24 114A2845 Without a properly installed safety reversal system, WWARNARNINGINGCAUTIONCAUTION WWARNARNINGINGCAUTIONCAUTION ADJUSTMENT STEP 1 Limit Adjustment Run the opener through a complete travel cycle. Force adjustments are not necessary when the door opens and closes completely and doesn't reverse unintentionally in the fully closed position. Locate the button on the back panel of motor unit. NOTE: if the operator stops or reverses and will not allow the run through of a complete travel cycle, it may be necessary for the operator to adjust the force profile. Push the button twice to enter into Force Setting Mode. Proceed with limit setting. NOTE: Repeated operation of the opener during adjustment procedures may cause motor to overheat and shut off. Allow a 15 minute cooling period after 5 continuous operations of the opener. Read the following carefully before proceeding to Force Adjustment. Use a screwdriver to make limit adjustments. If Door Doesn't Open Completely but Opens at Least 1.5m (5 feet): Increase up travel. Turn the up limit adjustment screw clockwise. One turn equals 5cm (2") of travel. If door does not open at least 1.5m (5 feet). Adjust force, see Force Adjustment: Place the opener into the Force Adjustment Mode, see Force Adjustment. If Door Doesn't Close Completely: If door arm is at maximum length, increase down travel. Turn down limit adjustment screw counterclockwise. One turn equals 5cm (2") of travel. If the door still will not close completely, the header bracket is positioned too high. If Opener Reverses in Fully Closed Position: Decrease down travel. Turn down limit adjustment screw clockwise. One turn equals 5cm (2") of travel. If Door Reverses when Closing and there is no Interference to Travel Cycle: Test door for binding. Pull manual release handle. Manually open and close door. If door is binding, call a door serviceman. If door is not binding or unbalanced, place the opener into the Force Setting Mode, see Force Settings. PROCEED TO “FORCE SETTINGS” TO COMPLETE STEP “LIMIT ADJUSTMENT”. Forces must be learned in order for limit adjustments to operate properly. persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. • Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system. • If one control (force or travel limits) is adjusted, the other control may also need adjustment. • After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 40mm high object on floor. prevent damage to vehicles, be sure fully open door provides adequate clearance. WWARNARNINGINGCAUTIONCAUTION 114A2845 25 Without a properly installed safety reversal system, WWARNARNINGINGCAUTIONCAUTION WWARNARNINGINGCAUTIONCAUTION ADJUSTMENT STEP 2 Adjust the Force The force, as measured on the closing edge of the door, should not exceed 400N (40kg). If the closing force is measured to more than 400N, a Safety Infrared Reversing Sensor must be installed See step 3 on page 27. The force setting button is located on the back panel of the motor unit. The force setting regulates the amount of power required to open and close the door. If the forces are too light, door travel may be interrupted by nuisance reversals. Locate the button on the back panel of motor unit. Push the button twice to enter into Force Setting Mode. The LED (Indicator Light) will flash. Push the wall control or the programmed remote control that was shipped with your opener. The door will travel to either the OPEN or CLOSE position. Push the button again, the door will travel to the opposite position. Push the button again if the LED is stilling blinking. The door must travel through a complete cycle UP and DOWN in order for the force to be set properly. If the unit reverses before it reaches the Open or Close Limit repeat the process. The LED (indicator light) will stop flashing when the force has been learned. Note: If unable to set limits return to page 25. persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. • Too much force on garage door will interfere with proper operation of safety reversal system. • NEVER increase force beyond minimum amount required to close garage door. • NEVER use force adjustments to compensate for a binding or sticking garage door. • If one control (force or travel limits) is adjusted, the other control may also need adjustment. • After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 40mm high object on floor. • The force, as measured on the closing edge ot the door, should not exceed 400N (40kg). If the closing force is more than 400N, a Safety Infrared Reversing Sensor must be installed. Do not use the force setting procedure to compensate for a binding or sticking garage door. Excessive force will interfere with the proper operation of the Safety Reverse System or da...
