Warning
Before testing the valve-actuator combination:
– Make sure that nobody is in the danger zone.
Before actuating the manual overrides (MO):
Uncontrolled actuation of solenoid coils can cause the actuators to perform sudden
unexpected movements, which may cause personal injury and material damage.
• Disconnect the operating voltage supply for the solenoid coils from the correspond­
ing connections on the valve terminal.
This prevents accidental actuation of the solenoid coils.
Note
A valve that has been switched by an electric signal cannot be reset by the manual over­
ride. The electric signal is dominant in this case.
• Reset the electric signal before actuating the manual override.
Proceed as follows:
1. Switch on the compressed air supply.
2. Check the functionality and method of operation of each valve-actuator combination by actuating
the relevant manual override (è Tab. 4.3).
