AOF
When AOF is off, the engine controller is unable to start the Night/Off Mode. The user should
keep AOF on ( > System Settings > Key Operator Tools > AOF).
Timers
The engine controller references the Energy Saver Timer to start the Low Power Mode, and
references the Auto Off Timer to start the Night/Off Mode. The user can set these timers (
> System Settings > Timer Settings).
The Energy Saver Timer and the Auto Off Timer start at the same time (t
0
) when the machine
ends all jobs or when the user ends all manual operations. Note that the Auto Off Timer does
not wait for the Energy Saver Timer. Therefore, if the user specifies a smaller value in the
Energy Saver Timer, the Auto Off Timer expires earlier than the Energy Saver Timer. In a
case like this, the Low Power Mode is not activated. Instead, the engine controller starts the
Night/Off Mode when the Auto Off Timer expires.
