Table 7 Warning list for conductivity sensors (continued)
Warning Description Resolution
CAL OVERDUE The Cal Reminder time
has expired
Calibrate the sensor.
NOT
CALIBRATED
The sensor has not been
calibrated
Calibrate the sensor.
REPLACE
SENSOR
The sensor has been in
operation > 365 days
Calibrate the sensor with a
reference solution and reset
the sensor days. Refer to
Sensor diagnostic and test
menu on page 16. If the
calibration fails, call technical
support.
CAL IN
PROGRESS
A calibration was started
but not completed
Return to calibration.
OUTPUTS ON
HOLD
During calibration, the
outputs were set to hold for
a selected time.
The outputs will become active
after the selected time period.
WRONG LINEAR
TC
The user-defined linear
temperature compensation
is out of range
The value must be between
0 and 4%/°C; 0 to 200 °C.
WRONG TC
TABLE
The user-defined
temperature compensation
table is out of range
The temperature is above or
below the temperature range
defined by the table.
Event list for sensors
The event list shows current activities such as configuration changes,
alarms, warning conditions, etc. To show the events, press the MENU
key and select Sensor Diag, [Select Sensor], Event List. A list of possible
events is shown in Table 8. Previous events are recorded in the event
log, which can be downloaded from the controller. Refer to the controller
documentation for data retrieval options.
Table 8 Event list for conductivity sensors
Event Description
CAL READY The sensor is ready for calibration
CAL OK The current calibration is good
TIME EXPIRED The stabilization time during calibration expired
CAL FAIL The calibration failed
CAL HIGH The calibration value is above the upper limit
K OUTRANGE The cell constant K is out of range for the current
calibration
UNSTABLE The reading during calibration was unstable
CHANGE IN CONFIG float The configuration was changed—floating point type
CHANGE IN CONFIG text The configuration was changed—text type
CHANGE IN CONFIG int The configuration was changed—integer value type
RESET CONFIG The configuration was reset to the default options
POWER ON EVENT The power was turned on
ADC FAILURE The ADC conversion failed (hardware failure)
FLASH ERASE The external serial flash memory erase occurred
TEMPERATURE The temperature is out of range (-20 to 200 °C)
SAMPLE CAL START Start of calibration for conductivity
SAMPLE CAL END End of calibration for conductivity
ZERO CAL START Start of zero calibration
ZERO CAL END End of zero calibration
