Pneumatic actuator PAMS NC/NO/DA
12 Optional trigger and query systems
12.1 End position feedback
The bracket SV04 (3.1) and the SV compact bracket (3.2) are equipped with a feedback de-
vice. By the installation of inductive proximity switches M12x1 and a switch cam, the position
"OPEN" and/or "CLOSED" can be queried, respectively.

12.2 Control and feedback head TOP LED
The control and feedback head TOP09 is an extension module for the pneumatic actuator
PAMS. The valve position detection is done by proximity switches. The integrated pilot valve
controls two single-acting actuators. In case of double-acting actuators, two pilot valves control
the actuator.
The design of control head and pneumatic actuator allows for an internal control air flow with-
out external hoses. Apart from the electric position feedback, the device status is displayed
optically at the control head itself by a mechanic position indicator.
The control and feedback head can be adapted to any M&S standard element.
A splashwater-
protected housing contains both the proximity switches for position query and the pilot valves
required for triggering.
