FINAL ADJUSTMENTS

LEVELING DOOR PANEL

1. To check a door panel for level, first position the
panel so that it is approximately four or five feet off
the floor. Then check the bottom edge of the door
panel for level. (The panel is considered level when
both sides are within ¹/₄ in. of each other.)
NOTE: Do not check the door panel for level by
visually observing how it rests on the floor.
Level is referred off the two side columns
and the head assembly.
2. Before making any adjustment to the door, remove
all electrical power to the control panel.
The disconnect must be in the OFF posi-
tion and properly locked and tagged before
performing the following procedure.
3. Mounted on the bottom corner of the door is an end
bracket (one in each corner). This bracket is
clamped around the two ends of the drive belt.
(See Figure 56.)
NOTE: If the door requires adjustment, always
lower the high side of the door and never
lower the door more than two notches at a
time. Also, a reference mark on the drive
belt will make it easier to return the end
bracket to its original location, should that
become necessary.

4. On the side that needs to be lowered, place your
hand on the smooth side of the secondary drive belt
and begin moving your hand up the belt towards the
head assembly. When you're near the top, a wave will
form and the belt will slip or jump on the sprocket.
Perform this process until the panels have reached
level. DO NOT place your hand between the belt and
the sprocket while performing this task. (See Figure
59.)
5. Restore power to the control panel and cycle the
door several times. Recheck the panel for level and
repeat the above steps, as necessary, until the
panel is level.

TESTING REVERSING EDGE

Take precautions to prevent someone else
from operating the door as you perform
the following procedure. Also, be cautious
around the moving parts that are exposed
in the side columns.
With the door fully open, press the door close (▼)
button. As the door begins to come down, test the
door reversing edge by hitting the bottom (rubber)
edge of the door. (See Figure 57.)
The reversing edge sensor is working correctly
when the door reverses direction to the fully open
position. If the reversing edge is impacted three
consecutive times the door will remain open until
the system is reset.
1. To reset the control system with "F.361"
displayed, first make sure the area directly below
the path of the door is clear of all objects and
personnel.
2. Then press and hold the Reset (●) button
until the control reads automatic.
3. Press the door close (▼) button to move the
door to the fully closed position.
NOTE: Avoid tripping the photo eye sensors when
testing the reversing edge.
