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 in the path of 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 proper
response for your installation.
Observe the door when traveling in each direction
for smoothness of operation. Test the setting of
the clutch by restraining the door, DO NOT USE
YOUR BODY TO DO THIS. The clutch should
slip. Re-check the limit settings. The door should
close tightly without excessive impact. Likewise, it
should fully clear the door opening without the
trolley traveler coming too close to the power
head.
To test a safety edge for proper reversal, place an
object in front of the path of travel of the door so
the edge being tested strikes the object. The door
should instantly reverse when it comes into
contact with the object, provided the opening of
the door exceeds the cut out point built into the
close limit switch (approximately four inches).
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 is
possible when the release cord is pulled and the
door plunger releases from the trolley traveler. If it
is difficult to disengage or engage the door arm
assembly at the closed position because the
chain appears to be under compression, reset the
CLOSE limit slightly to reduce the door travel in
the close direction.
DO NOT STAND IN FRONT OF DOOR TO
TEST REVERSING EDGE. USE A
CORRUGATED BOX OR SIMILAR OBJECT.
