Warning
Device Description Recommended Actions
SN3 Pwr Short Slot 3-Wire sensor malfunction. If a 2-Wire sensor is used on a 3-wire module ensure that the
red / pwr terminal is not used. If a 3-wire sensor is used, disconnect
wires and see if alarm clears. If alarm clears inspect shorts in wiring.
If alarm stays at PWR short replace module. Contact Franklin Fueling
Systems’ Technical Services Dept. for support.
SN3 Sensor On ChannelSN3 Discriminating sensor shows
alarm status.
Inspect location for presence of liquid. In the case of a leak, follow
site policy procedures. If no liquid is present, and alarm still exists,
sensor may be tripped on error. Check wiring continuity from sensor
to console. Test sensor at console, trip sensor on purpose. Verify
console terminal wiring. If issue still exists, inspect wiring to probe. If
the condition still exists, contact Franklin Fueling Systems’ Technical
Services for support.
SN3 Sump Full ChannelSN3 3-wire sensor detected sump full
of liquid.
Inspect location for presence of liquid. In the case of a leak, follow
site policy procedures. If in alarm with no liquid is present, sensor
may be tripped on error. Check wiring continuity from sensor to
console.
SN3 Sync Error ChannelSN3 3-wire sensor data signals not in
sync with module.
Verify correct wiring and re-make the connections. Verify sensor type.
SN3 Vapor ChannelSN3 3-wire discriminate sensor
detecting vapors at location.
Visually inspect area for product presence. Verify the vapor level has
been calibrated correctly.
SN3 Water ChannelSN3 3-wire discriminate sensor
detecting water at location.
Visually inspect area for water presence.
Line Leak Detector (LLD) Alarms
Displayed Alarm /
Warning
Device Description Recommended Actions
0.1 GPH Compliance
Expired
Line A 0.1 gph test has not been
completed within the last 365
days.
Verify that no pertinent alarm conditions have been reoccurring.
Ensure that there is enough time to pass the test.
0.2 GPH Compliance
Expired
Line A 0.2 gph test has not been
completed within the last 30 days.
Verify that no pertinent alarm conditions have been reoccurring.
Ensure proper seating pressure. If Firmware revision is older
than 1.7.4.5535, upgrade to make use of the Statistical Line Leak
Detection enhancement.
3 GPH Compliance
Expired
Line The required daily 3 GPH test has
not been completed.
Check for continuous pump on conditions that could be caused by a
sticky handle switch or relay.
Air in Line Line Air has been detected in the line. Purge all air from the line starting at the furthest dispenser and
working in toward the STP. Verify tightness of lines and investigate
other sources for air infiltration.
Dispensing Pressure Test
Failed
Line Pressure during dispensing
dropped below 7.5 psi. This is
seen as a catastrophic leak during
dispensing.
Inspect all sumps for product. Use a pressure gauge to test line
pressure during dispensing. See “LS500 Auto Learn Line Leak
Detection Installation & User’s Guide” FFS 000-2145. Contact
Franklin Fueling Systems’ Technical Services Dept. for support.
Extended Hook Signal Line A hook signal has been detected
for more than 60 minutes with the
line pressure staying the same.
Check for voltage to the AC-Input module. If issue still exists contact
Franklin Fueling Systems’ Technical Services Dept. for support.
Failed to Catch Pressure Line The pump OFF pressure has
dropped below 7 psi within
1 second after the pump was
turned off
Inspect all sumps for product. Refer to “LS500 Auto Learn Line
Leak Detection Installation & User’s Guide” FFS 000-2145 for more
information.
Failed to Pressure Up Line The Line has called for the pump
to turn on but did not see the
pressure increase
Inspect all sumps for product. Refer to “LS500 Auto Learn Line
Leak Detection Installation & User’s Guide” FFS 000-2145 for more
information.
Gross Leak Detected Line The console has detected a line
leak greater than 3 gph.
Inspect all sumps for product. Refer to “LS500 Auto Learn Line
Leak Detection Installation & User’s Guide” FFS 000-2145 for more
information.
High Pump Pressure Line The Pump Off pressure has
stayed above 49 psi for 3
consecutive times.
Inspect all sumps for product. Ensure that no other check valves are
used within the system. Observe multi-point line pressure readings
during pump on and off using a pressure gauge in the line. If line
pressure is high, there may be a blockage in the line. Refer to “LS500
Auto Learn Line Leak Detection Installation & User’s Guide”
FFS 000-2145 for more information.
Line is not configured Line Specified line is not configured,
therefore line leak test will not be
performed.
Verify line programming. If necessary configure line.
