speCial starting proCedure to be used after:
1. STOP WHEN USING THE EMERGENCY STOP SWITCH.
2. STOP DUE TO OVERLOADING.
3. STOP DUE TO OPENING OF SAFETY GUARD WHEN THE MIXER IS RUNNING..
The bowl must be removed from the mixer before starting the mixer again. The mixing speed must be reduced to low speed before the bowl is placed in the mixer.
If the mixer is started without removing the bowl, it must be possible for the mixer to obtain approx. 75% of the minimum speed. If this is possible, the mixer will automatically return to lowest speed and stop. After pressing “START” the opera- tion can be continued in the normal way. If the mixer cannot achieve approx. 75% of the minimum speed due to continued overloading, the error code E501 will appear. The bowl is now to be removed from the mixer. After a pause of 2 minutes, “START” can be pushed again, and the process can be continued.
the speed system:
THE SPEED REGULATION OF THE CONTROL PANEL IS A FEEDBACK-SERVO-SYSTEM. This means that a pick-up
(magnetic sensor) is constantly supervising the speed of the main shaft, and reports back to the control panel.
The actual speed of the tool is constantly compared with the required speed, and the computer of the control panel will send a signal to the servo motor in order to adjust the speed if the comparison is showing a greater difference than +/- 10
RPM.
general desCription of modes:
The system contains six different modes:
1. MANUEL MODE: The mode when the mixer is operated like a manual controlled mixer. Instead of executing a programmed recipe, the mixer is started and operated until it is manually shut off.
2. PROGRAMMING MODE: The mode where all programming and editing takes place.
3. PROGRAM MODE: The mode where all programmed recipes are executed.
4. FIXED MODE: A pure executional mode, mixer will only run the programmed recipes.
Neither editing or speed/time overwriting can take place. Manual mode is void.
5. RPM MODE: Computer displays the speed in actual R.P.M.
6. SPEED MODE: Computer dispalys the speed. (Speed 1,2,3 and 4).
overloading:
Sticky and heavy doughs may reduce the performance of the mixer. The performance is further reduced if the speed of the mixing tool is increased beyond the recommended values or if a wrong mixing tool is used. Large lumps of fat or cooled ingredients must be cut into small parts before they are placed in the bowl.
THE SPEED SYSTEM CONTAINS AN AUTOMATIC PROTECTION SYSTEM AGAINST OVERLOADING OF THE MIX­ER. The computer of the control panel will always try to keep the mixing speed at the same level as the keyed in speed.
If the mixer cannot run with the required speed due to overloading, the computer will reduce the mixing speed to a value corresponding the loading capacity of the mixer.
IN CASE OF OVERLOADING THE FOLLOWING WILL HAPPEN: The speed keyed in by the operator on the control panel will, depending on the loading, be reduced by up to 20%. This speed reduction can occur several times after each other until the speed corresponds the loading capacity of the mixer. If this happens, the operator must reduce the speed on the control panel or reduce the amount of dough.
Prolonged overload will make the mixer’s motor protection disconnect the mixer. Leave the mixer for approx. 3 minutes whereafter the mixer can be restarted.

Keypad:
The keypad is used for entering data to the system and for gen­eral operation of the mixer.

A step is always a combination of speed and time.
An examlpe is 100 R.P.M for 5:00 minutes or 0 R.P.M for 15 seconds (which is a 15 second pause). Please note that the mixer will not start automatically after a pause, the start button must be pushed to proceed to the next step.
Up to 25 programs, each consisting of 9 step, can be stored in memory.
A sample program:
Program number Step Speed Time
1 1 60 1:00 2 200 5:00 3 0 0:20 4 110 4:00 5 180 2:00 6 0 0:00
“0” Speed and “0:00” Time in the last step is mandatory. The control system will read it as a “end of program” mark
how to program a reCipe:
Push
“HOLD FOR 3 SECONDS”
Push
Push
Enter the speed desired
Push

.
Enter the time desired
Repeat this process for as many as 9 steps per program, after the 9th step, the next program number will display, ready to enter a new recipe. This will continue up to 25 programs.

Example:
ENTER
To edit a recipe or to correct mistakes, press “PROG” and hold it for 3 seconds to enter the programming mode, then push “ENTER” to reach the program/step that you wish to edit.
To delete a recipe, use the same step above to enter the programming mode, then push “ENTER” to reach the program/ step that you wish to erase. Enter “0” in speed and “0” in time in all steps.
how to run a programmed reCipe:
Push
Enter the program number
Push
Push START
After the “ENTER” key has been pushed, the data in step 1 will be displayed along with the program number.
After the last program step has been executed, the mixer will slow to minimum speed and shut off.
The mixer can be stopped at any time during a recipe by using the “PAUSE” button, the mixer will slow to stop and the recipe will not be lost. To continue on with the same recipe, push “START”.

fixed mode:
Fixed mode is basically designed for users who operate the same recipes over and over again without frequent updating.
Themaximumnumbersofprogramsavailableinxedmodeisreducedfrom25to10.
Fixed mode is a purely executional mode, its not possible to adjust the speed or time while in this mode.
The mixer will only run recipes that are programmed.
The advantage to this mode is that no one can “cheat” the programmed recipe.
The only applicable keys are “START”, “STOP”, “PAUSE”, “BOWL LIFT”, Emergency stop and numeric keys.
