3. Electrical Installation
While the sensor offers multiple options for operation, Magnetek recommends the following settings for
overhead crane collision avoidance applications to ensure optimum safety.
Figure 7: Recommended DIP Switch Settings for Overhead Crane Collision Avoidance
Applications
With the switches in the above position, the NO contact will be closed when the sensor is powered and
crane is at a safe distance from the target. Alternately, the NO contact will be open when the sensor
reaches an unsafe distance, i.e. the trip point or when the sensor loses power. With these settings, the
position of the delay dial is irrelevant.
Figure 8: Electrical Connections
Figure 9 shows how to connect the sensor to an IMPULSE®•G+/VG+ Series 4 drive utilizing a sensor for
both of the directions the crane would move down the bridge. This example stops motion in the direction
of travel when the sensors cross the detection threshold.
