11.2.4.4 High set point
The high set point for the digital output is set here.
Setting range:
0 to 8000 ml/s in steps of 0.01 ml/s.
0 to 900 l/min in steps of 0.01 l/min.
Factory setting: Max. flow from the measurement device (de-
pendent on the nominal size)
– DN10 = 350 ml/s
– DN15 = 600 ml/s
– DN20 = 1000 ml/s
– DN25 = 4000 ml/s
– DN32 = 300 l/min
– DN40 = 480 l/min
– DN50 = 900 l/min
11.2.4.5 Pulse valence
This specifies for which flow rate an output pulse is emitted.
The setting must be selected so that the max. output fre-
quency of the product (10 kHz) as well as the max. input fre-
quency of control unit are not exceeded. The pulse pause ra-
tio is 1:1. The pulse length is restricted to 1 s.
Example: 2.0 ml/Imp.
This means: A pulse is emitted every 2.0 ml.
Setting range: 0.1 to 3000.0 ml/Imp, in steps of 0.1 ml/Imp
Factory setting: 1.0 ml/Imp.

quency

100 1 100 0.01 0.005 5
1000 0.1 10000 0.0001 0.00005 0.05
100 10 10 0.1 0.05 50
0.5 10 0.05 20 1 1000
In the last case, a pulse with a duration of 1 second is emitted
every 20 seconds.
11.2.4.6 Operating quantity counter
The operating quantity counter can be displayed in the menu.
The unit is set at m³. This counter is unidirectional and can
therefore deviate from the daily quantity counter.
The operating quantity counter cannot be set to zero.
11.2.4.7 Daily quantity counter
The daily quantity counter is the one which appears in the dis-
play as standard. The unit corresponds with the one that is
set. The behaviour of the daily quantity counter

Once the daily quantity counter has reached 1,000,000 litres, it
starts counting again at zero. However, the operating quantity
counter continues to run without reset.
