SM5
Description
This manual describes the LD120 display and the
sensors of the SM5 series. The purpose of this
system is to display displacements on industrial
machines and automation systems. The
measurement system includes a LED display,
ma netic tape and a ma netic sensor. As the sensor
is moved alon the ma netic tape, it detects the
displacement which is shown on the display. The
flexibility of the tape allows it to be used for both
linear and an ular applications.

1 - Safety summary
We stron ly recommend carefully readin this user
manual and followin the installation uidelines:
•Measurement system (sensor) should be installed
as close as possible to the display.
•Always use shielded and twisted cables if
possible.
•Avoid runnin the sensor cable near hi h
volta e power cables (e. . drive cables).
•Install EMC filters on sensor power supply if
needed.
•Avoid mountin sensor near capacitive or
inductive noise sources such as relays, motors,
and switchin power supplies.
Connect accordin to the chapter 5: “Electrical
connections”.
2 - Identification
The display and sensor can be identified by the
label's data (orderin code, serial number). This
information is listed in the delivery document. For
technical features of the product to make reference
at the technical catalo ue.
3 - Installation
Install the product accordin to the protection level
provided. Protect the system a ainst knocks,
friction, solvents, and respect the environmental
characteristics of the device.
- Mounting steps

Mm/ich display modus can be chan ed by pushin
 key for 3 s.
6.2. Offset value modification
Push P and  keys simultaneously to display Offset
1 value (OFS1). Use  and  keys to chan e value
and save with * key. Further Offset values OFS2 and
OFS3 can be chan ed only in setup menu.
This function is enable only if “F_oFS” parameter is
set “on”.
 key allows to scroll OFS1, OFS2 and OFS3 values.

7 - RS 85 serial interface (option I )
If the display is provided with RS485 serial interface,
the followin commands can be used.
7.1 RS 85 parameters
Baud rate = 9600
Data bits = 8
Parity bit = No
Stop bit = 1
Flow control = Xon/Xoff
7.2 Serial commands
Serial commands must have the followin structure:
| A D C M N D = X
where :
| : PC keyboard symbol
AD : device address (00 to 31) 2 di it
CMND : command (see command list)
X : value ran e (see command list)
Upon receipt of a wron command the display will
answer with the same command + ? and checksum
(e. . sent command: |02azs → answer |02azs?EF)
Any common terminal pro ram can be used for
communication with LD120 (e. . Hyperterminal).
Command will be send after confirmation by ENTER
key (carria e return).
Answers are structured as follow:
ADCMND:SXXXXXCK
where:
AD : device address
CMND : command
XXXXX : value
CK : checksum
The checksum is equal to the least si nificant byte
of the summin the hex values of all characters
transmitted.
Example:
The displayed position is 8,29. The position of device
with address 01 is read by means of the |01TPOS
command.
The answer is: 01TPOS:+008290F
The sum of hex values of all characters is the
followin : 30+31+54+50+4F+53+3A+2B+30+30+
38+ 32+39 = 30F
The least si nificant byte of 30F is 0F which is the
checksum.
