ADJUSTING
8.3
Adjustment procedure
There are two procedures for adjusting the PowerCEMS100:
●
Analyzer adjustment (automatic test gas feed)
●
Probe adjustment
Different test gas paths are used for the procedures.
▸
Analyzer adjustment - the test gas is fed directly to the analyzer.
▸
Probe adjustment - the test gas is fed into the analyzer via the probe.
Select the respective procedure via the key switch on the system cabinet door.
During adjustment, the analyzer independently switches to the correct test gas valve. The
available test gases have to be entered in the analyzer first (see Operating Instructions
BCU).
8.4
Test gas pressure
The test gas pressure for both adjustment procedures is set to:
▸
1.3 bar for all test gases.
Setting is done via the pressure control valve.
8.5
Flow rate values
The flow rate values for both procedures differ as follows:
▸
Analyzer adjustment: 60 Nl/h
Automatic monitoring by the analyzer.
▸
Probe adjustment: > 250 Nl/h
Visual monitoring on the flowmeter.
Setting the flow rate value for external pump via:
●
Bypass needle valve
●
Bypass valve
Setting the flow rate value for internal analyzer pump via:
●
Needle valve on the flowmeter of the sample gas cooler
8.6
Adjustment abort
An adjustment abort is either performed:
▸
automatically
or
▸
manually on the analyzer
Refer to the relevant Technical System Documentation for assignment of the
test gases to the test gas valves.
Note
When the adjustment procedure is aborted, it has to be acknowledged by press-
ing the key switch.
Only then can a new adjustment procedure be started.
