2.1 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.
 Observe the product labelling.
 Only use compressed air in accordance with the specifications èTechnical data.
 The cable connector supplied only for cable throughfeed. To achieve the degree of protection IP65,
seal each cable entry tight (cable fitting, blanking plug).
 Observe the handling specifications for electrostatically sensitive devices.
2.2 Return to Festo
Hazardous substances can endanger the health and safety of personnel and cause damage to the
environment. To prevent hazards, the product should only be returned upon explicit request by Festo.
 Consult your regional Festo contact.
 Complete the declaration of contamination and attach it to the outside of the packaging.
 Comply with all legal requirements for handling hazardous substances and transporting dangerous
goods.

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.
