1. INTRODUCTION
In addition to the 1/16 DIN (48 x 48 mm) design, the UNICONT PM universal controller family is characterized by
easy setpoint adjustment and easy programming. The universal analog PID controller is suitable for processing
signals from Pt100 resistance thermometers, various thermocouples, and transmitters with a 4…20 mA
and 0…10 V DC, 0…5 V DC, 1…5 V DC, 0…100 mV DC signal. The control output can be a relay, a continuous
0…20 mA or 4…20 mA current signal, or an output suitable for operating an SSR (solid-state relay). The self-
learning autotuning (AT) mode helps users determine PID parameters. The device provides automatic wire
compensation for the Pt100 input signal and automatic cold junction compensation for the thermocouple input
signal. Some PM–500 series members are also capable of RS485 communication.
The UNICONT PM–500 enables more efcient control with a super-fast 50 ms sampling cycle and ±0.3% display
accuracy. Moreover, it supports a variety of control modes, including simultaneous control of heating and cooling
and automatic/manual control and communication functions.

Ally types have colored connection points. Other connection point types depend on the particular variant.
Important information for proper use:
– The digital input is not electrically isolated from internal circuits, so it must be insulated if it is connected
to another circuit.
– Make sure that the connection polarity of the temperature sensor or analog input is correct.
– Make sure the polarity of the power supply is correct.
–Do not swap the output and input terminals.
–For thermocouple sensors, use a compensation cable with the same specifications as the input sensors.
Using an extension cord of different specifications and/or materials makes temperature sensing less
accurate. For more reliable operation, choosing a high-grade compensation cable is recommended.
–Do not place sensor wires near AC wires.
– Do not attach communication cables to the AC power cord. Use only twisted-pair wires for communication
cabling. The length of the communication cable must not exceed 800 meters.
5. PROGRAMMING

5.2 STARTUP
When energized, the display will ash for one second, at which point all display sections will illuminate. Then the
hardware ID code and the input sensor type will ash twice, and the unit will switch to RUN mode. If ‘Open’ is
displayed, there is no source or there is a contact error on the universal input.
In RUN mode, the current temperature or the value provided by the sensor is displayed.
The parameters in each group are related to each other, so please follow the parameter order below.
Parameter group 3 [PAR3] → Parameter group 4 [PAR4] → Parameter group 5 [PAR5] →
Parameter group 2 [PAR2] → Parameter group 1 [PAR1] → SV Setting [SV]
Note: Changing the parameters of parameter group 3 can sometimes restore other related parameters. Always check that
such parameters are not affected.
5.3 INPUT SETTINGS [PAR3 →IN-T]
For normal operation, the universal input must rst the universal input must be set in ‘Setting’ mode. Then the
input type must be selected according to table 5.3.1 Input types. Default setting: KCaH.

Note: If the input specication is changed, the upper / lower limits of the SV will be automatically set to the maximum/
minimum values of the new specication for the temperature sensors. For analog inputs, it sets the analog upper/lower
input values to the max/min temperature range and the SV upper/lower limits to the upper/lower scale values. Therefore,
the settings need to be recongured.
5.3.2 Sensor Temperature Unit
When the input temperature sensor is selected, the [PAR3 - UNIT] can be set to display the desired unit (°C, °F).
However, this parameter is not displayed when an analog input is selected. The default unit is °C
When analog input is selected, it is possible to specify the unit [PAR3 - dUNT] (°C, °F,%, OFF). When OFF is
selected, the displayed unit is not specied. The LED unit display does not turn on. The default setting is %.
5.3.3 Analog Input Scale Value Settings
By selecting the analog input, the analog input range (upper / lower input limits) and the display scale (upper /
lower scale limits) within the selected input range can be set.
For analog input, ±5% of the set upper / lower limit is extended. The analog output is also expanded by comparing
the input value. (Using a ±5% extension for a temperature sensor input within the temperature range.)
Note: If the upper and lower limit scale settings are the same, ERR will ash twice, and the Setting mode will be displayed.

5.3.4 Low-Limit Input Value [PAR3 → L-RG]
The actually used lower limit values can be set within the analog input range. The temperature range from the
minimum value to the upper limit [H-RG] - F.S. adjustable up to 10%. Default: 0.
5.3.5 Upper-Limit Input Value [PAR3 → H-RG]
The actually used limit values can be set within the analog input range. The lower input limit [L-RG] + F.S. can be
set from 10% to the maximum value of the temperature range. Default: 10.
5.3.6 Scale Decimal Point Position [PAR3 → DOT]
The decimal point position can be set for Current Measured Value (PV) and Set Value (SV) on the upper and
lower limit scales. Available settings: 0000 / 000.0 / 00.00 / 0.000. Default: 000.0.
5.3.7 Lower Limit Scale Value [PAR3 → L-SC]
Sets the display scales for the lower limits of the analog input [L-RG]. (Based on the decimal point setting.)
Default: 0
5.3.8 Upper Limit Scale Value [PAR3 → H-SC]
Sets the display scales for the upper limits of the analog input [H-RG]. (Based on the decimal point setting.)
Default: 100.
5.3.9 Input Offset Correction [PAR3 → IN-B]
This function is used to correct the offset provided by thermocouples, RTDs, or analog input devices. The input
correction function is mainly used when the sensor cannot be xed directly to the controlled objects. Temperature
difference compensation must be performed between the sensor installation point and the actual measuring
point. Default setting: 0, unit: °C / °F / -.
Example: If the controller shows 78 °C when the actual temperature is 80 °C, set the input correction [IN-B]
to “002” to set the temperature displayed on the controller to 80 °C.
Note: If the Process Value (PV) of each input sensor after input correction is out of the input range, “HHHH” or “LLLL”
will appear on the display. Make sure that an accurate temperature variance measurement is performed before setting
the input correction. Inaccurate initial measurement may result in greater deviation.

5.3.10 Input Digital Filter [PAR3 → MAvF]
Stable control is not possible if the Process Value (PV) uctuates due to rapid input signal changes. Using the
input digital lter function stabilizes the PV for more reliable control. Default setting: 0.1 s.
Example: If the digital input lter is set to 0.4 seconds, the digital lter applies to the sampling value collected in
0.4 seconds. (400 ms).
Note: The Process Value (PV) may differ from the actual input value when using the digital input lter.
5.3.11 Upper Limit [PAR3 → H-SV] and Lower Limit of Set Value (SV) [PAR3 → L-SV]
The Set Value (SV) range can be limited within the temperature range of the temperature sensor or analog input
to prevent system control by improper SV.
Parameter Description / Range Default
H-SV SV lower limit +1 digit to upper limit value of sensor input or analog
scale
1350 (temperature) °C / °F
000.0 (analog)
L-SV Lower limit value of sensor or analog scale to SV upper-limit -1 digit –200 (temperature) °C / °F
100.0 (analog)
Note: Setting values outside the min/max input range or analog upper/lower limits is impossible. The previous settings are
retained instead of such values. The Setpoint (SV) can only be set within the lower limit of SV [L-SV] and the upper limit of
SV [H-SV]. The lower limit of SV [L-SV] must not exceed the upper limit of SV [H-SV].
5.4 OUTPUT SETTINGS
5.4.1 Selecting a Control Output [PAR3 → OUT2]
On models with a current loop output, current (CURR) or SSR drive output can be selected. Default setting: SSR.
5.4.2 SSR Function [PAR3 → O2.SR]
The SSR function only works with standard output [STND] on current models, so additional settings are not
available.
The way the load is controlled works the same way as the relay output type. (ON: 100% output level, OFF: output
level 0%)

5.4.3 Current Loop Output Range Settings PAR3 → O2MA]
If the control output is set to current output (CURR), the current output’s upper and lower limit range can be
4… 20 mA or 0… 20 mA. O2MA: Sets the current output range of OUT2.
Note: This parameter is only available on models that support [OUT2] current output.

5.5 CONTROL OUTPUT
Output modes for general temperature control include heating mode or cooling mode and heating and cooling mode.
Heating control and cooling control are opposite operations with inverted outputs. The PID t i m e constant va r i e s de-
pending on the characteristics of the section controlled during PID control. The value of the control output is MV
(Manipulated Variable). MV is a percentage value that controls the switching of the assigned device output
according to the settings.

