CODE

data
alarm
top probe
alarm
REASONS
there is a corruption of
the configuration data
in the memory of the
instrument
• the kind of top probe
you have connected
is not right
• the top probe plays
up
• the connection in-
strument-top probe
is wrong
• the top temperature
is outside the limits
allowed by the work-
ing range of the in-
strument
REMEDIES
turn OFF the power
supply of the instru-
ment: unless the alarm
disappears, you will
have to change the in-
strument
• look at parameter /0
• test the integrity of
the probe
• test connection in-
strument-probe
• test the temperature
close to the probe
EFFECTS
• the access to the set-
ting procedures will
not be allowed
• all outputs will be
turned OFF
the top output will be
turned OFF
The indications showed by the instrument flashes, except the indications “AL1“ and
“AL2“ (they are alternated with the top or the floor temperature) and the buzzer utters
an intermittent beep.

TECHNICAL DATA
9.1 Technical data
Box: self-extinguishing grey.
Size: 72 x 144 x 79 mm (2.83 x 5.66 x 3.11 in).
Installation: panel mounting, panel cut out 67 x 138 mm (2.63 x 5.43 in), with screw
brackets (supplied by the builder).
Frontal protection: IP 54.
Connections: extractable terminal blocks with pitch 7.5 mm (0.29 in) for cables up to
2.5 mm² (0.38 sq in, power supply and outputs) and with pitch 5 mm (0.19 in) for
LED minute
if it is lit, the unit of measure of the time showed by the instrument will
be minute
LED timer
if it flashes, the count of the timer for delayed starting (or the count of
the cooking timer) will be running
LED ON STAND-BY
if it is lit, the instrument will be in the STAND-BY mode (turned OFF)
MEANING
the instrument has finished counting the cooking timer

• the kind of floor
probe you have con-
nected is not right
• the floor probe plays
up
• the connection in-
strument-floor probe
is wrong
• the floor tempera-
ture is outside the
limits allowed by the
working range of
