Line Leak Testing
Overview
Line Leak Detection is available only if the option for Line
Testing is enabled. This option can be ordered when
purchasing the console or after the initial purchase by
using the part number TS-ELLD. An AC Input, 4-20mA, and
either a relay module or the use of TPI will also be required
to perform Line Testing.
Line Leak Testing for all T5 series FMS consoles use
software rules to automatically run tests. Tests may be
started manually from the console or remotely using TSA.
AutoLearn software monitors line conditions by conducting
a multitude of electronic line pressure sensing tests.
Line Leak Detection is required in many areas to monitor
for potentially hazardous environmental contamination. In
the event of a leak, the system may provide positive pump
shutdown (to prevent further contamination) and display an
indicator light and on-screen description of the condition as
console alarm notifications. A high intensity remote alarm
may also be used if applicable. After installation, the user
of the system must monitor the system to ensure that any
leak alarm and pump shutdown (indicating a line leak) is
dealt with promptly.
The LS500 LLD system can detect a leak from the check
valve in the pump to the solenoid valve at the dispenser —
assuming no other normally closed valve is in the pipeline
system. This system does not detect leaks from the fuel
storage tank. The LS500 should be used in applications
where site conditions are in accordance with Third Party
testing (as listed in the NWGLDE section of this chapter).
Terms

Line Leak Testing Requirements
To perform Line Leak testing, the Line Leak software
must be enabled. To verify that the Line Leak software is
enabled:
1. Starting at the Home Screen, open the Quick Jump
Menu.
2. Select Utilities from the QJM then select System.
3. Press the Software Options Button.
4. Under Software Options, a Line Testing row will appear.
A “Yes” in the Enabled column indicates that the
software has been purchased and is enabled.
