Overview of LL2 Probe
The INCON LL2 probes are advanced instruments that
use magnetostrictive position measurement technology to
accurately report inventory levels in storage tanks
The probes are installed in USTs (underground Storage
Tanks) and ASTs (above ground storage tanks). Leak
Detection probes are suspended by a chain from a cap on
the riser pipe. Inventory probes may be suspended by a chain
and cap or alternatively be mounted on the bottom of the
tank. Bottom mount hardware is provided on all inventory
probes.
Types of Probes
• Leak Detection
• Inventory Specic
Length of Probes
The probe model number indicates its length. The model
numbers are in the form TSP-LL2-xxx, where xxx = the
tank diameter in inches plus 5.
For example, the TSP-LL2-101 is for 8’ (96”) tanks.
TSP-LL2-xxx, Leak Detection and Inventory probes are
available in lengths up to 12' tanks.
TSP-LL2-xxx-I, Inventory Specic probes are available in
lengths up to 18' tanks.
Warning
Warning
Warning
Warning
Always secure the work area from
moving vehicles. The equipment
in this manual is usually mounted
underground, so reduced visibility
puts service personnel working on
this equipment in danger from moving
vehicles entering the work area. To
help eliminate these unsafe conditions,
secure the area by using a service
truck to block access to the work
environment, or by using any other
reasonable means available to ensure
the safety of service personnel.
When the console system is used to
monitor tanks containing gasoline or
other ammable substances, you may
create an explosion hazard if you do
not follow the requirements in this
manual carefully.
All wiring must enter the console’s
enclosure through the designated
knockouts. An explosion hazard may
result if other openings are used.
All wiring from probes to the console
must be run in conduit separate from
all other wiring. Failure to do so will
create an explosion hazard.

1. Push the probe’s cable though the compression
gland tting at the waterproof junction box. Make
sure that you leave enough cable from the level
probe to the junction box (tie-wrap a coiled service
loop) so that the probe can be easily removed and
reinstalled without rewiring and splicing.
2. Tighten the compression gland tting at the
junction box so that it grips the cable tightly and
creates a watertight seal.
3. Position the lockable TSP-K4A probe cap on the
riser cap adapter such that the compression tting is
aligned with the rubber grommet and snap it in place.
4. Tighten the riser cap compression tting so that it
grips the cable tightly and forms a watertight seal
When using a 2" riser you will remove the top spacer and
replace the bottom spacer with the 2" spacer included in
the oat kit. When using a 3" riser, cut back the top spacer
and replace the bottom spacer with one included in the
oat kit. The 4" probes are installed with no modication.
This is solely for the I-probes, all leak detection and density
probes MUST BE Suspended.
Single Thermistor Probe
The probe will have one RTD near the bottom of the
probe shaft. The Net Volume will be based on the one
temperature reading vs. the average of the 5 RTDs in
current Inventory probes.
Note: The Inventory Probes MUST NOT be used for Leak
Detection.
A sticker on the head of the I-probe indicates that it is for
inventory use only. An extra sticker is provided to be kept
near the console for gradient programming. Installers must
be aware of the probe type in sites that have a mix of
inventory-specic and leak detection probes.
Note: When removing the probe, loosen the cable
compression tting.

Tank Tilt / Offset Calculations
If the data to calculate tank tilt is not known, or if the tank is
not seriously tilted, then use +/– offsets to adjust the probe
readings to match the stick readings at ll.
Figure 10 shows the tank tilt formula to use when the ll
tube and probe are on opposite sides of the tank centerline. Figure 11 shows the formula to use when the ll tube
and probe are on the same side of the tank center-line.

Troubleshooting
When troubleshooting a probe problem, it is important not
to presume any particular cause. Follow the steps outlined
below to properly and quickly troubleshoot probes:
Note: Do not start troubleshooting by swapping probes. It
may cause confusion in the process of identifying
the problem.
Float Missing:
1. Check programming of probe for correct number
of oats
2. Look for active High water or Float Missing Alarms
in the run status at the ATG.
3. If possible, have the technician stick the tank and
compare the measurement with the level reported
by the ATG.
4. Is the level correct? If not, is the ATG measuring
in reverse (the lower the actual product level the
higher it reads on the ATG)? Verify the Probe ratio
is programmed correctly. If programming is correct it
may be a probe issue, continue with the next steps.
5. Check the water level does the ATG list it as oat
missing? If it is listed as missing, it could be a
probe issue, but again continue to troubleshoot.
6. Try to cycle power. If previously noted, check to
see if High water alarm or oat missing alarm
changed from “ACTIVE” to “CLEARED”. If they
clear, again this could be a probe issue, but
acknowledge and continue to troubleshoot.
7. After completing the above steps, replace the
probe.
No Probe, Probe Sync and Unstable Probe
(New Install or Replacement Probe)
1. Check Wiring. Ensure that the Red, Black and
Shield wires are connected to the correct terminals
to the ATG. There should be two connections in
the junction box, (refer to gure 8).
(Probe Alarms on Multiple Channels or Only One Probe
Connected)
6. Try another Probe Channel. Once the eld wiring
has been checked and the junction box connection
remade, try moving the eld wiring to another
channel.
7. Connect the Probe Directly to the ATG. If possible,
bring the probe inside and wire directly to the ATG.
(If this probe has a quick disconnect pigtail then
the white wire should be connected to shield or
ground).
Listed below are additional steps for troubleshooting
the probe. For missing oat or incorrect level problems,
consider the following actions:
•
Pull probe from tank and manually raise and lower oats.
Does the ATG accurately report the change in level?
• Are the right number of oats installed on the probe
(verify number of oats programming)
• Is oat too close to the end of the probe? (Was tank
overlled or is the oat stuck in riser)? If oat is too close
to the probe head a oat missing alarm will occur.
• Is there debris on the magnets? If so, clean debris from
magnet and check operation of ATG.
• Are the magnets cracked or broken? If so replace oat
• Are the oats installed correctly? Product oat on top,
closest to the probe head. Product oat will have a white
collar. Water oats have colored collars (Red for use in
gasoline, blue for use in diesel)
• Is the probe shaft clean? If dirty use an abrasive pad to
clean the probe shaft.
• Check that wire connections from probe cable to eld
wiring are good and dry.
• Are the oats compatible with the probe? LL and LL2
oats are NOT interchangeable.
2. Check Main Board Power Supply. There should be
approximately 21 VDC loaded (probe connected)
and 24 VDC unloaded across the Red and Black
terminals of the probe channel in the ATG.
3. Check Field Wiring. Ensure that the voltage is
getting to the probe by checking at the junction box
splice or quick disconnect pigtail. With the pigtail
end facing you, keyslot up, there should be 24
VDC across the two bottom pins. Test eld wiring
for a short or open.
4. Remake Splice. Cutback and remake the splice
connection in the junction box using the approved
seal pack and connectors.
(Quick Disconnect Pigtail)
5. Try a New Pigtail. If this probe has a quick
disconnect pigtail, try replacing it.
