‘Fault’ Screens :
FREQ. FAULT DETECTED:
This fault is displayed when the
controller detects the high voltage
feedback frequency is either below or
above the Min and Max frequency
settings selected.
The fault indicator only appears after
a time period to allow for minor
fluctuations in frequency that may
occur
during ‘load-no-load-load’
transitions
If this fault is triggered, the HGC-2
PWM output will be set to zero output
( i.e. minimum generator speed ) until
the HGC-2 is first disabled and re-
enabled or the supply power to the
unit is cycled.
To correct this issue, the operator
should first isolate and fully stop
the generator and check the high voltage feedback connections to and the HGC-2 controller for correct and firm connection. If
these are secure, the settings for the HGC-2 may need to be adjusted
– please contact HCT for assistance.
SHORT CIRCUIT FAULT DETECTED:
This fault is displayed when the
controller detects that the proportional
coil or wires being attached to the PWM
output have become short circuit or
have failed internally to a short-circuit
condition. Other causes of this fault
detection may be shorted wires to the
valve or within the generator set
enclosure.
If this fault is triggered, the HGC-2 PWM
output will be set to zero output ( i.e.
minimum generator speed ) until the
HGC-2 is first disabled and re-enabled
or the supply power to the unit is cycled
and no further short circuit is detected.
To correct this issue, the operator
should first isolate and fully stop the
generator and check all connections
to and from the HGC-2 controller for correct and firm connection
