The actual I displayed on the KION Monitor. The battery capacity indication, bargraph with %, is related to actual battery voltage. ”100%” is indicated when trickle charge level is reached (fully charged).

The following applies concerning battery voltage supply:

• Battery voltage supply is used as soon as the AC/DC C voltage (e.g. if the power consumption is too high).

• If the AC/DC C 19 V (e.g. at loss of mains power), a ”Switching to battery” alarm indicates that battery voltage supply is in use.

• First battery alarm ”Limited battery capacity” is activated when battery voltage reaches below 23 V (22 V if an E These voltage levels correspond to ”20%” indicated.

• Second battery alarm ”No battery capacity” is activated 10 minutes after first battery alarm or when battery voltage is below 22 V (21.5 V if an

XTRA INTERNAL BATTERY is connected). These voltage

E levels correspond to ”0 %” indicated.

• All functions will be cut off when battery voltage reaches below 21 V.

Battery capacity indication and alarms are generated via the ALA power supervision function.

Service interval for the I

Filter: The filter protects the system from particles in the

gas delivered to the air inlet. The filter must be replaced during the ”Twelve months maintenance”.

Inspiratory valve temperature sensor: The temperature of the supplied gas is measured by

the inspiratory valve temperature sensor. This sensor is situated in the gas flow.

The output signal from this sensor is used to compensate for the gas density variations due to temperature.

Supply pressure transducer:

The pressure of the supplied gas is measured by the supply pressure transducer.

The output signal from this transducer is amplified. It is then used to calculate the absolute pressure of the gas to compensate for gas density variations due to pressure.

Delta pressure transducer and net: The gas flows through a net (resistance) which

causes a pressure drop. The pressure is measured on both sides of this net and the differential pressure value is then amplified.

Nozzle unit: The nozzle unit contains a valve diaphragm. The valve

diaphragm, controlled by the inspiratory solenoid, regulates the gas flow through the G

AS MODULE.

Metal nozzle units (Type I) modified for backpressure must be used together with a small washer that is placed on top of the inspiratory solenoid. This washer will support the diaphragm and distributes the backpressure over a larger area on the diaphragm. This function is integrated in the plastic nozzle units (Type II) and the small washer is not used in these

AS MODULES.

G The nozzle units are provided with a mechanical key

to prevent that the nozzle unit is mounted into wrong

G An O-ring and the valve diaphragm (Type I) or the

complete plastic nozzle unit (Type II) must be replaced during the ”Twelve months maintenance”. After replacement, allow the diaphragm to settle during approx. 10 minutes before gas pressure is connected to the G

AS MODULE.

Inspiratory solenoid: The gas flow through the G

AS MODULE is regulated by

the inspiratory solenoid via the nozzle unit. The current supplied to the solenoid is regulated so

that the gas module will deliver a gas flow according to the front panel settings.

CONTAINER and the INSPIRATORY FRESH GAS VALVE.

• SV4 is a magnetic valve preset to open at 14 kPa (140 mbar). Protects the patient from high pressure in the fresh gas.

• SV8 is a magnetic valve preset to open at -3.5 kPa (-35 mbar). Protects the pressure transducers from negative pressures created during use of closed suction catheter systems.

The magnetic valves (SV2 – SV4 and SV 8) contain a permanent magnet that affects the metal valve cone. The distance between the magnet and the valve cone is preset to open the valve when the pressure limit is reached.

Do not cover the visable hole in the center of valves SV2 – SV4. If this hole is covered, the valve will not open.

from the block INSTANT O2 SUPPLY is connected to

the fresh gas channel in the I

NSPIRATORY GAS BLOCK.

Inspiratory fresh gas flow transducer: The gas flows through the flow transducer in two

parallel channels, one large main channel and one small measuring channel. The main channel is fitted with a wire mesh net, the resistance of which causes a certain proportion of the gas to flow through the measuring channel. The flow through and the differential pressure across the measuring channel acts on a small metal disc (”flag”) which, via a metal pin, presses on a small semiconductor strain gauge.

This strain gauge consists of diffused resistors on both sides of an elastic silicone rod. The resistors are connected as a part of a Wheatstone bridge, the other part of which is situated on PC 1797/PC 1748

RESH GAS FLOW. The more flow in the channel, the

F higher the pressure on the strain gauge. The change in resistance in the Wheatstone bridge is converted to a corresponding signal voltage.

Cleaning of the flow transducer is described in chapter ”Routine cleaning” in the Operating Manual.

Inspiratory Fresh Gas Valve with PC 1751 Step Motor:

NSPIRATORY FRESH GAS VALVE is operated by a step

The I motor with a special shape slotted cam mounted on the motor shaft.

The gas flows through the fresh gas valve tube (silicone rubber) that is a part of the inspiratory fresh gas channel. The gas flow through the valve tube is then regulated by a movable lever arm that squeezes the valve tube against a fixed arm. This movable arm is attached to the cam and transfers the step motors rotation to a controlled opening position of the valve tube.

The change in flow through the valve tube is microstep controlled by the step motor. The step motor is controlled by PC 1751 that is a part of the step motor

assembly. PC 175 1 S

two photo detectors. When the step motor reaches either end position of the cam slot, the light beam between the LED and the corresponding photo detector is interrupted by a cam screen. The cam screen is a part of the slotted cam mounted on the motor shaft. This will generate an end position signal from PC 1751.

The position of the LEDs / detectors in relation to the cam screen is very important. If a LED / detector gets out of position, or if they fail, this will cause the step motor to ”rattle” because end positions are not properly indicated.

When power supply to the I VALVE is switched off (or if the power supply fails), the step motor will always end up with the inspiratory valve in fully opened position.

The fresh gas valve tube must be replaced during the ”Six months maintenance” and the ”Twelve months maintenance”.

The expiratory gas flow is regulated by the PEEP VALVE. This valve also regulates PEEP pressure if set on the C

The PEEP V magnet acting on a lever arm which squeezes the expiratory valve tube (silicone rubber) against a fixed arm. The more the magnet is activated, the more the valve will move towards the closing position.

When power supply to the magnet is switched off, the valve will be fully opened because of the spring. This ensures that the patient always can exhale through the ventilator at a power failure.

The PEEP valve is controlled by CON. At a PEEP setting, information from the PEEP pressure transducer is used to regulate the valve position during expiration.

The PEEP valve tube must be replaced during the ”Six months maintenance” and the ”Twelve months maintenance”.

• Timing: Output Insp. time and Exp. time signals are generated. These are used by MEA to control zeroing of the flow transducers.

• Fresh gas outlet: Input signal from the Hall sensor in the A valve is opened. This signal is used to light up a LED on the C

• Pressure alarm: Input signal from MEA indicating that upper pressure limit is reached. Used to stop inspiration time and immediately start expiration time. This will open the PEEP V other valves in safe positions.
