6 Commissioning and Operation

Risk of injury due to uncontrolled actuator movements when the pneumat-
ics are switched on!
There is a danger of personal injury if the system is in an undefined state.
Put the system in a defined state before switching it on.
u
System is operating under pressure!
Incorrect installation could damage the product and cause serious injury.
Before commissioning, check that all connections, ports and maintenance
u
equipment have been correctly installed.

6.1 Commissioning the pressure switch

Proceed as follows to commission the pressure switch:
1. Check whether the pressure switch is mounted correctly (see sec-
tions "g 5. Assembly" and "g 2. Notes on Safety") and make sure that all pres-
sure switch connections are properly connected.
2. Secure the components to be switched to prevent unintentional responses,
and apply voltage.
3. Apply the compressed air to the system.
4. Check that the switch outputs are functioning properly.

6.2 Setting the switching point

See g Fig. 14
Increase the switching point pressure by turning the adjustment screw (1) to the
right (+). Max. torque for adjustment screw 1 Nm.
1. The adjustment screw is self-holding and also remains in the set position with-
out any additional securing, even under unfavorable circumstances.
Reduce the switching point pressure by turning the adjustment screw (1) to
the left (–).
Information on factory settings: see online catalog and name plate.
2. Use an external pressure gauge to check the setting value (switching point).
INFO: The switching point is continuously adjustable, even during operation.
The optimum selection range is when the switching point is in the middle of
the switching pressure range. Optionally, a pressure gauge can be used as an
aid.
