4) NOX Sensor; part #: EMS-5065; 6 month min. re-calibration for accuracy
and 2-3 Year Interval change out, or ERROR code NOX Z WARN 5002
model.
·
NOX Sensors should re-calibrated a min of 6 month intervals. New NOX sen-
sors require re-calibration as well as NOX accuracy checks.
·
NOX Sensor NOX C WARN model 5002 will appear if the sensor is bad.
·
TOOLS: 2 mm key style allen wrench
·
Remove the 12 #6 button head screws with 2mm allen. Be careful not to strip
allen head when loosening & ONLY FINGER tight when tightening.
·
Remove the cover, NOX located in the back left. Unplug the four pin connector
on the top of the sensor, loosen turning counter clockwise and remove. Install
new sensor, marking install date, turning clockwise into the sensor block. Re-
attach the four pin connector to the sensor. Attach cover back on the main
housing.
5) Water Trap Assembly; part #: EMS-5072; 6-12 month Interval Visual Check.
·
Water Trap Assembly is maintenance free besides a visual check for any carbon
build up. If carbon build up is present, unscrew filter bowl and remove the metal
or sintered bronze filter, soak in hot soapy water, scrub if necessary dry out and
re-install. If water is present in the water trap, plug the inlet of the analyzer with
your thumb and create a vaccum to pull the water out of the filter and into the
drain hose.This can be done every time sampling is done.
6) General Every Day Operation Tips for Instrument Life.
·
Turn the 4 or 5 gas on in the morning in display mode and allow the instrument
to warm up and go into auto shut down mode. This will keep the bench ready for
use when needed, with out having to wait for the instrument to warm up. This will
not damage the unit and help save time.
·
Moisture is your BIGGEST enemy for this instrument life! If any moisture build up
is visible in the analyzer clear hoses, allow the instrument to dry out by running
ambient air through the analyzer continuously for a minimum of 30 minutes or
until NO moisture is present in the hoses.
·
Sample Hose and S.S. probe should be blown out with compressed air at the
end of the day. Moisture build up will leave carbon build up inside the hose and
deteriorate the hose causing leaks. Clean sample hose once or twice a year by
soaking in hot soapy water, blow out with compressed air.
·
Leak Check should be performed after every filter change out to insure no O2
leaks causing invalid gas readings. Plug the inlet quick connector on the ana-
lyzer for an internal leak check. The model 5002 will show LOW FLOW on the
screen and the pumps will shut off, and if the pumps stay off 30 seconds there
are no leaks.
·
Leak Check your sample hose and probe every filter change out only after you
have verified no internal instrument leaks. Connect the sample hose to the
analyzer and plug the end of the probe with the red/black plastic cap supplied by
EMS. The same low flow codes will come up as described above and the low
flow should hold for 30 seconds.
