Threshold control X
– The measurement of the X parameter
is higher than the threshold value.
– Compare the measurement of the X
parameter with the threshold value
programmed in the “Configuration /
Limits and Relays” menu.
Threshold control
– The measurement is higher than the
threshold value and the analyzer is in
zero mode.
– In the “Configuration / Limits and
Relays” menu, set the parameter with
a threshold value on the Zero relay.
– The problem is located in the H
2
O
channel. The analyzer works with a
SEC probe.
– Problem with drying efficiency on the
SEC probe. Check the following
points:
–
A: Check the pressure of the
compressed air (4 bars) and the
efficiency of the ejector of the SEC
probe.
– Check the flows in the SEC probe.
– B: Check the Silicagel. A green
colour indicates a fault in the MDS
dryer.
– C: change the Perma-Pure dryers.
– The analyzer works with a dilution
module. The problem is located in the
H
2
O or CO
2
channel.
– The threshold on H
2
O or CO
2
indicates a modification in the dilution
coefficient.
– Check the following points:
– A: Check the excess flow on the
flowmeter of the dilution module.
–
B: dismount and clean the dilution
module. Take good note of the
restrictors’ location .
– Change the O-ring seals.
– Control the rate of dilution by making
a calibration.
