Multicomponent dispenser MKD

Multicomponent dispenser MKD – allows you to automate dosing processes and organize accounting of the consumption of dosed materials.

The MKD control cabinet is a device based on the KV4 Weight Indicator. It has inputs for connecting load cells, damper position sensors and additional controls. Up to ten different actuators can be connected to it and controlled according to a programmed algorithm. The main feature of this product is the ability to quickly reprogram the dosing algorithm and the ability to exchange information with a personal computer via the RS-232 or RS-485 interface.

The control cabinet is wall-mounted with protection degree IP54, the indicator panel and the main controls are located on the front side. The appearance of the control cabinet is shown in Figure 1.

Rice. 1 MKD control cabinet

The KV4 weight indicator, which is part of the MKD control cabinet, is equipped with a two-line backlit liquid crystal display, which displays in dosing mode:

• prescription number (for example, Rec4);
• number of doses used (for example, 1234d);
• current dosing step (for example, w0, i.e. the letter “w” and the step number);
• dispenser state(o—stopped, p—working, h—completion, p—pause);
• current component (for example k1);
• the weight of the current component or the total current weight.

The KV4 terminal can exchange data with a top-level automated control system (ACS) or with a personal computer via RS-232 or RS-485 protocol. When using the RS-485 protocol, it is possible to connect up to 31 devices to a computer simultaneously and create a network.
