Terminal Overfill with FINCH III Feature

Terminal Overfill Feature Overview

The Titan TrueFill system uses the FINCH III display as the onboard monitor for terminal overfill protection. When Terminal Overfill, also referred to as Rack Control, is enabled, the FINCH III connects to the truck’s API rack loading socket and controls whether the loading rack is permitted to load the truck.

The FINCH III is designed for fail-safe rack loading operation. A permissive signal is only provided when the FINCH III system is powered on and all required system checks have passed. If the FINCH III display or connected Titan hardware loses power, the permissive signal is removed and loading will not be allowed to continue.

Before allowing loading at the rack, the FINCH III confirms the following:

• No HH or SPILL rack shutdown condition is active on any compartment.
• No unexpected level movement is detected, such as a transmitter reading jumping from mid-tank directly to 2Lo or SPILL.
• No transmitter or FINCH III system error is active.
• The FINCH III is not connected to Titan Install or in update mode. (Showing RCONN or in Update mode)
• All required compartments are confirmed and all transmitters are properly assigned.

If any of these conditions are not met, the FINCH III changes the rack status to non-permissive and loading is stopped until the condition is resolved.
