The LVB control unit has the following features:
One transmitter/receiver set can be
•
connected.
Relative switching threshold for reliable object
•
recognition.
Increased safety: safe shut down on contact
•
bonding and no blanking of defect beams.
Floating relay contacts.

General description

General description
General description
General description
The device switches when one or more beams are
interrupted.
The output relays have positively driven contacts
(2xreverser), each with one break contact lead back to
a digital input. That ensures the detection of a failure
(„contact did not open") of the brought out normally
open contact. A watchdog unit cuts off the relays at a
failure of the microcontroller.

  • Page 4: Self Calibration

    Technical Information Self calibration Self calibration Self calibration Self calibration On self calibration the controller set up the correct gain for the connected light grid set, determines the profile length and executes an error test. During self calibration the monitoring area has to be uninterrupted (Exception: see automatic blanking). Procedure: Procedure: Procedure:...

  • Page 5: Leds

    LEDs LEDs The LVB indicates operational errors and faults via the eight adjacent LEDs RX, TX, A… F. If the status is normal, LEDs C, D, E, F indicate the signal strength. Please note that the error cannot be localized with 100 percent accuracy. The LEDs only provide you with a good idea of where to start looking.

  • Page 10: Important Notes Concerning Usage And Handling

    Technical Information • Danger from reflective surfaces: Reflective surfaces in the area around the light curtain must be avoided. Otherwise obstructions will not be detected. • Avoid optical sensors from mutually affecting each other (e.g., other light curtains, light barriers) Important notes concerning usage and handling Important notes concerning usage and handling Important notes concerning usage and handling...
