Return to Master TOC

1.Remove input power to the V350-PRO.

2.Using the 5/16” nut driver, remove the case wraparound cover.

3.Perform the Input Capacitor Discharge

Procedure.

4.Using the 5/16” nut driver, remove the control box top and cut any necessary cable ties. See Figure F.10.

5.Locate plug J8 on the control board. Do not remove the plug from the P.C. Board.

6.Apply the correct input power to the V350- PRO.

7.Check for the correct DC supply voltages to the current transducer at plug J8. See Figure F.11.

A.Pin 2 (lead 802+) to pin 6 (lead 806-) should read +15 VDC.

B.Pin 4 (lead 804+) to pin 6 (lead 806-) should read -15 VDC.

8.If either of the supply voltages are low or miss- ing, the control board may be faulty.
