MCK880E packaging machine control instrument Safety Precautions: Before the controller access to power, voltage, check whether the use ~ 220V ± 15% within the range of 50HZ ± 2% within the scope and frequency is in. If you use a power supply can not meet this requirement, the need AC power supply. If you have installed the sensor on the device, the welding work on the device should be avoided. Must be welded, welded parts to the nearest grounding, ensure the sensor without any influence of the welding current, if the sensor controller has access package, then all welding work on your part of the mechanical structure of the device will be absolutely not allowed. Summary I. Introduction MCK880E weighing display controller is designed for the chemical, food and other packaging machines provide automated quantitative computer controller. This machine is a single-chip computer control, weight control set in one of the smart meter. Has a unique anti-jamming, can be used in harsh environments and long-term. Second, the main function of a set amount of control ● ● ● Working status LED indicates the thickness of the flow control setting ● ● sensor range sensor sensitivity setting parameter setting Tare function ● Third, the basic working principle MCK880E weighing display controller to accept the sensor output The analog signal, after an internal collection signal processing, calculate and display the value of the body weight of said material. The weight value and the set value is compared symmetrical body material, such as weight value reaches the set value, the controller signals to the execution devices (e.g. be thick stream feed, discharge, out of the bag and other actions).
