ADJUSTMENTS RIGHT OR LEFT HAND OPERATION UNIT SHIPS AS RIGHT-HAND RIGHT HAND OPERATION Method 1: No longer used as of August 16, 2003. The S1-7 AUX. LIMITS OF FUSE F3 switch will be redefined. Green (Open & Close Limits) MOV MOTOR Method 2: Reverse the BLUE and ORANGE wire from the Orange motor and at J4 from the limit switches. With this method Blue DO NOT switch S1-7 to the ON position - leave in OFF position. BAT+ 24VAC XFMR MOTOR Orange RIGHT HAND OPERATION the motor (J4) and limit switch (J2) wires will be BLUE then ORANGE NOTE: Right hand operation is the default setting from the factory. LEFT HAND OPERATION the motor (J4) and limit wires (at J2) will be ORANGE then BLUE. As a RIGHT HAND OPERATOR the LIMIT SWITCH closest to the gear box is the CLOSE LIMIT. As a LEFT HAND OPERATOR the LIMIT SWITCH closest to the gear box is the OPEN LIMIT. Green Blue Orange LIMIT SWITCH ADJUSTMENTS Disconnect power from operator. In order to adjust limit nuts, the detent plate must be pushed down to allow free movement. Spinning the nut closer to the switch will cause the gate to stop sooner when approaching that switch. Spinning it away will delay the nut in reaching that switch. With power disconnected, (batteries and ac power) gate can be pushed open and closed to assist in limit switch adjustments. After initial settings connect power then run gate open and close to fine tune settings. Remember to set the fast run timer (page 13) to allow gate to run at the fast speed for as much of the gate travel as possible, but still ensuring that it will slow down just before reaching the closed position. 1 AUX LIMITS J2 D1Ø S1 S2 1 2345678 1 OR AUX.

Gate Open Operator Righthand operation is viewed from the same side of the gate as the operator with the operator to your right. INSTANT REVERSE DEVICE (IRD) WARNING The reverse device is an internal circuit that continuously monitors the motor's current for increased draw. This operator has been shipped with the IRD1 set to a typical setting that will likely move the gate from limit to limit. If necessary, the sensitivity of this device can be adjusted by turning the IRD1 to the right (CW, more sensitive) or left (CCW, less sensitive) in small increments. To prevent possible SERIOUS INJURY or DEATH: CAUTION • After ANY adjustments, verify that the operator reverses off a rigid obstruction located 1' from both the open and close limits. • Test instant reverse device (IRD) monthly. • Adjustment MUST be made by qualified service personnel. ADJUSTMENT While running the gate open and closed, verify that the gate travels as expected. Verify that the operator reverses off a rigid obstruction located 1' from both the open and close limit. If the operator does not reverse, adjust the IRD1 CW (more sensitive) in small, 1 hour increments until the gate reverses off the 1' obstruction. The gate should continue to travel from the open and closed limits as expected. ESS SENSITIVE C7 MORE SENSITIV If the gate did not complete the full open and closed travel, the IRD1 setting should be incremented CCW (less sensitive) in small, 1 hour increments until the gate travels the full distance. Verify that the operator reverses off a rigid obstruction located 1' from both the open and closed limit.

If during the setup, a double entrapment condition occurs, refer to the troubleshooting section to rest the gate. 14 L 7 5 6
