water ingress resistance of the CNI2 will have been compro
mised, which reduces the
overall safety and reliability levels.
3)
If the enclosure is opened for service reasons, check for any evidence of moisture
accumulation, mold, or cable corrosion. Inspect the enclosure gasket for evidence of
small cracks, which wo
uld indicate that it should be replaced.
It is normal however that a
gasket will have a slight indent mark due to the compression from the lid.
Insects will
normally not be an issue so long as the cable glands were properly tightened during the
initial i
nstall. Performing this periodic service step increases potential service life,
reliability, and maintains hazardous area safety.
4)
Where the CNI2 has the external antenna connection option, this should be inspected
for corrosion. Normally it is best poli
cy to completely seal the connector area with
a
suitable
sealant.
5)
Cleaning / decontamination of the enclosure
’s
exterior is normally not necessary, except
to address obvious issues such as a bird
or hornet
nest
s
atop the unit. If it is desired to
clean th
e surface for better label visibility, then a cloth heavily dampened with water or
a
spray cleaner
such as
Clorox Formula 409 will work.
WARNING
–
Explosion Hazard
The plastic enclosure
’s
surfaces are potential sources for static charge accumulation
w
hen rubbed with a dry cloth. This could result in static discharge, which would then
lead to hazardous gas ignition / explosion.
Always use a damp cloth when cleaning the outside surface of a CNI2 enclosure.
Additional service is normally not required,
unless it becomes necessary to swap out a CNI2 or
diagnose
problems
. Precautionary guidelines when using multi
-
meters and other diagnostic
equipment while inside a potential hazardous gas environment apply here.
WARNING
–
Explosion Hazard
Do not ma
ke or break connections while
the
circuit is alive unless
you are in an
area
known to be non
-
hazardous. This includes both field wiring connections and battery
pack replacement.
If there are any operational problems directly related to the electronics o
f the CNI2, then it is
often times more convenient to swap the unit out with a spare and then later make a
determination in the repair shop as to whether it should be returned to
Honeywell
for service.
