contacts are still connected and active unless set to OFF
in either of the modes.
8.5.1.3 Analog Outputs
Analog outputs of either 4-20 mA or voltage are avail-
able. If you select voltage you may choose 0-10V, 0-1V
or 0-100mV. This analog output will be shared by both
modes and will automatically recalibrate to the selected
mode.
8.5.1.4 Serial Port (Optional)
If a serial port is connected the readings will report in
NTU while in the turbidity mode and will report in %T
while in the backwash mode.
8.5.2 OPERATION
With the remote switch set to the normal position
(open), the instrument should be calibrated in both
turbidity and backwash. All parameters such as alarm
set points and display limits should be set as described
in the O&M Manual. Press
key to return
to the main menu. At any time, from this point on, you
may set the remote switch to the backwash position
(closed) and change over to the backwash display.
While in either mode any operating parameter may be
changed by pressing and entering the
access code. Keep in mind that even while in the menus,
all outputs are still active in which ever mode you were
last in.
CAUTION: Keep in mind that when changing modes, the
alarms, the analog output and the serial port (if
connected) will also change modes.
