When the appropriate detector appears on the screen, press CHANGE. Enter up to 20 alphanumeric characters
for the pipe label and press ENTER. The system confirms your entry with the message:
Press STEP to display the message:
Enter the number of the tank on which the Line Leak Detector has been installed. This number must be the same
number assigned to the tank by the system during the in-tank setup. (Refer to In-Tank Setup, Section 7.)
NOTE: If you are uncertain of the tank number, print an inventory report and review the tank number assignments.
The system automatically picks up important tank data and includes this information in alarm and status reports.
NOTE: Except for the LINE CONFIG message, you may use the TANK button at any time during the Setup
procedure to access another Line Leak Detector.
To enter the number of the tank on which the Line Leak Detector has been installed, press CHANGE and enter a
number between 1 and 8. Press ENTER. The system confirms your entry with the message:
Press STEP to continue.
Enter Dispense Mode
If necessary, press STEP until you see the message:
This step lets you choose the dispense mode of the tank(s) on which the Line Leak Detector has been installed.
The choices are:
•
STANDARD - Only one pump feeds the line.
•
MANIFOLDED: ALTERNATE
1
- The pump will run in the tank with the greatest inventory volume.
•
MANIFOLDED: SEQUENTIAL
1
-The tanks are pumped low one at a time. When the tank’s volume drops below
the entered Pump Threshold percentage, pumping will switch over immediately to the next available tank in the
line manifolded set. Pumping will continue from the current tank for another 10 seconds to avoid a disruption in
dispensing during the switch over. (see “Pump Threshold” on page 7-26).
•
MANIFOLDED: ALL PUMPS - All pumps on the line are run.
To select Standard (the system default), press STEP. To choose one of the Manifolded options, press CHANGE
until the option you want appears. Then press ENTER. The system confirms your choice with the message:
1. To prevent backfilling, the level of all tanks connected to the line will be monitored. If the level of any tank
exceeds 95% of the Max or Label Volume limit (see “Max or Label Vol” on page 7-16), the pump for that tank
will also be turned on during dispensing. The state of the pump that was already ON will not be changed.
