WARNING
TO AVOID RISK OF ENTRAPMENT AND
POSSIBLE DAMAGE TO THE DOOR AND
OPERATOR THE LIMITS MUST BE ADJUSTED
BEFORE APPLYING POWER TO THE
OPERATOR.
SETTING THE LIMIT SWITCHES
1) With the cover open on the electrical enclosure, reference
Figure 14 below. There are four (4) switches (A, B, C, and D)
mounted to the ‘V’ bracket (H). The limit switches are
mounted in a fixed position to the underside of the ‘V’ bracket;
with the Close Limit switch (B) on the right and the Open
Limit switch (D) on the left. The Reverse Cutout switch (A)
and the Single Button Selector switch (C, also could be Timer
Engage switch depending on the model) are mounted to the top
side of the ‘V’ bracket as shown. The switches are activated by
the two limit nuts (E & G) on the threaded shaft which move
laterally along the shaft as the operator opens and closes the
door. When a limit nut nears the end of the shaft it activates a
set of switches, upper switch first then the lower fixed limit
switch.
2) Depress the Limit Nut Retention Plate (F) so it disengages
from the slots in the limit nuts and move the Limit nuts to the
center of the threaded shaft.
3) Manually raise the door to a nearly open position.
4) Depress the limit nut retaining bracket (F) so it
disengages from the slots in the limit nuts. Turn the OPEN
limit nut (E) on the shaft until it engages both the Single
Button Selector switch (C) and the Open Limit Switch (D).
You will need to listen for two audible clicks. Release the
retaining bracket and be sure that it engages in slots of both
limit nuts.
5) Manually lower the door to the fully closed position and
repeat Step #3 with the Close Limit nut (G) and Reverse
Cutout switch (A) and the Close Limit switch (B).
6) Manually move the door to a half open position. With
the door in a mid position there will be time to stop the door
if something or someone were in the door path when initially
starting the door.
7) A final limit adjustment will be necessary after the
connection of the power supply in order to ensure the door
stops at the proper Open and Close positions.
8) Adjustment of the Reverse Cutout switch (A) or Single
Button Selector switch (C) is done at the factory and should
not be needed in the field. Moving the Reverse Cutout
switch closer to the center of the box will increase the point
where the reversing feature cuts out (to allow for irregularity
in the floor, etc.). The reverse cutout point is factory
adjusted to approx. 4 inches off the floor.

TESTING
Following installation, the operator MUST be tested and
respond correctly to all controls as specified on the wiring
diagram. Keep personnel and equipment clear of the area
beneath the door when performing the tests. When testing the
3-button wall station, first observe that each button operates the
door in the direction indicated and that the STOP button
performs that function. With the door stopped at its full open
position, the OPEN button should be inoperative. This should
be verified and, likewise, the CLOSE button should be
inoperative with the door fully closed.
Certain operator control circuits use only a single button or a
two button control station and may be designed to function
differently than the more common three-button circuit
described above. Test the controls in accordance with the
description of operation as indicated on the wiring diagram.
Observe the door when traveling in each direction for
smoothness of operation. Test the setting of the clutch by
restraining the door by hand. The clutch should slip. Re-check
the limit settings. The door should close tightly at the floor
without excessive impact. Likewise, it should fully clear the
door opening without the carrier striking the stops on the rail.
The M series operators are equipped with a reversing edge
circuit and to conform with code, need to be connected to a
pneumatic or foam door edge or photoelectric device. To test an
edge for proper reversal, place an object beneath the leading
edge of the door. To test a photoelectric device for proper
reversal, start the door down and obstruct the beam. The door
should instantly reverse when it comes into contact with the
object provided the height of the object exceeds the cut out
point built into the close limit switch (approx. four (4) inches).
CAUTION
DO NOT STAND UNDER DOOR
TO TEST REVERSING EDGE
USE A CORRUGATED BOX
OR OTHER SIMILAR OBJECT
If the operator is equipped with other means of control, such as
additional 3 button stations or radio controls, each of these should
be tested separately for proper operation.
Test the manual disconnect with the door in the fully closed
position. The door arm should freely fall away from the carrier
when the release chain is pulled. If it is difficult to release and the
door arm appears to be under compression, reset the CLOSE limit
slightly to reduce the travel of the carrier in the close direction.
WARNING
ALWAYS DISCONNECT POWER TO
THE OPERATOR BEFORE SERVICING,
CONNECTING ACCESSORY DEVICES
OR MAKING ADJUSTMENTS.

MAINTENANCE
Normally, very little maintenance is required. A monthly visual
inspection must be made for loose or missing hardware and for
excessive slack in the V-Belt and drawbar chain. The clutch
must be tested periodically and adjustments made if necessary
(see page 15). The brake (where applicable) is adjusted at the
factory and will need periodic adjustment for wear. When
adjustment becomes necessary see Figure 18 on page 16 for
the adjustment procedure.
Test the reversing edge circuit at least once a month by
permitting the door to contact an obstruction while closing. To
test a pneumatic or foam door edge for proper reversal, place an
object beneath the leading edge of the door. To test a
photoelectric device for proper reversal, start the door down
and obstruct the beam. The door should instantly reverse when
it comes into contact with the object provided the height of the
object exceeds the cut out point built into the close limit switch
(approx. four (4) inches).

Lubrication of the operator is not required. It is important, for
trouble free service from the operator, that the door be kept free
from binding, properly counter balanced and periodically
lubricated. An annual inspection of the door by a qualified
overhead door professional is recommended.
Warning: Repairs and adjustments to the door and operator
should be performed only by someone qualified to service
commercial overhead doors and operators.
