Description of functions of additional components
Wheel-block sensor (X5)
If the wheel block is placed against a tyre of the vehicle, the dock leveller can be operated.
The external traffic lights change from green to red. Activation with menu 3.1
Vehicle detector, external (X6)
If the vehicle is detected by the detector, the external traffic lights change from green to red.
Activation with menu 3.2
Mechanism for release/locking of dock leveller/door (X7)
The “door - dock leveller” or “dock leveller - door” sequence is controlled via the lock contact.
It is possible to incorporate a vehicle detector for the release function. The door release
contact is switched with the dock leveller at its standby position. Activation with menu 5.1
Position sensor for dock leveller (X8)
The detection of the dock leveller at its standby position is achieved via an external additional
contact. Activation with menu 3.3
Traffic lights / Lighting (X9)
The dock-leveller control system has outputs for a headlamp as well as internal and/or
external red/green traffic lights.
External red/green traffic lights
The green lamp indicates to the driver the operational readiness status of the dock leveller for
docking. Once the lorry has docked, the traffic lights change to red. Here, a wheel-block
sensor or vehicle detector needs to be used. If no sensor is connected, the traffic light
changes to red as soon as the home position is left. The changeover from red to green is
controlled via a time period setting. The time period starts as soon as the dock leveller has
again reached its home position. If a wheel-block sensor is active and engaged, there will be
alternate flashing of the red and green traffic lights after the changeover period has elapsed.
