LIGHTWatcher
LIGHTWatcher 4.4
Since the EU directive 2002/91/EG was published, energy efficiency is in the focus of building engineering and management experts. With the publication of VDI 4707
in March 2009 this issue is also of topical interest for lift systems. Today systems and plants which are part of the building inventory are considered to consume large amounts
of energy.
In lift systems this consumption can mostly be put down to the lift car lighting system.
The LIGHTwatcher allows you to simply turn off the lift car lights when these are not needed without a major installation expenditure, new
cables or control system modifications being necessary.
What shares in the energy consumption of a lift at a
standstill?
Operation of the LightWatcher:
The LIGHTwatcher is installed directly on top of the lift car roof allowing lift car
movements to be detected by the three integrated acceleration sensors. The
sensors are so sensitive that they even identify movement of the lift car
doors.
The lift car lights are turned on as soon as a movement is detected inside the
lift car. The switching threshold for the detection of movements is directly set on
the LIGHTwatcher.
Upon expiry of a time span adjusted by you, the lights are turned off again when
no further movements of the lift car and doors are detected.
The installation of the unit requires the electric lighting circuit to be opened and
the LIGHTwatcher to be inserted. Since the unit is powered by the electrical
lighting circuit, no extra cables are needed.
Apart from the car lights the LIGHTwatcher can turn off another consumer.
An additional third contact is provided which in the energy saving mode connects
another consumer e.g. activating the emergency light instead of the regular lift
car lights.
Three potential-free inputs are available for special applications requiring other
sensors than the acceleration sensors to activate the lights.
• Event-controlled cutout of lights when the lift is stationary
• Minimisation of the stationary demand conform to VDI 4707
• Independent detection of lift car and door movements
• There is no need to tamper with the lift system electronics
• Simple installation directly in the electrical lighting circuit
• Cutout behaviour can be influenced via control inputs
• Suitable for being attached to tophat rails and walls
