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.
The complete sine/cosine signal process is interpolated electronically. Depending on refinement of the interpola-
tion, together with the pole distance of the magnetic tape, the resolution of the measuring system is determined.
The pole pitch of the magnetic tape MB20.20 and the suitable MR magnet rings is 2.0 mm. Special evaluation
electronics are used to process the sinusoidal signal. It generates rectangular output signals from the signal infor-
mation of the magnetized tape or ring, which are compatible with conventional rotary encoders or optical linear
measuring systems.

7Installation and First Start-Up
CAUTION
Please read the operating manual carefully before using the device! Strictly observe the Installation instructions!
In case of damage caused by failure to observe this operating manual, the warranty expires.
ELGO is not liable for any secondary damage and for damage to persons, property or assets.
The operator is obliged to take appropriate safety measures.
The first start-up may only be performed by staff that has been trained and authorized by the operator.
7.1 Operating Area
WARNING!
Do not use the device in explosive or corrosive environments! The device must not be installed close
to sources of strong inductive or capacitive interference or strong electrostatic fields!
CAUTION!
The electrical connections must be made by suitably qualified personnel in accordance with local regulations.
The device may be designed for switchboard mounting. During work on the switchboard, all components must be de-
energized if there is a danger of touching the energized parts!
(protection against contacts)
Wiring works may only be performed in the de-energized state!
Thin cable strands have to be equipped with end sleeves!
Before switching on the device, connections and plug connectors have to be checked!
The device must be mounted in a way that it is protected against harmful environmental influences such as splashing
water, solvents, vibration, shock and severe pollution and the operating temperature must not be exceeded.
7.2 Installation of Magnet Rings
The magnetic ring can be mounted on the axle or shaft either as a thermal fit or by bonding.
7.2.1 Recommended Adhesive
For bonding the magnetic ring to the shaft, we recommend the use of Loctite AA 326 adhesive with
pre-treatment by Loctite 7649 activator.

Installation and First Start-Up

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
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 (see Figure 6: Components of the magnetic tape:
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. The minimum bending radius is 150 mm.
Figure 7: 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 alcohol/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.
Magnetized
plastic tape
Steel tape

Installation and First Start-Up
- 16 -
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 the 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 clear-
ance 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 Ω)
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:
