INSTALLATION STEP 10 continued... DUAL GATES ONLY WIRED DUAL GATES Before digging, contact local underground utility locating companies. Use PVC conduit to prevent damage to cables. Disconnect ALL power to the operator and unplug the J15 plug from the control board. 1. Trench across driveway to bury the shielded twisted pair cable. 2. Connect the wires from the shielded twisted pair cable to the Com Link terminals on the primary gate operator control board. NOTE: We recommend that all accessories and board configurations are set on the primary operator. 3. Route the shielded twisted pair cable to the secondary gate operator's control board. 4. Connect the wires from the shielded twisted pair cable to the Com Link terminals on the secondary control board (Com Link A to Com Link A and Com Link B to Com Link B). Ground the shield of the cable to the chassis ground of one operator. Connect ALL power to the operator and plug the J15 plug into the control board. DUAL GATE WIRE TYPE (SHIELDED TWISTED PAIR CABLE) 22AWG up to 200 feet (61 m) 18AWG - 200-1000 feet (61-305 m) Wire must be rated at 30 Volt minimum Com Link Data A Com Link Data B Com Link Data A Com Link Data B COM LINK BA BIPART DELAY/SYNCHRONIZED CLOSE The LOCK/BIPART DELAY switch is used only with dual gate applications and serves two functions: • BIPART DELAY SWING GATE APPLICATIONS: The BIPART DELAY is used in applications where a mag-lock, solenoid lock, or decorative overlay would require one gate to close before the other. The operator with the LOCK/BIPART DELAY switch ON will delay from the close limit when opening and be the first to close from the open limit. SLIDE GATE APPLICATIONS: Not applicable, set to OFF. AC & BATT FAIL BACKDRIVE • SYNCHRONIZED CLOSE The BIPART DELAY is also used in applications where one gate travels a longer distance than the other. To synchronize the closing of the gates, set the LOCK/BIPART DELAY switch to ON for both operators. 20
