TROUBLESHOOTING
Tank level readings change when electronics are turned on.
Make sure that the negative feeds to the tank sensors are connected as
close to the battery as possible.
When using ultrasonic sensors, high level tank alarm sounds when
power is turned off.
Ultrasonic sensors require power to operate correctly and will show a full
tank when not powered.
State of Charge (SOC) stays at 100% even when the batteries are
being discharged.
Check to make sure that when the batteries are being discharged the DC
current is negative. If it is positive, reverse shunt sense wires.
Unexpected voltage readings are shown on meter.
Make sure that all of the battery grounds are connected to each other.
The VSM uses one common ground reference.
AC current shows greater than zero but the power reading is zero or
a negative value.
Reverse the AC current transformer leads. Follow WARNING on page 3
to avoid possibly lethal shock.
A calibration error screen keeps appearing.
Contact Blue Sea Systems Technical Support for repair or replacement.
