Why is bus operation not possible with my Leuze electronic DDLS 200 Microphone system?

  Bus operation might fail due to several reasons. It could be a transmission error (refer to the troubleshooting section on 'transmission error'), a wiring error (check the wiring), an adjustment error related to termination, baud rate, or configuration (verify settings), an incorrect bus cable (use the specified bus cable), or a deactivated transmitter/receiver unit (ensure correct wiring and S1 position; set to 'Adjust' operating mode, ensuring the ADJ LED is not flashing).

What to do if ADJ LED flashes on Leuze electronic DDLS 200?

  Melissa BeckerAug 16, 2025
  The ADJ LED might be flashing because of a light beam interruption or no visual connection to the opposing device when it is in 'Manual' operating mode. Check the light path. Another reason could be misalignment of a DDLS 200 when the opposing device is in 'Manual' operating mode; realign the transmission path.

Why PWR or UL LED flashes in Leuze electronic DDLS 200?
- M
  Michele NguyenAug 22, 2025
  The PWR or UL LED flashing indicates that the transmitter/receiver unit is switched off via input IN. Check input IN and the position of switch S1. Alternatively, it could indicate a hardware defect, in which case replace the device and send it in for repair.

How to fix PWR or UL LED when it does not illuminate on Leuze electronic DDLS 200 Microphone system?

  If the PWR or UL LED does not illuminate, the possible cause is that there is no supply voltage. Check the connections and supply voltage at the device and switch it back on. Another possible cause is a hardware defect. In this case, replace the device and send it in for repair.

  If you are experiencing a transmission error, consider the following potential causes and solutions: * Incorrect bus termination: Disconnect/connect terminating resistors. * Shielding not connected: Connect shielding correctly. * Receiving level too low due to misalignment: Realign, checking in 'Adjust' operating mode. * Receiving level too low due to soiling: Clean the optical window. * Receiving level too low due to operation with excessively large operating ranges: Observe operating limits. * Earth lead not connected: Connect the earth lead. * Influenced by parallel data path: Operate data transmission units with alternating frequency assignments, and check parallel distances. * Influenced by cascading data paths: Operate data transmission units with alternating frequen...
