– O2 Diaphragm PCB
– Fan
Power supply unit The power supply unit delivers the supply voltages for the device. The input
voltage range is 100 V to 240 V AC and 50 Hz to 60 Hz. The power supply
unit can also be operated with an external rechargeable battery (12 V or
24 V).
The connection to the alternating voltage is made by a power cable. The connection for the external rechargeable battery is made by an encoded connector.
The power supply unit actuates the „Mains power“, „External battery or onboard power supply“ and „Internal battery“ LEDs. The LEDs are mounted on
the membrane keypad of the control panel and indicate the respective operating status.
The device includes two internal rechargeable batteries (2 x 12 V) which
enable uninterrupted operation in the event of a mains power failure. The
internal rechargeable batteries supply the O2 sensors with power even when
the device is switched off. When the device is switched on the valid O2 values are present.
The power supply unit generates the following supply voltages:
–+5 V
–-15 V
–+15 V
–+24 V
–+48 V
The output voltages are short-circuit-proof and stable at no-load.

Temperature hybrid
The temperature hybrid reads the data of the AWT01 sensor and converts
these into digital signals. An electrical isolation occurs in this process.
Internal temperature measurement
The internal temperature measurement is a safety function. In the event of
overheating (if the internal temperature of the device is too high), an alarm is
sounded.
Fan actuation and fans
The fan rotates quickly after the device has been switched on to remove any
residual oxygen from the device. The rotation of the fan is detected and controlled in three stages (slow, medium and fast).
Three temperature sensors control the fan.
CAN
The CAN interface is a fast, serial interface. Via the CAN interface the control
unit can communicate with the electronic and pneumatic assemblies. The
transmission rate is 800 kbit/s.
Motor actuator The motor actuator controls the blower motor. The motor actuator is located
in a self-contained housing. The supply voltage for the motor actuator is +48
V and is protected by a fuse (6.3AT).
The input voltage range of the motor actuator is 12 to 52.5 V. The rotation
speed is set by the Central Control Board. The control voltage for the rotation
speed is 0 V to +5.00 V, corresponding to a rotation speed of 0 to 12,000 rpm.
The rotation speed range is 4,000 to 12,000 rpm.
The motor actuator acquires the „actual speed signal“ and forwards it to the
Central Control Board. The „actual value signal“ is 6 pulses per rotation. In
the event of discrepancies in the rotation speed the Central Control Board
adjusts the speed according to the deviation.

O2 Valve PCB The O2 Valve PCB holds the pressure sensors (absolute pressure S6 and S7
and O2 supply pressure S5), the actuator for the O2 calibrating valve and the
nebulizer valve and the actuator for the valve block.
The signals of the pressure sensors are amplified and routed to the Central
Control Board. The supply voltage (+5 V) for the pressure sensors is generated by the O2 Valve PCB.
The valve block valves, the O2 calibrating valve and the nebulizer valve can
be operated separately by an electronic switch. They are actuated by the
Central Control Board.
Fig. 4 Block diagram of the O2 Valve PCB
O2 Diaphragm PCB The O2 Diaphragm PCB amplifies the signals from the O2 sensors and mea-
sures the temperature of the O2 sensors and of the respiratory gas in the
inspiration block. The temperature of the O2 sensors is required to compensate for the temperature-sensitive O2 measurements. The EEPROM on the
Central Control Board stores the calibration data of the sensors. The reference voltage for the O2 sensors is generated from the voltage of the
rechargeable batteries.
The supply voltages for the O2 Diaphragm PCB are +5 V and +15 V.

Touch-panel Analog-resistive touch-screen
Function descriptions
Control panel with TFT colour display
Fig. 8 Analog-resistive touch-screen
Analog systems consist of two opposing conductive indium tin oxide (ITO)
layers (x and y layer) which are actuated with a constant direct voltage.
Indium tin oxide is a transparent semiconducting material.
Between the two ITO layers there are a large number of small, barely visible
so-called spacer dots which ensure the two layers are kept separate.
In 8-wire systems the touch-screen has eight wires routed to the controller –
four for each axis.
When the touch-screen is touched at a certain point where the two ITO layers
are located an electrical contact is produced. The resistance of this contact
results in a different voltage at each point. The change in voltage is then used
to define the x and y coordinates.
The Central Control Board controls the communication between the processor system and the touch-screen. The correct position is determined with the
aid of the relevant software drivers. The analog touch-screen works very precisely, and provides a high resolution.

