Assembly of Switch Car™

 Step

SENSOR CAR AND BAYONET ADAPTER: 

The sensor car assembly is the heart of the Smart Trak™ system. It slides in the grooves of the track, and 
is locked into position by a plastic bolt and screw. The bayonet to 3/4" NPT adapter has a female 3/4" 
NPT fitting on one end where the sensor (not included) will screw in, and a bayonet fitting on the other end 
that attaches it onto the sensor car with a slight turn, with an O-ring in-between to provide tension for the 
push-and-turn connection.

DETERMINE THE PROPER WIRE LENGTH: 

Don’t make the mistake of trimming the sensor wires too short before the process is tested. If the sensors 
might need to be lowered in the future, leave sufficient slack in the wires to allow for future adjustment. 
This extra wire may be stored in the bottom of the terminal strip housing, or elsewhere above the 
compression fitting.
