Troubleshooting the Fabius Tiro should always begin by communicating with
those who observed or experienced a problem with the unit. This may eliminate unnecessary troubleshooting steps. Once a general problem is identified, refer to the flow charts in the Troubleshooting Section to determine the
proper corrective action to be taken.
After any component is replaced, verify that the unit is operating properly by
running the appropriate diagnostic procedure. The PMS PROCEDURE must
also be performed after any component is replaced.

Fabius Tiro Function Description
3 Battery Backup Fabius Tiro backup power is provided by two series-connected 12 V
rechargeable batteries. These batteries remain on charge as long as the
machine is plugged into an active AC outlet. Should power to the main controller PCB assembly fail while the machine is in operation, the batteries will
allow the machine to continue operating for a minimum of 45 minutes, provided the batteries are fully charged.
The batteries are located within the controller housing and are accessible by
opening the ventilator compartment. The 3.15A battery fuse is located on the
power entry panel at the back of the machine.

5 Function Descrip-
tion of Gas Box
The supply gases flow through the filters and non-return valves in the gas
inlet assembly. Pipeline supply pressures are indicated on gauges located on
the flowmeter assembly. Cylinder pressure gauges are located on the base
machine assembly. The pressures of O2 and N2O delivered to the flowmeter
assembly are set by regulators on the gas inlet assembly.
Should the O2 supply fail or its pressure decrease below a certain limit, the
O2 supply pressure alarm switch signals an alarm.
Figure 10 Gas Box Functional Diagram (Part 1 of 2)
If the O2 flush button is pressed, oxygen is delivered to the fresh gas outlet.
The fresh-gas ejector prevents the fresh gas from flowing back into the anesthetic vaporizer. This avoids an increase in the anesthetic gas concentration.

6 SORC (Sensitive
Oxygen Ratio Controller)
20
Dräger Medical AG & Co. KGaA 6020.002 Revision B Released
The SORC is a control element that functions like an N2O shut-off device and
ensures a vital O2 concentration in the fresh gas. In the event of an O2 shortage, the SORC limits the N2O flow such that the O2 concentration in the
fresh gas does not decrease below 23 vol.%.
If the O2 flow control valve is closed or if the O2 flow is lower than or equal to
200 mL/min, the SORC interrupts the N2O flow.
N2O can be added when the O2 flow is approx. 300 mL/min. In this case, the
SORC also prevents O2 concentrations below 23 vol.%.
The SORC bypass allows O2 to bypass the restrictor in the SORC when O2
flows above 10 L/min. are needed.

RETURN TO CD-ROM TABLE OF CONTENTS
Function Description Fabius Tiro
Figure 12 SORC Functional Diagram (Part 1 of 2)
The flow control valves are used to adjust the O2 and N2O flows.
Restrictors located at the outlets of the SORC generate back-pressures.
These back-pressures exert a force on the control diaphragms of the SORC.
The O2 back-pressure opens the SORC. The N2O back-pressure closes the
SORC. The pressure ratio at the control diaphragm affects the N2O flow.
The restrictors and the spring tension are dimensioned such that a minimum
concentration of 23 vol.% O2 is always ensured. The maximum O2 flow is
approx. 12 L/min.

7 Compact Breathing
System, Cosy II
Figure 13SORC Functional Diagram (Part 2 of 2)
The Cosy II compact breathing system allows various modes of patient ventilation: manual and spontaneous breathing, volume controlled, and pressure
controlled.
In the "MAN" position, the compact breathing system is closed to atmosphere. This position is used for manual ventilation of the patient. The APL
valve opening pressure can be adjusted from 5 to 70 cmH2O.
In the "SPONT" position the APL valve is open to atmosphere. This position
is used for spontaneous patient breathing.
The pressure limit (Pmax) can also be adjusted (through front panel interface)
during volume control from 15 cmH2O to 70 cmH2O using the control box
and the PEEP/Pmax valve.
