The LED lights after power-up tests OK and the BIM operating system is
running. Flashing (P1 BIM only) indicates that the address key is not
inserted or is not being read correctly.
For future use.
Light up at an irregular rate to indicate communication on the bus.
ON 24 Vac bus voltage is in the acceptable range.
OFF 24 Vac bus voltage is outside the acceptable range, indicating
insufficient or shorted supply of the I/O bus,
or one of the AC/DV converters is faulty.
ON 24 Vac (supply voltage) input present; fuse is intact.
OFF No 24 Vac (supply voltage) input,
or fuse is blown.
ON V (field supply voltage) input present; fuse is intact.
OFF No V (field supply voltage) input,
or fuse is blown.
