Beer volume indication.
The Beer volume indicator is a device to give the consumer an impression about the amount of Beer left in the KEG.
This indicator is not accurate only steps of 25 % are possible to display.
From WK532 onwards the software has been upgraded to version 6.4.
The volume indication levels are improved from 4 to 8 levels.
This results in more accurate volume indication.
For revision changes (See page 14 for the explanation/description!)
When the consumer is complaining about the fact that the display indicates a empty KEG but there is still Beer left in the KEG
this is actually not a failure in the appliance.
When less then 30 % of the volume is measured by the system the display will indicate 0 %.
(OLD version before WK532, see revision changes page 14 for the explanation/description)
Other complaints of the consumer could be that the display shows 100 % volume, but there is already Beer out of the KEG.
If for some reason the appliance has been
switched off
or a
voltage dip
has occurred in the mains network or the
KEG has been
removed
and replaced again, the system will start with a
100 % volume indication
.
After pouring one or two glasses of Beer, the volume indication will be recalculated and displayed.
If the volume indication is for some reason not thrust full, the cause could be that there is an air leakage in the system.
In that case most likely parts to check are Beer
tube connector
,
KEG
or
Adaptor
. See under
Trouble shooting point 3 Blinking
display or pump is “to” often activated. (Air Leakage)
.
9.
No foam on the Beer.
If the complaint is that there is “almost” or no foam on the Beer, the following have to be checked.
1) Temperature of the Beer must be below 9° C, check DFU for more tips.
2) Glasses have to be clean, check DFU for more tips!
3) Beer tube connector is not properly installed or is damaged, check DFU for more tips.
10.
To much foam.
If the complaint is that there is to much foam on the Beer, the following have to be checked.
1) Temperature of the Beer must be below 9 °C, check DFU for more tips.
2) The Beer tube is not properly installed or is damaged, try new Beer tube.
3) There must be no air leakage in the system.
11.
Avoiding ticking noise/signal of starting pump.
If consumers are complaining about a ticking noise when the pumps start running the following can be done to solve the
problem.
The problem is caused by the fact that when the pumps start running it hits a screw of the drop ring fixation of the pump.
See location for the drop ring in below picture.
The problem can be solved by removing the screw, see picture above.
Removing the screw does not harm or affect the strength of the construction.
