User Interface
Display: 16 character backlit LCD display
shows real time sensor readings, alarms,
programming values and menus.
Keypad: 7 pressure sensitive keys for setting
calibration, control setpoint, alarms, 4-
20mA, triggered timer, totalizer, and sensor
clean values. UP, DOWN, PREV, and ENTER
keys for scrolling through menu and
changing settings. CAL button for single
point calibration. SETPOINT for changing the
control value. MENU for more detailed
configuration.
Options
Automatic sensor washing: Recommended
for high TDS applications such as recirculated
cooling water. On-line sensor washing is
available by requesting the optional
diaphragm pump and tank package (part no.
7149002).
Sample flow switch: The optional sample
flow switch assures that when the sample
stream is interrupted for any reason, the
feed of chemicals is halted. This is a valuable
safety device as well as a way to prevent
overfeeding of chemical due to a trapped
“dead” sample.
