LED DISPLAY, INDICATORS AND KEYBOARD
DIGITAL DISPLAY
The digital readout will indicate the Chlorine concentration of
the last sample measured in milligrams per liter (mg/L) dur-
ing normal operation.
Only when a key is pressed to execute some other function,
will the concentration reading be interrupted. In this case, the
Chlorine mg/L indicator is turned off.
If the Chlorine concentration is above 5 mg/L, the display will
blink.
mg/L CHLORINE INDICATOR
During normal operation, this green indica-
tor will be on continuously, indicating that the
LED is displaying Chlorine concentration. Dur-
ing the diagnostic or other modes this indicator
will be off.

When proportional dosing is active, the dose
LED will be on and the corresponding relay
closes. This LED turns off automatically when
the proportional dosing stops.
ALARM INDICATOR
This LED will be on when the programmed
alarm setpoints are exceeded. The alarm
LED turns off automatically when the alarm
