RE: CBUS Bus Coupler and light programming problem

["Andrew Walker" <andrew.walker@xxxxxxxxxxxx>]

Cheers Phil,

I just got a reply actually, but yes I used the normally closed contacts
so it would "make" when the door was opened.

I should be OK with this reply, CBUS forums are saying:-

Ok, the method depends on the version of bus coupler you have.
The latest version has support for Bi-stable switches, which should be
perfect for you, so hopefully that's what you've got!

BCN4B (v2.2.0):
Your toggle switch is really working like a bi-stable switch, so in the
Key Functions tab select the "Bistable Switch" tick box for the
appropriate channel.
When the door is opened, the Just Closed, then Closed micro functions
will be triggered (think switch closed, not door!).
Make the Just Closed micro function "Up Key" to give your ramp on
over 4
seconds (set RR accordingly in Global tab).
Make the Closed microfunction "Retrigger Timer" and set your 2
minute
timer and "Off Key" timer expiry function on the appropriate
block.

For the turn off, set the "Just Opened" microfunction to
"Off Key" and
you should be done!


KEYBC4 (v1.2.67):
This doesn't support bistable switches, so it's a little less
intuitive...
When the door is opened, you get a Short Press, then a Long Press event.
When it closes you will get a Long release event (unless you close it
with ~400ms...), so:
Make the Short Press micro function "Up Key" to give your ramp on
over 4
seconds (set RR accordingly in Global tab).
Make the Long Press microfunction "Retrigger Timer" and set your
2
minute timer and "Off Key" timer expiry function on the
appropriate
block.

When the door is closed you will get a Long Release or (very rarely) a
Short release event, so set both of these microfunctions to "Off
Key".

You need to set the button action on the bus coupler to be a bell press
rather than a toggle however if the momentary switches that you are
using on the doors are "make" when the door is closed and
"break" when
the door is open then you may find that the action is the wrong way
round and the light only comes on when the doors are closed...
