PROCEDURES
If the display board is replaced, the display sensor cal-
ibration and a voltage calibration must be performed
for optimum performance. If the calibration is not
done the voltage may be accurate only to within 3
volts. If the sensor calibration is not done, the display
board may have some problems sensing the correct
overlay on power up.
WARNING
The display is shipped with the water cooler disabled.
If an internal water cooler is being used with the Power
Wave, you must use the Setup Overlay L9770-0 to
enable the water cooler before using the system.
If the control board is replaced, the voltage calibration
and current calibration must be performed for opti-
mum performance. If the calibration is not done, the
voltage may be accurate only to within 3 volts and the
current will be accurate only to within 15 amps.
