1 Introduction
This manual describes the installation procedures for the SiteSentinel® iTouch™ Integrated Monitoring System.
Included in this manual are installation instructions for the Controller, probes and sensors.
1.1 Warnings
1.1.1 Safety
When working in an environment containing fuel and fuel vapors, there is ALWAYS a
risk of fire and explosion.
TO AVOID SEVERE INJURY OR DEATH, KEEP ALL POSSIBLE IGNITION
SOURCES AWAY FROM HAZARDOUS AREAS.
1.1.2 Fire and Explosion Hazard
Disconnect power before installing. DO NOT install this equipment in a volatile,
combustible or explosive atmosphere (the “hazardous area” defined in the National
Electrical Code).
1.1.3 Dangerous Voltages
Certain components have DANGEROUS voltages even with the power cord
disconnected.
Many of the procedures described in the following pages must be followed for each
tank that is to be included in the system. Please read the directions carefully before
proceeding.
Improper installation may endanger installers and users of this equipment!
Read these instructions CAREFULLY.
Installers must know the requirements of intrinsically safe devices, and must
strictly obey instructions in this manual to perform a safe installation.
1.1.4 Compliance
Installation must comply with the National Electrical Code (NFPA No. 70) and the Autom
Service Station Code (NFPA No. 30A).
Follow all of your local or regional codes, as well.
A fuel tank is a hazardous area as defined in the NEC. Do not mount any part of the system, or any
external devices (other than probes or sensors) within or above the hazardous area.
1.1.5 Precision Leak Test
A precision leak test should be performed on each tank - especially older ones - before installing the
SiteSentinel® iTouch™. This test makes sure that leak data generated by the system is accurate and reliable. A
pressurized precision leak test can be done on a tank after the probe has been installed, but DO NOT let the
pressure exceed 20 psi.
Page 10 of 123
4.4 Wiring the Controller Power Supply
The power supply automatically adjusts for supply voltages from 100 to 250 VAC
1. Pull two #14 AC power wires and one #12 AWG ground wire through the conduit from the distribution
panel to the local breaker dedicated to the controller.
2. Pull two #14 AC power wires and one #12 AWG ground wire through the conduit from the local
breaker to the controller.
3. Pull just enough wire through the bushing to attach to the 3-pin green terminal block located on the
right of the controller circuit board.
Connect AC neutral and AC hot wires (order not important) to pins 1 and 3 of the green terminal block.
Center pin is not used. Attach the cover to the terminal block.
4. Attach the ground wire to one of the ground terminal studs (near the top knockouts marked as ground)
and run back to the main distribution panel for connection.
The ground wire must be #12 AWG or larger.
Some countries/states require a redundant ground wire; this should be attached to the second ground
terminal stud and run back to the main distribution panel for connection.
Power wiring must enter the controller via the designated power conduit knockout.
Connect the power wires to a dedicated circuit.
See Specifications on page 12 for power requirements.
Protecting communication ports and ensuring site intrinsic safety for the SiteSentinel® iTouch™
Proper Grounding of the SiteSentinel® iTouch™ is essential for protecting the communication ports and
lessens the risks of hazardous situations occurring when power surges or lightning strikes happen. This
document outlines the recommended practices for a safe and damage-free installation.
Page 20 of 123
4.4.1 Grounding the SiteSentinel® iTouch™ Tank Gauging System
There are two ground lugs within the SiteSentinel®
iTouch™ (See Figure 4-4 below) You will need to
install two continuous ground wires (green 12 AWG or
larger) from both ground lugs connected back to the
distribution panel ground. The intrinsic barriers rely on
these ground connections; if they are not present the
barriers will not work. The redundant ground ensures
that the SiteSentinel® iTouch™ will operate properly
and safety.
4.4.2 SiteSentinel® iTouch™ Port
Protection
The communication ports can be damaged by ground
faults within the SiteSentinel® iTouch™. If you are
communicating from another type of system, such as a
Figure 4-4 SiteSentinel® iTouch™ Ground Lugs
point-of-sale (POS) system, to the SiteSentinel®
iTouch™ and there is a slightly ground potential
difference, this difference will either cause
immediate failure of the SiteSentinel® iTouch™, or
will cause a failure over time. To eliminate this
possible damage, make sure the other equipment
is grounded back to the same ground potential as
the SiteSentinel® iTouch™ at the distribution panel.
In addition, a 12 AWG or larger wire can be run
from the ground lug in the SiteSentinel® iTouch™
to the ground of the other equipment.
OPW Fuel Management Systems can supply an
external surge suppressor (Part # 75-0104), see
Figure 4-5 to the right. This device will help protect
the ports from power surges or lightning strikes.

