EEPROM is checked during the
start up and during the sensor
test for CRC errors
Take the machine out of use;
Call Service
Recalibrate the complete
system. If that does not solve
the problem exchange the
module 2
Temp Sensor readings
not available
Call Service
AVM3-1
The measured temperature
value is out of tolerance
Restore the function of the
temperature sensor
Recalibrate the temperature
sensor in the service mode. If
that does not solve the problem
exchange the module 2
Temp Sensor out of
tolerance
Check Heating System -
Call Service
AVM3-1
The over-temperature switch
activated or the temperature of
the patient module has not
increased for 20 min even
though heater is switched on
Restore the function of the
heating blanket
Recalibrate the temperature
sensor in the service mode.
Check the correct function of
the solid state relay and the
according power supply
Fan Error
Check Fan - Call Service
AVM3-1
The Fan does not deliver any
impulses
Restore the function of the Fan 1. Check for physical
obstructions
2. Exchange the fan
AC Power lost, using
Battery
AVM3-1
The line power fail signal
reports use of battery
Restore the line supply 1. Ensure the correct line
voltage
2. Ensure the correct function of
the power supply module
Continuous Pressure
AVM3-1 Manual/ spontaneous
Over a time of 10 seconds the
minimum and the maximum
pressure is measured. If the
actual pressure is greater than
10 mbar and the difference
between the minimum and the
maximum pressure is smaller
than 5 mbar, the error message
is issued
Increase the pressure
difference
Battery running low
Use Manual Ventilation
AVM3-1 Battery mode
The valid discharge time is over
Restore the line supply 1. Charge the battery
2. Check the capacity of the
battery, if necessary, exchange
it.
Ambient Air Intake:
Check Fresh Gas setting
AVM3-1 CMV, PCV
In the expiration phase there is
a sub-atmospheric of more than
2 mbar, an error message is
issued
Correct the fresh gas flow.
When the smallest Pressure
zero higher is, the error
message disappears
Check the correct calibration of
the pressure sensors
AVM3-1 Controlled ventilation
• The measured PEEP
value is 5 mbar higher than the
set PEEP over a period of 5
ventilation cycles
1. Ensure the correct function of
the APL valve.
2. check the breathing circuit for
obstructions
Set APL to CMV/SP
position
• The controlled
ventilation is being started
Set APL to VENT (CMV)
position
Check Settings
AVM3-2 CMV
The maximum position of the
Proportional valve has been
reached
Decrease ventilation frequency
