Sensor Tempera- ture Error
Optima Non-latching
Sensor fault or warning code (Note 4)
Check location for heat sources. Fit with sunshade or other protection. Change location of the transmitter. Check tem- perature in Info->Sensor Status to ensure temperature is being measured properly.
Sensor Tempera- ture Error
Excel Non-latching
XNX polls sen- sor every 2 sec- onds, diagnos- tic frequency controlled by sensor
Sensor fault or warning code (Note 4)
Check location for heat sources. Fit with sunshade or other protection. Change location of the transmitter. Check tem- perature in Info->Sensor Status to ensure temperature is being measured properly.
Sensor Tempera- ture Error
ECC Non-latching 2 seconds Sensor temperature (Celsius)
Check location for heat sources. Fit with sunshade or other protection. Change location of XNX. Check temperature in Info->Sensor Status to ensure tempera- ture is being measured properly.
F125
Calibration Re- quired
All Non-latching 2 seconds
Number of days remaining until calibration expires, negative = number of days expired
Time since the last span calibration has exceeded a defined limit. Performing a successful span calibration will clear the condition. The limit is the maximum calibration interval.
F126
Sensor Path Ob- scured
Optima Non-latching
XNX polls sen- sor every 2 sec- onds, diagnos- tic frequency controlled by sensor
Sensor fault or warning code (Note 4)
Check location for external interference. Check sensor for dirty windows.
