opens the
valve when the process requires additional heat (high
flame).
Time Proportioning Control
This type of control can be used with electrical contactors, Solid State Relays or valves whenever Relay or
SSR Driver outputs are used for either primary (Heat)
or secondary (Cool) 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. The control algorithm determines the ratio of
time (on vs. off) to achieve the level of output power
required to correct any error between the process value and Setpoint. E.g. for a 32 second cycle time, 25%
power demand would result in the output turning on for
8s, then off for 24s.
Also refer to Cycle Time, PID, Heat Proportional Band,
Process Variable, Cool Proportional Band, Setpoint
and SSR.
Tuning PID
PID Controllers must be tuned to the process for them
to maintain optimum control. Adjustment is made to
the tuning terms either manually, or by using the controller’s automatic tuning facilities. Tuning is not required if the controller is configured for On-Off Control.
Also refer to Automatic Reset, Cool Proportional Band,
Heat Proportional Band, ON-OFF control, PID, PreTune, Rate and Tune at Setpoint.
Tune at Setpoint
This automatic tuning method can be used if Pre-Tune
cannot to run, because the current process temperature is too close to the target setpoint.
Tune at SP is activated via the Setup or Advanced Configuration menus. It can also be activated via the Digital
Input or a Modbus command. It works by waiting for
the process to “line-out” (approximately stable), then
adds a pulse to the control output to cause a small
process disturbance. This disturbance is analyzed to
establish the correct PID tuning terms for the application – see below.
The message ‘TUNE’ is displayed whilst Tune at SP is
running. The ‘TUNE’ notification ends when the tuning
is complete.
Tune at Setpoint will not engage, and a Tune Error message will be displayed if:
1). There is a sensor break
2). A setpoint ramp has been set
3). A Timer is running
4). Control is Disabled
5). The current control mode is On-OFF). The controller
is in Manual mode.
If you have defined outputs for heating and cooling,
Tune at SP is not offered in the tuning menu. Instead
use Pre-Tune.
76
Page 83
Running Tune at Setpoint from
Automatic Control
It is important to set Scale Range Maximum and Scale
Range Minimum correctly before tuning, Also, because
Tune at SP needs a reasonable level of process stability to run, it is recommended to set the initial PID values
in the Control menu back to their default values. See
the Automatic Tuning section for further information.
1. Activate Tune at SP.
2. When Tune at SP begins, the controller carries out a
“steady state estimation”. It waits until the process
has achieved reasonable stability (±1% of span &
max control power variation ±10)% for 5 minutes.
3. After 5 minutes of stability (see T0 below) the Pulse
response evaluation is carried out.
A “power pulse” is applied that reduces the current
control power by -20% (except if the current power
is already 20% or less, when a positive +20% power pulse is applied instead).
4. The power pulse is maintained until the process responds by 1% of span (see T1 below). E.g. falling by
1% if the power pulse was negative, or rising if the
pulse was positive.
5. The 20% pulse is removed, returning the power to
the value just before T0.
The process will continue to its maximum deflection,
and returns towards the original value.
6. The controller notes the time taken to recover
0.15% of span, then waits for the recovery to reach
0.3% (see T2 and T3 below) before using the pulse
response deflection and the time T3 - T2 to calculate new PID terms.
Note: The time tuning takes to complete will vary from
process to process.

Heat Proportional Band, ON-OFF control, PID, PreTune, Rate and Tuning.
