INTRODUCTION
INTRODUCTION
This chapter gives an overview of the PV 101+ and PV 102+ devices and the service
manual.
WARNING!
This product must be:
• subjected to regular service, maintenance and control and any applicable upgrades,
in accordance with BREAS service instructions;
• repaired and/or modified in accordance with BREAS service manuals, technical bulletins and any special service instructions, by service technicians that have been
authorised after BREAS PV 101+/PV 102+ service training, or have an equivalent

1.1
About the PV 101+ and PV 102+
The PV 101+ and PV 102+ are intended for use in homes, while travelling or in institutions. They are bi-level devices, which means that the expiration pressure (EPAP) can
be set lower than the inspiration pressure (IPAP).
1.1.1
Intended use of the PV 101+
The BREAS PV 101+ device is intended for treatment of obstructive sleep apnoea.
1.1.2
Intended use of the PV 102+
The BREAS PV 102+ device is intended for treatment of obstructive and central sleep
apnoea, hypopnea and other forms of sleep-related breathing problems. The back-up
rate is adjustable, as well as the rise time, which makes it possible to customise the time
for the pressure to change from EPAP to IPAP.
1.1.3
Design and function
The PV 101+ and PV 102+ are based on a blower which is driven by an electronically
controlled servomotor. The microprocessor-based electronics calculates, from the set
pressure, rate, rise time etc., the correct motor speed. The set pressure and trigger sensitivity is continuously monitored.
An audible alarm is immediately given in the event of a power failure.
1.1.4
Service personnel’s training requirements
Service personnel working with the PV 101+ and PV 102+ devices should have medical/technical training and a good knowledge of the construction and function of respiratory devices. Authorisation by BREAS PV 101+/PV 102+ service training is
recommended.
Always contact your BREAS representative if you have any questions or if
training is required.

Circuit board descriptions
This section contains detailed descriptions and figures of the PV 101+/PV 102+’s circuit
boards.
7.4.1
CPU board
All the push-buttons are mounted on the CPU board together with the LEDs and the
three bar-graphs for pressure display. Also mounted here is the four 7-segment displays
for the rise time and backup rate displays (PV 102+).
The microprocessor with its software is also located here, as well as an internal memory
(DALLAS) for the logging and storage of the patient usage data.
Refer also to the circuit diagrams (See section 7.6.1, 7.6.2, 7.6.3, 7.6.4 and 7.6.5) and
component location drawings (See section 7.7.1).
7.4.2
Power board
The power supply unit is fed primarily with mains power via the mains power inlet to the
internal AC/DC converter. Secondly, the power board can be fed with 12–24 DC via the
external battery input.
Refer also to the circuit diagrams (See section 7.6.6 and 7.6.7) and component location
drawings (See section 7.7.2 and 7.7.3).
The power supply has mains power as soon as the power cord is connected.

Pressure
sensor
The MDA (motor drive assembly) board comprises the driver stage for the blower motor,
the pressure sensor, the flow sensor, the hour counter and the D-shell connector for
serial communication.
The driver stage is built around the U205 control circuit and the Q205–Q210 transistors.
The P21 buzzer is powered by the C221 supercap if the mains power supply should fail.
The pressure sensor, which is of the semi-conductor type, is amplified by U201. The offset and gain can be adjusted using the P200 and P201 potentiometers. The signal is
used for regulating the pressure.
The flow sensor is also of the semi-conductor type, a mass flow meter. The flow that
passes the sensor is proportional to the flow through the flow resistance in the air tube
from the blower. The offset and gain can be adjusted using the P202 and P203 trim
potentiometers. The signal is used for initiating the trigger and the mask-off function.
Refer also to the circuit diagrams (See section 7.6.8, 7.6.9 and 7.6.10) and component
location drawings (See section 7.7.4).

Electrical safety measurements
Electrical safety measurements must be made in accordance with EN 60 601-1. However, you can make an insulation resistance measurement instead of the voltage test
specified by the standard. The measurements can be made using an automatic electrical safety tester. All tests must be performed in accordance with class II type BF.
Supply voltage
•
Note the power voltage reading.
The voltage must be noted for each service check, as the currents measured are
directly in relation to the supply voltage. This allows all measurements made on the
same machine to be compared with measurements made on different occasions.
Insulation
•
Measure the insulation resistance using a 500V DC power supply.
The most suitable method is to connect the plus lead to the two ventilator power socket
pins and the minus lead to the casing or patient air connector.
The measurements made during the delivery inspection can be used as reference values for measurements made during future services. If no reference values are available,
the value for the insulation resistance should be >20MΩ.
Leakage currents
•
Measure the leakage currents at different parts of the ventilator using an RC circuit
to ground.
The measurements are made partly at normal case (NC) and at the single fault condition (SFC). Reverse the polarity of the power supply and note the highest value.
The leakage currents to ground must not exceed the stated limit values.
Leakage currents from the casings
•
Measure the leakage current of the casing at an unpainted point, for example, the
head of a screw.
Limit values:
NC
SFC
Break neutral for SFC.
< 0.1mA
< 0.5mA
Patient leakage currents
•
Measure the patient leakage currents between the patient connector and ground.
Limit values:
NC
SFC
Break neutral for SFC.
< 0.1mA
< 0.5mA
Leakage currents with mains power supply at the patient connected part
•
Perform this test using an automatic electrical safety tester with this function.
See the safety instructions for the tester.
Limit value:
7–8
SFC
< 5mA
