AUTO ACTIVE SWITCHOVER
If MANIFOLDED: ALTERNATE or MANIFOLDED: ALTERNATE-HT are selected for Pump Sense Dispense Mode,
the console can be programmed to automatically switch from the active pump to the pump in the alternate tank
when the difference between the starting tank’s volume/height exceeds the alternate tank’s volume/height by the
programmable active switchover threshold value, see below.
Press STEP to continue:
With the enable setting set to NO, auto active pump switchover will be disabled. Left in this state, when a
dispense starts, the pump in the fullest tank will turn on and run until the dispense ends.
With the enable setting set to YES, when a dispense starts, the pump in the fullest tank will turn on. As the starting
tank’s volume/height drops below that of the alternate tank by the active switchover threshold amount, the console
automatically switches to the pump in the alternate tank. Active switchover will continue as necessary until the
dispense ends.
To prevent rapid switching of the pump relays back and forth, a pump must be running for 2-minutes before
automatic pump switchover becomes enabled.
Press CHANGE to enable Active Switchover and ENTER to confirm. If you selected Manifolded: Alternate you will
see this message:
If you selected Manifolded: Alternate-Ht you will see this message:
For MANIFOLDED:ALTERNATE, the selectable threshold range is 10 to 999 gallons (37 to 3781 liters) - 200
gallons (757 liters) is the default. For MANIFOLDED:ALTERNATE-HT, the selectable threshold range is 1 to 99
inches (25.4 to 2514 mm) - 2 inches (50.8 mm) is the default. Press CHANGE to change the threshold value and
ENTER to confirm.
