LMT SERIES | MAGNETOSTRICTIVE LEVEL TRANSMITTER LMT100 & 200 MODELS | CI/LMT100/200-EN REV. B

Introduction

The LMT Series of level transmitters is a modular range of field

mounted, microprocessor-based electronic transmitters,

utilizing multiple sensor technologies. Accurate and reliable

measurement of liquid levels is provided in even the most

difficult and hazardous industrial environments. The LMT

Series can be configured to provide specific industrial output

signals, according to 4-20 mA with HART digital

communication. The LMT Series consists of two models:

LMT100 (insertion-mounted) and LMT200 (mounted on gauge

(KM26).

Standard Precautions

CAUTION

Only qualified and authorized personnel are to be tasked

with the installation, electrical connection, commissioning

and maintenance of the transmitter. Qualified personnel are

those individuals who have experience in the installation,

electrical connection, commissioning and operation of the

transmitter or similar devices and hold the necessary

qualifications. These qualifications include but not limited

to:

• Training or instruction – authorization to operate and

maintain devices or systems according to safety

engineering standards for electrical circuits, high

pressures and aggressive media

• Training or instruction in accordance with safety

engineering standards regarding maintenance and use of

adequate safety systems.

Since the transmitter may form a link within a safety chain,

it is recommended that the device be replaced immediately

if defects are detected. In the event of use in a hazardous

area, only non-sparking tools are to be used.

IMPORTANT NOTE

Read the LMT Series operating instructions carefully before

working with the product. For personal and system safety and

for optimum performance, make sure you thoroughly

understand the contents before installing, using or maintaining

this instrument.

3 Easy Setup

1 Log on to the LMT at the Standard or Advanced access level.

2 Select Easy Setup in the main menu.

3 Select a language in the “Easy Setup” menu and press .

4 Select available option of primary variable in the “Easy

Setup” menu and press .

5 Select available option of units of measure in the “Easy

Setup” menu and press .

6 Set LRV in the “Easy Setup” menu and press .

LRV is the lower range value which corresponds to 4 mA current

out value.

7 Set URV in the “Easy Setup” menu and press .

URV is the upper range value which corresponds to the 20 mA

current out value.

8 Set Damping time in the “Easy Setup” menu and press .

Damping allows smoothing step response in the device output.

9 Select displayed variable in the “Easy Setup” menu and

press .

Sets the selected process variable on the first line on the

process display.

10 Set a tag in the “Easy Setup” menu and press .

A tag is a quick way to identify the device.

*For detailed commission/operation steps refer to LMT

operating instructions.