5 Preparing for Probe and Sensor Installation
5.1 Probe and Sensor Wiring
5.1.1 Compliance
Installation of this equipment must be in accordance with all local, state and federal regulations pertaining to
this type of equipment including, but not limited to, the National Electrical Code, NFPA No. 70 and the
Automotive and Marine Service Station Code, NFPA No. 30A.
5.1.2 Wire Type
All wiring should have a capacitance rating of less than 100 picofarads per foot.
5.1.3 Probe Wiring
Gas and oil-resistant shielded, 2-conductor cable is required to extend the probe cable to the I.S. Interface
Module in the Controller. OPW Fuel Management Systems recommends you use Belden #88760 or Alpha
#55371 cable.
Belden #88760 is available directly from OPW Fuel Management Systems; part #12-1300
5.1.4 Sensor Wiring
You can use the same cable as used for the probe or you can use individual gas and oil-resistant cable,
providing it is 18 AWG or greater.
5.1.5 Wire Length
Wire runs must be less than 300 m (984 ft) to meet intrinsic safety standards. Also, wire lengths of 300 m (984
ft) or more between probe/sensor and the controller will jeopardize signal integrity and system operations.
5.1.6 Wire Splices
There should be no splices between the field junction box and the I.S. Interface Module in the SiteSentinel®
iTouch™ Controller. A splice in the hazardous area requires the use of a silicon-filled wire nut that must be
located in a waterproof junction box. Each splice would jeopardize signal integrity and system operations.
Page 23 of 123
8 Product Float and Water Float Offsets
The 924 probes differ slightly in setup from previous models of probe. This section tells you how to match your
manual dipstick tank readings to the readings from the probe. Offset compensates for the angle (or slope) that
the tank may have.
When performing subtractions, remember that subtracting a negative number is the same as adding the
positive version of that number. For example, subtracting -2 from 6 results in 8.
8.1 Offset Procedure
An example appears below:
1. Run the SiteConnect™ software. Set both the Product Float Offset and the Water Float Offset held
in the SiteSentinel® iTouch™ Controller to zero (0).
2. Using your normal dipstick access point in the tank, take a Dipstick Product Level and a Dipstick
Water Level. To take the Dipstick Water Level, use water detect paste on the bottom of the dipstick.
3. Take an inventory reading from the controller. Note the Probe Product Level and the Probe Water
Level.
4. Calculate Product Float Offset and Water Float Offset:
5. Product Float Offset = (Dipstick Product Level - Probe Product Level)
6. Water Float Offset = (Dipstick Water Level - Probe Water Level)
7. Run SiteConnect™ software and configure the SiteSentinel iTouch Controller with the new offset
values obtained in the previous step.
8. Take an inventory reading from the controller. The Probe Product Level should now match the
Dipstick Product Level and the Probe Water Level should now match the Dipstick Water Level.
A typical Product Float Offset is 7.4 cm (2.9 in) and a typical Water Float Offset is 0 cm.
8.1.1 Float Offset Example
Sample DIPSTICK Levels
Product = 59.5
Water = 1.2
Sample PROBE Levels
Product = 56.6
Water = 1.5
Using this data and this equation: Dipstick Product Level = Probe Product Level = Product Float Offset,
the product offset value is 59.5 - 56.6, or 2.9.
Using this data and this equation: Dipstick Water Level - Probe Water Level = Water Float Offset, the water
offset value is 1.2 - 1.5, or -0.3
Page 28 of 123
9 Probes
This section covers gasoline and diesel probes. For information on the optional LPG (liquefied petroleum gas)
probe, see Appendix F - LPG Probe Option on page 91.
9.1 Probe Floats
The terms “float” and “level indicator” are completely interchangeable.
9.1.1 Product Level vs. Water Level
Figure 9-1 on page 31 shows how the probe components work together. The Product Level Indicator floats
atop the gasoline or diesel fuel and registers the overall height of the fuel. You can use the Product Level
Indicator with or without a Water Level Indicator.
The Water Level Indicator features one of two different ballast weights (color-coded for gasoline or diesel - see
Figure 10-1 on page 33). Because fuel products are less dense than water, the weight plate forces the Water
Level Indicator to sink through the product and float on the water. Water height at the product/water boundary
can thus be determined.
9.1.2 Water Float Weight Specification
If you ordered a Water Level Indicator the weight and fluid product group will be on a label affixed in the area
below. Each weight is certified by an OPW Fuel Management Systems technician for use with its Water Level
Indicator. The listed weight is the complete weight of the level indicator.
9.1.3 Installing the Float(s)
1. Review Figure 9-1 on page 31.
2. Remove the retaining ring from the probe shaft.
3. Install the level indicator(s) as shown.
4. Make sure the Water Level Indicator (if used) magnet faces UP.
5. Install probe end boot.
6. Make sure the Product Level Indicator magnet faces DOWN.
7. Replace the retaining ring through the slot in the probe end boot.
If the wrong type of water float is used, it may float to the top and register an unusually high water level,
not register at all or sink too far and register an unusually low water level. If your product fluid density
does not fit into one of these groups, contact the OPW Fuel Management Systems customer sales
department for recommendations.

