Status Display Error Code Details
Error Code X101
Dirty Window Detected

Dirty front Sensor optics detected. Clean Sensor front window and
mirror. This will only be seen on Sensors with the Dirty Window
Detector Option
Error Code X102 Out of calibration (M56)
Do not Initiate a Calibration Check during
warm-up. See Section 5.5 Warm-up and
Initial Setup , page 85, for M52, 5G, and 5R
models.

Calibration check has sensed Sensor out of calibration condition

Note: An out of calibration error may be encountered if the Sensor
temperature is too high or too low. Do not calibrate when an
Alarms for error codes X103, X104, X105, X106 exist.

Caution: Any temperature readings at Analog Output or from RS-
485 Communications must be considered inaccurate

Check Sensor Calibration on a Blackbody Standard
Error Code X103 Detector block too hot

Detector Temperature is too high.

Check ambient temperature (55 °C maximum) and Sensor internal
case temperature using the RS485 RC Command or with a
temperature measuring device such as a fine thermocouple. If
these temperatures are okay and alarm continues Sensor may
have a malfunction.

Caution: Any temperature readings on rear panel display, at
Analog Output or from RS-485 Communications may be
inaccurate.
Error Code X104 Detector block too cold
Note: This Error Code is normal during
Sensor warm-up. Warm-up typically lasts
from just a few minutes to 15 minutes.

Detector Temperature is too low

Check ambient temperature (0°C minimum) and Sensor internal
case temperature using the RS485 RC Command or with a
temperature measuring device such as a thermocouple.

If these temperatures are okay and alarm continue, check the
24VDC supply voltage. Sensor may have a long warm-up time if
the voltage not within 5%.

If the power supply is remotely installed, insure the voltage drop
across power supply wires is not causing a low voltage level at the
Sensor.

Caution: Any temperature readings on rear panel display, at
Analog Output or from RS-485 Communications may be
inaccurate.
Error Code X105 Case temperature too high

Sensor case temperature is below is above specification.

Check ambient temperature (55 °C maximum) and Sensor internal
case temperature using the RS485 RC Command or with a
temperature measuring device such as a thermocouple. If these
temperatures are okay and alarm continues Sensor may have a
malfunction.

Caution: Any temperature readings on rear panel display, at
Analog Output or from RS-485 Communications may be
inaccurate
