BLF modes

[cecilia.dellaria@statewide.com]

I have been looking for a list of BLF mode conditions. I know using a BLF Mode 0 has the blfs show green if not in use, and mode 1 turns the light off if not in use. I've been trying to figure out what the other options are, but cannot find a list.
Mode 0 BLFs are green when not in use
Mode 1 BLS are blank when not in use
Mode 2 ?
Mode 3 ?
Mode 4 ?

Can anyone fill in the chart? Or give me a link to explain the different modes?

Thanks,
Cecilia
