PowerMaster H User 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 proper
response for your installation.
Observe the door when traveling in each
direction for smoothness of operation. Test the
setting of the clutch (if equipped) 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.
Model H & J operators are equipped with a
reversing edge circuit for use with 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).
If the operator is equipped with other means of
TESTING
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 or using the hoist chain. 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.
