6.3.9
Pulse outputs (level 24 and 25) (only displays 2 and 3)
6.3.9.1
Original pulses
Irrespective of the operating mode, only the pulses which reach pulse input “A” are output as
original pulses. The pulse duration for original pulses is always 4 ms and cannot be altered.
6.3.9.2
Scaled pulses
Depending on the volume/quantity of mass, pulses can be output at the pulse output. A pulse is
always followed by a pulse-pause of identical duration (Ratio 1:1).
The following pulse durations can be selected in level 25:
Pulse duration [ms]
4
12
24
48
100
Max. output frequency [Hz]
125
42
21
10
5
Select the type of pulse output in level 24::
0: Original pulses
1-6: Scaled pulses
OFF: No pulse output
Pulses are not lost. If the max. output frequency is briefly exceeded due to an excessive flow
rate, the pulses are metered in a “pulse buffer”. This buffer outputs the remaining pulses
once the flow rate has been reduced.
The display (V1) is used to determine the scaling.
Definition of the positions for the following explanations:
Position 1 = far right, Position 2 = second from right, etc.
Example 1:
Setting “1” has been selected in level 24 (= position 1):
Meter reading (V1): 01357.246 kg
If position 1 changes from 6 to 7, the pulse buffer increases by 1.
The pulse buffer increases by 1 every time position 1 changes.
The pulses are output immediately.
Example 2:
Setting “4” has been selected in level 24 (= position 4):
Meter reading (V1): 01357.246 m³
If position 4 changes from 7 to 8, the pulse buffer increases by 1.
The pulse buffer increases by 1 every time position 4 changes.
Example 3:
Setting “4” has been selected in level 24 (= position 4):
The pulse buffer increases by 10 pulses if position 5 changes from 5 to 6, since this repre-
sents a 10 step change to position 4. The pulses are output immediately.
Clever selection of the scaling factor (level 24) and the pulse duration (level 25) can help to
achieve a high resolution without reaching the maximum output frequency of the meter.
Caution:
Subsequent changes to the number of digits after the decimal point for the volume can affect
the output of the scaled pulses! The setting in level 24 must then be corrected.
