(retransferred) to the UPS. How and when the load is returned to the UPS depends on several factors: how long the overload lasted, how many overload conditions occurred before transfer, whether there is an imminent failure of any part of the UPS, etc. Refer to 3.4 - Automatic Operations.
In the unlikely event of a fault within the UPS, the SCC control logic, which continuously monitors all critical circuits within the UPS system, transfers the load to bypass without interruption and simultaneously sets off local and remote alarms. If a fault is detected in an individual UPS module, that module is automatically disconnected from the critical bus and shut down. A Module Off Line status message will appear at the SCC display. The module can be manually returned to service when the fault has been corrected.

The Series 600T UPS display system provides precise monitoring of the UPS, fast alarm response, and quick troubleshooting. For easy manual operations,
The system software allows the operator, or Liebert Global Services, to enter application specific information. Overload, overvoltage, battery discharge, and shutdown limits can be set by the operator. In effect, the software is tailored for each site.
The UPS system protects critical equipment from source power disturbances and outages, load faults, and UPS malfunctions. This triple protection virtually eliminates computer and computing equipment downtime as a result of utility source power problems.
