6.0 Configure Sensors

This section outlines steps to configure the sensors to ensure they work correctly for the battery being installed on. There are general steps which need to be adjusted per the specific battery configuration.

6.1 Configure Standard Sensors

The VIGILANT® requires a single sensor for every cell voltage measured. These are considered the standard sensors. The steps below outline how to configure them.

Screenshot of the "Vigilant® Wizard - Sensors" configuration page for the Eagle Eye Power Solutions Vigilant® system. It displays a table with sensor settings for Install Order, Cell Reference, String, ELM fitted, Temperature, and +VE cell connection. The first four sensors are listed with cell references 1 through 4, temperature type set to "Post," and +VE cell connection currently set to "Not measured."

6.1.2 Install Order

A list of numbers is displayed for however many cells are on the system, starting at #1 for Sensor 1. No steps are required for this column other than to understand that each number corresponds to a sensor.

6.1.3 Cell Reference

This step assigns each sensor to a specific cell on the battery. The steps vary depending on if the battery cell numbering starts at the most positive or negative end of the string. Regardless of the cell numbering, the install order of sensors must start at the positive end of the string.

  1. When cell 1 starts at the positive end of the string: This is the default configuration shown above. The Install Order shows sensor #1 assigned to cell 1. Leave these settings as is if the cell numbering starts at the positive end of the string.
Table showing the install order of sensors (#1 to #3) mapped to corresponding cell references (Cell 1 to Cell 3), with Cell 1 labeled as "most pos" to indicate the most positive end of the string.
  1. When cell 1 starts at the negative end of the string: For this scenario, the installation should still go from positive to negative. But assigning the sensor IDs will just start at the negative cell, not including the “+1” sensor. So on a 60 cell/sensor system, the sensor on cell 60 (the most negative cell) will need to be plugged in first, you would go sequentially towards the most positive cell, but then the +1 sensor would be plugged in last.
  • For Example: On a -48V battery cell #1 is at the negative end of the string. In this scenario, sensor #1 under Install Order would be assigned to cell 24.

6.1.4 String

Select the string number that each sensor and cell are assigned to.

  1. Single string in series: If installing on a single string, the value for all sensors should be set to “1”.
  2. Series-parallel battery strings: If installing to multiple strings in parallel, select the string number that the corresponding sensors will be installed to.

6.1.5 ELM fitted?

If installing the ELM electrolyte level sensors, check the box for each VIGILANT® sensor that will be assigned an ELM. In most cases, just click the box above “ELM fitted?” to add the ELM to all sensors.

  • Note: It can take up to 30 seconds for all sensor to be assigned. During this time, the page may be unresponsive.
Screenshot of the Vigilant® Installer sensor setup page showing configuration options for each sensor. A red circle highlights the checkbox above the "ELM fitted?" column with the label “Click to select all,” allowing users to apply ELM sensor configuration to all rows. The table includes columns for install order, cell reference, string, ELM fitted checkbox, temperature measurement location, and positive cell connection type.

6.1.6 Temperature

Select from the dropdown “Post” for all standard sensors. This confirms that each sensor is measuring the negative post temperature via the temperature sensor in the harness.

  • Note: It can take up to 30 seconds for all sensor to be assigned. During this time, the page may be unresponsive.

6.1.7 +VE cell connection

This sets the type of intercell connection that each sensor will measure. For each sensor, the intercell connection is measured before the sensor. There are 3 interconnection types to select for each sensor:

  • Cable: This refers to measurement of the charger cable. For this step, select “Cable” for sensor 1 only. It will also be selected for the +1 sensor in section 6.2.
  • Strap: This refers to measurement of all the fixed length straps and can refer to a cable or bus bar. Select this for all interconnections that have a fixed length.
  • Tip: Select strap from the top dropdown first to apply strap to all sensors. Then change only the sensors which are cable or intertier after to save clicks.
  • Note: It can take up to 30 seconds for all interconnects to be assigned. During this time, the page may be unresponsive.
  • Intertier: This refers to any longer cables between rack tiers, splits, etc. These will typically have a higher resistance than the strap values.

