CANx DALI questions

[Novodk]

We have a project where they have installed 80 DALI2 ballasts and 6 DALI2 B.E.G PD4N-BMS sensors.
First and foremost we hate these projects! Why not put up 6 KNX sensors instead!
Anyway, we previously used a KNX/DALI gateway that could control both ballasts and sensors.
If we buy 1x LM5p2-KCD, 2x CAN-DALI-M3, then we can control 30 DALI2 ballast/sensors from each device?
And we need a suitable DALI PSU as well?

We haven't tested BEG sensors but if they adhere to DALI2 standard they should work as any other.

For LM5p2-KCD you need an external DALI power supply like Mean well DLP-04R. For CAN-DALI-M3 you can use standard DC 15V..18V power supply like Mean well HDR-15-15.

Can someone confirm that CAN-DALI-M3 and LM5p2-KCDZ is limited to controlling 30 DALI-2 ballasts/control gear? We are used to our gateways can controll 64 devices per DALI line, so I just want to make sure I have the right information before I proceed with my project.

30 is a recommended limit if internal DALI power supply is used on CAN-DALI-M3. With an external DALI power supply you can use 64 ballasts.

Hi.

As a wish for further updates on the CANx DALI configuration:
- When assigning dali ballasts to groups, it would be a great help to have a "flash" button in the group assigning tab. With this it won't be needed to enter each ballast -> make them blink -> name them and THEN assign them to groups. Instead simply: Assign by flashing and assigning group directly.

I hope it makes sence

this?

Yes, exactly that !

I'm sorry. I hadn't updated the app, and now the flash (as in your pic) is there, and also the feedback value/switch on each group!
My bad !

don't forget to set short address and minimum level of feedback device in group settings to get correct status value in knx

[Novodk]

Is there a reason for this? Physical minimum = 85

Is there a reason for this? Physical minimum = 85

if you wil set here 100 in minimum level, but in group settings you will set 1 as minimum level, then you wil not get effect in range 1-40 % and 40% wil be minimum value in status

Further question:

If I use only LM5p2-KCD will it be able to handle 64 DALI devices with the 24 VDC supply (as usual)?

Thanks

[admin]

Yes, but you need an external DALI power supply (Mean Well DLP-04R or any other alternative).

[PolymorphedCust]

and where should this DALI PSU be connected? I'm thinking of getting the LM5p2-DW1

[admin]

KCD/KCDZ is a newer device with more features. If you need more DALI lines you can add CANx-DALI gateways to it.

Both KCD and DW1 require an external DALI power supply. Check LM connection diagrams page 6 (DALI): https://logicmachine.net/downloads

[PolymorphedCust]

OK thanks. But I need the LM5p2-DW1 'cus it has 1-wire as well

What features will I be missing?

[admin]

Old DALI implementation is very limited - you can only control each ballast separately using on/off and scale objects. Everything else must be done using scripts.

KCD supports DALI groups (control of multiple ballasts), scenes, CCT/RGB/RGBW ballasts. You can change most of ballast parameters directly from the UI. It also supports DALI2 sensors and push-button inputs.

Ok thanks for the info
