Determining an alarm condition

At the control module, it is possible to determine the cause of a fault provided it
is still applicable.
For this purpose, proceed as follows. First the alarm must be acknowledged by
momentary contact of the key-operated switch at the terminal in the counter-
clockwise direction. The green LED now starts to flash; the yellow LED goes
out. Then turn the key-operated switch first counterclockwise then clockwise,
hold and watch the display in the control module. The displays at the control
module allow the cause of the alarm to be ascertained using the following table.
Once this has been remedied, the door can be locked again at the key-operated
switch, i.e. the system can be restored to its basic status.
Table for determination of an alarm condition:
Triggering criterion
Sabotage at the control, terminal, po-
wer supply or the operating unit
Door sabotage
Emergency open
(door was unlocked)
Emergency open
(door was locked)
No locked status feedback signal
External emergency unlocking
(e. g. fire alarm system)
(*)
In this case, the green LED does not flash after acknowledging the alarm. However, if the door
contact still remains open, a locking command is not accepted. The same applies if a door-open
alarm has been triggered because the door remained open too long after a temporary release.
