Alarm text | Description |
|
|
Input Out of Range | • Input (Utility) fault: Measured input voltage has exceeded the upper |
| voltage limit specification for normal operation. |
| • Input (Utility) fault: Measured input voltage is less than the lower voltage |
| limit specification for normal operation. |
| • Input (Utility) fault: Measured input frequency is outside the upper or |
| lower frequency limit specification for normal operation. |
| • Rectifier fault: Measured rectifier input current exceeds the upper current |
| limit specification for normal operation. |
| • The utility input power is not within predetermined limits. This is possibly |
| caused by over voltage, under voltage, over frequency, under |
| frequency, or over current. |
| • The utility input is not present, and detected voltage is zero. |
|
|
Internal Failure | • An attempt to automatically recalibrate the UPS has failed. |
| • Charger fault: The battery charger has failed. |
| • DC Link fault: Measured DC link voltage has exceeded the upper |
| voltage limit specification for normal operation. |
| • At least one fan in the UPS has failed. |
| • At least one fuse in the UPS has failed and must be replaced. |
| • Inverter fault: Measured inverter output voltage has exceeded the upper |
| voltage limit specification for normal operation. |
| • Inverter fault: Measured inverter output voltage is less than the lower |
| voltage limit specification for normal operation. |
| • The inverter module has failed its power up |
| test. |
| • Inverter fault: The inverter has failed. |
| • The inverter output has failed and cannot support the load. The reasons |
| for this alarm are, for example, inverter over or under voltage, over or |
| under frequency, distorted waveform, and output |
| • Inverter fault: The measured inverter output current exceeds the upper |
| current limit specification for normal operation. |
| • The inverter output voltage sensor has not been calibrated. |
| • For a parallel system, this module has detected that the sync bus is not |
| active. |
| • A test of the device EEPROM has detected a checksum failure. The |
| device either has not been programmed or contains suspicious data. |
| • A test of the device ROM has detected a checksum or CRC error. The |
| device's operating code is suspicious and should be replaced or |
| reflashed. |
| • In a |
| the firmware versions in place are not compatible with each other. |
|
|
Loss of Redundant | The agent lost communication to one of the redundant UPSs. This alarm |
Communication | appears on the management module that is still in communication with the |
| agent. If both management modules lose communication with the agent, this |
| alarm does not appear. |
|
|
Loss of Redundant Power | One of the redundant UPSs is off or on battery power. |
