TLS Magnetostrictive Probes International Installation Guide Health And Safety
The Magnetostrictive Probe that is part of the TLS Monitoring System is equipment Category 1 intended to be
installed in a Zone 0 hazardous location. Extreme care must be taken when determining the suitability of the
installation conditions and operation of the TLS Monitoring System. Procedures for installing either in a process
connection or riser pipe are detailed beginning on
aid in the determination if a probe is to be installed in a process connection or riser pipe:
1. Equipotential grounding of the installation site,
2. Minimizing static hazards associated with the underground storage of flammable liquids, and
3. Protection of the system against lightning strikes and any other source of possible electrical surges caused by
electrical railway systems, high voltage direct current facilities and the like.
page 13. At least the following items must be considered and will
EQUIPOTENTIAL GROUNDING
Consult any local regulations prior to installing a Magnetostrictive Probe into any tank. Veeder-Root supplies
approved process connections for installations where direct connection between the probe body and tank structure
is required (see Probe Installation Using Process Connection instructions below).
The intrinsically safe circuit in the TLS Monitoring System is derived from a fuse protected zener diode intrinsic safety
barrier. This type of explosion protection requires that the intrinsically safe electric circuit is referenced to the safety
ground associated to the mains circuit. If the site has a submersible pump (DIN/EN 15268) connected to the same
mains safety ground as the TLS Monitoring System Console and it is installed in a metallic riser of a metallic storage
tank, the zener diode barrier must be referenced to the same earth (safety) ground.
MINIMIZATION OF ELECTROSTATIC HAZARDS
Consult any local regulations prior to installing a Magnetostrictive Probe into any tank. Veeder-Root supplies
approved process connections for installations where direct connection between the probe body and tank structure
is required (see Probe Installation Using Process Connection instructions below).
The magnetostrictive probe housing complies with the 500 volt electrical strength requirements in IEC/EN 60079-
11. In addition, the probe housing provides an electrostatic dissipative path to the zener diode barrier earth ground
that must be referenced to the common grounding system. The electrostatic resistive path is less than 1 megohm.
All TLS Consoles provide an alarm if either of the two wires to the magnetostrictive probe is disconnected or short
circuited due to a malfunction.
If a probe must be serviced or replaced, observe any required relaxation time prior to opening any covers and
removing the probe.
LIGHTNING AND SURGE PROTECTION
Consult any local regulations prior to installing a Magnetostrictive Probe into any tank. Local rules or regulations may
require surge arrestors when installing equipment that crosses from a less restrictive zone, e.g., zone1 to zone 0
independent of the risk assessment. When required Veeder-Root can supply appropriate surge protection devices.
In locations where the intrinsically safe cables or circuits are considered to be at risk of developing hazardous
potential differences within Zone 0, an external surge protection device may be needed. Perform the lightning risk
analysis to determine if surge protection is required, and if necessary, the surge protector shall be installed in
accordance with IEC/EN 60079-25 and IEC/EN 60079-14. Reference
locations for a surge protector.
When they are deemed necessary, Veeder-Root requires the installation of external surge protection devices that are
classified as simple apparatus only. Only gas-discharge type surge protectors that comply with Clause 12 of IEC/EN
60079-25 are acceptable. Additional installation requirements for surge protection devices are defined in Clause
12.3 of standard IEC/EN 60079-14.
The Surge Risk Protection Assessment checklist (SRPA) is available on the Veeder-Root Tech Docs CD and on our
website at http://www.veeder.com/page/Probe_Manuals. An example of the SRPA appears in Appendix A of this
manual.

EC-TYPE CERTIFICATES FOR AN INTRINSICALLY SAFE SYSTEM
TLS Monitoring Systems are installed according to the conditions specified in the applicable Certificates. ATEX
Certificate Number DEMKO 06 ATEX 137480X and IECEx ULD 08.0002X are referred to as the system certificate
or parent certificate for all of the equipment in a TLS Monitoring System.

TLS Magnetostrictive Probes International Installation Guide Before You Begin
Except for the cables used to connect intrinsically safe apparatus, information contained on the system certificate
and each of the device certificates, provide the safety related information (Ex ia) required to install a TLS
Monitoring System. Cables used to connect intrinsically safe apparatus must be considered in determining
compliance and are limited to the maximum allowable cable parameters listed in this manual. For assistance in
calculating the required (Ex ia) safety parameters, contact GVR as described on the inside cover of this manual.
For European Community (EC) installations, additional equipment compliance information is available on the EC
Declaration of Conformity including reference to the technical standards applied by the Notified Body in creating
the respective ATEX Certificates.
THESE ARE THE CONDITIONS FOR SAFE USE WHEN INSTALLING A MAG PROBE
1. The devices have been evaluated in conjunction with the intrinsic safety system defined in DEMKO 06 ATEX
137480X. The descriptive system documents and manuals included with the aforementioned certificate must
be followed during installation and the appropriate Veeder Root accessories must be used. Manual 577014031 details applicable process connections in accordance with EN 60079-26.
2. The following condition of safe use applies to the Mag Sump Sensor: Before installing or taking into a
hazardous area, earth the unit in a Safe Area to remove any static charge. Then immediately transport the unit
to the installation site; do not rub or clean the unit prior to installation. Cleaning is not required under normal
service conditions; do not rub or clean the device after installation. If the unit is not fixed to a known earth
point when installed, ensure that a separate earth connection is made to prevent the potential of static
discharge. When fitting or removing the unit, use of anti-static footwear & clothing is required.
3. The enclosure contains aluminum. Care must be taken to avoid ignition hazards due to impact of friction.
ATTENTION!
Important Considerations - Read Prior to Installation - Metallic/Steel Tanks
Process Connection (gland): Must be used in locations where it is mandatory that the Mag Probe be
equipotentially bonded to the tank structure.
Riser Pipe: May be used in locations that do not require bonding between the Mag Probe and the tank structure.
Reference European Norm IEC/EN 60079-14: Explosive atmospheres - Part 14: Electrical installations design,
selection and erection.
Cathodically Protected Tanks: Installation selection is dependent on the considerations listed above for the
Process Connection and the Riser Pipe.
Only install TLS Magnetostrictive Probes according to one of the four procedures listed below:
Wired Connections – Mag Probe to ATG Console wiring - see Figures 1 and 18.
1. Process Connection (gland) – Zone 1 installation, Surge Protector not required
2. Riser Pipe – Zone 0 installation, Surge Risk Protection Assessment (SRPA) required
Wireless Communication – Mag Probe with RF hardware - see Figures 2, 24 and 25
3. Process Connection (gland) – Zone 1 installation, surge protector not required
4. Riser Pipe – Zone 0 installation, Surge Protector required
Before You Begin
1. Consult any local regulations prior to proceeding to determine the best installation method. The instructions
below detail how to safely install probes with process connections or in a riser pipe and will also help in
determining when surge protection is required or may be necessary.
2. Depending on the considerations above, perform a Surge Risk Protection Assessment (SRPA) of equipment
in the site. A (SRPA) checklist is available on our website at http://www.veeder.com/page/Probe_Manuals.
3. Verify the equipment needed to complete the installation as described in this manual, and, if necessary, any
equipment required following completion of the site Surge Risk Protection Assessment (SRPA).
