Unusual or Erratic Operation
If the power supply displays any unusual or erratic operation, follow
these steps:
1. Shut the power supply OFF immediately.
2. Disconnect the power supply from the load and external
programming.
3. Test the power supply with no load, running the tests in “Step 5:
Performing Functional Tests” on page 2–11.
4. If the tests show that the power supply is functioning normally, check
all load, programming, and monitoring connections and circuits.
5. Check the AC input for correct voltage and frequency.
If the problem is not solved after you have followed this procedure, or if
the unit fails to operate correctly upon retesting, call your service
technician.
