    							2.5.3 General Information - Service Mode 1
    Service mode 1 can be used to advance through the individual program steps of a
    selected program. Steps should be advanced rapidly with a maximum of 2
    seconds of pause. If a step is not advanced, the selected program is continued
    normally from the step reached. The parameters affecting the fault-monitoring
    system also apply during the service mode. If, e.g., a heating step is accessed,
    then a fault is registered if sufficient water has not previously entered the cabinet
    (water level is checked via the heating level switch). After the start of a program,
    the current program position is shown via the program sequence indicator. The
    wash block display is suppressed and the actual temperature is shown normally
    when selected via the top program function button. TheDryingfunction can be
    selected or deselected via thecbutton before the start of a program, if it is
    normally available for the program being checked.
    A cleaning program selected in service mode 1 can be quit or interrupted as
    follows:
    –Open the door
    The door lock is not active in service mode 1.
    The cleaning program is interrupted and, when the door is closed again, the
    program continues in service mode 1 from the step reached.
    –Shut off the machine
    The cleaning program is interrupted and, when power is restored, the program
    continues in service mode 1 from the step reached.
    –Turn the program selector switch to the 12 o'clock setting
    The selected cleaning program is interrupted or the program currently selected
    but not started is canceled. The electronic is still in service mode 1. A different
    program can now be selected and started.
    –Quit service mode 1
    Turn the program selector switch to the 12 o'clock setting and shut off the
    machine.
    2.5.4 General Information - Service Mode 2
    x
    Note
    Before making settings in service mode 2 the fault memory should be checked.
    If service mode 2 is quit with saving, then all entries in the fault memory are
    deleted.
    Service mode 2 can be quit without saving any parameter changes that may have
    been made by interrupting the power supply in some way (e.g., by opening the
    door). Service mode 2 is divided into 6 or 7 service levels (S 21toS 26orS 27,
    depending on model). Printer interface data can only be modified or displayed if a

    							printer interface is present and activated. When stepping back and forth through
    the various programming levels the active programming level is onlydisplayed,
    e.g.,S 23, when the program selector switch is turned to the 12 o'clock setting.
    Settings in service mode 2 always apply for all cleaning programs, except when
    impermissible settings have been made in individual cleaning programs. Service
    mode 2 can be quit without saving any parameter changes that may have been
    made by interrupting the power supply, e.g., by opening the door.

    –Software index P 02 (ID 524)
    –Software index P 03 (ID 560)
    Introduction of service mode function S 27.
    –Software index P 04 (ID 585)
    1. Parameter adjustment of all "vario TD”programs.
    The washing parameters of programs "vario TD", "vario TD AN" and "B"
    (vario TD NR of G 7882/CD) increased from 113°F (45°C), 3 minutes, to
    131°F (55°C), 5 minutes.
    2. Additional rinse in program SPECIAL 93°C 10 min.
    The rinse SP 3 with reduced water quantity has been activated for
    program SPECIAL 93°C 10 min in order to prevent carryover of salt from
    a reactivation cycle (especially important in the dental field). The change
    applies to all machines that use this program.
    3. Modification of water intake for vario TD.
    In order to ensure better cleaning performance, the second water intake
    for "vario TD" programs is also carried out with cold water. This makes no
    difference in models G 7881, G 7882 and G 7883, as they do not have a
    hot-water connection. This change means that in G 7882 and G 7883 CD
    models, the second water intake is now with cold water.
    4. Drainage times - Steam condenser (DHK).
    The drainage cycle of the aerosol-injection steam condenser has been
    modified in order to remove water that has entered from the wash
    process before closing the steam condenser vent opening.
    5. Introduction of function to block STOP.
    Service mode level S 26 has introduced a function at selector switch
    setting 2 which prevents program interruption by selecting STOP.
    However, if a fault occurs during a program that leads to program
    interruption, the STOP setting for fault acknowledgement is still required.
    6. After ventilating a dispenser with pump, a "0" is no longer displayed but
    "dox", where the x represents dispenser number 1, 3 or 4.

    							1. If an aerosol-injection steam condenser is installed, the steam condenser
    (DHK) pause can also be activated without drying in order to, e.g.,
    reduce the level of steam escaping with high-temperature programs.
    2. Depending on model (with/without steam condenser (DHK) and with/
    without drying unit (TA)), service mode 2 (level S 26 - Function 3) offers
    various options as follows:
    1. S 26 - "-": DHK (aerosol-injection steam condenser) not installed
    2. S 26 - 30: Without additional steam condenser (DHK) pause
    3. S 26 - 31: With additional steam condenser (DHK) pause when
    drying is not active (applicable to models with/without drying unit
    (TA))
    4. S 26 - 32: With additional steam condenser (DHK) pause when
    drying is active (applicable only to models without drying unit (TA))
    3. The G 7882 CD is supplied as standard without rinse aid dispensing. If a
    new electronic module is supplied as a spare part, it must be
    programmed to activate rinse aid dispensing if this had previously been
    set.
    4. G 7883 and G 7883 CD–The dispensing options in program block
    CHEM-DESIN have been extended. The order of the setting figures has
    been adjusted.

