10.5.2
Acoustic signaling
There is an acoustic signaling by buzzer signal. This serves three purposes described in the following sections.
10.5.2.1
In inspection mode
If during inspection trip the position approaches inspection limit switches, the Safe Box emits continuous short
acoustic signals. The closer the position gets to the inspection limit switch, the faster are the signals. If the in-
spection limit switch has been overrun, there is a continuous signal. The signal is only emitted as long as a trip
in the dangerous direction is requested by pressing a direction button.
10.5.2.2
Assistance to the teach button
If the teach-button is kept pressed, there will be a short acoustic signal after 2 s and a long signal after 5 s. If the
operator wishes to request a transition into / exit from teach mode, he presses down the button until the long
signal is emitted and then releases the button. If the operator wishes to request a transition into/ exit from ad-
justment mode, he presses down the button only until the short signal is emitted and then releases the button.
10.5.2.3
Signaling teach and adjustment mode
In teach and adjustment mode a short beep is emitted every two seconds to draw attention to the technician.
10.6
Connectors and Interfaces
The following chapters will give you detailed information on the connections and interfaces.
10.6.1
Power supply
The LIMAX Safe is supplied by 24 V. There is also a supply for a 12 V emergency supply (by battery). Connecting
the battery is optional. It ensures the operation of the door zone contact DZ-SUP / DZ in case of power failure.

CANopen Interface
The CAN-bus is the physical layer of the communication interface to the lift control.
The shield has to be connected on side of lift control to protection earth.
