It is intended to be installed into a machine or system. Flawless function in accordance with the specifications in the technical data is ensured only when using original BALLUFF accessories. Use of any other components will void the warranty. Opening the transducer or non-approved use are not permitted and will result in the loss of warranty and liability claims against the manufacturer. 2.2 General safety
4 notes for the position measuring system
notes for the position measuring system Installation and startup may only be performed by trained specialists with basic electrical knowledge. Qualified personnel are those who can recognize possible hazards and institute the appropriate safety measures due to their professional training, knowledge, and experience as well as their understanding of the relevant conditions pertaining to the work to be done. The operator is responsible for ensuring that local safety regulations are observed. In particular, the operator must take steps to ensure that a defect in the position measuring system will not result in hazards to persons or equipment. If defects and unresolvable faults occur in the position measuring system, take it out of service and secure against unauthorized use. 2.3 Explanation of the warnings Always observe the warnings in these instructions and the measures described to avoid hazards. The warnings used here contain various signal words and are structured as follows: SIGNAL WORD Hazard type and source Consequences if not complied with Measures to avoid hazards The individual signal words mean: NOTICE! Identifies a hazard that could damage or destroy the product. DANGER The general warning symbol in conjunction with the signal word DANGER identifies a hazard which, if not avoided, will certainly result in death

BTL housing: Housing containing the processing electronics. Fastening: The BTL transducer can be fastened in a fitting bore (Ø 48 H8), but must be sealed with the provided O-ring and support ring. The body of the transducer is fastened using 3 M5 threaded pins at a 120° angle. The transducer with Ø 10.2 mm has an additional thread at the end of the rod to support larger nominal lengths. Magnet: Defines the position to be measured on the waveguide. Magnets are available in various models and must be ordered separately (see Accessories on page 11). Nominal length: Defines the available measuring range. Rods with various nominal lengths from 50 mm to 2000 mm are available depending on the version: – Ø 10.2 mm: Nominal length from 50 mm to 2000 mm – Ø 8 mm: Nominal length from 50 mm to 1016 mm Damping zone: Area at th

A magnet is moved along the waveguide. This magnet is connected to the system part whose position is to be determined. The magnet defines the position to be measured on the waveguide. An internally generated INIT pulse interacts with the magnetic field of the magnet to generate a torsional wave in the waveguide which propagates at ultrasonic speed. The component of the torsional wave which arrives at the end of the waveguide is absorbed in the damping zone to prevent reflection. The component of the torsional wave which arrives at the beginning of the waveguide is converted by a coil into an electrical signal. The travel time of the wave is used to calculate the position. Depending on the version, this information is made available as a voltage or current output with a rising gradient. Mounting surface O-ring Support ring 7 4.1 Installation guidelines Fig. 4-1: Inst

Horizontal assembly: If installing horizontally with �nominal lengths 500 mm, we recommend tightening the rod at the end (only possible with Ø 10.2 mm) or supporting it. Hydraulic cylinder: If installed in a hydraulic cylinder, ensure that the minimum value for the bore diameter of the support piston is complied with (see Tab. 4-1). Fitting bore: The BLT transducer can be fastened in a fitting bore (Ø 48 H8), but must be sealed with the provided O-ring and support ring. The body of the transducer is fastened using 3 M5 thread

nued) 4.4 Shielding and cable routing Defined ground! The transducer and the control cabinet must be at the same ground potential. Shielding To ensure electromagnetic compatibility (EMC), observe the following: – Connect transducer and controller using a shielded cable. Shielding: Braided copper shield with minimum 85% coverage. – Cable version: On the transducer side, the cable shielding is connected to the housing. Ground the cable shielding on the controller side (connect with the protection ground). – Strand version: Observe note on shielding (see page 7). Magnetic fields The position measuring system is a magnetostrictive system. It is important to maintain adequate distance between the transducer/holding cylinder and strong, external magnetic fields. Cable routing Do not route the cable between the transducer, controller, and power supply near high voltage cables (inductive stray noise is possible). The cable must be routed tension-free.

position measuring system is part of a closed loop system whose parameters have not yet been set, the system may perform uncontrolled movements. This could result in personal injury and equipment damage. Persons must keep away from the system's hazardous zones. Startup must be performed only by trained technical personnel. Observe the safety instructions of the equipment or system manufacturer. 1. Check connections for tightness and correct polarity. Replace damaged connections. 2. Turn on the system. 3. Check measured values and adjustable parameters and readjust the transducer, if necessary. Check for the correct values at the null point and end point, especially after replacing the transducer or after repair by the manufacturer. 5.2 Operating notes – Check the function of the position measuring system and all associated components on a regular basis. – Take the position measuring system out of operation whenever there is a malfunction. – Secure the system against unauthorized use. 10 6.1 Accuracy The specifications are typical values for the BTL6-P510… at 24 V DC and room temperature, with a nominal length of 500 mm in conjunction with the BTL BTL magnet.
