Operational Fault | Overload of the power electronics (e.g., overloaded caravan, excessive gradient). | Interrupt the power supply for at least 20 seconds, then restore power. | DIY Safe |
Operational Fault | Weak battery in the maneuvering system. | Check the maneuvering system battery; charge or replace it if necessary. | DIY Safe |
Operational Fault | Incorrect tire pressure, worn tire tread, or incorrect roller-to-tire distance. | Check and adjust tire pressure, check tire tread, disengage rollers, and measure the distance between the tire and drive roller (must be 20 mm). | DIY Safe |
Manoeuvring system not working | Power supply issue, green LED on control unit is off, or defective fuse in the battery cable. | Check power supply and battery cable fuse (replace only with original Truma spare part). Interrupt power supply for at least 20 seconds, then restore. | DIY Safe |
Operational Fault | Overloading of the power electronics (e.g., overloaded caravan, excessive slope). | Interrupt the power supply for at least 20 seconds, then restore. | DIY Safe |
Operational Fault | Weak battery in the remote control (red LEDs flashing) or low system battery (green LED on control unit flashes). | Check and replace remote control battery, clean battery contacts, or charge/replace the shunting system battery. | DIY Safe |
Operational Fault | Power supply issue or blown fuse in the battery cable. | Check the power supply and ensure the green LED on the control unit is illuminated. Replace defective fuses only with original Truma replacement parts. Interrupt power for at least 20 seconds and restore. | DIY Safe |
Operational Fault | Overload of the power electronics due to an overloaded caravan or steep inclination. | Disconnect the power supply for at least 20 seconds, then restore power. | DIY Safe |
Mover not running | Check power supply (green LED on controller should be lit). Fuse in Mover battery connection cable may be damaged. | Replace blown fuse only with Truma original spare part (part no. 60040-00169) or interrupt power for at least 20 seconds and restore. | DIY Safe |
Operational Fault | Controller is overheated. | Disconnect power using the battery isolation switch and remove key. Allow controller to cool for at least 20 minutes before operating again. | DIY Safe |
Operational Fault | Low battery on remote control (red LED on remote flashes) or low Mover battery (green LED on controller flashes). | Check remote batteries/contacts and replace if necessary, or charge/replace the Mover battery. | DIY Safe |
Operational Fault | Incorrect tire pressure, worn tire tread, or incorrect distance between tire and drive roller. | Check and adjust tire pressure, replace worn tires, or re-measure distance to ensure it is exactly 20 mm. | DIY Safe |
Operational Fault | Power supply or remote interrupted during engagement sequence, or mechanical load relief process incomplete. | Ensure power is not interrupted and wait for indicator lights to stop flashing. Alternatively, use a socket wrench to manually turn the Mover approximately 2 turns clockwise and retry. | DIY Safe |
Mover does not work | Power supply issue or blown fuse in the battery connecting cable. | Check power supply (green LED on control unit should be lit). Replace blown fuse only with original Truma spare part (part no. 60040-00169). Disconnect power for at least 20 seconds and reconnect. | DIY Safe |
Operational Fault | Weak batteries in the remote control or weak Mover battery. | Check remote control batteries and contacts, replace if necessary. Check Mover battery charge and recharge or replace if needed. | DIY Safe |
Operational Fault | Incorrect tire pressure, worn tire tread, or improper distance between tire and roller. | Check and adjust tire pressure, inspect tire tread, and measure distance between tire and roller (must be at least 20 mm on the sides). | DIY Safe |
