Head On / Disabled
This button will disable the fill head in case of mechanical or electrical problems that prevent the head
from operating properly. By disabling the head the rest of the fill heads can still be used. It is not
necessary to place a bottle in the head before disabling it.
Shuttle Off / On
When the shuttle is turned off it no longer returns to the forward or front position in the machine. This
function is useful if you are not crowning your product such as cans, growlers or Champagne style bottles
with corks. This reduces the cycle time of the machine by not shuttling back and forth.
Crowner Off /On
When the machine is first turned on the default setting is crowner off. This allows the operator to set up
the machine before crowning. It also allows products that do not require crowns to be filled. Once the
crowner is turned on a crown time menu appears.
Crown Time
Use this menu to set the amount of time the crowner stays in the down time. Set the time to allow a good
crown usually about 1.5 seconds. Excess time will increase your overall cycle time.
Purges
The number of purges for each head is set with this menu. The purge cycle consists of one Co2 pressure
and one vacuum draw. Typical number of purges is two. More purge cycles will increase cycle time.
Purge Time
During the Purge cycle as well as the Counter pressure cycle this timer is used to set the time allowed for
the pressure or vacuum set point to be reached. It is also used as a timer to clear a bridge prior to the
purge cycle. If the set point cannot be achieved during this time the cycle aborts and the head returns to
the up position and the shuttle comes forward. If the Co2 and air regulators are set properly the minimum
value of 5 seconds is sufficient to achieve the set points. If filling large bottles such as growlers or 5 liter
cans more time is required to achieve the set point especially during vacuum. Setting this value higher
allows more time before the cycle aborts. This time value does not control the length of the actual cycle
during normal operation. The switching between Co2 pressure and vacuum is controlled by the pressure
switch. If for some reason the pressure or vacuum set point cannot be achieved such as a missing,
cracked or broken bottle, a bridge in the head or a leaking fill head the higher value will only delay the
aborting of the cycle. This value should only be increased when the container being filled cannot reach
the set point within the 5 second minimum due to it's large size.
Start All / 1
This controls the number of bottles that start once the Start Switch has been pressed. In the "
ALL
"
position, all the bottles start at once. This is the most productive format to use the machine. By selecting
the"1" position Head 1 starts first. Once the fill cycle starts, Head 2 starts and the rest of the heads
follow. This is sequential filling which is useful when first setting up the machine. It gives the operator
time to observe each head and ensure it is operating properly. Due to the sequential starting of each
head the overall cycle time in increased.
