5Product Features
The EMSC2/LMSC2 is an incremental magnetic length measur-
ing system with 1 Vpp sine/cosine outputs. The sensor technology
and evaluation electronics are located in a compact housing,
which can be mounted horizontally or (if option L is ordered)
vertically to the magnetic tape.
The magnetic tape required for the measurement is glued onto a
flat surface with the supplied adhesive tape.
Depending on the version, a mounting distance of the sensor of max. 0.8 mm (EMSC) resp. max. 2.0 mm
(LMSC) to the magnetic tape must be observed.
The measuring system offers decisive advantages:
Measuring lengths theoretically unlimited
Resolution of EMSC: 2 mm = 1 signal period
Resolution of LMSC: 5 mm = 1 signal period
Very robust against contamination
Sensor/mounting position horizontal or (optional) vertical possible
Compact housing design and easy installation
5.1 Functional Principle
The basis of the magnetic incremental encoders consists of a scanning technology, which scans the north and
south poles on the coded magnetic tape and produces a single Sine/Cosine wave for each pole.
Depending on refinement of the interpolation, together with the pole distance of the magnetic tape, the resolu-
tion of the measuring system is determined. The evaluation circuit prepare the signals accordingly and output
them as sine/cosine waves (channels Sin+ / Cos+ and Sin−/ Cos−) with a level of 1 Vpp (see also 5.3
Representation of the Waveforms).
Figure 1: Magnetic tape
5.2 Magnetic Tape Variants
Depending on the selected measuring system (LMSC or EMSC) different ELGO magnetic tapes must be used:
The LMSC variant uses the ELGO magnetic tape type MB20-50-10-1-R with 5 mm pole pitch.
For the EMSC, however, the magnetic tape type MB20-20-10-1-R with 2 mm pole pitch must be used.
If the interpolation rates are higher than 200 when using the EMSC, we recommend using the high-
precision magnetic tape MB20-20-10-1-R-HG, which is available at an extra charge (refer also to sec-
tion 10.1 Accessories).

7.2 Installation of the Sensor
For mounting the sensor two M3 screws are required.
Observe the mounting tolerances stated in section 7.2.2.
7.2.1 Alignment of Sensor / Magnetic Tape
Since the active sensor surface is not in the center of the sensor housing, it should be ensured that the sensor
head is aligned and mounted such that the active sensor surface is in the middle of the magnetic tape. This is
achieved in a simple manner and without additional equipment. Just use the correct side of the sensor (see fig-
ure below) and install it flush with the magnetic tape.

7.3 Installation of the Magnetic Tape
NOTE External Magnetic Fields
The magnetic tape must not be influenced by external magnetic fields!
The magnetic tape must not come into direct contact with other magnetic fields (e.g. perma-
nent magnets, magnetic clamps, electromagnets, magnetic stands)! This may cause irrepara-
ble damage, which will compromise the measuring accuracy or even the functioning.
7.3.1 The Magnetic Tape MB20-20-10-1-R / MB20-50-10-1-R
In the standard case, the magnetic tape is delivered as described
It is installed by gluing it to the respective mounting surface.
The magnetic tape consists of 2 pre-assembled components:
A magnetized, flexible plastic tape (Pos. 3), which is connected with a magnetically conductive steel
tape as inference band (Pos. 4) and is supplied with an adhesive tape (Pos. 5).
A magnetized permeable cover tape (Pos. 1), which serves for the mechanical protection of the plastic
tape (not required for the measurement) and is supplied with an adhesive tape (Pos. 2).
Therefore a divergent tape structure and scope of delivery is also possible.
The cover tape is also available separately

