Preliminary information
This guide is designed to provide the most complete information the operator needs to correctly and
safely install and operate the LD210 touch-screen indicator series.
LD210 touch-screen indicator is designed to interface analogue encoders.
It is equipped with two 16-bit analogue inputs and connects current (0 … 20 mA, 4 … 20 mA) and
voltage (-10 … +10 V, 0 … 10 V) analogue encoders. It can show process values from input 1 or input B
ad even the result of a variable combination of the inputs (sum, difference, …). Among the available
functions are tare, separate totalization, linearisation over 24 interpolation points, choice of the
engineering unit, sampling time setting, etc.
It features a touch screen and 7-segment graphic display with a complete set of plain text, symbols and
units. The LED display is bright and provides high contrast readability and also allows the background
light to turn red, green or yellow in the event of the set occurrences such as when the threshold limits
are exceeded. The combination of plain text and touch screen functions make the parametrization very
user-friendly and intuitive.
In the series the following models are available:
•LD210 touch-screen indicator standard version;
•LD210-PM provides additional 115-230Vac power supply;
•LD210-AVI provides additional 16-bit analogue output, four control outputs and RS-232 serial
interface;
•LD210-DO further offers four control outputs and RS-232 serial interface;
•LD210-RO is equipped with two relay outputs.
All options (-PM, -AVI, -DO, -RO) can be freely combined.
For technical specifications please refer to the product datasheet.
To make it easier to read the text, this guide can be divided into two main sections.
In the first section (from section 1 to section 4) general information concerning the safety, the
mechanical installation and the electrical connection.
In the second section (from section 5 to section 8) both general and specific information is given on the
operator menu and the setup procedure.
Operational modes
All functions can be configured in the parameter menu.
The device can be set to one of the following operation modes:
•SINGLE (only input A is used), see the Operational mode parameter in the “6.2 General menu”
section on page 34.
◦Single channel operation of input 1

•DUAL (input A and input B are both used), see the Operational mode parameter in the “6.2
General menu” section on page 34.
◦Two channel operation of input 1 and input 2
•IN 1 + IN 2 (input A and input B are both used), see the Operational mode parameter in the “6.2
General menu” section on page 34.
◦Two channel operation resulting from the addition of input 1 to input 2 (sum)
•IN 1 – IN 2 (input A and input B are both used), see the Operational mode parameter in the “6.2
General menu” section on page 34.
◦Two channel operation resulting from the subtraction of input 2 from input 1 (difference)
•IN 1 x IN 2 (input A and input B are both used), see the Operational mode parameter in the “6.2
General menu” section on page 34.
◦Two channel operation resulting from the multiplication of input 1 by input 2
(multiplication)
•IN 1 / IN 2 (input A and input B are both used), see the Operational mode parameter in the “6.2
General menu” section on page 34.
◦Two channel operation resulting from the division of input 1 by input 2 (division)
