ratchet. Slat should move freely (Fig. 1).

review your electrical installation checklist and wiring diagram

voltage control.
NOTE: Must be installed in accordance with the requirements of
the Local Building Codes, the Canadian Electrical Code (CEC), CAN/
CSA C22.1 and the National Electric Code (NEC), NFPA 70.

and down several times. Be prepared to stop screen. Standard
Duty Cycle: 1 MIN. ON / 3 MIN. OFF.
NOTE: When rolled down, the picture surface should wrap fully
around the roller. No part of the roller should be exposed. Picture
and mask surfaces will automatically stop in the down position.
The mask will start down off the front of the roller, travel completely
down past the bottom of the viewing surface, then “step back”
against the viewing surface to eliminate shadowing by rolling up
the back side of the roller. Do not adjust the limits to change this
feature.

mask surfaces are fully up the limit switches (in the motors) are
tripped and the motors shut off.
11. Check for satisfactory condition by operating screen a few times.
