TUNING OF MOTOR GEARBOX
Door Stop Set
– Windy Conditions
Set the door to mechanically open to 110 to 115 degrees and have the door stop electronically at 90 to 95
degrees by tuning the back check speed to maximum (clockwise). The doors will time out at 90 degrees.
If a strong wind gust occurs the door will have an additional 10 to 15 degrees of movement to shear the
effect.
Back check and Latching
To set back check
1. Open the door to the fully open position magnet #1 (lower magnet) should cross over the back
check switch (where
grey wire
conductor plugs into green circuit board) engaging back check
speed 10 degrees prior to the door reaching fully open. The control board slows the door to a
gently stop at the fully open position. Doors shall be adjusted so back check will not occur before
60 degrees of opening (maximum, preferred at 10 degrees before full open)
To set the latch
2. When the door is in the close position, magnet #2 (upper magnet) should be over the latch reed
switch. This magnet signals the controller to slow the closing door speed before stopping at the
latch or doorstop.
