The feed tube serves two purposes. One end of the tube
has a hole and the other end does not.
1. Normal Operation
During normal operation the end of the feed tube with
the hole is placed into the mix inlet hole. Every time
the draw handle is raised, new mix and air from the
hopper flow into the freezing cylinder. This keeps the
freezing cylinder properly loaded and maintains
overrun.
2. Long No Sale Periods
During long no sale periods, the machine can be
placed in the Standby mode. This maintains product
temperatures below 40°F (4.4°C) in both the hopper
and the freezing cylinder and helps prevent
overbeating and product breakdown.
To place the machine in the Standby mode, press the
STANDBY key. Remove the air orifice. Lubricate the
O-rings on the end of the feed tube without the hole.
Place that end of the tube into the mix inlet hole. This will
prevent any mix from entering the freezing cylinder.
Note:
The air orifice is used to meter a certain amount
5
of air into the freezing cylinder. The air orifice maintains
overrun and allows enough mix to enter the freezing
cylinder after a draw.
Operating Screen Descriptions
The fluorescent display in the center of the control panel
is normally blank during the daily operation of the
machine. The display is activated when the SEL symbol
or the Manager's Menu is selected. The display screen
will also alert the operator of specific faults detected by
the control.
Power Up
When the machine is powered, the control system will
initialize to perform a system check. The screen will
display INITIALIZING. There are four types of data the
system will check: LANGUAGE, SYSTEM DATA,
CONFIG DATA, and LOCKOUT DATA.
During the INITIALIZING... LANGUAGE screen, the
alarm will be on. If the system detects corrupt data during
INITIALIZING, the following display will alert the operator
that the control settings may have been changed:
5-4
RESET TO DEFAULTS
See NVRAM FAULT for instructions if the above
message appears on the screen.
Once the system has initialized, the SAFETY TIMEOUT
screen will display and the alarm will be on.
ANY KEY ABORTS
The SAFETY TIMEOUT screen will be displayed with the
alarm on for 60 seconds or until any control symbol is
selected.
After the safety timeout has been completed and the
power switch is OFF, the following screen is displayed:
POWER SWITCH OFF
Power Switch ON
When the power switch is placed in the ON position, the
control panel press keys become operative. The
fluorescent display will either be blank or indicate that the
machine has been cleaned.
Brush-Clean Counter
The brush-clean counter (item 9 on page 5-1) will display
the number of hours since the freezer was last
brush-cleaned. After hour 99, it will change to a letter and
a number. (Example: A0, A1, B0, B1, etc.)