Below is an example of how this would be set up for a typical 24-cell battery system that has a split in the rack between cell 12 and 13:

Sensor #Cell #InterconnectionInt. Type
11charger cable – cell 1Cable
22cell 1 – cell 2Strap
33cell 2 – cell 3Strap
44cell 3 – cell 4Strap
55cell 4 – cell 5Strap
66cell 5 – cell 6Strap
77cell 6 – cell 7Strap
88cell 7 – cell 8Strap
99cell 8 – cell 9Strap
1010cell 9 – cell 10Strap
1111cell 10 – cell 11Strap
1212cell 11 – cell 12Strap
1313cell 12 – cell 13Intertier
1414cell 13 – cell 14Strap
1515cell 14 – cell 15Strap
1616cell 15 – cell 16Strap
1717cell 16 – cell 17Strap
1818cell 17 – cell 18Strap
1919cell 18 – cell 19Strap
2020cell 19 – cell 20Strap
2121cell 20 – cell 21Strap
2222cell 21 – cell 22Strap
2323cell 22 – cell 23Strap
2424cell 23 – cell 24Strap
25*n/acell 24 – charger cableCable

Note: Sensor #25 is the +1 sensor which is covered in the next section 6.2.

After configuration of all the above steps, the page should look something like this:

A screenshot of Vigilant® software once sensor setup is completed.

6.2 +1 Sensor

After all the standard sensors are configured the +1 sensor needs to be added. The purpose of the +1 sensor is to measure the last connection resistance between the charger cable and the negative post.

  1. Scroll to the bottom of the page and click the + Add a sensor button.
  2. A new row will be added for the +1 sensor.
Screenshot of a sensor configuration table showing Sensor 60 and an added "+1 Sensor" labeled as Sensor 61. Sensor 60 has settings for post temperature and strap interconnect. Sensor 61 is configured with “n/a” temperature type and “Cable” for both interconnect and sense types. A blue "+ Add a sensor" button is visible below.
  1. Configure the sensor as follows:
  • Select the string the sensor will be added to. For single strings, select “1” (most common).
  • Select “Cable” for the temperature column.
  • Select “Cable” for the +VE cell connection column.

The +1 sensor will now be configured. The bottom of the sensor list should look something like this:

A sensor configuration screen showing sensor entries #56 to #61. Sensor #61 is being added with settings: String = 1, Temperature = Cable, +VE cell connection = Cable. A blue “+ Add a sensor” button and a blue “Continue” button are visible below the list.

7.0 Assign Sensor IDs

Now that the sensors are configured, the next step is to assign them IDs so that they correspond to the ID number (“Install Order” column) on the previous page. Once assigned, sensors will pass through various calibrations before the system is ready to start up.

7.1 Sensor Assignment Preparation

Before assignment starts, follow these steps to ensure the system is ready.

A web interface titled "About to start assigning" from the Eagle Eye Power Solutions Vigilant® Installer. Instructions explain how to begin sensor assignment by clicking the "Start" button. It lists requirements: no sensors connected via comms cable, only sensor #1 connected to the monitor, and sensors not yet connected to battery cells or interconnects.
  1. Make sure only sensor #1 is connected to the monitor. If you look at the monitor, only a single RJ12 cable should be connected which is the cable that will connect to sensor 1.
  2. The RJ12 cable between sensor 1 and 2 is disconnected (as shown below in blue).
  3. Each RJ12 cable between sensors thereafter are disconnected (as shown below in blue).
  4. The gray IDC connector is unplugged from the sensor. It is OK for the black IDC to be plugged into the sensor and connected to the battery (as shown below in green).
  • Warning: While it’s okay for the black IDC to be connected to the sensor, never leave just the gray IDC plugged into a sensor. This can damage the sensor.
Image showing multiple Vigilant Advanced Intelligent Battery Sensors from Eagle Eye Power Solutions mounted on a metal rack. Blue arrows highlight that the RJ12 communication cables between sensors are disconnected. Green arrows indicate black IDC connectors are plugged into the sensors. Orange connectors for gray IDC cables are visible but unplugged, emphasizing the correct setup for initializing only sensor #1 connection to the monitor.

After confirming these steps, click the Start button.

7.2 Assign Sensors

Warning: As mentioned above, the negative (black sleeved) cables must be connected before the positive (grey sleeved). Always keep this in mind when working with the sensors.

When the sensor assignment page loads, there will be 6 columns of information displayed for each sensor. This section covers the “Phase One State” column which has tasks per sensor, represented as empty boxes.

