Product Release 1 Operating the Amplifier

If the amplifier faults, it usually resets itself after 4 seconds.

ON/AMP and then OPR. (You need not turn the amplifier off.)

— To display the last fault, press the FLT button and view the 7-

segment display.

— To display the last 20 faults, open the AR9500 PC application

that allows remote control over a serial interface and select

the correct COM port. Select Tools > Get fault log.

To see a complete list of possible faults, see Chapter 8,

“Diagnosing Faults.”

You can optionally control the Alpha 9500 completely from the

Microsoft

Windows

AR9500 PC application rather than the

front panel. For more information, see Chapter 6, “Operating the

Amplifier from a PC.”
