FUNCTION

MCON Carbo is a new and advanced controller for the control and regulation of carburizing processes in heat treatment plants. The controller is able to control up to three independent control loops. Next to the C-level, the oven temperature and oil bath temperature can be regulated additionally.. As a graphic recorder, the new controller can record all loops characteristic values.

All commercial thermocouples, lambda- and oxygen probes as well as gas sensors, e.g. CO, CO2, can be connected to the MCON Carbo. To ensure the required redundancy according to CQI9, the controller can detect, evaluate, and process signals of two measuring probes. In addition, the new generation of controllers offers various checking mechanisms and monitoring capabilities.

The carburizing process, with its involved C-level and temperature setpoints, can be controlled at the designated time domains by up to 99 programs with 24 segments and 16 control tracks. The control tracks can also activate digital outputs, once the program has reached the desired segment.

The user can define his own alarm thresholds which do not only control critical values but also activate therefore occupied outputs. Predefined alarms are triggered automatically if unexpected system conditions (reaching soot limit, probe errors, control errors, etc.) occur.

Our MCon Carbo is fully configured with 2 RS485 MODBUS (master and slave) and a TCP / IP Modbus slave interface. An integrated web server allows remote access to all new MESA devices.

User accounts with password protection improve the safety in usage by locking access levels, parameters, and functions depending on user privileges.

Of course, the controller is available with only one or two control loops.
