Replacing The Pmt, Hvps Or Tec - Teledyne T200 User Manual

REPLACING THE PMT, HVPS OR TEC

The photo multiplier tube (PMT) should last for the lifetime of the analyzer, however, the
high voltage power supply (HVPS) or the thermo-electric cooler (TEC) components may
fail. Replacing any of these components requires opening the sensor module. This is a
delicate assembly and it is recommend that you ensure the PMT, HVPS or TEC modules
are, indeed, faulty before unnecessarily opening of the module.
1. Turn OFF the analyzer and disconnect the power cord.
2. Remove the cover.
3. Disconnect all pneumatic and electrical connections from the sensor assembly.
4. Remove the sensor assembly.
5. If the TEC is to be replaced, remove the reaction cell assembly at this point by
unscrewing two holding screws.

CAUTION – QUALIFIED PERSONNEL
While the PMT or HVPS can be removed through the front
panel without un-mounting the entire sensor module, we
recommend turning off the instrument, opening its top cover
and removing the entire assembly so that further repairs can
be carried out at an anti-ESD workstation.
Follow the guidelines for preventing electrostatic damage to
electronic components, defined in the manual, Fundamentals
of ESD, PN 04786, which can be downloaded from our website
at http://www.teledyne-api.com
Manuals in the Special Manuals section..
This is necessary only if the repair being performed involves removing the
PMT cold block.
