ts_sensor_over_
temperature
The Process Temperature
input exceeds
the Temperature Upper
Range Limit
(URL) as determined by
the configured
Sensor Type.
Check the process
temperature. If the
process temperature
exceeds the range of
the current sensor type,
either correct the
process to an in-range
temperature or switch to a
different sensor type which
is ranged for the expected
process temperature
range.

calibration correcs on LRV,
URV or both is in excess.
Perform Reset Corrects to
reset the User calibration
to factory default. If

Fault is set if Temperature
module
• input failue faulty sensor,
• out of range
• input open
Replace the faulty sensor if
that is the reason. Select
suitable sensor type for the
process. Reset the device,
replace the Temperature
Module if issue persists
