Warning

The following servicing is to be done by qualified service personnel only. To avoid electrical shock, do not service the 5725A unless you are qualified to do so.

Follow the access procedures and warnings in section 6 to open the 5725A covers.

The voltage output transistor heat sinks are at lethal voltage potential in ac v standby and ac v operate modes during normal operation, and possibly in any other mode after a failure. The heat sinks are exposed when any assembly is in the service position, and when the heat sink cover is removed.

Use only non-conductive tools, and keep one hand behind your back to avoid making a circuit through your body. If you work on a 5725A with the power cord attached, and/or you are not certain the high voltage has not bled off, do not wear a grounded wrist strap. Wearing a strap increases risk of dangerous electrical shock.

If self-diagnostics does not identify a faulty module, you can perform these manual tests. Five different fault conditions are addressed. The following numbered list describes each type of fault condition. Following that are troubleshooting tests to do for each type of condition.

1.Fault at power-up (STANDBY and FAULT indicators lit).

2.Normal at power-up (STANDBY indicator ON), but trips out when trying to enter voltage standby mode. (VOLTAGE MODE indicator momentarily lights, then STANDBY and FAULT indicators light.)

3.Normal at power-up (STANDBY indicator ON) and ACV STANDBY (ACV and STANDBY indicator ON), but trips out when trying to enter ACV OPERATE.

4.Normal at power-up, but trips out when entering current standby

5.Normal at power-up and CURRENT STANDBY, but trips out when entering current operate.
