5 Projector Lift Positioning Function There are 2 methods to position the projector lift - set by the upper and lower limitations on the remote. Specifications Product Specifications 1) Upper/Lower Limitation Adjustment for Sling Wires The upper and lower limitations are preset at the factory. The upper limitation is slightly higher than the ceiling and the lower limitation is shown in value D on the specifications table. Please note the upper and lower limitations for the sling wire installation must be done by an qualified technicianto prevent any injury or damage. Model GPCK-MB Size(unit:mm) 360~ Limitation of Ceiling Height Larger than 470mm GPCK-MB ~ Larger than 470mm Figure 20 Figure 21 The following steps must be done by an qualified technician. a) For upper limitation adjustment, take off the knob and use the provided allen key to adjust. A clockwise adjustment will retract the projector lift (the distance of the installation position of the casing will decrease) and a counterclockwise adjustment will extend the projector lift position (the distance of the installation position of the casing will increase). b) For lower limitation adjustment, take off the knob and use the provided allen key to adjust. A clockwise adjustment will retract the projector lift (the distance of the installation position of the casing will increase) and a counterclockwise adjustment will retract the projector lift position (the distance of the installation position of the casing will decrease).

6 Installation This lift needs to be installed recessed into the ceiling. The instruction below shows us the grille-ceiling as an example so please install the screen based on your installation requirements. The lift needs to recessed at the proper level to ensure correction operation. Take out all parts and accessories and follow the guideline to ensure you have all the needed parts. * For your safety and to ensure proper installation, please read this manual carefully and choose a installation needed for your environment. Figure A shows an extended installation with screws while figure B is a direct installation. Connect the power for projector lift A, and send out directive oxff ox10 ox11 ox12 oxaa. At the same time, the address of projector lift A is ox10 ox11 ox12. Entering the operating address of projector lift A can control this projector lift. Directive for retracting: Directive for stopping: Directive for extending: Completed the studying in projector lift A, and then disconnect the power for projector lift A. Please operate the projector lift B in the same way and change the address to oxaa oxaa oxaa. Entering the operating address of projector B can control this projector lift. Concrete Concrete Directive for retracting: Directive for stopping: H Hanger Screw H-400 H Directive for extending: This studying is one address bit for a long time untril next address bit change to update. After studying address bit, the common directive is still effectivr, so the address bit can not be oxee oxee oxee.

The bracket is a part of the projector lift combined with the hanger, screw (M10), and nut (M10) to be following mechanism. Cut the length of the screw (M10) for H-C+60mm, where H is the distance of the concrete ceiling and the ceiling surface (measured in the last step). C is the height of the frame as shown in the specifications table. H-C+ 60 Cotter Pin H-400mm probably 60mm Hanger M10 Nut M10 Threaded Rod M10 Locknut Figure 3 114m m 3. Ensure the distance M and N is according to figure 4 and the model of the table below. Install the brackets to the ceiling via screws as shown in figure 5.

The learning directive is oxff oxxx oxxx oxaa. The lift can be used after the learning process is completed, but it cannot be used properly after the address bit is changed. Tis is because one port can used to control many projector lifts. Example: If there is a projector lift A and B with RS-485 ports, in order to control these two lifts simultaneously the directive oxff oxee oxee oxee oxdd will be sent out from the port. In order to control these two lifts in different movements, for example lift A goes down while left B goes up, a common directive cannot be used and must be separated by an address bit at this time H M Figure 4 N Figure
