3.0 Operation, Continued
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.
