Decommissioning
9.1
Safety measures before decommissioning
9.1.1
Protection of external components
▸
Consider and protect connected external components.
▸
Check if any automatic emergency measures could be triggered when you decommis-
sion the analyzer. Observe the switching logic of the PowerCEMS100 analysis system as
well as the gas analyzers.
▸
Prepare connected software systems for decommissioning.
This helps to prevent possible malfunction messages.
▸
Observe electrical safety rules.
9.1.2
Completely remove toxic/humid sample gases
▸
Stop sample gas feed.
▸
Switch off sample gas pumps.
▸
Prior to decommissioning, all sample gas components have to be thoroughly purged with
a dry, neutral gas.
▸
Purging with ambient air can also be performed after considering and checking the
application and ambient conditions.
For purging, suction in the ambient air via the sample gas probe for several minutes.
▸
Stop the purge gas feed and close off all gas connections of the PowerCEMS100
analysis system or close off the relevant valves in the purged gas path.
Refer to the relevant Operating Instructions for further information on the
switching logic of the gas analyzers.
Note
Activate status output “Maintenance” on the gas analyzer. The sample gas
pumps are switched off.
DANGER
SAMPLE GASES DETRIMENTAL TO HEALTH OR TOXIC
Serious injuries of the respiratory system or death.
▸
Wear suitable respiratory protection for all work on the gas lines.
▸
Prior to decommissioning, adequately purge the measuring system
with neutral gas (e.g. nitrogen N
2
).
Note
Consider the maximum allowable sample gas pressure of the analyzer when
purging with a neutral gas.
Refer to the Operating Instructions/Technical Data of the relevant analyzer for
the maximum allowable sample gas pressure.
Refer to the Operating Instructions of the respective analyzer for details on
operation and menu functions.
