1 Safety instructions
1.1 Designated use
Analog transmitter AT1 is designed to be installed onto LT and LTC series level gauging systems. The device
transmit the level information into electric current, voltage, and resistance signals. Also it could be equipped
with maximum of 6 alarm contact signals.
Along with the level transmission, contact signals can be received by this transmitter alone. Thus, the valve
and pump can easily be controlled.
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 these installation instructions before carry-
ing out the procedures..
• 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.
1.3 Operational safety
1.3.1 Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex documentation",
which is an integral part of this Operating Manual. Strict compliance with the installation instructions and
ratings as stated in this supplementary documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as pipe as national and local regulations.
Caution!
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.

conventions have been used, each indicated by a corresponding symbol in the margin.
Safety conventions
Symbol Meaning
Warning!
A warning highlights actions or procedures which, if not performed correctly,
will lead to personal injury, a safety hazard or destruction of the instrument.
Caution!
Caution highlights actions or procedures which, if not performed correctly,
may lead to personal injury or incorrect functioning of the instruments.
Note!
A note highlights actions or procedures which, if not performed correctly,
may indirectly affect operation or may lead to an instrument response which
is not planned.
Device certified for use in explosion hazardous area
If the device has this symbol embossed on its name plate it can be installed
in an explosion hazardous area.
Explosion hazardous area
Symbol used in drawings to indicate explosion hazardous area.
- Devices located in and wiring entering areas with the designation
"explosion hazardous areas" must conform with the stated type of
protection.
Safe area (non-explosion hazardous area)
Symbol used in drawings to indicate, if necessary, non-explosion hazardous
areas.
- Devices located in safe areas still require a certificate if their outputs run
into explosion hazardous areas.
Direct voltage
A terminal to which or from which a direct current or voltage may be
applied or supplied
Alternating voltage
A terminal to which or from which an alternating (sine-wave) current or
voltage may be applied or supplied
Grounded terminal
A grounded terminal, which as far as the operator is concerned, is already
grounded by means of an earth grounding system.
Protective grounded (earth) terminal
A terminal which must be connected to earth ground prior to making any
other connection to the equipment.
Equipotential connection (earth bonding)
A connection made to the plant grounding system which may be of type e.g.
neutral star or equipotential line according to national or company practice
