Note 1: The fault diagnosis output turns on in case of
input burnout, A/D converter failure, or reference junction compensation (RJC) failure. The
control output in case of input burnout or A/D
converter failure is set to the value of the PO
(Preset Output Value) setup parameter. In case
of RJC failure, the controller continues control
under the condition of “RJC = OFF”.
Note 2: The FAIL output is on during normal operation
and turns off in case of failure.

Changing the registered value of a setup parameter
may cause the registered value of an operating parameter to be initialized automatically. Thus, when
you have changed a setup parameter, always check
that the registered value of the operating parameter
is appropriate. If it is initialized to default, reset it to
the required value.
