• [FEPx] defines the upper measured value at which the output signal has the
frequency set under FrPx.
– FEPx is only available for flow measurement in the operating mode GAS.
Minimum difference between FSP2 and FEP2 = 20 % of the final value of
the measuring range.
If the measured value is outside the measuring range or in the event of an internal
error, the frequency signal indicated in the following figure is provided.
For measured values outside the display range or in case of a fault, messages are
displayed (UL, OL, Err).
The frequency signal in case of a fault is adjustable
• [FOU] = On: In case of a fault the frequency signal goes to the upper end stop
value (130 % FrPx).
• [FOU] = OFF: In case of a fault the frequency signal goes to the lower end stop
value (0 Hz).
• [FOU] = OU: The frequency signal still corresponds to the measured value.
