Operational Fault | Control unit is overheated. | Interrupt the power supply using the battery cut-off switch, remove the key, and allow the control unit to cool down for at least 20 minutes before restarting. | DIY Safe |
Operational Fault | Remote control battery charge is too low or Mover system battery is low. | Check and replace remote control batteries if symbols flash, or check, charge, or replace the caravan battery if the green LED on the control unit flashes. | DIY Safe |
Operational Fault | Incorrect tyre pressure, worn tyre tread, or incorrect gap between roller and tyre. | Check and adjust tyre pressure, check tread and replace tyres if necessary, disengage the system, and measure the gap to ensure it is 20 mm. | DIY Safe |
Operational Fault | Power supply issue or defective fuse in the battery connection cable. | Check power supply (green LED on control unit should light up).

Frequently Asked Questions
Q: What is the maximum weight and gradient the Mover SX can handle?
The Mover SX is designed for single-axle caravans with a gross weight of up to 2000 kg. It can overcome inclines of up to 13% at 2000 kg, or up to 25% at 1200 kg.
Q: Can I use a battery charger as the power source for the manoeuvring system?
No, operating the manoeuvring system with a charger as the power source is not possible and is strictly prohibited. It must be operated with a charged 12V battery.
Q: What is the correct gap between the drive rollers and the tyres?
When the system is disengaged, the gap between the drive rollers and the tyres must be 20 +/- 1 mm, verified using the supplied 20 mm spacer plate.
Q: How do I pair the remote control with the control unit?
Ensure drive rollers are disengaged, check that 12V is supplied and the caravan plug is in the safety socket. Switch off the remote, wait for the red LED on the control unit to flash slowly after turning on power, press and hold the reset button on the control unit until the LED flashes very quickly, turn the control knob fully left, push the slide control fully forward, switch on the remote control simultaneously, and release controls within 10 seconds.
