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.
