							In operating level C the automatic
mobile unit recognition system (AWK)
allocates programme places from 1 -
15 to mobile units with the correct
coding.
The unit coding (on the mobile unit) and
the programme place with the
corresponding programme (in the
electronic control unit) have to match
each other.
To do this:
Each mobile unit must be coded
before being used for the first time
(see "Coding the mobile unit"), and
The programme for which the mobile
unit is coded must be allocated to the
correct programme place.
See "System function - Selector switch
organisation" in the Programming
manual for information on how to
change programme positions.
Before starting a programme it is
absolutely essentialthat you check
that the programme shown in the
display is the correct one for the
mobile unit being used.
Otherwise inadequate cleaning or
disinfection could be the result.
Please make sure, that the places
assigned for the programmes using
Automatic mobile unit recognition
are not changed around arbitrarily.
Automatic mobile unit recognition (Optional)

							Mobile unit coding
The automatic mobile unit recognition
feature assigns a programme place to
a mobile unit. The mobile units must be
coded with a magnetic strip (via a Bit
combination).
In operating level C, the only
programme available for a coded
mobile unit is the one assigned to the
corresponding programme place.
After a coded mobile unit has been put
into the machine and the door closed,
the automatic mobile unit recognition
system will select the allocated
programme.
Make sure that there are no
small metallic objects or instrument
parts attracted to the magnetic strip,
in particular to the underside of it.
Any metallic objects on the strip can
result in the coding being incorrectly
read.
Pressto start the programme.Coding is effected through 5 Bits:
–Bits 1 to 4 define the mobile unit
code,
– Bit 5 serves as a control (Parity Bit).
Bit 6 controls the volume of inflowing
water and the circulation pump for
mobile units with side coupling (WAK).
Its settings cannot be altered.
Mobile units without side coupling are
coded with tracks which do not contain
Bit 6.
Automatic mobile unit recognition (Optional)
17 
						

							Mobile unit coding strip
15 different codes can be set. They are
assigned to programme places 1 to 15.
Under "System function, Selector switch
organisation" the matching
programmes have to be put into the
first 15 programme places.

The coded total must be an even
number.
The settings on Bit 6 (WAK) are not
included in this calculation.
If the coded total gives an odd number,
the message CHECK MOBILE UNIT
RECOGNITION appears.
If the mobile unit code equals 0, the
message NO MOBILE UNIT
RECOGNITION appears. In neither
case can the programme be started,
The mobile unit recognition function
must be re-set.Setting mobile unit coding
To set or alter the coding of a mobile
unit with automatic recognition (AWK),
proceed as follows:
Unscrew the track with AWK (using
an allen key) and remove from the
retainer.

Remove the magnetic strip from the
track.
Automatic mobile unit recognition (Optional)
18 
						

							Set the programme place coding.

Put the magnetic strip back in the
track.
The magnetic strip must be placed
in the track such that the Bit coding
set out in the chart is visible through
the round windows in the track.Place the track in the holder in the
mobile unit and screw firmly in place.
Bit 6 (WAK) is not a component part
of the modifiable magnetic strip.
Make sure that you code mobile
units with side connection with a
track where Bit 6 is set to I.
Mobile units without side coupling
must be coded with a track without
Bit 6.
The magnetic strips on G 7823 /
G 7824 / G 7825 / G 7826 must have
greymagnets.
The magnetic strips on G 7827 /
G 7828 must haveblackmagnets.

							This washer-disinfector can be fitted
with a variety of mobile units, which can
be equipped with a variety of modules
and inserts depending on the type and
shape of items requiring cleaning and
disinfection.
Select mobile units, modules and
inserts which are appropriate for the
application.
Notes on the individual areas of
application and examples of loading
are given on the following pages.
Before starting a programme you
should carry out a visual check on
the following:
– Is everything correctly
loaded/connected for cleaning?
– Are the spray arms clean and do
they rotate freely?
–
Are the filters clean? Remove any
coarse soiling and clean them
properly if necessary.
–
Is the adapter connecting the water
supply to the spray arms/jets
correctly connected?
–
Are all chemical containers
sufficiently filled?At the end of each programme:
–Carry out a visual check of the load
for cleanliness.
–Check that all hollow shafted
instruments are still securely located
on their jets.
Any hollow instruments that have
become disconnected from their
adapters during processing must be
re-processed.
–Check that the lumen of hollow
instruments are free of obstruction.
– Check that jets and connectors are
securely held in position in the
baskets or inserts.
Protein test
Cleaning results should be subjected to
periodicprotein tests, e.g. with the
Miele test kit.
