2.2.7. Interpreting the alarm indicators

There are six (6) red LED alarm indicators at the right side of the front
panel. An indicator lights for each of the following alarm conditions:
•
HIGH DC VOLTAGE: DS13 lights whenever the dc output voltage
exceeds the specified alarm voltage setting. See Section 2.3.4 to learn how
to adjust the HVDC alarm setting.
•
LOW DC VOLTAGE: DS14 lights whenever the dc output voltage is
below the specified alarm voltage setting. See Section 2.3.4 to learn how to
adjust the LVDC alarm setting.
•
DC OUTPUT FAILURE: DS15 lights whenever the AT30 cannot provide
its full rated output voltage or its full rated output current. This alarm
setting cannot be adjusted.
•
AC INPUT FAILURE: DS16 lights whenever the ac power supply to the
AT30 is interrupted.
•
POS GND: DS17 lights whenever leakage current from the battery positive
terminal to ground exceeds a specified threshold. *
•
NEG GND: DS18 lights whenever leakage current from the battery
negative terminal to ground exceeds a specified threshold. *
* The ground fault detection sensitivity can be adjusted
from 5 to 30 k
When an alarm occurs, the indicators will light immediately. The AT30
also features a summary alarm relay with one (1) form-C contacts (TB3)
rated 0.5A / 125 Vac/Vdc. If an alarm condition lasts for 30 seconds or
longer, the summary alarm relay transfers. Under standard settings, when
the alarm condition is corrected, the corresponding relay and indicator
resets automatically. Latching alarm capability for the AT30 is available,
featured in a supplemental Operating Instructions (JA5098-00).
