SOFTWARE VERSION AA
This version of software functions similarly to AA with the
following differences:
1) The SEIZE input no longer disables the AUTO function when pressed.
2) The SEIZE input can
also
be used
as
a MAINTAINED input. That
is,
if
the SEIZE input pin is held LO (to ground) for more than about seconds,
the hybrid will turn on (obviously) but will
off
(release the line) when
the SEIZE input returns to a logic HI
3)
The DROP input will not disable the AUTO function while the SEIZE
input is held LO, but will turn the hybrid off still.
If the SEIZE input
is used
for momentary action, however, the DROP input will disable the auto
functions just like AA
This means that the operator can still enable and disable the auto
function from a momentary LO signal on the
AUTO
pin while the SEIZE input
is
being held LO. If the DROP input
is
brought LO while the SEIZE input
is
being held
LO, the hybrid will
turn off but the auto function cannot be toggled
anymore
via
the
AUTO
input. The auto function will remain in the state it
