7.3 Shutoff module: Blocking the working pressure
The shutoff module and the air circuit should be tested monthly to en-
sure they function correctly.
7.3.1 Manually operated shutoff module
To block the operating line:
1. Use a screwdriver to turn the lock (18) 45° in an anticlockwise direction until it
releases. Then turn another 45°.
2. If necessary, protect the lock against unintentional actuation with a cable lock
for shut-off valves (material number: 7472D02758) or a lock. The hole diame-
ter is 5 mm.
To unlock the shutoff module:
1. Remove the cable lock for shut-off valves or the lock.
2. Turn the lock 45° in a clockwise direction, then push the lock in up to the end
stop and turn it another 45° in a clockwise direction up to the stop.

Apply at least the minimum pressure P2, which corresponds with the pressure
u
on connections 2 or 4, to the pilot control connection to actuate the shutoff
module.

Pneumatically and electrically operated shutoff modules feature posi-
tion detection. A sensor with M8x1 connection can be used to query
the position.

The sensor signal is supplied when no pilot air
is applied at the shutoff point, i.e. no air flows
through the operating line.
