Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
Operational Fault | 13-pin safety plug is not connected to the safety socket or radio link to control unit could not be established. | Ensure the 13-pin plug is securely inserted into the safety socket on the caravan and perform a reset if needed. | DIY Safe |
Operational Fault | Caravan battery charge is weak. | Finish manoeuvring as quickly as possible and charge the battery. | DIY Safe |
Operational Fault | Battery voltage is low (below approx. 11 V), locking the movement function. | Wait for battery recovery or charge the battery until voltage exceeds 11 V (disengagement of rollers remains possible below 11 V). | DIY Safe |
Operational Fault | System has experienced overcurrent or overtemperature. | Switch the remote control off and on again. If due to overtemperature, wait for the cooling-off phase. | DIY Safe |
Operational Fault | Caravan battery undervoltage. Drive function is locked. | Wait for battery voltage to rise above approx. 11 V (e.g., via recovery or recharging). Retracting rollers is still possible below 11 V. | DIY Safe |
Operational Fault | Overcurrent or excessive temperature. | Switch off the remote control and switch it back on. In case of high temperature, wait for the unit to cool down. | DIY Safe |
Operational Fault | 13-pin plug is not plugged into the safety socket, or radio connection to the control unit could not be established. | Check that the 13-pin plug is securely inserted into the safety socket, check batteries, or perform system reset. | DIY Safe |
Frequently Asked Questions
Q: What is the difference between the Mover SE R and TE R?
The Mover SE R is designed exclusively for single-axle caravans with a gross weight up to 2000 kg, whereas the Mover TE R is designed for dual-axle caravans with a gross weight up to 2250 kg.
Q: What is the correct gap distance between the tyres and the disengaged drive rollers?
To ensure proper function, the gap between the tyres and disengaged drive rollers must be exactly 20 mm.
Q: Can the caravan be towed with the drive rollers engaged?
No. Never tow the caravan with the drive rollers engaged, as this can cause severe damage to the tyres, towing vehicle, and drive assemblies.
Q: What should I do if the electrical disengagement fails due to a discharged battery?
You can perform an emergency manual disengagement by removing the plastic cap at the rear end of the engagement motor and using the provided socket wrench (WAF 7) to rotate the hex bolt anticlockwise.
