TEST PROCEDURE

1.Turn main power OFF.

2.Perform Input Filter Capacitor Dis-chargeproce- dure detailed in Mainten-ance section..

3.Connect a shorting conductor across terminals 14 and 53 of Protection Board.

4.Set an ohmmeter to X1000 range and place probes on terminals 9 (+) and 12 (-) of one Switch Board. The meter will show the Capacitors charging up and may take a minute or so to stabilize. The final meter reading should not exceed 8600 ohms (8.6 on the scale).

5.Test the other Switch Board the same way.

NOTE: Repeat the Input Filter Capacitor Dis-chargeprocedure.

6.Remove the shorting conductor set up in step 3.

7.Install 5-amp fuses in the input supply fuse holders.

NOTE: These fuses should be installed to protect against excessive current flow caused by a short circuit during the procedure.

8.Turn on the machine.

9.With the output free of a load, check the open cir- cuit voltages of the output.

10.Connect the machine for 440- or 575-volt opera- tion.

11.With the output free of a load, check open circuit voltages of the output. Voltage should be 70 VDC.

12.Remove the 5-amp fuse from the input supply fuse holders.

13.Install 20-amp fuses and test under load.

NOTE: A resistive-type grid load bank is recom- mended.

14.Perform Retest After Repair.
