3Product Features
The angle measuring system EMAX-RO is a combination of a sensor and a mag-
netic ring. The magnetic ring is mounted directly to an engine shaft or an axle
(see mounting suggestions 5.3). This ensures a quick and easy installation.
EMAX-RO is especially suited for measuring rotative angles.
The sensor head with high protection class is resistant against any kind of dust
and dirt and works completely without wear. Furthermore, the rotative measuring
system EMAX-RO has the advantage of absolute measurement and therefore
belongs in the category of single turn encoders.
Important features:
Rotative angle measuring system
Resolution of 16000 measuring steps over 360° (other resolutions on request)
Absolute measurement
Different interfaces are available
Absolute:
- Standardly: SSI or CANopen DS406;
- On request: RS422, addressable RS422, RS232, CAN BASIC ELGO
- In preparation: BISS-C
Incremental:
- 90° phase shifted square-wave signals TTL or HTL
- Sine/cosine signal 1Vss
Direct measurement on engine shaft or axle possible
3.1 Functional principle
A Hall sensor and a magneto-resistive impedance measuring bridge are guided over a two-track magnetic tape
with a fine-interpolation trace and an absolute trace. Together with the sensor line the absolute track provides
an absolute value and the fine-interpolation trace provides together with the interpolation electronic the measur-
ing systems high resolution. The figure shows two magnetic traces, with North Pole and South Pole magnetiza-
tion. The fine interpolation trace encloses alternately north and South Pole traces with a distance of 5 mm, these
are scanned with resistance bridges and provide a resolution of 16000 steps per turn. The absolute value pro-
vides the sensor line with 16 single Hall sensors. These sensors are scanning the code sections of the north and
south poles. The absolute value on the magnetic ring repeats once per revolution.
For easier illustration were the tracks of the magnetic ring shown as a tape

5Installation and First Start-Up
CAUTION
Please read the operating manual carefully before using the device! Strictly observe the In-
stallation 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 as-
sets.
The operator is obliged to take and to realize appropriate safety measures.
The first start-up may only be performed by staff that has been trained and authorized by the
operator.
5.1 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 interfer-
ence 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.
WARNING!
Influence of external magnets
External magnetic fields must not exceed 64 mT (640 Oe; 52 kA/m) on the surface of the
magnetic ring as this could damage or destroy the code on the tape.

5.2.3 Offset
After the installation of the magnetic tape and the measuring system (EMAX-RO) a value is transmitted by the
interface. Because this value does not conform to the machine zero point, an offset should to be deposited at
the controller side.
NOTE!
The offset should be arranged at any change from measurement system (sensor head) or
magnetic ring.
5.2.4 Activation of the device
The device starts automatically after operation voltage application. Depending on the interface may be addi-
tional steps required to activate the EMAX-RO.

6.2 Interfaces
The following chapters give detailed information about the connections and interfaces.
6.2.1 Interface SSI (option SB0 and SG0)
If the clock is not interrupted for the time Tm-T/2 (output of further 25 periods), the shift register clocks once
again the same data value (error recognition in evaluation).
Some encoders contain a Power Failure Bit (PFB):
With EMAX-RO the PFB is always „LOW“.

7Disturbances, 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 7.1.
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).
7.1 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
7.2 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 5.
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

7.3 Maintenance
The device is maintenance-free.
WARNING!
Danger through non-conventional maintenance!
Non-conventional maintenance can lead to severe injuries and damage of property.
Therefore:
Maintenance works may only be completed by staff that has been authorized and trained by the operator.
