Roll Door Sensor Installation Overview
The roll door sensor kit contains the rear door switch with attached 3-foot cable assembly, a
magnet, and an 85-foot door sensor cable assembly. (The replacement roll door sensor kit
comes without the 85-foot cable assembly.)
The door sensor cable assembly is typically routed externally, under the trailer up to the
TT210 system mount assembly (along the same route as the factory wiring and/or brake
lines).
At the TT210 system mount assembly, the two roll door sensor cable wires are butt spliced to
the yellow (DOOR-) and orange (DOOR+) wires coming from the TT210 system power/
accessory cable assembly.
Roll Door Sensor Validation
A simple opened/closed magnetic switch detects when the state of a trailer door changes.
The interval is set up per the customer’s request and state change reports are sent to the
customer, as shown in the following illustration.
