Alarms
on the indicator DY 1 flashes
the indication "E3" alternated to a
temperature value and the buzzer
is activated with intermittent beep
(needle probe failure)
on the indicator DY 1 flashes
the indication "E4" alternated to a
temperature value and the buzzer
is activated with intermittent beep
(locking input on alarm)
on the indicator DY 1 flashes
the indication " " and the buzzer
is activated with intermittent beep
(needle probe test failure)
on the indicator DY 1 flashes
the indication "End" and the
buzzer is activated with intermit-
tent beep for some seconds (cy-
cle of quick-cooling/freezing for
temperature successfully)
on the indicator DY 1 flashes
the indication "End", on the indi-
cator DY 2 appears the indica-
tion "0" and the buzzer is activated
with intermittent beep for some
seconds (cycle of quick-cool-
ing/freezing for time success-
fully)
on the indicator DY 1 appears
a temperature value, on the indi-
cator DY 2 flashes the indica-
tion "0" and the buzzer is activated
with intermittent beep (cycle/
phase of quick-cooling/freez-
ing out of maximum length)
on the indicator DY 1 appears
the indication "End", on the indi-
cator DY 2 flashes the indica-
tion "---" and the buzzer is acti-
vated with intermittent beep (cy-
cle of quick-cooling/freezing
failed and out of maximum
length)
ALARMS (2/3)
Causes
the same saw for the cabinet probe
failure but referred to the evapora-
tor probe
the high-pressure input is on
the test to verify the proper position
of the needle probe is failed (pa-
rameters "c7" and "CE")
a cycle of quick-cooling/freezing
for temperature has successfully
finished
a cycle of quick-cooling/freezing
for temperature has successfully
finished
the temperature read by the needle
probe has not reached the set es-
tablished with the parameter "c2"
(or "c5") inside the maximum length
established with the parameter "c1"
(or "c4")
the temperature read by the needle
probe has reached the set estab-
lished with the parameter "c2" (or
"c5") out of the maximum length
established with the parameter "c1"
(or "c4")
Remedies
the same saw for the cabinet probe
failure but referred to the evapora-
tor probe
deactivate the high-pressure input
and, if the alarm happens during
the status "START" push the key T
10 to set the instrument for a new
cycle
push the key T 10 to set the
instrument for a new cycle
push the key T 10 to set the
instrument for a new cycle
push the key T 10 to set the
instrument for a new cycle
push the key T 10 to set the
instrument for a new cycle
push the key T 10 to set the
instrument for a new cycle
Effects
if the alarm happens during the
status "STOP" it does not permit
the start of a cycle of quick-
cooling/freezing for temperature
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, the compressor
output is deactivated
the cycle/phase of quick cooling/
freezing for temperature ends
when the time established with
the parameter "c1" or "c4" is
passed
the compressor, evaporator fans
and defrost outputs are deacti-
vated
the compressor, evaporator fans
and defrost outputs are deacti-
vated
the concerning outputs remain
activated
the compressor, evaporator fans
and defrost outputs are deacti-
vated