the other end of the shield. Do NOT allow the shield to touch any of the probe wires OR the metal
junction box.
Step-by-Step Procedure
1. Feed the blue probe cable through the bushing in the riser cap.
2. Attach the cable connector to the socket in the probe head.
3. Carefully lower the probe into the riser pipe until it rests on the bottom of the tank. Be careful not to
damage the floats.
4. Tighten the riser cap bushing, leaving enough cable to reach the junction box.
5. Snap the riser cap in place. Secure the cap with a lock.
6. Install a 13 mm (0.5 in) NPT bushing into the junction box.
7. Pass the probe cable through this bushing into the box, and then tighten the bushing.
8. Pull the shielded cable through the rigid conduit and through the installed seal-offs at both ends of the
conduit run. Leave slack in the probe wiring emerging from the ends.
9. Using the silicon-filled wire nuts included with the probe, connect the blue probe cable to the shielded
cable inside the electrical junction box.
10. Remove the clear plastic cover located over the I.S. Interface Modules inside the SiteSentinel®
iTouch™ Controller to attach the wiring from the probe conduit.
11. Connect the braided SHIELD from the Belden cable to the I.S. Module GROUND position.
12. Connect the BLACK wire to the I.S. Module SIGNAL position.
13. Connect the RED wire to the I.S. Module POWER position.

13.2.8 2nd IS Module Position - Water
1. Configure the barrier position to be a generic sensor (or if using SiteConnect™ choose the appropriate
icon) and install that position.
Set the upper alarm threshold to 0.5 volts.
2. Set the lower alarm threshold 0 volts (disables lower threshold).
3. Program the alarms associated with the upper threshold that you wish to activate if the sensor detects
water.
13.2.9 Testing and Decontaminating the Interstitial Hydrocarbon Liquid/Water
Sensor
When working in the hazardous area use caution to avoid a hazardous situation.
When testing or decontaminating the sensor, work in a well-ventilated area with no hot surfaces or open
flames. If the SiteSentinel® iTouch™ Controller fails to detect alarm conditions simulated here, also check that
your controller thresholds are correct.
Testing the Hydrocarbon Liquid Sensor Portion. Immerse the polymer in mineral spirits for about
10 minutes. Remove the sensor and let it hang to air dry. After another 10 minutes any controller
alarms or events associated with the hydrocarbon sensor should trigger. Disconnect this portion of the
sensor from the controller - an alarm should result. Short across these controller positions - an alarm
should also occur. If the open lead and/or short lead test fail, check all wiring and junction boxes for
continuity.
Testing the Water Sensor Portion. Immerse just the end of the sensor in tap water. Controller alarms
or events associated with the water portion of the sensor should trigger. Short the water portion of the
sensor - an alarm should occur. If the short lead test fails, check all wiring and junction boxes for
continuity.
Cleaning the Hydrocarbon Sensor Portion. To clean hydrocarbon contamination from the sensor
from testing or actual use, immerse the contaminated portion in denatured alcohol for one hour. Then,
flush the sensor with water to remove any residue. Leave the sensor to “settle” for another hour. The
sensor should return to nearly its original resistance, but it may be necessary to readjust the
controller’s thresholds.

