ALARMS
Summarized here are the main alarms that can appear
and that will be represented by the scrolling text on the
display:
Evaporator probe alarm - AL01
Cause: being outside the operation range (-58°F (-50°C) /
212°F (100°C)) for more than 30 seconds.
Effect: Interruption of any defrosting in progress. Inhibition
of all periodic defrosting. Inhibition of manual defrosting
(except forcing of fans with machine at standstill).
Beeper: The beeper sounds (3 seconds then pauses for 30
seconds) until the silencer button is pressed.
Display: The display shows the scrolling text “AL01 - FAULT
EVAPORATOR PROBE”. Flashing RED symbol (14).
Reset: It resets by itself if the value of the probe falls
(approximately 20 seconds), or if the probe is excluded
with parameter “/5”.
Product probe alarm - AL02
Cause: being outside the operation range (-58°F (-50°C)
/ 212°F (100°C)) for more than 30 seconds with a
temperature chilling cycle in progress.
Effect: Interruption of the temperature chilling cycle in
progress resulting in automatic start of Time chilling.
Inhibition of all periodic defrosting. Inhibition of
temperature chilling button.
Beeper: The beeper sounds (3 seconds then pauses for 30
seconds) until the silencer button is pressed.
Display: The display shows the scrolling text “AL02 - FAULT
PRODUCT PROBE 1(2)”. Flashing RED symbol (14).
Reset: Press the alarm silencer button (with beeper off)
or proceed with parameter “/9” (temperature chilling
disabled).
Cell probe alarm - AL03
Cause: being outside the operation range (-58°F (-50°C) /
212°F (100°C)) for more than 30 seconds.
Effect: If START is given to a positive chilling (both with Time
and Temperature) or if the latter is already in progress, it
immediately goes into pause-work positive storage mode
(C5 and C6 parameters).
If START is given to a negative chilling (both with Time
and Temperature) or if the latter is already in progress, it
continues (as it is not conditioned by the cell temperature
until passing into negative storage which will be in pause-
work mode (C5 and C7 parameters)). If the event takes
over during storage, this continues in pause-work mode.
Beeper: The beeper sounds (3 seconds then pauses for 30
seconds) until the silencer button is pressed.
Display: The display shows the scrolling text “AL03 - FAULT
ROOM PROBE”. Flashing RED symbol (14).
Reset: It resets by itself if the value of the probe is
activated.
NOTE: With cell probe anomaly it is in any case possible
to perform RUN+HARD chilling (compressor goes into
continuous mode).
Door micro-switch alarm - DOOR OPEN
Cause: Active input for more that 5 minutes (uF parameter)
with machine in start.
Effect: The blast chiller behaves as described in the
section “7 Door Opening 7”.
Beeper: The beeper sounds (3 seconds and then pauses
for 30 seconds) until the silencer button is pressed.
Display: The display shows the scrolling text “DOOR
OPEN”. The symbol (14) flashes YELLOW.
Reset: Press the alarm silencer button (with beeper off),
or it resets by itself if the input status is activated.
Differential Thermal Breaker - Oil Pressure - AL06
Cause: When the input alarm is activated for more than
5 seconds. Possible power surge - activating the thermo
switch. Possible condenser build-up - not allowing proper
cooling.
Effect: It places the machine in STOP. Inhibition of all
the buttons except that of silence/reset, entering the
parameter menu and ON/OFF
Beeper: The beeper sounds (3 seconds and then pauses
for 30 seconds) until the silencer button is pressed.
Display/LED: The display shows the scrolling text “AL06 -
BREAKER - OIL PRESS”. Flashing RED symbol (14).
Reset: Pressing the off beeper alarm silencer button and
alarm cause disappearance.
Course: Switch OFF THE MACHINE. Remove the frontal air
inlet. Take out the electrical power box and remove the
cover of the power box. Find out the magnetothermic
switch and restore it manually (reset button).
NOTE: CV15E-2 does not have an Oil Pressure Switch
installed.
Automatic reset minimum pressure switch alarm - AL07
Cause: When the machine is in start the alarm input is
activated for more than 5 seconds (with machine in STOP it
