2.06 Setting Scale
Analog Output 1
The scale of the analog output is used to set the maximum value. The maximum value is set slightly
higher than the highest possible occurring flow rate. If the value
0
is entered here, Analog output 1 is
deactivated and 0 V or 4 mA respectively is output.
2.07 Setting Averaging
Analog Average
The averaging allows for a stable display with varying flow amounts. Possible values, adjusted to the
requirements, are between 1 and 10000. In case of averaging the display of quick changes takes
place with a time delay.
Examples of reaction time for a change of 99.9 % of the actual frequency jump:

No filter is active for Averaging 1. A V
Z
1 filter is active as of Averaging 2. In the process the old meas-
ured value is weighted higher by the averaging value than the new measured value. Averaging of the
display is also active on the Modbus.
2.08 Setting Scale
Pulse Output 1
The scale of the pulse output is used to set the pulse significance. Since the pulse values can also be
output in packets, the manufacturer recommends using the pulse output only for total values.
Select the scale so that the limit frequency of 250/125 Hz is not exceeded.
0
Pulse output is switched off. No pulses are output anymore.
Note:
After the setting has been changed, the electronic unit has to be restarted.
After the system password 1919 was entered in
2.01 Setting Enable Password
the pulse with can be
set to 2 - 200 ms in
0.09 Pulse output pulse width setting
.
2.09 Setting Display
Start Message
Activate or deactivate the start message.
2.10 Setting Address
Modbus
The transfer of data by means of the Modbus is possible via the serial interface. The address can be
set here.
Note:
Data exchange via the Modbus connection is not password-protected! Write access deletes existing
values. Therefore the manufacturer only recommends reading of the data.
2.11 Setting Function
Pick up
The pulse input must be adjusted to the pick up used.
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
