EAGLE 2 Operator’s Manual
Using Setup Mode • 103

50000 ppm CAT
This selection is for users who want their catalytic channel to be configured with
the standard factory settings but would like the gas name to be displayed as
something other than CH
4
so that it doesn’t get confused with other combustible
sensors that might be installed (IR, TC). The LEL is set to 50,000 ppm. If the gas
is configured for this choice, the methane elimination feature is inactive and the
Methane Elimination Mode Screen will not appear in Display Mode. See
“Methane Elimination Mode Screen” on page 44 for a description of the
Methane Elimination Mode Screen. See “Appendix J: Methane Elimination
Mode” for a description of Methane Elimination Mode.
•
10000 ppm - - - *
This selection is a user defined selection. The factory setting is 10000 ppm - - -
*, with the asterisk (*) indicating that it is user defined. If this selection has been
updated in the field, it will appear differently, but the asterisk will always remain
next to the menu item to indicate it is user defined. If you choose the user defined
selection, the unit will prompt you to enter four parameters: a three character gas
name, the LEL value in terms of ppm, the response factor relative to methane,
and the detector voltage. When you configure the gas as the user defined choice,
the methane elimination feature is active and the Methane Elimination Mode
Screen is accessible in Display Mode. See “Methane Elimination Mode Screen”
on page 44 for a description of the Methane Elimination Mode Screen. See
“Appendix J: Methane Elimination Mode” for a description of Methane
Elimination Mode.
5. Use AIR
▲
YES and RANGE
▼
SHIFT to move the cursor next to the desired gas for
the catalytic channel.
6. If you placed the cursor next to one of the pre-defined gases, press and release
POWER ENTER RESET to select the gas and proceed to Step 15.
If you placed the cursor next to the user defined gas with the asterisk (*), press
POWER ENTER RESET and proceed with Step 7.
7. The user defined gas setup screen appears with the first character of the gas name
flashing. The current gas name and range are shown on the top line of the screen.
8. Enter the gas name. Use AIR
▲
YES and RANGE
▼
SHIFT to display the desired
character, then press POWER ENTER RESET to enter the displayed character and
move to the next character. Repeat until all three characters are entered. When the last
character is entered, the ppm ratio value will be flashing.
9. Use AIR
▲
YES and RANGE
▼
SHIFT to display the desired ppm value. This value
is called the ppm ratio and must be the ppm equivalent of the LEL for the gas being
defined. For example, if you are defining propane, the LEL for propane is 21,000
ppm, so you must enter 21000 ppm (2.1% volume).