13.4 30-3210-06, -10, -15 Hydrocarbon Liquid/Water Sensor
13.4.1 About the 30-3210-nn
The hydrocarbon liquid/water sensor is used primarily in monitoring wells with
fluctuating groundwater tables or in 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.
Figure 13-5 Hydrocarbon
Liquid/Water Sensor
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.

13.6 30-3221-1 Single-Level Sump Sensor
13.6.1 About the 30-3221-1
The single-level sump sensor is designed to detect the presence of liquid in
sumps, dispenser pans and other locations where the presence of a liquid
could indicate that a leak has occurred.
This sensor can also be used to monitor wet wells to ensure that liquid is
normally present. The sensor contains a float switch that activates in the
presence of liquid. In the event of a break in the cable, the system will activate
the alarm.

SiteSentinel® iTouch™ capabilities by letting you connect as
many as eight (8) output devices to the SiteSentinel®
iTouch™ Controller. The OM4 Output Module
communicates with the controller via a single-wire
communication port. Up to two (2) OM4 Output Modules
can be connected for a total of eight (8) output devices.
A common Output Module application is to turn off a
submersible pump when low product is detected in the tank.
Or, use it to activate an audible alarm when high product is
detected in a tank.
See SiteConnect™’s Online Help to program the alarms or
events and to associate them with the Output Module.
DO NOT connect the OM4 Output Module directly to a
submersible pump! The OM4 Output Module controls pumps INDIRECTLY, through relays or contactors.
High voltages exist inside the OM4 Output Module. Only qualified technicians should open the unit.
Before working on the OM4 Output Module, disconnect all power, including power to and from the
relays.
Output relays in the OM4 Output Module are not intrinsically safe! Do not PLACE PROBE AND/OR
SENSOR WIRING IN CONDUIT THAT CONTAINS WIRING FOR DEVICES CONNECTED TO THE OM4
Output Module.
23.1 Codes
 Relay wiring is classified Class 1 wiring.
 Installations must be in accordance with the National Electrical Code (NFPA No. 70) and the
Automotive and Marine Service Station Code (NFPA No. 30A). The installer is responsible to

Complete steps 4 and 5 by following local regulations and tank manufacturer recommendations.
4. Apply a sealant (not included) approved for LPG use to the threads of the flange.
5. Firmly tighten the flange to the LPG tank for a proper seal.
The following 3 steps are for 30-B-xxx probe ONLY
 Carefully slide the supplied shrink tubing over the probe outer shaft. Make sure it covers the entire
probe shaft.
 Cut the tubing, leaving an extra 2.5 cm (1 in) at the bottom of the probe.
 Carefully heat the shrink tubing using a heat gun or similar approved device until the tubing seals
around the probe. Be careful to not over-heat the tubing or it will split.
When shrinking the tubing at the bottom of the probe carefully bond the tubing towards the bottom of
the probe to ensure that the bottom of the probe is covered.
The following step applies only to the Q0400-xxx probe
This probe does not need the shrink tubing.
6. Go to the next step. Remove the protective cap from the open end of the probe fixture assembly.
7. Gently insert the probe into the probe fixture opening. For SiteSentinel® probes, make sure the shrink
tubing is not damaged during this process.
8. Be sure the probe is completely seated in the bottom of the probe fixture.
9. Make all electrical connections using instructions supplied with the probe. Inspect the head cover
assembly BEFORE you complete the electrical connections.
The remaining steps apply to the probe head cover ONLY
The probe head must be covered. Purchase a cover from OPW, order part number 30-1512 (Figure 24-3 on
page 92). You can cut the cover for clearance, but make sure you leave room for connections and cable
(Figure 24-4 on page 93).
1. Insert the cable through the bushing.
2. Insert the connector end of the probe cable into the threaded hole on the top of the head cover.
3. Thread the bushing into the hole on the top of the head cover.
4. Tighten the bushing with the lower molded nut (not the top compression nut).
Do not over-tighten the nut! It isn’t necessary for the bushing to be flush with the top of the head cover.
5. Pull just enough cable through the bushing so that the cable extends from the bottom of the head
assembly.
6. Tighten the compression nut to seal the fitting to the cable.
This completes the LPG probe installation.

