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.
Function of the LEDs in the ID key-operated switch
In the enclosure of the ID key-operated switch are four illuminated surfaces that can assume
the following states:
● Showing a green light: Indication of the current key position and the switched outputs.
● Flashing green: Indication of the temporary key position.
● Showing a yellow light: Indication of the associated authorization level (key position that
can be reached by turning the rotary knob).
● Flashing yellow (all 4 illuminated surfaces): Indication for the individually encodable
ID key used that has not yet been configured.
● Showing a red light: Indicates that the relevant key position is higher than permissible for
the relevant authorization level. (This key position cannot be reached by turning the rotary
knob.) The indicator also shows a red light when there is no ID key plugged in.
● Flashing red (all 4 illuminated surfaces): When using a colored ID key with permanently
encoded authorization level (ID group 1 to 4), this indicates when the parameter
"Individual keys only" is enabled.
● Not illuminated: The electronic module is switched off.
