Table 6 Warning list (continued)
Warning Description Resolution
The device is not
calibrated. The sensor has not been calibrated. Calibrate the sensor.
Replace a sensor. The Sensor days counter is more
than the interval selected for sensor
replacement. Refer to
Configure the
sensor on page 8.
Replace the sensor. Reset the Sensor days
counter on the Diagnostics/Test > Reset
menu (or Diagnostics/Test > Counter menu.
Calibration is 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. As an alternative,
remove and then supply power to the
controller.
Linear temperature
compensation is out of
range. The user-defined linear temperature
compensation is out of range. The value must be between 0 and 4%/°C; 0 to
200 °C.
Temperature
compensation table is
out of range. The user-defined temperature
compensation table is out of range. The temperature is above or below the
temperature range defined by the table.
6.6 Event list
The diagnostic bar shows current activities such as configuration changes, alarms, warning
conditions, etc. A list of possible events is shown in
Table 7 . 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 7 Event list
