POWER WAVE PC BOARD

REPLACEMENT CALIBRATION

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.