    5. Reduction of cleaning temperature level E 01- Function 10.
    Previously the reduction of the maximum temperature from 93°C to
    90°C was only carried out correctly in program block HR1. As in this
    block the parameters of SPECIAL program are also defined; duration
    here was also correctly automatically extended from 10 minutes to 25
    minutes. All other temperatures > 90°C then also had to be reduced
    manually. This is no longer necessary with the modified software.
    6. Time basis for ventilation functions (programming mode) modified.
    The time basis for automatic ventilation functions has been modified from
    1.1 seconds to 1 second.

    							7. If a reduced water quantity is programmed in program blocks VR2, SP1
    or SP2, then heating should not take place in these blocks because the
    wash pressure is not sufficiently constant and this can lead to the
    registration of a fault (F 3EorF 27). The interdependence has been
    adjusted.
    8. With the electronic module EGPL 081 P 05 (ID 860), a diagnostic
    support file (DUD) for the Miele diagnostic utility (MDU) has been created
    for the first time.
    9. In the programming mode, the range of dispensing options in program
    block CHEM-DESIN has only been extended for the G 7883 and G 7883
    CD. However, values for the other machines have been modified. In
    service mode level S 26, two new functions have been added under
    positions 3 and 4. The program summary of G 7882 CD has changed
    with regard to dispensed agent utilization in the final rinse stage.
    –Software index P 06 (ID 1180)
    1. Clock setting in customer programming mode.
    Sometimes the service department is needed to make the changeover
    from summer time to winter time and vice versa. In order to offer the
    operator the possibility to set the clock time himself, programming mode
    level E 34 has been created with which the time and date output at the
    printer interface can be set. The functionality is equivalent to the clock
    setting function at service mode S 22 (functions 3 to 7). However,
    settings will only be accepted if the interface has been activated in
    service mode S 21. Several seconds may elapse before the current data
    is output via the interface. Default values are displayed until the current
    data can be shown.
    2. In order to be able to follow the actual program structure on a printout,
    program block names where no special parameters (such as dispensing
    or wash temperature) are set are now also printed.
    3. Machine number index.
    With the introduction of the new control, the packaging of new machines
    is printed with the number 062 (clock setting for operator).
    4. Drain pump pause.
    To improve drainage, 2.2 seconds after the drain pump has started, it is
    stopped for 2.2 seconds and then operated normally until the drainage
    time has elapsed. This action improves pump ventilation.
    5. I
    2C bus fault.
    Under certain circumstances, communication problems of the I
    2C bus
    might not be registered. This only affects communication with the
    additional module EZL 031/081 and is indicated with fault codeF 11. If

    							this fault is registered when an interface is active, the fault codeF 13is
    always correctly generated. The modified software ensures that this
    communication problem is correctly identified.
    6. A new diagnostic support file (DUD) for the Miele diagnostic utility (MDU)
    has been created for electronic module EGPL 081 P 06 (ID 1180).
    7. With the introduction of the new control, the machine technical
    documentation is no longer located behind the cover plate under the
    door, but is now included with the machine accessory pack which also
    includes the operating instructions.
    –Software index P 07 (ID 33960)
    1. Hot-air drying filter time reset.
    In machines with software index P 06 with a drying unit (TA), both filters
    are always active. As new G 7891-93 models have only one fine filter, the
    use of a single filter is taken into consideration. This modification has no
    effect on previous machine versions.
    2. Creation of a batch number.
    The protocol (report) function has been extended to include the creation
    of a batch number and the printer interface has been modified
    accordingly. The control transmits a 2-digit version number, which can be
    created via the diagnostic support file (DUD) to the interface, and the
    interface creates a 6-digit sequential batch number. The version number
    is required in order to be able to differentiate between new and old
    protocols should the printer interface be replaced because a new
    interface always starts with the number 000001. With version number 00,
    the creation of a batch number is suppressed. In old control versions up
    to P 06, a batch number is not created, even with a new interface.
    3. Door lock.
    The routine to lock the door has been modified. From software index P
    07, the door is locked immediately after a program has started.
    4. Dispenser relay control with EZQ 081.
    Due to a change in legal requirements, all disinfectors with the control
    family MC Novo must be fitted with a dispenser relay control by the end
    of 2007. This is to be certain that continuous dispensing can be definitely
    avoided. In order to ensure backwards compatibility with older controls,
    service mode S 26 has been extended with function 5.

    							F 32: Faulty activation, dispenser relay on EGPL or EZL stuck
    (dispensing relay).
    F 33: Maximum permitted activation time exceeded (dispensing time).
    6. Control modifications, corrections and extensions.
    The automatic ventilation times stored in the electronic module have
    been adjusted for the internal dispenser pump DOS 3.
    When an electronic module is reset, the dispenser control settings (E 02
    - Functions 9 - 11) are no longer overwritten. This means that now when
    an old electronic module is replaced with a new one and the flow control
    is deactivated at the same time, this will not be reactivated after a reset.
    7. Creation of new diagnostic support file (DUD).
    A new diagnostic support file (DUD) for the Miele diagnostic utility (MDU)
    has been created for electronic module EGPL 081 P 07 (ID 1290).
