Operation Manual SUPREMA
2. System Concept
• Maximum number of switching outputs in the system: 512.
• System operation via a graphic display screen with a resolution of 240 x 64 pixels, cursor
keys and individual function keys.
• System operation optionally via laptop (Windows-oriented user interface).
• Option for connection of an external PC (data evaluation, data display, etc.).
• Key switch connection or password for access control.
• Key switch connection for relay inhibiting.
• Common alarm LEDs for 1
st
to 4
th
alarm, signal failure (sensor), horn, inhibit, power
supply failure.
• Protocol printout of status changes + system operations (standard ASCII, 80 CHR).
• 3 x RS 232 interfaces for data transfer to an industrial PC/laptop/printer.
• RS 232 interfaces are electrically isolated.
• RS 232/RS 485 converters used for longer transmission distances.
• The 8 MRO-Module common alarm relays supplied by the rack power supply unit.
• External relays are supplied with power separately.
2.3 Construction of the Unit
The modules of the SUPREMA are mounted in a rack. For expanded systems, additional
modules can be placed in a second rack or installed on top hat rails in a switch box. Data is
exchanged between the modules over a CAN bus, which makes it possible to transmit data
over distances of up to 1,000 m. For measurement tasks that require redundant signal input
and processing, additional modules can be added at any time to expand the gas warning
system.
The installation site of the modules must be outside Explosion Zones 0, 1, and 2 and be free of
ignitable, explosive, or corrosive gases.
The sensors must have the type of protection against ignition prescribed for the installation
site. The connection between the input module of the SUPREMA and the sensors is established
by a screened remote-measurement cable of the 2-, 3-, 4- or 5-wire type.
The SUPREMA system must be operated at a voltage in the range of: 19.2 VDC to 32 VDC.
For servicing, the sensors can be electrically isolated from the SUPREMA by mechanically
disconnecting the plug-in connection (MAT, MAT-TS modules).
The following block circuit diagram shows the possible layout of a non-redundant system.
