Important
Only bit 0/ 3 is relevant for the purposes of evaluation in the process input
•
image. You can use bit 0/ 3 to monitor the temperature of a motor, for example.
Bit 0/ 3 in the process input image does not have a retentive function. Make
•
sure at parameter assignment that motor start-up is controlled (by means of an
acknowledgment), for example.
For security reasons, always evaluate the diagnostic inputs of the 2AI RTD
•
High Feature because measurement is not possible when the EM is removed,
when the power supply to the EM has failed, or in the event of a wire break or
short-circuit of the measuring lines.
