Blue lines under tanks - Possible Issue: On
initial 12V system power up, the black
and gray tanks read full with a blue line
under them and the fresh tank reads
empty with a blue line under it.
Possible cause: On initial power up, if there is no water in the tank, the system may have
difficulty detecting the no water condition. As a result, it will display a blue line under
the tank reading for the appropriate tank and indicate the following:
• Fresh Tank – Shown with a blue line under the tank reading and the tank graphic
as being empty. Because the system is not detecting the empty fresh tank
correctly, it does not have valid data to display. As a precaution, it will display
the fresh tank graphic as empty as this is the least favorable condition for the
tank.
• Gray Tank – Shown with a blue line under the tank reading and the tank graphic
as being full. Because the system is not detecting the empty gray tank correctly,
it does not have valid data to display. As a precaution, it will display the gray
tank graphic as full as this is the least favorable condition for the tank.
• Black Tank – Shown with a blue line under the tank reading and the tank graphic
as being full. Because the system is not detecting the empty black tank correctly,
it does not have valid data to display. As a precaution, it will display the black
tank graphic as full as this is the least favorable condition for the tank.
Solution: Add at least 3 inches of water to the tank to allow the sensor to properly
initialize. Once there is water covering the sensor, it should start to report correct
readings and display the tank levels correctly.
Fluid Tank Readings (TruTank):
• Displays in 5 percent increments.
• Below 10% will read “Empty” and the
tank level will show Empty.
• 90% and above will read “FULL.” and
the tank shows accurate level.
