Troubleshooting Calibration Problems
If, during the Calibration Procedure, a parameter is missing or non-responsive, check for proper analog
voltage levels at the points indicated in Figure 7 – HG2 Connection Details – Board Component View. Care
must be taken not to short circuit between the board test points. Warning! Line voltage potentials are
present on the board.
If the analog voltage levels are normal and the board cannot be calibrated, the board is probably
defective. Replace the board and perform the Setup and Calibration procedures.
