GAA610-M ADVANCED EMISSION GAS MONITORING SYSTEM | OI/GAA610-M-EN REV. B
Working with hazardous gases
Some gas components whose concentration is measured with
the analyzer system are hazardous to health.
For this reason, the sample gas must under no circumstances be
allowed to escape uncontrolled from the sample gas path in
either the measurement mode or when performing maintenance.
•
The analyzer system must be checked for leaks regularly.
•
The measured stack gas must be returned to the process or
discharged in a suitable exhaust duct.
•
Ensure adequate ventilation of the room in which the
analyzer system is installed.
•
The legal requirements for the maximum work place limit
values of the measurement and test gases must be observed.
Protective lead connection
The protective lead (ground) should be attached to the
protective lead connector before any other connection is made.
Risks of a disconnected protective lead
The device can be hazardous if the protective lead is interrupted
inside or outside the device or if the protective lead is
disconnected.
Risks involved in opening the covers
Current-bearing components can be exposed when the covers or
parts are removed, even if this can be done without tools.
Current can be present at some connection points.
When safe operation can no longer be assured
If it is apparent that safe operation is no longer possible, the
device should be taken out of operation and secured against
unauthorized use.
The possibility of safe operation is excluded:
•
If the device is visibly damaged,
•
If the device no longer operates,
•
After prolonged storage under adverse conditions,
•
After severe transport stresses.
Risks involved in opening the gas paths
Do not open any gas paths in the analyzer system or in the
integrated analyzers.
Doing so will damage gas path seal integrity.
If system-internal gas paths are opened, a seal integrity check
must be performed with a leak detector (thermal conductivity)
when the device is reassembled.
