Detect Mode Troubleshooting
Condition Definition Potential Causes Proposed Action
Leak Alarm
• Gross (3gph) Leak
Alarm
The LS300 has detected
a pressure loss
consistent with a leak of
3gph or greater.
• Monthly or Annual
Precision Test Failed
The LS300 has detected
a pressure loss
consistent with a .2gph
leak (one flash) or a
.1gph leak (two flashes).
• Leak in the pipeline
• Submersible pump check
valve not seating properly
• Leak in the manual
pressure relief (FE Petro
Pump)
• Adjustable Functional
Element not seating
properly/defective. (Red
Jacket)
• Push the Test/Reset button to clear alarm.
Conduct a manual leak test to confirm the line
status. If the LS300 again detects a leak after
three failed test sessions, shut down the line and
troubleshoot the pressure loss.
• Check valve seating area should be clean and free
of debris. Clean area if necessary.
• Verify that the manual pressure relief screw (FE
Petro) is turned clockwise.
• Check sump areas for signs of leakage.
• For further information, see FE Petro Service
Bulletin SB007 STP/IST Static Pressure Testing.
Transducer Not Seen The LS300 cannot
detect the signal coming
from the transducer • Transducer is wired
incorrectly
• Wiring or connections to the
transducer are loose or
broken
• Transducer is defective
• See the LS300 Auto-Learn User’s Guide‘s
Transducer Troubleshooting section for specific
troubleshooting information.
Pipeline Failed to Hold
Pressure After the submersible
pump shut off, pipeline
pressure dropped
immediately to 0 psi. • Large leak in the pipeline
• Check valve removed or
stuck open
• Press Test/Reset button to clear alarm. Conduct a
manual 3gph test and confirm line status.
• Verify that the check valve is installed in the
submersible pump and is seating properly.
• Check sump areas for signs of leakage.
• For further information, see FE Petro Service
Bulletin SB007 STP/IST Static Pressure Testing.
Insufficient Pressure to
Conduct Test Pipeline is not fully
pressurizing when the
submersible pump is
turned on. • Power to submersible is
OFF
• Leak in the pipeline
• Transducer problem
• Verify that there is power to the submersible
pump.
• Check sump areas for signs of a large leak.
• See the LS300 Auto-Learn User’s Guide‘s
Transducer Troubleshooting section for specific
troubleshooting information.
Calibration is Incomplete
The line will not detect
leaks because the line is
not Learned • Learn sequence was not
attempted or was not
completed properly
• See the LS300 Auto-Learn User’s Guide‘s Line
Calibration. Follow the instructions on learning a
line.
