THERMISTOR SHORT— One or both of the barrel
(freezing cylinder) thermistor probes are faulty.
THERMISTOR OPEN— One or both of the barrel
(freezing cylinder) thermistor probes are faulty.
SYRUP PRESS LOW— When the syrup out indicator
displays a lack of syrup, the barrel will enter a hold
mode. At this time, no refrigeration or product flow
from the flow control will be allowed. Only the beater
will operate. When the syrup is satisfied the barrel
will refill the product tank and then automatically
return to the Auto mode. The fault message and the
warning tone will clear. (See “Syrup Out Indicator” on
page 5-7.)
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. Replenish the
CO
2,
and the fault message and warning tone will
clear.
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.
Replenish the water and the fault message and
warning tone will clear.
BRL 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 five-minutes, it
will again check product temperature. If product
temperature does not drop in that five-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).
BRL 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 unit shuts down.
Faults, when corrected, are cleared from the Fault
Description screen, with the following exception: BRL
