Vertiv™ NetSure™ Control Unit (NCU) User Manual
voltage of any battery string has an abnormal value. The alarm is issued when the difference between any block voltage and
a reference voltage is greater than the value of the block voltage difference setting.
• EIB-2 Block Voltage Diff (Mid): This menu item appears if “Mid Point” is selected above. The “EIB-2 Block Voltage Diff
(Mid)” setting selects the alarm threshold for battery midpoint monitoring. The NCU issues an alarm when any battery
midpoint voltage of any battery string has an abnormal value. The alarm is issued when the difference between any battery
midpoint voltage and a reference voltage is greater than the value of the block voltage difference setting.
• EIB-2 Block In-Use Num: Number of 12V battery blocks being used.
• Charging Efficiency: Value used to calculate remaining capacity of the battery.
• Time 0.1C10: Discharge time with a discharge current of 0.1C10.
• Time 0.2C10: Discharge time with a discharge current of 0.2C10.
• Time 0.3C10: Discharge time with a discharge current of 0.3C10.
• Time 0.4C10: Discharge time with a discharge current of 0.4C10.
• Time 0.5C10: Discharge time with a discharge current of 0.5C10.
• Time 0.6C10: Discharge time with a discharge current of 0.6C10.
• Time 0.7C10: Discharge time with a discharge current of 0.7C10.
• Time 0.8C10: Discharge time with a discharge current of 0.8C10.
• Time 0.9C10: Discharge time with a discharge current of 0.9C10.
• Time 1.0C10: Discharge time with a discharge current of 1.0C10.
• Clear Abnormal Bat Current: Clears an abnormal battery current alarm. The only selection is Yes. Once Yes is selected
and confirmed, the alarm clears.
ECO Tab Programmable Parameter Descriptions
• ECO Mode: Enables or disables the Energy Optimization Mode feature for all rectifiers. When enabled, the following
parameters can be set.
ALERT! The Energy Optimization Mode should NOT be used in systems that operate without batteries.
NOTE!
If the battery is ever disconnected, disable Energy Optimization Mode until the battery is reconnected.
Best Operating Point: Percent of full load capacity that the rectifiers operate under in the Energy Optimization mode.
Load Fluctuation Range: If load fluctuation is less than this value, rectifiers are not turned on or off for Energy Optimization.
System Energy Saving Point: Energy Optimization is disabled if the load is greater than this setting.
Cycle Period: This is the time period that rectifiers are turned on and off to maintain an equal operating time for all rectifiers
in the system.
All Rects ON Time: Time all rectifiers are turned on at the end of the “Cycle Period”.
