Anti-Entrapment System
The anti-entrapment system is designed to detect patient entrapment between
the base and deck when the deck is lowered, or is placed into tilt or Auto-Chair.
The system is permanently active and cannot be switched off.
Figure 30: Anti-entrapment sensors and beam
There are four infrared sensors (1), one above each castor, which generate an
invisible beam around the base of the bed (3).
If the beam is interrupted (example: by a patient’s limb) while
the deck is lowering, the deck stops moving, lifts slightly to
allow the obstruction to be cleared, and the weighing system
display reads AES.
In addition, the AES indicator LED on the ACP lights.
Upward movement of the deck is not affected.
The anti-entrapment system may also be triggered if the
beam is interrupted by bed linen, etc.
Clean the lenses (See Figure 30, item 2) of the infrared sensors
regularly using a soft dry cloth.
