Travel Fault

Presentation of the potential causes for the above mentioned fault and prescribed corrective actions.

Handling actuator cables and connections while the ACM is powered could cause injury or death. There equipment operate under extremely high voltage. Always turn off the system power by unplugging ACM power cord before.

You must ask D-BOX Support authorization prior opening the main cover of an ACM. Opening the main cover of an ACM without formal authorization voids the warranty.


Potential Cause Corrective Actions
Travel measure during the search-stop procedure is too large or too small. This is normally caused by an external body preventing the actuator to move. Alternative causes of this fault are :
  • Actuator mechanics extreme wear (check if actuators are ‘’jumping in their cups’’ or platform is pulled on the ground when moved around);
  • Broken actuator c-clip because actuator has receive an anormal choc (pulling on the actuator, bad tying-down of the system during transport);
  • Wear on actuator bearing (check if actuators are ‘’jumping in their cups’’ or platform is pulled on the ground when moved around);
  • Bad communication with encoder.
  1. Power off the haptic system.
  2. Do a visual inspection to make sure nothing is blocking the actuator travel. 
  3. With power still off, support the platform in order to gain access to the actuator piston and pull it out of its body slowly until the entire piston is out of the body and than slowly push it back in. This could wake up a ''dormant'' actuator.
  4. Try removing the actuator from it's integration (chair, simulator, rig), including captive ending if any, and check if the fault repeats itself. If not, the issue points toward the integration.
  5. With the actuator removed, if you have access to another (good) actuator, disconnect the defective actuator from the ACM and reconnect the good one.

    • If error persists on the good actuator, please contact support for further investigation.
  6. If error does not persist on the good actuator,  reinstall the good actutator in its integration (chair, simulation, rig) and check if error persist.
    • If error persist, the issue points toward the integration.
    • If error does not persist, replace/repair the faulty actuator.
