Symptom
Cause
Corrective Action
Temperature reading indi-
cates maximum when
temperature is actually
less.
Wired sensor is shorted
Wired sensor cable has a short.
Sensor has failed
Ensure that the sensor connection is not shorted.
A short equals zero resistance and thus the max-
imum value.
Replace damaged cable.

Temperature reading indi-
cates minimum when tem-
perature is actually
greater.
Wired sensor is not connected
Wired sensor cable has an open.

Ensure that the sensor is connected to the cor-
rect header pins. An open connection equals an
infinite resistance and thus the minimum value.
Replace damaged cable.

Temperature display does
not equal actual tempera-
ture.
Incorrect sensor programmed
Verify the actual sensor connected to the sensor
input is programmed appropriately. Each temper-
ature sensor is limited to a specific operating
range.
Display flashes repeat-
edly between the Winland

Cycle power to the EA800 and wait for a period
of time before reapplying power.
If a USB drive is attached to the USB port,
remove it and cycle power as noted above.
If the problem recurs, contact Winland Technical
Service at 1-800-635-4269.
