aXis CONTROLLER HOME STANDBY GENERATOR
INSTALLATION

This failure could be the result of an excessive load or high
ambient temperatures. Should this fault occur do the following;
Open the enclosure doors to increase air flow throughout the unit
Check oil level add oil if required
Inspect the interior and exterior of the enclosure for debris, leaves,
etc., and remove them to increase air flow around and inside the
unit.
Once the engine temperature falls into the normal operating range,
generally 30 minutes, follow the reset procedures in the manuals
specific to your model to clear and correct fault.
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
reset procedures contained in the manuals specific to your model
to clear and correct. 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
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 fault LED on
the back of the HSB enclosure will be activated and lit.
Appliances connected to the generator circuit could be damaged
from high generator output if the engine operates above the
factory preset limits. If this failure occurs, contact Champion or
your Authorized Champion Dealer. The RED icon will remain lit
until the failure has been corrected, the HSB will not attempt to
transfer or run.
Line Over Voltage
The RED icon will be lite if the HSB generator output power
exceeds preset limits of 257 VAC.
When this fault occurs, the HSB will light the RED icon, shut down
and re-start will be disabled. The exterior fault LED on the back of
the HSB enclosure will be activated and lit. Check and adjust AVR.
Set Voltage to 240 VAC.
Line Under Voltage
The RED icon will be lit if the HSB Generator output power is
below preset limits of 190 VAC.
When this fault occurs, the HSB will light the RED icon, shut down
and re-start will be disabled. The exterior fault LED on the back of
the HSB enclosure will be activated and lit. Check and adjust AVR.
Set Voltage to 240 VAC.
Low Battery
The RED icon will be lit if the battery voltage falls below 21.0
volts for at least 5 seconds while the engine is running. If the
battery voltage rises above 22 volts, the icon will turn off. Battery
voltage is NOT monitored when the engine is cranking, just when
the engine is running. If the RED icon comes on it will not shut
the HSB off, it will remain lit until the battery condition meets the
required output.
