default setting).
DIP Switch #5: Left/Right open
ON
– Left open (factory default setting).
OFF

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.
E.g. Auto close time of the gate operator is 30+60=90 seconds.
