1 General Information
1.1 Explanation of symbols
The symbols used in this technical description are explained below.
Attention
Pay attention to passages marked with this symbol. Failure to heed this information may
lead to injuries to personnel or damage to the equipment.
Attention Laser Radiation
This symbol warns of possible danger through hazardous laser radiation.
Notice
This symbol indicates text passages containing important information.
1.2 Important Terms
Phase measurement
Distance measuring procedure, which determines the distance of an object by the
shift of the phase angle of the light reflected from the object.
Uniqueness range
Due to the periodicity of the sinusoid, the phasing of the signals received by the
ODSL 30 limits the determination of unique measurement values to within a specific
interval. The length of this interval is called the uniqueness range. A large uniqueness
range is equivalent to high background suppression (see chapter 3.7.2).
Absolute measurement accuracy
Shows the possible divergence of the measurement value from the anticipated value
through changes in the environmental conditions during the measuring process.
Higher accuracy is given at constant environmental conditions.
Repeatability
Measuring distance change with repeated measurement at the same output signal
(observe the same peripheral conditions as with resolution).
Resolution
The smallest possible distance change of the measured object, which causes a defi-
nite change in the output signal.

Leuze electronic General Information
Leuze electronic ODSL 30 5
TNT 35/7-24V
Reference measurement
Device function of the ODSL 30… for the compensation of a possible temperature
drift. A reference measurement should be carried out before each exact measure-
ment. The reference measurement is activated via a separate device input and is
automatically carried out once after the device is switched on.
Diffuse reflection
Return and/or degree of reflection of the radiated light.
Measurement time
The measurement time is dependent on the selected uniqueness range and the lumi-
nosity coefficient of the object (see chapter 3.7.2).
Delay before start-up
The delay before start-up indicates the point in time when the first valid measurement
can be obtained after switching on.
Light switching/Dark switching
Specifies the behaviour of the switching output: light switching if an object is located
within the configured distance range, dark switching if an object is located outside of
the configured distance range.
Insensitivity towards extraneous light
Indicates the insensitivity of the measurement result towards extraneous light. The
ODSL 30 is reliably measuring even with extraneous light intensity of 5kLux. Typical
light intensity in a work place is only 1kLux.
1.3 Declaration of Conformity
The optical distance sensors of the ODSL 30 series have been manufactured observing
current European standards and guidelines.
Notice
The corresponding declaration of conformity can be requested from the manufacturer.
The manufacturer of the product, Leuze electronic GmbH + Co KG in D-73277 Owen/Teck,
possesses a certified quality assurance system in accordance with ISO 9001.

2.3 Working Safely
Attention Laser Radiation!
The optical distance sensors ODSL 30 operate with a red light laser of class 2 acc. to
EN 60825-1.If you look into the beam path over a longer time period, the retina of your
eye may be damaged!
Never look directly into the beam path!
Do not point the laser beam of the ODSL 30 at persons!
When mounting and aligning the ODSL 30, take care to avoid reflections of the laser
beam off reflective surfaces!
The use of operating and adjusting devices other than those specified in this techni-
cal description, carrying out of differing procedures, or improper use of the optical
laser distance sensor may lead to dangerous exposure to radiation!
The use of optical instruments or devices in combination with the device increases
the danger of eye damage!
Adhere to the applicable legal and local regulations regarding protection from laser
beams acc. to EN 60825-1 in its latest version.
The ODSL 30 uses a laser diode with low power in the visible red light range with an
emitted wavelength of about 655nm.
The glass optics cover is the only opening through which the laser radiation can es-
cape from the device. The housing of the ODSL 30 is sealed and has no parts that
need to be adjusted or maintained by the user. The device must not be tampered with
and must not be changed in any way! The destruction of the seal voids the warranty!

Safety Notices Leuze electronic
8ODSL 30 Leuze electronic
Notice!
It is important that you attach the sticky labels supplied to the device (notice signs and laser
emission symbol)! If the signs would be covered due to the installation situation of the
ODSL 30, attach them close to the ODSL 30 such that reading the notices must not lead to
looking into the laser beam!

3 Description ODSL 30
3.1 General description
The ODSL 30 is a laser distance measuring device with a large area of application. The
equipment is available in different versions with analogue outputs, digital outputs, or
switching outputs. The distance measurement uses the phase measurement principle. The
measurement range lies between 0.2 … 30m.
Integrated in the device are a keypad and a two-line LCD display which can be used to
program the ODSL 30. During measurement operation, the display shows the current meas-
urement value. The switching point of the switching outputs can easily be set via a teach
input on all variants.
Remarks
Moving objects into the measurement beam from the side may lead to incorrect measure-
ment values.
By carrying out the integrated reference measurement function before a measurement, the
sensor's accuracy can be improved. To achieve this, the active input (Pin 2) can be config-
ured via the menu to act either as an activation input with referencing, or as a pure referenc-
ing input. While the referencing function is carried out (duration about 0.3s), no
measurement can be taken.
If the device is used in areas subject to electrostatic charges, it is recommended to connect
the housing of the ODSL 30 to a common potential.
Accessories
The ODSL 30 ships with the mounting device BT 30 for easy mounting and alignment
(further accessories see chapter 4.5).

