Sampler Warning Message Troubleshooting
SYMPTOM FAULT ACTION / COMMENTS
1. Display shows:
FAULT
PROBE OPEN CCT
and sample shot cycle aborts
Notes:

This message will only appear briefly
if a program is not in progress when
the fault occurs

This fault will not cause the program
to abort. It will, however, prevent a
program being initiated
a. Chamber not fitted
b. One or more contact springs
in front panel sample
chamber assembly recess
not connecting to its
respective electrode
c.
Electronic fault
a. Fit chamber
b. Clean tops of electrodes
where contact is made with
contact springs. See
Cleaning Sample Tract /
Stainless Steel Electrodes
earlier in this Section
N.B. Contacts springs should
project about 6mm from their
location holes
c. Contact supplier for service
advice
2. Display shows
FAULT - CLEAN
CHAMBER TOP
and sample shot cycle aborts
Notes:

This message will only appear briefly
if a program is not in progress when
the fault occurs

This fault will not cause the program
to abort. It will, however, prevent a
program being initiated
a. A conductive path is present
between the ‘common’
central Level Sensing Probe
and either one or both of the
other two Level Sensing
Probes prior to commencing
the sample intake phase.
This is probably due to
effluent build up resulting
from splashing during the
intake phase
b. Electronic fault
a. Clean Chamber Top. See
Cleaning Sample Tract /
Stainless Steel Electrodes
earlier in this Section
Review Sampler installation
to ensure splashing does not
occur during the intake
phase. See Installation
Section of this User Guide
b. Contact supplier for service
advice
3. Display shows:
FAULT
GUARD PROBE HIT
but sample shot cycle continues
normally
Notes:

This message will only appear briefly
if a program is not in progress when
the fault occurs

This fault will not cause the program
to abort. It will, however, prevent a
program being initiated
a. Sample induction phase is
terminated by short guard
probe because long probes
have become insulated due
to contamination build-up
b. Sample induction phase is
terminated by short guard
probe because wastewater is
entering the Sample
Chamber in a turbulent
manner causing random
triggering due to splashing
a. Clean Level Sensing Probes
b. Clean Chamber Top. See
Cleaning Sample Tract /
Stainless Steel Electrodes
earlier in this Section