Phase One State Tasks:

  1. ID Assignment: Assigns the sensor an ID which is based on the order it’s plugged in. The first sensor connected is assigned 1, followed by 2 and so on.
  2. Sensor Compatibility: Determines that the VIGILANT® sensor firmware version is compatible with the monitor.
  3. ELM Configuration: Activates the ELM sensor and establishes communication. This box will be grayed out if no ELM is connected.
Screenshot of the "Sensor set-up" page from the Vigilant® web interface. The page displays sensor configuration data, including an "Order #" column, a "Reference" column, and a highlighted "Phase One State" section. The Phase One State shows three boxes labeled 1, 2, and 3 in red, indicating tasks completed for Sensor 1. Buttons labeled "Pause," "Start phase 2," "Clear ID," and "Send" are also visible at the top and next to the sensor entry. Instructions above emphasize connecting black (negative) cables before gray (positive) ones and describe the Phase One tasks for assigning and verifying sensor setup.

7.2.1 Connect Sensors

Preparation

  1. At the battery, connect the first RJ12 cable from the monitor to the sensor 1.
  2. When connected, the first 2 boxes under Phase One State should turn green within seconds. If an ELM sensor is connected.
  3. Wait until all the boxes are green and the sensor LED is a solid green. This confirms the sensor has been assigned and is ready for the next sensor.
  • Warning: Plugging in sensors too soon could result in duplicate IDs being assigned. If this has occurred, or if progress is stuck on a sensor, try selecting the Clear ID command and click the Send button.
Sensor setup interface showing three sensors. Sensor 1 has completed Phase One with three green boxes, while Sensors 2 and 3 are unassigned with all boxes empty. Options to clear ID and send commands are visible for each sensor.
  1. Proceed in connecting each sensor in order one by one until the last sensor has been assigned. The LEDs on all sensors should be solid green.
A gloved hand is shown connecting an RJ cable to a Vigilant® Advanced Intelligent Battery Sensor labeled as sensor 2, indicated with a red LED light. Sensor 1, which has already been assigned, displays a solid green LED. A blue label points to sensor 2 with the instruction "Connect RJ from 2 to start assignment," and another label points to sensor 1 stating "1 is assigned."
  1. If all was successful, a message will appear on the screen saying the system is ready for Phase 2.
Screenshot of a pop-up message on the Vigilant® monitor interface indicating the system is ready for Phase 2. The message instructs the user to connect the battery cables to the sensors, ensuring the negative (black sleeving) cable is connected before the positive (grey sleeving) cable, and to verify that the battery electrolyte level is above the minimum threshold.
  1. Before clicking the OK button to start Phase 2, ensure the following:
  • All IDC connections are plugged into every sensor like shown below. NOTE: The black sleeved harness (left IDC) must be plugged into the sensor first, followed by the gray sleeved harness (right IDC). Failure to do so can result in sensor damage.
  • If using ELM sensors that every cell electrolyte level is topped off.
Six Eagle Eye Power Solutions Vigilant® battery sensors mounted on a rack, each with both black and gray IDC connectors fully plugged in. A blue banner at the top reads "All IDCs plugged in before starting Phase 2," and each connector set is circled in blue. The sensors display a green LED indicator, showing they are powered and ready for configuration.

8.0 Phase 2 Calibrations

Assuming the installation of the harnesses was completed correctly, Phase 2 should involve few steps. This section covers the Phase Two State column which includes 5 tasks per sensor, represented again as empty boxes.

Phase Two State Tasks:

  1. Connection Check: Verifies that some readings (unit voltage, temperature, & strap voltage) fall within acceptable bounds.
  2. Sensor Configuration: Configures the sensor based on the provided settings.
  3. Pre-Pulse Checks: Confirms if the sensor is ready to carry out the pulse configuration.
  4. Pulse Configuration: Investigates, performs, and stores the battery & interconnect resistance information for the battery.
  5. ELM Calibration: Calibrates the ELM sensor the battery (electrolyte level must be above the minimum line to pass)
Screenshot of the "Sensor set-up" interface showing the progress of Phase Two calibration for sensor 1. The "Phase Two State" section has five numbered boxes (1 to 5), indicating completed calibration tasks. The "Pause" button is active, while "Start phase 2" is grayed out. Dropdown and send options are available for managing sensor IDs.

