6.1 POWER TURN-ON PROCEDURE, cont.
6.1.2 Systems Equipped With The Seamless Transfer Option
With the converter in the Standby State (as left at the end of Section 6.1), press the GENERATOR
POWER (3) display button. The generator voltage and form will now be displayed. If two
generators are installed, select Generator #1 or Generator #2 by pressing the F1 (13) or F2 (13)
button after selecting the GENERATOR metering screen.
NOTE: Unlike the converter and shore power displays, generator load current is not measured by
the system, and as such no data can be displayed for current, kW, or kVA.
To determine generator status to the electrical system, observe the
SHIP’S POWER
button group.
Two LEDs are included in this group, one next to the
SHIP’S POWER - CONVERTER
(9) button,
the other next to the
SHIP’S POWER - GENERATOR
(12) button. The LED (9A) next to the
CONVERTER button will be lit when the converter is on and supplying power to the ship’s
distribution grid. The LED (12A) next to the GENERATOR button will be lit when the generator is
supplying power. The SHIP’S POWER LEDs should never be lit at the same time: only one source
of energy should be connected to the ship’s distribution system at any point in time. If the
GENERATOR LED is lit, but the GENERATOR metering display indicates no power present, then
the GENERATOR is connected to the distribution grid through its circuit breaker, but the generator
is off.
NEVER ASSUME A CIRCUIT IS INACTIVE (WITHOUT VOLTAGE ) BY RELYING UPON
THE SHORE POWER CONVERTER’S METERING SYSTEM. DO NOT ACCESS THE
ELECTRICAL SYSTEM WITHOUT PROPERLY VERIFYING THE SAFETY OF THE
SITUATION USING ALTERNATE MEANS.
