Wire Sensor Alarms
SN2 Sensor On ChannelSN2 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 sensor.
Contact Franklin Fueling Systems’ Technical Services for support.
SN2 Fuse Blown ChannelSN2 2-Wire Sensor Module fuse blown
due to unknown causes.
The fuses on the Sensor boards are non-serviceable per UL listing
standards. The module must be replaced if the fuse is blown.
SN3 Data Error ChannelSN3 Console has received erroneous
data from sensor.
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 sensor. If the condition still exists,
contact Franklin Fueling Systems’ Technical Services for support.
SN3 Dry Well ChannelSN3 Monitoring well is dry. Visually verify that the alarm is correct.
SN3 Fuse Blown ChannelSN3 3-Wire Sensor Module fuse blown
due to unknown causes.
The fuses on the Sensor boards are non-serviceable per UL listing
standards. The module must be replaced if the fuse is blown.
SN3 High Brine ChannelSN3 Brine solution has tripped high
level brine sensor.
Verify actual level of solution and sensor installed location.
SN3 Low Brine ChannelSN3 Brine solution has tripped low level
brine sensor.
Verify brine level and sensor location.
SN3 ID Error ChannelSN3 Discriminating sensor is given an
improper ID.
Verify sensor programming and Auto configuration.
SN3 No Signal ChannelSN3 Console is not receiving data from
a discriminating sensor.
Verify programming of sensor type and wiring connection.
SN3 Product ChannelSN3 Discriminating sensor has
detected product present at
location.
Visually inspect location carefully 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.
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.
