The alarm conditions that cause the History Status buffer to stop gathering new data are:
SCC | Module |
Auto Transfer to Bypass | DC Cap Fuse Blown |
Output | DC |
Output | Inverter Fault |
Overload Transfer | Low Battery Shutdown |
| Overload Shutdown |
| |
| Rectifier Fuse Blown |
| Reverse Power |
Note that the Emergency Off alarm will also freeze the SCC History Status buffer with the Auto Transfer to Bypass alarm (if the load is on the UPS system when the alarm condition occurs).
The History Status buffer does not resume collecting new frames until the fault is cleared and the Alarm Reset pad is pressed for 15 seconds (or until the screen clears).
Operation 45
