Generator Meters and Gauges
(1) Voltmeter
The voltmeter displays the three-phase output
voltage (voltage between L1-L3). Check that
240 V is displayed during operation. Output
voltage for single-phase three-wire (voltage
between U-W) is the same voltage as the
three-phase output voltage (voltage between
L1-L3). Accordingly, use the voltage meter
displayed value as a reference.
* Check that 480 V is displayed during operation if using at the three-phase 480 V setting.
The voltage of single-phase three-wire output of "U-W Voltage" is a value that is one half of
the displayed voltage meter value.
(2) Ammeter
Displays the output current (phase current) of the generator. Turn the ammeter selector
switch to "L1+U" to display the output current of the three-phase L1 phase and single-phase
U phase. Turn the switch to "L3+W" to display the output current of the three-phase L3 phase
and single-phase W phase. "L2" displays the output current of three-phase output terminal
L2.
< Note >
 If measuring the output current for a single-phase three-wire type, turn the ammeter selector
switch to "L1+U" or "L3+W". The voltage cannot be accurately measured if set to "L2".
(3) Frequency Meter
Displays the frequency of the power source. Check that 60 Hz is displayed during operation.
Indicators
(1) Pre-heating Indicator
The pre-heating indicator illuminates when the starter switch is
at PREHEAT. The pre-heating indicator turns off when
pre-heating is completed to indicate that it is possible to start
the generator.
< Note >
 Pre-heating time depends on the coolant temperature, and
should be completed in approximately 0.5 to 8 sec.
(2) Pilot Lamp
This illuminates when the engine is operating to indicate that power is being generated.
