General, Safety, Transport and Storage 2 General, Safety, Transport and Storage Information Operating Manual This manual contains important information regarding the handling of the device. For your own safety and operational safety, please ob- serve all safety warnings and instructions. Precondition for safe operation is the compliance with the specified safety and handling instructions. -
Page 5: Statement Of Warranties
General, Safety, Transport and Storage Statement of Warranties The statement of warranties is enclosed separately in the sales documents. Guarantee: The producer guarantees the functional capability of the process engineering and the selected parameters. The period of warranty is one year and begins with the date of delivery. -
Page 6: Conventional Use
General, Safety, Transport and Storage Conventional Use The product described in this manual was developed to execute safety-related functions as a part of an entire assembly or machine. It is the responsibility of the manufacturer of a machine or installation to ensure the proper functioning of the system. The ELGO-device is only conceived for the conventional use described in this manual. -
Page 7: Product Features
Product Features 3 Product Features EMAX-HI is a magnetic length measuring system. Sensor and translator are integrated in one housing. The mag- netic tape is attached to a flat surface using the adhesive tape included in the delivery. EMAX-HI can be installed at a distance of up to 0.5mm from the magnetic tape (without cover tape). -

Technical Data 4 Technical Data Identification The type label serves for the identification of the unit. It is located on the housing of the sensor and gives the exact type designation (=order reference, see type designation) with the corresponding part number. Furthermore, the type label contains a unique, traceable device number. -

The LED- Indicator on the sensor housing flashs red, if this distance is exceeded. The direction arrow have to point in the same direction by the assembly. -
Page 13: Description Installation / Mounting Of The Magnetic Tape
Installation and First Start-Up Description installation / Mounting 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. - Page 14 Installation and First Start-Up 5.3.2 Handling In order to avoid tension in the tape, it must not be stretched, compressed or twisted. It should be stored or used with the magnetized plastic tape to the outside. The minimum bending radius is 150 mm. Magnetized plastic tape Steel tape...
- Page 15 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.

Connections and Interfaces Interfaces 6.4.1 SSI (Interface 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-HI the PFB is always „low“. - Page 18 Connections and Interfaces 6.4.3 RS422 (Interface Option 420) Depending on the order specification the encoder can be equipped with a RS422 interface (option 420). The data transmission has the following format: 9600 baud / 1 Start Bit / 8 Data Bits / 1 Stop Bit / No Parity Data protocol: The actual value is transmitted with the programmed Baud rate, 8 Data bits, 1Stop bit, without parity bit in the following format:...
