4 Function
4.1 Process measured signals
The unit displays the current process values�
It generates 2 output signals according to the parameter setting�
OUT1: 3 selection options Parameter setting
- Switching signal for volumetric flow quantity limit value (→ 10.2.1)
- or pulse signal for quantity meter (→ 10.3.1)
- or switching signal for preset counter (→ 10.3.2)
OUT2: 4 selection options Parameter setting
- Switching signal for volumetric flow quantity limit value (→ 10.2.2)
- or switching signal for temperature limit value (→ 10.4.1)
- or analogue signal for volumetric flow quantity (→ 10.2.3)
- or analogue signal for temperature (→ 10.4.2)
- or input for external reset signal (InD) (→ 10.3.7)
If not used as an output, OUT2 (pin 2) can instead be used
as an input for an external reset signal
(→ 10.3.7)
4.2 Volumetric flow monitoring
The volumetric flow is monitored by an ultrasonic measuring system, the meas-
ured signals are evaluated by the electronics�
The signals for measuring the volumetric flow quantity can be provided as follows:
1� Two switching signals for volumetric flow quantity limit values on output 1 and
output 2 (→ 4.5)�
2� An analogue signal proportional to the volumetric flow (4���20 mA or 0���10 V)
on output 2 (→ 4.6)�
4.3 Consumed quantity monitoring (totaliser function)
The unit has an internal quantity meter which continuously totals the volumetric
flow quantity� The sum corresponds to the current consumed quantity since the
last reset�
• The current meter reading can be displayed�
• In addition the value before the last reset is saved� This value can also be
displayed�
