MAINTENANCE
IMPORTANT
Periodic flamepath inspections are not
recommended, since the product is not intended
to be serviced and provides proper ingress
protection to eliminate potential deterioration of the
amepaths.
WARNING
The sensor module (“front” half of the detector)
contains no user serviceable components
and should never be opened. The terminal
compartment is the only part of the enclosure that
should be opened by the user in the eld.
NOTE
Refer to the X3302 Safety manual (95-8582) for
specific requirements and recommendations
applicable to the proper installation, operation,
and maintenance of all SIL-Certified X3302
Flame Detectors.
To maintain maximum sensitivity and false alarm
resistance, the viewing windows of the X3302 must be
kept relatively clean. Refer to the following procedure for
cleaning instructions.
CLEANING PROCEDURE
CAUTION
Disable any extinguishing equipment that is
connected to the unit to prevent unwanted
actuation.
To clean the windows and o
i
plate, use the window
cleaner (p/n 001680-001) and a soft cloth, cotton swab,
or tissue and refer to the following procedure.
1. Disable any extinguishing equipment that is
connected to the unit.
2. Since the X3302 is less affected by contamination
than other detectors, removal of the
o
i
plate is
needed only under extreme conditions. In addition,
it is not necessary to achieve perfect cleanliness,
because IR is not significantly absorbed by slight
films of oil and/or salt. If a fault condition is still
indicated after cleaning, remove and clean the o
i
plate using the o
i
Plate Removal and Replacement
procedure.
3. In all environments, clean all three viewing windows
and reflector surfaces thoroughly. Use a cotton
swab and the Det-Tronics window cleaning solution.
Use Isopropyl alcohol for contaminations that the
Det-Tronics window cleaning solution can not
remove.
IMPORTANT
When used in extreme environments, the reective
surface of the detector o
i
plate may eventually
deteriorate, resulting in reoccurring o
i
faults and
the need for o
i
plate replacement.

i
PLATE REMOVAL AND REPLACEMENT
1. Disable any extinguishing equipment that is
connected to the unit.
2. Loosen the two captive screws, then grasp the o
i
plate by the visor and remove it from the detector.
See Figure 18.
3. Install the new (or cleaned) o
i
plate.
NOTE
When installing the stainless steel plate, ensure
that the gasket is present and correctly seated to
prevent moisture or contaminants from penetrating
behind the plate. To ensure even seating, tighten
both screws equally.
4. Recalibrate the detector's o
i
system. Refer to the
Inspector Monitor manual (95-8581) for instructions
regarding
o
i
plate replacement and o
i
system
recalibration.
CAUTION
Do not replace the o
i
reector plate without also
recalibrating the o
i
system.
Recalibration of the o
i
system requires the use of the
Inspector Connector Cable and Inspector Monitor
Software. These two items are included in the o
i
replacement kit, or they can be purchased separately.
See Ordering Information for details.
