In soft serve and frozen yogurt machines, the logic board X36641SER2Refurbished Gen 2 Logic Board This item is sold with exchange...measures the viscosity of the product by monitoring the amp draw of the beater motor. When the machine reaches the set point, it cycles off and the product is ready. In auto mode, you can only adjust product viscosity, temperature in the freezing cylinder is not monitored.
The power board measures the amp draw. L1 power supplied to the beater motor goes through the power board on the beater terminals. Single phase and three phase units use the same Softech control, so the power board allows for different amp draw ranges. A jumper on the power board determines the amp draw range. Place the jumper on the pin that corresponds to the amp draw of the beater motor when the product is at the desired viscosity.
Setting Viscosity Adjustment
1. Place an amp probe on one of the L1 leads on the beater terminal on the power board.
2. Turn the viscosity adjustment screw to the "MAX" position.
3. With the freezer properly primed, press "AUTO".
4. During the freezing process, draw samples and inspect the product appearance. When the desired product viscosity and appearance is achieved, note the beater amperage.
5. Press "AUTO" to cancel the refrigeration cycle.
6. Using the chart, set what range the beater motor amperage falls into and place the jumper on the corresponding pin.
Viscosity Control Chart
2.4 pin - 1.2 amp to 2.4 amp
5.0 pin - 2.5 amp to 5.0 amp
8.0 pin - 5.7 amp to 11.2 amp
7. Press "AUTO". When amperage reaches the noted draw, turn the viscosity adjustment screw SLOWLY until the unit cycles off.
8. Draw several samples to verify the product and amperage when the machine cycles off remain consistent.
To increase viscosity, or make the product harder, turn the dial clockwise towards maximum. Important: The dial only turns a limited amount if it stops turning do not force it.
To decrease the viscosity, or make the product softer, turn the dial counter-clockwise towards minimum. The dial only turns a limited amount do not force it once it stops.
We recommend you only turn the dial about 1 hour on the clock, at a time. Once you have made your adjustment, pull the handle to start a new cycle, when the machine cycles off check the product again. X36641SER2Refurbished Gen 2 Logic Board This item is sold with exchange...
Every time I have seen that, it is just the USB cable on the mother board in the back of the machine.
1. Shut off and disconnect the machine from power
2. Remove the rear panel
3. Remove the electrical panel cover
4. Find the USB cable on the bottom of the board all the way to your right.
turn the power off and hit the reset buttons about the size of a quarter hole on the back or front panels. turn back on and it should clear if not then you will need to have the beater motor or contactor replaced.
That is most likely the stand by probe. The standby thermistor probe measures the temperature of product, in this case in the freezing cylinder, while the machine is in standby. Usually when the thermistor fails, you come in in the morning to find that the product is liquid and the reset has been tripped. The motor should be nowhere near the overload setting in standby as the product should be liquid. Thermistor probe C712 C713 Barrel Stanbye Probe
Viscosity adjustments should not have to be made frequently on these machines. If you change products a lot, such as flavors of yogurt, minor adjustments may be required. If your machine uses 3 phase electricity and it machine has been moved or any electrical work performed you may want to check the beater rotation, the beater should rotate clockwise inside the barrel viewing from the front, if you look at the gear box from the back, the pulley should be turning clockwise as well. Otherwise, there is a fine tuning potentiometer on the control, you must remove the front cover to see it. Clockwise is colder/thicker. I recommend small adjustments. It is best to read the amp draw on the motor to see what type of amps it is drawing. If your mix is soft and your motor is drawing 4 amps, you may have another type of problem such as a bad motor. The board and control can also fail giving these problems. There are many things to check in addition to these. Hope this will help you get started.
if your mix level is low ice cream will freeze in cylinder which in turn will over amp the beater and cause it to trip. Check mix pump and make sure all orings are good.If mix isnt leaking out make sure it is pumping in.
It is possible that your viscosity is set too cold. You should check the temperature of your product to see if it is too cold. Is the Ice Cream hard? It sounds like maybe the beater overload is tripping. Some of the overloads can reset on their own. If you have and know how to use an ammeter, it would be beneficial to check the amp draw of the beater motor to determine if you are exceeding the overload or not. Ice cream is generally good at a temp between 16 and 20 degrees F. Temps vary with product and product brands. I hope this information helps, it is hard to determine exact problem without being there.
