BOARDROOM ELECTROL

220 / 240V

WIRING DIAGRAM

NOTE: A SINGLE SWITCH CANNOT BE USED TO OPERATE MORE THAN

ONE SCREEN. CONTACT THE FACTORY FOR FURTHER INFORMATION.

SCREEN ADJUSTMENT FOR 220/240V SCREENS

Surface travel is stopped automatically in the fully opened and closed positions by limit switches that are properly ad-

justed at Da-Lite. Should it be necessary to adjust for more or less drop of picture, proceed in the following manner:

NOTE: Use a screw driver or 5/32" allen wrench to make adjustments.

MORE SCREEN DROP

1. Place operating switch in "down" position.

2. When the screen stops, turn the white "down" limit knob (Fig.5)

one-quarter turn counterclockwise. Test by raising picture surface

approximately two feet, then lower again. Repeat until desired

picture surface position is attained.

LESS SCREEN DROP

1. Raise picture surface approximately two feet above desired level.

2. Place operating switch in "off" position.

3. Turn the white "down" limit knob (Fig.5) one-quarter turn clockwise. Test

by raising picture surface approximately two feet, then lower again. Repeat until desired picture surface position is

attained.

If the surface door does not close flush with the access door, it may become necessary to adjust the door limit

switch (Fig.5). Turn the adjusting knob (counterclockwise if door is not closing enough; clockwise if door is closing

too much) in increments of one-quarter turn until the surface door is flush with the access door.

CAUTION! Do not over adjust. This will place unnecessary strain on the fabric slat pocket and could cause damage to the

screen surface.
