cut-off; see parameters A10 and A12
-
press a key to restore normal display
Main consequences:
-
if the interruption lasts longer than the time
established with parameter A10, the device
will store the alarm

that parameter u1 and/or parameter u11 is
set at 3)
iA

switch off and re-start the device or suspend
the power supply
Main consequences:

that parameter u1 and/or parameter u11 is
set at 3)
COH
Condenser overheated alarm.
Solutions:

that parameter u1 and/or parameter u11 is
set at 3)

the condenser fan will be on (only if parameter
u1 and/or parameter u11 is set at 6)
CSd
Compressor shut down alarm.
Solutions:
-
check the condenser temperature; see pa-
rameter C7
-
switch the device off and back on again: if
when the device is switched back on, the
temperature of the condenser is still higher
than that established in parameter C7, dis-
connect the power supply and clean the con-
denser
Main consequences:
-
the compressor and the evaporator fan will be
switched off
-
the alarm output will be activated (provided
that parameter u1 and/or parameter u11 is
set at 3)
-
the condenser fan will be on (only if parameter

dFd
Defrosting alarm switched off because maximum
time has been reached
Solutions:
-
heck the integrity of the evaporator probe;
see parameters d2, d3 and d11
-
press a key to restore normal display
Main consequences:
-
the device will continue to operate normally.
When the cause of the alarm disappears, the device restores
normal operation, except for the following alarms:
-
the power supply interruption alarm (code “
PF
”) which
requires the pressing of a key
-
pressure switch alarm (code “
iSd
”) which requires the
switching off of the device or the temporary suspension
of the power supply
-
compressor blocked by condenser temperature alarm
(code “
CSd
”) which requires the switching off of the
device or the temporary suspension of the power sup-
ply

has been reached (code “
dFd
”) which requires the
pressing of a key.

ERRORS
12.1
Errors
Code Part

check that the probe is the PTC or NTC or
Pt 1000 type; see parameter P0
-
check the device-probe connection
-
check the cabinet temperature or the CPT
temperature
Main consequences:
-
compressor activity will depend on param-
eters C4 and C5
-
the defroster will not be activated
-
the alarm output will be activated (provided
that parameter u1 and/or parameter u11 is
set at 3)
-
the door heating elements will be switched off
(only and provided parameter u1 and/or pa-
rameter u11 is set at 4)
-

will be deactivated (only if parameter u1 and/
or parameter u11 is set at 5)
-
if parameter P4 is set at 3, the temperature
associated to regulation will be that detected
by the outlet air probe
Pr2
Evaporator probe error
Solutions:
-
the same as the preceding case but with re-
spect to the evaporator probe
Main consequences:
-
if parameter P3 is set at 1, the defrosting
period will last for the amount of time set with
parameter 3
-
if parameter P3 is set at 1and parameter d8 is
set at 2 or to 3, the device will operate as if
parameter d8 were set at 0
-
if parameter F0 is set at 3 or 4, the device will
operate as if the parameter were set at 2
-
the alarm output will be activated (provided
that parameter u1 and/or parameter u11 is
set at 3)
Pr3
Condenser probe/display probe/outlet air probe
error
Solutions:
-
the same as previous case but relative to the
condenser probe/display probe/ outlet air
probe
Main consequences:
-
condenser overheated alarm (code “
COH
”)
will not be activated
-
the compressor blocked alarm (“
CSd
” code)
will never be activated
-
the alarm output will be activated (provided
that parameter u1 and/or parameter u11 is
set at 3)
-
the condenser fan will operate parallel to the
compressor (only if parameter u1 and/or pa-
rameter u11 is set at 6)
-
if parameter P4 is set at 3, the temperature
associated to regulation will be that detected
by the inlet air probe
rtc
Clock error
Solutions:
-
set the date, time and day of the week
Main consequences:
-
if parameter d8 is set at 4, the device will
operate as if it were set at 0.
-
the “HACCP” function will not provide infor-
mation regarding the date and hour in which
the alarm was signalled
-
he Energy Saving in real time function will not
be activated in real time
-
the alarm output will be activated (provided
that parameter u1 and/or parameter u11 is
set at 3)
ErC
User interface-control module compatibility error.
Solutions:
-
check the compatibility of the user interface
with the control module (check the data stated
on the labels)
Main consequences:
-
the control module will continue to operate
regularly.
ErL
User interface-control module communication error.
Solutions:
-
check user interface-control module control
module
Main consequences:
-
the control module will continue to operate
regularly.
When the cause of the error disappears, the device restores
normal operation, except for clock error (“
rtc
” code), which
requires the date, time and day of the week set.
