Commissioning
8.1
Safety
The product is equipped with a pneumatically-piloted shut-off valve. If there is pressure at pneumatic
connection 1, the shut-off valve is open in the normal position.
With preset parameters and applied input pressure P1 the shut-off valve automatically switches to the
pressurise state in the following cases:
–
Switch-off of the operating voltage or the load voltage
–
Interruption of the network communication with correspondingly set system parameters
–
Stopping of the higher-order controller (see manufacturer's specifications), e.g. in the case of
transmission of control programs, parameters, configuration data
If the shut-off valve was previously closed and the system was exhausted, the system is suddenly
pressurised. Take this response into account in the design of the system.
