| Description | UPS on battery: Deep momentary sag. |
| Event Information | This information from some newsgroups may help you: ------------------------------------------------------------------------------ The UPS has switched to battery power due to one of the following situations: 1. High input line voltage: The current line voltage is greater than the voltage limit set as the High Transfer Point. 2. Low input line voltage: Due to a temporary but severe reduction of line voltage (such as a brownout), the current input line voltage is lower than the low voltage limit set as the Low Transfer Point. 3. Blackout: The UPS is receiving no AC power. 4. Small or deep momentary power sag. 5. Small or large momentary power spike. 6. Simulated power failure. The Simulate Power Failure menu option of the Diagnostics menu was selected. 1. Any of the following conditions cause your UPS to go into bypass mode: 1. Internal temperature over limit: The internal UPS temperature of a Matrix-UPS exceeds the acceptable limit. 2. Battery charger failure: The Matrix-UPS battery charger failed and needs repair. 3. Severe DC imbalance overload: The Matrix-UPS inverter needs repair. 4. Output voltage outside limits: The output voltage of the Matrix-UPS is outside safe limits. 5. Top module fan needs repair: The Matrix-UPS fan in the top module is faulty. |
