IMPORTANT: Voltage calibration
Experience has shown that some inverter/charger voltage measurement circuits are inaccurate.
Compare the voltage values displayed by the inverter/charger with that of a calibrated voltmeter.
If the actual voltage differs by more than 100mV from that measured by the inverter/charger, apply this
difference to the highlighted values above (i.e. if actual voltage = 56V while inverter voltage = 56.5V,
the voltage difference = 0.5V should be subtracted from each of the set values above).

TROUBLESHOOTING
Every BlueNova® product contains integrated circuitry as a safety measure against possible damage
from electrical malfunction. Under such conditions, the red Error LED on the Control Panel will flash to
indicate a specific error.
Before troubleshooting any errors, first check the following:
•
Ensure that units are stacked in the correct order. Refer to Illustration 2A.
•
Ensure that the signal cable and busbars are tightly connected.
•
Ensure that fuses are fitted correctly and in working order (i.e. not
blown
).
The following table explains each error LED flash sequence, and the procedures to follow:
Flash Seq. Error
Procedure
1 x flash
Fuse
1.
Check fuses and replace with the same type if necessary.
2 x flashes
Comm Cable
1.
Ensure all connections are securely tightened.
3 x flashes
Over-charge
1.
Check settings on inverter / charger. Refer to C. Installation
4 x flashes Over-discharge
1.
Check settings on inverter / charger. Refer to C. Installation
2.
Ensure that the charger will switch on.
3.
Keep Reset button depressed until battery switches on.
No flashes
Comm Cable
1.
Check battery output & inverter input connections.
2.
Ensure Comm cable connections are securely tightened.
IMPORTANT: Deep Discharge Lockout (DDL) Mode
BlueNova® batteries have been designed with protective countermeasures against malfunction and
abuse. Whenever V
low cut-off
is reached (refer to C. Installation), the battery will isolate itself
automatically from the inverter/charger and load. The battery will enter
Sleep Mode
at this point, and
may be switched on again by following the procedure detailed above for an over-discharged battery.
Should a battery in Sleep Mode not be recharged within 8 weeks of switch-off date, the small load
resulting from the standby circuitry will drain the battery sufficiently to result in the battery entering
DDL Mode
. Recovery from DDL Mode is a lengthy process, and would involve a product recall to
BlueNova® facilities as well as a service fee. See F. Battery Storage Guidelines for more information.
