E.1.4 Power Failure
If power fails to the keypad display (but not to the DL8000 itself) for
more than 5 seconds or if communications fail to the keypad display for
more than 5 seconds, the system generates the Keypad Display
Communications Failure (K & D Com. Fail) alarm (if you have
previously configured it [TLP 64,0,42]).
In the event of power failure, the program redisplays the screen when
power is restored. If the preset was in program mode when the power
failure occurred, the keypad display program exits program mode and
redisplays the most previous loading mode screen.
In the event of communications failure, the program redisplays the
screen when communications are restored. If the preset was in program
mode, the keypad display program exits program mode and redisplays
the most previous loading mode screen.
