2.4 Console Wiring
For console power wiring, please refer to the appropriate field wiring
diagram. See Sections 2.7 and 2.8 for the type of console being
installed.
The console must share the same phase with all other OPW ATG
components. Use knockouts “A” in Diagram 2-2 to route three (3) (14
AWG minimum) stranded copper wires for Line, Neutral and Ground.
A fourth wire (12 AWG minimum) is needed if the console is equipped
with an internal I.S. barrier, which is always needed with Integra 100
consoles.
2.4.1 Petro-Net™ Wiring (only for Integra 500)
Wired RS-485 Petro-Net™ connections can be used for
communications among the VSmart module, OM4 and the console.
For this type of connection, a single run of twisted-pair wiring (10
twists per foot) is required. Polarity must always be observed for
Petro-Net connections.
NOTE: Twisted-pair wiring is available from OPW as Part No. 121029.
When connecting via Petro-Net, the twisted-pair wiring is connected
to positions 7 and 8 of the RS-485 terminal block (J21) at each
module. Petro-Net™ connections can be wired parallel, meaning that
modules may be connected to each other in various combinations as
long as one module in the chain is connected to the console.
NOTE: Petro-Net™ connections must be made with twisted-pair
wiring. The use of conduit is recommended for protecting PetroNet™ wires, and may be required per NEC depending upon
application. If conduit is not used, bushings must be installed in the
cabinet knockouts to protect wiring and seal the enclosures.
2.4.2 Wireless Connections (only for Integra 500)
Wireless connections can also be used for communications between
the VSmart module and the console. For this type of connection, a
wireless modem is connected to the VSmart module, and a second
modem is wired to the console’s RS-485 port. The VSmart modems
must be within a clear line-of-sight. See figure in Section 2.5. Also,
please refer to the M00-20-7074 Wireless Petro-Net Manual.
NOTE: Wireless connections are not viable options at all installation
sites due to the presence of interference or line-of-site obstacles.
Test kits are available, but A SITE SURVEY IS STRONGLY
RECOMMENDED BEFORE COMMITTING TO WIRELESS
INSTALLATIONS.
2.4.3 Ethernet Connections to VSmart (only for
Integra 500)
When equipped with the optional VSmart LAN capability, Ethernet
connections are the only option for establishing communications
between the console and VSmart. For this type of connection, an
Ethernet cable is run between devices at a maximum length of 300
feet (92 m). This distance can be extended through the use of hubs
and routers.
NOTE: If more than 6 feet (1.85 m) of cable is required, the use of
conduit to protect the cable is recommended.
NOTE: The VSmart module must be ordered with this option.
An Ethernet connection can also be established between the console
and a VSmart Module using an existing network. To make this
connection, simply connect the console to one node on the network
and the VSmart Module to another node. See figure in Section 2.6.
NOTE: You will likely require the site’s IT personnel with this type of
installation.

Doc. #: M1800, Rev. 06
Page 13 of 99
2.4.4 RS-232 Communications Conduits
If a terminal or PC located more than 6 feet (1.8 m) from the console
is to be connected, conduit must be installed to accommodate the RS232 cable.
NOTE: The maximum runs for serial communication cable is 50 feet
(15.24 m).

2.5 Wireless Petro-Net Installation with VSmart Indoors
NOTE1: Directional antenna may be substituted for
omni-directional antenna depending upon site
conditions.
NOTE2: It is highly recommended that all wireless
Petro-Net installations are subjected to a site survey
prior to installation to identify potential interference
problems.
NOTE3: VSmart Module is NEMA 4-rated, and may,
therefore, be mounted outdoors.

