6.2.2 Testing fail-safe digital inputs
Testing sensors and fail-safe digital inputs
The inverter tests its fail-safe digital inputs and the connected sensors with a signal change at
the inputs. We recommend that you test the fail-safe digital inputs together with the forced
checking procedure (test stop).
Procedure
To test the fail-safe digital inputs, proceed as follows:
1. Actuate the relevant sensor.
2. Check the following:
– The expected safety function is active.
– The inverter signals a fault.
You have tested the fail-safe digital inputs.