7.3.2 Handling
In order to avoid tension in the tape, it must not be stretched, compressed or twisted.
It should be stored with the magnetized plastic tape to the outside (see Figure 8), the minimum bending radius
must be noted here
Figure 8: Handling
7.3.3 Processing hint for the gluing of magnetic tapes
Surface-Preparation: In order to guarantee optimal adhesion, all anti-adhesive contamination (e.g. oil, grease,
dust, separating agents) has to be removed using solvents with residue-free evaporation.
Suitable agents are ketones or alcohols. Typical solvents for cleaning the surface are a 50/50 isopropyl alco-
hol/water mixture or heptane. Those agents are offered by Loctite and 3M among others as surface cleaners.
When using solvents, always observe the manufacturer instructions! If the surface is copper, brass etc., it should
be sealed to avoid oxidation.
Contact-Pressure: The strength of the adhesion is directly dependent on the contact the adhesive can form with
the surface. Therefore it is important to use as much pressure as possible when gluing the tape, possibly by us-
ing aids such as draw rolls. The optimum contact pressure is 4…5 kg/cm2).
Gluing temperature: The optimal gluing temperature is between + 18° C and 30° C. Avoid colder sticking sur-
faces than + 10°C, because in this case the adhesive becomes too hard and perhaps a sufficient immediate
adhesion is hardly to achieve. After proper sticking, the stability of the connection is ensured also when the tem-
perature is below zero. The final tackiness of a sticking is from experience reached after approximately 72 hours
(at + 21° C). For gluing use only the supplied adhesive tape.
7.3.4 Cutting and Gluing
Before starting the gluing process, both the magnetic and the cover tape have to be cut to the required length
Length cover tape = measuring length + sensor length + 50mm (end caps)
NOTE!
When sticking the magnetic tape pay attention to the markings on the tape and the Sensor.
Improper installation does not provide the correct values. A already glued magnetic tape is
destroyed after the removal, and cannot be used again. Note also the direction of counting
of the measuring system
Preferably the magnetic tape should be glued close to an edge or into a groove, which
should be deep enough to embed the magnetic tape and the cover tape.
When unprotected, the cover tape may peel off!
Therefore: Use tape end caps (10.1) or let the cover tape overlap the end of the magnetic
tape and fix it with a screw.

Steel tape

Installation and First Start-Up

The tape must be glued smoothly on the surface. The measuring accuracy decreases if the tape is not even!
Before gluing the magnetic tape and the cover tape onto the surface, they should be left lying on the mounting
surface for ca. 30 minutes so that the temperature matches. This prevents strain in the tape due to thermal ex-
pansion.
Mounting steps:
1. Thoroughly clean surface (7.3.3)
2. Acclimatization: let magnetic tape and cover tape adjust their temperature
3. Remove the protection foil from the magnetic tape
4. Glue magnetic tape under great pressure
5. Thoroughly clean surface of magnetic tape
6. Remove the protection foil from the cover tape
7. Glue the cover tape under great pressure
8. Safeguard the ends of the cover tape against peeling off, e.g. by using end caps (10.1)

9Disturbances, Maintenance, Cleaning
This chapter describes possible causes for disturbances and measures for their removal. In case of increased disturbances, please follow the
measures for fault clearance in chapter 9.1.
In case of disturbances that cannot be eliminated by following the advice and the fault clearance measures given here, please contact the
manufacturer (see second page).
9.1 Fault Clearance
CAUTION!
The device, the connection line and the signal cable must not be installed next to sources of interference that emit
strong inductive or capacitive interference or strong electrostatic fields.
External perturbations can be avoided thorough suitable cable routing.
The screen of the signal output cable should only be connected to the following circuit on one side. The screens
should not be grounded on both sides. Signal cables always have to be routed separately from the load power line.
A safety distance of at least 0,5 m has to be kept from inductive and capacitive sources of interference such as con-
tactors, relays, motors, switching power supplies, clocked controllers etc.!
If interferences occur in spite of all the items stated above being observed, please proceed as follows:
1. Installation of RC-circuits via contactor coils of AC-contactors (e.g. 0,1 µF / 100 )
2. Installation of recovery diodes via DC-inductors
3. Installation of RC-circuits via the different motor phases (in the terminal box of the motor)
4. Do not connect protective earth and ground
5. Connect a mains filter ahead of the external power pack
9.2 Re-start after Fault Clearance
After the fault clearance:
1. Reset the emergency stop mechanism if necessary
2. Reset the error report at the super-ordinate system if necessary.
3. Ensure that there are no persons in the danger area.
4. Follow the instructions from chapter 7.
WARNING!
Danger of injury through non-conventional fault clearance!
Non-conventional fault clearance can lead to severe injuries and damage of property.
Therefore:
Any work to clear the faults may only be performed by sufficiently qualified staff
Arrange enough space before starting the works
Make sure that the mounting area is clean and tidy. Loose components and tools are sources of accidents.
If components need to be replaced:
Pay attention to a correct installation of the spare parts.
Reinstall all the fixing elements properly
Before turning on the device, ensure that all covers and safety equipment is installed correctly and functions
properly
