POWER WAVE
S350
PLANAR TRANSFORMER RESISTANCE TEST
PROCEDURE
1. Remove the input power to the Power Wave S350 machine.
2. Perform the Case Cover Removal and DC Link Capacitor
Discharge Procedure.
3. Locate the planar transformer. See Figure F.20.
4. See Figure F.21 for test point locations. See Wiring Diagram.
5. Using the ohmmeter, check the resistances per Table F.10. See
Wiring Diagram.
6. If the resistances are correct per Table F.10 then the planar
transformer is OK.
7. If any of the tests fail, perform the Switch Board Removal And
Replacement Procedure.
8. Perform the Case Cover Replacement Procedure.
