3 Product overview
3.1 Function
The CMSX digital electropneumatic positioner enables simple and efficient position control based on
the PID control algorithm. The position specification is provided via an analogue setpoint signal.
The current position of the actuator is detected as follows:
– CMSX-P-S-… (rotary): through an integrated potentiometer
– CMSX-P-SE-… (linear): through an external path/angle sensor
The PID controller compares the measurement value with the analogue-specified setpoint value and
actuates the solenoid valves.

3.4 Safety function
If the electrical power supply fails, the positioner will react differently, depending on the product
variants and actuator system (failure of the operating voltage supply or the setpoint specification)
èTab. 2.
If the operating voltage supply is switched back on, the last operating status is immediately effective.
If the PID controller is activated, the current setpoint value is immediately valid.
