1SafetyInstructions
1.1 Designated Use
AT1 analog transmitter is designed to be installed onto LT and LTC series level gauging systems. The device
transmits the level information into electric current, voltage, and resistance signals. It can also be equipped
with a maximum of six alarm contact signals.
In addition to transmitting the level, contact signals can be received by this transmitter alone, enabling easy
control of the valve and pump.
1.2 Installation, Commissioning, and Operation
•Mounting, electrical installation, start-up, and maintenance of the instrument may only be performed by
trained personnel authorized by the operator of the facility.
•Personnel must read and understand these installation instructions before performing 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 must be observed.
•The installer must make sure that the measuring system is correctly wired according to the wiring diagrams.
The measuring system must be grounded.
•Observe all law and regulations applicable and 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.

To highlight safety-relevant or alternative operating procedures in this manual, the following conventions have
been used, each indicated by a corresponding symbol on the left.
Safety Conventions
Warning!
Indicates an action or procedure that, if not performed correctly, will lead to personal
injury, a safety hazard, or destruction of the instrument
Caution!
Indicates an action or procedure that, if not performed correctly, may lead to personal
injury or malfunction of the instrument
Note!
Indicates an action or procedure that, if not performed correctly, may indirectly affect
operation or lead to an unexpected instrument response.
Explosion Protection
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 Areas
Symbol used in drawings to indicate explosion hazardous areas. Devices located in and
wiringentering areas designated as “explosion hazardous areas” must conform to 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 wiring enters into explosion hazardous
areas
Electrical Symbols
Direct Voltage
A terminal to or from which a direct current or voltage may be applied or supplied
Alternating Voltage
A terminal to or from which an alternating (sine-wave) current or voltage may be applied
or supplied
Grounded Terminal
A grounded terminal, that is already grounded by means of an earth grounding system for
the purpose of the operator
Protective Grounding (earth) Terminal
A terminal that must be connected to an earth ground prior to making any other
connection to the equipment
Equipotenial Connection (earth bonding)
A connection that must be made to the facility grounding system, such as a star-shaped
connection grounding system or equipotential line, according practices of the country or
company.
