  • Page 9: General Information

    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).

  • Page 10: Device Description

    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.

  • Page 11: Measuring Principle

    In the case of a manual length measurement, the measured value must be confirmed by pressing a key so that it can be saved automatically. If the VLM500-MID is equipped with a data interface, this data record is automatically output to the data interface (not legally relevant). Furthermore, metadata (e.g. batch number, article number) can be transmitted to the CDB for protocol purposes.

    VLM500-MID User Manual Device description white light LED is used to illuminate the measurement object. Due to the broadband nature of the light, the greatest possible degree of surface independence is achieved. Any extraneous light that occurs is effectively suppressed by using a differential measurement method.

    Device description VLM500-MID User Manual 2.4 LED-Indicators The VLM500-MID has integrated LED to display operating states. The VLM500 has five LED in the lid, whereas the CDB has one LED in the membrane keyboard. Table 1: Indicators of the VLM500-MID...

  • Page 14: Software Integrity And Software Identification

    The software automatically carries out the integrity check every 60 minutes. If at least one of the checksum deviates from the reference value, the user is informed of this state with a message and the VLM500-MID is switched to the unsecured state.

  • Page 15: Preset Length Outputs

    VLM500-MID User Manual 2.6 Preset length outputs The VLM500-MID has two switching outputs for adjustable preset length. These switch when the currently measured length value is equal to or greater than a previously programmed target length. These nominal lengths (preset length) can be set via the user interface of the CDB. Both values are entered in meters. For more information how to adjust the values via the user interface refer chapter 5.7.

  • Page 16: Operating Modes

    That means intentional or unintentional parameter or other changes shall be impossible. Precautions have been taken for the VLM500-MID that meet these and other requirements. When a length measurement machine is calibrated, the VLM500-MID is in secure mode. The secure mode is represented by attaching seals and lead seals to both the VLM500 housing and the CDB housing (see the photo on the cover sheet of this user manual as an example).

  • Page 17: Device Models

    Device models VLM500-MID User Manual Device models Different device models of the VLM500 series are available, which are electrically- and connection-compatible. Most options (interface cards, assembly accessories etc.) can be used for all models. The differences in measurement range, working distance and distance variance result from the used optics and the signal processing of the devices VLM500A, VLM500D and VLM500L.

  • Page 18: Cdb Handling

    The CDB is supplied with power via the VLM500. The CDB is therefore switched on together with the VLM500. After switching on, the ASTECH logo is shown on the CDB display. This is followed by the display test, the integrity check of the software and the display of the software identification.

  • Page 19: Menu Structure

    CDB Handling VLM500-MID User Manual If this occurs, the device can still be operated and used. However, new measured values are saved as invalid measured values. The software identification (version numbers of the software) is displayed after the checksums. After this automatic switch-on test run, the menu measurement display is automatically displayed. A length measurement process can then be started right away.

    5.5.2 Storage period and memory size The storage capacity in the VLM500-MID offers space for a total of 3,938,104 data records. If a memory location is occupied, the next free memory location is used automatically. If all storage locations are occupied and the minimum period for storing the oldest data record has not been exceeded, no more datasets can be saved.

To share the data set with a PLC, PC, Server, the - button must be pressed on time. The meta data (e.g. article number/name, machine name) of a dataset can be showed by pressing the - button.

  • Page 24: Invalid Measured Values

    If a saved dataset was defined as invalid by the software, it is copied in the list of invalid measured values. There can be three reasons for an invalid dataset. First, the VLM500-MID was in unsecured mode while the dataset was saved.

    The device connections 1, 4 and 5 on the VLM500 are optional and are only equipped with a flange if an additional output interface (pulses, analog, process data) has been purchased with the VLM500-MID Device connections that are not connected are to be protected against the ingress of dirt by means of blind plugs.

  • Page 34: Power Supply And Grounding

    8.2 Power supply and grounding The VLM500-MID operates with a 24 V DC power supply (20 to 30 V). The supply takes place via device connection 3 on the VLM500. The CDB is power supplied from the VLM500 via the VLM500/CDB connection cable.

  • Page 35: Service Interface Usb

    Windows must be fully started for the driver to be installed. The "IUSB_driver_FTDI.zip" file must be extracted to a known location on a hard drive. Then the VLM500-MID is connected to the PC. It is advisable to first connect the end of the cable to the CDB and then the other end of the cable to the PC. Windows should now have recognized the new hardware and search for a driver.

  • Page 36: Printer Connection

    VLM500-MID User Manual Connections and Interfaces Note: The VLM500-MID does not have to be switched on to install the driver. The FT230X is supplied with power by the PC and thus enables the driver to be installed. If the VLMTool is installed, the user is automatically offered to install the USB driver as well. For this it is recommended not to connect the VLM to the PC.

    Maintenance 9.1 General The VLM500-MID works optically. It is dependent on seeing the measurement object. Thus, it is necessary to check the VLM500 window in regular intervals and clean it, if necessary. The cleaning should be made with a soft, lint-free cloth and customary glass cleaner.

  • Page 48: Led Lamp

    Secured mode If the VLM500-MID is in the secured operating mode, the housing of the VLM500 is sealed. A change of the light source is only possible if the seal is removed. Changing the light source has no effect on the measuring behavior of the VLM500-MID.
