Description

The LightWatcher from W+W reduces the energy costs in the area of cabin lightings, without interfering with the electronics of the lift.

Simple installation on the car roof by integrating the LightWatcher into the circuit of the cabin lighting, no supplementary wiring is necessary.
Any movements of the car can be detected by three integrated acceleration sensors. The sensors are sensitive enough to recognize also door movements.
As soon as a movement in the car is perceived, the cabin light is switched on. The switching threshold for sensing movements can be set directly on the LightWatcher-gadget. Provided that no further car or door movements are sensed, a certain time will elapse before the cabin light is switched off again.

To install the LightWatcher, the lighting branch-circuit is simply cut and the LightWatcher is put in.
The LightWatcher can, apart from the cabin light, switch off an additional consumer. Moreover, for the powersaving mode a third contact has been provided that can switch on a consumer so as to activate the emergency light for example.
For special applications that require the cabin light to be activated not only by the movement-sensors but also by other sensors or functions, four potentional-free inputs have been provided, that can be used reversely as well.
All relay contacts are closed, if the LightWatcher is not supplied with operating voltage.
The LightWatcher in case can simply be laid on the cabin roof.

The LightWatcher from W+W is suitable for CabinLED 3-pole, HomogenLED, complete ceilings with CabinLED5 and SQUARE-LED.
