DL122 Quick-Start Hardware Setup
1) Plug the pH probe into the BNC connector on the controller.
2) Insert the 4GB SD card (included),
printed side down
, making
certain that it snaps into place.
3) Connect RJ11 temperature probe.
4) Connect one end of RJ45 power cable to the DL122 unit; the
other end to the Controller power box. To avoid “accidental”
dosing, you will not be plugging the Controller power box into
a power supply until the settings for pH have been entered and
saved.
5) Connect 9VDC power supply into unit first, then plug into
120VAC wall outlet.
Note: To enable Wi-Fi, you will need to know your Wi-Fi network
Security Type, Name, and Password.
Milwaukee Instruments, designer and manufacturer of the
DL122, recommends you read this manual from start-to-
finish, without skipping sections. Many of the instructions in
later sections are based on knowledge you will acquire in the
earlier sections of this manual.
Getting to know the DL122
Once you have connected all the cords, inserted the SD card, and
plugged the DL122 into a wall socket, please read this section,
taking a few moments to learn about the screen and keypad.
Note there is no ON/OFF switch; the unit is ON as soon as it is
plugged in. The only way to deactivate the unit is to unplug it.
Recorded data on the SD card will remain intact when the unit is
unplugged.
THE SCREEN When the unit is first powered up, you will see a
WELCOME message. In a few seconds, the unit will automatically
switch to the primary display screen. This screen gives the date,
time, and real-time readings of pH and Temperature. If activated,
the word Wi-Fi will appear in the upper right corner. Unless you
are changing settings, this is the screen that should always be
displaying.
Primary Display Screen
If temperature probe is plugged in, ATC (Automatic Temperature
Compensation) will appear in the lower right portion of screen.
If not, MTC (Manual Temperature Compensation) will display.
On the menu screens, only four lines will be visible at a time.
To see more options, scroll the list by using up/down arrows
on the keypad. When the cursor (>) appears beside the
appropriate function or setting, press SELECT.
THE KEYPAD
Pressing the Menu button brings up a screen
featuring the full menu. At the bottom of all menu screens,
there will be an “Exit” option. The “Exit” option, when selected,
takes you back to the previous screen you were viewing. For
informational screens, there is no “Exit” option. Press SELECT to
return to previous screen.
Pressing the Menu button takes you all the way back to the
primary display screen, bypassing other screens you may have
used. Pressing the Menu button also allows you to toggle
between the primary display screen and the full menu screen.
The left/right arrows ( ) allow you to move the blinking cursor
horizontally through a line of settings to the numbers you want
to reset, while the up/down arrows (
) allow you to move
through the function listings and numbers, and toggle between
yes/no options. When new settings are entered, press SELECT,
there will be a short pause and the screen will read SAVED! In just
a moment, the unit will revert to the previous screen.
The Lights button allows you to turn off the screen and status
lights (lights to the left and right of screen, behind grills). The
unit is still functional when lights are off. Pressing Lights again
will reactivate all lights.
IMPORTANT: When in the Lights OFF mode, the status lights
(caution and critical) will not activate on the unit; however,
since the unit is still operational, it will continue to log data
and, if web portal is activated, send text or email alerts, or
both. The only way to turn off data logging and the alerts
system is to unplug the unit.
The Snap Shot button allows you to instantly log a real-time
reading on both the SD card and the portal. A snap shot will
not interfere with scheduled data logging. When you press the
Snap Shot button on the keypad, “Snap Shot” will appear for a
few seconds in the lower right corner of the screen, indicating
the real-time data has been logged.
