10 TROUBLESHOOTING

10.1 Functionality issues

10.1.1 Unit is dead, no lights on

On first connection the blue LED on the SmartShunt should be blinking. If this is not the case check the fuse in
the Vbatt+ cable and also check the cable itself and its terminals.
Please note that the blue LED on the SmartShunt can also be off when Bluetooth has been disabled. The
SmartShunt appears to be dead. See paragraph 10.2.1: "Cannot connect via Bluetooth" for instructions on how to
fix this.
In case the temperature sensor is used:
• The temperature sensor M8 cable lug must be connected to the positive pole of the battery bank (the red wire
of the sensor doubles as the power supply wire).
• Check the fuse in the positive (red) cable.
Make sure the correct temperature sensor is used. The MultiPlus temperature sensor does not work with the
•
SmartShunt.
Make sure the temperature sensor has been connected the right way. The red cable should connect to the
•
SmartShunt Vbatt+ terminal and the black wire to the Aux terminal.
See paragraph 3.4.3: "Aux connection for temperature monitoring" for connection instructions and a wiring
diagram.

10.1.2 Auxiliary port not working

Check the fuse in the Aux cable and also check the cable itself and its terminals.
In case the starter battery is being used: make sure that both battery banks have a common negative. See
paragraph 3.4.1: "Aux connection for monitoring the voltage of a second battery" for connection instructions and a
wiring diagram.
In case the temperature sensor is used:
The temperature sensor M8 cable lug must be connected to the positive pole of the battery bank (the red wire
•
of the sensor doubles as the power supply wire).
• Check the fuse in the positive (red) cable.
• Make sure the correct temperature sensor is used. The MultiPlus temperature sensor does not work with the
SmartShunt.
• Make sure the temperature sensor has been connected the right way. The red cable should connect to the
SmartShunt Vbatt+ terminal and the black wire to the Aux terminal.
See paragraph 3.4.3: "Aux connection for temperature monitoring" for connection instructions and a wiring
diagram.

10.1.3 Can't change settings

Settings can only be changed if the SmartShunt is running on the most up to date firmware. Update to the latest
firmware with the VictronConnect App.

10.2 Connection issues

10.2.1 Cannot connect via Bluetooth

It is highly unlikely that the SmartShunt Bluetooth interface is faulty. Some pointers to try before seeking support:
• Is the SmartShunt powered up? The blue light should be blinking. If the blue light is not blinking see
paragraph 10.1.1: "Unit is dead, no lights on".
