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 7: Conventional Use
General, Safety, Transport and Storage Conventional Use The ELGO-device is only conceived for the conventional use described in this manual. The ELGO MTM-A-000 length measuring system only serves to measure positions, lengths and/or speeds. CAUTION! Danger through non-conventional use! Non-intended use and non-observance of this operating manual can lead to dangerous situations. Therefore: Only use the device as described ... -
Page 8: Product Features
Product Features 5 Product Features The MTM-A-000 measuring system is based on the physical principle of magnetism and is used for a high- precision determination of the position, the moved distance and/or the speed. Based on this wear-free and con- tactless absolute measuring system, MTM-A-000 is suitable for fixed round rod profiles - for example for non- rotating piston rods of hydraulic cylinders in mobile automation. -

Installation and First Start-Up 8 Installation 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. -
Page 14: Installation Of The Sensor
Installation and First Start-Up Installation of the Sensor 8.2.1 Alignment of the active Sensor Area In the case of a 10 mm or 20 mm wide, single-track coded rod, the sensor housing must be positioned so that the center of the sensor pitch line is in the center of the magnetic absolute coding. The center of the sensor pitch line is located at a distance of 5 mm from the outer edge of the sensor housing (see figure). -
Page 15: Adjustment Of Reading Distance And Lateral Offset
Installation and First Start-Up Adjustment of Reading Distance and Lateral Offset Depending on the order specification, a 10 mm or 20 mm wide single-track coding or a complete all-round coding is used. Since the magnetic field lines are differently pronounced with a narrower and wider coding, different maximum reading distances and lateral offset tolerances result for the mounting of the sensor to the round rod. -
Page 16: Calibration Of The Measuring Range
Installation and First Start-Up Calibration of the Measuring Range 8.4.1 Calibration for Versions with CAN Interface A hardware calibration as described in section 8.4.2 is not required for this version. The calibration of the upper and lower set point is performed via the CANopen interface. 8.4.2 Calibration for Versions with Analog Output REMARKS... - Page 17 Installation and First Start-Up 8.4.2.2 Teach Set Point 2 (Max) Move the round rod to the upper set point (e.g. maximum position) and release the TEACH button during the red phase. Set point 2 (Max position) 6 x flashing, followed by 6 x pressing button stores the upper set point. This is confirmed by the LED with a single green hold for 1.5 seconds.
