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.
There are four infra-red sensors (1), one above each castor,
which generate an invisible beam around the base of the bed
(3).
If the beam is interrupted (e.g. by a patient's limb) while the
mattress platform is lowering, the mattress platform stops
moving and the weighing system display shows
In addition, the AES indicator on the ACP lights.
Upward movement of the mattress platform is not affected.
NOTE
The anti-entrapment system may also be triggered if the beam is interrupted by
bed linen, etc.
WARNING
Clean the lenses (2) of the infra-red sensors regularly using a soft dry
cloth.
