Settings on the electronic module for ID key-operated switches
The electronic modules for ID key-operated switches have 5 digital outputs. Setting of
outputs 0 to 3 depends on the current key position and the module settings. If a valid ID key
has been recognized, output 4 is active; otherwise output 4 is inactive.

Short-circuit protection
If a short-circuit occurs at one or more outputs, the occurrence of a fault event is sent and
the fault flag is set. All outputs are deactivated for one second. Then the relevant outputs are
re-activated to monitor whether the short-circuit is still active. This temporary state exists for
approximately 0.1 seconds. If no short-circuit is determined during this period, the fault event
is revoked, and the fault flag is deleted. However, if a short-circuit is detected during this
time, all outputs are deactivated again, and the short-circuit device fault remains.
