PV-INPUT.-.Indication.of.the.signal.type.for.the.process.actual.value
The PV INPUT function specifies the signal type of the process actual value:
• Unit signal
• Frequency signal
• Circuit with PT 100
Factory setting: 4 – 20 mA
When the operating voltage is switched on, the device searches for excluded sensor types (automatic sensor
detection).
When a sensor type is detected (Pt100 or 4 – 20 mA), the signal type is automatically implemented in the
PV-INPUT operating menu.
The frequency signal of the signal type cannot be detected automatically, but must be set manually in the
PV-INPUT operating menu.

PV-Scale.-.Scaling.of.the.process.actual.value
The PV-SCALE function specifies the following settings:
• The unit of the process actual value.
• The position of the decimal point.
• The values for the lower and upper process actual value.
If the settings for the unit of the process actual value or the position of the decimal point are input or
changed, this setting applies to all scaling values (SPmin, SPmax, PVmin, PVmax).
