2.10Setting Number of
decimal places
Select number of decimal places. 1 - 3 decimal values are available. Display without decimal place is
not possible.

The following are available:
o NPN
o PNP
o Namur
For push-pull pick ups you can either use NPN or PNP .
Note:
With this setting you can also switch the supply voltage for the pick up Ä Technical data,Page5.
2.13Setting Function
pulse inputs
Counter
Flowmeter with pick up is used.
Encoder
Flowmeter with two pick ups is used (flow direction detection option).
2.14Setting Link
channel
Selection of the link when using two flowmeters
A-B
Differentiation calculation for consumption measurement
A+B
Sum calculation for combination of two measuring sections
2.15Setting Threshold
value A-B
The threshold value is required for consumption measurement when the consumer is switched off and
the circulation pump continues to run. The threshold is used to suppress small amounts resulting from
measuring errors.
The threshold should be selected clearly lower than the lowest possible consumption.
Threshold = 0
Function is deactivated.
Threshold > Consumption Q
o Display in 1.01Consumption display = 0
o Totaling of T1 and T2 in 1.02Display total is stopped. All other values are not influenced!
