Safety Instructions

Safety instructions

The Brief Operation Manual for Safe Use contains safety instructions. For further information do consult the Operation and Installation Manual,

document no.: 550720, 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 MR 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.

Safety

Instructions

SPECIAL CONDITIONS FOR USE IN EXPLOSION-HAZARDOUS AREAS

• Model MR 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 with flexible measuring hoses:

- The hose has to be mechanically protected from external impacts which may affect its function as separation wall.

- Avoid kinking or bending the flexible hose in less than 16 inch (406 mm) diameter.

Floats

Model MR 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.
