The Pilot A2 RS 232 Events log is a syringe pump intended for the infusion of intravenous
agents at a accurate, low flow rate. The wide choice of syringes, the use of the universally
recognised control symbols and the synoptic display of the alarms contribute to making the
Pilot A2 RS 232 Events log easy to use. The adjustable occlusion detection, the correct
positioning detection and the overall syringe protection system guarantee optimum safety.
Its technical characteristics, the flow range from 0.1 to 400 ml/hr (configured at
200 ml/hr) and its excellent accuracy (+
Pilot A2 RS 232 Events log, the ideal instrument for medical services.
The Pilot A2 RS 232 Events log is equipped with a 16ko-EEPROM enabling the
memorization of 896 events. These events are available for consultation through the ISCTRL
maintenance software, 4.1 and upper version.

1.3 Precautions to be taken before use
The symbol in the concise instrument instructions guide of the device recommends that
the operator’s guide should be read complelety in accordance with standard EN 60601-1.
Fresenius Vial may in no case be held responsible for medical problems or any other
problems resulting from inadequate use of the equipment.
Refer to the User’s instructions for further details.
!
1.4 Internal safety features
As soon as it is switched ON, the device activates a continuous function inspection system.
Any internal failure or any problem related to the operating procedure in progress is detected
immediately. Nevertheless, abnormal operation of the equipment with no obvious cause must
always be reported to the qualified technicians in your establishment or our After Sales
service.
In case of single fault condition, an alarm is activated for any flow rate deviation of ± 5% in
comparison with the normal flow rate.
A second check activates an alarm in the event of deviation of 1 ml in comparison with the
anticipated infused volume, or if a flow rate deviation of ± 20% is identified. The alarm is
triggered by the most rapidly detected deviation.
The PilotA2Events log is fitted with an internal battery to continue operation in the event of
a power cut. Furthermore, a safety fuse protects the mains from further disturbance.

2.1.4Mechanical gear box unit
The mechanical base unit is composed of a motor-reducer block driving a screw-and-nut unit.
At the shaft end, the motor receives a control panel associated with an opto-electronic switch.
The mechanical base unit also accommodates a potentiometer fitted with a rack pinion
system.
2.1.5Mechanical plunger unit
The mechanical plunger unit is mounted onto the mechanical gear box. The gear box ensures
the displacement movement of the plunger through a screw / nut system.
The plunger is fitted with a disengagement control allowing to separate this from the screwand-nut system.

2.2 Functional description
From a functional point of view, the Pilot A2Events Log is composed of three subassemblies:
! A syringe position control and maintenance assembly.
! A motorisation assembly.
! An external connection assembly.
2.2.1Syringe control and maintenance assembly
The syringe if fitted into the upper case and held in position by means of a syringe clamp.
Detection of the syringe size (60 cc or 20 cc) is carried out by two opto-electronic sensors
mounted onto the syringe clamp.
The flanges switch ensures the syringe flanges are correctly positioned in the groove.
Associated with an opto-electronic sensor, the anti-siphon arm controls the piston position.
Composed of a micro-switch fitted to the plunger, an anti-occlusion system triggers an alarm
whenever force on the piston is excessive.
2.2.2Motorisation assembly
This sub-assembly moves the piston in the syringe.
It is put into motion by means of a motor-reducer unit associated with a screw-and-nut
system.
A motor rotation disk mounted on the shaft end of the motor and associated with an opto-
electronic sensor controls the rotation.
A potentiometer controls the plunger movement by means of a rack pinion system.
A micro-switch allows for control of the disengagement device.
2.2.3External connection sub-assembly
The Pilot A2 Events log has three connectors located at the rear end of the lower case:
! A 12-15 V DC, 15 W type external power supply connector.
! An RS 232 connector.
