Only trained personnel must service the Dialog+, i.e. repair, maintenance, software
installation, firmware update, retrofitting and commissioning of the Dialog+.
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.
Switch off the Dialog+ 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 Dialog+ is opened. The voltages present when electrical power is connected to the
Dialog+ can cause serious injury or death.
Pay attention to ESD information, because electronic components are sensitive to
electrostatic discharges.
High Voltage 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.
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.
Only activate the TSM service program for service activities. It is prohibited to connect
a patient to the Dialog+ and to run a therapy if the TSM service program is activated
in the Dialog+. 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 Dialog+ 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).
During servicing on running machines: prevent chemical burns and scalding of the skin
due to the penetration of disinfectant or hot liquid.
Protective gear should be worn in case of servicing of assumed contaminated
machines.
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.
Dispose spare parts (e.g. boards or batteries) according to local disposal guidelines or
of Spare Parts send back to B. Braun Avitum AG free of charge (see chapter 7).
The system configuration saved on a diskette must be downloaded to an other Dialog+
machine only if:
•
the hardware matches and
•
the identical software version number is present.
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.
