Pre-amplifier Assembly Removal and Replacement
In the event the sulfur or nitrogen detector pre-amplifier needs replacement, the following steps should be
taken.
1. Turn the power switch to the OFF position and remove the power cord from the detector module.
ELECTROCUTION HAZARD!
DEATH OR SERIOUS INJURY WILL OCCUR IF NOT AVOIDED!
An electrocution hazard exists because severe electrical shock hazards exist
when working around the high-voltage and/or 115/230 VAC components while
power is applied.
HOW TO PROCEED: Avoid hazard by turning off the unit with the ON/OFF
switch and remove the power connection or power cord from the unit to the
power source. Also, follow any required lock-out/tag-out procedures your
company policy requires.
To prevent electrical shock hazard DO NOT operate this equipment in rain or
wet conditions.
2. Use the Sulfur Detector Removal and Replacement procedure, previous section, this chapter, to
remove the detector.
3. Unscrew the preamplifier assembly from the PMT housing.
1. The PMT is extremely light sensitive. All operations involving exposure of the PMT should be conducted in
darkness or in a very low light environment.
2. Make sure that all interconnections are properly installed. Improper connections may cause damage to system
components.
