Modline 5

Measurement status displays for Out of Range and Invalid measurement conditions are defined as
follows:
LOW
Conditions do not allow measurement because the infrared temperature signal is too low.
The target temperature is too low for the range of the Sensor.
HIGH
Conditions do not allow measurement because the infrared temperature signal is too high.
The target temperature is too high for the range of the Sensor.
INV
Measurement Conditions are invalid for two color ratio temperature measurement.
When the Invalid Alarm (iALM) function is set to ON, this measurement condition
becomes an alarm and triggers the Alarm relay and the ALARM word on the Sensor rear
panel.
If INV is the only Alarm, pressing the
▲
pushbuttons will show no other Error
Codes.
The above conditions may relate to improper installation or adjustment of Sensor
Functions. Avoid reflections from surrounding hot objects, unresolved targets, and
obstructions in the Sensor’s optical path. True temperature measurement is dependent
on correct setting of Emissivity or E-Slope.
Use of Pick Picker or Track and Hold signal conditioning may be necessary to capture
temperature signals because of process interferences.
The Rear Panel ALARM indicator signals an error has been detected. Press Up Arrow
▲
to view Error
Codes.
Press Up Arrow
▲
multiple times to view all simultaneous Error Codes.
Error Codes for Sensor diagnostic information are summarized as follows:
X101
Dirty Window Detection
X102
Out of calibration
X103
Detector block too hot
X104
Detector block too cold
X105
Internal Case temperature too high
X106
Internal Case temperature too low
X107
Sensor failure. FAIL may be seen on the Sensor TEMP display
X108
Analog Output Current loop malfunction
X109
Dirty Window Detection malfunction
pINV
pINV is only displayed when the Invalid Alarm (iALM) function is set to ON and Peak
Picker or Track and Hold is On. This condition becomes an alarm and triggers the Alarm
relay and the ALARM word on the Sensor rear panel.
Temperature displayed is Peak Picked or Hold Mode Temperature values from prior valid
measurement conditions.
Environmental conditions can cause Sensor errors. High or low ambient
temperatures can cause Sensor case temperature too high or too low errors. Dirty
lens conditions can be avoided using air purging.
