In addition to start-up tests, errors and warnings, there are several other things
that can cause problems with the NOA or applications (gas measurements. liquid
measurements using the purge vessel, etc.). The first step in troubleshooting is to
isolate the cause of the problem to either the sample inlet system or the
chemiluminescence detector. A list of possible problems with the
chemiluminescence detector appears below. If the problem is not listed below or
assistance is needed, contact Sievers.
No Power to NOA
When the main power switch is turned on, if there is no power to the analyzer, as
indicated by the absence of backlighting or characters on the front panel display
and the cooler and back panel fans are not operating, then the problem is most
likely a blown fuse. The main fuse for the NOA is located in the power entry
module at the rear of the NOA. Remove the power cord from the analyzer to open
the power entry module. To check the main fuse on the NOA:
•
Remove the power cord from the analyzer.
•
Open the power entry module by inserting a small screwdriver behind the slot
at the top of the power entry module, and lifting the cover on the power entry
module back away from the NOA back panel.
•
Pull the red fuse holder out of the power entry module. The holder contains
two fuses.
•
Remove the fuses from the holder. Use an ohm meter to test the resistance of
each fuse. If a fuse is blown, then the resistance will be infinite.
•
If a fuse is blown, replace it with one of identical type and current rating.
Refer to the System Specification section of this manual for a listing of fuse
types and ratings appropriate the NOA 280i.
•
If the fuse is OK, replace the fuse, reinstall the fuse holder in the power entry
module and replace the lid on the power entry module. Contact Sievers for
additional instructions.
