Site Consid era tion s National Electrical Code Compliance

National Electrical Code Compliance

The following information is for general reference and is not intended to replace recommended National Electric
Code (NEC) procedures. It is important for the installer to understand that electrical equipment and wiring located
in Class I, Division 1 and 2 installations shall comply with the latest appropriate articles found in the National
Electric Code (NFPA 70) and the Automotive and Marine Service Station Code (NFPA 30A), or other local code
such as the CEC, Canadian Electrical Code.

PROBE-TO-CONSOLE WIRING

Shielded Cable or Veeder-Root Direct Burial Cable Required

To ensure the best operating systems available, Veeder-Root REQUIRES the use of shielded cable for all probes
regardless of conduit material or application. In these installations, shielded cable must be rated less than 100 pF/
foot (100 pF/304 mm) and be manufactured with a material suitable for the environment, such as Carol
or Belden

™

88760, 876 0, o r 8770.

Note: Throughout this manual, when mentioning any cable being used for probe-to-console wiring, it will be
referring to shielded cable.

Wire Length

Improper system operation could result in undetected potential environmental and health hazards if the probe-to­console wire runs exceed 1000 feet (304 m). Wire runs must be less than 1000 feet to meet intrinsic safety
requirements.

™

C2534

Splices

Veeder-Root recommends that no splices be made in the wire run between a probe junction box and the console.
Each splice degrades signal strength and could result in poor system performance.

Wire Gauges - Color coded

•

Shielded cable must be used in all installations. Probe-to-console wires should be #14 - #18 AWG (2.5 to 0.8

2

) stranded copper wire and installed as a Class 1 circuit. As an alternate method when approved by the

mm
local authority having jurisdiction, #22 AWG (>0.3 mm

2

) wires such as Belden 88761 may be suitable in

installations with the following provisions:

- Wire run is less than 750 feet (228 m)

- Capacitance does not exceed 100 pF/foot (100 pF/304 mm)

μ

- Inductance does not exceed 0.2

•

Total cable length per installation: 22,000 feet (6700 m).

H/foot (0.2 μH/304 mm)

POWER WIRING

2

Wires carrying 120 or 240 Vac from the power panel to the console should be #14 AWG (2.5 mm
for line, neutral and chassis ground (3); and #12 AWG (4 mm

2

) copper wire for barrier ground (1).

) copper wire

PROBE JUNCTION BOXES

Weatherproof electrical junction boxes with a gasketed cover are required on the end of each probe conduit run at
the manhole location. Gasketing or sealing compound must be used at each entry to the junction box to ensure a
waterproof junction. The interior volume of each junction box must be a minimum of 16 cubic inches (262 cm

3

).

Veeder-Root recommends the following junction box or equivalent:

•

Appleton Electric Co. - JBDX junction box, JBK-B cover, and JB-GK-V gasket.

•

Crouse-Hinds Co. - GRFX-139 junction box, GRF-10 cover, and GASK-643 gasket.

Site Consid era tion s Probe Wi ring Safety Issues

Probe Wiring Safety Issues

WARNING

Probes operate in area s wher e flammabl e li quid s and ex plos ive v apors may be

present.

Improper installation may result in fire or explosion causing serious injury or

death.

Practice the following:

1. Read thoroughly and f ollow the instructions shipped with each probe.

2. Probe wiring must enter the consol e only thr ough their designated areas.

3. Power wires and condui t must not enter the intrinsically safe
compartment of the console.

4. Substitution of components may impair intrinsi c safety.

Wiring between the console and the probes is of limited electrical power so that there is insufficient energy to
ignite fuel. In the console, the low power probe wiring is considered intrinsically safe because it is physically
isolated from all high power wiring. To maintain the integrity of this safety feature probe wiring can not share the
same conduit with power wiring. In addition, probe cables can only enter the console through the designated
intrinsically safe area knockouts.

If the TLS-50 System is being retrofitted into a paved site, you can cut grooves in the pavement, run direct burial
cable to the probes, and then seal over the cable grooves, subject to approval of the local authority having
jurisdiction.

Before trenching, you should diagram all conduit runs between the console’s intended location and its deployed
probes. Your site diagram will help you calculate conduit and wiring lengths, and necessary quantities of junction
boxes, sealing boxes, clamps, brackets, etc.

Throughout this planning process and in the actual installation, you must follow all latest National Electric Codes,
and applicable federal, state, and local codes as regards conduit type, depth below grade, sealing, grounding,
wire capacities, direct burial (if permitted), etc.

Selecting a Console Location

WARNING

Explosive vapors or flammable liquid s could be pre sent near locations where
fuels are stored or being dispensed. The TLS-50 Console is not explosion
proof.

