BACnet Communications - UPS Systems
Liebert® IntelliSlot® Modbus/BACnet IP 336
Intelligent Parallel Minimum Redundancy
This is the minimum Number of Redundant Modules that the system will
allow before bringing one or more modules back to normal operation and
terminating Intelligent Paralleling.
Intelligent Parallel Mode
This setting gives the user the ability to choose between different energy
consumption modes while Intelligent Paralleling is active and module is in
standby.
Intelligent Parallel Operation State This se tting is used to enable or disable Intelligent Paralleling.
Intelligent Paralleling Shutdown Delay This is the length of time the conditions for module standby must remain
satisfied before the module goes into standby.
Internal Bypass Breaker (CB3) Internal bypass breaker (CB3)
Internal Communications Failure The control has de tected a communication failure of a component on the
internal communication bus
Inverter Failure Inverter failure - inverter output is off
Inverter Inhibit - External Restart of the inverter is inhibited by an external signal
Inverter Off - External Inverter is off (operation is inhibited) due to external signal state
Inverter On/Off State inverter on/off state
Inverter Output Qualification Status inverter output qualification status
Inverter Overload Phase A Inverter is operating with an overload on phase A
Inverter Overload Phase B Inverter is operating with an overload on phase B
Inverter Overload Phase C Inverter is operating with an overload on phase C
Inverter Overload Time Remaining The calculated time remaining before inverter shutdown
Inverter Shutdown - Overload The inverter has shutdown due to a sustained overload
Inverter Static Switch SCR Short The system has detected a short across one or more inverter static switch
Silicon Controlled Rectifiers (SCR)
LBS Active - Master Th is UPS system has been selected as the functional Master Load Bus
Synchronization (LBS) system.
LBS Active - Slave This UPS system is synchronized to the output bus of the UPS system that
has been selected as the Master Load Bus Synchronization (LBS) system.
LBS Active The Load Bus Sync optio n is active
LBS Inhibited The system has detected that condi tions to perform Load Bus Sync are not
satisfied
Leading Power Factor The leading output Power Factor has fallen below a specified value
Loss of Redundancy The multi-module collection doesn't have enough modules to redundantly
support the load
Main Battery Disconnect Open Main battery disconnect is open
Main Controller Fault A Main Controller fault has been detected.
Maintenance Bypass Breaker (MBB) Maintenance bypass breaker (MBB)
Maintenance Isolation Breaker (MIB) Maintenance isolation breaker (MIB)
Maximum Auto Suspensions - ECO Mode This setting sets the maximum number of automatic ECO Mode
suspensions in a session.
