It is advised to give the control input for this function a proper name, such as the name of
the zone‑loop that is supervised.
In the configuration multiple zone names can be coupled to External zone fault, just to be
capable of combining multiple fault contacts for different loops on a single control input.
These zone names will show up in the fault log in case of a fault.
Preferably only a single zone should be configured for each External zone fault control
input.
Select: Operation.
