4) NOX Sensor; part #: EMS-5065; 6 month min. re-calibration for accuracy and 2-3
Year Interval change out, or ERROR code Bad NOX 5003 model.
·
NOX Sensors should re-calibrated a min of 6 month intervals. New NOX sensors
require re-calibration as well as NOX accuracy checks.
·
Calibration Bad Nox sensor message is a FALSE error, press Zero to clear!
·
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. Reattach the four pin
connector to the sensor. Attach cover back on the main housing.
5) Water Trap Assembly Filter; part #: EMS-5371; 3-6 month min. Interval
·
Water Trap Assembly filter is a disposable filter, with the sample flow from inside/out so
you will not see contamination. Carbon build up could cause a LOW Flow error. Un-
screw the filter bowl turning clockwise to loosen. Unscrew the filter retainer turning
clockwise, remove the coalescing filter. Install new filter, tighten filter retainer counter-
clockwise, Screw on the filter bowl turning counter clockwise to tighten. NOTE: The air
flow through this filter is from the inside/out, so to inspect the filter contamination, the
coalescing filter must be removed to inspect.
6) General Every Day Operation/Maintenance for Instrument Life. NOTE: Not perform-
ing these daily maintenance items could cause component failures that may not be
covered under Warranty.
·
Turn the 4 or 5 gas on in the morning in display mode and allow the instrument to warm
up and get more stable running several hours before shutting the pumps down. 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 when your ready to use the
analyzer as well as more stable readings.
·
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 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. The model 5003 has a leak check menu screen, go to
this screen first. Plug the inlet quick connector on the analyzer for an internal leak
check.
·
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 sec-
onds.
