1 Safety instructions

1.1 Designated use

The Float Tank Gauge LT11/12 have been developed for use in all areas of industry. Many years of operation

in wide variety of applications have proven their reliability. No electrical power is required to perform the mea-

surement.

Typical application:

• Level indication of petroleum products such as crude oil, kerosene, light and heavy oil, vegetable oil, palm

oil, seed oil and animal oil.

• Highly viscous liquid such as asphalt

• Certain chemicals (corrosive/toxic vapor can be sealed using liquid seal pot)

1.2 Installation, commissioning and operation

• Mounting, electrical installation, start-up and maintenance of the instrument may only be carried out by

trained personnel authorized by the operator of the facility.

• Personnel must absolutely and without fail read and understand this Operating Instructions before carrying

out its instructions.

• The instrument may only be operated by personnel who are authorized and trained by the operator of the

facility. All instructions in this manual are to be observed without fail.

• The installer must make sure that the measuring system is correctly wired according to the wiring diagrams.

The measuring system is to be grounded.

• Please observe all provisions valid for your country and pertaining to the opening and repairing of electrical

devices.

Caution!

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s

authority to operate the equipment.

1.3 Return

The following procedures must be carried out before the instruments is sent to Endress+Hauser for repair:

• Remove all residue which may be present. Pay special attention to the gasket grooves and crevices where

fluid may be present. This is especially important if the fluid is dangerous to health, e.g. corrosive, poisonous,

carcinogenic, radioactive, etc.

A copy of the “Declaration of Contamination” is included at the end of this operating manual.

Caution!

• No instrument should be sent back for repair without all dangerous material being completely removed first,

e.g. in scratches or diffused through plastic.

• Incomplete cleaning of the instrument may result in waste disposal or cause harm to personnel (burns, etc.).

Any costs arising from this will be charged to the operator of the instrument.
