1 Signs and Symbols
2 Safety information
Warning
This symbol signals passages in the manual which must be observed at all times. Non-compliance can
cause injuries or material damage.
Warning Laser
This symbol appears in front of warning passages concerning the danger of laser beams.
Information
This symbol signals passages with useful information.
It is essential that this manual is read, thoroughly understood and observed before setting the
VDM18 sensor into operation.
The VDM18 sensor may only be connected, mounted and adjusted by qualified personnel.
Interventions and alterations to the device are not permissible!
The VDM18 sensor is not a safety component as described by EU machine directives.
The VDM18 sensor complies with laser protection class 2 according to DIN EN 60825/1, status
2001. The technical requirements comply with EN 60947-5-2, 2000 edition.
Never look into the path of the laser. Do not suppress the reflex to close the eyelids.
Gazing into the beam path for longer periods can damage the retina of the eye.
When mounting the sensor, ensure if possible that the beam path is sealed off at the end.
The laser must not be directed at people (head height).
When aligning VDM18, ensure that there are no reflections on reflective surfaces.
Should the safety label on the VDM18 sensor be partly covered due to its installation position,
other safety labels are to be positioned on visible parts of the sensor. When applying the new
safety label, make sure that you cannot look into the laser beam whilst reading it.

3 Appropriate use
The VDM18 sensor is not authorised for use in protecting human safety on machines and during
technical applications.
The VDM18 is an optical sensor and measures distances without contact. (triangulationsprinciple)

Sensor alignment
Position VDM18 so that the distance from the object is within the operating range of the sensor. Screw the VDM18
sensor to the mounting bracket, e.g. type OMH-VDM18 (not included in delivery) or a suitable device. Only use the
holes provided in the housing (see dimensioned drawing) for this purpose.
If steps, moving or striped objects are to be detected, the front panel of the sensor should be mounted at a right
angle to the direction of movement or stripes (Illustr. 2 + 3).
With very reflective objects, the sensor must be mounted at an angle of approx. 5° (Illustr. 4).
To optimise measurements, the VDM18 sensor is to be given constructive protection from vibra-
tions.
The VDM18 sensor is now mounted.

5 Electrical installation
Turn the sensor connector plug according to the installation position (Illustr. 1) so that the connection cable can be
freely connected without being bent.
Insert the socket of the connection cable into the VDM18 connector and screw tight.
For example, secure the connection cable from sliding with a cable tie.
Connect VDM18 as shown in figure 5.

Button lock
Free running
when HIGH (+UB)
when LOW (-UB)

* Laser-Disable:
A measurement is only made if the input is connected to –UB (buttons are locked) or is open.
The laser is switched off when +UB is applied to the input. The switching output and the analogue output retain their
last status.
Switch on the operating voltage (note the permissible operating voltage).
The sensor is ready to operate after a delay (≤300 ms). LED BA (green) must light.
For maximum precision, please allow for a heating period (approx. 5 minutes).

6 Operation and Setting
6.1 Possible Settings and Operating Modes
The VDM18 is ready to operate after applying the operating voltage.
However, the following settings can be made if necessary:
· Set the switching point or switching window
· Scale the analogue output
· Set the operating mode (Speed Mode / Averaging Mode )
· Set the switching type (light/dark)
· Reset the sensor to the factory state
· Laser off and measured value hold (via electrical connection)
· Lock buttons „S“ and „T“ (via electrical connection)
6.2 Factory State:
· Switching output:
Switching output is active when the object is in the operating range and reliably detected.
Switching type = light on
· Analogue output (4...20 mA): 4 mA = end of operating range, 20 mA = beginning of operating range
· Operating mode = speed mode (shortest response time)
· Operation = free running (normal mode)
6.3 Indicators and Setting Elements
The VDM18 is set with the buttons S and T.

Exit the Set menu (
T
+
S
) or
go to the next setting with the
