SCREEN ADJUSTMENT
RECALIBRATION
The screen controller (standard control, not SCB100 or SCB200) is factory calibrated to control the screen and door
sequence timing. If the line voltage varies 10% or more from the factory setting, the door will not close properly and the
unit will need to be recalibrated. The steps are:
1. The screen surface must be all the way up
2. Press and hold the stop button for 10 seconds
The screen will then run through a whole cycle and be recalibrated upon completion. Press "up" button to close door after
recalibration.
If the screen limit switch setting is changed in the up direction, the unit must be recalibrated. Surface travel is stopped
automatically in the fully opened and closed positions by limit switches that are factory set 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. P lace operating switch in "down" position.
2. W hen the screen stops, turn the white "down" limit knob (Fig. 2) one-quarter turn counterclockwise. Test by raising
picture surface approximately two feet, then lower again. Repeat until desired picture surface position is attained.
