See Figure 14. 2 Retighten the cam. Doc 01-G0674 Rev E Optional Accessories 19 Optional Accessories CAUTION Turn off power before working inside gate enclosure. 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 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". 2 Connect the two loop wires to terminals P1 and P2 as shown on the wiring diagram. HOLD OPEN LOOP DETECTOR 1 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". 2 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. A standard residential door radio receiver has a three wire connection marked 1, 2, 3. If you have this type, you may connect to operator terminals R3, R1, and R6. The transmitter button will open the gate if it is fully closed. CONTROL If you have a standard residential 3 wire receiver and made the power connection described on page 19, you are finished with the radio connections. If you want to use a radio control (such as a single button), you must order an optional kit (P/N 90-PGR). Doc 01-G0674 Rev E Installation 20 Card Readers, Keypads, or other Almost all types of access control devices may be connected to models BG770 and BG790. More than one device may be connected in parallel. All devices connected according to the instructions below will open the gate and reverse the gate if it is closing. MOUNTING LOCATION Mount or install the access control device within sight of the gate and according to the instructions supplied with the device. Some devices require their own power supply. Do not use the 24 volt power in the gate to supply other devices. Use either direct line voltage (115V or 230V) or other external power source as required by the particular device. NOTE: Most access control devices have an isolated, normally open output contact to connect to the gate. If yours does not, or if you are unsure of or unfamiliar with these terms, consult the supplier of the device or a qualified gate installer. CONTROL CONNECTION TURN OFF POWER and connect the two output terminals (or wires) of the access control device to the terminals #1 and #3 on the control wiring terminal strip. Use a wiring method that will provide permanent, durable, and weatherproof connection between the gate and the access device. Doc 01-G0674 Rev E Operating Instructions 21 Operating Instructions Electrical Operation The BG770 and BG790 barrier gate operators are designed to provide years of trouble-free operation. The gate may be operated by means of the two button control station, or by other means if provided. ON/OFF POWER SWITCH The gate is provided with an ON/OFF power switch. To shut power off, remove the access cover and move the toggle switch on the right side of the main electrical cabinet to the "OFF" position. OVERLOAD PROTECTION The motor is protected by either a manual reset (Single Phase unit) or automatic reset (3 phase unit) thermal overload protector. The overload protector will trip when the motor temperature is too hot. DO NOT ATTEMPT TO BYPASS THIS UNIT If the overload trips, the gate could start by itself when the overload is reset (either manual or automatic). Exercise caution when resetting the overload. On one phase units, the reset button is located on the cover of the electrical cabinet. If after resetting, the overload continues to trip, consult a qualified service company. Manual Operation Keep hands clear of moving parts. The motor will start when AUTO/MANUAL Switch is flipped to the .MANUAL. position. ACCESS CONTROL .EMERGENCY. BYPASS To open the gate in an emergency, remove the keyed access cover and open the electrical cabinet. Flip the AUTO/MANUAL switch to the "MANUAL" position. The gate arm will remain in the up position, and no other control devic...
