1 General information
1.1 Explanation of symbols
The symbols used in this technical description are explained below.
1.2 Important terms
Phase measurement
Distance measurement 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 phase position of the signals received by the ODSL 30 lim-
its 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 see chapter 3.8.2).
Absolute measurement accuracy
Shows the possible divergence of the measurement value from the anticipated value through
changes in the environmental conditions during the measurement process. Higher accuracy is given
at constant environmental conditions
Repeatability
Measurement distance change with repeated measurement at the same output signal (observe the
same boundary conditions as with resolution).
Resolution
The smallest possible change in distance of the measurement object, which causes a unique change
of the output signal.
Referencing
Device function of the ODSL 30… for the compensation of a possible temperature drift. A referencing
should be carried out before each exact measurement. The referencing 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 depends on the selected uniqueness range and the object diffuse reflec-
tance (see see chapter 3.8.2).
Readiness delay
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 behavior of the switching output: light switching if an object is located within the config-
ured distance range, dark switching if an object is located outside of the configured distance range.
Attention
This symbol precedes text messages which must strictly be observed. Failure to
observe the provided instructions could lead to personal injury or damage to
equipment.
Attention, laser radiation
This symbol warns of possible danger caused by hazardous laser radiation.
Note
This symbol indicates text passages containing important information.

Leuze electronic GmbH + Co. KG ODSL 30 5
Ambient light sensitivity
Indicates the insensitivity of the measurement result towards ambient light. The ODSL 30 measures
reliably even with ambient light intensity of 5kLux. Typical light intensity in a work place is only
1kLux.

Description ODSL 30
Leuze electronic GmbH + Co. KG ODSL 30 10
3 Description ODSL 30
3.1 General description
The ODSL 30 is a laser distance sensor with an extensive range of applications. The devices are available
in different versions with analog outputs, digital outputs, or switching outputs. The distance measurement
uses the phase measurement principle. The measurement range1) lies between 0.2…30m. The device
models with serial output allow a measurement range up to 65 m.
Integrated in the device are a membrane keyboard and a two-line LC display which can be used to
configure the ODSL 30. During measurement operation, the display shows the current measurement
value. The switching point of the switching outputs can easily be set via a teach input on all variants.
By carrying out the integrated referencing function before a measurement, the sensor's accuracy can be
improved. To achieve this, the active input (PIN 2) can be configured via the menu to act either as an ac-
tivation input with referencing, or as a pure referencing 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 potential equalization.
Accessories
The mounting device BT 30 is already included in the scope of delivery of the ODSL 30 for easy mounting
and alignment (for further accessories, see see chapter 5.2).
1) Diffuse reflectance 6 … 90% throughout the entire temperature range, measurement object ≥ 50 x 50mm2.
ODSL 30/D…: Measurement range up to 65m, diffuse reflectance 50 …90%
NOTE
Moving objects into the measurement beam from the side may lead to incorrect measurement
values.

3.2 Typical areas of application for the ODSL 30
3.2.1 Continuous distance measurement
All ODSL 30 variants with analog, digital or switching outputs are ideally suited for continuous distance
measurement. The menu-guided configuration via membrane keyboard and LC display on the device
without additional software permits the adaptation to a large number of applications.
Depending on arrangement and 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 with simultaneous movement of the
object.
• Diameter determination, 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 analog output and/or up to three teachable switching outputs are ideally suited
for basic positioning tasks, such as the height/level adjustment of lifting tables and lifting platforms.
The ODSL 30 is mounted in a way to enable positioning in the direction of the measurement beam.
Figure 3.1: Positioning of lifting tables application example
3.2.3 Collision protection
The ODSL 30 is ideally suited to be used as collision protection device:
• Distance regulation via the analog output of the ODSL 30
• Collision prevention via the switching outputs of the ODSL 30

Behavior of the analog outputs of the ODSL 30/V…
The ODSL 30/V… has an analog output with linear behavior. 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 analog output should be set as small as the application allows. The analog output can be adjusted
within the measurement range by configuration via the membrane keyboard and LC 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 configured as
rising or falling. For this purpose, the two distance values Pos for min. val and Pos for max. val
for the minimum and maximum analog output value are set accordingly in the range between 200mm and
30,000mm (see Figure 3.4 and Figure 3.5).

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 char-
acteristic output curve is also possible via a teach line for devices with software version V01.10 and newer
(see see chapter 3.6.5). The following steps are required for the line teach-in of the analog characteristic
curve:
1. Activation of the analog line teach function via the membrane keyboard and menu.
Activate Input Menu -> Teach Mode -> Teach Mode time control.
2. Position measurement object at the desired measurement 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 signaled 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.
Behavior 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 analog 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 behavior (light/dark switching), and the type of switching output (PNP high active or NPN low
active or PNP/NPN push-pull).

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 implemented 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 3.7):
•ASCII measurement value (6 bytes, measurement range 0 … 65m, resolution 1mm) 1)
•ASCII measurement value 0.1mm (7 bytes, measurement range 0 … 65m, resolution 0.1mm) 1)
•14 bit measurement value (2 bytes, measurement range 0 … 16m, resolution 1mm) 1)
•16 bit measurement value (3 bytes, measurement range 0 … 65m, resolution 1mm) 1)
•20 bit measurement value (4 bytes, measurement range 0 … 65m, resolution 0.1mm) 1)
•Remote control operation 2)
The output format is activated by configuration with the membrane keyboard and menu.
1) Continuous measurement value output in a 100ms grid. For the ODSL 30/D 485…, the data transmission 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 data transmission 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.
NOTE
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 application.
