Selecting a Dispense Mode
NOTE: This option will only appear if a tank has been selected for the PLLD.
If necessary, press STEP until you see the message:
In this step you select the dispense mode of the tank. The choices are:
•
STANDARD - Only one pump feeds the line.
•
MANIFOLDED: ALTERNATE
1,2
- When a dispense starts, the pump in the tank with the greatest inventory
volume will run until the dispense ends. See Auto Active Switchover below for optional selections with this
dispense mode.
•
MANIFOLDED: SEQUENTIAL
1,2
- 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.
•
MANIFOLDED: ALTERNATE-HT
1,2
- When a dispense starts, the pump in the tank with the greatest fuel height
will run until the dispense ends. See Auto Active Switchover below for optional selections with this dispense
mode.
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.
2. At locations with manifolded fuel lines that have a mechanical line leak detector installed for each pump, the TLS
Console must be programmed for either Manifolded: Alternate, Manifolded: Alternate-HT or Manifolded:
Sequential. Doing so ensures that each line meets the 3 GPH requirement.
