4.1 Process measured signals
The unit displays the current process values�
It generates 2 output signals according to the parameter setting�
-
OUT1: Analogue signal for temperature limit value (→ 10.2)
-
OUT2: Analogue signal for volumetric flow limit value (→ 10.3)
4.2 Volumetric flow monitoring
The volumetric flow is monitored by an ultrasonic measuring system, the meas-
ured signals are evaluated by the electronics�
An analogue signal which is proportional to the volumetric flow (4���20 mA) is
provided on output 2 → 4.4.
4.3 Temperature monitoring
An analogue signal which is proportional to the temperature (4���20 mA) is pro-
vided on output 1 → 4.4.

MEW = Final value of the measuring range
ASP = Analogue start point: determines at which measured value the output signal is 4 mA�
AEP = Analogue end point: determines at which measured value the output signal is 20 mA
