Startup Issue

I have two networks, with the second network having 30 shutter controllers all located together and their c-bus cables daisy-chained between each unit (so there is no' external' cabling in this network outside the box). There are three c-bus power supplies on the network, so power is not an issue. Clocks are enabled on the bridge and two shutter relays and the burden is enabled on the bridge.

When this network is initially powered on more often than not, three or four of the relays will not come online ie: there is no c-bus or unit light. These can be units between other units, so the c-bus signal is passing through, to the next unit but the unit itself has no c-bus light on.

In order to get all units with their c-bus and unit lights active and present on the network the power needs to be cycled three of four times. During each cycle different units go on and different units will stay off.

On the other network, there are 9 relays, 15 dimmers, 34 key inputs etc etc (88 units in total). This network never appears to have a problem when first powered up.

Is it something to do with the shutter controllers startup sequence? - too many of the same unit trying to do the same thing at the same time? Why would some units (and not always the same ones) not initialise whilst most others do and what does the power cycling do other than randomly allow them all to eventually come online?

Thanks.

P.S. Once all units are on the network is completely stable, so it is only the startup that is odd.

 

Can you give a little more info about the install?
- Firmware version of Shutter Relays
- Firmware version of Bridge
- Reported network voltages across the units
- Version of Toolkit used to program them

 

Hi Newman,

See below.

Suggest you give tech support a call. They have seen this before and have sorted it out in the past.

 

abg let us know how you sorted it.

 

Logged with CIS this afternoon. Will let you know how it goes.
