Power-up
When power is applied to the Energy Pack, the power-up process goes through the following steps:
1.
The IN LED turns on green.
2.
The Energy Pack performs a self-diagnostic test. If this test passes, output power to the Controller is turned on
and the OUT LED turns on green.
3.
Charging of the Cap Pack begins and the STAT LED blinks green.
4.
When charging of the Cap Pack is complete, the STAT LED turns on solid green and the Energy Pack signals to
the controller that it can start run-time operation. The Controller will not start running its application until the
Energy Pack signals that it is fully charged.

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.
