Troubleshoot procedure

The procedure helps you troubleshoot when you are find the Smappee Power box and other Charger modules in the device list but not the Solidcore and CT-Hub to do the measurements.

This usually indicates an issue on the A-line. The root cause can be related to one of the following components:

• Powerbox

• Relay board

• UTP cable

• Splitter

• Solidcore / CT-Hub

These components together form the A-line. Below you will find a step-by-step procedure to help localize the issue.

Please see the yellow line on the drawing below to know what we mean with the A-bus, you will see the line is connected to all the A-ports.

Step 0 - Make sure all is connected according to the manual

• See manuals of the products in the Applicable for section
• Make sure all RJ10 cable are firmly put in the ports
• Make sure the Solidcore or CT Hub are connected to the A port of the splitter 
• Make sure the total length of the A-bus (From Powerbox inside station to last CT Hub in the bus) is not more then 100m

Step 1 – Initial test

Connect the Solidcore or CT-Hub directly to the powerbox.

• Are the Solidcore and CT-Hub detected?

  • No: The issue is most likely related to the powerbox or the CT-Hub/Solidcore.
    Replace one of these components (recommended: CT-Hub).
    If the component is detected afterwards, the root cause has been identified.

  • Yes: The issue is likely related to the relay board, the UTP cable, or the splitter.

Step 2 – Test the UTP cable

Use a pre-made UTP cable and connect it to the relay board and the splitter.

• Are the components detected?

  • Yes: The original UTP cable is the cause of the issue, make sure you have a UTP tester at hand

  • No: The new cable does not resolve the issue. Proceed to the next step.

Step 3 – Add a splitter

Add a second splitter to the system and install it inside the charging station.

• Connect the UTP cable going to the relay board to the splitter inside the charging station.

• Disconnect the A-bus from the relay board and connect it to the A-bus of the splitter.

• Use the rear B-bus (port 3) of the relay board and connect it with an RJ-10 cable to the B-bus of the splitter.
