Sensors in the mobilis RC
The sensors for 0 position in the RC table models are
positioned next to the cylinders for Trendelenburg and for
lateral adjustment. The sensor for height adjustment is
positioned below the lateral adjustment cylinder. The
sensor for back section adjustment is installed inside the
left hand side of the seat section frame.
The sensors are connected to a green terminal box. The
terminal box for the sensors is installed below the
Trendelenburg cylinder. You will find details concerning
the cabling of the terminal box and the colour code for
the connections in the chapter “Cabling of the sensors in
the mobilis RC30/40 models” on page 78.
Checking the functions of the sensors
The functional state of the sensors or of the terminal box
can be checked by means of the LEDs at the sensors
themselves and at the terminal box next to the
corresponding connections. The LEDs at the sensor and at
the terminal box should flash up as soon as a piece of
metal, e. g. a screwdriver, is positioned in front of the
sensor. The LED of the sensor for back section adjustment
inside the seat section frame is covered.
The operating table is adjusted into horizontal and lowest
position by pressing the 0 key on the hand-held control
unit or on the foot control unit. The components of the
operating table will return into initial position one after
the other in following order: back section (RC 40 model
only), lateral tilt, Trendelenburg adjustment, height
adjustment. In case one of the sensors is defective or not
adjusted correctly, the table will move into the end
position of the relative function, and the following
positionings are no longer activated.
Adjusting the sensors
Each of the sensors for lateral adjustment, for
Trendelenburg adjustment and for height adjustment are
fixed to an angle bracket inside an oblong hole. If 0
position is activated, the sensors for lateral adjustment
and for Trendelenburg adjustment will respond to a
second angle bracket. The height adjustment sensor is
activated by means of the cross-bar of the mobile base. If
one of the sensors does not respond while 0 positioning
is being carried out, the sensors can be readjusted after
loosening of the fixing screws. The distance between the
sensor and the second angle bracket or the cross-bar
must not exceed 5mm.
