8. Operation Lynx Shunt VE.Can
The Lynx Shunt VE.Can is active as soon as power is applied to the input (battery side) of the Lynx Shunt VE.Can.
The Lynx Shunt VE.Can monitors the state of charge of the battery and monitors the fuse.
LED indications
The basic Lynx Shunt VE.Can operation status is displayed via it power LED. See below table for the information displayed via the Power LED.
Power LED | Description |
|---|---|
Solid green | Lynx system is OK |
Solid red | Main fuse is blown |
Solid orange | An alarm is active |
Blink red | Hardware failure |
Blink red/green | Calibration error |
Blink green fast | Initializing |
Blink green slow | Firmware update |
Blink orange | Firmware failure |
GX device indications
Operational data is displayed on the connected GX device. This includes data such as battery voltage, battery current, state of charge and so on.
See below table of all monitored parameters.
Parameter | Description | Unit |
|---|---|---|
Battery voltage | Displays the voltage of the battery | Volts |
Battery current | Displays the current that flows into or out of the battery | Amps |
Battery energy | Displays the power that flows into or out of the battery | Watt |
State of charge | The state of charge indicates the percentage of the battery capacity that is still available for consumption. A full battery will show 100 %, and an empty battery will display 0 %. This is the best way to see when the batteries need to be recharged | Percentage |
Consumed AmpHours | Displays the energy consumed since the battery was last fully charged | AmpHours |
Time to go | Displays the estimated time, based on the current load, before the batteries need to be recharged. | Hours and minutes |
Relay state | Displays the state of the relay. On means that the relay contacts are closed, off means that the relay contacts are open. | On/off |
Alarm state | Displays if an alarm is active or not | Ok/Alarm |
Battery temperature | Displays the battery temperature | Degrees Celsius |
Firmware version | The Firmware version of this device | Number |

Deepest discharge | The deepest discharge in Ah. | AmpHour |
Last discharge | The depth of the last discharge in Ah. This value will be reset to 0 when the State of Charge reaches 100 % again | AmpHour |
Average discharge | The average discharge over all the cycles counted. | AmpHour |
Total charge cycles | Every time the battery is discharged below 65 % of its rated capacity and charged back to at least 90 %, one cycle is counted. | Number |
Number of full discharges | The number of times the battery has been discharged to a 0% state of charge. | Number |
Cumulative Ah drawn | Records the total energy consumed over all charge cycles. | AmpHour |
Minimum voltage | Lowest voltage measured. | Voltage |
Maximum voltage | Highest voltage measured. | Voltage |
Time since last full charge | The time that has elapsed since the battery was last fully charged. | Seconds |
Synchronisation count | The number of times the Lynx Shunt has automatically synchronised. | Number |
Low voltage alarms | The number of times a low voltage alarm has occurred. | Number |
High voltage alarms | The number of times a high voltage alarm has occurred. | Number |
Clear history | Press to clear all historic data. | Press to clear |
Alarms and the alarm relay
In case of an alarm, a message is sent to the GX device and the VRM portal and/or the alarm relay is activated.
The alarm conditions are:
Battery state of charge
Battery voltage
Battery temperature
Main fuse blown
