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.
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.
Ensure there is adequate air flow inside the panel to prevent overheating.
This bus connection links up the optional RS485 communications connections without extra wiring but does not supply power.
11
2 Electrical Installation
The installation should be only performed by technically competent personnel.
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.
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).
2.3 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
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.
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
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.
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.
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.
2.7 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
A USB PORT.
A configuration socket to USB adaptor can be obtained from your supplier.

3 Powering Up
ENSURE SAFE WIRING PRACTICES HAVE BEEN
FOLLOWED. WHEN POWERING UP FOR THE
FIRST TIME, DISCONNECT THE OUTPUT CON-
NECTIONS.
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.)
3.2 First Power Up or Factory Default
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.
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.
3.1 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.
3.3 Auto-Tune
The controller can be auto-tuned from the Setup Mode.
1. Pre-tune
2. Auto-tune at setpoint
You must complete the Setup by cycling through all of the parameters before using the device for the first time.
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.
This is configurable in the Advanced Configuration, in the Display submenu, parameter Screen Timeout. Any key press turns the display back on.

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.
3.9 Use of the Controller for Non-
Temperature 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.
3.7 Returning to Operator Mode
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
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 Calibration Low PV value.
b. Enter an equal, but opposite value to the observed 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 observed error as the Calibration High Offset to correct the error at the high point.
Calibration High Offset

Process 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.
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.
24
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.
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.
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).
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 (200 Ω 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
2. Press and hold the button, whilst the instrument is powering up, until the display shows the screen starting with mV. Be patient, may take approximately 30 seconds.
3. In the calibration phase menu displayed, highlight mV from the list.
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.
4. With mV selected, press . The following screen will appear:
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.
5. Press . You should see the messages Starting
Calibration, followed by Calibration in Progress.
A dot moves across the display to show the progress.
6. If the input is wrongly connected or an incorrect signal is applied the calibration will be aborted and the display will show Calibration FAIL. The previous calibration value will be retained.
25
7. If the calibration was successful, the display shows
Calibration PASS.
8. To clear the Pass or Fail pop-up press and .
9. Now press and to return to the calibration menu.
From here either select another calibration phase, or press & again to return to the operator screen.
When you have completed the required phases, press
& to exit back to the operator screen.
The Calibration Mode automatically exits if there is no button activity for five minutes.
8.7 Calibrating Other Input Types
The 50mV calibration must be carried out first. After this, you can select the other types in turn. The other calibration phase procedures are similar to the mV phase above, but ensure that the correct input signal and connections are used – see the wiring section for connection details.
8.8 Calibration Input States
Each input can have one of three states:
Description State Shown

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 Re-
set (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
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 Pre-
Tune.

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).

*Limit and Alarm outputs only reset if the limit exceed and/or alarm conditions are no longer present.
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
Below is an illustration of digital input and keypad use. The example is for the Control Enable function. Other functions behave in a similar way.
Unit

HMI
Menu – “ON”
Menu – “OFF”
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.
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.
The timer, control power down state and the power-up action have the following relationship:

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.

Description

The minimum “Off” duration with non-linear cooling
Adaptation of characteristics of the non-linear cooling
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.
32
Non Linear Adjust = 900
Non Linear Adjust = 1
33
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.
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.
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.
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
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.
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.
13.2 Limiter Modbus Communications
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.
Output 1. = Limit
Output 2. = Alarm 1
Output 3. If Relay or SSR = Alarm 2 / If Linear = Retransmit 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.
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.
• 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 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.
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
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 options 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.
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)
45
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.
Be patient. Verification of the drivers and populating the COM ports and USB connection tree may take several minutes.
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 populated.
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].
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.
46
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).
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.
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 ]
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.
47
14.7 Navigating the Configurator
File Toolbar
The File Toolbar contains several file-related function icons:
Open a previously saved configuration file via Windows Explorer
Save a new configuration file in Windows Explorer
Hard copy printout of all parameter settings
Opens the Option Selection window
Opens the Setup Wizard (See Section 12.8 below)

15 Serial Communications
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 Addressing
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.
For successful communication the master device must have matching communications settings.
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.
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.
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.

18 Glossary
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.

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.
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.
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.
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) , In-
put 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
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.
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 Pro-
portional Band, and Tuning.
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.
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.
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.
Deadband
Refer to Overlap/Deadband.
Derivative
Refer to Rate.
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.
Deviation Alarm
Refer to Alarm Operation.
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
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.
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 On-
Off. 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.
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.
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
74
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.
PV High Alarm Value
Refer to Alarm Operation.
PV Low Alarm Value
Refer to Alarm Operation.
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.
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.
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.
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.
Reset / Integral
Refer to Automatic Reset.
Reverse Acting
Refer to Direct/Reverse Action of Control Output
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 Set-
point 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
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.
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, Pre-
Tune, Rate and Tune at 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.
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
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, Pre-
Tune, Rate and Tuning.
