Turnbuckle Shaft Jam Nut Upper Crank Arm in closed position 2 3 Lower Crank Arm in closed position See Note Pulley 01-G0674F15 Figure 13: Model BG790 Doc 01-G0674 Rev E Installation Step 6: 18 Limit Switch Adjustments Open Limit Switch Close Limit Switch Auxiliary Close Limit Switch OPEN Direction CLOSE Direction 01-G0674F16 Figure 14: Limit Switch Layout CLOSE LIMIT SWITCH The CLOSE limit switch is preset at the factory. If you rotated the pulley in section Arm and Turnbuckle Shaft Adjustments (page 16), you will need to reset the cam on the CLOSE limit switch. Then rotate the cam in the close direction so that the switch just clicks when the gate arm is in its lowest position (see Figure 14). When the cam is in the desired position, retighten the set screw. This adjustment may have to be fine tuned after turning on power and running the unit for the first time. AUXILIARY CLOSE LIMIT SWITCH The AUXILIARY CLOSE limit switch is preset at the factory. If you made an adjustment to the CLOSE cam, you will need to adjust the cam on the AUXILIARY CLOSE limit switch also. 1 Position the AUXILIARY CLOSE cam slightly ahead of the CLOSE cam. When the gate arm is on its down travel, the AUXILIARY CLOSE switch will click just before the CLOSE switch. When the cam is in the desired position, retighten the set screw. 2 OPEN LIMIT SWITCH The OPEN limit switch is preset the factory. This setting may have to be fine tuned after running the unit for the first time. 1 2 Loosen the OPEN cam and rotate in the open direction until the switch just clicks. Retighten the cam.

Vehicle Detectors Almost all types of vehicle detectors may be used in conjunction with both model BG770 and BG790. More than one detector may be connected to the gate, and may be mounted inside of the cabinet. Connect the detector(s) according to the instructions on the wiring diagrams supplied with the gate and with the detector itself. FACTORY SUPPLIED PLUG-IN DETECTORS LiftMaster P/N 71-416-7NH = 24V Please note: Previous models used 115V detectors (P/N 71-416-3NH). OPEN LOOP DETECTOR 1 2 Snap the detector onto one set of the four board mount standoffs located on the inside of the electrical cabinet. Plug the harness into the connector marked "OPEN". Connect the two loop wires to terminals P1 and P2 as shown on the wiring diagram. HOLD OPEN LOOP DETECTOR 1 2 Snap the detector onto one set of the four board mount standoffs located on the inside of the electrical cabinet. Plug the harness into the connector marked "HOLD OPEN". Connect the loop wires to terminals P3 and P4 as shown on the wiring diagram. Radio Controls All types of standard radio controls may be used in conjunction with model BG770 and BG790. If the receiver is mounted inside of the gate enclosure, a commercial coaxial antenna should be used and extended through the side of the cabinet. POWER CONNECTION All radio receivers require a power supply. If the receiver requires 24 volts AC you may power the unit from the gate control circuit. To do this, connect the radio receiver power wires to Terminals #3 and #6 on the control terminal strip. If the receiver requires 115 volts AC or other power, you will need a separate power source.
