Page 4: Introduction
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... -

The characters of the 7-segment display 5.2 STARTUP When energized, the display will flash for one second, at which point all display sections will illuminate. Then the hardware ID code and the input sensor type will flash 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. -

Page 12: Input Digital Filter [Par3 → Mavf]
5.3.10 Input Digital Filter [PAR3 → MAvF] Stable control is not possible if the Process Value (PV) fluctuates due to rapid input signal changes. Using the input digital filter function stabilizes the PV for more reliable control. Default setting: 0.1 s. Example: If the digital input filter is set to 0.4 seconds, the digital filter applies to the sampling value collected in 0.4 seconds. -
Page 13: Control 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 time constant varies de- pending on the characteristics of the section controlled during PID control. The value of the control output is MV (Manipulated Variable). -
Page 14: Deadband/Overlap Band [Par2 → Db]
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. - Page 15 When db is in 10 digits Control output MV Heating hysteresis/offset Cooling proportional band 100.0% Cooling control Heating control Process value SV+5 Cooling MV Deadband ON/OFF heating control and PID cooling control When db is in 10 digits Control output MV Heating hysteresis/offset Cooling hysteresis/offset Cooling control...

Page 22: Pid Control [Par3 → C-Md → Pid]
Temperature ON_Offset OFF_Hysteresis Time (t) Control output Cooling control Hysteresis [PAR2 → hHYS/hOFT/cHYS/cOFT] Hysteresis is the setting of the control output on and off point in ON / OFF mode. ON_Hysteresis sets the output to an ON point, and OFF_Offset sets an off point. The values are set in °C / °F. If the hysteresis is set too low, the disturbing characteristics that affect the device (noise, etc.) will turn the output control (compared to the control characteristics) uncertainly on and off, which should be avoided. -
Page 23: Setting The Proportional Band For Heating [Par2 → H-P] And Cooling [Par2 → C-P]
5.6.3.1 Setting the Proportional Band for Heating [PAR2 → H-P] and Cooling [PAR2 → C-P] If the Process Value (PV) is within the proportional band (P), the ON / OFF ratio must be adjusted during the proportional period (T). The defined proportional control (time proportional control) section is called the proportional band. -
Page 24: Auto-Tuning
5.6.4 Auto-Tuning Automatic tuning measures the controlled section’s temperature characteristics and thermal response rate and then determines the required PID time constants. (If the [C-MD] control type is PID, it is displayed.) This operation will stop automatically if an [OPEN] error occurs during auto-tuning. To stop auto-tuning, change the setting to OFF. -
