LIMIT SWITCH ADJUSTMENTS
CLOSE LIMIT SWITCH The CLOSE limit switch is preset at the factory. If you rotated the pulley in section Arm and Turnbuckle Shaft Adjustments, you will need to reset the cam on the CLOSE limit switch. Then rotate the cam in the close direction so that the switch is activated when the gate arm is in its lowest position (Figure 12). 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. When the gate arm is on its down travel, the AUXILIARY CLOSE switch will activate just before the CLOSE switch. This setting may have to be fine tuned after running the unit for the first time. Loosen the OPEN cam and rotate in the open direction until the switch is activated (Figure 12). Figure 12
