Variante 1:
Auftrennung des Sicherheitskreises
disruption of safety circuit
Figure 4: Modification of the safety circuit (variant 1)
Explanationofthewiringdiagram:
›The safety circuit is interrupted at the end of the series connection of the door contacts. The door contacts are
connected to input C-6.
›With the aid of the door relay, the safety device ensures that the safety circuit is closed if all doors are closed.
For this purpose, the start of the door series connection must be connected to input C-1, and the end (after
interruption) must be connected to C-3.
›The safety circuit input D-5 should be connected to the end of the safety circuit. It is responsible, among other
things for the detection of the loss of traction, i.e., if the a safety circuit is open but the car is still moving or is not
braked, it is „force-braked“.
›The relay of safety circuit can be looped in at any point in the safety circuit. It opens in case of an error (e.g.,
A3 detection) and is closed again by resetting the error. The safety circuit relay is not bypassed by override.
To release persons by means of auxiliary mode control, it must be placed at a point in the safety circuit that is
bypassed by auxiliary mode. The safety circuit relay is opened every 24 hours for a short time. This is neces-
sary to guarantee the proper operation of the relay.
Attention! During simultaneous use of override and the auxiliary control make sure that all shaft and car doors
are closed.
