Converter Power Calibration
- The CONVERTER POWER calibration works in a
fashion similar to the SHORE POWER calibration described above. Converter voltages
are measured and entered phase-to-neutral. Press and hold the CONVERTER POWER
(4)
button for 7 seconds, or until the converter power calibration display appears. Move
the reference meter probes from the input to the output terminal blocks. Then use the
CONVERTER POWER
(4)
button to move the cursor to the parameter to be calibrated.
The F1
(13)
button will increment the displayed value, the F2
(13)
button will decrement
it. Press the SYSTEM STATUS
(5)
button to exit the calibration function. Select the
CONVERTER POWER
(4)
display to verify the calibration correction factors have been
stored.
5)
Generator Power Calibration
- Use an external reference voltmeter to measure the
generator voltage at the generator terminals located on TB12-1, 2, and 3. Generator
voltage is measured and entered phase-to neutral. To enter the meter calibration screen,
press and hold the GENERATOR POWER
(3)
button down for 7 seconds, or until the
calibration display appears, then release the button. Use the GENERATOR POWER
(3)
button to move the cursor to the voltage phase to be calibrated. Calibrate the selected
parameter by pressing the F1
(13)
button to increment and the F2
(13)
button to
decrement the displayed value. When all displayed values equal the values measured by
the reference meter, pressing the SYSTEM STATUS
(5)
will store the new calibration
values and return the display to the System Status display. Press the GENERATOR
POWER
(3)
button to verify proper shore power meter calibration.
NOTE : Calibration of the Generator Metering Display is required only when the
Seamless Transfer option is installed
Calibration is now complete, the converter may be returned to service.
