Power Controller Warm Boot
A "warm boot" occurs under one of the following conditions:
-
Power has "grayed out", ie. not completely failed. This most commonly occurs on the DIN relay or -48 power switch if a marginal input power supply voltage (below 8V for DIN and -30V for -48 switch) is applied and relays are turned on, reducing input voltage even further. It can also occur in battery powered applications as the batteries fully discharge.
-
The internal watchdog processor has detected an error (including low input voltage) and rebooted the main control processor.
-
The user has performed a firmware upgrade and that upgrade has successfully completed.
Firmware versions 1.5.8 and later can trigger a script after a warm boot.
