If there is an alarm, the module has at least one of the following errors:
Tipo di errore
Input error
Loss of data error /
Input
temperature-
acquired error
If the amplitude of the acquired input signal IN is between the input start scale and input end
scale, the output is directly proportional to the input.
If the amplitude of the acquired input signal IN exceeds the interval [input start scale - 2.5 % of
input scala range, input end scale + 2.5 % of input scala range], the LED ALARM switches
from turned off to turned on and the software signals that there is a input error.
If the amplitude of the acquired input signal IN decreases into the interval [input start scale
-2.5 % of input scala range, input end scale + 2.5 %of input scala range], the LED ALARM
switches from turned on to turned off and the software signals that there isn't a input error.

IN
If the amplitude of the acquired input signal IN exceeds the hardware module limits too (see
the following table), the software will also signal that there is a error fail.
Descrizione
The amplitude of the acquired input signal is
less than (greater than) the input start scale
(end scale) or the TC/RTD sensor is damaged
The cold-junction internal sensor is damaged Thermocouple