5.5.1 Heating Control [PAR3 → O-FT → HEAT] or Cooling Control [PAR3→ O-FT → COOL]
Heating control mode: If the Process Value (PV) falls below the Set Value (SV), the output will power the heater.
Cooling Control Mode: If the Process Value (PV) rises above the Set Value (SV), the output will power the cooler.
5.5.2 Heating & Cooling Control [PAR3 → O-FT → H-C]
Heating and cooling control mode: heating and cooling with a single temperature controller if it is difcult to cont-
rol the temperature of the object by heating or cooling alone. The heating and cooling control mode uses different
PID time constants to control heating and cooling. It is possible to set the heating and cooling control in both PID
control and ON / OFF control modes.
For heating and cooling control, the relay control output OUT1 is assigned to the heating control, and the SSR
/ current control output OUT2 is assigned to the cooling control. Note that the OUT2 SSR drive output uses
standard (on / off) control.

5.5.3 Deadband/Overlap Band [PAR2 → DB]
It is possible to assign a deadband between the heating and cooling control bands based on the Set Value (SV) for
heating and cooling. A deadband is formed around the SV when a positive (+) value is set. There is no regulation in
the deadband, so the heating and cooling MV (Manipulated Variable) will be 0.0% in the deadband formed. When
the negative (-) value is set, an overlap band (simultaneous heating and cooling MVs) is formed around the SV.
Set to 0 if no deadband or overlap band is used.
When setting the integral time, this applies if the integral time for the heating control and cooling control is set.
It also acts as a P-P controller for PI-P control and P-PI control.
Ranges and default settings:
[OUT1 / OUT2]: PID / PID, PID / ON-OFF, and ON-OFF / PID control
–Set the range (temperature): – (proportional band) + (proportional band)
(lower value when using different proportional bands)
–Set the range (analog): –99.9…+99.9
–Default: 0000 (temperature H),000.0 (temperature L, analog),
(unit: temperature °C / °F, analog % F.S.)
[OUT1 / OUT2]: ON-OFF / ON-OFF control
–Set the range (temperature):
–999 (overlapping band) –0000 (not used) –+999 (deadband) (temperature H)

5.5.4 MV Upper Limit Value [PAR2 → H-MV] and MV Lower Limit Value [PAR2 → L-MV]
The upper / lower limits of the control output MV [H-MV / L-MV] can be set to the actual MV, provided that the MV
calculation of the temperature controller exceeds the limits.
When controlling heating and cooling, the cooling MV contains a „-” prex. Therefore, the upper limit displayed on
the heating side is +, and the lower limit is displayed on the cooling side.

Note: The same MV limits apply during auto-tuning. The MV limits do not apply to manual control, MV when control is
stopped, MV sensor failure, and initial manual control. The MV upper / lower limit conguration is not available in the ON /
OFF standard control mode (heating or cooling control).
5.5.5 MV Settings for Sensor Break Error [OPEN] [PAR5 → ErMV]
In the event of an open sensor error, the output value of the controller can be set to a predened MV value instead
of ON / OFF or PID control. Ignores the MV based on the ON / OFF or PID control and sends a control value based
on the specied MV. Default setting: 0.0%
5.5.6 RAMP Settings [PAR2 → RAMU/ RAMD/ rUNT]
The ramp is a function that congures the temperature per unit time to the Setpoint (SV). The function limits the
rate of change of the Set Value (SV) and thus limits sudden temperature changes (increase and decrease) in
the control system.
The ramp is typically used in applications where rapid temperature changes (increase and decrease) can adver-
sely affect the controlled system.
Control is based on the changed SV (hereafter: RAMP SV) – based on the preset rate of change (temperature
changing per unit time). The RAMP uplink rate and the RAMP downlink rate can be congured independently.
Parameter Description / Range Default
RAMU Setting for RAMP-UP change rate 0 °C / °F / Digit
RAMD Setting for RAMP-DOWN change rate
rUNT RAMP time unit (SEC / MIN / HOUR) MIN
Note: Activating the RAMP function when RAMP is not operating limits the Set Value (SV) rate of change based on the
Process Value (PV). Changing the SV or RAMP parameters during RAMP operation limits the rate of change of SV based
on SV at the time of change.
The alarm occurs during the RAMP based on the nal SV. Setting the RAMP rate to 0 turns off the RAMP functi-
on. When the RAMP function is on, RAMP SV appears in the SV display area.
RAMP depending on operating status:
Operation Ramp UP/DOWN Ramp
All operations When 0 Inactive
OPEN, HHHH, LLLL, auto-tuning, switching from Auto to Manual,
switching from Run to Stop Regardless of status Inactive
OPEN, HHHH, LLLL, after Auto-tuning has nished, PV = SV Regardless of status Inactive
Switching ON, SV change, switching from Stop to Run, switching from
Manual to Auto, Ramp rate change When not 0 Active

