Dear Customer,
Dear Engineer,
You are about to mount a SICK LinCoder® System.
These operating instructions are intended to give you the knowledge which is
necessary for you to be able to carry out the mounting rapidly and correctly.
Please read these instructions through carefully and pay particular attention to the
advice and warning notes!

Foreword
The LinCoder® System from SICK is a contactless, absolute length measuring system.
The measuring system is suitable for length measurement up to maximum of 40 metres,
both indoors and outdoors under normal ambient condition.
The measuring system comprises at least two parts:
– the scale
– the sensor
Scale
The scale – referred to below as the magnetic strip – comprises a magnetized plastic
strip which, at the factory, is laminated to a (ferromagnetic) steel strip.
The plastic strip contains the absolute length information magnetized on in the form of a
12-bit code.
Sensor
The sensor substantially comprises a rectangular aluminium housing
with a flanged plug or PG outlet.
In the application, the sensor is guided over the magnetic strip.
The sensor registers the information magnetized onto the magnetic strip and
from this determines a defined absolute length value.
The absolute position data are transmitted from and by the sensor to a control system or
to a host computer.
If you have any questions in relation to the LinCoder
answer them.
The telephone number will be found on the inside front cover of these operating
instructions.

General Advice
2 General Advice
2.1 Validity
These operating instructions apply to the LinCoder® L 230 contactless,
absolute length measuring system.
The configuration of the length measuring system is specific to a customer, that is to
say the syste
measured length.
2.2 Proper use
The LinCoder® L 230 length measuring system may be used only for the purpose
corresponding to its design – the determination of length or distance information.
Any further use or use going beyond this counts as improper and may lead to
personal injury or damage to property.

Safety Advice
3 Safety advice
3.1 Personal protection
The LinCoder® System operates exclusively with safe low voltages and, because of its
low inherent weight, represents a virtually negligible potential hazard. Nevertheless, the
measuring system may pose a threat in conjunction with further devices, machines or
plant.
Therefore, please observe the following advice:
Switch off all the devices/machines/plant affected by mounting
Depressurize pneumatic/hydraulic devices/machines/plant before mounting or
If necessary, set up warning signs in order to prevent the inadvertent starting
or repair.
If appropriate, isolate the devices/machines/plant from the mains.
repair.
up of the devices/machines/plant.
Do not under any circumstances start up the length measuring system
– with faulty safety equipment and/or
– with damaged components/modules (for example damaged plug connectors).
In these cases, isolate the system from the mains.
Ensure that, during the defect or the repair, the system cannot inadvertently be
connected to the mains. If necessary, set up warning signs.
After completing the repair work, carry out a test run of the system and check
the correct functioning of the safety equipment.
Observe the relevant professional safety and accident prevention regulations
when carrying out the mounting/repair work.
Prevent hands or fingers being able to get between sensor and magnetic strip, if
necessary by means of covers or the like.
Check the correct function of the safety equipment (for example the emergency
off push buttons) of the higher-order devices/machines/plant at regular intervals.

Safety Advice
3.2 Device safety
The LinCoder® System is a quality product produced in accordance with the recognized
industrial regulations and meets the quality requirements of ISO 9001.
The system left the manufacturing plant in perfect condition with regard to safety.
In order to maintain this condition, as installer you must carry out your task in accor-
dance with the descriptions in these instructions, technically correctly and with the
greatest possible precision.
In addition, we assume that you have sound knowledge in mechanical, precision engineering and electrical engineering.
Use the length measuring system only for the purpose corresponding to its de-
sign.
Switch off the devices/machines/plant affected by mounting.
If appropriate, isolate the devices/machines/plant from the mains.
Depressurize pneumatic/hydraulic devices/machines/plant before mounting.
If necessary, set up warning signs, in order to prevent inadvertent starting up of
the devices/machines/plant.
Take care, for example in the case of long mounting lengths, that no parts of the
plant penetrate into the mounting area.
Lay the data cable from the sensor to the controller in such a way that it
– does not remain hanging during operation when moving over the measure-
ment length;
– is not crushed, kinked or otherwise damaged;
– does not run directly beside power lines or through relatively strong alternat-
ing electromagnetic fields.
In the case of electrical welding work which is carried out in the immediate vi-
cinity of the LinCoder
damage to the measuring system from high induced currents.
®
System, switch off its supply voltage, in order to rule out
Never open the housing of the sensor.
Opening the sensor impairs the functional reliability and leads to the
cancellation of the guarantee or guarantee claims.
Use only undamaged/fault-free tools and components for the mounting work.
Do not start up the LinCoder
®
System if any parts are damaged.
Following the mounting of the measuring system, and before releasing the
devices/machines/plant affected by it to the production process, carry out a test
run.
Avoid intense external magnetic fields acting on and ferromagnetic foreign
bodies (for example iron filings) being deposited on the magnetic strip.
