Working with System Faults

Functional Overview

If a system malfunction occurs, the AGM300 will detect the problem and cause its yellow FAULT LED to glow. Additionally, an external alarm device may activate and an audible alarm may sound if those features have been enabled (Pages 17 & 38).

The next time the ADM800 polls the affected monitor its yellow FAULT LED will also glow. Additionally, an external alarm device may activate and an audible alarm may sound if those features have been enabled (Pages 28 & 35).

Depending on the nature of the fault, the AGM300 may or may not continue to operate normally. Under a non- critical fault condition, the AGM300 will continue to measure and log data, but some peripheral functions may be compromised. Under a critical fault condition, action is required for the AGM300 to operate normally. The table on the following page lists the various fault conditions and explains what action should be taken to correct the problem.

Navigating to the Fault Screen

First, display the System Screen (Page 31). Next, press the key adjacent to the target AGM300 unit to go to that monitor’s AGM Setup Screen #1 (Page 37). Finally, press the FAULTS key to display the Fault Screen of the selected monitor.
