How to set the shutdown time manual of the Ecokey on the Delong coffee machine

If you are using a Delong coffee machine in your company, it is recommended not to use coffee powder, because if you add no more than 2 tablespoons of coffee powder at a time, it will damage the machine. In addition, adding only one spoonful of coffee powder at a time is too slow for the unit to make coffee. In addition, the taste of coffee powder is not as fresh as coffee made from coffee beans. If you do not use the coffee machine for a long time, it is recommended to use all the coffee beans in the warehouse, otherwise it is easy to cause clogging of the coffee machine grinder. The coffee barn should be kept dry. In the wet season and in some areas, special attention should be paid to the coffee machine when working, to keep the water tank with enough water and not lack of water to burn dry (users of the Delong coffee machine need not worry too much, because the water tank of the Delong coffee machine has the lowest water level protection function. Will prompt the alarm to add water), can not draw out the water tank, otherwise it will damage the machine. However, the water used in the coffee machine requires the attention of consumers, and pure water is recommended.

The extractor can not be taken out, so observe that the extractor is at the top. One, two, the alarm light is always on.

After entering the functional test mode, the extractor can move up, but not down. after inspection, the extractor motor is broken, replace the motor and troubleshoot.

The voltage at both ends of the motor is normal. When moving up, F8 is positive, F7 is negative, and the voltage value is 200V. After reaching the top, the voltage disappears and 1 cup light is on. When the 2-cup key is pressed, the extraction part walks downwards, F8 is negative voltage, F7 is positive voltage, and the voltage value is 200V. After reaching the bottom, the voltage disappears and the 2-cup lamp is on.

One drink, two drinks, warning light on.

It may be that the extractor motor is broken, the general motor resistance value is about 200 ohms, if it is too small or open, it should be judged as motor damage. Since this motor is a DC motor, the measuring motor needs to be turned to the motor by hand, and the resistance value is measured in each gear.

If the resistance value is too small, the circuit board may also be damaged, so the circuit board cannot be replaced first, lest the motor burn the circuit board again. If the power is plugged in and the relay sound on the circuit board cannot be heard, it is estimated that the circuit board needs to be replaced.
