Pneumatic control variations
The Control Module contains all the necessary pneumatic
components to control the actuator and control the incoming
and outgoing airflow. Pneumatically the modules are available
for three applications:
1. Spring return or
2. Double acting or
3. Double Acting - "Fail-in-Last-Position".
To achieve these functions, each Control Module can be
fitted with one or two pilot valves depending on the required
functionality:
1. One pilot valve is default and suitable for normal operation
of double acting or spring return actuators
2. Two pilot valves are required to achieve a "Fail-in-Last-
Position" functionality on double acting actuators.

Wiring diagram shown, is applicable for actuators with assembly code “CW”. For
actuators with assembly code “CC” (reverse acting) the “Open” and “Closed”
pilot valve connections are also reversed.
