3 For your safetyThe product is designed according to the state of the art technology. Residual hazards, howev-er, still exist. Observe the following warnings and safety regulations in order to prevent danger to persons and property. Turck accepts no liability for damage caused by failure to observe these warnings and safety instructions.

3.1 Intended use

The devices are designed for use in industrial automation applications. They only meet the EMC-requirements for these applications. The Ri360…-IOL rotary encoders with an IO-Link interface are used for measuring speeds and angle movements. To do this the devices detect mechanical rotary movements and convert them into a digital IO-Link telegram.The devices can be operated and parameterized via an IO-Link interface with IO-Link masters compliant with specification 1.1. Process and diagnostics data can be exchanged during opera-tion via IO-Link with the higher controller level.The devices must only be used as described in these instructions. Any other use is not in accor-dance with the intended use; Turck accepts no liability for any resulting damage.


Product description

3.2 Obvious misuse

Any use exceeding the maximum permissible speed of 800 rpm is not in accordance with the intended use. The devices are not safety components and must not be used for the protection of persons or property.

3.3 General safety instructions

■ The device must only be fitted, installed, set, operated and maintained by trained and quali-fied personnel.

4 Product descriptionThe inductive encoders of the RI360P-QR24 series measure speeds and angle movements up to 360º. The sensor and the positioning element of the encoders are fully encapsulated and there-fore designed as two independent and fully sealed units with protection to IP69K, which work together without contact. The optionally available adapter sleeves and mounting elements enable either the front or the rear of the encoder sensors to be fitted to shafts with a diameter of up to 20 millimeters. A mounting element for mounting on large rotatable machine parts is also provided in the program. The devices are available as absolute encoders with different output functions and also as incremental encoders. A robust stainless steel EQR24 variant is available for use in the food and beverage industry.The QR24 encoders with an IO-Link interface can be connected via a standard 4-pole male con-nector and a 3-wire connection cable. The devices can be operated and set via IO-Link.

4.1.1 Indication elements

The devices are provided with a green Power supply LED and a yellow Status LED.

4.2 Properties and features

■ Operation and setting via IO-Link ■ Single-turn, 16-bit resolution ■ Process value in 32-bit IO-Link telegram ■ 3 error bits ■ 13 multi-turn bits ■ 16 single-turn bits ■ Connection via 4-pole M12 × 1 male connector

4.3 Functional principle

The QR24 encoders have contactless operation based on the inductive resonant circuit measur-ing principle. This measuring principle makes it possible to design a fully encapsulated sensor housing without seals, which is separated from the positioning element. Magnetic fields cannot disturb the measuring process since the positioning element is not based on a magnet but on an inductive coil system, through which the sensor and the positioning element (resonator) can form an oscillation circuit. The inductive measuring principle of the QR24 encoder is absolute.

4.4 Functions and operating modes

The devices can be operated in IO-Link mode. The devices must be connected to an IO-Link master for operation in IO-Link mode.Different device functions can be configured via the IO-Link interface.

4.4.1 IO-Link mode

IO-Link mode provides bidirectional IO-Link communication between an IO-Link master and the sensors. For this the devices are integrated in the controller level via an IO-Link master. The switching signals are processed via the process data of the IO-Link interface. Besides the switch-ing information, diagnostics and identification messages can be queried via IO-Link.The following device parameters can be adapted to the particular application via IO-Link: ■ Device access protection ■ Rotation direction ■ Zero setting ■ Multiturn reset ■ Reset settings

10 TroubleshootingThe strength of the resonance coupling is indicated by an LED. Any faults are indicated via the LEDs.If the device does not function as expected, first check whether ambient interference is present. If there is no ambient interference present, check the connections of the device for faults.If there are no faults, there is a device malfunction. In this case, decommission the device and replace it with a new device of the same type.

11 MaintenanceEnsure that the plug connections and cables are always in good condition. The device is maintenance-free, clean dry if required.

12 RepairThe device must not be repaired by the user. The device must be decommissioned if it is faulty. Observe our return acceptance conditions when returning the device to Turck.

12.1 Returning devices

If a device has to be returned, bear in mind that only devices with a decontamination declara-tion will be accepted. This is available for download at http://www.turck.de/static/media/downloads/Declaration_of_decontamination_EN.pdf and must be completely filled in, and affixed securely and weather-proof to the outside of the packaging.

13 Decommissioning➤➤ Remove the connection cable from the power supply and/or processing units.➤➤ Remove the connection cable from the device.➤➤ Undo the connections of the device or if necessary the mounting aid for the mounting area.➤➤ Undo if necessary the connection of the device to the mounting aid.

14 DisposalThe devices are designed for installation in large-scale industrial installations and equipment. The devices must be disposed of correctly and must not be included in normal household garbage.
