remedy the failure, a restart of the therapy is possible!
6.10.2 Device alarms
Device alarms can‘t be mute. An audible alarm sounds
permanently. Infusion will be stopped (patient safe state).
72
6.10.1 Operating alarms System overview
Following alarms (IFU Page 13) will be displayed as text together with
an optical and audible signal:
•Drip alarm
•Pressure alarm
•Air alarm
•End of Standby time

•KOR Alarm
•Pump door open
•Invalid rate
•Reminder alarm
73
6.10.1 Alarm (pressure alarm)System overview
Pressure inside the infusion system will be measured by a
mechanical pressure sensor system. This system moves a metal core
inside a coil.Graphic pressure alarm principle
A change in inductivity will create an electronic signal which will
be changed in a digital information. During calibration of the
pressure sensor limiting values will be measured and stored.
In infusion mode there is a continuous monitoring and comparison
of rated value and current value. In case of deviation pressure
alarm will be given.
74
6.10.2 Device alarms System overview
Device alarms can‘t be mute. An audible alarm sounds permanently.
Infusion will be stopped (patient safe state).
„Device alarm“ will be displayed in the LCD display. A numeric error code
will also be displayed.
The error code of the Function processor 80c535 will be displayed in the
upper area of the display (7-Segment-Display).
The error code of the Control processor 68HC11 will be displayed in the
lower area of the displays (text area).
For an efficient troubleshooting you need both error codes!

•Summary
•open questions
•Handing out certificates and service seals to the participants
111
Thank you very much for your attention!
112
Peristaltic Pumps
113
The Seal‘s Meaning
•Only use the Seal for B. Braun-Devices
•The Seal number is exceptional for your Personal use (related on
your name) and not transferable
•The Seal number are only allowed to stick on Devices which you
have been trained on (normally by a B|BRAUN certified Technical
Trainer)
•A virgin Seal upon the Device says that after your sealing, there
weren‘s anyone who‘s opened it
114
The Handling of the Seal
•After quitting the job as a Service engineer, please send us
(Technical Training Dept.) an information about it and destroy
your remaining seals
•In the moment you are receiving a new seal number all probably
existing older seal numbers on your name are invalid. Those older
numbers are going to be deleted at B|Braun
•Eventually remaining invalid seals have to be destroyed by
yourself
•If you change your employer, please order a new seal number (We
need your new companies complete address)
•Please order your seals like you order your spare parts (when
ordering, please write your seal number as clear as possible)
