Automatic mobile unit recognition (AWK)

In operating level C the AWK attributes a fixed program place to a mobile unit with valid coding.

Program places 1-15 are reserved for the AWK automatic mobile unit recognition.

The unit coding (on the mobile unit) and the program place with the corresponding program (in the

"Profitronic" electronic control unit) must match.

^ Each mobile unit must be coded before being used for the first time.

See "Mobile unit coding".

^ The wash program through which the mobile unit is coded has to be assigned to the relevant program place.

Program place changes, see the

"System function - Selector switch organization" section in the

Programming Manual.

Mobile unit coding

The automatic mobile unit recognition feature assigns a program 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 program available for a coded mobile unit is the one assigned to the corresponding program place.

When a coded mobile unit is inserted in the machine and the door closes, the automatic mobile unit recognition selects the assigned program. Be sure no small items connect to the magnetic strip.

^ Press 6 to start the program.

Important!

Before starting the program with the

"Start" button

6, check that the program needed for this mobile unit is displayed.

Otherwise insufficient wash results may occur!

Always check that programs for mobile units with AWK (on fixed program places) are not exchanged.

The coding is made up of 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 water intake and the circulation pump for mobile units with side coupling. This setting cannot be changed!

Mobile units without side coupling are coded with tracks which do not contain

Bit 6!

16

Automatic mobile unit recognition (AWK)

Mobile unit coding strip

15 different codes can be set. They are assigned to program places 1 to 15.

Under "System function - Selector switch organization" the matching programs have to be put into the first

15 program places.

Setting mobile unit coding

To set or alter the coding of a mobile unit with automatic recognition (AWK) proceed as follows:

The labwasher can be fitted with a variety of mobile units, baskets and inserts, depending on the cleaning application desired.

Application

Check before cleaning

– Are the items to clean correctly sorted, loaded and connected?

– Are the spray arms clean and can they rotate freely?

– Is the filter combination free of coarse soiling? Clean if necessary.

– Is the adapter to the water inlet in place? The spray arms correctly connected?

– Are the detergent and neutralizer containers full?

Check after cleaning

– Check the cleaning results visually.

– Are the jets and connections securely connected with the mobile unit / inserts?

Process validation

As a rule, it is the responsibility of the user to ensure that items cleaned in the machine meet the required standards.

Protein detection

The cleaning result should be checked randomly with an analytic protein inspection, e.g. use the Miele test kit.

19

Application

Loading tips

Select mobile units, baskets and inserts appropriate for the application.

– Always load items in a way that all surfaces are exposed. This ensures that the items will be properly cleaned.

– Do not nest any items inside other items. Keep each item separate.

– Hollow vessels must be arranged for complete inside exposure to the cleaning water.

– Prior to loading the machine or connecting to the machine ensure that vessels with long, narrow cavities they can be completely flushed.

– Hollow vessels such as beakers, measuring cylinders, flasks, etc.

should be inverted and placed in the correct inserts so that water can flow in and out unrestricted. A cover net can be used to reduce the risk of movement during the wash process.

– Use a cover net (e.g. an A 6) or mesh tray to secure small and/or lightweight items to prevent them from blocking the spray arms or being caught in the magnetic strip on the automatic mobile unit recognition system.

– Deep based items should be placed at an angle to allow water to run off easily.

– Tall, narrow pieces should be placed in the center of the baskets. This ensures good water coverage.

– Mobile units with an adapter must engage correctly.

– Engage inserts correctly into the module carts.

– The spray arms must not be blocked by tall items or items which hang down in their path. If necessary, manually rotate the arms to test.

– Petri dishes and the similar should be placed in the correct insert with the soiled side facing the center.

– Insert pipettes with the pointed end downwards.

– Quarter inserts should be placed as close to the middle of the unit as possible.

– Glassware should not stick out of the door area.

,

Ensure that no acid or solvent residues, especially hydrochloric acid or chlorides, get inside the machine.

