parameter c4

(6)

if the cooking timer is interrupted (with the procedure given in paragraph 5.4 or by activation of the malfunction input), the duration of
buzzer activation and of the acoustic output and the flashing duration of the 00:00 indication will be 3 seconds

(7)

the parameter differential is 10 °C/18 °F

(8)

the activation of the on/stand-by input causes the passage from the on state or from the programmed switch-on state to the stand-by state:
the successive deactivation always causes the passage to the on state. If the on/stand-by input is active, it will not be allowed to pass from
the stand-by state to the on state or the programmed switch-on state by pressing the keys

pressing the

key causes the associated effect.

TECHNICAL DATA

12.1 Technical data
Container: grey self-extinguishing.
Front panel protection rating: IP 54.
Connections: removable terminal boards (power supply, inputs and
outputs), 6-pole connector (serial port).
Temperature of use: from 0 to 55 °C (from 32 to 131 °F, 10 ... 90%
relative humidity without condensate).
Power supply: 115 ... 230 VAC, 50/60 Hz, 5 VA (approx) or 24 VAC,
50/60 Hz.
Keeping the clock data in a power-cut: 24 h with battery
charged.
Battery charging time: 2 min without interruptions (the battery is
charged by the instrument power supply).
Alarm buzzer: incorporated.
measurement inputs: 1 (chamber probe) for J/K thermocouple or
Pt 100 2 wire probe (according to the model).
Digital inputs: 2 inputs:

• on/stand-by input in high voltage (230 VAC) with

configurable polarity

• multifunction input, for NO/NC contact (potential-

free contact, 5 V 1 mA).

Range of measurement: from -99 to 800 °C (from -99 to 999 °F) for
J thermocouple, from -99 to 999 °C (from -99 to 999 °F) for K thermo-
couple, from -99 to 650 °C (from -99 to 999 °F) for Pt 100 probe.

DIGITAL INPUTS
polarity of the on/stand-by input (instrument off with input active) (8)
0 = live input active
1 = non-live input active
effect caused by the activation of the multifunction input
0 = no effect
1 = STAR/INTERRUPTION OF THE COOKING TIMER - the activation of the input will cause the cooking

timer to start and the successive activation will cause its interruption

2 = BUZZER, ACOUSTIC OUTPUT AND BUZZER OUTPUT DEACTIVATION - the activation of the input will

cause deactivation of the buzzer, the acoustic output and the buzzer output (activate the input again
to deactivate these utilities again)

3 = STEAM INJECTION - in this case:

• if t0 = 0, the activation of the input causes the injection of steam for the time established with

parameter t2 or for the entire duration that the key is pressed (parameter t1 establishes the minimum
time that can pass between the two successive injections) (9)

• if t0 = 1, the activation of the input will enable automatic steam injection (in cyclical mode; param-

eter t2 establishes the duration of the switch-on of the injector and parameter t1 establishes the
duration of switch-off) until the input is activated again (9)

type of contact of the multifunction input
0 = NO (input active with closed contact)
1 = NC (input active with open contact)

1 = odd
2 = even

5.4

Interrupting the cooking timer

• press

for 1s: the “timer” LED switches off and the buzzer will be
activated for 3s.

STEAM INJECTION

6.1

Preliminary considerations

The functioning mode of the steam injection depends on parameter t0.
If the parameter t0 is set at 0, pressing the

key causes the injection

of steam for the time established with parameter t2 or for the entire
duration that the key is pressed. The parameter t1 establishes the mini-
mum time that can pass between the two successive injections.
If the parameter t0 is set at 1, pressing the key

will enable the

automatic injection of the steam (in cyclical mode: parameter t2 estab-
lishes the duration of the injector switch-on and parameter t1 estab-
lishes the duration of switch-off).
Using the multifunction input, it is also possible to cause the same effect
by pressing the

key in remote mode.

If the steam injection is not managed by any digital output , pressing the

key will cause the display of the “no” indication for 1s in the lower

part of the display.
6.2

Quick setting of the parameter t2

• make sure that the instrument is in on state and that no procedure is

in progress

• press

and

: the upper part of the display will show “t2”, the
lower part the corresponding value and the LED

will flash.

The parameter t2 can be set between 1 and 250 ds.
If steam injection is not managed by any digital output, the lower part
of the display will show “no” for 1s.
• press

within 15s

• press

: the LED will switch-off, after which the instrument will
exit the procedure.

To exit the procedure in advance:
• do not operate for 15s (any modifications will be saved).

AIRHOLE

7.1

Preliminary considerations

The airhole is activated in the following conditions:
• before the conclusion of the cooking timer count (of the time established

with the parameter c5), for the time established with parameter c6

• in manual mode, by pressing the

, key for the time established

with parameter c7.

If the airhole is not managed by any digital output, pressing the
key will cause the display of the “no” indication for 1s in the lower part
of the display.
7.2

Quick setting of the parameter c7

• make sure that the instrument is in on state and that no procedure is

in progress

• press

and

: the upper part of the display will show “c7”, the
lower part the corresponding value, the left part
and the LED will flash.

The parameter c7 is visualised in the minutes:seconds format.
To modify the minutes:
• press

within 15s

• press

: the right part will flash.

To modify the seconds:
• press

within 15s.

The parameter c7 can be set between 00:00 and 60:00 min:s.
If the airhole is not managed by any digital output, the lower part of the
display will show “no” for 1s.
• press

: the LED will switch-off, after which the instrument will
exit the procedure.

To go back to previous levels:
• press

several times during the procedure.

To exit the procedure in advance:
• do not operate for 15s (any modifications will be saved).
7.3

Activation of the airhole in manual mode

• make sure that the instrument is in on state and that no procedure is

in progress

• press

: the LED will switch on and the airhole will be activated,
both for the time established with parameter c7.

7.4

Airhole deactivation

• make sure no procedure is in progress
• press

: the LED will switch-off.
