Troubleshooting

WARNING

Exercise caution when using and servicing power supplies. High energy levels can be stored at the output voltage terminals on all power supplies in normal operation. In addition, potentially lethal voltages exist in the power circuit and the output connector of power supplies which are rated at 40V and over. Filter capacitors store potentially dangerous energy for some time after power is removed.

Diagnostic This section describes the diagnostic LEDs found on the RS-232 interface.

LEDs

Computer Operating Properly (COP) LEDs The RS-232 interface provides three diagnostic LEDs, located at D5, D4, and D1 on its PCB. Refer to Figure 2.3, ‘RS-232 Interface PCB” on page 18, for their locations. At present, these LEDs turn on to signal COP events for the interface's microprocessors. Issue a RST (reset) command to turn off the diagnostic LEDs.

The green COP LED at circuit designation D5 indicates that the RS-232 interface microprocessor successfully recovered from a timeout error due to a communications bus error. The event is transparent to the RS-232 communications line continues to function normally.

The red COP LED at D4 indicates that a transparent restart caused by noise in the master processor circuitry has occurred.

The red COP LED at D1 indicates that a transparent restart caused by noise in the slave processor circuitry has occurred.
