WARNING!
RISK OF ELECTROCUTION
DO NOT BEGIN TO SET THE FOLLOWING
ADJUSTMENTS UNTIL THE POWER IS TURNED
OFF AT THE HDSWG 1000 CONTROL BOX
With the cover removed from the HDSWG 1000 MECHANICAL UNIT, and the arm connected to the gate as well as to the HDSWG 1000 Operator, position the gate at its fully closed position. Indentify the lower Limit Switch. Loosen the clamping nut on the Limit Switch Cam for the lower Limit Switch. Rotate the cam on the output shaft until it engages the Limit Switch and an audible “click” is heard. Repeat this several times until you are confident that the position of the cam is such that the Limit Switch is just closed. Carefully tighten the nut on the Limit Switch Cam. Snug the set screw on the cam against the output shaft to protect the cam from accidental movement. Open the gate to its fully open position. Repeat this procedure for the upper Limit Switch and Cam. (See Figure 18.)
SETTING THE LIMIT SWITCHES
LEFT-HANDED OPERATION
For a LEFT HAND installation, the cam positions will be reversed. The Upper Limit Switch will be the close Limit Switch and the Lower Limit Switch will be the Open Limit Switch.
D:STARTING THE OPERATOR 
PRESETTING THE MOTOR OVERLOAD SENSITIVITY
The HDSWG 1000 is shipped from the Factory with the overload setting at its most sensitive setting. During the initial check out phase, it will be necessary to adjust the sensitivity to prevent inherent overloads from gate friction and other gate anomalies. See Figure 19. Adjust the "OVERLOAD" potentiometer approximately 1/4 turn clockwise. Note! Turning the potentiometer clockwise decreases sensitivity. Turning the potentiometer counterclockwise increases sensitivity.
WARNING: THE OVERLOAD POTENTIOMETER MUST BE SET MORE PRECISELY PRIOR TO COMPLETING THE HDSWG 1000 INSTALLATION. (See, FINAL SETTING OF THE MOTOR OVERLOAD SENSITIVITY)
SETTING THE SWITCH SELECTABLE OPTIONS
The switch selectable options are located on the Logic board. The board must be removed before the switch can be set. (BE SURE THAT THE POWER IS OFF BEFORE REMOVING THE LOGIC BOARD. The boards are keyed with a slot to prevent accidental incorrect insertion.)

The mode of operation for the HDSWG 1000 overload condition is set at the factory
The HDSWG 1000 will stop when OPENING and will stop when CLOSING, when an overload is detected by the HDSWG 1000 overload function.
