HAVER Weigher Electronics MEC III Data Processing System DPS V4.1
HAVER Weigher Electronics MEC III
The MEC III results from the continuous development of the 6th generation of HAVER electronic weighers. Up to now, more than 12,000 electronic weighers are used worldwide on HAVER filling machines.
• status information • error messages The simple and well-structured operational sequences are done through menus or via function keys with actual pictograms. Text and numerical values are inputted using the combined alpha-numeric
keypad. The plain text information may be displayed in many national languages. For the appropriate setting of the filling machine, there are aids for analyzing the filling process with respect to the filling time and the mass flow rate.
The MEC III is a PTB approved electronic measurement device that can be calibrated and has a resolution of 6000 increments. It may be operated as multi-range or multidivision weigher with three different increment settings. The zero-setting is done via a dialog and may be securely stored against power outages. In addition to the weighing functions, the MEC III controls machine functions via digital inputs and outputs. The operation and display of all functions is done through an external control terminal. This terminal has a contrast gra phic display for showing all operational situations such as: • weight values • weigher settings • dialogs

Technical specifications of weigher features: • gross / net • taring / zero setting • dosing time regulator • after-flow regulator • dynamic filling cut-off point • filling by weight or by volume • tolerance evaluation • adjustable weigher signal damping • bag breakage detection • regulated filling vessel aeration as a function of mass flow rate • product memory for 99 sorts • weight correction by an end-of-line check weigher is possible The computer unit is modularly designed. It consists of an operating unit, keypad, display and the control unit. The operating unit is easily accessible and is built into a switch cabinet door, while the control unit module is placed inside the switch cabinet. All electrical connections to the modules are plug-in type, which makes exchanging components an easy task, even for non-specialists.

HAVER DPS 4.1 data processing system
Initial screen DPS V4.1
Menue screen – settings – lines – designations
The DPS 4.1 data processing system is a program for collecting, reporting and recording process data that can be read and stored over the serial interfaces of a PC using the Windows 95, 98 or NT 4.0 and Windows 2000 operating systems. Data from HAVER weigher control systems or servers for ROTO-Packers and their check weighers are collected. Up to eight packing lines can be processed and administrated simultaneously using a PC equipped with the appropriate interface equipment.
The dialog language is selectable from a menu. The following data may be collected: line number, weigher number, sort designation, actual weight, specified weight, tare weight, overweight limit, underweight limit, sort changeover, error messages, weigher status and plain text messages. From this data, the following values are reported: mean weight, standard deviation, total weight, total bag count, number of good bags, underweight bags and overweight bags, hourly bag pro-

duction, information about charge start and charge stop time. Reports such as machine reports, daily, weekly, monthly and yearly reports, error reports and single weight reports may be printed out. From a single weight report, a weighing diagram or a Gaussian distribution curve can be generated.
The packing line can be shown in a total of 8 different statistics windows. Here, every packing line may be assigned to a statistics window, or more than one line may be assigned in groups to a statistics window. For every statistics window there are 15 data columns for inputs such as actual weight, of which 7 are visible on screen. The operator

Selection of data columns in statistics window 1 Single weight report in diagram format
can switch over to other data columns. 150 bytes of memory capacity are needed per data set for one filled bag. That means data for 40 million filled bags can be stored on a hard disk with 6 GB of available memory. The data sets are entered into a dBase so that they may be further read and processed by most user programs such as Excel.
