22	OPERATION & ADJUSTMENT INSTRUCTIONS
	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 and as selected on pages 17, 18, and 19, OPERATING and SET-UP MODES.

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 AUJ-S and AUH-S series operators are equipped with a reversing circuit and to allow for Momentary Close Contact operation an approved entrapment protection device as described on Page 3 needs to be properly installed and connected to the operator. 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).

CAUTION

DO NOT STAND UNDER DOOR TO TEST REVERSING FEATURE 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 AUJ-S) or using the hoist chain (Model AUH-S). 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.

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 jackshaft chain. The clutch must be tested periodically and adjustments made if necessary (see page 20). The brake is adjusted at the factory and will need periodic adjustment for wear. When adjustment becomes necessary see Figure 14 on page 19 for the adjustment procedure.

Test the reversing edge circuit at least once a month by permitting the door to contact an obstruction while closing.

CAUTION

DO NOT STAND UNDER DOOR TO TEST REVERSING

EDGE - USE A CORRUGATED BOX

OR OTHER SIMILAR OBJECT

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.
