1. OVERVIEW
1.1. General description
Information in this document only refers to devices belonging to the Master PCA. No responsibility
whatsoever can be taken by Vial Medical for any fundamental change to product specifications
(specifications, performance ratings, etc.) made by non-company personnel.
Routine repairs may be carried out by the appropriate maintenance team, at the discretion of the end user
and subject to his or her responsibility. We nevertheless recommend that Maintenance personnel first
attend a training course organised by Vial Medical.
The symbol visible on the condensed instruction guide of the device, recommends the Operator Guide
should be completely read, in accordance with the EN 60 601-1 Standard.

Please consult Operator’s guide
NT 0850 Rev.0 Page : 3
1.4. Internal safety features
The Master PCA is equipped with a continuous functions inspection system activated as soon as the
Master is switched ON. Any failure or anomaly in the procedure is immediately detected. Nevertheless,
qualified staff of your organisation or our After Sales Service should always be notified in case of
abnormal functioning ( see useful addresses, chapter 9 )
1.5. Technical characteristics
The Master PCA is controlled by a keyboard and a rotary knob. The parameters input by the user, the
infusion parameters, and parameters describing the instrument status may be visualised by means of a
graphic LCD screen.

1.5.1.8. Pressure limit
The selection values of the pressure limit threshold are changeable by configuration from the key
board.(See operator’s guide of the connected Pilot for the operating procedure and the display accuracy).
The threshold values or the pressure limits applied by default are the ones programmed on the Pilot.
1.5.1.9. Pressure management
q Occlusion pre-alarm and alarms.
q Disconnection / pressure drop alarm.
1.5.1.10. Occlusion alarm delay according to the infusion flow rate
Correspondences tables between occlusion alarm delay and programmed flow rate for three selectable
pressure limits in three pre-adjuted threshold mode. These tables shows obviously that it is very
interesting to choose, as soon as possible, the lowest alarm threshold to get the short test alarm delay.
The variable threshold mode allows to select continuously the best adapted value.

1.5.1.11. Bolus volume at occlusion ending.
When occlusion is detected, the anti-bolus system is activated. By measuring the pressing dynamic
strength, the reduction of the bolus at occlusion ending is performed according to the specific
characteristics of each selectable syringe.
This principle allows to much reduce this bolus whoever the flow rate and the alarm threshold adjustment
be.

2. ELECTRONIC BOARDS
2.1. CPU BOARD
2.1.1. Functional description
The Master PCA CPU circuit board is built around on the 80C320 microcontroler used in open mode. This
micro is equivalent to the 80C32, but its slightly modified structure gives an overall speed improvement.
Characteristics
EPROM 256 Ko
FLASH EPROM 521 Ko
RAM 128 Ko saved by a battery
EEPROM 2 Kbytes for the instrument’s configuration
WATCH DOG MAX 691 resetable and safety RAM
INTERNAL CLOCK PCF 8583P addressable by IC bus
LED Driver 16 LED's max
Keyboard Driver 16 keys max.
Display 128 x 64 pixel screen graphics
T6963C integrated controller. Manual adjustment of contrast
Attachments RS TTL Master PCA / Pilot
RS 232 PC/ Master PCA. RS 232 option
Power Supply Continuous from 5.4 V to 7.2 V, includes regulator
of slight voltage drops.
Battery power safety system for the RAM and the
internal clock 3.6V 60 mAh.
The CPU circuit board has the following functions :
• power supply and regulation of the module.
• communication with the module.
• link module for the Master PCA/ Pilot .
• keyboard.
• CPU, memory.
•
2.1.2. Regulation - Power supply
The regulation/power supply module consists of a linear regulator with a low drop out voltage of for which
the input voltage is supply by the Pilot battery and then regulated.
2.1.2.1. ON/OFF command
The ON/OFF key of the device is connected to the CD ON input line of the Pilot. A short press on this key
switch on the power supply of the Pilot. Then, the Pilot battery supplies the necessary energy to the
Master PCA (mains or battery).
When pressing ON/OFF button, the microprocessor knows the status of the button by reading TOFF by
the input line from U24. It prepares the switch off mode and sends the command to turn off the voltage to
the Pilot using RS 232 interface from the Pilot.

In case of breakdown of power supply, the Pilot battery provides the necessary energy to the two devices.
When the Master PCA is switched off, an internal battery saves the RAM in order to keep patient’s history,
and the internal clock continues to be supplied.
The battery is recharged when the device is in use. When the instrument is not in use, the minimum life
expectation for a fully charged battery is 2 months.
The battery voltage of the Pilot is present on the connector subD 15 points J2, connecting the Pilot to the
Master PCA.
• the minimum supplied voltage which does not provoke the resetting of the device is 5.1 V.
• the maximum supply voltage is 7.2 V

2.1.2.3. Pre-alarms and alarms
Alarms and pre-alarms are identical to those of the Pilot. The alarm status parameters of the Pilot is
transmitted via the RS 232 interface to the Master PCA.
2.1.2.4. Battery voltage levels
This voltage is measured at the battery terminals lead of the Pilot.
• pre-alarm : 5,8 V min / 6,0 V max.
• alarm : 5,6 V min / 5,8 V max.
The voltage drop between the input of the instrument’s regulator and the battery is due to the internal fuse
of the Pilot and various connections between. This voltage drop is 0.5 V max. for a current of 350 mA.
• the battery voltage of the Pilot can be measured inTP4
2.1.3. Watch dog
The watch dog manage the RESET line, the rising voltage of VP of the circuit voltage Vp to safety (RAM,
INTERNAL CLOCK), the switching of the CE line of the RAM to keep the integrity of the data in the RAM
in case of drop of the power supply is broken.
The voltage V.P. is supplied by the battery BT1.
The timer is activated by the signal WDOG generated by the output socket comprised of circuit U22 (

The control of flux is carried out by a hardware link between the DTR pin of the printer to the RTS pin 8 of
the Master PCA.
• When the RTS pin is at + 12 V, the Master PCA considers that the printer is ready to receive some
text.
• When the printer is not connected, the RTS pin is set to - 12 V ; and the PCA therefore sends no text.
