Programming Parameters
NOTE:
Common battery pack is a technical possibility. However, APC recommend separate battery pack due to a higher safety degree in con- nection with redundant/parallel operation.
The UPS system is prepared for both solutions.
4.5Parallel programming/operation
Programming parameters for advanced parallel operation
To use the advanced parallel functions the following parameters must be pro- grammed:
1.“Station number”
2.“Highest station address”
3.“Advanced power management”
4.“APM test mode active”
5.“Battery connection”
Description of settings.
1.“Station number”
•Valid station numbers:
2.“Highest station number”
•Valid station numbers:
3.“Advanced power management”
•“Disabled”: Advanced power management is inactive.
•“PARALLEL+1”: Advanced power management is activated when the system operates as PARALLEL+1, meaning that one system can be isolated without overloading the remaining systems (N systems/UPS).
•“REDUNDANT+1”: Advanced power management is activated when the system operates as REDUNDANT+1, meaning that one system can be isolated without overloading the remaining systems (N systems/UPS) with one spare system.
4.“APM test mode active”
•“No”:
•“Yes”:
5.“Battery connection”
•“Separate”: Separate battery for this UPS.
•“Common”: Common battery in a parallel system. When this setting is chosen, the highest battery temperature that can be found in the parallelled systems is used (for charge voltage compensating).
Programming guide.
Example with 3 systems in parallel with separate batteries.
•Programme the station addresses
•All UPS systems have to be programmed to “Highest station address” = 3.
•If APM should not be tested, “APM test mode active” must be “NO”.
•If a system is isolated due to service the station numbers must be reprogrammed for the remaining active systems starting with number 1 and ending with max. number of active systems. No numbers must be left out in this sequence. Fur- thermore “Highest station address” must be changed to number of active UPS’s in parallel.
