Technical Information
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 -
SONDA CELLA DIFETTOSA - 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).
16.4 - Door micro-switch alarm
Cause: Active input for more that 5 minutes (uF parameter)
with maching 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 “PORTA
APERTA - 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.
16.5 - Alarm - Differential Thermal Breaker - Oil Pressure
Cause: When the input alarm is activated for more than 5
seconds.
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 -
MAGNETOTERMICO-PRESS. OLIO - BREAKER - OIL PRESS”.
Flashing RED symbol (14).
Reset: Pressing the off beeper alarm silencer button and
alarm cause disappearance.
16.6 - Automatic reset minimum pressure switch alarm
Cause: When the machine is in start the alarm input is
activated for more than 5 seconds (with machine in STOP it
is not activated). The alarm is inhibited for approximately 2
minutes with each compressor start. The alarm is inhibited
during “pump downs”.
Effect: It places the machine in STOP. Inhibition of the
Start/Stop and Defrost buttons.
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 “AL07
- PRESSIONE MINIMA - MIN. PRESSURE”. Flashing RED
symbol (14).
Reset: Pressing the off beeper alarm silencer button or
switching off and switching on the card again (stand-by).
16.7 - Automatic reset Kriwan Alarm
Cause: When the input is activated with machine in start
for more than 5 seconds, at least 3 times in the same cycle.
Effect: Each time only the compressor stops and starts up
again when the input is activated. Upon the third time the
machine is placed in STOP.
Beeper: The beeper sounds (3 seconds and then pauses
for 30 seconds) until the silencer button is pressed.
Display/LED: If the Kriwan alarm is activated, for the two
times only the word “Kriwan” appears, alternatinf with
the Temperature and Time values represented, without
locking the machine but only the compressor. Upon the
third time the scrolling text “AL08 - KRIWAN COMPRESSORE
- COMPRESSOR KRIWAN” will appear. Flashing RED symbol
(14).
Reset: Pressing the off beeper alarm silencer button or
switching off and switching on the card again (stand-by).
16.8 - Input alarm HT1 - fusable
Cause: When the alarm is activated for more than 5
seconds.
Effect: Electrical disconnection of certain components
downstream of the fuse.
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 “AL09 -
CAMBIA FUSIBLE - REPLACE FUSE”. Flashing RED symbol
(14).
Reset: It resets itself when the status of the input is
activated.
16.9 - Overtemperature alarm
Cause: The overtemperature alarm is activated (only
during the storage) when the cell probe detects a certain
temperature value time greater than the sum of the positive
or negative storage set with the relevant alarm delta
(parameter A2 or parameter A4). The overtemperature
alarm is in any case disabled for a certain length of time
(parameter 5) from the start of the storage phase and after
a defrost. This alarmis not activated/managed if the cell
probe is in alarm.
Effect: Storing of the alarm is the HACCP memory together
