Door Speed Adjustments
The door cylinder has integrated speed controls.
Door speeds should be set to allow the doors to
open and close smoothly. Repetitive slamming
may damage the doors.
closing speed
Door closing speed can be adjusted using a screw
on the front cap of the door motor (refer to item
7
in Figure 11-22 and the circled area of Figure
11-26 ). To adjust closing speed, first loosen the
jam nut, then turn the screw. Turning the screw in
slows the closing speed, while turning the screw
out increases closing speed. Tighten the jam nut
when closing speed is adjusted satisfactorily.
door cushioning
To prevent the doors from slamming against the
stops during opening, adjust the cushioning using
the screw on the rear cap of the door motor (refer
to item
6
in Figure 11-22 and the circled area of
Figure 11-27). The cushioning screw can be found
behind the left end of the closing spring. To adjust
cushioning, first loosen the jam nut, then turn the
screw. Turning the screw in increases cushioning,
while turning the screw out provides less cushion-
ing. Tighten the jam nut when cushioning adjust-
ment is complete.
opening speed
The speed at which the doors open is governed by
the door control valve, located on top of the door
motor (refer to item
9
in Figure 11-22 and the
circled area of Figure 11-28). Adjusting this valve
determines the rate of airflow into the door mo -
tor. Turn the valve clockwise to slow the opening
speed; turning the valve counterclockwise makes
the doors open faster.
