Fig.19: Signal for low voltage
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 1 Hz 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 door hardware until the necessary voltage has been restored.
Rapid beeping (2 Hz):
The controller beeps at a frequency of 2 Hz if
y y the connected emergency power backup is charging (no error, can take up to 30 s)
y y the wiring between the controller and emergency power backup is interrupted
