tor probe
alarm
REASONS
there is the corruption
of the configuration
data of the memory of
the instrument
• the kind of cabinet
probe you have con-
nected is not right
• the cabinet probe
plays up
• the connection in-
strument-cabinet
probe is wrong
• the cabinet tempera-
ture is outside the
limits allowed by the
working range of
the instrument
• the kind of evapora-
tor probe you have
connected is not
right
• the evaporator
probe plays up
• the connection in-
strument-evaporator
probe is wrong
• the evaporator tem-
perature is outside
the limits allowed by
the working range
of the instrument
REMEDIES
switch off the power
supply of the instru-
ment: unless the alarm
disappears, you will
have to change the
instrument
• look at the param-
eter /0
• test the integrity of
the probe
• test the instrument-
probe connection
• test the temperature
close to the probe (it
has to be between
the limits allowed by
the working range)
• look at the param-
eter /0
• test the integrity of
the probe
• test the instrument-
probe connection
• test the temperature
close to the probe (it
has to be between
the limits allowed by
the working range)
EFFECTS
• you can not gain
access the setting
procedures
• all outputs will be
forced OFF
• the compressor will
work in accordance
with the parameters
C5 and C6
• if the defrost is run-
ning, it will immedi-
ately end
• the defrost will
never be activated
• if the parameter F7
has value 3 or 4, the
evaporator fan will
work in accordance
with the compres-
sor, except what
you have set with
the parameters F4
and F5
• the defrost will end
by time (parameter
d3)
4 CONFIGURATION PARAMETERS
4.1 How to set the configuration parameters
Configuration parameters are arranged on two levels.
If you have to gain access the first level:
• press
and for 4 s : the instrument
will show
If you have to select a parameter:
• press
or
If you have to modify the value of the parameter:
• press
and or
If you have to gain access the second level:
• gain access the first level
• press
or for selecting
• press and or for setting “ -19 “
• press
and for 4 s : the instrument
will show
If you have to quit the procedure:
• press
and for 4 s or do not op-
erate for about 60 s.
5 SIGNALS
5.1 Signals
LED MEANING
Compressor LED
if it is lighted, the compressor will be ON
if it flashes, a compressor delay will be running (look at the parameters
C0, C1, C2 and C4)
Defrost LED
if it is lighted, the defrost output will be activated
if it flashes:
• a defrost delay will be running (look at the parameters C0, C1, C2 and
C4)
• the dripping will be running (look at the parameter d7)
• the freezing fluid heating will be running (look at the parameter dP)
Evaporator fan LED
if it is lighted, the evaporator fan will be ON
if it flashes, the after dripping evaporator fan delay will be running (look
at the parameter F5)
