2.2 Functional description
The APPLIX Pump is composed of three functional subassemblies:
n A subassembly of holding and control of giving set.
n A pumping subassembly.
n A holder subassembly with external connections.
2.2.1 Subassembly of holding and control of giving set
The giving set is installed on the top surface and maintained in position by the door.
The top surface is equipped with three detection systems:
n A sensor to control the closed door position (UC board).
n An optical sensor to detect the type of the installed giving set.
n An ultrasonic sensor to detect air bubbles presence in the giving set.
2.2.2 Pumping subassembly
The pumping subassembly includes the peristaltic mechanism of pumping.
This mechanism is composed of a camshaft performing the alternative travel of three
pushers. The travel of these pushers, managed by the CPU board, performs the liquid
displacement at the flow-rate.
A DC motor with a gear-box subassembly drives in rotation the camshaft by means of an
indexed belt.
An optical disc fastened at the camshaft end performs the rotation control.
The occlusion detection is carried out by the measurement of motor current.
2.2.3 Holder subassembly with external connections
The presence of the pump on the holder is detected by a sensor mounted on the holder and
associated to a magnet fastened inside the pump.
The holder is equipped with an RJ45 connector used for nurse call alarm or communication
with a PC.

3 Calibration menu
The calibration menu is used to perform tests and consult the different parameters recorded
in the pump.
The modification of these parameters can only be performed from a PC equipped with the
APPLIX control software. The software can be ordered by approved and qualified
technicians who have been trained.
For access to the different parameter readout, refer to "Control" chapter.
The calibration menu gives access to twenty-one sub-menus. Only thirteen are necessary for
the maintenance technician. Others are not detailed in this guide.