5 Line Interface Module LIM (only for
Integra 500)
The LIM is an external device that controls and monitors submersible
turbine pump (STP) activities by monitoring the input/output status of
the dispenser hook signals and STP relays.
Each Line Interface Module (LIM) (maximum of four (4) per system)
will monitor up to four (4) STP motors per module (for a total of 16
STPs per system). In the case of manifold submersible pumps, only
one (1) LLD sensor is installed, but the manifold will require one LIM
position for each submersible pump.
5.2 LIM Installation
The LIM must be mounted on a wall using only the mounting holes
provided. Knockout locations are shown below. LIMs require
communication connection to the console and AC power.
NOTE: The LIM module is not NEMA-rated and must not be mounted
with direct exposure to the elements.
NOTE: Only use the knockouts provided. Seal all unused knockouts.
Typically, the dispenser sends a “hook signal” (110 VAC) to the
submersible pump controller. A LIM functions by intercepting this
hook signal and communicates via Petro-Net with the console. The
LIM sends a 110/220 signal to the STP controller to turn the
submersible pump ON, unless an alarm condition is detected, then
no signal is sent. An HV feedback signal confirms that the
submersible pump is turned ON.
The LIM works in conjunction with the console to test the lines during
periods of inactivity to constantly monitor the site for leaks in the
line(s).

the following QR Code. Or, the instructional video can also be found
at www.YouTube.com by entering the search word “OPWGlobal”.
LIM modules should have dedicated AC power and two (2) ground
connections for the module and barrier.
With every LIM installation, noise suppressors are required to reduce
the “noise” when the STP coil contact closes; thereby, clipping the
noise back through the HV Feedback and HV Output.
1.
2.
Pull two (2) AC power wires and one (1) ground wire (14AWG minimum) from the circuit breaker to each LIM module.
All AC power must be in the same phase.
Figure 5-2 LIM Module Wiring Connections
Note the phase the LIM relay is on connected to the STP terminal
motor. The LIM should be on the STP HV Feedback phase, as shown
in Figure 5-6. This may vary slightly depending on the type of STP
on site.
3.
Install the noise suppressor between the coil of the LIM relay
and neutral, and the phase leg of the STP and neutral in the
STP contact.

To watch the instructional video for the use of the Epoxy packs, simply
use the following QR Code. Or, the instructional video can also be
found at www.YouTube.com by entering the search word
“OPWGlobal”.
1.
Twist bare ends of wires together.
2.
Secure the connection with a wire nut.
CAUTION: DO NOT use electrical tape on any connections! Tape
prevents proper sealing of the epoxy.
3.
Waterproof
the
connections
with
the
supplied
SCOTCHCAST™ epoxy resin Insulating Resin Seal packs.
They are provided to seal the electrical connections from
moisture and water and prevent corrosion of the
connections. Install one for each cable connection.
4.
Bend the seal pack until the barrier between the two resins
weakens.
5.
Force the clear and the black resins together and mix
thoroughly.
6.
Move the mixture to one end of pack, then clip the other end.
7.
Insert wires, wire nuts and the cable insulation end into the
seal pack.
8.
Work the resin mixture into the ends of the wire nuts and
around both cable jackets.

Secure the seal pack around the cables with a tie
wrap and cable tie.
Figure 8-1 Waterproof Electrical Connections
It is VERY important to seal all probe and sensor connections in the
junction box to prevent corrosion of the wires.

Page 36 of 99
8.2 Probe-Cable Seal-Offs
Seal-off the probe cables before they enter the I.S. barrier! This
prevents explosive vapors from entering the I.S. barrier.
1.
2.
3.
4.
Remove enough of the jacket to allow approximately 3
inches (7.6 cm) of wire leads to extend past each seal-off.
DO NOT nick the wire insulation.
Probe or sensor wires using prepared Belden or Alpha cable
go through NPT bushings into a weatherproof junction box.
Bushings must be used in all junction boxes.
The cable is then routed—via rigid steel conduit—out of the
box and directly to the I.S. barrier.
Label each cable and wire.
CAUTION: Only OPW probe cables and sensor wiring can share the
conduit to the I.S. barriers.
CAUTION: Improper cables, wiring, or conduit allow electronic noise
to interfere with probe/sensor measurements. This may cause
measurement readings at the console resembling hardware failure.
The warranty is voided if improper cables, wiring and/or conduit are
installed. The ground wire must be properly installed for the operation
of the noise-filtering circuitry. Do not rely on the conduit for the
operation of the ground.
CAUTION: The console must have a dedicated power circuit, and
must be on the phase as all other OPW equipment.

