Dedoussis Engineering LTD e-Batch Concrete INTRODUCTION This tool is designed to support the technician in the installation or maintenance works of an e-batch system. The communication between this program and a PLC unit is based on Ethernet utilizing the Internet protocol suite (TCP/IP and UDP telegrams) so the members should be on the same network and share same network parameters (e.g.

Dedoussis Engineering LTD e-Batch Concrete 2.4.1 – Calibration by weight This option gives us the freedom of using a calibration weight (>30% F.S.D.) to calibrate our scale. The program in two steps asks for empty scale, and then loaded scale and calculates the gain of the system.

Dedoussis Engineering LTD e-Batch Concrete 2.4.2 – Calibration by mV/V This type of calibration is mostly used because of the size of weights needed for batching plants and also because of the stable and accurate manufacturing and detailed certificates of modern load cells.

Dedoussis Engineering LTD e-Batch Concrete considered at the time of sizing the load cells and the scale full capacity. After pressing the ‘CALIBRATE’ button the program asks for empty scale, and then finalizes the system. It is important that the ‘no motion range’ and the stabilization time take care of possible vibration on the scale to avoid a ‘not stable’...

Dedoussis Engineering LTD e-Batch Concrete As we see after pressing the ‘CLOSE’ button, our scale shows 0.0 weight and the TAC number is incremented since the calibration data have changed. - 14 -...

Dedoussis Engineering LTD e-Batch Concrete 2.4.3 – The Traceable Access Code (TAC ) The system has provide a guard against improper access of the calibration commands. The LDU xx.1 digitizer features the Traceable Access Code. or TAC method of controlling the access to the calibration commands group.

Dedoussis Engineering LTD e-Batch Concrete countries will comply with either the relevant EN’s (Euro Norms) or the relevant OIML (Organisation Internationale de Metrologie Legale) recommendations. The LDU xx.x has been approved as a component for use in weighing systems according to OIML recommendation R76, the highest performance level approved being Class III, 3000 division.
