Pressurized Line Leak Detection
This function allows you to enter information about Pressurized Line Leak Detectors (PLLD) installed on product
pipelines in the system. You must enter data individually for each PLLD.
Line Manifolding Implications for AccuChart
For PLLD installations with line manifolded tanks, the master tank’s check valve’s relief pressure must be below the
pump’s operating pressure. AccuChart will run when there is line manifolding with PLLD line leak detection;
however, you should disable AccuChart if the results are poor. Also leaky valves will degrade AccuChart
performance. To disable AccuChart, select ‘Never’ at the Calibration Update step (In-Tank Setup, page 7-12).
PLLD Setup

Activating PLLDs
This display allows you to activate up to six PLLDs. In the active state, PLLD attempts to conduct line leak tests
whenever the dispensers are off.
To activate a PLLD, you replace the X with a number by pressing the CHANGE key. To leave a PLLD inactive,
leave an X in its position. You move between PLLDs 1 through 6 by pressing the right or left arrow key.
Press ENTER to confirm your choices (in this example you activate all six). The system displays:
Press STEP to continue.
Labeling PLLDs
This display allows you to label the line being monitored by a particular PLLD (location, fuel type, etc.).
If necessary, press TANK/ SENSOR to select the desired PLLD in the system.