Page 37 of 99
8.3 Probe Placement
The ideal location for a probe is in the center of the tank. The probe
should be located at least 3 feet (91.4 cm) from the tank fill pipe. If
this distance is less than 3 feet (91.4 cm), the force of the product
entering the tank can cause the water float to rise up the shaft of the
probe. This may cause the Integra to generate a false high-water
alarm. Adjust the drop tube of the fill pipe so that the product flow is
diverted away from the probe.
CAUTION: Integra probes are safe for Class 1, Div 1, Group D
hazardous locations. This includes tanks containing regular, super,
diesel and unleaded gasoline; antifreeze; kerosene; mineral spirits;
oxinol, methanol and methanol blends; motor, torque and
transmission oil; and alcohol. If you have any questions about
whether a product is included in this classification, please contact
your product distributor or OPW FMS distributor. Integra probes
(Model 924A & 924B, EECO, or AST 7100 Flex) must be installed as
described in this section. If the minimum or maximum dimensions
specified cannot be met, do not proceed with the installation.

8.4 Probe Installation in Underground
Storage Tanks
1. Install a manhole of at least 18 inches (45.7 cm) diameter
around an unused fitting in the top of the tank. This
manhole must be large enough to accommodate a
weatherproof junction box.
NOTE: If this fitting is not in the center of the tank, additional
measurements are required for probe compensation.
2. When installing the probe, allow enough cable from the
probe to reach a weatherproof junction box.
3. Leave minimum 12 inches of extra, coiled wiring (probe
wire and field wire) inside the weatherproof junction box.
The box must be large enough to accommodate ½-inch
(12.7 mm) conduit, coiled field wiring and epoxy pack, as
shown in field wiring diagram.
CAUTION: Seal-offs are required at any time I.S. wiring enters
conduit.
4. Install the ½-inch NPT bushing (supplied with each probe)
in the weatherproof junction box.

8.4.1 Calculating Product Offset
You can calculate product offset for a probe that is not installed in the
center of a "pitched" tank. Pitch is the tilt of a tank along its horizontal
axis. Some tanks are intentionally installed with one end lower than
the other to allow water and sediment to collect at the low end, while
clear product is drawn from the high end. Tank settling can also cause
pitch. The rate of pitch can be measured by using a dipstick to
measure the level of product at two points (preferably opposite ends)
of the tank (see Figure on right).
The product depth at the deep (lower) end of the tank is value “A.”
The product depth at the shallow (higher) end is value “B.” The
distance between the two measuring points is “C.”
The formula for pitch is:
Figure 8-5 Calculating Probe Offset
(A-B)/C
For example:
(46"-40")/120" = 6"/120" = 0.05”
To calculate the product offset, measure value “D,” the distance of the
probe from the center of the tank. The formula for product offset is “D”
x pitch. For the above example, 36” x 0.05 = 1.8”.
If the probe is located closer to the shallow end of the tank, the
product offset is positive; for the example, 1.8”.
If the probe is located closer to the deep end of the tank, the product
offset is negative; for the example, -1.8”.

9 Rigid Probe Installation
NOTE: TLMB probes do not work with an Integra 100™ or 500™
console; even if you are upgrading from an EECO console to an
Integra™ console, a TLMB probe it will not work.
9.1 Adaptor Collar & Riser Cap
Sensors and probes cannot be multi-dropped from the same I.S.
Channel; therefore, you must run sensors and probes to different
channels on the barrier.
Seal packs are required with all wiring applications in the field.
Weatherproof junction boxes are REQUIRED with ALL I.S. field
connections.
A modified adaptor collar and riser cap (OPW Model 62M) is required
for each probe. These collar and riser cap kits are available from
OPW Fuel Management System.
1. Install the modified adaptor collar onto the riser pipe.
2. Next, screw in the OPW-supplied bushing (62 mm) with
the probe into the 3/8-inch NPT hole in the riser cap.
3. After the probe is lowered into the tank, snap the cap into
place.
9.2 Probe Floats
There are three types of floats used with the probes: Product, Water
for Diesel, and Water for Gasoline.
Note that the two types of water floats are NOT interchangeable.
Because diesel is denser than gasoline, the water/diesel floats are
heavier than the water/gasoline floats. If the wrong water float is
installed in a diesel tank, it does not sink through the product to the
water below. As a result, the tank will have unusually high water
measurements and possibly erratic product measurements as the
water float interferes with the product float.
Figure 9-1 Multi-drop Probes on I.S. Barrier
NOTE: Water float assembly for flexible AST probes is only available
for use in 4-inch (10.2 cm) riser installations.
9.3 Multi-drop Installation
The Integra’s internal barrier and optional VSmart Module allows for
the ability to multi-drop the sensors and probes. When using this
installation method, follow the below directions to ensure approved
wiring.

