All operating switches should be “off” before power connection.
5.

Caution: Before operating the first time, make sure that nobody is standing under the projector lift. Adjust bottom limit switch
so that nobody gets injured during operation. See next chapter on how to adjust the limit switches.
3.2 Limit switch adjustment:
The automatic stop positions (the positions where the lift stops when extending and where it stops when
retracting) can be adjusted as required. These are preset and for most situations,
the switches should not need adjustment.
To adjust the switches, use the equipped
allen key
. The adjustment sockets are
located at the left side under the lift top plate (viewing from the front);
The yellow hole is for adjusting upper limit. Clockwise movement will reduce upper
limit and anticlockwise movement is for increasing upper limit.
The white hole is for adjusting down limit. Clockwise movement will reduce down
limit and anticlockwise movement is for increasing down limit.
Caution: Rated motor continuous operation time is 4 minutes. Excessive operation may cause
the motor to overheating and will stop running due to a protective function. When this
occurs, please stop for 15 minutes to wait the motor to cool down and then star operation
again.
