4.4.3  Consumed quantity monitoring via pulse signals

Every time the flow rate set with [ImPS] has been reached (pulse value), the 

output provides a pulse signal�

OUT1 and OUT2 cannot be used simultaneously for the pulse output�

4.4.4  Consumed quantity monitoring via preset counter

When the flow rate set under [ImPS] has been reached, the output provides a 

switching signal� 
The setting of the parameter [rTo] defines if the volumetric flow quantity has to 

be reached irrespective of the time (1) or within a set time (2) so that the output 

switches:

• The output switches when the 

volumetric flow quantity set with 

[ImPS] has been reached�

• The output remains switched 

until the counter reset�

• The preset counter is only reset

 -when a manual reset is made 

(→ 10.3.3)

 or

range has been exceeded

• The output switches only when 

the volumetric flow quantity set 

with [ImPS] is reached within 

the set time�

• The output remains switched 

until the counter reset�

• If the output is not switched, the 

preset counter is automati-

cally reset when the time has 

elapsed and the count starts 

again

• If the output is switched, the 

preset counter is only reset�
