5.2 Function
The CMSX digital electropneumatic positioner enables simple and efficient position control based on
the PID control algorithm. Positions are specified via an analogue setpoint signal. The current position
of the actuator is detected as follows:
– CMSX-P-S-... : through an integrated potentiometer
– CMSX-P-SE-... : through an external path/angle sensor
The PID controller compares the measurement value with the specified analogue setpoint value
and controls the solenoid valves.

5.4 Safety functions
If the electrical power supply fails, the positioner will react differently depending on the product vari-
ants and actuator system (failure of the operating voltage supply or the setpoint specification)
è Tab. 3 Threshold values for safety function and
è Tab. 4 Overview of safety position (pneumatic initial position).
If the operating voltage supply is switched back on, the last operating status is immediately effective.
