ADJUSTMENT OF PITCHING AND ROLLING OF THE PROJECTOR
Projectors have not a regular distribution of the weight on their surface but tent to have unbalancing
caused by the lamp, by the optical system and so on.
Unbalancing could lead to either a right and left rolling or a pitching of the lower lift frame - projector.
The PPL 2500 have been developed in order to solve these problems and allow to adjust the lift in order
to get a perfect balance of the entire lifting system.
In order to adjust PITCHING, please move the motor along the profile where the motor itself is fixed, by
loosen the screws as shown on Fig. 5A and 5B and move the motor left or right until the lower frame will
be perfectly balanced (Fig. 5C).
Please proceed, with this step, after having laid the projector mounted on the frame on a support
surface, in order to lighten the motor from the weight.
Now loose the screws on Fig. 5D and by using a rubber hammer, move the profile of Fig. 5E, left or right
in order that the steel cables are perpendicular both on the upper part and on the lower part of the lift
(see Fig. 5C. At the end of the adjustment tighten the screws firmly (Fig. 5D).