An explosion or fire resulting in serious injury or death, property loss and
equipment damage could occur if the console is installed in a volatile,
combustible or explosive atmosphere (Class I, Division 1 or 2).

Do not install this c onsole in a v olatile, comb ustib le, or e xplosiv e atmosph ere.

5

Site Consid era tion s Selecting a Console Location

Select a mounting location on the inside of any building. The console must be protected from severe vibration,
extremes in temperature and humidity, rain, and other conditions that could harm computerized electronic
equipment.

The equipment is designed to operate safely under the following range of conditions:

•

Temperature range 0 to 40°C - ( storage temperature range of -40 to +74°C).

•

A maximum relative humidity of 95% RH (non-condensing) at temperatures up to 40°C.

•

Console may be powered by either 120 or 240 Vac. A switchmode power supply automatically detects the
input voltage (no jumpers required).

•

Main supply voltage fluctuations not exceeding ±10%.

•

Pollution Degree Category 2.

•

Installation Category II.

Important! Consoles must be installed within the interior of buildings. They are not suitable for any external
location.

Ensure that the console is located where neither the console nor its associated cabling will be damaged by doors,
furniture, barrows, etc. Consider the ease of routing wiring, ducting, and probe cables to the console. Check that
the mounting surface is strong enough to support the console’s weight of about 4 pounds.

Important! If the unit requires cleaning, do not use any liquids, wipe only with a clean, dry cloth.

Mounting the Console

Figure 3 illustrates recommended console mounting. Install the console fastening devices to the mounting surface
using the hole pattern (6.7” x 5.7”) shown in Figure 4. Mounting screws up to 3/16” diameter may be used.

Install metal conduit (1/2” I.P.S.) between the console and the power panel. Figure 4 shows the three designated
knockouts (one each on top, left side, and bottom) through which power wiring can safely enter the console.

Probe Installation

Probe Manhole Installation

At each underground probe location, install a 14-inch (355 mm) minimum diameter approved manhole according
to the manufacturer’s instructions (Note: probes should be located at least 24 inches (610 mm) from the
submersible pump to avoid erroneous probe readings when the pump is running). Position the manhole so that
there is necessary clearance for junction box installation and wiring.

Determining Mag Probe Length for Installation in a Dedicated Riser

1. Measure the distance from the bottom of the tank to the top of the probe manway - this is the minimum probe
length (ref. Figure 6).

2. The probe canister must be within the riser pipe (minimum length of 10 inches [254mm]).

SPECIAL INSTRUCTIONS FOR UST’S WITH METAL RISER CAPS

If you are installing the metal cap and adapter ring, screw the ring onto the 4” riser until the gasket contacts the
pipe, then use a pipe wrench to tighten it an additional 3/4 turn. Push the cable through the metal cap and cord
grip, then clamp the cap onto the ring.

At sites that require installation of a riser adaptor (Phil-Tite M/F 4X4 or equivalent) at the top of the riser, do so
following the manufacturer’s instructions. Next screw the adapter ring from the Veeder-Root kit (

P/N 312020-952)

onto the riser adaptor by hand until the gasket contacts the sealing surface. Then use a torque wrench attached to
an appropriate strap wrench (K-D Specialty tools nylon strap oil filter wrench, or equivalent) and tighten the ring to
35 - 45 ft-lbs. Loosen the cord grip nut and push the cable through the metal cap and cord grip, then clamp the
cap onto the ring (see Figure 9).

Make sure there is a minimal amount of slack between the probe and cap, then tighten the cord grip nut until the
cable is held firmly. Push the end of the cable through the field J-box cord grip, then tighten that cord grip nut as
well. Splice and seal the wires in the J-box as shown in Figure 12.

Installing Field Wiring from Probes to TLS-50 Console

Two wiring run methods are commonly used for probes - Shielded wiring pulled through buried, sealed 1/2” rigid
conduit (discussed in the following paragraphs); or direct burial cable (discussed on page 15).

WARNING

Probes operate in areas where flammable liquids and explosive vapors may be present.
Improper inst all atio n may res ult in fir e or explo si on causi ng se rious injury or death.
Practice the f ollowing:

1. Read thoroughly and follow the instructions shipped with each probe.

2. Probe wiring conduit must not contain any other wires.

3. Probe wiring and conduits must enter the console only through their designated
areas ( se e Figure 4).

4. Power and communication wires and conduit must not enter the intrinsically safe
compartment of the conso le. (see Fi gure 4).

Buried Rigid Conduit

The preferred method, especially in new sites before driveway surfaces are paved, is to pull probe wiring through
buried 1/2” rigid conduit [Figure 10].

