Mag-FLEX Probe Length Calculation

Before ordering the Mag-FLEX Probe, an accurate dimension for “1” must be obtained. Measure internally the
Insertion Length of ‘1’ from the 1½” entry point to the bottom of the tank (see Figure 3). Probe length for ordering
purposes = Length of ‘1’ + 250 mm

Example Drawings Probe Handling

Probe Handling

It is important to handle the Mag-FLEX probe with care at all times during the installation. Avoid excessive bending
of the probe especially at the points the ridged sections meet with the flexible shaft. Below you can see examples
of mishandling that would cause irreversible damage to the probe and invalidate the terms of warranty.

15
 System Safety Layout

NOTICE Conduit/ducting requirements are dependent on local electrical regulations.

WARNING Substitution of components may impair intrinsic safety. Probe, probe wiring and con-
sole wiring are intrinsically safe only when connected via this barrier.

Field Cable Ducting / Cable Trays

WARNING Explosion could occur if other wires share ducts with intrinsically safe cir-
cuits. Ducting from probes or sensors must not contain any other wiring.

WARNING FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY PRECAU-
TIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT, RESULTING IN SE-
RIOUS INJURY OR DEATH.

Minimum diameters for underground probe ducting are:

• Up to 20 cables -100 mm diameter
• Up to 50 cables -150 mm diameter
Run suitable diameter cable ducting and / or cable trays from the TLS Console to each Mag-FLEX probe location.
For underground tanks, all cable duct entry points must be sealed to prevent the escape of hydrocarbon vapour and
liquid and the ingress of water. Cable duct & cable tray plans must be designed to suit local site requirements and
must conform to local/national regulations and industry standards.
For multiple TLS installations, the Mag Probe and Mag-FLEX cabling for one TLS system must be contained in
separate cable duct or tray to those cables belonging to another TLS system. Combining cables from different TLS
systems will be in violation of the intrinsically safe approval for this system and is not permitted. Combining cables
from different systems may also result in improper system operation.
Unless specified otherwise, any draw pits should be sited at 10 metre intervals or where acute cable duct angles are
unavoidable.
Ensure that all ducting is equipped with cable pull through ropes and that all visible cable ducts are properly fixed
and finished off in a neat and tidy manner.
All above ground cable runs should be properly secured and adequately protected from accidental damage.

Cable Specifications For Intrinsically Safe Apparatus Cabling

Cable must be installed to comply with local and national regulations in force at the time of installation. It is the
Installer’s responsibility to ensure that the installation complies with all relevant local and national legislation and
codes of practice.
Do not run the Mag-FLEX probe cable from the tank to the TLS Console in the same cable duct as non-intrinsically
safe wiring.
Gilbarco Veeder-Root requires the use of shielded cable for Mag-FLEX cabling. The cable must have a minimum
conductor CSA of 0.75 mm² and must meet with intrinsically safe system installation requirements. The cable
capacitance, inductance and L/R ratio must conform to the intrinsically safe output characteristics of the TLS
Console and the intrinsically safe input characteristics of the Mag-FLEX probe.
Field Cable, ATG to Probe, direct burial cable, V-R P/N 848100-2XX.

NOTICE The TLS Console to Mag-FLEX probe cable length must not exceed 300 meters.

Probe Installation Requirements

NOTICE The instructions herein are intended as reference material only, the Gilbarco Veeder-Root
training modules contain comprehensive information and must be completed before any
installation work is attempted - contact Gilbarco Veeder-Root for details.
Installation requires a minimum of two people to allow correct handling of the probe. Please note that the flexible
and therefore fragile nature of the Mag-FLEX probe makes it more prone to mechanical shock. The probe must not
be unpacked until it has been brought to its place of installation and where possible unpacked at the Tank top. The
probe corrugated shaft is supplied in a 1 meter diameter coil this coil MUST not be reduced in size. The packaged
curve is the maximum bend possible to prevent damage.

Mag-FLEX Installation & Handling Procedures TLS setup

TLS setup

The TLS console Mag-FLEX setup is similar to that for a standard Mag Plus Probe setup. Listed below are the
setup exceptions.

FLOAT TYPE
For TLS2, TLS-3XX or TLS-450 consoles, the float type must be set to 3” FLOAT (76.2 mm).
1. This is the default float type.
2. Water detection starts at 5.5” (140mm). Per the console’s programming, water height warnings and alarms
cannot be set above 5” (127mm), therefore when the float reaches 5.5” both the water warning and alarm will
be activated. (Program the console to any amount within the required thresholds of 0.87 to 5.0 inches (22.1 to
127mm).)

If a water reading of 5.5” or below is required, install the Low Level Water Float.
3. See manual 577014-056 for setup instructions when installing a low level water float.

TANK PROFILE
Select ‘Linear’ for TLS2, TLS-3XX or TLS-450 consoles, or ‘Multi-Point’ if an accurate tank chart is available.

TANK DIAMETER
For vertical cylindrical tanks, enter the full tank height here (NOT the diameter of the cylinder). Full height is the
distance from the bottom of the tank to the top of the cylinder excluding the domed lid at the top of the tank. Set
the height in mm.

Exit Setup Mode and check the inventory report, the water reading should now be “0”. Verify all TLS setup
parameters are correct. If necessary, secure all console doors.
