Door micro switch input alarm (HACCP alarms)
Solutions:
-
check the causes of the activation of the in-
put; see parameters i0, i1, i5 and i6
Main consequences:
-
the effect established with the parameters i0
and i5
-
if parameter is set at 1, the device will store
the alarm, provided parameter i2 is not set at
-1
-
the alarm output will be activated (provided
that parameter u1 and/or parameter u11 is
set at 3)
iA
Multifunction input alarm
Solutions:
-
check the causes of the activation of the in-
put; see parameters i0, i1, i5 and i6
Main consequences:
-
the effect established with the parameters i0
and i5
-
the alarm output will be activated (provided
that parameter u1 and/or parameter u11 is
set at 3)
iSd
Pressure switch alarm
Solutions:
-
check the causes of the activation of the
input; see parameters i0, i1, i5, i6, i7, i8
and i9
-
switch off and re-start the device or suspend
the power supply
Main consequences:
-
the regulators will switch off
-
the alarm output will be activated (provided
that parameter u1 and/or parameter u11 is
set at 3)
COH
Condenser overheated alarm.
Solutions:
-
check the condenser temperature; see pa-
rameter C6
Main consequences:
-
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
u1 and/or parameter u11 is set at 6)
CSd
Condenser overheated 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
u1 and/or parameter u11 is set at 6)
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:
-
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 supply
-
Defrosting alarm switched off because maximum time
has been reached (code “
dFd
”) which requires the
pressing of a key.

ERRORS
12.1
Errors
Code Part
Pr1

Solutions:
-
check that the probe is the PTC or NTC type;
see parameter P0
-
-
check the device-probe connection
-
check the cell temperature
Main consequences:

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 resistors will be switched off (only
and provided parameter u1 and/or parameter
u11 is set at 4)
-
the neutral area operating resistors will be
deactivated (only if parameter u1 and/or pa-
rameter u11 is set at 5)
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 error.
Solutions:
-
the same as the preceding case but with re-
spect to the condenser 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
parameter u11 is set at 6)
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 er-
ror.
Solutions:
-
check user interface-control module control
module
Main consequences:
-
the control module will continue to operate
regularly.
When the problem that caused the alarm disappears, the
device is restored to normal operation.
