2.3.4. Setting the Alarms

After you save the equalize timer setting, the Edit Mode automatically
prompts you to adjust the settings of the high dc voltage and low dc
voltage alarms. There is a red indicator light on the front instrument panel
of the AT30 for each of the following alarm conditions:
• High DC Voltage
• Low DC Voltage
• DC Output Failure
• AC Input Failure
• Positive (+) Ground Fault Detection
• Negative (-) Ground Fault Detection
When an alarm occurs, the indicator LEDs will light immediately. The
AT30 also features a summary alarm relay with one (1) form-C remote
contacts (TB3), rated 0.5A / 125 Vac/Vdc. If an alarm condition lasts for
30 seconds or longer, the summary alarm relay contacts transfer. When
the alarm condition is corrected, the relay and all indicators reset
automatically. If latching alarms/relays are enabled the relay will need to
be reset manually, see Section 2.2.7 on page 29.
The summary alarm relay also transfers when the AT30 detects certain
secondary errors, indicated by meter display codes rather than a discrete
front panel red LED. Codes E 01 through E 13, and A 01 will trigger the
summary alarm. See Section 3.2 on page 45 for all error and status codes.
