How to Troubleshoot P5 AC Inverters Yasgawa Omron to Board Level

Power inverters -- such as the Yasgawa Omron P5 -- are used to convert an electrical current from alternating (AC) to direct (DC). These inverters can be used with a wide range of electrical devices, such as pulse generators, solar panels, and batteries. If you believe that there is a problem with one of the boards on your inverter, you can easily troubleshoot the device by reading the troubleshooting code it displays.

Instructions

- 1
  Turn your inverter on and read the troubleshooting code that is displayed on its screen.
- 2
  Interpret the troubleshooting code based on the information that is in your inverter's manual. For example, a code of "PGO PG Open" indicates that feedback pulses are not being received by the inverter's PG board.
- 3
  Perform the corrective action that is indicated by your manual. For example, in the case of a "PGO PG Open" troubleshooting code, you must check the wire that connects the pulse generator to the inverter. Make sure that the wire is not damaged and is connected securely.
- 4
  Take your inverter to an electronics repair service to have the inverter board in question replaced. (Perform this step only if your troubleshooting action does not fix the inverter.)
