Commissioning and Service
Only trained personnel must service the , i.e. repair, maintenance, software
installation, firmware update, retrofitting and commissioning of the .
Servicing must only be performed with proper tools, calibration equipment and be in
accordance with the most recent revision of this service manual/technical information,
which must be clearly and thoroughly understood.
Prevent Electrical Shock Hazard
Switch off the and disconnect unit from mains if you have to open the
machine for servicing. Do not touch any exposed wiring or conductive surfaces while
the is opened. The voltages present when electrical power is connected to the
can cause serious injury or death.
ESD Information
Pay attention to ESD information, because electronic components are sensitive to
electrostatic discharges.
High Voltage
in TFT Monitor
If a battery option is present in the machine:
High voltage can be present at the backlight inverter board BIB in the TFT monitor,
even if the machine has been disconnected from mains. Pull out the battery
compartment in the base platform and switch off the battery voltage before opening
the machine.
Protective Conductor in TFT Housing
If the TFT housing had to be opened during a service job, the tight seat of the
protective conductors in the TFT housing must be checked.
TSM Service Program
Only activate the TSM service program for service activities. It is prohibited to connect
a patient to the and to run a therapy if the TSM service program is activated
in the . If the TSM service program is activated the complete alarm system is
disabled. The TSM service program is started in the service mode: digital board, service
switch S1, position 2.
Software
The software is installed in the software mode: digital board, service switch S1,
position 3.
Therapy Mode
After completion of all procedures switch back to the therapy mode: digital board,
service switch S1, position 0.
Calibration
Only perform a calibration after the has reached working temperature and the
machine was disinfected and decalcified. Save the calibration data (CFC) before you
exit the TSM service program:
TSM Main Menu, File Operations, Save Calibration Data.
Tubing
Tubing must be replaced only by the same tubing type/length and identical installation
manner.
Make sure that the tubings in the machine are not kinked or twisted after servicing
(e.g. if sub-racks are pulled out and inserted again). The tubing must not touch
moving/rotating components (e.g. motors of gear pumps).
Wiring
Wiring must be replaced only by the same cable type/length and identical installation
manner. The cables must not touch moving/rotating components (e.g. motors of gear
pumps).
Prevent Chemical Burns and Scalding
During servicing on running machines: prevent chemical burns and scalding of the skin
due to the penetration of disinfectant or hot liquid.
Contaminated Machines
Protective gear should be worn in case of servicing of assumed contaminated
machines.
Cover in Rear Door
Servicing of mechanical assembly groups (components in contact with fluid): the cover
for the switch mode power supply microcontroller SMPS-MC in the rear door must be
assembled during servicing because it serves as a spray protection.
O-Rings
Always check o-rings from disassembled groups/components and replace if necessary.
Figures
The displayed figures can differ slightly from the machines on site, due to different
hardware statuses.
Fuses
If fuses are replaced they must exactly match the type and rating specified by the
manufacturer in the spare parts list/technical information. Where applicable: fuses
must be approved by UL/CSA.
Spare Parts
Only use original spare parts manufactured and sold by B. Braun Avitum AG.
Disposal and Taking Back
of Spare Parts
Dispose spare parts (e.g. boards or batteries) according to local disposal guidelines or
send back to B. Braun Avitum AG free of charge (see chapter 7).
System Configuration
The system configuration saved on a diskette must be downloaded to an other
machine only if:
•
the hardware matches and
•
the identical software version number is present.
Function Check
Check the respective function of the assembly group/component after servicing. A
complete function check must be performed after every service, according to the
operating manual.
