The automatic heating regulation is provided by means of a PLC activated by temperature signals given by thermocouples.
The entire regulation system is connected to the PC supervisor.
Supervision is made by means of a IBM PC compatible equipped with BHT programs that ensure the following functions:
• to converse with the PLC and the control system;
• to facilitate the system regulation using a single work station;
• to file different regulation rules (called “recipe”);
• to manage alarm signals and diagnostic system.
