Acoustic warning signals

The controller emits a range of different beeps as acoustic warning signals.
1. Continuous tone (1 s):
B-54900-01-4-9
I1:
Fig.16: Signal service plug
A continuous tone signals a control signal on one of the two control inputs I1/I2 when the
service plug is inserted.
2. Slow beeping (1 Hz):
B-54900-01-4-9
≤ 21 V DC

If the voltage at connecting terminals G2 and V2 drops below 21 V DC, the controller emits a
beeping sound at a repetition frequency of 1Hz and the lock moves to the initial position.
The control inputs are disabled. This prevents electromechanical actuation and the lock can only be
actuated mechanically via the hardware until the necessary voltage has been restored.
