1Key definition:

1)AHeating button: Start/stop temperature control. In the heating state, long press to switch between two temperature sensor displays. In a non set statePress and hold to switch heating parameters and self-tuning.

2)DRotation key: Start/stop motor operation. When the motor is in a stopped state, long press to switch between setting the motor's forward and reverse running speeds. When F033 is not 2 while the motor is running, long press to switch the direction of motor operation.

3)B settingKey:Short press to lock all panel parameters to prevent accidental operation, long press to set key

4)CTimer key:Short press to set timer, long press to set program temperature control, (depending on machine model)

twoOperation and usage methods

1)After the system is powered on, it controls the motor, temperature sensor, and heatingmodulePerform self inspection. The top column of the display window shows the corresponding status. If the icon flashes, it indicates that the device has a fault.

2)Temperature setting: In the non set state, the set temperature value can be changed by rotating the heating button. The set temperature value flashes, and the temperature setting is completed by pressing the heating button again. If not confirmed, the previous set value will be restored after 5 seconds.

3)Speed setting: In the non set state, the set speed value can be changed by rotating the rotation key, and the set speed value will flash. Press the rotation key again to complete the speed setting. If not confirmed, the previous set value will be restored after 5 seconds.

4)Run time setting: In non set state, a single timed time can be set. Press the timer button, and the timer value will flash. Rotate the rotation key to change the timing value, press the timing key again, and the single segment timing time is successfully set.

5)Heating PID parameter selection: When selecting an external sensor as the heating feedback,According to the heating rangeDifferent heating PID parameters can be selected. Long press the heating button to display HEAT on the left. Rotate the heating button to select 4 sets of PID parameters from 0 to 3 on the right. Short press the heating button to confirm the selection and exit.

6)Multi stage temperature control setting: Long press the timer button to enter the multi-stage temperature control setting. SET represents the number of temperature control segments that can be set, SP01 represents the set temperature for the first segment, T01 represents the set time for the first segment, and eight segments can be set. When SET is set to 0, it runs according to the set time of a single segment. The value can be changed and confirmed by rotating the rotary key. After setting, long press the timer button to exit the multi-stage temperature control setting.(Depending on the machine model)

7)When overcurrent fault, bus overvoltage, bus undervoltage, motor stalling, Hall error, motor stall, temperature sensor failure occur, the motor automatically stops running and the corresponding alarm information is displayed on the interface.

threeSystem self-tuning

When the temperature control effect is not ideal, system self-tuning can be performed. During the self-tuning process, there may be significant temperature overshoot. Users should fully consider this factor before performing system self-tuning.

Long press the heating button to display HEAT on the left, turn the heating button to set the value on the right to 4, and short press the heating button to confirm. On the right side, the flashing display shows' AT '. After the setting is completed, the system automatically returns to normal operation. After the tuning is completed, the controller will obtain a better set of PID parameters, and the parameter values will be automatically saved. During the system self-tuning process, resetting the self-tuning parameter to a value other than 4 can terminate the self-tuning program.

fourInternal parameter setting

Long press the lock button to enter the password input interface, rotate the rotation button to change the value to 8, and press the rotation button to enter the parameter setting interface. Rotate the rotation key to select the parameter that needs to be modified, press the rotation key, the parameter value flashes, continue to rotate the rotation key to modify the parameter, and press the rotation key to confirm the modification. If not confirmed, the previous set value will be restored after 5 seconds. Long press the lock button to exit the parameter setting interface.

Precautions:

l1. Do not dry burn for use.

l2. The instrument should have a good grounding.

lWhen used for the first time,heaterThere is white smoke and odor coming out inside, which is a normal phenomenon due to the internal insulation materialAnd insulation materialsDuring the production process, oil and other compounds should be stored in a well ventilated areaIn the kitchenAfter disappearing for a few minutes, it can be used normally.

l4. Due to the limited temperature resistance of the motor and magnet of the mixer, the instrument cannot be used solely for heating during heating tests, especially high-temperature heating tests,pleaseAdjust the motor to the rotating state（500To prevent damage to the motor, magnet, and high temperature radiation.

lWhen the high-temperature heating is completed, please turn off the heating first and wait for a few minutes for the remaining temperature to dissipate before turning off the stirring.

l6. The heating part has a high temperature, so be careful when working to avoid burns.

l7. When wet hands, liquid overflow, or long-term exposure to high humidity, there may be induced electricity transmitted through the insulation layer to the outer shell. Please ground the wire and pay attention to ventilation. If the leakage is severe, please do not use it again. It should be dried in the sun or in an oven before use to avoid danger.

l8When not in use for a long time, please keep the instrument clean and store it in a dry and non corrosive gas place.

l9.If there are any differences in the content of this manual due to improvements made to the product or the products mentioned in this manual, no further notice will be given.
