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
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 A 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.
How to learn or erase the remote
Learn the remote
Press and release the learn button, the
LEARN LED
light will be on, then press the key in the remote twice
in 2 seconds, the
LEARN LED
light will flash for 4
seconds. Now the remote has been learnt successfully.
This control board can learn up to six remotes , if you
want to learn more, we recommend that you buy the external receiver
（
LM138
）
.
Erase all the remote codes
Press and hold the learn button until the
LEARN
light is off. Now all remote codes have been erased.
How to use the remote to control the operator
Key A
is used to operate the operator to work alternately (open-stop-close-stop-open).
When the Pedestrian Mode function is enabled,
Key B
is used to achieve the
Pedestrian Mode function (open the gate for the pre-setting time). When the
Pedestrian Mode function is disabled, the operator works alternately (open-stop
-close-stop-open) by pressing
Key B
.
