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
6. The sample way is
permanently blocked
because the enrich-
ment tube is blocked.
If the flow is ok after disconnecting the tubing like
(described above in the steps 6.-8.) continue as
follows:
9. Connect the inlet tubing of the filter again.
10. Disconnect the inlet tubing of the enrichment tube.
(The tubing which is coated with Teflon hose and
directed to the right side of the analyzer).
11. Start sampling and check if the sample flow is ok.
Result 6: If the sample flow is still too small, replace the
enrichment tube.
7. The sample way is
permanently blocked
because the inlet
tubing of the enrich-
ment tube is blocked
If the sample flow described in step 11 is ok, then
continue as follows:
12. Blow with compressed air into the disconnected
tubing.
Result 7: This should clean the tubing.
If you get this problem with the blocked gas line again:
13. Connect a filter to the sample inlet to avoid it.
Alarm 2:
“The carrier gas
pressure is below
minimum! The
program has stopped”
The carrier gas bottle is
empty.
1. Exchange the carrier gas cylinder.
Alarm 3:
“The PID lamp is off.
The program has
stopped”
1. The lifetime cycle
of the UV lamp has
expired.
1. The PID lamp has to be exchanged.
2. The PID lamp is on
but the signal is still
below 100 mV.
1. Disconnect the PID power cable (red/blue) while
analyzer is running.
2. Check if the detector signal changes.
3. If yes, adjust the detector signal on the detector
amplifier as described in chapter 13.3.5.
Result: The signal in the main menu has to be
> 100 mV when the PID lamp is on.
When the PID lamp is off, the signal has to be
< 100 mV.
