Table 16-1 Diagnosing Problems - HAPSITE
Symptom Cause Remedy
1. Filament will not turn on
(Unable to turn on
filament error! on user
interface.) 1a. Remove ion source and check
to see if filament has opened. 1a. If opened, replace ion source
(see
section 16.8, Replacing the
Ionizer of the Mass Spectrometer,
on page 16-35
), otherwise contact
Customer Support (see Chapter
17 ).
2. Filament shut off. (Over
pressure fault.) 2a. System shuts down filament if
pressure spikes. An old ion pump
will "burp" N2 and Ar which can
cause the system to shut down. 2a. Replace ion pump. Contact
Customer Support (see
Chapter
17 ).
2b. System has an air leak. Turn
off carrier gas and check to see if
mass 32 is relatively large (10 to
20% of peak 28) 2b. Contact customer support (see
Chapter 17 ).
2c. Turbo/molecular drag pump or
diaphragm backing pump may
need servicing. 2c. Check turbo speed in the
Service Module program. Service
pumps if speed is less then 1480
Hz, and there are no air leaks.
2d. NEG. is depleted. 2d. Replace NEG. pump. Using
INFICON part # 930-425-P1. See
section 16.7 on page 16-17 .
3. Electron Multiplier
fault. message at user
interface. 3a. High pressure in vacuum
system caused by the failure of the
ion pump to pump Ar with a NEG
installed. 3a. Contact Customer Support
(see
Chapter 17 ).
3b. Short in electron multiplier, or
fault in high voltage power supply 3b. Contact Customer Support
(see
Chapter 17 ).
4. Poor sensitivity in tune. 4a. Ion source has degraded. 4a. Replace ion Source using
INFICON part # 930-205-G1. See
section 16.8, Replacing the Ionizer
of the Mass Spectrometer, on
page 16-35
in this manual.
4b. Quadrupole/EM assembly has
degraded. 4b. Contact Customer Support
(see
Chapter 17 ).
