GATE SENSITIVITY ADJUSTMENTS
The gate operator monitors both average and peak motor current. When the gate encounters an
obstruction, the gate operator senses the change in motor current and stops or reverses the gate.
Three sensitivity adjustments are factory-set for most installations:
•
Right gate motion (R78)
•
Left gate motion (R81)
•
Inrush current (R119)
NOTES: The Overload adjustment (R71) is factory set only. Do not adjust.
If your installation requires different sensitivity adjustments, use the following procedures:
♦ For Typical Installation, set switch S2 to "Open to Left" position and use the "Typical
Installation" adjustment procedures below. For Restricted Installation, set S2 to "Open to
Right" position and use the "Restricted Installation" adjustment procedures.
♦ The minimum sensitivity is full clockwise and maximum sensitivity is full counter clockwise.
These adjustments must be made while the gate is in motion.
♦ Before starting the adjustments, verify that the Left and Right reverse pots are set fully
clockwise, and the Inrush pot is set to the 9 o'clock position (see Figure 10).
IMPORTANT: Current flow varies with temperature. Do not tune the sensitivity measurements too
♦ Make all adjustments in the order listed.
1. TYPICAL INSTALLATION ADJUSTMENTS
"Left Reverse" Adjustment (R81)
1. Initiate opening the gate.
2. Wait 1 to 2 seconds, then lightly "tug" against the edge of the gate to simulate an obstacle.
3. If the gate does not stop, reclose the gate and adjust the pot slightly counterclockwise.
4. Repeat steps 1-3 until the gate stops when tugged and has the desired sensitivity.
"Right Reverse" Adjustment (R78)
1. Open the gate fully, then initiate closing the gate.
2. Wait 1 to 2 seconds, then lightly "bump" the leading edge of the gate to simulate an obstacle.
3. If gate does not stop or back up, reopen the gate and adjust the pot slightly counterclockwise.
4. Repeat steps 1-3 until gate stops or backs up when bumped and has the desired sensitivity.
