TROUBLE-SHOOTING AND DIAGNOSTICS
8.1
COMMON PROBLEMS
When encountering difficulty in achieving successful operation of the converter, there are some
problems which are easily identified and solved. The following list is not intended to be
exhaustive.
SYMPTOM
POSSIBLE CAUSE/SUGGESTED ACTION
Upon initial power-up, the converter does
not behave in accordance with the Section
6.1 description (no display, LEDs, or fans).
Ensure dock power is available. Check
pedestal and shore cord circuit breakers.
Have input power to the converter checked
by a qualified electrician.
Have the power supply fuses located above
the Input/Output connection panel checked by
a qualified electrician (refer to Figure 6).
Upon initial power-up, no fan activity is
heard or otherwise detected.
Have the fan power supply checked by a
qualified electrician.
The converter powers-up in accordance
with the Section 6.1 description, but does
not accept a SHORE POWER ON button
press.
Review SHORE POWER metering at the
converter for a three phase input between
170-520VAC.
The
converter
does
not
accept
a
CONVERTER POWER ON button press.
Review CONVERTER POWER metering at
the converter for the correct and expected
output voltages.
The converter does not accept a SHIP’S
POWER CONVERTER or SHIP’S
POWER GENERATOR button press (if
the Seamless Transfer Option is present).
Ensure that no active and un-cleared
FAILURE or WARNING messages are
present (press F1 and F2 simultaneously to
clear).
The converter trips to a SHORE POWER
OFF state unexpectedly and reports the
message “INPUT_OVERLOAD”
Review Section 7.7. Clear the kW-HOUR
screen before placing the converter on-line,
and review the maximum kW entry after a trip.
