The red indicator and the operators light will flash two times. NOTE: If the operator is Field Reset (see pg. 14), both the open and close limits must be adjusted and the automatic door force setup must be completed for proper operation. Automatic Door Force Setup The operator automatically measures the door force throughout the entire travel of the door each time the operator cycles. The following steps are all thats required to setup the safety reversal system. a) Be sure that the trolley latch is up, and the door is connected to the operator. b) After limits have been set, you may begin using the operator. The learning process will be complete after the fourth cycle. CAUTION Do not cycle the operator full travel without the door connected . The automatic door force setting will adjust to the unloaded condition and may trip the safety system when the door is reconnected . 6 b POWER DOWN (-) LEARN UP(+) BEAMS WALLSTATION COMMON c DOWN UP EXAMINE THE LOCATION WHERE THE DOOR OPENS UP c DOWN 4 EXAMINE THE LOCATION WHERE DOOR CLOSES 4 b Safety Reversal System Test The operator determines if there is an obstruction if a higher than expected amount of force is detected during a door cycle. If an obstruction is encountered during a closing cycle, the operator and door will stop then fully open. If an obstruction is encountered during an opening cycle, the operator and door will stop. a) Lay a 2 x 4 board flat on the floor where it will be struck by the center of the door as it closes. b) Verify that the door reverses when it strikes the board. The door must reverse within two seconds after striking the board. WARNING Always perform the Safety Reversal System Test after making any adjustments to the operator . PERFORM THE SAFETY REVERSAL SYSTEM TEST MONTHLY!

b a Adjusting the Force Factor (Installation Option, Normally Not Used) The operator uses the peak force measured during each of the last four complete cycles plus a force factor to calculate the maximum allowed force setting for the current door cycle. If the calculated maximum force setting is exceeded during the current door cycle, the operator reacts to the obstruction. As door hardware conditions change over time with weather and wear, the calculation of the maximum door force setting using the four cycle running average will compensate for the current conditions of the installation. The door force is preset for the lowest amount of pressure on an obstacle to detect an obstruction . THE FACTORY SETTING IS OPTIMIZED FOR MOST INSTALLATIONS . Changing the Force Factor Setting As an installation option, the operators force factor can be adjusted to change the amount of pressure exerted on an obstacle before the operator reacts to the obstruction. a) Press both the UP and DOWN buttons for three seconds. The red and green indicators and operators light will flash twice. b) Use the UP or DOWN buttons to set the force factor. Pressing the UP button increases the force factor, pressing the DOWN button decreases the force factor.

Doors may swell and become heavier during wet periods, door hinges and rollers might bind during cold periods. To insure safe operation of the door, perform the following tests, including any additional test steps described. Aligning the Infrared Safety Beam The safety beam has two components, a sender and a receiver. The sender produces a narrow infrared beam that travels across the bottom of the door opening to the infrared receiver. If an object blocks the infrared beam while the door is closing, the door will stop, then reverse and fully open (the operators light will flash three times). As a safety feature, the operator will not attempt to close if the door is open and the infrared safety beam is blocked or out of alignment . In this case, the door can be forced closed by pressing and holding the wall station pushbutton (be sure the door area is in clear view) . WARNING With the door closed, disengage the trolley from the chain or belt during these alignment tests by pulling the red release handle . WARNING Serious injury or death from a closing garage door may result because of failure to test and adjust safety reverse system . Repeat this test monthly and adjust as needed . Safety Beam a) Check that the operator has power. The green lights on the sender and receiver should be lit. RED LIGHT GREEN LIGHT b) If the receivers green light is on (but the red light is off) the receiver has power, but its not detecting the infrared beam from the sender. The red light might flash when the beam is partially detected. This can be caused by misalignment or something blocking the beam. Adjust the safety beam sender and receiver while watching the receivers red light (stay out of the beam while aligning it). c) When the red light stays on, rotate the sender towards the ceiling and stop when the red light on the receiver begins to flicker. d) Rotate the sender back towards a horizontal position with the floor and stop as soon as the red light on the receiver lights solid. The beam is now properly aligned. d GREEN ON GREEN OFF RED ON SAFETY BEAM INDICATOR TABLE POWER ON POWER OFF BEAM OK - NO BLOCKAGE BEAM BLOCKED OR MIS-

ALIGNED RED FLASHING BEAM ALIGNED POORLY RED OFF NOTE: If the receivers red light remains off, check for: 1) Dirt on the receivers lens, 2) Sunlight shining into the receivers lens, 3) A short in the safety beam wiring (from staples or at the operator terminals). 12 Checking for Reversal a) With the door closed and the operator disengaged from the door, press the wall station button to move the traveler (the part on the belt or chain that the trolley engages with) to the up position

(away from the door). NOTE: Do not cycle the operator to full travel without the door connected . b) Push the wall station button again. While the traveler is moving to the down position (toward the door), block the safety beam. THE TRAVELER MUST STOP, THEN REVERSE TO THE UP POSITION . The operators light and red light should flash three times. Checking Forced Closure Feature a) Place an object in the path of the safety beam. Check that constant pressure is required on the wall station button to cause the traveler to move toward the down position. b) Release the Wall Station button before the operator stops; check that the traveler returns to the up position. NOTE: The garage door operator will not respond to a CLOSE command from a radio transmitter if the safety beam is blocked. c) To reconnect the operator, flip the release lever up. Raise the door manually until the operator reconnects. d) To reconnect the operator, flip the release lever up and run the operator. e) Check Safety Beam operation (p. 12). f) Perform the Safety Reversal System Test (pg. 7). After Servicing the Operator a) Check Safety Beam operation (pg. 12). b) Perform the Adjusting the Open and Close Limits (pg. 6). c) Perform the Safety Reversal System Test (pg.15). Every 6 Months Check the belt or chain tension. For belt-drive rails, examine the length of the tension spring in the traveler. It should be about 1 long. For chain-drive rails, examine the spacing between the turnbuckle and the rail. The turnbuckle should be slightly above the rail. NOTE: Too much or too little chain tension will cause excessive sprocket noise. DOWN UP a TOWARD OPERATOR TOWARD DOOR TRAVELER b b a WARNING The garage door operator must not be installed and used on an unbalanced door . The operators internal door force sensor will not function properly on an unbalanced door . Risk of serious injury or death may result . NOTICE IF DOOR BECOMES OBSTRUCTED, PULL DOWN ON HANDLE NOTICE IF DOOR BECOMES OBSTRUCTED, PULL DOWN ON HANDLE WARNING Always perform the Safety Reversal System Test (pg . 15) after making any adjustments to the operator . 13 Chain Adjustment If necessary, use the following steps to adjust the chain. a) Hold the turnbuckle with a flat blade screwdriver, and loosen the two lock-nuts with a 7/16 end wrench. b) Twist the turnbuckle to adjust the chain tension. Adjust the chain until the turnbuckle is sightly above the rail. LOCKNUTS LOOSEN c) Hold the turnbuckle with a flat blade screwdriver and tighten the two TO HEAD lock-nuts with a 7/16 end wrench.
