Intended Use This manual is intended for:

– first studies (to acquire a basic knowledge) – reference purposes (for start-up, maintenance and repair)

Organization The manual is divided into 6 chapters:

0 General Information 1 Config.Sys, Service.Sys, CCS Program 2 Repair / Adjustment / Maintenance 3 Circuit Descriptions and Circuit Diagrams 4 Spare Parts Catalog 5 Start-up and TSC

Page Identification Page identification 1-3 is to be interpreted as: Chapter 1, page 3. Qualification This manual is intended to assist service technicians and assumes the following:

– that the user is familiar with the current operating instructions – that he has the necessary background experience in mechanics, electrical

engineering and medical engineering;

– that he has been authorized by the manufacturer to perform maintenance and

repair work;

– that he has access to the necessary auxiliary and measuring equipment.

Limitations This manual is not intended to provide an alternative to instruction courses

offered by the manufacturer.

Manual changes Manual changes will be released as new editions, supplements or product

information. Note:

Any modifications to circuit and component layout diagrams (SP/BP) do not always affect footers (edition). The current state of these diagrams is indicated in the index field of each respective SP/BP. The user/technician can use the respective marking on the printed circuit board to verify whether the SP/BP comply with the actually existing printed circuit board in the machine.

In general, this manual will be subject to modification.

Specification Unless otherwise specified, potentials indicated in circuit diagrams and calibra-

tion instructions are related to the perinent ground. For example, 24 means ground for the 24 V voltage.

Component Example: identification in circuit diagrams

This refers to a resistor with position number 75 and a resistance of 1.2 ohm. The decimal point used to indicate the value is replaced by a unit symbol (to

reduce the possibility of errors). Resistors Capacitors:

R1: 0.1 Ωµ 1: 0.1 µF 1R2: 1.2 Ω 1µ2: 1.2 µF 1K2: 1.2 kΩ 1000µ: 1000µF

Note When repairing blood cell separators and replacing spare parts, observe the

protective ESD measures to be taken to prevent electrostatic discharge (e.g. EN 100015-1).

– Use the inflating bulb to slowly increase the pressure and verify the upper switching point. – The upper switching point has been reached when the pressure field changes from bright to

dimmed.

– Target value: 55 mmHg ±5mmHg (7.3 kPa ±0.6 kPa)

2-62 Fresenius HemoCare COM.TEC 1/04.01 (TM)

● Verification of the lower switching point of the pressure switch

● Verification of the pump’s maximum over-pressure

– Short the SN pressure switch on LP-Z 175 by using a link wire. – Turn cuff pump on. – Verify that the maximum pressure in the pressure cuff does not exceed 120 mmHg (16 kPa). – Remove the link wire from the pressure switch.

● Verification of the inflation time

– Apply the pressure cuff to the arm. – Turn cuff pump on. – The cut-off pressure must have been reached after a maximum of 20 seconds.

2.20.2 Adjustment

– The adjustment is restricted to the upper switching point of the pressure switch. – Connect the reference gauge to the luer lock connector (rear panel). – Clamp the line on the outlet side of the air valve. – Use a syringe to apply just as much pressure for the contact of the switch to change. – The switching point can be adjusted with the stud screw (Allen screw 1.27 mm or. 1/20 inch)

on top of the pressure switch. Adjust the pressure switch to 55 mmHg ±3 mmHg (7.3 kPa ±0.4 kPa).

– Seal the stud screw with lacquer.
