2. Potentiometers
The potentiometer A is to adjust the
OPEN
stall force of the gate operator. The Potentiometer B is used to
adjust the
CLOSE
stall force of the gate operator.
Turn the potentiometer clockwise to increase the stall force.
Turn the potentiometer counter-clockwise to decrease the stall force.
Test the reversing sensitivity
For the sake of safety, it is very important to test the reversing sensitivity as soon as the control board set is
finished.
The reversing sensitivity adjustment is inverse correlation with stall force adjustment in
potentiometer A
and potentiometer B
. In other word, the stall force level is higher; the reversing sensitivity level is lower.
Put an immobile object along the gate path, and then operate the gate to strike it during the open and close
cycles. The gate must reverse as soon as object is struck with it. If the gate doesn’t reverse, please increase
the reversing sensitivity by turning the potentiometer in counter-clockwise direction. (Turning the stall force
potentiometer toward to MIN position to increase the reversing sensitivity)
Note 1: If the sensitivity setting is too higher, the gate will stop or reverses very easy by itself while
there is little obstruction or resistance such as strong wind or heavy snow sometimes.
Note 2: Always check the gate reversing function every each time of control board set or restart after
power off.
