GenSet Calibration

This menu is only available in Decision-Maker
Menu—Reset Calibration with controller firmware version 3.0.25 or higher.
Display provides access to the calibration factors for metering (volts and amps). Changing the system voltage or replacing the
main logic control circuit board requires calibration adjustment. Connect a meter with a minimum accuracy of 1% to the GenSet
output leads to calibrate the voltage-sensing logic.
The user can individually calibrate the values or reset all of them. The local display Reset all calib? No or Yes. Select No to
make no changes and exit GenSet Calibration. Select Yes to reset all of the values.
When calibrating voltage, the metered value and the number being entered as the calibrated value must be within 10% of the
system operating voltage.
When calibrating current, the metered value must be at least 25% of the rated current on units smaller than 100 kW and at least
50 amps on units rated larger than 100 kW. The number being entered as the calibrated value must within 10% of the metered
value.
