Chapter 1 Startup
Restart
Initial startup of the analyzer system should be performed by trained personnel of
the manufacturer or the supplier.
Restart Perform the following steps when restarting the analyzer system e.g. after
maintenance or a facility shutdown.
Activating the
Instrument Air Supply

Set the initial pressure (p
e
= 5–7 bar).

Check the moisture indicator in the air purifier: green = OK, yellow = not OK.

Activate the instrument air supply to the FTIR spectrometer at the earliest 1 hour
after activating the power supply. This will ensure the air is sufficiently dry.
Activating the
Power Supply

Make sure all circuit breakers (fuses) are deactivated.

Turn on the main switch.

Activate the circuit breakers (fuses) – starting with those for the FTIR
spectrometer.
Connecting the
Filtered Air

Check the filtered spectrometer purge air flow rate and set it to approx. 200 l/hr
if necessary.
Checking the
Temperature

Check the temperature of the heated components (gas sampling probe, filter
unit and sample gas line; desired value 180 °C).
Starting the
VOC Analyzer

Start the VOC analyzer following the instructions and information in the AO2000-
MultiFID14 Start-up and Maintenance Manual (Publication No. 41/24-105 EN).
Warm-Up Phase The warm-up phase takes approx. 3 hours.
Calibration

Start the manual zero correction (see section “FTIR Spectrometer Zero
Calibration”, page 33).
