Safety instructions
The Brief Operation Manual for Safe Use contains safety instructions. For further information do consult the Operation and Installation Manual,
document no.: 550980, available on the Level Product CD, part no.: 550766 supplied with your level transmitter or cost free download at www.
mtssensors.com .
INTENDED USE
The Level Plus®Model USTDII liquid level transmitter is used for continuous measurement of product level, interface level, and/or temperature
of liquids in containers in hazardous areas.
INSTALLATION, COMMISSIONING AND OPERATION
• The liquid level transmitter may only be installed, connected, operated and maintained by trained technical personnel. The technical
personnel must strictly adhere to the Operating Instructions, prevailing standards, legal regulations and certificates (depending on
application).
• If the Brief Operating Manual for Safe Use does not provide sufficient information, you must read the Operation and Installation
Manual. There, you can find detailed information on the device.
• The operator may only perform direct replacement of like components manufactured by MTS that are explicitly permitted in the
Operating Instructions.
• Do not operate damaged products and secure them against unintentional commissioning. Mark the damaged product as being
defective.
• If faults cannot be rectified, the products must be taken out of service and secured against unintentional commissioning.
• The product is designed to meet state-of-the-art safety requirements, has been tested and left the factory in a condition in which it
is safe to operate. Relevant regulations and European standards have been observed.
• As the user, you are responsible for complying with the following safety conditions:
- Installation instructions
- Local prevailing standards and regulations
• Only use the product according to its specification.
SPECIAL CONDITIONS FOR USE IN EXPLOSION-HAZARDOUS AREAS
• Model USTDII sensors may only be connected to certified intrinsically safe circuits (Ex ia or Ex ib).
• The electronics housing is to be installed in zone 1 (category 2G, EPL Gb}. The sensor pipe/hose may be installed in zone 0
(category 1, EPL Ga} if not restricted below.
• Equipotential bonding shall be installed inside and outside the hazardous area along the cable for supply and data.
• Float usage:
- Metallic floats may only be used if they have a weight offset (asymmetric weight distribution).
- Metallic floats on non-metallic pipes may not be used.
- Aluminum floats may not be used.
• Plastic floats may only be installed in hazardous areas which require apparatus of category 1G (for zone 0} with explosion group IIA.
Plastic floats may not be used on non-metallic pipes.
• Sensors of type USTDII with fill tube hanger (inside the tank) are not ATEX approved for hazardous areas.

conditions are met:
• Uo of the barrier combination is less than Ui of the transmitter.
• Io of the barrier combination is less than Ii of the transmitter.
• Co of the barrier combination is greater than the total Ci of the transmitters plus the cable capacitance.
• Lo of the barrier combination is greater than the total Li of the transmitters plus the cable capacitance.
Transmitter entity parameters:
• Ui = 28 Vdc
• ∑li = 200 mA
• Ci = negligibly low
• Li = negligibly low
2. Power supply cable must be 0,22 mm2or heavier (e.g. 1.32 mm2AWG 16), shielded twisted pair cable. Cable capacitance
must be less than 160 pF/m. Cable shield is connected to system ground at safety barrier end only.
3. Communications cable must be 0.22 mm2or heavier (e.g. 1.32 mm2AWG 16), shielded twisted pair cable. Cable capacitance
must be less than 160 pF/m. Cable shield is connected to system ground at safety barrier end only.
4. The wire connection between earth ground and the safety barrier ground terminal must be less than 1 ohm.
5. Maximum approved number of DDA or MODBUS gauges for intrinsically safe wiring networks is 6 to 8. Contact factory for
Modbus applications.
6. Connection to earth ground for transient protection circuitry.
7. Ground screw earthing hardware provided to connect gauge housing to earth ground.
8. The transducer frame shall be grounded to earth ground directly or through the equipment on which it is mounted and shall be at
the same potential as the safety barrier ground electrode.
9. Electronic equipment connected to associated apparatus must not use or generate more than 250 volts RMS.

Floats
Model USTDII transmitters should be used with a float having an offset weight and made of stainless steel or Hastelloy C. This allows the float
to stay in contact with the pipe to prevent the buildup of electrostatic charge. For detailed information about floats, refer to the ‘Accessories
Catalog’, MTS part number 551103.
Non-metalic floats with a projected surface area of less than 5,000 mm² should only be used in Zone 0, Gas group IIA such as float part
numbers 201643-2, 201649-2, 201650-2, 201109, 251115 and 251116. All other non-metallic floats offered by MTS such as, 251939,
251119, 251120 and 252999, should not be used in a hazardous area application.
