Screen Adjustment
Motor Limit Adjustments
Surface travel is stopped automatically in the fully opened and closed positions by limit switches that are properly adjusted at Da-Lite.
Should it be necessary to adjust for more or less drop of picture, proceed in the following manner:
1. Remove the two screws holding the junction box cover. Located
on the left end of the case (see Figure 1).
2. Unplug the 6P6C wire that is plugged into the secondary splitter
"QEYE" port (see wiring diagram).
3. Unplug the 6P4C wire from the Operating Keypad at the wall.
Plug the 6P4C wire into the Limit Setting Switch. The LED on the
back of the Limit Setting Switch will blink green twice.
4. If adjusting the screen limit, the 6P4C cable will need to be
plugged into the "QEYE" port of the primary splitter. If adjusting
the mask limit it will need to be plugged into a "QEYE" port on the
secondary splitter.
5. Press and hold both the Up and Down Limit Switch on the back
of the Limit Setting Switch until the LED blinks red twice.
6. To adjust the down limit, press and hold the Down tactile button
until the LED on the back of the Limit Setting Switch turns solid
red. This will put the motor in limit set mode. Turn the switch over
and use the Down button on front of switch. Press and hold until
the desired travel position is reached. If you travel too far down,
press the UP button to move the screen upward. If you press and
let go of either the UP or DOWN button, the motor will do a small
jog in that direction for finer adjustment of the screen. Once the
desired position is reached, turn the switch over and press and
hold the DOWN tactile button until the LED on the back of the
switch blinks red twice. The down limit is now set.
7. To adjust the up limit, press and hold the UP tactile button until
the LED on the back of the Limit Setting Switch turns solid green.
This will put the motor in limit set mode. Turn the switch over and
use the UP button on front of switch. Press and hold until the
desired travel position is reached. If you travel too far up, press
the DOWN button to move the screen downward. If you press
and let go of either the UP or DOWN button, the motor will do a
small jog in that direction for finer adjustment of the screen.
Once the desired position is reached, turn the switch over and
press and hold the UP tactile button until the LED on the back of
the switch blinks green twice. The down limit is now set.
8. To test limit switch settings, press and release the UP or DOWN
button on the Limit Setting Switch to operate the screen.
9. Press and hold both the UP and DOWN tactile buttons on the
back of the Limit Setting Switch until the LED blinks red twice.
10. Unplug the 6P4C cable from the limit switch and plug it back into
the Operating Keypad.
11. Plug the 6P6C connector back into the "QEYE" port of the
secondary splitter and replace the splitter junction box cover.
Intermediate Positions.
The motors on the Horizon Electrol® have been preset to three or four different screen formats based on your screen size. See the
Screen Operation section for the standard screen formats. It is possible to adjust these format for your particular needs. The following
instructions will walk you through this process.
(See Motor Limit Adjustments to adjust the stop positions for all the way up or all the way down positions)
1. Press the screen down button on the wall keypad or remote.
When the screen reached the desired position, press the stop
button. If you go past the desired position, press the stop button
and then press the up arrow to return the screen to a position
above the new stop point and try again until the screen stops at
the new position.
2. Press the mask down button on the wall keypad or remote.
When the mask reached the desired level, press the stop button.
If you go pas the desired position, press the stop button and