Figure 10. Example Probe Wiring Run in Buried Rigid Conduit

Pull shielded cable consisting of two conductors, color-coded #14-18 AWG stranded copper wire, between the
console and the junction box at each

probe location (do not gang wires together). Use single lengths of wire with

no splices to ensure optimum signal strength.

IMPORTANT! Maximum probe-to-console cable length is 1000 feet (305m).

Since wires for multiple probes may enter the console through a single conduit, it is recommended that you use a
different color-code for each wire or individually mark each wire to identify probe inputs. Also, if the intrinsically
safe wires enter the building in a wiring trough, only intrinsically safe wires (from TLS-50/-50C probes) can be in
the trough. Keep all low power (intrinsically safe) wiring physically isolated from high power wires in all wiring
troughs per the NEC.

SEALING FIELD CONNECTIONS

1. Pull the wires from the probe canister into the junction box. Pull two wires from the console through the seal-off
box and into the junction box.

2. Using wire nuts, connect the two wires from the probe to the two wires coming from the console. Be sure to
observe color codes or tags when making these connections. Figure 11 diagrams a typical probe field wiring
connection in the junction box.

3. Do NOT terminate drain wire at this location, ground drain wire at console only.

4. Seal wire nuts with epoxy sealant using one bag for two-wire nut connections (Figure 12).

5. Push the tie-wrapped, epoxy sealed bag into the junction box. Replace and tighten the junction box cover.

Direct Burial Cable - Probe to Console Field Wiring

An alternative to trenching through existing pavement is to use direct burial cable.

IMPORTANT! Maximum probe-to-console cable length is 1000 feet (305m).

Prior to installing direct burial cable with epoxy splices, consult with the local authority having jurisdiction. Use of
direct burial cable is only allowed in locations where local codes permit the use of buried cable.

The direct burial method requires grinding a 1/4” to 3/8” wide by 1-1/4” deep groove (adding 1/4” of depth for
each additional cable) in the pavement surface, laying Veeder-Root supplied direct burial cable down in the bottom
of the groove, laying an expanded polyethylene foam backer rod over the cable(s), and then a placing a 1/4” to 1/
2” bead of Veeder-Root recommended silicone sealant over the backer rod to within a minimum of 3/8” below the
pavement surface [see Figure 13].

If you decide to use the direct burial method, you should order the Veeder-Root Direct Burial Cable Preparation
Kit, P/N 848100-500.

WARNING

The equipment is used in location where lethal voltages and explosive vapors
or flammable fuels may be present.

Care must be taken when installing, servicing or replacing part s in the syst em
or serious injury or death from explosion, fire or shock may occur.

For this system:

1. Comply with the latest Nati onal Electric Code, feder al, state, and local
codes, and an y other a pplicab le safet y codes . In ad diti on, take necess ary
precautions during installation, service, and re pair to prevent personal
injury, property loss and equipm ent damage.

2. Refer servicing to trained and qualified personnel only.

3. Substitution of components may impair intrinsi c safety.

OFF

4. Be sure AC power is “Off” before opening the console panel cover and
connecting probe wires. Do not short any voltage across any barrier
terminal including probes.

Precautions To Follow When Connecting Probes to TLS-50 Console

To The Installer! You Must Read And Understand This Information.

INPUT/OUTPUT WIRING POSITIONS AND LABELING

In all cases, the devices wired to the console’s input/output terminal blocks must be recorded to prevent
improper replacement during installation or service. A circuit directory is listed below for this purpose.

During programming, the probes wired to each position are identified and stored in memory. If a probe is removed
and reconnected to a different set of input terminals after programming, the system will not properly recognize the
data being received.

Wiring Assignments

1. Identify all probe wires according to their terminal block location using the self-adhesive numbering labels

furnished. Accurately record on the circuit directory in Figure 14 the location of each probe as you attach
wires to the probe input terminal block.

2. Important! Once a device has been wired to certain terminals and the system has been programmed, the wires
from that device may not be relocated to other terminals without reprogramming the system.

System Setup Security

To protect against unauthorized access to system operation DIP switch 4 of SW1 on the Power Supply board lets
you lockout setup and diagnostic menus after making initial programming (for consoles w/display only). Consoles
are shipped from the factory with this switch in the open (disabled) position.

See Figure 15 for location of this switch. Figure 16 shows the switch in the closed position, enabling setup
lockout. Switch 2 and Switch 3 are not used and can be in any position.

Overfill Alarm Relay

All consoles except those having form numbers 8469X0-060 and 8469X0-230 have one dry contact relay output
that closes when an overfill alarm is activated. You can connect an external audible/visual warning device to this
relay.

