Irreversible barriers (LBA4/6/7)
1
st
step: Adjusting the sensors
For irreversible barriers, the sensors determine the barrier's open or closed position.
This is a drawing of a barrier in normal direction, in the case of a barrier in the reverse direction, the sensor positions
are reversed.
➢
Opening sensor setting
1-
Set the sensor so that it is activated (the sensor’s light must be on) at approximately 10°
before the vertical position (90°)
2-
The barrier must stop in vertical position
3-
When you have reached the ideal setting, tighten the nut on the detection cam side using a 17
mm spanner
➢
Closing sensor setting
1-
Set the sensor so that it is
activated (the sensor’s light must be on) at approximately 10°
before the horizontal position (0°)
2-
The barrier must stop in horizontal position
3-
When you have reached the ideal setting, tighten the nut using a 17 mm spanner
