The F197 is a manual set-point generator. The operator enters an analog or a scaled output value or a percentage which will be transmitted as a (0)4 – 20mA or 0 – 10V DC signal to a control device. If available, the F197 can also display the measured actual process value. However, there is no direct control relationship between the input and output value. Further, one low and one high alarm value can be set with an alarm ignore function to monitor the process.
The display shows the pre-set value, actual value and status simultaneously. On-screen engineering units are easily configured from a comprehensive selection.
