The second selection from the Settings Screen, number 1 key, allows the user to
change the operating mode of the AL250-V2; Sanitize, Standby or Operating
(Tank/Direct Feed) modes. The third selection, number 2 key, allows access to the
Settings data entry screens. The user is prompted for the access code to enter sub
menu 0 (Clock) or 2 (Settings) of the Settings screen (factory default access code =
12345).
NOTE:
Standby mode is selected from the Operating Mode screen (selection “1”
from the Settings screen). Tank or Direct feed operation is selected from first setting
(Index 0) from the list of settings accessed by selecting “2” from the Settings screen.
The fourth selection, number 3 key, automatically initializes the modem. This only
needs to be done one time after a modem is installed in the controller.
The fifth
selection, number 4 key, allows the user to select the data log interval.
The sixth
selection, number 5 key, erases the data currently in the data logger.
Upon entering the Settings data entry screens (by pressing “2” from the main
Settings screen), the user will have the option of entering an index number for a
particular setting. This enables the user to go directly to a particular setting without
scrolling through the entire list of settings. Alternatively, the user may scroll through
the settings with the up and down arrow keys.

information on that particular setting.
