PROCEDURE

1.The voltage calibration numbers are stored in the display board. They are program- mable from the front panel using the Test and Calibration Overlay.

2.Change the PC board in question.

3.Install the Test and Calibration Overlay L9660-255 and power up the machine. See Figure 6.

4.Press the Voltage Calibration function (32). The machine should display the following:

VOLTAGE WIRE

+POLARITY (+67A)

5.Press the Enter Key (133) on the lower right side of the overlay. The machine should display the following:

ADJUST TO 30V

CALIBRATION #=XX

NOTE: Here “XX” indicates a particular cali- bration number for a given voltage sensing point.

WARNING

The machine’s output terminals will be electri- cally “HOT” when the Enter Key is pressed.

6.With the machine loaded, monitor the refer- ence voltage only (external voltmeter). It is the only important reading. Adjust the volt- age using the Arrow Keys (100 and 101) until the reference voltmeter reads 30.0 volts. Press the Enter Key.

CAUTION

WHEN LOADING THE MACHINE WITH THE CASE PARTS REMOVED, BE CAREFUL NOT TO OVERHEAT THE MACHINE.

7.Repeat the process by pressing the Voltage Calibration function again. The next volt- age sensing point (lead) may be selected by pressing the down Arrow Key (101). The above procedure must be repeated six times to set the six sensing points (leads) to 30.0 volts. The six test points (leads) are the following:

+Polarity (+67A) - Polarity (+21A)

+Polarity (+67B) - Polarity (+21B)

+Polarity - Polarity

8.If the display board is replaced or dis- turbed, perform the Sensor Calibration Test.
