2-10 Omni FTIR Multi Gas CEMS Instruction Manual

Analog

The system has the option to output up to eleven analog 4-20 ma output
signals. The corresponding terminals on the X1 analog output terminal
block are listed in Appendix C,
FTIR Multi Gas
installation to match the facility's analog data system.

Digital

The system has a pre-configured 'Temperature Alarm' output located on
terminals 21 & 22 of terminal block X2. The terminals have an identical
output. 'High' indicates a low-temperature alarm
See the following for system startup.
Note The initial startup of the FTIR Multi-Gas CEMS should be
performed by the service department of Thermo Fisher Scientific.
CAUTION Sample gas should not be introduced to the cell until the cell has
reached 185 °C. Before air pressure is applied to the system ensure that the
system is in fail safe mode. Disconnect the alarm connection from
terminals 1 and 2 on rear terminal block X3
the system in fail safe mode with sample valve closed and system zero valve
open. ▲
Switch the Measurement/Maintenance switch on the front of the system
rack to the Maintenance position.
Use the following sequence to turn power ON to the system components.
Ensure that the main power connections are made to the system with the
circuit breakers OFF.
Once the main power connections are made, turn on the Main Power
circuit breaker on the breaker panel. Then turn ON the circuit breakers:
Air Purifier, 24VDC, Temp Control, Probe, FTIR, PC/Console.
Check FTIR Unit: The scan, laser and source LEDs light for a few seconds
while the internal diagnostic routines run. Upon successful completion of
the diagnostic tests, the LEDs indicate instrument status. The 'Scan' light
should blink intermittently in normal operation once the PC has booted
and the IMACC FSS software is running; the other lights should be steady.
