...The problem that I am having is that accessory relays 1-6 on each of the AIU's are only turning on to a momentary closure when selected and triggered. Relays 7-10 respond and latch on as expected.

I don't have an answer but would like to understand the problem.

For ACC relays 1-6, are you saying you press the "ON" softkey on the DCS remote but the relay only turns on momentarily (rather than latching to ON)? If so, is the momentary closure always the same duration...like the 1/2 second "tick-tock" clicking you hear from the AIU enclosure when triggering an SW relay?

Do the misbehaving ACC 1-6 relays correctly respond to the "ACT" momentary softkey?
