DALI Troubleshooting with DALI check list


1.Troubleshooting: DALI check list

   If you are having problems with (the first things to check if you are having problems)

  Check number of addresses: 63 or fewer

  Check total current consumption of all the devices connected is not more than 250 mA.

  Check cable length: total cable length should not be more than 300m.

  Check DALI signal voltage

    Use a suitable multi-meter check the DALI signal voltage.

    Ideally the measured voltage should be between 16 V DC and 22.5 V DC with no more than a 2 V DC drop along the cable length. If you read less  than 14 V DC, it is likely that you have, or will have, a problem with your DALI system.

2. What to do if there is no response to DALI broadcast from system

  If your system / connected loads do not respond correctly to your DALI broadcast command you can start to diagnose the problem from the observations you make.

  Below you will find some tips to get you started. (these are not 100% guaranteed solutions, they are meant as helpful hints)

  A. None of my loads responds

     Check the DALI signal by measuring between 16V DC and 22.5V DC on the DALI cable 

    If lights are off check mains power is connected to the loads2.

B. Only some of my loads respond

   Check mains power is connected to the loads that are off

   Check the DALI signal with your multi-meter at the terminals of the loads that are not working

   Check the lamp(s)

C.Only one load does not respond, everything else is OK

   Check mains power is connected to the load that is off

   Check the DALI signal with your multi-meter at the terminal of the load that does not respond

  Check the lamp(s)
