HEAT CONTROL ELECTRONIC SYSTEMS

An electrical panel controls the heat regulator functions and is fitted to each machine. The panel is manufactured in compliance to current regulations and is protected to IP55, ensuring its reliability in environments where fine dust is present as is normally the case in foundries. Operation is controlled in one of two main ways:

1) Standard electro-mechanical

2) PLC

Standard electro-mechanical logic employs relays, timers and electronic instruments for heat control. Interface with the die can be done with a power line 4-20mA (or 0-10V as an option) to transmit and set temperature and with HARTING connectors to transmit alarms, commands, start-stop, etc.

As an alternative, it is possible to control the working logic using PLC technology. The panel usually employed is the Siemens S7-200 (or others on demand) expandable by the addition of further analogical card thermocouples as requested by the user. Data are shown on a 4 line by 20 digit display designed for foundry applications or with any other display requested by the user. Die data interface is done by adding further Profibus or Ethernet Profinet modules as requested by the user.
