For less downward travel, loosen the wing nut on the to open it, you may need to adjust the open direction current LSC-1 (down) limit cam and rotate the cam slightly in sensor one turn higher. Refer to Page 9 for details of current the “A” direction. sensing adjustment. 3. For more upward travel, loosen the wing nut on the LSO-1 (up) limit cam and rotate the cam slightly in the “A” direction. 4. For less upward travel, loosen the wing nut on the LSO-1 (up) limit cam and rotate the cam slightly in the “B” direction. ELECTRICAL CONNECTION AND ADJUSTMENTS Power supply must be of correct voltage and phase. Always follow national and local electrical codes when wiring and use a qualifi ed electrician. Always disconnect power from operator before servicing. Keep clear of gate arm during operation. All LINEAR gate operators are supplied with a power disconnect switch to turn on and off the power supply available to the operator. Incoming power should be brought into the operator and connected to the labeled pigtails in the disconnect box, following wiring specifications on Page 4. A wiring connections print can be found on the inside cover of the operator. Proper thermal protection is supplied with the operator. The motor contains a thermal overload protector to protect from overheating the motor due to overload or high-frequency operation. This overload will reset automatically after the motor cools down. -8 MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE CONTROL BOARD ADJUSTMENTS R2 BRAKE 2A FUSE TERMINAL STRIP #2 DIAGNOSTIC RESISTOR CONNECTOR L.E.D.s NOTE: DO NOT FORCE 270-DEGREE POTENTIOMETERS BEYOND THEIR NORMAL RANGE OF MOTION OR DAMAGE MAY RESULT! Auto Close Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to close automatically, from the fully open position, provided no open, reversing or obstruction signals are present. The timer is adjustable from 0 to 124 seconds. This feature is turned off or on using dip switch #1. Maximum Run Timer Adjustment: This 270-degree adjustable potentiometer should be left in the fully clockwise position on all barrier gate operators. Open Direction Current Sense Adjustment: This multi-turn potentiometer is used to calibrate the built-in current sensing feature for detection of obstructions while running in the open direction. Close Direction Current Sense Adjustment: This multi-turn potentiometer is used to calibrate the built in current sensing feature for detection of obstructions while running in the closed direction. Master/Slave Connection Block: This terminal block is used in conjunction with two operators to configure two gates to open and close together. Dip Switches: #1 This switch turns the auto close timer off/on. #2 This switch controls the behavior of the open/reset function in barrier gates only. When the switch is turned ON, a momentary open/ reset pulse will cause the arm to raise and stay raised until a reset or another open/reset signal occures. In the ON position, this switch also disables the counting function of Dip Switch #4. When the switch is turned OFF, the arm will lower as the open/reset signal is no longer present. #3 This switch is used in conjunction with single-button controls and radio receivers. In the ON position, successive inputs will cause signals in the order of OPEN-STOP-CLOSE-STOP. In the OFF position, inputs will cause an OPEN signal unless the gate is fully open, in which case it will signal CLOSE. #4 In the OFF position, for every open signal the barrier gate receives, there must be a reset signal before the arm will come down. In the ON position, this feature is disabled. #5 In the OFF position, if two vehicles are close together and the second vehicle triggers the reset loop as the arm is coming down, the arm will stop until the second car is clear of the loop, then continue down. In the On position, the arm will continue down even when a second car triggers the reset loop. If the application requires that only a single vehicle pass through at a time, then this featurte should be ON. In all other cases the feature should be left OFF, as the arm will come down onto a tailgating vehicle. #6 In the ON position, this switch will disable the inherent DC brake in DC operators only. In addition, the R2 brake resistor on the DC motor board must be cut from the board (refer to the picture above). In the OFF position, the DC brake will function. #7 Not used at this time. #8 This switch is used to set ...
