Backup Operation

While the Controller is running, if the input voltage to the Energy Pack falls below 20 Vdc,
the Energy Pack will immediately switch to backup power and signal the Controller to
initiate a memory backup.
The Energy Pack supplies power long enough for the Controller to back up memory and then
turns off power to the Controller. When the input voltage to the Energy Pack returns to
normal, the power-up routine begins.
