7.2.10 Setting the MIN, MAX and SIL fail-safe mode
The SIL mode function is only available in conjunction with electronic insert FEI55.
By selecting the fail-safe mode correctly, you ensure that the output always operates
safely with the quiescent current.
Minimum fail-safe mode (MIN)
The output switches if the switch-point is undershot (probe uncovered), a fault occurs or
the line voltage fails.
Maximum fail-safe mode (MAX)
The output switches if the switch-point is exceeded (probe covered), a fault occurs or the
line voltage fails.
Setting the MIN fail-safe mode:
The factory setting is set to MAX fail-safe mode.