Effects of Processing Chemicals

General information

Effects Action

Damage to elastomer (seals and hoses) or plastic components of the lab washer may cause the materials to swell, shrink, harden or become brittle, possibly causing cracks to form in the materials. This will impair their function, which will generally lead to leaks.

– Find and correct the causes of the damage.

See "Connected processing chemicals", "Soiling" and "Reactions between processing chemicals and soils" for more information.

Strong foaming during the program prevents proper cleaning and rinsing of the load. Foam escaping from the wash compartment can result in damage to the lab washer.

If foaming occurs, the cleaning process is not standardized and not validated.

– Find and correct the cause of the foaming.

– The process must be checked regularly in order to detect any foaming.

See "Connected processing chemicals", "Soiling" and "Reactions between processing chemicals and soils" for more information..

Stainless steel corrosion in the wash compartment and/or accessories may appear in various ways:

– rust formation (red spots / stains),

– black spots / stains,

– white spots / stains (smooth surface is slightly corroded).

Corrosion that forms holes can result in leaks in the lab washer. Depending on the application, the corrosion may impair the cleaning and rinsing results

(laboratory analysis) or cause corrosion of the load (stainless steel).

– Find and correct the cause of the corrosion.

See "Connected processing chemicals", "Soiling" and "Reactions between processing chemicals and soils" for more information.

27

Effects of Processing Chemicals

Connected processing chemicals

Effects

The ingredients of the processing chemicals have a considerable effect on the durability and functionality (feed performance) of the metering systems.

The metering systems (feed hoses and pump) are designed for a specific type of processing chemicals.

General categories:

– alkaline to neutral pH products,

– acid to neutral pH products,

– hydrogen peroxide.

Action

– Use only those processing chemicals recommended by Miele.

– Perform regular visual inspections of the metering system.

– Regularly check the feed performance of the metering system.

The processing chemicals can damage the elastomer and plastic components of the lab washer and its accessories.

– 176 °F (80 °C) for products containing active chlorine.

The following processing chemicals can release large quantities of oxygen:

– hydrogen peroxide,

– peracetic acid.

– Use only tested processes such as

OXIVARIO or OXIVARIO PLUS

(if available).

– In the case of hydrogen peroxide, the washing temperature should be below 158 °F (70 °C).

– Consult Miele.

28

Effects of Processing Chemicals

Connected processing chemicals

Effects

The following processing chemicals can result in excessive foaming:

– cleaning and rinsing agents that contain tensides,

– emulsifiers.

The foaming can occur:

– in the program block in which the processing chemical is added,

– in the subsequent program block due to carry-over,

– in the case of rinsing agents, in the subsequent program due to carry-over.

Action

– The process parameters of the wash program, e.g. metering temperature, metering concentration, etc. must be set so that the overall process creates little or no foam.

– Observe the instructions of the manufacturer of the processing chemicals.

Antifoaming agents, particularly silicone-based antifoaming agents, can cause the following:

– deposits in the wash compartment,

– deposits on the wash load,

– damage to the elastomer and plastic components of the lab washer,

– attack certain plastics (e.g.

polycarbonates, plexiglass, etc.) in the wash load.

– Use antifoaming agents only in exceptional cases or when they are absolutely necessary for the process.

– Periodic cleaning of the wash compartment and accessories without a load and without an antifoaming agent using the

ORGANICA program (if available).

30

Effects of Processing Chemicals

Reactions between processing chemicals and soils

Effects

Natural oils and greases can be saponified with alkaline processing chemicals. This may cause a lot of foaming.

Action

– Use the program OIL (if available).

– Use the special program with emulsifier (neutral pH) metering for pre-rinsing.

– Taking the specific application into account, add an antifoaming agent, one without silicone oils if possible.

In combination with alkaline processing chemicals, loads with soiling that contains proteins, e.g. blood, can cause excessive foaming.

– Select a wash program with one or more short pre-rinses with cold water.

In combination with very acidic or alkaline processing chemicals, base metals such as aluminum, magnesium and zinc can release hydrogen

(detonating gas).

– Observe the instructions of the manufacturer of the processing chemicals.
