8 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
SHORE POWER connections checked by a
qualified electrician (refer to Figure 4).
Upon initial power-up, no fan activity is heard
or otherwise detected.

Have the fan fuses located to the right of the
CONVERTER POWER connections checked by a
qualified electrician (refer to Figure 4).
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.
