Emergency Shutdown

If your power supply is not performing as described in this operating manual, run through the procedures and checks in this section before calling your service technician. These procedures are confined to operator-level functions only and do not require cover-off servicing.

In an emergency, carry out both of these steps:

1.Shut the power supply OFF immediately.

2.Disconnect the power supply from the load.

Unusual or Erratic Operation

Troubleshooting for Operators

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.

3.Test the power supply with no load, running the tests in Functional Tests.

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 following this procedure, or if the unit fails to operate correctly upon retesting, call your service technician.

Turn to the next page for more information about troubleshooting for operators.

Use the checks in Table 3.4 to ensure that the power supply is configured and connected for normal operation.
