Shutdown is delayed during a re-start in order
to guarantee restart of multiple paralleled

Fold-down.
Default state – hiccup mode
System Start-up A 20 second shutdown delay is implemented to allow modules to be plugged in
one at a time. During this time fold-down occurs but the module will not shut
down below 39Vdc.

Hiccup performance attempts automatic recovery from an overload shutdown with approximately a 90% off-time duty cycle. The
duty cycle varies periodically in order to guarantee multi-module recovery synchronization. Latchoff can be chosen via software
instead of the default hiccup. Recovery from a latchoff requires ENABLING, or software commanding OFF followed by an ON
after a 2 second delay.
