Base3 Detector Personality Module (Dpm) - Siemens Maxum II Service Manual

4. If the analyzer has mechanical regulators, shut off the hydrogen and air supplies to the
detector.
5. Remove the cover and insulation from the old detector. Use caution at this point as the
detector may still be hot.
6. Disconnect the hydrogen and air lines to the detector and the detector vent line from the
back of the detector.
7. Disconnect the column from the detector in the Maxum II oven.
8. Disconnect the light pipe from the side of the analyzer. Remove and discard the brown
Viton O-rings on the light pipe. The new FPD does not require O-rings in this location.
9. Remove the screws from the detector mounting plate and the cover plate on the back of
the mezzanine.
10.Remove the detector from the Maxum II along with its mounting bracket, heater and cover
plate. The heater wiring, glow plug supply wiring and the associated purge tubes need to
taken out as well. Note the wiring connections as you remove them from the DPM.
11.Before installing the new detector, the cover and insulation need to be removed. Replacing
the insulation and cover will be the last step in the installation.
12.Install the FPD II. As you install the detector feed the wiring through the mezzanine and up
to the DPM. Connect the screws on the mounting plate.
13.Attach the mezzanine cover plate.
14.Connect the heater, thermocouple, and glow plug wiring to the DPM.
15.Connect the column inlet, hydrogen and air supplies, detector vent and the light pipe.
16.Replace the insulation and cover on the detector. Restore power to the Maxum II.
17.After the Maxum II has had time to heat up, check the flows and light the flame.

Base3 Detector Personality Module (DPM)

Output signals from any of the detectors connect to each associated Detector Personality
Module (DPM) input. The transfer of detector data is based on the database method. The DPM
digitizes the signal and then passes the data to the SYSCON via an I

CAUTION
Potential burn hazard. Handling hot components may result in personal injury.
Detector may still be hot during removal. Exercise care when handling detector parts.
NOTICE
Sensitive components. Failure to observe proper procedures may damage the equipment.
The photomultiplier in the FPD is sensitive to light. Avoid prolonged exposure of the
multiplier to excessive light, even when powered down. Never subject the light entry
window to a bright light source.
