• Rated Capacity: Enter the battery string’s rated capacity. After setting the battery capacity, the User should also reset the
battery capacity (battery must be fully charged). See “Setting Battery Capacity Parameters” on page 36.
Batt2 Settings Sub-Menu
• Shunt Current: Enter the battery string shunt’s current rating.
• Shunt Voltage: Enter the battery string shunt’s voltage rating.
• Rated Capacity: Enter the battery string’s rated capacity. After setting the battery capacity, the User should also reset the
battery capacity (battery must be fully charged). See “Setting Battery Capacity Parameters” on page 36.
4.1.6 LVD Settings Sub-Menu
• 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.
• HTD Recon Point: Sets temperature at which a reconnect will occur following a High Temperature Disconnect.
• LVD 1: Enables or disables LVD1.
• LVD 1 Mode: Sets LVD1 to disconnect on a voltage or time setpoint.
• LVD 1 Disc Volt: LVD1 low voltage disconnect setting (when LVD set for voltage).
• LVD1 Recon Volt: LVD1 reconnect setting (when LVD set for voltage).
• LVD 1 Time: The time period before LVD1 disconnection once an AC fail condition occurs (when LVD set for time).
• LVD 1 HTD: Enables or disables the High Temperature 1 Disconnect feature. This feature causes LVD1 contactors to open
(disconnect) if a high temperature event occurs.
• LVD 2: Enables or disables LVD2.
• LVD 2 Mode: Sets LVD2 to disconnect on a voltage or time setpoint.
• LVD 2 Disc Volt: LVD2 low voltage disconnect setting (when LVD set for voltage).
• LVD 2 Recon Volt: LVD2 reconnect setting (when LVD set for voltage).
• LVD 2 Time: The time period before LVD2 disconnection once an AC fail condition occurs (when LVD set for time).
• LVD 2 HTD: Enables or disables the High Temperature 2 Disconnect feature. This feature causes LVD2 contactors to open
(disconnect) if a high temperature event occurs.
4.1.7 AC Settings Sub-Menu
• Nominal AC Volt: Enter the nominal line-to-neutral voltage (single phase rectifier) or nominal line-to-line voltage (three
phase rectifier).
• Mains Fail Alm1: Sets the Mains Fail Alarm 1 value (percent of nominal).
• Mains Fail Alm2: Sets the Mains Fail Alarm 2 value (percent of nominal).
Corresponding Alarms:
- Phase A Voltage Low 1 (Nominal Minus "Mains Fail Alarm 1 Percent of Nominal)
- Phase A Voltage Low 2 (Nominal Minus " Mains Fail Alarm 2 Percent of Nominal)
- Phase A Voltage High 1 (Nominal Plus " Mains Fail Alarm 1 Percent of Nominal)
- Phase A Voltage High 2 (Nominal Plus "V Mains Fail Alarm 2 Percent of Nominal)