Device functions
Ventilation function When the device is switched on the power supply unit supplies the blower
motor with operating voltage. The blower motor draws in ambient air through
the microfilter F1, the volume and the sound insulators SD1 and SD3. The
blower motor compresses the gas intake to an overpressure up to max. 140
mbar at a delivery rate of up to 180 L/min. The air compressed by the blower
motor passes through the sound insulator SD4, the cooler, the sound insulator SD2, the filter F4 and the inspiratory flow sensor S1 to the inspiratory nonreturn valve D4. The controller operates the blower motor during a breath at a
constant speed. The bypass valve regulates the inspiratory pressure. The
combination of the blower motor and bypass valve V1 provides a pressure
source.
Fig. 10 Detail view of functional diagram; ventilation function
The sound insulators SD1 and SD2 on the inlet and outlet sides of the blower
motor reduce the sound level.
The bypass valve V1 is operated such that the desired respiratory pressure is
applied to the blower outlet, and thus to the patient. If the patient needs a high
flow during the inspiratory phase, the gas flows in part or in its entirety from
the blower motor outlet to the patient and the gas flow through the bypass
valve V1 is reduced. During the expiratory phase all the blower gas flows
through the bypass valve V1.
The cooler reduces the respiratory gas temperature down to a permissible
range.

O2 mixture with O2 high
pressure
In order to be able to ventilate with an increased O2 concentration, the unit
must be supplied with 2.7 to 6.0 bar O2. The oxygen is filtered by the filter F2.
With the aid of the digital valve block consisting of 8 digital solenoid valves,
oxygen is metered into the volume (mixing chamber). The amount of metered
oxygen depends on the pre-set O2 concentration and on the inspiratory flow
rate measured by the flow sensor S1. The oxygen is metered in a closed control loop. In the process, the inspiratory O2 concentration is measured by the
O2 sensor S 3.1.

O2 mixture with O2 low
pressure („LPO“ option)
NOTE
Connect only O2 low pressure sources without humidifier to the device!
An O2 low pressure source without humidifier feeds the oxygen into the
“LPO” connection on the back of the unit. The filter (filter element) F5 protects
the non-return valve D6 from coarse particles. The oxygen flows from the
non-return valve D6 into the volume (mixing chamber). In the volume (mixing
chamber) it is mixed with the drawn-in and filtered fresh air.
Fig. 12 Detail view of functional diagram; O2 mixture with O2 low pressure
When no O2 low pressure source is connected to the unit, the non-return
valve D6 prevents gas from escaping during normal operation.
NOTE
In „LPO“ mode, the valve block in the O2 supply is not actuated.

Pneumatic assembly
Pneumatic safety devices The pneumatic safety valve D1 ensures that the ventilation pressure cannot
rise above 120 mbar. In the event of inspiratory stenosis the pressure is limited by opening the expiratory valve. The mechanical vacuum valve D2
ensures (except in the case of inspiratory stenosis) that the patient can
breathe ambient air in case of a fault.
The pneumatic emergency vent valve V9 relieves the pressure in the breathing system in a case of expiratory stenosis if the pressure cannot be relieved
through the expiratory valve. To do so, the electric emergency vent valve
(pilot valve) V8 actuates the emergency vent valve V9 accordingly.
Fig. 13 Detail view of functional diagram; pneumatic safety devices
Drug nebulizer The drug nebulizer is operated with 100% oxygen. The pressure regulator
DR1 ensures in the case of widely varying supply pressure (2.7 to 6.0 bar)
that the pneumatic drug nebulizer receives a constant supply pressure of
2 bar.During the nebulizing phase the solenoid valve V5 operates in an “inspiration” (open position) and “expiration” (closed position) cycle. When the nebulizer function is inactive the nebulizer switching valve V5 is closed.

O2 calibration function During operation, the switching valve (oxygen compensation) V4 is set to
“measurement” – that is, the connection between the inspiratory side and the
oxygen sensor is open. During oxygen sensor calibration oxygen passes to
the oxygen sensor. This layout permits “online” calibration of the oxygen sensor S3.1 during ventilation. The oxygen sensor S3.2 must be calibrated manually (patient disconnected).

Flow sensor S1 measures the inspiratory gas flow. The measurement variable is used to calculate the necessary oxygen flow and to actuate the oxygen metering valves V7.1 to V7.8 in order to control the breaths and monitor
the device functions. The flow sensor includes a temperature measurement
function to measure the inspiratory gas temperature.
Fig. 19 Detail view of functional diagram; flow sensor
The flow sensor S2 measures the gas flow through the expiratory valve. The
flow sensor is a temperature-compensated hot-wire anemometer with no flow
direction detector. With this signal the patient is monitored (e.g. the minute
volume).
