supply at the external stopcock.
3 Switch the MCS100FT to purge mode (menu: MCS100FT/Maintenance/Operation
Mode Switch
p. 69, §5.7.9.1)
4 Run the measuring system in this condition for at least 15 minutes.
5 Set the device switch to the “OFF” position.
Caution: Do not switch off the instrument air
6.2 Shutting down
Switch the MCS100FT off (
p. 84, §6.1).
● The shutdown of the MCS100FT may be performed by trained personnel only.
1 Make sure no more flue gas can be suctioned in.
2 Make sure the sampling probe cannot get soiled (for example, pull the probe tube off).
3 Shut instrument air off.
4 Switch off all fuses in the MCS100FT (
p. 89, §7.2).
5 Disconnect all MCS100FT poles from the mains.
6 Purge all lines and valves carrying sample gas with inert gas.
7 Close gas inlets and outlets off airtight.
6.3 Transport
The MCS100FT contains subassemblies requiring transport safety devices.
● Preparation for transport may be performed by trained personnel only.
6.4 Storage
Recommendation: Store the MCS100FT in dry conditions whenever possible.
Moisture in the interferometer causes damage.
● With the power switched off, the sample gas path and the interferome-
ter are automatically purged with instrument air.
Continue to ensure the quality of the instrument air (specification
p. 101).
The thermostatic control of the sampling probe is switched off.
Ensure the sampling probe will not become soiled.
Moisture in the interferometer causes damage.
Check the drying agent cartridge monthly even after shutting down (
p. 90,
§7.2.3).
Moisture in the interferometer causes damage.
