Information
Temperature
module ADC
Reference
Failure
The reference
voltage
measurement in
one of the two
Analog to Digital
Converter (ADC)
parts in the
Temperature module
is not operating
correctly. The
process temperature
measurement may
be affected.
Reset the device. If
the problem persists,
replace the
Temperature module.

Unreliable
Communication
If there is no proper
communication
between
Communication
Board and
Temperature Sensor
Board (Terminal) or
invalid data on
communication line
due to noise
User can verify the
cable/connector
between
communication and
Temperature sensor
board (Terminal
Board) to ensure that
it is not damaged.
Check for bent pins.If
cable/connector is not
the problem, replace
the Communication
module.If problem still
persists, replace the
Terminal board.

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.
