Site Considerations

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 picofarad per foot and be manufactured with a material suitable for the environment, such as Carol

8760.

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-to-console wire runs exceed 1000 feet. Wire runs must be less than 1000 feet to meet intrinsic safety requirements.

™

C2534 or Belden™ 88760,

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 stranded copper

wire and installed as a Class 1 circuit. As an alternate method when approved by the local authority having jurisdiction, #22 AWG wires such as Belden 88761 may be suitable in installations with the following provisions:

- Wire run is less than 750 feet

- Capacitance does not exceed 100 pF/foot

- Inductance does not exceed 0.5 μH/foot

• Wires carrying 120 or 240 Vac from the power panel to the console should be #14 AWG copper wire for line, neutral

and chassis ground (3); and #12 AWG copper wire for barrier ground (1).

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.

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.

Probe Wiring Safety Issues

WARNING

Probes operate in area s wher e flammabl e l iquid s and ex plos ive v apors may be present.

Improper installation may result in fire or explosi on 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 through their designated a reas.

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

4. Substitution of components may impair intri nsic 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 f rom 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-HLD 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 wher e fuels are stored or being dispensed. The TLS-HLD 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 olati le, comb ustib le, or e xpl osive atmosph ere.

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).

Site Considerations Selecting a Console Location

• 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 switch-mode power supply automatically detects the input

voltage (no jumpers required).

• Main supply voltage fluctuations not exceeding ±10%.

• Pollution Degree Category 2.

• Installation Category II.

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 material is strong enough to support the console’s weight of about 4 pounds.

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

Console Installation

Mounting the Console

Figure 2 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 3. 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 3 shows the three designated knockouts (one each on top, left side, and bottom) through which power wiring can safely enter the console.

The following assembly instructions are for Global Mag Plus an Mag Plus probes. For other probe types follow assembly instructions included with probe.

Attaching Probe Canister Spacer Rings

1. Open the probe shipping carton so that you have access to the probe. Also open the installation kit.

2. After setting the spacer vanes for a 3- or 4-inch riser (see Figure 5), install the two spacer rings as shown. Note: you must slide the bottom spacer over the probe and onto the lower end of the canister. NOTE: spacers are not required for a 2-inch riser.

Assembling Floats onto Probe Shaft

The Product floats, Water Floats (if ordered), and Boots from Probe Installation Kits are assembled on the probe shafts in the exact

IMPORTANT! Failure to push the boot as far as possible onto the probe shaft could cause the boot and float(s) to fall into the tank. The boot must be pushed on until it “locks” on the probe shaft. Also, water floats must be installed, if ordered, for the probe to operate correctly.

Handle the probe carefully. Striking or dropping the probe will result in loss of calibration and could cause permanent damage.

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.

Probe Installation

Each probe supplied by Veeder-Root is accompanied by an assembly manual which details the assembly of the probe. Figure 7 and Figure 8 illustrate how to install the assembled probe either in an underground tank, and in an above ground tank.

Wiring Run Methods

Two wiring run methods are commonly used for probes - Shielded wiring pulled through buried, sealed 1/2” rigid conduit; or direct burial cable.

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 9].

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

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 (f rom TLS-HLD 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.

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

Probe Installation Pulling Wires for Probes

Splice closure

WARNING

Direct burial cable can be installed in hazardous locations where fuel and vapor may be present. It is specifically designed for certain uses only. It must be installed in the correct manner.

Installing the cabl e incorr ectl y or without pr oper precauti ons can resul t in fire, explosion, ele ctr ical shock, hazardous conditions as well as equipment damage or inaccurate inventory control.

Perform the following:

1. Use direct burial cable for intrinsically-safe wiring only. Do not use for power wiring.

2. Do not share conduit f or intr insica lly- safe p robes wi th wiri ng of an y oth er type or from any other system.

3. Maintain a physical separation of at least 2 inches between probe w iring to all other wiring.

4. When cutting trenches for direct burial cable ensure that you do not cut through exist ing fuel or wiri ng systems. Obtain as much site information as possible befor e cutting the trench.

5. When grinding trenches in existing pavement for direct burial cables, wear approved breat hing and hearing protection, goggles, and gloves.

