5.4 Amplifier Module LED Indicators
There are LED indicators on the QAD-30 amplifier module to help in troubleshooting. The
LEDs indicate troubles, alarms, and statuses for components on the main board.
See Figure 58 on page 91 for the locations of the LEDs. See Table 16 for descriptions of what
the LEDs’ indicate.
An indicator of Output 1 or Output 2 implies a wiring short or a missing EOL.
