When a programme is selected, the associa-
ted mixing time is shown on display B.
7.2 Displaying Mixing
Parameters
The mixing parameters of the currently selected
programme can be displayed at any time (refer to
Sec. 7.1 for instructions on how to select a pro-
gramme).
Displaying the parameters:
• Press the desired parameter key (Figure 22).
• The LED under the parameter key goes on.
• The parameter value continues to be shown on
display B for approx. 6 sec. Or until another key
is pressed.
When setting a programme, the LED under
the parameter keys will remain on for approx.
2 seconds if the value for the associated
parameter is not equal to zero.
7.3 Setting / Saving Mixing
Parameters
Only the mixing parameters of the currently selected
programme can be changed and saved (refer to
Sec. 7.1 for instructions on how to select a pro-
gramme).
1. Changing and permanently saving a selected
parameter:
• Press the desired parameter key (Figure 22).
• The LED under the parameter key goes on for
approx. 6 seconds. The value can be changed
and saved while the LED is on.
• Adjust the value by turning the control knob (Fig-
ure 23).
• Press the parameter key again (Figure 24) until
the audible indicator sounds (after approx. 1 sec-
ond). This indicates that the new value has been
permanently saved.
2. Changing and temporarily saving a selected pa-
rameter:
• If changed values are not permanently saved as
described in item 1 above, they apply only to the
next mixing process.
• Once this process has been completed, the pre-
viously programmed values will again apply.
Any parameters, which are changed during
the mixing process, also only apply to the
current cycle. At the end of this cycle, the
previously programmed values will again
apply.
7.4 Premix Function
The Twister evolution offers the option of selecting
one of two premixing functions:
• Premix function for plaster (Figure 25a);
• Premix function for investment materials
(Figure 25b).
The premixing process for both functions lasts no
more than approx. 25 seconds.
Depending on the amount and type of mixture in
question, a good mixing result can also be obtained
from a shorter premixing process.
You can set the premix time as follows:
• Display: 0:00
• Display: 0:15
• Display: 0:20
• Display: 0:25
Your selection is shown on display B.
Only one of the two premix functions can be activated
at any given time. When one function is activated, the
other is automatically deactivated.
Activating and changing the premixing function is
performed in the same way as changing any other
mixing parameter.
The LED under the associated premix function going
on indicates which premix function is activated in
conjunction with a given programme.
To deactivate the premix function:
• Select a premix function (by pressing one of the
premix keys);
• Turn the control knob until the display reads
0:00.
Selection and saving is performed in the same
way as changing a parameter, by:
• Pressing one of the premix keys (Figure 25a
or b);
• Adjusting the value with the aid of the control
knob (Figure 19);
• Saving the changed value by again pressing the
premix key until the audible signal sounds.
Just as is the case for any other parameter, the
premixing time can also be changed during the mix-
ing process.
However, the premixing time can only be changed in
5 second intervals to achieve a total premixing time of:
• 15 seconds, or;
• 20 seconds, or;
• 25 seconds (maximum).
Just as is the case for the other mixing
parameters, these changes only apply to
the current mixing process. The previously
programmed values will again apply to the
subsequent mixing process.
7.5 Resetting the Parameters
Upon delivery, all programmes contain exactly the
same values for all parameters (refer to the table in
Sec. 5.1 for a list of the factory settings).
To reset all parameters and all programmes to their
factory settings:
1. Switch the unit off;
2. Press and hold down programming key "P";
3. Switch the unit back on (while continuing to press
programming key "P");
4. Continue to press programming key "P" until the
audible signal goes off (after approx. 3 seconds).
