Position: Procon's new EP50 Proweigher batching controller provides customers with a highly versatile and cost effective process instrument which has the additional power to control complete areas of plant, centred around the batching process.
The Controller can operate as a stand alone process batching controller, bag filler or even as a trip amplifier and can be used for up to 16 ingredients and 99 recipes.
In addition to the 16 dual speed ingredient set points, there are 4 level alarms, 8 level trips, 4 process timers and 8 sequence driven outputs.
As well as the primary load cell input, the controller can also handle other analogue process inputs.
The Bcthing Controller may also be equipped with over 60 digital inputs/outputs, providing direct plant control.
The design of the unit, which is based on Procon's extensive experience in process weighing, incorporates the latest customized microelectronics to ensure the highest weighing accuracy, combined with the power required to perform complex process control without the need for special remote programming tools.
Set up can be carried out on site using the Controller's fully programmable high level sequence control language.
Flexible inter-connectivity is assured by the integrated bi-directional serial ports which can be set up by the user for a range of standard protocols, including Modbus and Profibus.
This Proweigher Batching Controller allows easy connection to PLCs and SCADA systems.
The front panel is sealed to IP65 and provides the user with a LED weight display and 2 x 20 character LCD display for operator menu and product data information.
The Proweigher Batching Controller is part of Procon's extensive range of load cells and instrumentation.
The EP50 Proweigher batching controller from Procon Engineering is now available with a stability facility, specifically designed to prevent the costly and time-consuming problems associated with feed or discharge pumps running dry.
With this feature, the batching controller can be configured so that it initiates an alarm when the rate of weight change during feed or discharge cycles falls below a preset lower limit.
This puts the Proweigher Batching Controller into 'hold' mode, signals the pump to stop and warns the operator of a malfunction, thus allowing remedial action to be taken before the pump runs dry and seizes or burns out.
The EP50 is extremely flexible and is designed to be used as a standalone batch or process controller, bag filler, loss in weight or belt weigher controller as well as a multiple trip amplifier.
The standard unit can store 99 recipes with up to 16 ingredients, expandable to an almost infinite number of recipes and ingredients when used with PLCs and Scada systems.
The unit can provide enhanced standard batch logs and incorporates user definable, bidirectional serial ports with a choice of protocols as standard.
Modbus supervisory control also comes as standard which can be converted to integrate with other industry standard bus systems including Profibus and DeviceNet.
Procon has recently installed 17 EP50 based batching control system for Akzo Nobel at its decorative coatings plant.
