Thank you for choosing a NIVELCO product!
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
5.1 PARTS AND DISPLAY
The seven-segment displays show the measured (Process
Value, PV) and set values (SV) in regular operation, while
in other modes, they show the corresponding text signals
and values according to the current status of programming
and setting. Use the 4 buttons to operate the menu system
and perform programming. 6

1. Measured Value (PV):
RUN mode: it shows the currently measured value (PV).
Setting mode: it shows the name of the parameter.
2. Set value (SV):
RUN mode: it shows the set value (SV).
Setting mode: it shows the the parameter value.
3. Unit (°C / °F / %) indicator: It displays the unit set in parameter group 3. The unit applies to the displayed
values of the PV and SV.
4. Manual control indicator (MAN): it switches on during manual control.
5. Multi SV indicator (SV1, SV2, SV3) LEDs: Indicates the different target value setting currently in use
(SV1-3). The base destination eld (SV0) is valid if none is active. Not available for all models.
6. Auto-tuning indicator (AT): ashes every 1 second when auto-tuning is executed.
7. Alarm output (AL1) indicator: it turns on when the alarm output is on.
8. Control output (OUT1, OUT2) indicator: it turns on when the corresponding control output is active. During
manual control, it switches off if the measured value is 0.0% when using a current output; otherwise, it is
switched on continuously. During automatic control, it switches on when the measured value exceeds 3.0%
and switches off when it falls below 2.0%.

the set value
Functions:
9.1 Press and hold the button for longer than 2 seconds in RUN mode to enter Setting mode.
9.2 Press and hold the button for 1.5 seconds to enter another parameter group in Setting mode.
9.3 Press and hold the button for longer than 3 seconds in to return to RUN mode from Setting mode.
9.4 Press and hold the button at the last parameter name of any parameter group, and the device
returns to the current main parameter group, where other parameter groups can be accessed.
9.5 If no button is pressed within 30 seconds in setting mode, the device will automatically return to RUN
mode, and the previously saved setting value will be retained.
10. buttons: they are used when entering the set value, changing mode, navigating between
parameters/values, and changing values up/down.
11. Digital input key: When pressing the buttons together for 3 seconds, it operates the
RUN/STOP, alarm clear, and auto tuning functions.

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.
5.3.1 Input Types [PAR3 → IN-T]
The device supports multiple input types, allowing the user to choose from various thermocouples, resistors,
and analog voltages/currents.

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.
