CBUS & Comfort Issue

Hi I have an issue, today I installed a CBUS USB Interface and also a comfort CBUS UCM, for some reason my CBUS network switched off, the unit light is on but the CBUS light is off.

If I unplug any unit from the Network, I.E one of the shutter relays then the network works, it dosn't matter which one, as soon as I plug them all in the CBUS light goes off and I can't use the network.

I have ruled out loose wires by using different leads and disconnecting different units. Could it possibly be not enough power? or could something else be causing this?

I have used toolkit and the network clock is enabled.

Any help would be appreciated as I'm racking my brains trying to figure it out

 

Hi I only have 1 power supply unit, the C-bus toolkit says current consumption 212ma and current supply 600ma. Looking at the power supply it says supplies 200ma to network. I think I would be close if not just over that. If so its a shame as its a lot of money for an extra power supply

 

Hi Waynebr,

You're probably on top of this already but:-

Just on the 'get it going' now angle, you could leave one or two units disconnected and use Toolkit to configure all but them. Then disconnect something else, reconnect those other two and configure them (so database has all units). Ensure you have a clock and a burden enabled somewhere other than the PCI, then take the PCI offline and plug all the rest back in.

This should just get it all running as the PCI draws a hefty 32ma from the c-Bus. When you need to program something, just disconnect something whilst you're doing it. Not ideal by a long shot but will get you going till your PSU arrives.


On the PSU front, if you had been considering adding soon to your c-Bus network, something like a new dimmer unit, new relay unit or multi-room audio switch, you could bring forward that purchase and buy that instead of just a stand-alone power supply which is quite expensive just to add a power supply.

This way you are getting extra functionality and not just shelling out for power supply.

DIN rail dimmer or relay with inbuilt PSU = 200ma
Stand-Alone c-Bus PSU = 350ma
Clipsal MRA switch = 330ma

That still leaves a whole 10ma spare, plenty!!

Oops, Just as I thought..................I'm living in the past ..........


Waynebr, I'll do you a great deal on my old version MRA matrix switcher with power supply so I can get a new one. I've got power to burn and not enough new MRA matrix switches!!

All the best,

Brad

 

Thanks I already have an opus 300 system installed, I guess the only option will be to buy a power supply. Currently I have 4 Blind relays, 1 8 channel 1 amp dimmer with power supply, 1 without power, 4 channel 2amp dimmer without power, 2 4 key DLT, 3 4 key saturn.

Guess the extra units take me over my allowance.

 

Yes, the project is saying 212ma current consumption in Toolkit which is over the 200ma provided by the one in-module supply.

With the PCI removed from the network it would be only 190ma, which is under and though this will allow your network to run as it is today, it is not a long term 'solution'.

regards,

Brad
