1 GATE LIMIT RELAY KIT INSTALLATION INSTRUCTIONS GATE OPERATORS: SW420/470/490, SL540/570/580/590 PARTS SUPPLIED Part # Qty Description Modification Instructions Cable Tie Relay Assembly Quick Tap Connector Tube, Vinyl (Single Button Apps.) WARNING To prevent possible SERIOUS INJURY:! TURN OFF operator power before you begin working inside the unit. Relay Kit Applications The Gate Limit Relay Kit may be used in any of the following applications:! Single Button Control! Shadow Loop! Courtesy Light Preparation During the installation, refer to the corresponding figure for S3 board and Radio terminal locations that match your operator (see page 2). 1 Remove access panel or cover from operator. 2 Turn off the operator power switch. Relay Installation 1 Locate an empty area inside the operator near the Radio terminal (R2) and the S3 controller board. This is the area where you will install the relay. Make sure that the selected area is close enough for the relay s wires to reach the Radio terminal and the S3 controller board. 2 Clean the area of dust and dirt. Use alcohol to clean the area. 3 Peel off protective tape from velcro (bottom of relay). Then firmly press the relay against the selected area. Wire Tapping When the instructions call for you to tap wires, refer to Figure 2.

3 Single Button Operation and Wiring The Gate Limit Relay Kit modifies the radio input, allowing a radio control, such as a remote transmitter, to open and close a gate. RELAY TO S3 BOARD CONNECTION 2 Give the operator an open command to fully open the gate. 3 TURN OFF operator power switch. 4 Route relay Gray, Green, and Blue wires to connector J1 and J2 on S3 controller board. 5 Connect Gray wire to terminal J Connect Green wire to terminal J Locate the Open Limit switch by looking for which switch is being pressed by its cam. Find which wire (Orange or Purple) is connected to the switch. If Orange wire is connected to Open Limit switch, using the provided tap connector, connect the Blue relay wire to the Orange wire going to terminal J2-8 on the S3 board (see Figure 2). If Purple wire is connected to Open Limit switch, using a provided tap connector, connect the Blue relay wire to the Purple wire going to terminal J2-7 on the S3 board (see Figure 2). Figure 9: Single Button Wiring Schematic Page 3 of 6 RELAY TO RADIO TERMINAL (R2) CONNECTION 1 Route relay Red and Brown wires to Radio terminal inside the operator. 2 Remove the existing Brown wire from terminal R2 and insert through the plastic tubing (supplied); then connect to relay Brown wire terminal. Pull tubing over the wire terminals to cover bare terminal sections. 3 Connect relay Red wire to terminal R2. Relay Assembly (Supplied) Front View F1 Figure 10: Single Button Wire Routing TEST THE SINGLE BUTTON OPERATION Before you start, review the wiring carefully. Then secure the wires to the harness assembly using the supplied cable ties. 1 Set SW1-1 on S3 board to ON (close); refer to Figure 1 and Figure 11. Then TURN ON operator power switch. 2 Activate your radio transmitter and verify that the open gate closes and that the closed gate opens. NOTE: Activating radio transmitter must have no effect during gate opening and must open the gate furing gate closing. 3 Re-install access panel or the cover on the operator.

4 Page 4 of 6 Shadow Loop Operation and Wiring The Gate Limit Relay Kit allows the Safety Loop input to be used with Shadow Loops. When activated by a vehicle, a Shadow Loop prevents a fully open gate from closing. It has no effect if gate is closed or between the limits. RELAY TO S3 BOARD CONNECTION 2 Give the operator an open command to fully open the gate. 3 TURN OFF operator power switch. 4 Disconnect the Brown wire from the relay assembly. NOTE: Brown wire can be used in relay to shadow loop connection (see below). 5 Route relay Gray, Green, and Blue wires to connector J1 and J2 on S3 controller board. 6 Connect Gray wire to terminal J Connect Green wire to terminal J Locate the Open Limit switch by looking for which switch is being pressed by its cam. Find which wire (Orange or Purple) is connected to the switch. If Orange wire is connected to Open Limit switch, using the provided tap connector, connect the Blue relay wire to the Orange wire going to terminal J2-8 on the S3 board (see Figure 2). If Purple wire is connected to Open Limit switch, using a provided tap connector, connect the Blue relay wire to the Purple wire going to terminal J2-7 on the S3 board (see Figure 2). RELAY TO SHADOW LOOP DETECTOR CONNECTION 1 Connect relay Red wire to Shadow Loop Detector s normally open relay contact. 2 Connect Brown wire from Shadow Loop Detector s common relay contact to Terminal R1 (or J1-5). Figure 12: Shadow Loop Wiring Schematic TEST THE SHADOW LOOP OPERATION Before you start, review the wiring carefully. Then secure the wires to the harness assembly using the supplied cable ties. 2 Give an open command to fully open the gate, if the gate is not already fully open. 3 Activate the Shadow Loop by placing a large metallic object (large can, tool box, etc.) on the Shadow Loop. Be ready to remove the oject if gate starts to close. 4 Give a close command for the operator to close the gate. Verify that the gate does not close while the object is on the loop. 5 Remove the object and repeat steps 2 through 4 using a vehicle as metallic object. 6 Remove vehicle and re-install access panel or the cover on the operator.

5 Courtesy Light Operation and Wiring The Gate Limit Relay Kit can be used to accommodate a courtesy light. When the gate opens, the courtesy light turns on and lights up the gate area. The relay can accommodate up to 10A at 110VAC or 24VDC. RELAY TO S3 PCB CONNECTION 1 Make sure that the gate is fully closed. 2 TURN OFF operator power switch. 3 Disconnect the Green wire from the relay assembly. 4 Route relay Gray and Blue wires to connector J1 and J2 on S3 controller board. 5 Connect Gray wire to terminal J Locate the Close Limit switch by looking for which switch is being pressed by its cam. Find which wire (Orange or Purple) is connected to the switch. If Orange wire is connected to Close Limit switch, using the provided tap connector, connect the Blue relay wire to the Orange wire going to terminal J2-8 on the S3 board (see Figure 2). If Purple wire is connected to Close Limit switch, using a provided tap connector, connect the Blue relay wire to the Purple wire going to terminal J2-7 on the S3 board (see Figure 2). RELAY TO COURTESY LIGHT CONNECTION WARNING To prevent possible INJURY:! SHUT OFF the courtesy light power circuit before wiring connections. Page 5 of 6 Figure 14: Courtesy Light Wiring Schematic TEST THE COURTESY LIGHT OPERATION Before you start, review the wiring carefully. Then secure the wires to the cabinet using the supplied cable ties. 2 Give an open command for the operator to open the gate. Verify that the courtesy light stays on as long as gate is not fully closed. 3 Re-install access panel or the cover on the operator. Cut off terminals from relay Red and Brown wires; then connect wires to courtesy light and circuit power using wire nuts (see Figure 13).