10 Flex Probe Installation
10.2 Model 7100V Flex Probe Specifications
10.1 Model 7100V Flex Probe (only for Integra
500)
The 7100V Flex Probe utilizes the same magnetostrictive technology
for above ground tanks up to 70 feet (15.2 m) in height. It is important
to follow the handling instructions to avoid damaging the probe and
voiding the warranty. During the unpacking and installation of the
Model 7100V Flex Probe, always keep the diameter of the coils
between 40 and 48 inches (about 1 m).
Flex Probe Installation Requirement: Flex probe head/wiring must
be installed in weatherproof junction box with seal packs for wiring
connections. Failure to comply with these requirements may
invalidate probe warranty.
DO NOT
REMOVE

Doc. #: M1800, Rev. 06
Page 45 of 99
10.3 Flex Probe Installation
Proper operation of the ATG system using the flex probe depends on
the correct sizing of the probe. If the probe is too long, it will touch the
bottom of the tank and bow, causing either inaccurate or lost
readings. If it is too short, product measurement range will be
compromised.
NOTE: Each Flex Probe is custom made to fit a particular tank. They
are not returnable if an error is made in determining the correct
length.
10.3.1 Flex Probe Length Determination
1. The flex probe mounts to the tank with a ¾-inch NPT
male thread. Obtain the proper fittings to adapt the
tank opening to a ¾-inch NPT female thread. Do not
use the tank’s vent opening to install the flex probe.
2. Temporarily install this hardware in the tank opening.
3. Using a plumb bob or measuring tape measure the
distance (in inches) from the top of the ¾-inch NPT
flange to the bottom of the tank. Save this
measurement, which will be Total Height (TH).
4. Flex probes are ordered by overall length (OAL).
Overall length is the distance from the top of the ¾inch NPT wiring bushing to the tip of the probe. OAL
(inches) = 1.5 + (TH x .993)


10.3.2 Flex Probe Installation Preparations
1. Measure the product level in the tank. Keep tank out
of service to prevent product level from changing.
2. Make note of the probe information found on the
probe serial number tag.
3. Locate standard plumbing fittings that will adapt your
tank opening to the ¾-inch NPT required for the
probe.
4. Wipe any excess sealant from the inside of the fittings
to prevent any from getting on the probe shaft during
installation.
CAUTION: Do not remove yellow tag; refer to image in Section 10.1.
If cable runs to 750 feet (229 m) use Belden #88761
If cable runs to 1,000 feet (305 m) use Belden
#8760, #88760 or #8761
NOTE: Some electrical codes require intrinsically safe wiring to have
a blue jacket.

