Pre-use check
The Servo
…
System demands the user to start the
automatic Pre-use check at every start-up of the
system. It is also possible to select the Pre-use check
via the Standby menu.
Test Test description * Recommended action if the test fails
During system startup Internal technical tests:
•
S/W download
•
S/W check
•
Reading EEPROM
•
Checksum EEPROM
1. Restart the Servo … .
2. Reinstall the system software.
Start Pre-use check
Internal tests Audio test.
(PAN + MON)
Make sure that the Patient Unit front
cover and the User Interface rear cover
are correctly mounted, otherwise these
tests may fail.
Check in the Test log if it is the Panel or
the Monitoring test that have failed
(requires FSS-card):
– If Monitoring test fails: replace
PC1772 Monitoring.
– If Panel test fails: replace
loudspeaker or PC1777 Panel.
Barometer test Checks that the barometric pressure
measured by the internal barometer is
within 630–1080 hPa.
Checks that the measured barometric
pressure values differs less than 8 hPa
between MON and BRE.
(BRE + MON)
Check the Barometric pressure value in
the Status window:
1. If that value is within 630–1080
hPa, replaced the PC 1771 Control.
2. If that value is outside 630–1080
hPa, replaced the PC 1772
Monitoring.
Gas supply pressure
test Checks that the gas supply pressures
(Air and O
2
) measured by the internal
gas supply pressure transducers are
within 2–6.5 kPa x 100 (2.0–6.5 bar).
Checks that the measured supply gas
pressure values differs less than 20
mbar between MON and BRE.
(BRE + MON)
1. Check that the connected gas
supply pressure (Air and O
2
) is
within the specified range.
2. Start the Servo-i in a ventilation
mode and check the alarms:
– If an Air supply pressure-alarm is
activated, replace the Gas
module Air.
– If an O
2
supply pressure-alarm is
activated, replace the Gas
module O
2
.
The Servo … Ventilator System – User's Manual
describes how to perform this Pre-use check. The
Pre-use check-description on the following pages
gives a more detailed information about the Pre-use
check. This information can be used e. g. during
troubleshooting of the Servo … System.
* Text within brackets refers to the tested subsystem; BRE = Breathing, MON = Monitor, PAN = Panel.
