4.1.26. VAPOUR RECOVERY SYSTEM HISTORY (P33, P34)
The parameter is used to display the last 40 fillings on nozzles with activated vapour recovery for filling point A
(P33) or B (P34). Records are only stored if the internal vapour recovery monitoring system is activated. After
switching to parameter P33 (vapour recovery system history for filling point A), the display shows the vapour
recovery values for the last delivery. The amount display line shows the percentage feedback factor value to
one decimal place (see P36 for more information). The quantity display line shows the vapour / fuel ratio in
percent with one decimal place. After pressing the <+> key, the penultimate filling appears. After pressing the
<E> key, the date and time of the end of the saved delivery will appear on the display.
Parameter
Meaning
(P)33
Vapour recovery system history for filling point A
(P)34
Vapour recovery system history for filling point B
Example: According to the last record (00), fuel delivery took place on 24.8.2021 at 12:51:01, during which the vapor recovery feedback
factor was 98.0% and the ratio of the volume of extracted vapours to the volume of flowed fuel was 102.5%
4.1.27. AVERAGE VALUE OF VAPOUR/FUEL RATION (P35)
The parameter is used to display the average value of the ratio of the volume of extracted vapors to the volume
of fuel dispensed. The average is calculated from the last 40 fillings for filling points A and B. After switching to
parameter P35, the display shows the average volume ratio value for filling point A (P35‐A). The quantity display
line shows the vapour/fuel ratio in percent with one decimal place. After pressing the <+> key, the average ratio
value for filling point B (P35‐B) appears.
Parameter
Meaning
P35‐A
Average value of vapour/fuel ration for filling point A
P35‐B
Average value of vapour/fuel ration for filling point A
Example: The average value of the ratio of the volume of extracted vapours to the volume of dispensed
fuel for filling point A is 102.5%
NOTE
The average value should be between 95% and 105%. If the value is lower than 95%, it probably means a
problem with the vapor recovery vacuum pump or dirt in the VR piping. If the value is higher than 105%, then the
regulation (VR solenoid valve) may not work properly.
4.1.28. AVERAGE VALUE OF VAPOUR RECOVERY FEEDBACK FACTOR (P36)
The parameter is used to display the average feedback factor of the vapour recovery system. The average is
calculated from the last 40 fillings for filling points A and B. After switching to parameter P36, the display shows
the average value of the feedback factor for filling point A (P36‐A). On the quantity display line, there is a
percentage factor with one decimal place. After pressing the <+> key, the average factor value for filling point B
(P36‐B) appears.
Parameter
Meaning
P36‐A
Average value of vapour recovery feedback factor for filling point A
P36‐B
Average value of vapour recovery feedback factor for filling point B
Example: The average value of the vapour recovery feedback factor for filling point A is 98.0%
