Introduction & Overview Objectives Know what the Qi is Be able to describe the function of the Matroller Be aware of comprehensive feed data O/P by the Qi Will know what type of equipment is supported by the QiMPACT Reference material: Qi – The BASICS.pdf
Qi Matroller position in a Batching System Last control component in the sequence Receives Target and Material info Reports back to Control system at the end of the Feed Recipe Target & Material Path HMIPLCQi Matroller Qi processes the Recipe One Material (Phase) at a time. Database of Materials used is kept in the Qi Batch Server Multiple Recipes
Functions – what is it and what does it do ? Its a Weight indicator and Flow meter totaliser ! Can be part of a Batching System OR stand alone control Does not store a recipe internally. Suitable for single valve control (single feed) Accurate Feeds at SPEED (High Flow Rates) –Uses P&Gs patented Predictive Control Algorithms Monitors Flow Rate during the Transfer cycle and continuously adjusts the cutoff point –Very fast, 20 mS comparator for scales Flowmeter even faster! Provides consistent Material Feed Interlocking –Consistency throughout the world! Provides Comprehensive Feed reports Qi Lite can handle two speed control GROUP FEED Capability (Qi Lite)
Qi Functional capabilities – not just accuracy Feed Accuracy at Speed –Maintains Feed accuracy at High Flow rates and varying Flow Rates ! By means of sophisticated Predictive Control Algorithms (PAC) Material Feed management –Built in Feed Interlocking Will not allow simultaneous Feed In and Discharge out of the same Scale –High limits, Low limits, silly Targets –Instrument accuracy crosschecking –Overlapping feeds for a more efficient process Feed Data Logging –Comprehensive data output at end of every feed Note: must be captured by Host Computer –Data such as: Net amount Fed, Feed duration time, Gross weight at start and end of Feed, Average Flow rate, Flow rate and Spill at Cutoff, Internal Algorithm constants etc All this is built into, and comes standard with the Qi. Thus reducing the amount of code within the PLC, reducing cycle time and code writing time. This means a consistent solution to feed control throughout the World Simplifies maintenance and support
Review questions Does the Matroller require a PLC when performing batching functions? What are the three main functions of a Matroller? Can the Matroller function as a standalone Scale display?
