How to install and operate a 3-compartment TD100 system with a FINCH II-6W display and optional onboard loading pump control for spill prevention

The information below describes how to install and operate a 3-compartment TD100 system with a FINCH II-6W display and optional onboard loading pump control for spill prevention. 

System Description

•  3-compartment B-Train
• Dual-compartment lead trailer
• Single-compartment rear or pup trailer
• Wiring includes an optional onboard loading pump control

This configuration allows operation with the two trailers or the lead trailer only. 

The pup-mounted TD100 transmitter is connected to the FINCH II-6W Display by a pair of J560 sockets and a 7-way cable. Titan does not supply these items.

Operating with only the Lead Unit (disconnecting the Pup)

Operation with only the lead unit is accomplished by inserting a J560 Dummy Plug into the J560 socket on the lead unit. When operating with the pup, the Dummy Plug is removed and the 7-way cable connects the two units for normal 3-compartment operation.

When operating without the rear unit and the Dummy Plug is installed, the Compartment 3 volume is shown the same as Compartment 2. The lead unit will operate as a normal 2-compartment system with compartment 3 volume following compartment 2.

Dummy Plug Construction

The Dummy Plug is constructed with common heavy truck and trailer electrical components. The recommended list of parts is below. Titan does not supply these items.

• QTY 1, Phillips PermaPlug, Part Number 16-730 or equivalent, for the J560 Dummy Plug
• Short length of #14 AWG insulated wire
• QTY 1, Rubber stopper or plug with a diameter of a typical 7-way cable (1/2”)
  
  

1. Seal the PermaPlug’s cable compression fitting with a suitable rubber stopper or plug.
2. Strip each end of the insulated wire.
3. Connect the wire to pins 4 and 5 of the PermaPlug.
4. Assemble the PermaPlug.
5. Attach a label on the plug stating “For TD100 System Use Only”.
