User Manual, UM1M830BNA
Spec. No: 1M830BNA, 1M830DNA Code: UM1M830BNA
Model No: M830B, M830D Revision M, May 12, 2017
o SOLAR: If you have only solar converters in the system, set Solar Mode to “SOLAR”. Reboot the controller (see “Rebooting
the Controller” on page 31) after changing setting to SOLAR.
HTD Point: Sets high temperature limit at which LVD1 and/or LVD2 contactors will open (disconnect) if the HTD1 and/or HTD2
features are enabled. If this temperature is reached, a disconnect occurs regardless of voltage.
NOTE: This feature requires a BTRM sensor. The BTRM sensor is the sensor which is used for the High Temperature Disconnect (HTD)
Feature.
HTD Reconnect Point: Sets temperature at which a reconnect will occur following a high temperature disconnect.
Battery Tab Programmable Parameter Descriptions
Equalize/Float Charge Control: Places the system in Equalize Charge or Float Charge mode.
Float Voltage(Solar): Float charge output voltage setting for solar when the “Solar Mode” setting under “System” TAB in Web
Interface is set to either “RECT-SOLAR” or “SOLAR”.
Equalize Charge Voltage: Equalize charge output voltage setting for solar when the “Solar Mode” setting under “System” TAB
in Web Interface is set to either “RECT-SOLAR” or “SOLAR”.
Float Voltage(RECT): Float charge output voltage setting for rectifier when the “Solar Mode” setting under “System” TAB in
Web Interface is set to “RECT-SOLAR” or “Disabled”.
Equalize Charge Voltage: Equalize charge output voltage setting for rectifier when the “Solar Mode” setting under “System”
TAB in Web Interface is set to “RECT-SOLAR” or “Disabled”.
Number of Battery Shunts: Sets the number of battery shunts in the system.
Batt1 Rated Capacity: Enter the battery string's rated capacity.
Batt2 Rated Capacity: Enter the battery string's rated capacity.
Reset Battery Capacity: Resets the battery capacity calculation. The only selection is Yes. Once Yes is selected and confirmed,
the battery capacity calculation is reset.
NOTE: Only reset the battery capacity when the battery is fully charged; otherwise, the battery charge status may not be accurate.
Number of Battery Fuses: Designates the number of battery fuses in the system.
Calculate Battery Current: Selects whether or not the NCU calculates the battery current in the case of no battery shunt (load
shunt required).
Temp Comp Sensor: Select "None" for no temperature compensation, or the temperature probe [System Temp1 (bat), System
Temp2 (bat), System Temp3 (bat), IB2-1 Temp1 (bat), IB2-1 Temp2 (bat), EIB-1 Temp1 (bat), EIB-1 Temp2 (bat), SMTemp1
Temp1 (bat), …, SMTemp1 Temp8 (bat), SMTemp8 Temp1 (bat), …, SMTemp8 Temp8 (bat)] sensing battery temperature for
temperature compensation. You can also select Maximum or Average which takes the maximum or average reading of the
temperature probes [any ofSystem Temp1 (bat), System Temp2 (bat), System Temp3 (bat), IB2-1 Temp1 (bat), IB2-1 Temp2
(bat), EIB-1 Temp1 (bat), EIB-1 Temp2 (bat), SMTemp1 Temp1 (bat), …, SMTemp1 Temp8 (bat), SMTemp8 Temp1 (bat), …,
SMTemp8 Temp8 (bat)] set as battery temperature probes. When used with an SM-BRC, you can select to average the SM-BRC
temperature probe readings (Average SMBRC setting).
Comp Temp High 2: Sets the Compensation Temperature High 2 alarm point.
Comp Temp High 1: Sets the Compensation Temperature High 1 alarm point.
Comp Temp Low: Sets the Compensation Temperature Low alarm point.
Temp Comp Center: Sets the temperature at which the system operates at normal voltage levels.