3.2 Typical Areas of Application for the ODSL 30
3.2.1 Continuous Distance Measurement
All ODSL 30 variants with analogue/digital or switching output can be used for continuous
distance measuring. The menu-guided configuration via key pad and LC display on the
device without additional software permits the adaptation to a large number of applications.
Depending on position or settings of the ODSL 30, various applications are possible:
• Positioning of side-tracking skates, cranes, lifting devices
• Contour determination through controlled passing movement of an object through the
beam of the ODSL 30.
• Volume measuring by taking measurements on two levels during the concurrent
movement of the object.
• Determination of the diameter, e.g., on paper rolls.
• Measuring the thickness of planks with two opposing sensors and a differential of the
two measured values.
3.2.2 Positioning Tasks
The ODSL 30 variants with analogue output and/or up to three teachable switching outputs
are ideally suited for basic positioning tasks, such as the height/level adjustment of elevating
platforms and rising floors.
The ODSL 30 is mounted in a way to enable positioning in the direction of the measuring
beam.

Behaviour of the analogue outputs of the ODSL 30/V…
The ODSL 30/V… has an analogue output with linear behaviour. A current output
(4 … 20mA) and a voltage output (1 … 10V) are available to the user. In order to achieve
the highest resolution possible, the range of the analogue output should be set as small as
the application allows. The analogue output can be adjusted within the measurement range
by configuration via the key pad and LCD display (adaptation of the characteristic output
curve). The parameter Cal. Ana. Output determines whether the calibration is to be
carried out for the current or voltage output. The characteristic output curve can be config-
ured with a positive or negative gradient. For this purpose, the two distance values
Pos for min. val and Pos for max. val for the minimum and maximum
analogue output value are set accordingly in the range between 200mm and 30,000mm
(see figure 3.5 and figure 3.6).
Teach-in of the characteristic output curve
In addition to the edge-controlled teach-in (slope control) of the switching outputs, teach-
in of the characteristic output curve is also possible via a teach line for devices with software
version V01.10 and newer (see chapter 3.5.5). The following steps are required for the line
teach-in of the analogue characteristic curve:
1. Activation of the analogue line teach function via the key pad and menu.
Activate Input Menu -> Teach Mode -> Teach Mode time control.
2. Position the measured object at the desired distance.
3. The respective teach function is activated by applying the active level (default +UB) to
the teach input "Teach Q1" (pin 5). The teach event is indicated by the flashing of the
LEDs and on the display.

4. To finish the teach event, disconnect the teach input from the teach signal after the
desired time.
5. A successful teach event is signalled by the end of the flashing of the LEDs. The
menu entries can be used to check that the teach values are properly accepted and to
make any changes.
Error messages
Rapid flashing of the green LED following a teach event indicates an unsuccessful teach
event. The sensor remains ready for operation and continues to function with the old values.
Remedy:
• Repeat teach event or
• Activate teach input for more than 8s or
• Disconnect sensor from voltage to restore the old values.
Behaviour of the switching output of the ODSL 30/V…
Additionally, a switching output with two switching points (switching window) is available with
the ODSL 30/V… with analogue output. The upper switching point can be taught using a
teach line. By configuring within the measurement range, it is possible to set the lower and
upper switching points, the switching hysteresis, the switching behaviour (light/dark
switching), and the type of switching output (PNP high active or NPN low active or PNP/NPN
push-pull).
Teaching always takes place towards the upper switching point (see figure 3.7 on page 17).
The lower switching point is set to 199mm by default.

The ODSL 30/24… is equipped with three independent switching outputs, each with 2
switching points (switching windows). The upper switching points can be taught using a
teach line. By configuring within the measurement range, it is possible to set the lower and
upper switching points, the switching hysteresis, the switching behaviour (light/dark

3.4.3 ODSL 30/D… with Serial Output
Transmission formats
The ODSL 30/D… has 2 digital switching outputs and one serial interface which is imple-
mented either as an RS 232 interface or as an RS 485/RS 422 interface. The transmission
rate can be set to between 600 and 115200 baud.
The serial transmission is carried out with 1 start bit, 8 data bits and 1 or 2 stop bits without
parity.
For the transmission of the measurement values, 6 different transmission modes may be
configured (see figure 3.8):
•ASCII measurement value
(7 bytes, measurement range 0 … 30m, resolution 1mm)1)
•ASCII measurement value 0.1mm
(7 bytes, measurement range 0 … 30m, resolution 0.1mm) 1)
•14 bit measurement value
(2 bytes, measurement range 0 … 15m, resolution 1mm) 1)
•16 bit measurement value
(3 bytes, measurement range 0 … 30m, resolution 1mm) 1)
•20 bit measurement value
(4 bytes, measurement range 0 … 30m, resolution 0.1mm) 1)
•Remote Control Operation
(Remote Control) 2)
The output format is activated by configuration with the key pad and menu.
Notice!
Selecting an output resolution of 0.1mm does not change the internal measurement system
of the ODSL 30 and does not increase its accuracy. For this reason, measurement values
with a resolution of 0.1mm may vary in successive measurements depending on the appli-
cation.
1) Continuous measured value output in a 100ms grid. For the ODSL 30/D 485…, the transfer is
carried out in RS 422 mode, i.e., with permanent transmission on the Tx+ and Tx- lines.
2) For the ODSL 30/D 485…, the transfer is carried out in RS 485 mode, i.e., the Tx+ and Tx-
lines are switched to receive. This permits several ODSL 30/D 485… to be connected onto a
single bus. In this case, the device addresses of the individual devices must differ from each
other.
The ODSL 30/D 232… can also be operated via remote control, however, only as a point-to-
point-connection between the ODSL 30 and the controller.
