3-28 | Model 241CE II Hydrocarbon Dewpoint Analyzer
Start-Up and Verication
This section describes equipment and controls on the analyzer that re-
quire adjustments and settings before, during, and after power-up.
Prior to power-up, all local electrical codes must be followed for in-
stalling and starting up electrical equipment in hazardous locations.
Before powering up the analyzer, test the area for explosive gases.
If an explosive gas atmosphere is present, do not apply power to the
analyzer.
Do not apply power to the analyzer if there is damage (scratches,
indentations, or wear) to any flamepath (on the Electronics Enclosure
or Cell assembly). Applying power to an analyzer with a damaged
flamepath is dangerous and could result in serious injury or death,
or serious damage to equipment. See “Examining and Caring for the
Flamepaths” in Chapter 6.
Replace parts immediately if damage or wear is apparent. Contact
AMETEK if there is any doubt about the integrity of any flamepath.
Powering Up the Model 241CE II Analyzer
When the Model 241CE II Analyzer is turned on, the hardware is initial-
ized and the configuration data is retrieved from the EEPROM. This
information is pre-programmed at the factory, according to pre-arranged
customer requirements. The operational data included as part of the con-
figuration are:
• High and Low mirror temperature setpoints.
• Purging time.
• Fast and Slow mirror cooling rates.
• Alarm setpoints.
• System of units for displaying output values (Metric/Imperial).
For complete configuration information, see the “241_Dewpoint Monitor
Data Sheets” in the Documentation Package shipped with the analyzer.
Normal operation begins immediately with the Purging/Hold Stage. The
solenoid valve is opened to start the flow of sample gas into the Measur-
ing Cell. Meanwhile, the signals begin to scroll by on the User Interface
(RUN menu).
