Anti-entrapment system
The anti-entrapment system is designed to detect patient
entrapment between the base and mattress platform when the
mattress platform is lowered, or is placed into tilt or Auto-Chair.
The system is permanently active and cannot be switched off.

mattress platform is lowering, the mattress platform stops
moving and the weighing system display shows
.
In addition, the AES indicator on the ACP lights.
