For your safety
General safety notes

3 For your safety
The product is designed according to state-of-the-art technology. However, residual risks still
exist. Observe the following warnings and safety notices to prevent damage to persons and
property. Turck accepts no liability for damage caused by failure to observe these warning and
safety notices.
3.1 Intended use
The encoders of the RI360…-QR24… product series with incremental output are used to
measure speeds and angular movements. To do this, the devices record mechanical rotary
movements and convert them into electrical pulse sequences. Per revolution, a defined
number of pulses is emitted.
The devices may only be used as described in these instructions. Any other use is not in accord-
ance with the intended use. Turck accepts no liability for any resulting damage.
3.2 Obvious misuse
nThe devices are not safety components and must not be used for personal or property
protection.
nAny use that exceeds the maximum permissible mechanical speed (see technical data) is
deemed to be not in accordance with the intended purpose.
3.3 General safety notes
nThe device may only be assembled, installed, operated, parameterized and maintained by
professionally-trained personnel.
nIf safe operation can no longer be guaranteed: Shut down the device and lock out to prevent
accidental startups.
nThe device may only be used in accordance with applicable national and international regu-
lations, standards and laws.
nThe device meets the EMC requirements for industrial areas. When used in residential areas,
take measures to avoid radio interference.

4 Product description
The inductive encoders of the RI…-QR24… product series measure speeds and angular move-
ments up to 360º. The sensor and the positioning element of the encoders are fully potted and
designed as two independent and fully sealed units with protection to IP68K, which work
together without contact. The optionally available adapter sleeves and mounting elements
enable either the front or the rear of the encoder sensor to be fitted to shafts with a diameter of
up to 20 mm. 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 in-
cremental encoders. A robust stainless steel EQR24 variant is available for use in the food and
beverage industry.
The QR24 encoder with incremental output has a push-pull/HTL output with A-, A (inverse),
B-, B (inverse) and Z-track. The number of pulses per revolution can be freely parameterized
between 1 and 5000 for the RI…-QR24-INCR… devices with the PACTware FDT frame (FDT/
IODD). Alternatively, the nine most common pulse counts can be set from the easy teach-in
function of the encoder.

4.3 Operating 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.
To generate an incremental output signal from the absolute rotation angle, the sensor detects
the actual rotation angle per millisecond and from this calculates the resulting number of
pulses to be output.
4.4 Functions and operating modes
4.4.1 Output function
The output signal of the incremental encoder is based on the HTL interface (high transistor
logic). The inverted signals A (inverse) and B (inverse) are output in addition to tracks A and B.
A Z-track is also available.
The QR24 is an absolute encoder that calculates the pulses of a clock cycle and emits these
pulses according to the clock cycle within 800 µs. The cycle duration is therefore not inversely
proportional to the speed of rotation. The angle sensing for positioning is, however, carried out
exactly according to the number of output pulses.
The number of pulses output can be configured from 1 to 5000 for the RI…-QR24-INCR…
devices.
For the output signal evaluation, we recommend standard input cards or counter blocks that
can process a minimum pulse frequency of 80 kHz, otherwise incorrect counting may occur
(e.g. Motrona DX-345).
4.4.2 Burst output
By triggering a burst output, it is possible for the position measured as an absolute value by the
encoder to be output uniquely as an incremental pulse sequence with a frequency of 10 kHz.
The number of pulses corresponds to the angular distance to the zero point (single-turn) in the
set effective direction and resolution. The burst output is triggered via the Easy-Teach function
(see section “Setting“).
