1General information
1.1 Information on how to work with this manual
Commands and functions are displayed in italics. The use of upper case and lower-case letters serves for
improving the readability:
e.g. SO2On (Command for switching on the output at the serial interface S2).
The abbreviated form recommended for the input is additionally displayed in bold letters in the syntax:
e.g. SO1Format (Command for programming the serial interface 1).
The following signs are used:
n Integral number s String
f Floating point number [ ] Optional
c Sign
The following acronyms are used for the measurement parameters:
V Velocity N Object counter
L Length R Measuring rate
1.2 Safety instructions
These safety and operating instructions should be carefully read and followed during practical work with the
device. Compliance with all specified operating conditions is necessary. Failure to observe advisory notes or
nonconforming product usage may cause material damage to the VLM500-MID or lead to wrong measurement
results. Cable connectors must not be plugged or unplugged under voltage. Remember to turn voltage supply off
before you begin working on cable connections.
A light emitting diode (LED) is used as the light source for the VLM500. The LED classification is subject to the
potential photobiological hazard according EN/IEC 62471 named “Photobiological safety of lamps and lamp
systems”. They are not classified according EN 60825 “Safety of laser products”. The lamp of the VLM500 is
classified to the risk group RG-2 (moderate risk) according to the manufacturer. That means that the lamp
represents no hazard due to the natural reaction to look away from bright light sources. The following advice
should be considered anyhow.
Do not stare at operating lamp. It may be harmful to the eye.
Machine directive 2006/42/EC
In the sense of the EU directive “2006/42/EC” the VLM500-MID is not a machine. Hence there is no conformity
declaration available for the device. The directive 2006/42/EC regularizes the requirements on machines. Here,
a machine is meant to be the entity of connected parts or mechanisms (see also EN 292-1, section 3.1). The
VLM500-MID is part of the electrical and sensor equipment of a machine. The machine manufacturer must
consider the VLM500-MID in its process for the declaration of conformity.

2Device description
2.1 Intended use
The measuring device for velocity and length VLM500-MID (the known VLM500 connected with a device to store
and display the measured length values, CDB) is suited for measurements on different materials. The scope of
applications of the VLM in process automation is an extremely wide one. Typical applications are length
measurement of web-type materials and the cutting control or post-control of sheets, profiles and tubes.
The VLM500-MID is designed for the integration into a length measuring machine (LMM). Dependent on the
intended use of the LMM, a calibration of the machine according to the local authorities, can be necessary. In
this sense the VLM500-MID is treated as counter. The counter was pre-tested by the national certification body
„Physikalisch Technische Bundesanstalt (PTB)“ located in the city of Braunschweig, Germany. With the purchase
of the VLM500-MID the customer receives the confirmation, that the device corresponds to the requirements of
the software guide WELMEC 7.2. This guide provides technical guidance for the application of the Measuring
Instruments Directive (MID 2014/32/EU), for software-equipped measuring instruments.
1
This simplifies the
integration and the calibration process for plant manufacturers.
2.2 Two components –one device
General
The VLM500-MID consists of the two main components VLM500 and CDB. The VLM500 is the sensor. The CDB is
a display and storage unit. The length values recorded by the VLM500 are displayed on the CDB screen. When a
length measurement has been completed, the length value is saved together with status information as a data
record in the CDB. If necessary, the data record can also be output via a digital interface. The user can navigate
through a user interface using four buttons located below the display, call up saved measured values and print
them out if necessary. In unsecured mode, the VLM500-MID is parameterized via a serial communication
interface. Both units are connected with a cable.
2
The CDB is supplied with power from the VLM500 via this
connection. Furthermore, the data exchange between themodules takes place via the cable. The housing of both
units is IP 65 rated. The power supply is done with 24 VDC.
Figure 1: The VLM500-MID as a part of a length measuring machine

The VLM500-MID fulfills the accuracy class III according to the measuring instrument directive.

The customer can select between 5m and 10m cable length.
