Low Oil Pressure Shutdown
The RED icon will be lit when the engine oil pressure drops below
a safe operating level. When this fault is detected, the HSB will
shut down and re-start will be disabled. RED icon on the controller
module and exterior LED will be lit.
Check the oil level. The oil level should be at the FULL mark, if
necessary, add oil. DO NOT overfill. Inspect the unit for a possible
oil leak, if a leak is discovered, contact Champion or your nearest
Authorized Champion Dealer. Follow the FAULT CODE RESET
instructions to clear the fault after service.
High Engine Temperature
The RED icon will be lit if the engine operating temperature
exceeds the factory preset limits. If excessive operating
temperature is detected, the HSB will shut down and re-start will
be disabled. The RED icon on the aXis Controller
enclosure LED will be lit.
This failure could be the result of an excessive load or high
ambient temperatures. Should this fault occur do the following;
1. Open the enclosure doors to increase air flow throughout the
unit
2. Check oil level add oil if required
3. Inspect the interior and exterior of the enclosure for debris,
leaves, etc., and remove them to increase air flow around and
inside the unit.

4. Once the engine temperature falls into the normal operating
5. Close the enclosure doors and the unit is ready to run.
Over crank
The RED icon will be lit if the engine does not start after 5
attempts. This prevents the HSB from damaging itself or other
related components. When the fault is detected, the HSB will shut
down and re-start will be disabled. RED icon on the controller
module and exterior LED will be lit.
This failure could be the result of insufficient fuel supply. Check
the in-line fuel shut off valves and make sure they are in the ON/
OPEN position. Position them in the correct position, follow the
FAULT CODE RESET instructions to clear the fault after service.
If they are in the correct position and the HSB shows a fault light
again, it's recommended to perform a Manometer pressure check
by an Authorized Champion Dealer or installer. This will make sure
the correct amount of fuel is being delivered to the HSB when it
starts.
Insufficient battery output could result in poor cranking cycles,
not permitting the engine starter to reach optimum starting RPM
to start the engine. This can be verified by checking the Battery
Charger icon, NO CHARGE. If this occurs, the individual battery
voltages must be checked to determine if the batteries are
properly charged or if they have failed. It is extremely important
to follow all cautions and warning per the battery manufacturer
concerning installation, service, maintenance and replacement
procedures.
Hz Over speed/Under speed
and exterior
®
The RED icon will be lit if the engine was operating above or below
its preset speed limits. These limits are factory set to protect the
HSB and the circuits connected to the generator output circuits.
When this fault occurs, the HSB will shut down, light the RED icon,
shut down and re-start will be disabled. The exterior warning LED
on the back of the HSB enclosure will be activated and lit.
