1 Safety
1.1 Intended use
The positioner is intended for controlling the position of the following actuators in
process automation systems:
– pneumatic quarter turn actuators (single- or double-acting)
– pneumatic drives (double-acting) with connected external path/angle sensor
Quarter turn actuators with a mechanical interface in accordance with VDI/VDE
recommendation 3845 are suitable for operation of the positioner CMSX-P-S...
(rotary).
• Mounting and commissioning is to be carried out only by qualified personnel,
in accordance with the documentation.
• The product may only be used in its original status without unauthorized
modifications.
• Only use the product if it is in perfect technical condition.

2 Product overview
2.1 Function
The CMSX digital electropneumatic positioner enables simple and efficient posi­
tion 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
Festo AG & Co. KG setpoint value and actuates the solenoid valves.
