EZ Pressure Setup
This button controls a popup menu used to measure the tank pressure of the product being filled. This in
turn sets the counter pressure used during the fill cycle and controls when the beer valve is opened.
When the button is pressed the following menu is displayed:
Pressure in the bottle being filled should be equal to or slightly less than the pressure in the
product tank. This will allow product to flow into the bottle as soon as the product valve opens.
The flow should not cause any foaming and should not go up the fill tube or feed line. The menu
box “
Open Below Pressure
” allows the operator to enter a differential pressure between the
counter pressure in the bottle and the pressure in the tank. The value entered into this register is
subtracted from the actual tank pressure and this is the pressure at which the beer valve opens
as seen in the “
open=**.* psi
” menu box. The EZ pressure setup measures the pressure in the
tank and automatically counter pressures the bottle to a higher setting. The vent valve then
opens allowing pressure to slowly bleed out of the bottle. Once the pressure in the bottle is equal
to the “
open=**.* psi
setting, the valve opens allowing product to flow into the bottle.
To check the tank pressure, a bottle or can must be placed in the left hand (#1) filling station. The
shuttle is moved to the back position and the fill head lowered. Once the “
Press to Start
” button is
pressed, beer flows into the bottle until the pressure in the bottle is equal to the tank / keg
pressure. The pressure reading on the display will stabilize displaying the tank pressure. Press
the “
Set Pressure
” button and the pressure value is first subtracted from the “
Open Below
Pressure
” value and then transferred to menu box “
open = **.* psi
”. The pressure differential
should be between 0 & 2 psi. depending on the conditioning of the beer. Experiment with
different values.
NOTE
: There are several ways to position the bottle to measure the tank pressure. First place a
bottle on the shuttle for filling station one.
1) Disable Head 1 with which puts the bottle in the desired position.
2) Another is to power the machine down with a bottle in filling station 1 and power back up
again.
