– Green LEDs light continuously: CAN bus status "OK".
– Red LEDs light continuously: CAN bus status faulty.
Display of the status change on the multi-LED of the Processing Unit:
– Continuous green light: All units attached to the CAN bus have the "OK" status.
– Continuous orange light: At least one unit attached to the CAN bus has the "warning" status.
– Continuous red light: At least one unit attached to the CAN bus has the "alarm" status.
Display of the status change on the multi-LED of the access sensor:
– Continuous blue flashing: Communication over the CAN bus.
– Green flashing: When the measured value changes or, at the latest, every 5 seconds.
– Continuous red flashing: The access sensor has the "open" status.
– Continuous red light: Invalid measured value.
If the installation is not successful: see section 1.1.
Note:
