5.
THERMISTOR OPEN—
One or both of the barrel
(freezing cylinder) thermistor probes are faulty.
6.
SYRUP PRESS LOW—
When the syrup-out indicator
displays a lack of syrup, a 15-minute internal timer
will start. At this time, no refrigeration or product flow
from the flow control will be allowed. Only the beater
and CO
2
operate. If the syrup is not replenished at
the end of the 15 minutes, the freezing cylinder will
shut down and this fault message will appear.
Replenishing the syrup will cause the fault message
and warning tone to clear. If using a tank system,
priming may be required. (The example shown is for
the right side.)
7.
CO
2
PRESSURE LOW—
When the CO
2
-out
indicator displays a lack of CO
2
, a 60-second internal
timer will start. If the CO
2
is not replenished at the
end of the 60 seconds, both freezing cylinders will
shut down and this fault message will appear.
Replenishing CO
2
will cause the fault message and
warning tone to clear.
8.
H
2
O PRESSURE LOW—
When the water-out
indicator displays a lack of water, a 60-second
internal timer will start. If the water is not replenished
at the end of the 60 seconds, all freezing cylinders
will shut down and this fault message will appear.
Replenishing the water will cause the fault message
and warning tone to clear.
9.
BARREL NOT COOLING—
A freezing cylinder
check has been established for the Auto mode of
operation. If a freezing cylinder enters the Auto
mode, the control will check product temperature.
After 5 minutes, it will again check product
temperature. If product temperature does not drop in
that 5-minute time span, the freezing cylinder will
shut down and this message will appear on the fault
screen. For this check to be valid, the product
temperature must be above 40°F (4.4°C), and the fill
switch cannot be activated. If a fill condition exists
during this time, the 5-minute check will be re-
initiated.
10.
BARREL TEMP 2 HIGH—
A maximum allowable
product temperature has been established to prevent
product from excessive heating. If the product
exceeds 120°F (49°C) for any reason (in any mode of
operation), the entire machine shuts down.
Faults, when corrected, are cleared from the fault
description screen, with the following exceptions:
BARREL NOT COOLING and
BARREL TEMP 2 HIGH.
These faults require the operator to press the OFF key
(when in the FAULT DESCRIPTION
screen) in order for
the fault to discontinue.
To see if there is more than one fault in either freezing
cylinder, press the PLUS key. To return to the Operator
Menu, press the SELECT key once. To return to the Main
Screen, use the right arrow key to cycle to MENU ITEM
A, then press the SELECT key.
