1-6 Omni FTIR Multi Gas CEMS Instruction Manual
Data
The system provides several methods for establishing data communication
with a DCS/PLC including:
Modbus protocol (Ethernet or serial)
●
Analog output connections
●
Digital I/O connections
●
Typical communications functions provided by the FTIR Multi-Gas
CEMS include:
Concentration readings
●
System status or alarms (calibration checks, blowback, etc.)
●
There are six gas flow modes: sample mode, blowback, instrument
background scan and flowback, check zero, check spike and check span in
Flow
this FTIR CEMS system. Each of them can be controlled either by the
system operation software, or by the user via PLC. A detailed description is
given in Chapter 7,
The system is powered by a single phase 220-240 VAC 50/60 Hz 60 Amp
service. This is fed to a rack-mounted circuit breaker assembly with a main
breaker plus breakers for the following system components:
FTIR
●
PC with console
●
FTIR purge gas generator
●
24 VDC power supply
●
Probe
●
Temperature controller