As Phase 2 starts, the execution of all tasks will carry out automatically. As there are no specific steps in this phase, below are some common errors that can occur and how to resolve them and complete Phase 2:

  1. Please wait, sensor is still charging: This occurs when phase 2 is started too soon after connecting the IDCs to the sensors. Wait 15 minutes and restart the phase.
  2. Could not reset ELS: This can occur randomly. It’s best to wait as it will usually resolve on it’s own. If it continues, confirm the ELM sensor is plugged in and powered on.

Once Phase 2 is completed, click the Continue button to complete the setup.

Screenshot of the Phase 2 progress screen in the Eagle Eye Vigilant® Installer interface showing sensor setup status for sensors 59, 60, and 61. Each sensor row displays eight status boxes, with most turning green to indicate successful completion. Sensor 61 shows two gray boxes, suggesting incomplete tasks. "Clear ID" dropdowns and blue "Send" buttons appear next to each sensor row. A "Continue" button is located at the bottom left.

The system will finalize the setup which can take 5-15 minutes. Once completed the system Home page will appear.

9.0 Check Measurement Data

This section will cover how to verify measurement data on the system before generating the report. For a complete walkthrough of the web-interface features, refer to the Web-Interface User Guide.

When the system first loads the Home page, the float voltage reading will report back at 0V. It takes 15 minutes for the first float voltage reading to appear.

Screenshot of the Eagle Eye Power Solutions Vigilant web interface Home page for a 125V battery system. Two large gauge dials display Battery Voltage (0.00 V) and Ambient Temperature (70.47 °F). The interface includes navigation tabs at the top for Summary, Alerts, Battery, Discharges, Snapshots, Reports, Settings, and Logout. Graphs below the gauges show Average Cell Resistance and Operating Temperature vs Life. The image illustrates initial measurement readings, noting that battery voltage will read 0V until updated after 15 minutes.

Once the voltage populates, verify the measurement data displayed on the Home page.

  • Float voltage: Confirm the float voltage reading displayed is within 1% of a manual measurement with a calibrated meter.
  • Ambient temperature: Confirm the ambient temperature seems accurate within a few degrees of what the room is at.

Next, verify the cell measurements by opening the Battery page.

  • Cell voltage: Compare against portable tester, should be within 1%.
  • Negative post temperature: Use best judgement, if a reading seems irregular investigate the surroundings for heating or cooling sources. Verify with another device if concerned.
  • Cell resistance: Compare against portable tester.*
  • Interconnection resistance: Compare against portable tester.*
Screenshot of the "Battery" page from the Eagle Eye Power Solutions Vigilant web interface displaying measurement data for 10 battery cells. Columns include Cell number, String, Cell Voltage (V), Temperature (°F), Temperature Type (Post), Cell Resistance (mΩ), Interconnect Resistance (µΩ), and Interconnect Type (Cable or Strap). All cells show consistent voltage around 2.25V, with varying resistance and temperature values. Each row includes a “Summary” button to review details. The data is used to verify system accuracy compared to portable testers.

*Note: For resistance readings, it’s recommended to export the data into Excel and plot it on a chart. Then import the data from the portable tester. Since resistance readings can vary between testers, the data may not always be the same. However, for most testers it should follow the same pattern when charted. See below example.

Two line charts comparing Vigilant and Cellcorder resistance readings across 60 battery cells. The top chart (Internal Resistance) shows stable values around 0.8–1.0 mΩ. The bottom chart (Connection Resistance) highlights spikes at cells 15, 30, and 45 in the Vigilant data.

Once all the data is verified, it’s time to set alarm limits.

10.0 Set Alarm Limits

All VIGILANT® alarm limits should be based either on the battery manufacturers voltage limits for the cell type being monitored or a percentage change on a baseline value for the parameter that is established by the installer once the monitor has been correctly set up and commissioned.

NOTE: It is the installers responsibility to set the alarms to the best of their knowledge. Please read the below section thoroughly to understand how to set the various alarm limits. Leaving alarm limits set by default can cause false alarms which can lead to return site visits.

To adjust alarms, go to the Settings page, then click the Alarms button.

Screenshot of the "Settings" page in the Vigilant® Installer interface, showing a grid of color-coded buttons for configuration options. Buttons include: Network (blue), Data Management (green), User (teal), Modbus (yellow), Alarm (red), Actions (dark gray), Discharge (gray), Diagnostics (blue), and ELM Management (green).

