Introduction
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 simul- taneously activates 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.
If the
The Series 610 UPS display system provides precise monitoring of the UPS, fast alarm response and quick troubleshooting. For easy manual operations,
System software allows the operator or Liebert Global Services to enter application specific informa- tion. Overload, overvoltage, battery discharge and shutdown limits can be set by the operator. In effect, UPS operations are 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 equip- ment downtime as a result of utility source power problems.
