Contactor Logic Circuit Replacement In Die casting Machine (LK -12T) Using MITSUBISHI PLC

Abstract

The paper discusses the replacement of Contactor Logic Circuit (CLC) in Die Casting machine (LK-12T) with Mitsubishi PLC and Graphics Operator Terminal (GOT1000) controller. The demand for higher quality, greater efficiency and lesser downtime has lead to the need of automation in industries. Due to automation, the downtime in the industry has reduced significantly and the productivity of industries has increased to a large scale. The previously Contactor Logic Circuit in Die Casting machine is replaced by a PLC(Programmable Logic Controller) so that it has more enhanced capabilities when it comes to speed, storage, programming and power consumption. The improvement in the product quality in Die Casting machine is done by replacing the Contactor Logic Circuit with Mitsubishi FX3U-64M PLC which is being interfaced with the help of Graphics Operator Terminal (GOT1000) controller for easy maintenance. The aim of our system is to reduce the down time of the die casting machine i.e. to increase the productivity of products. Apart from down time, our objective is to improve the quality of the products. Quality defines the speed, precision and efficiency of products. Reduction of the cost of maintenance of the machine is also our prime objective.