10.3.5 Installing the Flex Probe
10.3.4 Flex Probe Wiring
1. Run one data cable for each probe. No splices are
allowed between probe junction box and console.
Multiple flex-probe cables are allowed in one conduit.
Use labels to mark TANK # on each cable at the
console.
2. Leave 16-inches (40.6 cm) in length of extra cable
inside the probe junction box.
3. Install fiber dam and sealing compound in all vapor
seal-off fittings. Installing Adaptor, Float, Weight on
the Probe.
4. Carry the probe to the top of the tank in its rolled-up
state. Do not remove the tie wraps.
5. Carry the floats and remaining installation
components to the top of the tank.
6. Cut only the tie wrap (Labeled #1) that is securing the
tip of the probe to the rest of the coil. This should
provide enough length to install the float and related
hardware (see Section 9.5.2).
7. Assemble the remaining adaptor hardware that the
float will not fit through and slide this adaptor
assembly onto probe. Do not apply thread sealant at
this time.
8. Install the product float on the probe shaft with the
magnet towards the bottom of the probe.
9. Install the weight on the probe shaft with the recess
toward the bottom of the probe.
10. Install the weight-retaining pin through the hole in the
tip of the probe.
1. Position the coiled probe over your shoulder so that
the coil is vertical with the float in front of you.
2. While holding the adapter hardware, carefully feed
the weight and floats into the tank opening. Be careful
not to scratch the probe shaft during the installation.
3. Cut the next tie wrap (Labeled #2) and continue
feeding the probe into the tank.
4. While slowly uncoiling probe, continue cutting the tie
wraps in order until the probe is fully installed in the
tank.
5. Hand-tighten the probe head into the still loose
threaded adaptor hardware. Thread sealant is not
required on the nylon probe bushing.
6. Install the rest of the adaptor to the tank using a
minimal amount of thread sealant.
NOTE: Nylon probe bushing is easily cross-threaded.
10.3.6 Finishing the Flex Probe Installation
1. Connect the probe wiring bushing ½-inch NPT to the
junction box using a short length [18 inches (45.7 cm)
max] of flex conduit.
2. Connect the probe to the cable in the junction box and
console (as shown in image from Section 9.4).
3. Verify that the probe is operating correctly at the
console.
4. Waterproof the probe connections at the junction box
with the epoxy seal-pack and close the junction box.

12.3 Multi-drop Installation
The Integra’s internal barrier and optional VSmart Module allows for
the ability to multi-drop the sensors and probes. When using this
installation method; follow the below directions to ensure approved
wiring.
NOTE: Sensors and probes cannot be multi-dropped from the same
I.S. Channel; therefore, you must run sensors and probes to different
channels on the barrier.
NOTE: Seal packs are required with all wiring applications in the
field. Weatherproof junction boxes are REQUIRED with ALL I.S. field
connections.
12.2 IntelliSense™ Technology
This technology allows the Integra and I.S. barrier to automatically
detect sensor connection, sensor type and sensor status. IntelliSense
will minimize user entry error and identify hardware issues with
minimal troubleshooting.

12.4 Interstitial Sensor
Interstitial Sensors can be installed around the inside perimeter of the
retaining wall or “snaked” under the length of an above ground
storage tank within the retaining wall area.
Interstitial Sensors can also be installed in manways, in trenches or
inside a sump.
12.4.1
Interstitial Sensor Installation
1. Place the Interstitial Sensor in its intended location.
When installing the sensor in a sump, place the
sensor at the bottom of the sump.
2. Connect the sensor to the I.S. Barrier by splicing the
sensor wires to field wires. These wires, in turn, pass
through vapor seal-offs and enter the VSmart Module.
3. Keep track of sensor-wiring identity to ensure proper
wiring at the VSmart Module. A below-grade wiring
workbox can be used as a junction box for the splice
when wiring underground. Follow all applicable
codes.
4. Run separate wiring from each sensor to the chain
leading to the VSmart Module if using the multi-drop
connection method; otherwise, run separate wire for
each sensor.

Hydrocarbon Liquid Sensor Installation
The Hydrocarbon Liquid/Water, which is available in lengths of 6 feet
(1.8 m), 15 feet (4.6 m) and 20 feet (6.1 m), is used primarily for
monitoring wet wells with fluctuating groundwater tables. The sensor
contains a carbon/polymer material that changes its resistance when
exposed to liquid hydrocarbons. Additionally, a water sensor that
relies on the conductivity of water to detect its presence is utilized,
providing the ability to discriminate between hydrocarbon liquid and
water. An alarm condition will result from the absence of groundwater
in a monitoring well. Detection of fuel entering the containment area
(indicating a leak) will also result in an alarm condition, as will a break
in the cable or sensor malfunction.

Universal Reservoir Sensor
Use a Universal Reservoir Sensor with hydrostatically monitored
tanks. The Reservoir Sensor monitors the level of the liquid in the
reservoir of a double-walled tank. The sensor has a single float that
detects abnormally high or low liquid levels within the reservoir. If a
leak occurs in either wall of a tank, it causes the liquid in the reservoir
to rise or fall. When liquid reaches the upper or lower limit on the
sensor, the sensor activates.

