Troubleshooting Error 101 (RCD Fault 6mA)
Issue description
Error 101 indicates a ground fault detected by the DC detection system (RCD 6mA). This knowledge article outlines steps to troubleshoot and resolve the issue.
Step 1. Update the firmware
Ensure the charger firmware is updated to the latest version.
Step 1.1 Reboot test
Turn the charger off for 10 seconds, then power it back on.
Does Error 101 reappear?
- Yes, Proceed to step 1.2
- No, Issue has been resolved
Step 1.2 In case of an Eve Double, perform a flat cable swap
Does the error move with the cable?
- Yes, then the old DC ring is defective
- No, then the controller board may be defective
Step 1.3 In case of Eve Single, Replace the DC ring and cable
Connect a new DC ring and flat cable. Does the error disappear?
- Yes, the old DC ring is defective
- No, there may be a controller board defect
Step 1.4 RCD Type-B Configuration (Eve Double)
In some countries Eve Double charging stations have been manufactured with RCD Type-B and do not include a 3-phase filter RCD (6mA). These units use jumpers instead.
Step 1.5 Jumper Check
If RCD Type-B is used, verify that jumpers are correctly placed in the right location on the control board.
Step 1.6 Reboot Again
After completing the above steps, reboot the charger.
Does Error 101 still appear?
- Yes? Then proceed to step 1.7
- No? Issue has been solved
Step 1.7 Component Replacement
