Glossary of Alarms
AC Fail | All rectifiers are reporting loss of AC power. |
ACD Fan Fail | The AC Distribution cooling system or fan controller has failed. |
Aux Temp High | The auxiliary temperature sensor is at a temperature above the high |
| temperature set point. |
Aux Temp Low | The auxiliary temperature sensor is at a temperature below the low |
| temperature set point. |
Aux Temp Sensor Fail | The auxiliary temperature sensor is incorrectly configured, |
| disconnected, not fitted or faulty. |
Batt Temp High | This alarm indicates either thermal runaway of the batteries or that |
| the batteries are operating at a temperature that may cause reduced |
| battery life. |
Batt Temp Low | This alarm indicates a risk to the battery standby power system. |
| Note that lower temperatures reduce the battery capacity. |
Battery Fuse Fail | The batteries may no longer be powering the load. |

| in a fully charged state. |
Equalize Active | An Equalize process is active. |
Fast Charge Active | A Fast Charge process is active. |
High Float | The float voltage is above its normal range. |
High Load | The bus voltage is higher than the range that is safe for a reliable |
| load. |
In Discharge | The batteries are discharging. |