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

Probe Installation Probe Wiring Precautions

Probe Wiring Precautions

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 13 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

RS-232 Communications

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 (15 m) 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 at - phone: 1-724-746-5500, fax: 1724-746-0746, or at their Internet address http://www.blackbox.com

Figure 15 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.

Connections to telephone lines must meet the following criteria:

• Connection to telephone equipment is subject to local regulations.

• Maximum short circuit current: 0 amperes.

• Maximum open circuit voltage: 0 volts.

RS-232 Communications Restricting System Programming Access

Restricting System Programming Access

To protect against unauthorized access to system operation, two security features can be enabled. These switches are located on the Power Supply Board next to the power wiring terminals (see Figure 16 below). Consoles are shipped from the factory with all switches in the open position.

SERIAL SECURITY

Enabling Switch position 1 allows the operator to enter a 6-digit security code before the system will respond to a serial command. The default serial security code is 000000. The security code itself can be changed with a serial command. However, the serial security code switch must be reset to the Open position to inhibit the security code requirement.

SETUP SECURITY

A switch in the console can be set to prevent access to the setup and diagnostic menus after initial programming. Closing or turning on Switch position 4 inhibits use of the setup and diagnostic menus.

Troubleshooting

This section contains information to help diagnose system problems. The Diagnostic Menu and Report can help determine if a probe is functioning correctly. The sections describing system boots help determine if the console hardware is functioning correctly.

A brief section is included that describes how install a software upgrade. Other sections detail CPU and Power Supply board replacement should the self-diagnostic programs indicate a hardware failure.

At the end of the Troubleshooting section you will find a list of specifications and a chart showing the probes that can be used with the TLS-HLD Console.

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 instructions in “TLS-HLD Cold Boot - Initial Power Up” on page 21.

Troubleshooting PROM Chip Replacement (Software Upgrade)

PROM Chip Replacement (Software Upgrade)

OFF

The PROM chip is replaced when a software upgrade is installed. This procedure requires that you perform a RAM clear.

1. If possible, record the current setup information. Turn Off power to the system.

2. Open the front door of the console. The CPU board is installed in the door.

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

4. Disconnect the CPU board cable from the Power Supply board. Remove the CPU board following the instructions in “Replacing the CPU Board” on page 48.

5. Locate the PROM chip on the board [Figure 19].

6. Remove the PROM chip following instructions in Figure 20.

7. Replace the PROM chip following instructions in Figure 21.

8. Replace the CPU board in the front door of the TLS-HLD. Connect the CPU board cable to J1 on the Power Supply board.

1) Orient PROM so that the small indented dot on top of the chip is on the same side with the small triangle embossed in the socket's base; or,

2) If the chip is covered with a label you can also orient 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 19] 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 and power.

4. The Power Supply board is secured by two T-15 Torx screws in the top of the board. You must also remove the two screw locks which go through the bottom of the console into the DB-9 connector 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.

Display Messages

TANK PARAMETERS

The following tank parameters are displayed one at a time as the operator scrolls through the Top Level Menu.

• Product Height,

• Product Temperature (requires probes that have temperature measurement capability),

• Water Height (requires probes that have water measurement capability).

Pressing the Tank key allows the user to select which tank's data is displayed. If a parameter is not available for any tank in the system, that display will not appear as you scroll through the menus. When viewing a display that is available in one of the tanks, but is not available for the current tank, a “

NO DATA” message will be displayed for that parameter.

Alarms

When an alarm occurs, the console’s internal beeper will activate (if enabled), the front panel LED will flash red, and the top line of the display will contain the alarm message. In the case of multiple alarms, the main display screen will automatically scroll through the active alarms. Press the Silent key to switch Off the internal beeper and acknowledge the alarm. The red LED will continue to flash until the alarm condition is remedied.

When an alarm condition returns to the normal state the alarm will be removed from the list of alarms. If no alarms are active, the LED will return to the Normal state (continuous green), the beeper will be switched Off, and the top line of the display status line will read ALL FUNCTIONS NORMAL.

Displayed Alarm Messages

• PROBE OUT (all probes) - If the console is not reliably communicating with the probe, the Probe Out alarm will

activate.

Troubleshooting Alarm Cause/Action Table
