4.3 Analogue output
The unit provides an analogue signal that is proportional to the volumetric flow
quantity or the medium temperature�
Within the measuring range the analogue signal is 4���20 mA�
The measuring range is scalable:
• [ASP2] determines at which measured value the output signal is 4 mA�
• [AEP2] determines at which measured value the output signal is 20 mA�
Minimum distance between [ASP2] and [AEP2] = 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 current signal indicated in Fig� 1 is provided�
For measured values outside the display range or in case of a fault, messages are
displayed (cr�UL, UL, OL, cr�OL, Err;
→ 12
)�
The analogue signal in case of a fault is adjustable
(→ 10.5.11)
:
• [FOU] = On determines that the analogue signal goes to the upper final value
(21�5 mA) in case of an error�
• [FOU] = OFF determines that the analogue signal goes to the lower final value
(3�5 mA) in case of an error�
• [FOU] = OU defines that in case of a fault the analogue signal reacts as defined
by the current parameters�
