1. Connections must be completed by only authorized personnel.
2. Consider the warnings when completing the connections and using the scale.
3. Pay attention about the sensors power supply. (For TTL sensor max. 5V, for Push-Pull sensor
max. 30V). Don’t energize the scale before all connections completed.
4. Distance between sensor and control unit must be short as possible. Avoid additions except
the suitable connector unless it needs.
5. Be away the sensor cable from high power cables, contactor, engine, or inductive and
capacitive noise sources.
6. The screen cable must be connected to the earth line.
7. The magnetic tape must be away from magnetic areas.
8. The proximity of the band with comparator, magnet or similar instruments having a magnetic
effect, disrupts the working structure of the band.
9. Don’t make any connection when the scale energized.
10.Please call the service for any problem about the scale.
11. Transport and storage should be at their original packaging and an ambient temperature of -
25°C / +85°C in such a way that they will not be exposed to dust, humudity, impact, vibration,
falling or water.
12. Chemicals such as alcohol, thinner etc. should not be used for cleaning the product. The
product should be wiped with a damp cloth.
13. The product may be damaged and may become unusable if used outside of the specifications
in the user manual. In this case, the product will be out of warranty.

These scales are used to achieve the best performance until the measurement up to 2040 in high speed and
vibrotary area. Thanks to the ıt’s montage point and design, the faults that are appear due to temperature variation
are minimized. On the other hand, the all precautions that is caused by machine are taken. Thanks to the Ergonomic
design , cable output don’t block the scale and works in a stability.
Thanks to the reference point, the side of the MLC 420 that is send by production as a left or right can be changed by
user.

4.1. Pin Connections
In the below table the cable color of the sensor
output signals is given. If the control circuit is
suitable in the Line Driver sensors the output
signal inverts (/A, /B, /Z) must be included in
the system. If the control circuit is not suitable
for this application /A, /B, /Z signal cables must
be immobilized seperately isolated. Don’t
forget that there are also currents on these
cables.

MLC 420, thanks to the movable reference point you can change the factory output directions. For example the
scales which is produced as right side can be return to the left side scale.
4.2. Reference Point Changing ( Right/ Left Changing )
For this operation a phillips screwdriver, a 1,5
mm allen, a 3 mm allen are needed.
The connector is detached by phillips screwdriver.
After detaching the connector open it by
phillips screwdriver to change the cable
direction..
Change the cable (1 ) and protection cover (2)
places. And close the connector.

The connector is put on its place. The screws is
closed again by Phillips screwdriver. Anymore
the cablo is on the other side.
The set screw screwdrivers of top installation
head are loosened with 3 mm allen and top
connection head is removed.
The top installation head that is removed is screwed
to the sensor’s other side with the help of the allen.
Reference determining’s set screw screws are removed to
change the reference point with 1,5 mm allen and drifted to
the other reference point. Set screw are squeezed again.
Anymore MLC 420 can be used as a
left scale.

Installation the MLC 420 is an important point in terms of the proper system function. The reader head is bearded in
the profile, the distance between the profile and reader head is constant. The parallelism between the reader head
and profile should stay same during the whole distances. The scale and reader head body should be set with the
proper equipments like comparator during the montage stage.