To adjust alarms, click the dropdown menu and go through each of the following parameters to set the Upper Critical, Upper Warning, Lower Warning, and Lower Critical Parameters. Note that only the critical limits will trigger the monitor LED and Relay 1.

A screenshot of the "Alarms" settings page from the Eagle Eye Vigilant® Installer interface. A dropdown menu is open, showing different alarm types: Cell Voltage, Post Temperature, Battery Voltage, Cell Resistance, Cable Resistance, Intertier Resistance, and Strap Resistance. Current alarm thresholds for Cell Voltage are displayed: critical at 2.37V, warning at 2.32V, warning at 2.15V, and critical at 2.13V. A warning at the top states that any individually configured alarms will be overridden by these changes.

10.1 Voltage & Temperature Alarms

The following alarms can generally be determined based on battery manufacturer spec sheets and the environmental conditions of the battery room.

  1. Cell voltage: The upper and lower limits should be based on the battery manufacturers specified limits for that cell or unit based on the specific gravity of the electrolyte. The warning limits are typically set 5% above or below the limits alarm settings.
  2. Battery voltage: The battery voltage limits are established by multiplying the cell voltage alarm settings by the number of cells in the battery.
  • NOTE: In extreme environmental conditions if the charger is set up to carry out temperature compensation it may be necessary to apply the same compensation to the alarm settings to prevent false alarms.
  1. Post temperature: The post (cell) temperature is affected by both the ambient temperature and the electro chemical reaction in the battery. The location and layout of the battery can also affect the individual temperatures, so the typical alarm setting is a 5% rise in cell or unit temperature either based on the ambient or the average of the all the cell temperatures.
  • NOTE: If in an environment without temperature controls, the limits may need to be set much wider. For example, an outdoor cabinet in a temperate climate.

10.2 Ohmic Alarms

The ohmic alarms refer to internal battery and connection resistances. These require more thought to establish limits for.

  1. Internal Battery Resistance: The ohmic value of the cell is based on the measurement of the internal resistance of the cell or unit. The VIGILANT® uses a DC pulse through the battery to calculate the value.

11.0 Generate NERC Report

The NERC report is simple to export, follow the steps below.

  1. Click the Report tab on the web-interface.
  2. Click the NERC report.
  • The Monitor report has all the same data as the NERC report but does not include any specific NERC requirements for Pass or Fail.
  1. Review the report to doublecheck that all the data is good.
  2. Click on either docx or PDF to export the report to the desired format.

11.1 Understanding the Report

Table titled "Station DC Supply TPL-001-5 Compliance Summary" showing two parameters—Battery Continuity and Station DC Supply—both marked with a green "Pass" status indicating compliance.
  1. Summary Data: Includes battery voltage, current, ambient temperature, and ground fault status.
A summary data table showing battery performance metrics: Battery Voltage is 135.47 V, Battery Current is -0.07 A, Ambient Temperature is 76.3°F, and Ground Fault status is "Pass" highlighted in green.
  1. Cable & Intertier Data: Includes any interconnection readings designated as a cable or intertier. This is to not affect the average of the strap values from the next table.
Screenshot of the "Cable & Intertier Data" table from the Vigilant® system interface. The table contains three columns labeled "ID," "Interconnection Type," and "Resistance (µΩ)." Five rows of data are displayed, showing IDs 1, 16, 31, 46, and 61 with interconnection types listed as either "Cable" or "Intertier," and resistance values ranging from 260.18 µΩ to 4524.62 µΩ. The table is used to isolate interconnection readings that differ from strap values, ensuring accurate analysis.
  1. Battery & Strap Data: Similar to the Battery page, it includes the readings for each cell voltage, resistance, temperature, and strap resistance.
Screenshot of a data table titled "Battery & Strap Data" from the Eagle Eye Power Solutions Vigilant® system. The table summarizes battery cell measurements including minimum, average, and maximum values for cell voltage (V), cell resistance (mΩ), post temperature (°F), and strap resistance (µΩ). Below the summary, individual readings are listed for Cell IDs 1 through 20. Each row displays values for cell voltage, resistance, temperature, and strap resistance, with some entries marked as "cable connection" or "intertier connection" instead of numeric strap resistance values.
