Position Unsure
The controller cannot confirm the lift’s current position, so presets and automatic movement may be unavailable. This is a protective stop, not a reason to bypass a safety feature.
Safety first
Keep the lift in sight and do not use automatic movement
Keep everyone clear of the lift and boat. On X4.4, alternating orange/red identifies Position Unsure, including a selected APS that is disconnected or no longer responding. If the controller allows manual movement, use only a held control and release it to stop. Stop immediately if the displayed direction or position does not match the lift.
What you can check safely
- 1
Stop and look over the lift
Make sure the boat is stable and that no cable, line, debris, or part of the lift is caught or damaged.
- 2
Check the app and controller
Note the exact message shown and any light or sound pattern. Do not clear the message just to resume automatic operation.
- 3
Confirm normal power is available
Check only the user-accessible breaker and shore-power connection. Do not open the controller or touch electrical wiring.
- 4
Use manual movement only if needed and allowed
Keep the lift in full view, hold the movement control continuously, and move only far enough to place the boat and lift in a safe position.
Do not try to recalibrate it yourself
- Do not change the controller version or safety configuration.
- Do not reset position, limits, endpoints, or presets unless Atlantis Support gives the procedure to an authorized installer.
- Do not open the controller, move sensor parts, or alter wiring.
- Do not use presets or unattended movement while Position Unsure is shown.
Information to send with a service request
- Controller serial number and the lift location
- A photo of the message and controller lights
- What the lift was doing when the message appeared
- Whether power was interrupted or any work was recently performed
- Whether manual movement is available and whether actual movement matches the selected direction
