Frequency Range Limit (setting may be increased when powering with AC Generator): AC input voltage
frequency range limit. This limit establishes the acceptable input frequency range outside of which standby
operation is initiated.
Heater Mat Installed: If a battery heater mat is installed, this value can be programmed to Yes. The information
is then available for the headend.
IM ################: The serial number of the XM3 Inverter Module.
Individual Battery Voltages: List of the individual battery voltages measured from the battery sense harness
from either the status monitor card or the Smart AlphaGuard.
Input Current Limit: The maximum allowable input current. When this limit is exceeded, the maximum battery
charger current will be reduced to stay within this limit.
Input Current: The AC input current to the Power Supply.
Input Frequency: The frequency of the AC input voltage.
Input Power: The total input power in Watts
Input Voltage: The AC input voltage to the Power Supply.
Last Event: How long in days, hours and minutes (DDDD:HH:MM) since the last standby event ended. This
does not include self-test events.
Last Outage: The time the Power Supply was in standby mode during the most recent outage. This does not
include Self Test events.
Last Standby Reset: The number of days since the Total Standby Time and Events was reset.
N+1 Valid: Automatically sensed indication (Yes/No) whether a redundant voltage source has been connected to
the N+1 connector on the DOC with N+1 option.
Number of Battery Strings: Enter the number of battery strings installed here. This value is used with the Battery
Capacity setting to set some of the battery charger parameters if the Battery Strings Detection type is set to Manual.
Operating Mode: The operating mode of the Power Supply will indicate Line when it is powering the output from
the AC utility or Standby when it is powering the output from the batteries.
Output 1 Current: The AC output current from Output 1 of the AlphaDOC. This value is hidden if the AlphaDOC
is not installed.
Output 1 Overcurrent Trip level — Primary leg: Value of RMS current that causes an overcurrent trip on the
Output 1 protection relay after a specified delay. This limit is linked to counter data item Overcurrent Tolerance
Period. This parameter is only visible when the Protective Interface Module (AlphaDOC) is attached.
Output 2 Current: The AC output current from Output 2 of the AlphaDOC. This value is hidden if the AlphaDOC
is not installed.
Output 2 Overcurrent Trip level — Secondary leg: Value of RMS current that causes an overcurrent trip on the
Output 2 protection relay after a specified delay. This limit is linked to counter data item Overcurrent Tolerances
Period. This parameter is only visible when the optional AlphaDOC (Alpha Dual Output Card) is attached.
Output Current: The total AC output current of the power supply.
Output Power: The total output power in Watts.
Output Voltage: The AC voltage at the output of the power supply.
Output Voltage Regulation Mode: The XM3 will be able to function in 2 modes of output voltage regulation: Fine
and Coarse. When operating in Fine mode, the unit will maintain the tightest output voltage regulation possible.
When set to Fine mode, the unit will automatically adjust to and from Coarse mode temporarily if a) The unit switches
to inverter because of high/low line more than 2 times in a 60 day period or b) the unit switches tap relays more
than 60 times in a 60 day period. The unit will then automatically adjust back to Fine mode if there are less than
2 inverter transfers for high/low line and less than 15 output tap switches in a 60 day period. When operating in
Coarse regulation - Wider output voltage regulation window - Switches taps as few times as possible. Will never
automatically adjust once it is selected. Both of these modes are user selectable in the PWR CNFG Menu.
