System Overview
Design The Vista basic is a compact volumetric peristaltic infusion pump.
Standard delivery rate range 0.1 to 999.9 ml/h with Intrafix and
0.1 to 800.0 ml/h with Vista Pump Set.
The unit is operated via a membrane keypad. It is equipped with
an LCD (liquid crystal display) for the display of the delivery rate
and the operating support of the user. Two control LEDs display
alarms, and the running of the infusion pump.

See Instructions for Use for detailed information.

System Overview
Function Two independent software-controlled microprocessor systems
control and monitor the hardware. On the basis of their functions,
they are defined respectively as a control and a function proces-
sor. Both systems work with independent clock frequencies and
have access to different program and data memories, All safety-
relevant functions are handled by both processors and the results
are counter checked (CF- and FC-latch).
The input via the keypad is fed to both processors. Additionally
the acknowledgement signal of the ON/OFF key is fed to the
mains power supply logic (voltage E/A-TAS). The function proces-
sor has also access to this logic via E/A-INT,

System Overview
Voltage Supply The voltage supply is generated either directly from mains, via the
FM plug (14 V connection to the fluid manager system), or via the
MFC connector (11 to 16 V) and as an internal supply via the in-
ternal 7.2 V NiCD battery. The mains module is available in three
versions: 230 V, 220 / 230 / 240 V and 100 / 110 / 120 V. The rated
voltage has a tolerance of + 10% to — 15 %.
Avoltage of 11 Vto 18 Vis available after transformation and rec-
tification. This voltage is fed to the battery charge circuit and the
unit supply. This is also valid for an external 12 V supply from the
MFC or FM plug. The FET V10 switches between the external and
the internal voltage supply. The transistor VIOb works as an ON/
OFF switch for the operating voltages UBS, UMOT and +5V. The
+5V supplies the complete electronics including the double chan-
nel microprocessor system. A window comparator constantly
monitors the +5V for undervoltage or overvoltage. The function is
checked during switch- on. The operating voltage UBS supplies the
stepper motor and the UMOT, the stepper motor drive.
The transistor V47 switches the operating voltage UMOT. In case
of an alarm the motor is switched off by V47. Additionally the
switching function of the transistor is checked during the switch-
on test.
The circuit has two separate assembly groups with separate sup-
ply voltages UBA and UBB. The ON/OFF circuit has a retriggerable
delay switch: off. A follow-up charging circuit drives the transis-
tor V10b.
The alarm logic (operating voltage UBB) is an RS latch. This is set
when the unit is running and activates the alarm circuit. The
alarm buzzer and drive are also driven by UBB. The ON/OFF circuit
is activated and the voltage supply is switched on by pressing the
ON/OFF key. The alarm latch is reset simultaneously. A function
test of the voltage monitoring, motor circuit and alarm activation
is performed, The voltage supply is maintained by cyclic self-hold-
ing pulses fed to the logic. The alarm latch is also activated.

Mains Operation
Vista basic 950971 Rev A (5/04)
When the unit is connected to mains the unit supply voltage is
switched on for the duration of the switch- off delay time. lf the
microprocessor recognizes a sufficient mains voltage for the
charging,thevoltagesupplyismaintained.Inthiscaseonlyabat-
terybalanceiscarried out, becauseakeywasnotpressed. Theac-
tual battery capacity and the battery operating hours are
displayed in the LCD. The unit is switched off when the ON/OFF
key is pressed for at least 2 seconds. Thereby the self- holding is
triggered and the alarm latch is reset with a delay. After another
20 seconds the unit is switched off, because the pulses are miss-
ing. If the Vista basic is switched off in mains operation with the
ON/OFF key, the internal mains voltage is still present.
In mains operation the battery function is checked during the
switch-on test. Therefor the charge and discharge current is mea-

System Overview
sured and the charging of the battery is interrupted for the dura-
tion of the measurement.
Battery Operation
The battery function is monitored by the following data: charge
current, discharge current and time, and self-discharge time. In
battery operation the battery function is checked during the
switch-on test. The theoretical load condition is read from the
clock module of the battery. Then the battery is connected to UBS
and the voltage is measured. If the minimum requirements are not
reached a battery alarm is activated.
Alarm Circuit
The alarm generation consists of:
- Standstill of pump due to switch- off of MS (motor circuit}
and UMOT (motor operating voltage}
- Audible alarm due to the drive of the buzzer or the ou 中
speaker via ALA- AK (control channel) or via ALA- UB
- Optical alarm. Is displayed in the LCD and a separate LED dis-
play. Additionally the set rate flashes with AAA.A.
- Staff call via the MFC staff call cable.
The user must check the optical and audible alarm during the
switch-on test. An alarm must be activated to test the staff call
alarm of the Vista basic, e.g. open pump cover during operation.
Pump Unit
The pump head is driven by a stepper motor. Each full step of the
motor is realized by 5 microsteps. The motor is driven by an FET
output stage. The function processor controls the motor with the
MS signal. A slot disc which is mounted on the pump head axle is
scanned by two light barriers (PKS1 and PKS2 signal). Thereby the
control microprocessor monitors the direction of rotation and
speed of the pump head.
The pump head position is also determined with the PKS2 signal.
The motor can therefore be accelerated during the withdrawal
phase. Thus a nearly pulse-free flow is realized in the lower deliv-
ery range (<100 ml/h). The total pump head cycles and running
time are available in the service program under history data.
Vista basic 950971 (5/04)

System Overview
Mechanical Occlusion Pressure:
The Vista basic has a linear peristaltic pump. This pump has 12
slides which are driven by a camshaft.
When the pump coveris closed, the pump tube is squeezed (oc-
clusion) by at least one of the slides, independent of the pump
head position. The complete pump unit is mounted behind the
front panel in the cabinet frame. The hinges and the locking bow
for the pump cover are led through the front panel. The pump cov-
er is automatically closed when the operating unit door is closed.
The slides are pressed against the pump cover by a spring system
in the pump unit. Thereby a delivery pressure is realized and
mechanically limited by the springs.
If the pressure limit is exceeded there is no volume delivery.
The drop sensor activates an alarm. If one of the springs fails,
the spring system will ensure that an unsafe condition cannot
occur (free flow). The two remaining springs ensure an ap-
propriately high occlusion pressure.
Electronic Occlusion: Pressure:
The electronic occlusion sensor is mounted on the output side of
the pump. A spring pressure loaded slide is seated on the infusion
line. An increase of pressure in the infusion line leads to a deflec-
tion of the coil core via the pressure slide. The depth of immersion
is measured inductively. When a preset pressure threshold is
reached the pump drive is switched off, and an alarmis activated.
The electronic occlusion pressure is a single channel circuit. In
case of a failure, the mechanically limited maximum pressure can
be reached.
Motor Switch- Off by Both Processors:
Function processor: MS signal to switch-off the motor drive. -
Control processor: MOTEIN signal to switch-off the drive of the
motor operating voltage.
Computer interface
Vista basic 950971 Rev A (5/04)
The Vista basic is equipped with a computer interface. It can be
connected to the optical interface or via the MFC service plug. To
activate the computer operation please ask for a detailed descrip-
tion from B. Braun.
