5.4.4 Optional EIB (Controller Extended Interface Board) Connections (if required)

The optional EIB (Controller Extended Interface Board) provides additional connection points for voltage and current inputs,
programmable relay outputs, and temperature probes. The EIB extended interface board is mounted inside the distribution cabinet.
Refer to Figure 5.2.
Current Inputs, Voltage Inputs, and Programmable Relay Outputs
Current input, voltage input, and relay output leads are connected to screw-type terminal blocks located on the EIB. Recommended
torque for these connections is 2.2 in-lbs. Refer to Figure 5.5 for terminal locations. Refer to Table 5.6, Table 5.7, and Table 5.8 for pin-
out information.
Current Inputs
Connect up to three (3) shunt inputs to the EIB. Observe proper polarity. Refer to Figure 5.5 for terminal locations and Table 5.6 for
pin-out information.
Refer to the NCU Instructions (UM1M830BNA) and program the shunt input parameters found in the EIB menu.
NOTE!
The shunt needs to be installed in the hot (-48V) bus. Connect the plus side of the shunt to the positive shunt input
on the EIB. Connect the negative side of the shunt to the negative shunt input on the EIB.
Voltage Inputs for Battery Block and Battery Midpoint Monitoring
The NCU can monitor battery blocks (12V blocks) or midpoint battery voltage of battery strings connected to the EIB. The EIB
provides a total of eight (8) DC voltage inputs for these connections. An alarm is issued when either battery block voltage or battery
midpoint voltage is abnormal. Refer to Figure 5.5 for terminal locations and Table 5.7 for pin-out information.
Refer to Figure 5.6 for connection details. Refer to the NCU Instructions (UM1M830BNA) and program the following parameters
found in the EIB menu.
NOTE!
When using Battery Block Monitoring, you must make connections to all blocks.
•
Battery Block Monitoring
Voltage Type: Set to "48 (Block 4)". This selects the EIB to monitor up to two (2) 48V battery strings with four (4) 12V
blocks per string.
BlockVDiff (12V): This menu item appears if "48 (Block 4)" is selected above. Set to the alarm threshold for battery block
monitoring per site requirements. The NCU issues an alarm when any block 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.
Block In-Use: Set to the number of 12V battery blocks being used.
•
Midpoint Monitoring
Voltage Type: Set to "Midpoint". This selects the EIB to monitor the midpoint voltage of up to eight (8) battery strings.
BlockVDiff (Mid): This menu item appears if "Midpoint" is selected above. Set to the alarm threshold for battery midpoint
monitoring per site requirements. 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.
Block In-Use: Set to number of 12V battery blocks being used.
