Appendix B TROUBLESHOOTING GUIDE
B.1 MECHANICAL INDICATORS
PROBLEM
POSSIBLE CAUSE
ACTIONS
Pressure
dropping/excessive
pump operation
System leak (either internal
or at Bubbler line
connections)
1) Ensure orifice line is correctly seated and
tightly attached at all connection points. All
fittings should be attached using Teflon tape
to maintain tight seal.
2) Inspect orifice line for splices. Replace
spliced line.
3) If Bubbler line connections are correct, an
internal leak is indicated. Contact FTS Support
to return Bubbler.
Compressor not
running
Insufficient power
1) Ensure Bubbler has a direct power source.
It cannot be fully powered through the
Datalogger’s SDI port (section 2.6.2).
2) Check power connections (including solar
panel, if using).
3) Check battery (replace if necessary).
Incorrect Stage
A) Erroneous offset value
B) Blocked orifice line
1) Set Stage directly by entering the staff
gauge value (if known); or
2) Poll the sensor. Refer to Section 4.6.2.
1) Conduct a purge.
2) Ensure orifice is free from larger
obstructions/blockages.
Slight pause in
bubble release
Measurement being taken
No action required. This is normal operation.
B.2 MEASUREMENT VALUE FAULT INDICATOR
A fault is indicated if The M or M1 command returns a value of -99999.0.
If after 45 seconds of purging, the line cannot be cleared, and the tank pressure is greater than
35 psi, a LINE_HIGH will be indicated in the status screen and the compressor will stop. The M and
M1 commands will continue to be sent but will return values of -99999.0. The unit will continue to
attempt to bubble (the solenoid will continue to open and close) in the event the blockage does get
cleared and normal operations can resume.
Refer to LINE_HIGH Fault in Section B3 for troubleshooting.
