key and select Sensor Diag, Warning List. A list of possible warnings is
shown below.
Table 3 Warning list for the sensor
Warning Description Resolution
CL CAL
RECD A chlorine and/or pH calibration is
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. Calibrate the chlorine
sensor and/or pH
sensor.
CL CAL
RECD A chlorine calibration is recommended.
Chlorine calibration data is not
available (sensor with default
calibration data). Calibrate the chlorine
sensor.
CL CAL TO
DO The Sensor Days value for the
chlorine sensor is greater than the Cal
Reminder value. Calibrate the chlorine
sensor.
CL MAINT
RECD Chlorine sensor maintenance is
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%). Do sensor
maintenance and then
repeat the calibration,
or replace the sensor.
CL MAINT
RECD Chlorine sensor maintenance is
recommended.
The offset is -50 mV to 45 mV or the
offset is 45 mV to 50 mV. Do sensor
maintenance and then
repeat the calibration,
or replace the sensor.
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.
