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
• Ground Fault Detection (+)
• Ground Fault Detection (-)
When an alarm occurs, the indicators will light immediately. The AT30
also features a summary alarm relay with one form-C contacts (TB3),
rated 0.5A / 125 Vac/Vdc. If an alarm condition lasts for 30 seconds or
longer, the summary alarm relay contacts transfer. This can be monitored
remotely from TB3. 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 contacts (TB3) also transfer when the AT30 detects
certain secondary errors, indicated by meter display codes (E 03, E 04,
E 06, E 07, E 08, E 09, E 10, E 12, E 13, and A 01), rather than a red
alarm light. See Section 3.2 on Page 45 for all error and status codes.
