Type of Alarm
Cause
Detect and Repair
Alarm 1:
“The selected
sampling volume
has not been
reached 3 times
in a row. Program has
been stopped”
1. The pump or membrane
is broken.
1. Disconnect the outlet tubing from MFC
2. Check whether the pump is sucking properly
or not.
3. Exchange the pump if it sucks only weakly.
2. The rotary valve VE 1 is
not switching properly
and stays in a middle
position when switched.
1. Check the rotary valve VE1.
2. If necessary loosen the rotor until the valve is
switching properly.
3. Tighten it again as described in chapter 13.3.11.
3. The sample way is
permanently blocked
because the sample line
is blocked.
1. Disconnect the tubing from the sample inlet at
the back of the analyzer.
2. Start sampling and check the sample flow.
Result 3:
If it is ok now, then the fault is located in the sample
line:
Clean the sample line and remove any particles
which are blocking it.
4. The sample way is
permanently blocked
because of the MFC
If the flow is still too small (as described above in
step 1.-2.), then continue as follows:
3. Disconnect the inlet tubing from the MFC.
4. Start the sampling
5. Check if the sample flow is ok now.
Result 4 :
If the sample is still too low, the MFC has to be
maintained by the manufacturer AMA Instruments.
5. The sample way is
permanently blocked
because the in-line filter
is almost blocked.
If the flow is ok after disconnecting the tubing like
described above in step 1.-5. continue as follows:
6. Connect the inlet tubing of the MFC again
7. Disconnect the inlet tubing from the in-line filter.
8. Start sampling and check if the sample flow is ok.
Result 5:
If the sample is too small, the in-line filter has to be
replaced.
