Table 3 Warning list for the sensor
Warning Description
CL CAL A chlorine and/or pH calibration is
RECD recommended.
The chlorine and/or pH measurement
has changed enough to cause a Cal
Watch warning alarm to occur. Refer
to the sensor manuals for more
information.
CL CAL A chlorine calibration is recommended.
RECD
Chlorine calibration data is not
available (sensor with default
calibration data).
CL CAL TO The Sensor Days value for the
DO chlorine sensor is greater than the Cal
Reminder value.
CL MAINT Chlorine sensor maintenance is
RECD recommended.
The slope is 30 to 45% of default or
the slope is 250 to 300% of default.
The default slope is 100 mV/ppm
(100%).
CL MAINT Chlorine sensor maintenance is
RECD recommended.
The offset is -50 mV to 45 mV or the
offset is 45 mV to 50 mV.

Event log

The controller provides one event log for each sensor. The event log
stores a variety of events that occur on the devices such as calibrations
done, calibration options changed, etc. A list of possible events is shown
below. The event log can be read out in a CSV format. For instructions
on downloading the logs, refer to the controller user manual.
