Introduction
This manual describes site preparation and installation procedures for the TLS-IB and Mag Probes. Site preparation is
divided into International and U.S./Canadian installations. The sections that describe how to connect probe, IFSF, and
Serial Comm wiring to the TLS-IB, and troubleshooting/maintenance procedures are common to all locations.
The TLS-IB is mounted in a non-hazardous area of the site and monitors up to eight in-tank Mag Probes located in the
hazardous area of the site.
This manual assumes that you installing the TLS-IB in a new site (before pavement is put down and with no wiring runs
in place). After the TLS-IB is installed, you should setup and configure the unit via the IFSF network.

DANGER AREAS
If the underground storage tank to be fitted with a TLS system either contains or at any time has contained petroleum
products then the tank inspection chamber must be considered a hazardous environment as defined in IEC EN 60079-10
Classification of Hazardous Areas. Suitable working practices for this environment must be observed.
INTRINSIC SAFETY
The design of Veeder-Root products limits the power in the wiring to the in-tank probes and keeps this wiring physically
separated from any other. It is the responsibility of the contractor to maintain the effectiveness of these safety features by
preparing the installation site in accordance with the instructions and warnings which follow. Failure to do so could
create danger to life and property.
Circuitry within the probe and console barrier forms an intrinsically safe, energy limited system. This system makes the
probes suitable for use in hazardous locations. Probe wiring is intrinsically safe only when connected to the TLS-IB unit.
IMPORTANT! Substitution of specified components may impair intrinsic safety.
All probe wiring must be contained in dedicated ducts.
Tank Lid Access Chambers
ACCESS CHAMBER INSTALLATION
The installation of the tank access chamber is the responsibility of the customer or their local site contractor and not that
of Veeder-Root Environmental Systems Limited. However, there are certain requirements which need to be met to allow
the correct installation of Veeder-Root in–tank monitoring probes. A typical installation is illustrated in Figure 2.
WARNING
TLS System products will be operated near the highly combustible
environment of a fuel storage tank.
Failure to install these products according to the instructions contained in this
manual may result in explosion and personal injury.
It is essential that the warnings and instructions in this manual are carefully
read and followed to protect both the installer and others from serious or
fatal injury.
WARNING
An explosion could occur if other wires share ducts with intrinsically safe
probe wiring. Ducting from probes must not contain any other wiring circuits.
Failure to comply with this warning could result in explosion, death, serious
personal injury, property loss or equipment damage.

.
Figure 2. Typical Tank Lid Access Chamber Installation
IMPORTANT! To allow adequate space for probe installation and servicing, it is recommended that the access chamber
is a minimum 750 mm deep and 600 mm wide at the base (see Figure 3 on page 7).
Veeder–Root are able to make special provision for tank lid access chambers of restricted depth. Contact your Veeder–
Root Account Administrator at the address given on page 4.
PROVISION FOR PROBE RISERS
A dedicated Probe tapping of either 2-inch BSP, 3-inch BSP (preferred) or 4-inch BSP must be provided. For maximum
height–to–volume accuracy, the probe socket must be as close as possible to the longitudinal axis of the tank.
IMPORTANT! The probe entry must not be obstructed by other pipe work. A free area above the probe socket of at least
100 mm radius from its centre must be provided. For Level 2 Installations probe entry plugs must be loosened and
readily removable. Failure to provide sufficient access or to loosen plugs will cause delays in system installation and
could result in additional charges.

Where mechanical overfill prevention devices are installed, contractors must ensure that no part of these devices
will be obstructed when the probe and riser assembly is installed. Failure to comply with this warning may result
in the overfill prevention device not operating correctly.
European Probe and Riser Installation Criteria (Non-PTB)
All Mag Probes require installation using a 3-inch riser, regardless of tank entry size. All entry sizes, other than 3 inches,
must be adapted to 3 inches with suitable fittings. The minimum probe entry size that can be used is 2 inches.
Where possible, the canister of the probe should be completely contained within the 3-inch riser. In all cases, the probe
must rest on the bottom of the tank (see Figure 4).
IMPORTANT! Incorrect readings will result if the probe is not resting on the bottom of the tank.
Figure 4. Typical Probe Installations
GENERAL NOTES
• 3-inch risers, when fitted, should be a minimum of 100 mm above the probe canister (see Figure 5).

• Wherever possible, the probe canister should be completely contained within the 3-inch riser. If this is not possible, a
probe sleeve kit must be used. Probe sleeve kits provide both electrical insulation and lateral stability for the probe
(see Figure 6).
Figure 6. Probe canister sleeve kit installation
IMPORTANT! When using probe sleeve kits, a minimum length of 75 mm of probe canister must be contained within
the 3-inch riser. Check also that the full safe working capacity of the tank can be measured by the probe chosen.
• Probes specified for tanks with entries smaller than 3 inches must always be long enough to rest on the tank bottom
and not ‘hang’ in the riser adaptor (see Figure 7).
Figure 7. Canister clearance for 2-inch entries
• Veeder-Root make special provision for tank lid access chambers of restricted depth. Contact Veeder-Root Technical
Support or your Sales Administrator for details on custom length Mag Probes and low profile riser kits, having the

DETERMINING THE MINIMUM ACCESS CHAMBER DEPTH
The minimum access chamber depth, is calculated as follows:
1. To the chosen Standard Probe Length (“H”), add 450mm, this is the overall probe length, enter this in column “I”.
2. From the Overall Probe Length subtract dimension “B + C” (bottom of tank to top of probe flange); the result is the
minimum access chamber depth. Enter in column “J”.
3. Calculate the actual access chamber depth, Dimension “E” minus dimension “C” and enter in column “K”.
4. Calculate the probe clearance (“K” – “J”) and enter in column “L”.
IMPORTANT! Column “L” must be zero or a positive number. If the result is a negative number contact your
Veeder–Root Account Administrator.
TLS-IB Location
The TLS-IB should be located on an inside wall of the forecourt building Be sure the console will be protected from
vibration, extremes in temperature and humidity, rain and other conditions that could cause equipment malfunction.
The equipment is designed to operate safely under the following range of conditions:
• Altitude up to 2000 m.
• Temperature range of 0 to 40°C.
• A maximum relative humidity of 95% RH (non-condensing) at temperatures up to 40°C.
• Main supply voltage fluctuations not exceeding +/- 10%
• Pollution Degree Category 2 Installation Category II
IMPORTANT! The TLS-IB unit must be installed within the interior of buildings.This unit is not suitable for any
external location.
Ensure that the TLS-IB is located where neither it nor its associated cabling will be damaged by doors, furniture,
barrows, etc. Consider the ease of routing wiring, ducting and probe cables to the unit.

Mounting the TLS-IB
Install the TLS-IB fastening devices to the mounting surface using the hole pattern 170 x 145mm (6.7 x 5.7 inches)
shown in Figure 12. Mounting screws up to 4.7mm (3/16-inch) diameter may be used.
Mount the TLS-IB to the mounting surface using the four mounting flanges on the back of the unit. Install ducting or
conduit between the TLS-IB and the power panel. Figure 12 shows the three designated knockouts (one each on top, left
side, and bottom) through which power wiring can safely enter the TLS-IB.
