Monitoring Power Module Performance
The computer inside the Power Module is continually monitoring Power Module performance.
If the Power Module computer detects a problem or malfunction, the yellow wrench symbol
appears on the front of the Power Module. The yellow wrench is accompanied by an audio tone.
This is a steady or beeping tone, depending on the condition. Refer to
Handling Power Module
Alarms on page 7-29 for guidelines on handling Power Module alarms.
