5.Turn on the Power Wave 455/R. Check for the correct DC supply voltage to the current transducer at plug J8. See Figure F.11.
A.Pin 2 (lead 212+) to pin 6 (lead
B.Pin 3 (lead
If the DC supply voltages are not present, the control board may be faulty.
6.If both of the supply voltages are low or missing, check the associated leads between plug J8 and current transducer plug P91 and the Control Board.
NOTE: The machine can be triggered by jumpering pin 1 to pin 2 at receptacle S7. See Figure F.12.
7.With the Power Wave 455/R triggered, check the feedback voltage from the current transducer. The current feedback voltage can be read at plug J8 on the Control Board.
A.Pin 1 (lead 211) to pin 6 (lead 216) should read 2.0 VDC (machine loaded to 250 amps).
