The radiation emitted from a class 1 laser is harmless. This type of laser instrument can
be operated by anyone.
The company operating the device is responsible for planning, assembly, commission-
ing, operation, and maintenance.
Installation and commissioning of all devices must only be performed by personnel spe-
cially trained for that purpose.
The protection of the operating personnel and the overall system is not ensured if the as-
sembly is not used according to its intended purpose.

vicesareonlyapprovedforproperuseinaccordancewiththeirintendedpurpose.Failure
to comply with these provisions will invalidate all warranties and absolve the manufactur-
er of all liability.
Use only recommended original accessories.
If malfunctions cannot be eliminated, take the device out of service and secure it from
accidental use. Secure the device against inadvertent operation. For repairs to the de-
vice, send the device to Pepperl+Fuchs. Only Pepperl+Fuchs can make repairs to the

4 Product description
VDM54
The VDM54 is the reliable solution for measuring the distance between vehicles on rail
mounted tracks. Braking distances and distances between vehicles differ according to
the type of goods being carried, the length of the vehicle, and the speed of the vehicle.
This requires adjustable switching distances. Constantly changing objects around vehi-
cles and the presence of other sensors do not impair the VDM54's ability to accurately
measure distances. In order to maintain the reliability of the distance measuring function
and ensure accurate switching points, regardless of the surroundings and conditions of
the vehicles themselves, a reflector is fitted to the rear of every vehicle in the installation.
The VDM54 is fitted to the front of each vehicle and always points at the reflector on the
vehicledirectlyahead.Whenthevehiclereaches the currently selectedbrakingdistance,
the switching output is activated and the vehicle slows down. When the vehicle reaches
theselectedstoppingdistance, it comes to a complete standstill. Once the vehicle in front
begins to move, the signals are enabled and the vehicle travels forward. When using ve-
hicles of variable length, e.g. due to overhanging loads, the distances maintained in the
installation can be varied. This VDM54 function enables optimum use of congested ar-
eas.
Measurement principle
The VDM54 works on the principle of optical time of flight measurement. Distance mea-
surement uses the physical principle that light always spreads at a constant speed of
c=299,792 kilometers per second. In other words, light travels a distance of 1 m in 3.335
ns (0.000,000,003,35 s). With pulsed time of flight measurement, a very short light im-
pulse is emitted, reflected, and registered by the receiver; the measured time is stopped
at that very same moment. The emitted impulse triggers a clock which is stopped by the
received impulse. The time elapsed (time of flight) is always proportional to the optical
path length.
Use of this physical principle makes VDM54 ideal for optical anti-collision distance mea-
surement.

4.1 Models
4.1.1 VDM54-6000-R/20/105
• Detection range: 0 – 6 m
• Aperture angle: horizontal ± 7.5 degrees; vertical ± 3.5 degrees
• 2 PNP NC outputs Q1, Q2
• 1 range selection input
The four signal points (close / far for both Q1 and Q2) are programmed via a ConfigBox.
The ConfigBox has a serial RS-232 interface and connects to the VDM54 with a pro-
gramming cable.
Distancevaluesforswitchpointscanbe programmed usingparametersoftware currently
available free of charge.
Advantages: It is very simple to install in existing installations. Sensor settings are easy
to reproduce and can be recorded. Sensors can be easily preset outside the installation
(short commissioning time).
4.1.2 VDM54-6000-R/20/88/105 and VDM54-6000-R-3999
• Detection range: 0 – 6 m
• Aperture angle: horizontal ± 7.5 degrees; vertical ± 3.5 degrees
• Serial interface RS-485
The VDM54-6000-R/20/88/105 only communicates with the vehicle control system via
the RS-485 interface. The control system software must have implemented the protocol
for the VDM54-6000-R/20/88/105.
Advantages: Parameter settings are carried out via the control system. Should it be nec-
essary to replace one VDM54 with another, no sensor adjustments are necessary.

5Installation
5.1 Storage and transportation
When packing the device for storage or transportation, use materials that will protect the
device from jarring, impacts and humidity. The original packaging provides the best pro-
tection. Take into account the permitted ambient conditions as well.
5.2 Unpacking
Check that the contents are not damaged. In case of damage, inform the postal service
or delivery agent and notify the supplier.
Check the scope of delivery against your order and the delivery documents.
Keep the original packaging in case the device must be stored or shipped at a later date.
If you have any questions, please contact Pepperl+Fuchs.
5.3 Installation
5.3.1 Installation/Mounting example
The illustration shows how the frame protects the VDM54 and reflector from damage
when the vehicles are pushed together for servicing.
If the device has been subjected to extreme temperature fluctuations
during transportation, it must be allowed to acclimatize for approxi-
mately one hour before being installed and put into operation. Always
prevent condensation from forming in or on the unit as this could result
in internal components being damaged.
Do not point the sensor directly at the sun. Always protect the sensor
against direct and lengthy exposure to sunlight. Prevent the formation
of condensation by not exposing the sensor to large fluctuations in tem-
perature. Keep the sensor away from aggressive chemicals. Make sure
that the glass and the reflector on the device are kept clean. Always use
soft cloths and, if necessary, a commercial glass cleaner.

6 Commissioning
After the device is turned on, the VDM54 is ready for operation after completing an ini-
tialization phase of approx. 10 seconds.
To achieve maximum accuracy, allow the device to warm up for 10 minutes.
The sensor has been tested and calibrated before leaving the factory. It can be placed in
operation immediately.

7.1 Software installation
Switch points can be programmed from a PC. VDMConfig parameter software must be
successfully installed on the appropriate device and a Pepperl+Fuchs ConfigBox is re-
quired. The ConfigBox is connected to the PC via RS-232 interface.
When the setup.exe file is started, the following window appears:
Follow the instructions on the screen until installation of VDMConfig is complete. Once
VDMConfig has been successfully installed, the program can be started e.g. via the Win-
dows Start button.
7.2 Programming with VDMConfig
In order to program settings on the VDM54 ensure that:
1. the VDM54 is connected to the power supply,
2. the VDM54 is connected to a free COM interface on the PC via the VDMConfig Box.
3. VDMConfig is installed on the PC.
When is started, the VDMConfig start window appears:
