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: 4 selection options

Parameter setting

-Switching signal for volumetric flow quantity limit

value

(→ 9.2.2)

-or switching signal for flow velocity

(→ 9.2.2)

-or pulse signal for quantity meter

(→ 9.3.1)

-or switching signal for preset counter

(→ 9.3.2)

OUT2: 6 selection options

Parameter setting

-Switching signal for volumetric flow quantity limit

value

(→ 9.2.3)

-or switching signal for flow velocity limit value

(→ 9.2.3)

-or switching signal for temperature limit value

(→ 9.4.1)

-or analogue signal for volumetric flow quantity

(→ 9.2.4)

-or analogue signal for flow velocity

(→ 9.2.4)

-or analogue signal for temperature

(→ 9.4.2)

If not used as an output, OUT2 (pin 2) can instead be

used as an input for an external reset signal�

(→ 9.3.5)

4.2 Volumetric flow monitoring

The volumetric flow is monitored by a calorimetric measuring system, the meas-

ured signals are evaluated by the electronics�

•

2 switching signals for volumetric flow limit values can be provided (output 1

and output 2). On the switching functions → 4.5.

•

An analogue signal which is proportional to the volumetric flow (4��20 mA) can

be provided on output 2. On the analogue functions → 4.6.

4.3 Consumed quantity monitoring

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�
