Should one chooses to enter the Pressure Sensor Setup routine there are two options:
•
Pressing any of the four control knobs will use the factory default value as shown.
•
Pressing the RUN / IPPV button will use the actual current measured value, which is
constantly being updated on the screen.
The chosen value is stored in the non-volatile memory and will remain unchanged until the
Pressure Sensor Setup routine is run again.
Use the Pressure Sensor setup routine if there is piston movement when no patient is
attached the wye piece is not capped AND you have flushed the sensing line.
The initialisation procedure continues into the Auxiliary Controller Boot Up Sequence.
Auxiliary Controller Boot Up Sequence
After the option for pressure sensor setup, the following sequence occurs:
INITIALISING DRIVE CONTROL
At this stage the servomotor drive, the ViX Drive, is presumed un-initialised and its
initialisation begins. The software version is displayed at the bottom left hand corner of the
screen. The 24 volt supply line feeding the motor drive as well as the individual battery
voltages are measured and its value displayed on the screen e.g.
CHECKING DRIVE VOLTAGE:
27.9 14.0 13.9
If the supply voltage, 27.9 above, is less than 16.0 volts, then the shutdown procedure starts
as there is insufficient battery power to safely run the system. In this instance you should
connect the mains power and re-start the system.
If the voltages are sufficient one beep is heard as the screen displays the following.
VOLTAGES ALL OK
APPLYING POWER TO VIX DRIVE:
The power to the servomotor drive is applied and tested. Then after successful
communications have been established with the ViX drive, two beeps are heard and the
following is displayed.
SETTING COMMUNICATIONS TO DRIVE
SETTING COMS RATE TO 19200
COMMS - SET AT 19200 BAUD - OK
The servomotor drive is then initialised. The next stage checks the Motor Drive Integrity as
the following is displayed
NOW TESTING VIX DRIVE INTEGRITY
Assuming all is well then the message
INITIAL DRIVE CHECK OK
is displayed, followed by a string of ones and zeros on the screen. if at any time during this
Auxiliary initialisation procedure an error is detected then an error message is displayed and
the whole system shuts down. If everything is as it should be then the screen shows
INITIALISATION COMPLETE
At this stage the Auxiliary Screen looks like the screen below.
