Safety instructions for adjusting the stop positions
1. The switches and controls must not enable simultaneous up
and down commands. This would damage the unit. Only use
mechanical or electrical switches.
2. There must be more than 0.5 seconds between an up and
down command.
3. Avoid overheating during test drives and in normal operation,
i.e. the motor should not work uninterruptedly for more than 4
minutes. Overheating may trigger off the inbuilt thermal switch.
In such a case, please wait at least 10 minutes until the unit is
ready for use again.
4. Check whether the two towing ropes have the same length
and are wound up tightly and evenly on the shaft of the motor.
5. Make sure that the projector is brought in upward position
only after it has been switched off and cooled down.
That means: After the lamp is off and the projector signals
STANDBY, you must wait at least 5 minutes until the lift can
be raised to stop position 1.
If the unit is automatically operated by a media control system,
this has to be programmed correspondingly.
Mounting the projector
Prerequisites of the projector:
Three or four drill-holes (M3, M4, M5 or M6) on the bottom,
distance between the drill-holes between 75 and 370 mm.

Adjustment of the projector
1. The projector hanging from the cross bar can be easily rotated
resp. tilted by about
±
20
°
.
If the position of the projector in relation to the screen is correct,
the screw of the projector holder (8) can fastened with a
spanner.
2. The projector holder is located in the centre of the cross bar
(7) and can be shifted to the left and right resp. to the rear if
required (see illustration).
To this effect loosen the screw of the projector holder. Make
sure that the screws of the carrying arms remain accessible
when shifting the holder.
3. After loosening the four screws the cross bar (7) can be taken
off to the left or to the right or can be rotated if required,
provided the height of the false ceiling allows it resp. the
projector would otherwise not fit onto the cross bar
(illustration 4)
.
