4�7 Frequency Output - Autosen AS005 Notice D'utilisation

4.7 Frequency output
The unit provides a frequency signal that is proportional to the volumetric flow and
the medium temperature�
Within the measuring range the frequency signal is between 0 and 100 Hz for the
factory setting�
The frequency signal is scalable:
• [FrPx] determines the frequency signal in Hz provided when the upper
measured value (MEW or FEPx) is reached�
The measuring range is scalable:
• [FSP2] determines the lower temperature value from which a frequency signal
is provided�
FSP2 is not adjustable for flow measurement�
• [FEPx] determines at which measured value the frequency signal is FrPx�
FEPx is not available for flow measurement in the operating mode
[ModE] = REL�
Minimum distance between [FSP2] and [FEP2] = 20 % MEW�
If the measured value is outside the measuring range or in the event of an internal
error, the frequency signals indicated in figure 2 are provided�
For measured values outside the display range or in case of a fault, messages are
displayed (UL, OL, Err; → 13).
The frequency signal in case of a fault is adjustable (→ 10.4.8):
• [FOU] = On determines that the frequency signal goes to the upper final value
(130 % FrPx) in case of an error�
• [FOU] = OFF determines that the frequency signal is 0 Hz in case of an error�
