APS Sensor Faults
APS means Atlantis Position Sensor. A sensor warning means the controller may not be able to rely on the lift position. Keep the lift stopped and arrange qualified service when the warning remains or returns.
Safety first
Stop if the reported position or direction does not look right
Do not use presets or automatic movement while a position sensor fault is active. On X4.4, alternating orange/red means position is unsure and can indicate a disconnected or unresponsive selected APS. Never bypass the warning or keep moving the lift to test it.
What to do now
- 1
Stop movement
Release the control, keep the boat and people clear, and do not request another move.
- 2
Read the app message
Record the exact alert, controller serial number, and what the lift was doing when it appeared.
- 3
Check only visible outside conditions
From a safe distance, look for obvious damage, loose mechanical parts, water, or corrosion. Do not touch the sensor, cable, controller, or wiring.
- 4
Request qualified service
Contact your installer or Atlantis Support. Authorized personnel must use the matching internal procedure in Atlantis Central.
What the warning may affect
- Automatic positioning and presets may be unavailable.
- The displayed lift position may not be reliable.
- The controller may prevent movement to protect the lift.
- A recurring fault requires inspection by a qualified installer or Atlantis Support.
