Section 6 -
Limit Adjustments
(Standard Motor)
Please Note:
Screen limits are factory set for optimum performance of screen. Any adjustment of these limits could void warranty. Please check with Draper prior to
resetting screen limits.
CAUTION:
Always be prepared to shut screen off manually when new adjustment is being tested. Screen may be severely damaged if viewing surface is allowed to run
too far up or too far down.
CAUTION:
Be sure all switches are in “off” position before adjusting limit switches.
1.
Adjusting “fully up” position —If you do, however, “Up” stopping position may be adjusted by turning yellow limit switch adjustment socket. The yellow socket is located on left end
of screen roller and is accessible to a screwdriver/Allen wrench
(4mm or
5
/
32
")
. Turning socket counterclockwise will allow viewing surface to retract farther into case. Turning it
clockwise will cause surface to stop farther out of case. One full revolution of socket will alter stopping position of viewing surface by approximately 38.1mm.
2.
Adjusting “fully down” position — “Down” stopping position may be adjusted by turning white limit switch adjustment socket. The white socket is located on left end of screen roller
and is accessible to a screwdriver/Allen wrench
(4mm or
5
/
32
")
. Turning socket counterclockwise will allow viewing surface to run farther down. Turning it clockwise will shorten
viewing surface, causing it to stop in a less extended position. At no time should viewing surface be unrolled enough to expose any part of screen roller.
