4.6 Adjusting the ceiling cover plate
When the lift is in its upper position the cover plate should be level with the surface of the false ceiling. One method is to
fasten the screws of the extension elements on the cover plate only slightly, to adjust the upper stop position, to move the
lift upward into this position and to press the ceiling cover plate manually against the surface of the false ceiling. Afterwards
lower the lift again and tighten the screws. Also the screw
b
on the projector holder

must be secured with a spanner.
4.7 Mains connection of the control unit
!
Safety instructions:
• The switches and controls must not enable simultaneous up and down commands. This would damage the unit.
Only use mechanical or electrical switches!
• There must be an interval of more than 0.5 seconds between an up and down command. Otherwise high voltage could
damage the motor.
• Condensor motors are suitable only for short time operaqtion (approx. 4 minutes). If the motor is overheated during a
test drive or when in operation, it is switched off automatically.In such a case let the motor cool down approx. 15 minutes.
• Check whether the two carrying ropes are of the same length and are wound up tightly and orderly on the shaft of the motor.
• Make sure that the projector is brought in upward position only after it has been switched off and has cooled down.
• If the lift is operated by a media control, the programming of the media control must be done likewise and the safety
instructions must be observed.
The lift can be controlled via:
After adjusting the stop positions you must disconnect the external programming unit and connect the wiring of the motor
according to the following circuit diagram.
!
Attention:
Make sure that the wiring of the motor control is not mixed up (brown = up, black = down) when inserting the cables
for the switch/button (up/down) to the lift. Use only certified protected cables.
!
The parallel wiring of several condenser motors is not allowed (ceiling lift, electrical screen...).
In such a case use a splitter with separate inputs for each motor.
4.8 Safety power cut
The ceiling lift is equipped with a safety power cut. The condenser motor stops automatically, if the movement of the lift is
obstructed and the carrying rope is no longer under tension.
