4.1 Process measured signals
The unit displays the current process values�
It generates 2 output signals according to the parameter setting�
OUT1: 4 selection options
Parameter setting
-Switching signal for volumetric flow quantity limit value → 10.3.1
-or switching signal for flow velocity limit value → 10.3.1
-or pulse signal for quantity meter → 10.4.1
-or switching signal for preset counter → 10.4.2
OUT2: 6 selection options Parameter setting
-Switching signal for volumetric flow quantity limit value → 10.3.2
-or switching signal for flow velocity limit value → 10.3.2
-or switching signal for temperature limit value → 10.5.1
-or analogue signal for volumetric flow quantity → 10.3.3
-or analogue signal for flow velocity → 10.3.3
-or analogue signal for temperature → 10.5.2
If not used as an output, OUT2 (pin 2) can instead be used
as an input for an external reset signal
→ 10.4.7
4.2 Volumetric flow monitoring
The volumetric flow is monitored by a calorimetric 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) 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�
