Troubleshooting Using Front Panel Status
LED's or Status Outputs
The 465M has 4 front-panel status LED's that reflect the current operating status of the
monitor, and indicate fault conditions. There are also four relay Status Outputs on the
rear panel (or internally in the NEMA configuration) that also reflect the state of these
status LED's. See Section 4.5.3 for more information on the Status Outputs.