Important! Note these Output Relay Connection Restrictions:

1. Do not connect output relays to a device that draws more than 2 amperes of current. Output power: output
relay contact, resistive load - 120/240 Vac, 2 A max.

2. Alarm relays cannot be used for flow control. Alarm relays provide only a momentary closure and cannot
actuate flow control devices such as valves and pump motor relays for extended periods of time.

RS-232 Communications

The RS-232 port, provided with consoles having form numbers 8469X0-260, -230, and -460, connects to a user­selected serial printer, modem or terminal.

RS-232 Peripheral Equipment Requirements

Any peripheral equipment connected to an RS-232 serial port must meet the following criteria:

1. Peripheral equipment must be UL listed.

2. The equipment must have an EIA standard RS-232C or RS-232D communications protocol.

3. The equipment must NOT be installed over or in a hazardous location.

RS-232 Connections

TO A DEVICE LESS THAN 50 FEET FROM THE CONSOLE

Veeder-Root recommends that you use a null-modem cable no longer than 50 feet for direct connections between
the console and a remote device. Cable runs longer than 50 feet can result in data errors, component damage, or
both.

TO A DEVICE MORE THAN 50 FEET FROM THE CONSOLE

If cable runs longer than 50 feet are needed, two short-haul modems should be used, one at the console and one
at the remote device. We recommend an asynchronous short-haul modem, Black Box model ME800A, or
equivalent at the console and at the remote device. For more information, you can contact Black Box by phone:
724-746-5500, Fax: [phone], or web: http://www.blackbox.com

Figure 18 illustrates how to connect two short-haul modems between the console RS-232 Interface Module’s or
Auxiliary RS-232 Interface Module’s DB-25 connector and the remote device.

having form numbers 8469X0-260, 230, & -460). If enabled, the default serial security code is 000000. The
security code itself can be changed with a serial command (see “Function Code: 504” on page 31). Consoles are
shipped from the factory with this switch in the open (disabled) position.

See Figure 15 on page 17 for location of this switch. Figure 19 shows the switch in the closed position, enabling
the security feature.

Switch 2 and Switch 3 are not used and can be in any position.

DB-9 Connector Pin-Outs

Communicating with the Console from a remote computer is done through a RS-232 serial port (DB-9 connector)
on the bottom of the console.

Pin layout to connect the Console’s Serial Interface DB-9 connector to a 25-pin computer terminal connector are
shown in Figure 20. These connections are standard for “AT” style modem cables.

2. Attach the anti-static strap to your wrist and to a good ground.

3. Disconnect the CPU cable from the Power Supply board.

4. The CPU board snaps securely into place in the door of the console without the use of screws. There are two
tabs on the top of the board that fit into two slots in the top edge of the door. The bottom of the CPU board
snaps in place between two pairs of detents protruding from the bottom edge of the door. The CPU board is
removed by inserting a straight-slot screwdriver into one of the two indents on the bottom of the board and
then gently prying against the door until the board clears the upper detents, then rotating the board up slightly
and toward you to clear the top tabs from the slots in the door.

5. Replace the CPU board reversing the above steps.

6. Follow the cold boot instructions beginning on page 20.

the chip correctly if you insert the chip in the socket
with its angled corner in the same angled corner of the
socket.

3) Carefully align the chip's pins with the socket's pins.
(If you have the pins aligned correctly, the chip will seem to
drop into the socket.) Then push down firmly and evenly
on the chip until it snaps into the socket.

4) Check to see that all pins are in place and none are bent.

Troubleshooting Replacing the Power Supply Board

Replacing the Power Supply Board

The Power Supply board must be replaced when:

•

Probe data is not being processed, or

•

The voltage between the GND and 8V test points [Figure 24] on the back of the CPU board is less than 7 Vdc.

OFF

1. Turn Off power to the system.

2. Disconnect the CPU cable from the Power Supply board.

3. Tag and disconnect probe, power, and overfill alarm relay wiring to the Power Supply board.

4. The Power Supply board is secured by two T-15 Torx screws in the top of the board. For consoles with the com
option (see Table 1 on page 1), the two screw locks which go through the bottom of the console into the DB-9
connector must also be removed before you can lift out the board.

After removing the Torx screws (and screw locks), slowly lift up on the board until the lower tabs on the board
clear the slots in the bottom of the console, then continue to lift the board out.

5. Replace the board by reversing the above steps.

6. Turn on power to the system. The system will perform a warm boot procedure [page 21] and the display will
return to the top level status screen. You do not have to reprogram the console after replacing the Power
Supply board.
