Prerequisite for checking the safety function
● Positioner is in operation.
● The actuator belonging to the positioner is not in the safety position.
Procedure
1. In order to test the safety shutdown, apply a LOW level, i.e. a voltage of maximum 4.5 V,
2. Verify that the valve returns to the safety position.
3. In order to test the response of the actuator, apply a HIGH level, i.e. a voltage >13 V, to
4. Set the setpoint to 50% using a local operation (manual operation) or bus communication.
5. Reduce the inlet pressure (PZ) to a third of the maximum supply pressure.
6. Verify that the valve returns to the safety position.
