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.
thespeedsystem:
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.
generaldesCriptionof 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.

IF THE ELECTRONICS IN THE CONTROL BOX FAILS,
THE MIXER CAN BE OPERATED MANUALLY.
1. Turn off the main switch at the point of connection.
2. Open the mixer’s lid and toggle the switch which is placed on the rear of the control box to “MAN” position.
3. Dismount the servo motor from the arm by removing the pin (T).Tietheservomotorshaftrmlysothatitcannot
touch the special V-belt when the mixer is started.
4. Remove the cover on the right side of the mixer and place the speed selector lever (R) in the slotted shaft. The
speed selector lever was included with the mixer either separately or in the mixer.
5. Close the mixer’s lid and turn on the main switch.
6. Start the mixer by pressing START
7. The speed can be changed on the speed selector lever (R).
8. Stop the mixer by using the EMERGENCY STOP SWITCH instead of the normal stop key.
WARNING: In this working position the security systems of the mixer are out of function.
This means that the mixer can be running with the bowl lowered and the safety guard
and the cover open.
adjustmentsofspeed (lowandhighspeedCamdisKs):
1. Prior to any adjustment the mixer must be at minimum speed, the bowl must be in “UP” position and the safety guard, if
equipped, must be closed.
2. Press the emergency stop switch.
3. The cable to the servo motor must be disconnected at the rear of the control box. The socket is marked “SPEED REG”.
4. The slide switch on the rear of the control box must be in the “MAN” position.
5. The arm (U) is released from the servo motor shaft by removing the cotter pin (E) and the pin (T). The arm (U) must not
be loosened from the shaft (V).
6. The manual speed selector lever (R) included with the mixer is placed in the shaft (A) so that it points upwards and forwards. (Remove the cover from the side of the mixer).
7. Release the emergency stop switch and start the mixer, increase the speed with the selector lever until the distance (H)
on the rear pulley is 0-3 mm: “HIGH SPEED”.
8. Stop the mixer by pressing the emergency stop switch on the control box.
9. Adjust the high speed cam disk (V2) so that it is activating the micro switch. “MAX light should be on”.
10. Release the emergency stop switch and restart the mixer, with the manual speed selector lever, lower the speed until
the distance (H) is 0-3 mm on the front pulley set: “LOW SPEED”.
11. Stop the mixer by pressing the emergency stop switch on the control box.
12. Adjust the low speed cam disk (V1) so that it is activating the micro switch: “MIN light should be on”.
13. Reconnect the cable from the servo motor to the control box. The socket is marked “SPEED REG”.
14. Move the switch on the rear of the control box to “AUTO”.
15. Remove the speed selector (R) and replace the cover on the side of the mixer.
16. Mount the pin (T) and the cotter pin (E) which connects the arm (U) to the servo motor shaft.
BE AWARE THAT THE SERVO MOTOR SHAFT MUST NOT
TOUCH THE SHAFT (A) IN MAXIMUM SPEED.
17. Release the emergency stop switch.

error Codes:
An error in the mixer will trigger an ERROR code in the time display. See the below mentioned explanation of error codes
and the procedure for correcting them.
E:201 The servo motor block actuator (B) did not contact the minimum speed micro switch (A) after the stop button was
pushed or the programmed recipe completed.
The computer is programmed to slow the mixer down to low speed before shutting off. It will not do this unless the micro
switch is contacted by the block mounted on the speed adjustment shaft.
To correct this error:
1) Check the micro switch (A) to see if it is working by manu-
ally pushing it, when pushed, the “MIN” light should light up
on the control panel. If it does not, the micro switch is faulty.
2) The cam disk (B) is not contacting the switch, adjust the
switch up.
3) The servo motor is not moving at all. Check the fuses in the
rear of the control, if blown, replace, if not blown, check the
voltage (31 VDC) at the servo motor while the mixer is running. If voltage is present, the servo is faulty.
12
E:301 There is no signal from the speed pickup (hall effect sensor).
To correct this error:
1) Check that the sensor (D) is centered directly above the track of the 3 magnets (F) on the pulley and the gap between
the sensor and magnets is 1/16”. If not, bend and / or move the bracket (I) holding the sensor.
2) Inspect the three wires between the sensor and the plug. Replace the sensor if wires are broken.
3) Insure the aluminium disc (E) is tight on the pulley.

HOT The thermal overload F2 has tripped because of excessive amp draw or heat.
The overload will automatically reset after it has cooled. This function is to protect the mixer.
To correct this error:
1) Have a service technician inspect all wiring, contactor and overload for faults.
2) Monitor the amp draw while the unit is operating. If excessive, the drive motor may be failing.
