F
Compressor
protection
tripped
(hermetic
compressors
klixon).
F1
Thermal load too high in concomitance
with high ambient temperature.
F1.1
• The head and body of the
compressor are very hot;
• the compressor stops and
attempts to start after a brief
period.
Stop the machine and restore
the load within the preset
limits.
Wait a few minutes before
restarting.
F2
Thermal load too high in concomitance
with a lack of refrigerant in the circuit
(also see
A5
).
F2.1
See
F1.1
.
Get a technician to
check for leaks and eliminate
them.
Get the engineer to fill the
circuit.

G
Fuse FC1 trips.
G1
Compressor motor overloading or short
circuit, or short circuiting in the
compressor power line.
G1.1
The compressor does not
start even if the thermostat
function so requires.
Using a tester, check the motor
windings and the power cable.
Replace the compressor or
cable if necessary.
Change the fuse.
H
Fuse FF1 trips.
H1
Fan, pumps and electronic power
overload or short circuit in the power line.
H1.1
The fan and electronic board
do not work at the same
time even if there is electric
power.
Check the components and
wiring with a tester.
Replace the damaged
component or wiring.
Change the fuse.
I
The compressor
does not start
(signalled by
compressor LED
flashing)
J
Compressor delay on
K
The compressor does not start
Verify parameters OdS, AC.
L
The
temperature is
over the set
limit but there is
no alarm
message and
the buzzer, if
present, does
not sound
L1
Alarm delay on
L1.1
The temperature measured
by the probe is higher than
the set limit
Verify parameters ALd, dAO.
M
Low
temperature
alarm
M1
The alarm delay is too short or the alarm
threshold too low
M1.1
“LA” low temperature alarm
displayed (See
7.6 “Storage
temperature alarm”
)
Verify parameters ALL.
N
High
temperature
alarm
N1
The alarm delay is too short or the alarm
threshold too low
N1.1
“HA” high temperature alarm
displayed (See
7.6 “Storage
temperature alarm”
)
Verify parameters ALU.
O
After modifying
a parameter the
electronic
control
continues to
operate with the
old values
O1
The instrument has not updated the old
value or the parameter programming
procedure was not concluded correctly,
that is by pressing
O1.1
After modifying a parameter
the electronic control
continues to operate with the
old values
Turn the instrument off and on
again or re-program the
parameters correctly
