The default position that the “sense” dial is set to is the maximum distance. It is recommended to set the
trip point distance slightly greater than required, as time is needed to stop a moving crane; refer to Table
2 and Table 3 to help set up this distance. Once the required distance is reached, angle the sensor
outside of the 30° mark. Gradually angle the sensor into the perpendicular position of the crane until the
relay trips and the yellow indicator is illuminated. When finished, tightly close the cover to prevent dust
from getting inside the sensor.
