The following instructions are for the adjustment of the limit switches that alter
the upper and lower stop positions on Interfit Projector Lifts with 300mm of
travel or longer
Where are The Limit Switches?
At the same end to the power cable (Right Hand Side).
One switch is accessible either when the lift is down or
when the side cover is removed
Which Switch is for Up and Down?
Down switch – The one closest to the rear of the lifter
Up switch – The one closest to the front of the lifter
What Tools do I Need?
Either the limit setting tool (supplied), a narrow tip screw driver (less than 4mm) or a 4mm Allen Key
Which Way do I Turn the Switch?
Clockwise always decreases the amount of rotation (travel) of the motor.
Anti‐clockwise always increases the amount of rotation (travel) of the motor.
So pick the switch responsible for the limit position, up or down. Clockwise turning of the switch will always
let the motor travel less in that direction. Anti‐clockwise turning of the switch will increase the amount of
travel in that direction.
Can I adjust the switch while the lifter is sitting on the limit ‐ i.e. fully up or down?
Anti Clockwise adjustment? – YES. But it is better to back the lifter away from the limit and then adjust
Clockwise adjustment? ‐ NO you will damage the micro switch if you turn it anti‐clockwise while the lifter is
sitting on the limit. Never attempt this. You must back the lifter away from the limit before adjustment. After
adjustment you will need to run the lifter up and down to pick up the new limit
Will I void the product warranty if I damage the lifter whilst making these adjustments?
Yes it is possible.