5.5.7 Auto/Manual control settings
The automatic mode is for the temperature to reach SV with the MV value calculated by the PID control.
The purpose of the manual mode is for the temperature to reach SV with a user-dened MV value.
Note: In manual mode, parameter settings can only be viewed and cannot be changed (except for lock parameters). If the
[DI-1] digital input terminal function is set to automatic / manual [MAN], the button and automatic/manual changeover
will not work with communication. If the unit is turned on after a power failure or shutdown, the previous mode (automatic
or manual) will be retained.
It is possible to switch to manual mode during STOP state. It is also possible to switch between automatic / manual
mode during adjustment, but automatic tuning will stop if manual control is switched on during automatic tuning.
If a sensor break alarm occurs in [SBA] normal mode, the MV [ErMV] sensor fault will occur. The MV settings for
manual and automatic control can be changed in this state.
Operational priority: Manual control > Stop > Open (sensor disconnected)
5.5.7.1 Switching Between Manual/Auto Control
Switching to manual mode for standard control (heating or cooling):
– In ‘Normal’ mode, press the button, and the device will switch to MV monitoring mode. The SV display
shows H(heating control) or C(cooling control) and shows MV, indicating the start of MV monitoring.
–If any of is pressed during MV monitoring, the MAN indicator will turn on, and the lowest
digit (100 digits) will flash to indicate that the manual control is active.

–Press the button to move the flashing digit (100 → 101 → 102 → 103 → 100).
–Select the digit and configure the desired MV value with the buttons 0 → 1 → 2 → 3 →
4 → 5 → 6 → 7 → 8 → 9 → 0 using the buttons.
–In either state, press the button to end manual control. The MAN indicator light goes out, and the
system returns to automatic control mode.
Switching to manual mode for heating and cooling control:
– In ″Normal″ mode, press the button, and the heating MV supervision mode is activated.
The SV display shows "H" and the MV indicates the start of the heating MV monitoring.
–If one of the buttons is pressed while the heating MV is being monitored, the MAN
indicator light comes on, and the lowest digit (100 digits) flashes to indicate that the manual control has
been activated.
–Press the button to move the flashing digit (100 → 101 → 102 → 103 → 100).
–Select the digit and set the desired MV value with the buttons and switch between
0 → 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9 → 0 using the buttons.
–Press the button again, and the cooling MV monitoring mode is activated. ‚C’ appears on the SV
display and MV indicates the start of cooling MV monitoring.
– The lowest digit (100 digits) will flash if any of the buttons are pressed during cooling
MV monitoring.
–Press the button to move the flashing digit (100 → 101 → 102 → 103 → 100).
–Select the digit and set the desired MV value by using the buttons, and use the
buttons to switch between 0 → 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9 → 0.
–In any condition, press the button to end the manual control mode. The MAN indicator light goes
out, and the system returns to automatic control mode.
Note: After heating and cooling control, the system returns to automatic control in the order of heating monitoring, manual
heating control, cooling monitoring, and manual cooling control. To switch between automatic and manual mode, press the
button once. The heating MV remains valid during cooling monitoring and manual cooling control. When the [DI-1]
digital input function is set to AUTO / MANUAL [MAN], the button on the front panel and the auto / manual control
functions via communication do not work.
Switching Manual / Auto control using the digital input (DI) connector:
If the digital input function [DI-1] AUTO / MANUAL control switch is set to [MAN], turn on the DI to activate manual
mode (the MAN indicator lights up) and turn off the DI to activate automatic mode. If the digital input function is
automatic, it can only be monitored. If it is manual, it is possible to change the MV and monitor it.
Note: See 5.10.6 Digital Input for detailed information about the digital input (DI) terminal settings.
5.5.7.2 Initial MV for Manual Control [PAR5 → ItMV]
The initial MV value can be set when the device is switched from automatic [AUTO] to manual control [PrMU].
Default setting: AUTO.
–AUTO: automatically adjusted MV, as initial MV for manual control.
–PrMV: manually set initial MV [PrMV].
Note: When the power is turned back on, it starts with MV that was in use when the power was turned off.
