Page 4: Chapter 1 Profile
MI114 User Manual Chapter 1 Profile MI114 uses an advanced delta-sigma A/D converter to achieve a higher speed and higher accuracy for batching or packing systems. The MI114 single chip microprocessor and high-speed Σ-△A/D switch technology performs conversions and displays weight, with the maximum conversion speed of up to 80 times/second. The display can be easily connected to the strain gauge based load cells to form batching scales, packing scale, weighing control systems etc , where high-speed and high precision weighing are required. -

MI114 Manual Chapter 5 Operating Instructions I. Startup and zero setting upon startup After connecting to the power supply, the display performs self-check of strokes “0-9”, then shows the version No.. After that, it enters into weighing mode. After startup, if the weight of empty scale deviates from zero point, but remains within the zero range, the display will perform zero setting upon startup. -

MI114 Manual Chapter 6 Explanations of Control Procedure The four working modes of the indicator are explained in details as below: I. Mode 0（additive mode with 1 batching material） The double-speed batching of 1 kind of material mainly involves the following parameters: batching value A1, quick feed lead b, slow feed lead C, allowance, zero value L. -

MI114 Manual feed are ON during quick feed process, and gradual feed exists. The schematic diagram of slow feed 2 shows the slow feed output when only the quick feed is ON during quick feed process, and without gradual feed. - Page 24 MI114 Manual subtraction is ON during quick subtraction process, and without gradual feed. The control procedure in the above diagram consists of 4 processes including quick subtraction, slow subtraction, gradual feed allowance treatment and discharge. （1） Quick subtraction -- When the control procedure starts, the quick subtraction output gives out a signal, and the corresponding O1 relay is closed.
- Page 25 MI114 Manual （4） Discharge-- Discharge output sends out a signal, and the corresponding O3 relay is closed. After the delay of t5, the discharge output signal is cancelled, and the corresponding O3 relay is switched off. A complete control procedure is finished.

MI114 Manual （2） Gradual feed out-of-allowance treatment of material 1-- After the delay for a period of t1 (feed over delay of material 1), if the parameter is set with gradual feed, the O2 relay corresponding to feed of material 1 will be closed for a period of t3, and switched off for a period of t4. Gradual feed is carried out through such repeated cycle, until the weight reaches up to the allowance range of batching value of material 1, i.e. - Page 28 MI114 Manual Parameters Indicator display Parameters instructions Remark Self-check mode: automatic catch weighing is started when the weight is bigger than that in zero zone [FodE *] Upper and lower limit mode: real time upper limit, intermediate limit and lower limit...
