General, Safety, Transport and Storage Statement of Warranties The producer guarantees the functional capability of the process engineering and the selected parameters. Demounting and Disposal Unless acceptance and disposal of returned goods are agreed upon, demount the device considering the safety instructions of this manual and dispose it with respect to the environment. -
Page 8: Conventional Use
The product described in this manual was developed to execute safety-related functions as a part of an entire assembly or machineThe ELGO-device is only conceived for the conventional use described in this manual. The ELGO EMAX / EMAL linear encoders only serve to measure lengths. -
Page 9: Product Features
Product Features 5 Product Features The series EMAX / EMAL is an absolute length measuring system. Sensor and translator and interpolation unit are together in the same compact housing. The magnetic tape of series EMAB is paste up to a plain area. The EMAX / EMAL encoders can be mounted with a maximum distance of 1.5 mm to the magnetic tape. -
Page 10: Technical Data
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. When corresponding with ELGO always indicate this data. Dimensions Sensor Housing with Cable Outlet 14.1 22.5... -

Page 14: Installation And First Start-Up
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. -
Page 15: Installation Of The Magnetic Tape
Installation and First Start-Up 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. - Page 16 Installation and First Start-Up 7.2.2 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 must be noted here Magnetized Plastic tape...
- Page 17 Installation and First Start-Up 7.2.4 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.

Page 18: Installation Of The Sensor
Installation and First Start-Up Installation of the Sensor In order to fasten the sensor head, two M3 must be used. NOTE! The correct distance sensor / magnetic tape is monitored and displayed by the LED on the top resp. on the front sensor (depends on design). Distance not correct LED glow red The mounting tolerances given below are valid for both housing types (standard version with fixed cable outlet or sensor housing with round connector). -
Page 19: Offset Calibration
Installation and First Start-Up 7.3.2 Mounting Direction of EMAX / EMAL Sensor to Magnetic Tape Since the magnetic tape has two magnetized tracks, the sensor and magnetic tape must always be mounted in the correct direction in order to obtain correct measurement results. Marking arrows on the tape and sensor clearly indicate the correct mounting direction. -
