Transfer bus off annunciators

[Phil Waecker]

Hello,

I have one question concerning the Transfer Bus annunciators on the 737
panel.

Those are defined as textlightboxes with the following var transbus1=off. If
I understand correctly this means it lights when transbus1 value is set to
off. Up to there no problem.
What I don't understand is that when we cut the power, batt to off the
transbus1 variable is off but it doesn't light !

How is this done ?

Regards

Phil

Hi Phil,
it is done inside pmSystems.
When Batt1 is switch to OFF all TextLightBoxes and Gauges are going to OFF,

also if they are in the background are ON.

Thanks very much for this answer ! I was suspecting something like that but
had never been confronted to the problem before. Since I am now connecting
the overhead to IOCards hardware I noticed that those transfer bus lights
remained always on !

Nice evening

Hi Phil,
I use also IOCards (with SIOC) and Phidgets.
I will upload in some days a new 737NG098-file, there I use new Offsets:
TransBus1Fault, ....
Because I had the same problem, so I changed the logic.
