3.2 General safety instructions
The following basic instructions must be observed at all times:
• The device must not be placed into service until the manual has been read and under-
stood
• The power supply for generating the supply voltage must be insulated by a
double insulation and a safety transformer according to DIN VDE 0551 (complies with
IEC 742).
• The device must not be used outside the specifications without taking suitable protec-
tive measures
• No unauthorized tampering with the device is permitted
• Do not point the device directly towards the sun or take measurements in direct sun-
light
• Do not remove the warning/machine labels
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.
Observe the laws and/or directives applicable to the use or planned application. The de-
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
device. Interventions in and modifications to the device are not permissible, render the
warranty null and void, and exclude the manufacturer from any liability.
Dispose of the device according to all applicable laws and regulations.
For example, you can take the sensor to the designated collection center for electronic
scrap.
In applications with shelf stacking equipment and moving carriages,
care must always be taken to observe the applicable safety regulations.
Failure to observe this warning can result in fatal injury!

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.
