Modbus 485 and Modbus IP Protocols - UPS Systems
133 Liebert® IntelliSlot® Modbus/BACnet IP
Frame Capacity Total system capacity supported when the maximum number of power modules
are installed.
Frame Fan Fault The frame top outlet fan has failed.
Inverter On/Off State inverter on/off state
Inverter Shutdown - Overload The inverter has shutdown due to a sustained overload
Inverter Status
Status of the inverter output. Active means the inverter is online with regulated
output voltage and ready to power the load. Inactive means the inverter is offline
and not ready to power the load.
Loss of Redundancy The system has an insufficient number of power modules to provide redundancy.
Low Battery - Shutdown Imminent If active and guaranteed shutdown is enabled, a low battery reserve condition
exists that will shutdown the UPS.
Low Battery Warning Time When battery time remaining falls to, or below, this value the low battery alarm is
activated.
Manual Battery Test Command to initiate a manual battery test.
Maximum Load Alarm Limit Maximum load [VA] supportable without a 'Maximum Load Alarm' condition.
Maximum Load Alarm Maximum load alarm indicating load setting has been exceeded.
Module Operating Status The operati ng status for this Battery Module.
Module Operating Status The operati ng status for this Bypass Control Module.
Module Operating Status The operati ng status for this Charger Module.
Module Operating Status The operati ng status for this Power Module.
No Load Warning Current Threshold If the output current is below this number of amps for a period of [No Loa d Warning
Delay] time, the [No Load Warning] will become active.
No Load Warning Delay If the output current is below the [No Load Warning Current Threshold] number of
amps for this period of time, the [No Load Warning] will become active.
No Load Warning
Indicates the UPS has output voltage but the output current is below a set
threshold [No Load Warning Current Threshold] for a set period of time [No Load
Warning Delay].
Number of Active Battery Strings The total number of active battery strings.
Number Of Active Power Modules The total number of active power modules.
Number of Battery Strings With
Warnings The total number of battery strings with warnings.
Number of Discharge Cycles The highest number of battery discharge cycles among all installed Battery
Modules.
Number of Discharge Cycles The total number of battery discharge cycles for the Battery Module since it was
made.
Number of EBC Installed The total number of Extended Battery Cabinets installed.
Number of Failed Battery Strings The total number of failed battery strings.
Number Of Failed Power Modules The total number of failed power modules.
Number of Installed Battery Strings The total number of battery strings installed.
Number of Installed Power Modules The total number of Power Modules installed.
Number Of Power Modules With
Warnings The total number of power modules with warnings.
Number Of Transfers To Bypass The total number of transfers to bypass from inverter since system startup.
Output Load on Maint. Bypass The output power is supplied by the maintenance bypass
Output Off Pending Output off pending - shutdown imminent.
Output On Delay When a value is written to this point the output will be turned on after the specified
time has elapsed.
Output Overload An overload exists on the output.
