Operation Manual SUPREMA
3. Description of the System
• (A Power-Fail relay is activated when the operating voltage is < 19.2 V or when the status
becomes different from that of the power-on condition) function at the moment not
available.
• System Failure relay is activated when a processor error occurs.
• Euro card with a 96-way connector.
3.6.2 Data Processing/MCP Module (Central Processing Unit)
The data is processed by the Central Processing Unit (MCP Module).
This module controls all system functions. The CPU communicates with the other system
modules over one or more CAN buses. The measurement values are acquired via the MDA
module, and the results of the signal evaluation are output via the MGO module (relay driver
outputs) and the MDO Module (Display).
For higher safety requirements a second additional MCP modules can be integrated into the
system for redundant processing and signal evaluation.
• Monitoring and control of all system functions
• Evaluation of the signals from up to 256 sensors
• Control of up to 512 switching outputs (relay driver outputs)
• Storage of the system parameters.
• Data output (MDO module, Graphic-LCD, MAO module 4 ... 20 mA, MGO module, relays,
printer, etc.)
• Communication with the other modules over the CAN bus
• Storage of the history of the calibration data, measurement values, and temperature
values
• Sensor calibration
• Linearisation of characteristic curves
• System Fail relay activated when a system malfunction occurs
• Euro card with a 96-way connector
3.6.3 Display + Operation/MDO Module (Display + Operating Unit)
The Display + Operation Unit (MDO module) is used to display information and for entering
commands by hand.
The system is operated from the MDO module; status messages are displayed (common
alarm LEDs) and alarm messages are shown in plain text. The system is operated with cursor
keys in conjunction with a Windows like user interface (configuration, performance of calibrations,
etc.).
• Graphic display (240 x 64 pixels) with backlit LCD screen
• System operated from a keypad with 4 cursor keys, ESC and ENTER
• Individual function keys for horn acknowledgement and alarm reset
• Plain text messages for alarms and malfunctions at the sensors
• Graphic display of alarm and failure states (”LED field”)
• Bar graphs of the measurement values
