Filament Trip/Overpressure and LEDs
1.
Check the LEDs on the back of the Dymaxion. Filament status can be
determined by the color of the lights. Refer to the previous section for
LED details.
2.
Make sure the filament is turned on by checking the “Light Bulb” icon
on the toolbar in the Dycor System 2000 software to make sure it
is yellow (ON). Check the filament status and emission current by
accessing the Edit menu on the toolbar and selecting “Add Display.”
Click on “Head Status.”
3.
Restart the entire system and recheck the filament status and emis-
sion current.
4.
If there is no filament current, turn off the instrument, pull the Dymax-
ion from the analyzer head and check the continuity between Pins 3
and 8.
5.
If the filament is burned out (LED is red), open the vacuum system and
replace the filament assembly.
If the filament checks out OK, do the following:
•
Check the LEDs on the back of the Dymaxion.
• If the LEDs are green and there is no overpressure and the filament
has not tripped, call the factory for assistance.
Caution Against Swapping Components
The Dycor System 2000 software has been programmed to accept the combina-
tion of a sensor probe and Dymaxion with different configurations and to auto-
matically set a default configuration for the combined components. However,
when mixing components with different configurations such as a multiplier Dy-
maxion and a Faraday cup quadrupole head, the default configuration is always
the Faraday cup configuration.
• Do not mix components that come from different Dycor models.