Density Measurement Sensor
The Density Measurement Sensor (DMS) installs on the pre-existing
probe and continuously measures the average density of the fuel in
the tank. This provides a measure of even the smallest change in
product density within the API density range. Fuel-density reports can
be displayed real-time on the console or exported to an external
device. The readings can be either nominal or temperature-corrected
density.
www.opwglobal.com
Doc. #: M1800, Rev. 06
Page 70 of 99
DMS Installation
NOTE: As density sensing is no longer an option in the system, the
sensor itself will be picked up by the system once the device is
installed and after redoing Auto-Detection of the probe.
1. Take the probe out of the tank and remove the clip
and nylon probe foot at the bottom of the probe.
2. Remove the water float, slide the density sensor on
and tighten the screws of the sensor onto the probe
shaft (the umbrella should be facing down). Leave a
space of at least 4 to 6 inches (10.2 cm - 15.2 cm) at
the bottom of the probe shaft to allow the water float
to detect at least 3 inches (7.6 cm) of water.
3. Replace the water float, nylon probe foot and end clip.
4. Place probe back in the tank.
Tank Thresholds
1. As the Density Sensor is installed between the water
and Product Float, the Product Float will not be able
to go further down than the Density Sensor. In order
to provide low-product alarms, the Low and Low-Low
product threshold level should be set above the
Density Sensor. The suggested level is 17 inches
(43.2 cm) or higher.
2. Measure the distance between the end of the probe
shaft and top end of the Density Sensor. To this
distance, add 2 inches (5.1 cm) to account for the
dead zone at the end of the probe. The resulting value
represents the minimum product Low-Low threshold.

The Model 924A Probe utilizes magnetostrictive
technology to derive accurate product and water levels. It
is primarily used in underground storage tanks for
inventory and leak detection. Two floats can be fitted to
the probe shaft; the product float sits on top of the product
and the water float (optional) sinks through the product
and sits on top of the water at the bottom of the tank.
Five temperature sensors reside in the probe shaft for
measuring product temperature at different levels in the
tank. They are located at positions of approximately 20%,
40%, 60% and 80% of the tank’s volume. The sensors
feed the data of the temperature of the fuel to the console.
The console software is then able to make the
calculations to produce a net corrected product volume.

Hydrocarbon Liquid/Water Sensor
OPW P/N: 30-3210-nn
Hydrocarbon Liquid/Water Sensor
The hydrocarbon liquid/water sensor is used primarily in monitoring
wells with fluctuating groundwater tables, or in the containment areas
of tanks, pumps and pipes.
The sensor contains a carbon/polymer material that changes its
resistance when exposed to liquid hydrocarbons, as well as a water
sensor that relies on the conductivity of water to detect its presence,
providing the ability to discriminate between hydrocarbon liquid and
water.
The sensor also alerts the system to the absence of groundwater in
a monitoring well, or the presence of water in containment areas. It
will alert the system if any fuel enters into the containment area, which
would indicate a leak. In the event of a break in the cable, the system
will activate the alarm.

vapors in dry monitoring wells. The presence of these vapors could
indicate a potentially dangerous leak that could lead to safety and
environmental problems.
The sensor is made from a long-life resistive element that increases
dramatically in resistance in the presence of hydrocarbon vapors.
After the vapors have dissipated, the sensor returns to normal and is
ready to detect hydrocarbon vapors again. This process could take
up to 30 minutes depending on the saturation factor. In the event of a
break in the cable or any sensor malfunctions, the system will activate
the alarm.

Combo Single-Level/Hydrocarbon Liquid Sump Sensor
This sensor is made from the Hydrocarbon Liquid Sump Sensor (303219-12) with an Interstitial Level Sensor (30-3221-1A) clipped to its
side. The combination sensor is designed to detect the presence of
liquid hydrocarbons and water in sumps, dispenser pans and other
locations where the presence of a liquid could indicate that a leak has
occurred.
The sensor contains a carbon/polymer material that changes
resistance when exposed to liquid hydrocarbons. The level sensor
portion simply clips onto the hydrocarbon sensor and can be
positioned at any desired height to activate in the presence of liquid.
This sensor can be used to monitor wet wells to ensure that a liquid
is normally present. In the event of a break in the cable, the system
will activate the alarm.
