Owner's Manual

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 edge or foam edge door components. To test it for
proper reversal, place an object beneath the leading edge of the
door. 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
(approximately four inches).

TESTING
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.
To test the manual disconnect first move the door to the fully
closed position. Then disconnect the power to the operator.
Manual door operation mode should engage when the release
chain is pulled. The door can then be manually opened or
closed by physically moving the door (Model M50JF) or using
the hoist chain (Model M50JH). If it is difficult to engage and/
or the jackshaft to doorshaft chain appears to be under
compression, reset the CLOSE limit slightly to reduce the door
travel in the close direction.
ALWAYS DISCONNECT POWER TO
THE OPERATOR BEFORE SERVICING,
CONNECTING ACCESSORY DEVICES
OR MAKING ADJUSTMENTS.
