6-2 Omni FTIR Multi Gas CEMS Instruction Manual
Instrument Zero Air = 6 LPM when in instrument zero mode
●
Flowback = 3 LPM when in instrument zero mode
●
Probe Zero Cal Gas = 6 LPM when in probe zero mode
●
Probe Span Cal Gas = 6 LPM when in probe span mode
●
Probe Spike Cal Gas = ~0.5 LPM when in probe spike mode
●
Temperatures in IMACC software:
●
Heated sample line = 185 Deg. C
●
Heated pump/valve assembly = 180 Deg. C (after 30 minute
●
ramp-up)
FTIR Sample Cell = 180 Deg. C (after 2 hour ramp-up)
●
Internal Heated Lines (if installed) = 180 Deg. C
●
LED indicators on FTIR:
●
"Power" should be on continuously, if not check circuit breaker
●
and power supply
"Laser" should be on continuously, if not check laser assembly
●
"Source" should be on continuously, if not check source
●
"Scan" should be flashing during normal operation, if not check
●
if IMACC software is running
Readings in IMACC software:
●
FTIR Vmax > 0.9
●
FTIR Vmin < 0.0
●
If voltages are too small, check source, beamsplitter, detector,
●
cell windows and cell mirrors.
Cell Pressure = <40 mmHg less than ambient pressure during
●
sample mode
The following outline addresses possible instrument and alarm problems
and proposes checks and possible troubleshooting solutions.
