SIGNALS
Indications
a cycle/phase of cold-storing is on run
a cycle/phase of quick-cooling/freezing is on run
a Hard-Soft quick-cooling modality is selected
a Manual Ventilation is on run
the modality of quick-cooling/freezing for temperature was selected
the modality of quick-cooling/freezing for time was selected
the instrument is ready to execute the count of a time but the conditions
do not permit it (a defrost cycle is on run or the temperature read by the
needle probe is not lower the set established with the parameter "c8")
the instrument is on
a count of a time is on run
a defrost cycle is on run
a delay count at the defrost cycle activation is on run (parameters "C0",
"C1", "C2", and "d1")
Alarms
on the indicator DY 1 flashes
the indication "E0" and the buzzer
is activated with intermittent beep
(cabinet probe failure)
on the indicator DY 1 flashes
the indication "E1" alternated to a
temperature value and the buzzer
is activated with intermittent beep
(evaporator probe failure)
on the indicator DY 1 flashes
the indication "E2" and the buzzer
is activated with intermittent beep
(corrupted memory data
alarm)
ALARMS (1/3)
Causes
the kind of cabinet probe is not
proper, the cabinet probe is defec-
tive, the connection instrument-
cabinet probe is not proper, the
temperature read by the cabinet
probe is outside the limits permit-
ted by the cabinet probe in use
the same saw in the preceding case
but referred to the evaporator probe
there is a failure of memorised
configuration data
Remedies
check if the cabinet probe is a PTC
probe, check the integrity of the
cabinet probe, check the correct-
ness of the connection instrument-
cabinet probe, check if the tem-
perature near the cabinet probe is
inside the limits permitted by the
cabinet probe in use
the same saw in the preceding case
but referred to the evaporator probe
try to switch the power supply off
and then switch it on: if the alarm
persists also to the instrument re-
start it is necessary to change the
instrument
Effects
if the alarm happens during the
status "STOP" it does not permit
the start of a cycle of quick-
cooling/freezing; if the alarm hap-
pens during a cycle of quick-
cooling/freezing it immediately
ends the cycle; if the alarm hap-
pens during a cycle of cold-stor-
ing the compressor output is
activated with the modality estab-
lished with the parameters "C5"
and "C6" (or "C7")
the defrost ends for maximum
length (parameter "d3")
if the alarm happens during the
status "STOP" it does not permit
the start of any cycle of function-
ing; if the alarm happens during
the status "START" it immediately
ends the cycle, all the outputs are
deactivated
