Pid Setup Checklist And Tuning - Zener MSC-3 Instruction Manual

PID features include:
• Three term tuning (PB%, Ti, and Td).
• Output saturation with integrator anti-windup.
• Reference and feedback signal source selections.
• Open loop to closed loop initialisation.
• Process variable spanning and offset available through the selected analogue input.
• Process variable limit alarms available through the selected analogue input.
• Process variable and set point variable display.
• Process variable, motor current, motor power and motor speed display.
Key configuration parameters are:
• H01 PB (%)
• H02 Ti (sec/r)
• H03 Td (sec)
• H04 +Opt clamp
• H05 –Opt clamp
• H06 SV choice
• H07 PV choice
• H08 PID Units (for PID display)
• H09 PID Scale (for PID display)
• > PID Output (as a speed reference in REMOTE, LOCAL, ESO, etc)
Additional configuration parameters:
• Refer to the selected analogue input for spanning and offset configuration.
• Refer to the selected analogue input for limit alarm (under and over) configuration.

PID Setup Checklist and Tuning

1. Control Wiring (Assumes factory defaults are loaded)
WARNING!
All wiring must be done while the MSC3 is disconnected from the power supply. Refer
to the Control Wiring Diagram for detail
1.1. Select an analogue input for the process variable (PV) measurement. Choices include: AI(10,11),
AI(32,34) or AI(52,54)
4
1.2. Wire in the transducer that measures the PV to the selected analogue input.
1.3. If required, wire in the set point variable (SV) reference signal to a separate analogue input. No
wiring required if an internal preset is to hold the desired SV reference.
1.4. If required, wire in any metering device to an analogue output. Choices include: AO(36,38)
AO(56,58) .
5
1.5. Ensure the signal levels are compatible with the input/output specifications of each feature.
Refer to the PID Control Wiring diagram for details.
2. Preparing for PID Control
2.1. After initial power on, alter any MSC3 settings and/or selections.
4. If optional Extended Features card is fitted in the left hand option slot.
5. If optional Extended Features card is fitted in the right hand option slot