25 Appendix G - Probe Comparison
25.1 Model 924 and 924B Magnetostrictive Probe Probe Comparison
Starting in October 2006, OPW Fuel Management Systems began switching from the Model 924
magnetostrictive probe to Model 924B probe. While taking on a new physical appearance, the Model 924B
probe is fully backward compatible with all SiteSentinel® family ATG consoles, as illustrated below:
 Compatible with all current SiteSentinel® family ATG controllers
 Same installation procedures, including wiring, I.S. barrier, floats and cable
 Same configuration procedures
 Capable of EPA 0.1 GPH (0.38 liter per hour) and 0.2 GPH (0.76 liter per hour) leak detection
 Both certified to UL/US/Canada, ATEX and, additionally on the model 924B, IECEX
While fully backward compatible with the Model 924, the 924B is engineered with the following improvements:
 Available EPA 0.1 GPH (0.38 liter per hour) leak detection now third-party certified with 2 in (5 cm)
diameter floats
 All stainless-steel construction (stainless-steel probe head and probe shaft)
 Conformal-coated circuit board with 100% Surface Mount Components
 Smaller overall head diameter - .2 in (3 cm) diameter - and shorter probe head - 8 in (20 cm) long
25.2 Ordering the New Probe
As for order entry, the same probe length calculation is kept while changing the model/part number from 30-
EAxxx to 30-Bxxx. For example, if ordering a probe for a 4 ft (122 cm) diameter tank, instead of part number
30-EA053 for a 924 probe, you should now order 30-B053. Other probe sizes, and their part number
correlation, are shown in Table 21 below:

25.3 Probe Installation
 Riser: as the new 924B probe head is 1 in
(2.54 cm) shorter than the 924 Probe, there
will be slightly more installation clearance
within any given riser (see Figure 25-1
below)
 Wiring: The 924B probe must be installed
using Belden 88760 cable terminating on
the same cable connector at the head
 Configuration: The configuration process
remains the same as current 924 probes.
For details, please refer to a SiteSentinel®
iTouch™ 2 or 3 installation manual and/or
SiteConnect™ software help file.
All 924B probes will be shipped out from the
Figure 25-1 924 vs. 924B Probe Head
factory with two plastic stabilizers installed. Should there be
any reason to reinstall the plastic stabilizers and the E-Clip
retainers, please do the following:
1. Twist white plastic stabilizer to open it and slide it onto
the top of the probe head, butting it up against the end of
the probe head as shown (See Figure 25-2).
2. Starting at the bottom of the probe, slide on an E-clip all
the way up the probe shaft until it locates in the grove
directly below the top stabilizer as shown in Figure 25-3
(You will need to push the clip past the lower two grooves
on the probe head that are used to locate the second
Figure 25-2 Top Stabilizer
stabilizer).
3. Slide the second E-Clip up the probe shaft and locate it in
the second of the two grooves found on the probe head,
twist a second stabilizer onto the probe head and butt it
up against the E-Clip. Finally, slide a third E-Clip up the
probe shaft and locate it into the groove as shown in
Figure 25-4, clamping it between the two E-Clips.
4. Put on the clip at the bottom of the probe head.
