AUTOFLUSH: (0-10 minutes) This is the length of the flush cycle. The
system will flush for this amount of time every hour in tank feed and
standby modes.
D. Timer Screen
Pressing either the ACCEPT or the RESET button from the configuration screen
brings up the timer screen. The controller has three timers (hour meters). Two
are user resetable and one is not. All of these timers count up when the pump is
running. The two user resetable meters are labeled PREFILTER and
MEMBRANE. Pressing the reset button when either of these timers are
highlighted will reset the timer to zero. The SELECT button moves the highlight
cursor to the next timer. Press Accept while the membrane meter is highlighted to
exit and return to the operation screen.
E. Calibration Screen
This screen is used to calibrate the conductivity and temperature. Press ACCEPT
and RESET at the same time to bring up this screen. The temperature and
conductivity fields on the last two lines of the display can be adjusted using the up
and down arrows. Use the arrow keys to input the correct temperature and then
press the ACCEPT button. The conductivity will now be highlighted. Use the
arrow keys to input the correct conductivity and press the ACCEPT button.
Always calibrate the temperature first. (Note: the new values are only saved when
the ACCEPT button is pressed while the field is highlighted.) When the desired
values are entered press the RESET button to return to the operation screen. You
can only enter the calibration screen if the conductivity and temperature readings
are stable.
F. Pop-Up Screens
Under certain circumstances a pop-up screen may be displayed. These look like a
window that partially blocks out the screen behind it. The conditions that display
pop-up screens are:
Low Inlet Pressure
Pretreatment Interlock
Overload Conditions
Trying to calibrate if the temperature and/or conductivity is not stable.
