The
SIF
parameter can be used to establish whether, when the
“Slt” time expires, the injection output switches off even if the
key is still pressed down (SIF = OFF, pulse function) and
therefore one must release the key and then press it in order to
obtain a new injection, or if the output remains in any case
activated until the key is released (SIF = On, permanent
function).
The injection command is also subordinate to a block time
between two subsequent steam injections so that the steamer
can return to its temperature.
When the injection output is switched off, the time counter set
under the
“Sld”
parameter starts, during which injection
commands are not performed.
The steam injection can also be obtained automatically using
the
”SIc”, “SIi”
and
“SIt”
parameters.
The “SIi” > 0 and “SIt” >0 parameters enable automatic
injection.
The “SIc” = 0 parameter establishes the continuous automatic
cycle whereas > 0 establishes the automatic injection cycle
time.
One can therefore obtain:
1) Manual steam injection once only when one presses the INJ
key (“SIi” = 0, “Slc”=0).
2) Continuous automatic steam injection with injection time =
“SIt” and pause = “SIi” starting from when the key is pressed.
The injection cycle only terminates when one presses the INJ
key or when the steamer or the instrument itself is switched off.
3) A cycle of automatic steam injections for the time “SIc” with
injection time = “SIt” and pause = “SIi”, starting from when the
key is pressed.
At the end of “SIc” time (or if the INJ. key is pressed again
before the end of the time or if the steamer or the instrument is
switched off) the cycle of injections terminates.
In order to indicate all the possible conditions, the STEAM INJ
led operates as follows:
- OFF : injection not active
- ON : injection in progress
- Flashing: automatic injection in progress in the pause status
(“SIi” time)
4.6 – EXTRACTOR CONTROL
When the instrument is in the ON status, the EXTR. Key can
be used to enable/disable the EXTR. output.
Output activation is therefore indicated by the EXTR. led.
The extractor is normally intended as the oven’s suction fan,
however the user could command any other function (revolving
plate, second light, etc.).
If the controller is switched off (or in the event of a blackout),
when it is switched back on again, the output reverts to the
status in which it was left.
All the extractor parameters are contained in the
“
]
ES”
group.
The
“ESd”
parameter can be used to decide whether the
output is commanded by means of the key (=OFF) only or
whether the output must be also be switched off when steam
injection occurs, in order
to prevent the steam injected being extracted (=On).
In this case, the output (if on) switches off when steam
injection starts and remains switched off for the entire duration
of injection and even after it finishes for a certain time (in sec.)
that can be set under the
“Edt”
parameter.
Moreover, using the
“EAS”
= On parameter, it is possible for
the extractor output to be activated (if it is not already)
automatically, when cooking is terminated, otherwise it will only
be commanded manually (=OFF)
In order to facilitate the command of the single extractor on an
oven where there are a number or appliances, a relay switch-
type operation mode is provided, by which it is possible to
command a single extractor from any one of the instruments
installed.
In order to obtain this operation, the
“Ec
n” parameter can be
used to establish the operation of the EXTR output in relation
to the key as bistable (=OFF) or as monostable (= On).
Therefore, if one wishes to command a single extractor from
more than one instrument, it is possible to do so:
-by connecting the relay output EXTR of the first instrument so
that it commands the extractor,
-by programming the first instrument with “ECn”=OFF and all
the others =On,
-by connecting the EXTR relay outputs of all the others in
parallel and therefore to a digital input of the first one, which
must have programmed the operation = 2 (see digital input
operation).
4.7 – AUXILIARY OUTPUT AND AUXILIARY REGULATOR
(AUX)
The instrument can also be fitted with a settable auxiliary
output (AUX).
All the AUX output control parameters are contained in the
“
]
AO”
group.
The
“AOF”
parameter can therefore be used to set the output
function mode as follows:
= 0 – no function
= 1 - output ON: the output switches on/off in correspondence
with the switching on/off of the instrument.
= 2 – Auxiliary temperature regulator: the use of the AUX probe
is essential for this function.
The regulator operates according to the measurement of the
auxiliary probe, the auxiliary regulator set
“SP
A”, the relative
differential
“HA
S” and function mode
“ArF”
(Heat = H;
Cool=C).
The auxiliary regulator can be used for many applications such
as temperature controls in other areas of the oven or inside the
product.
= 3 – End of cooking signal: the output is enabled when
cooking ends and, if desired, also ahead of the time that can
be set under the
“AOt”
parameter. If the parameter is = 0 it
obviously activates exactly at the end of cooking.
The function can be used to command an external end of
cooking signal or to command various devices, such as, for
example, the actuators that open the oven’s unloading
hatches.
Once the output has been activated, it can be deactivated by
pressing the AUX (DOWN) key.
= 4 – Activation using the AUX(DOWN) key or digital input: the
output is activated by pressing the DOWN/AUX key (or by
activating a suitably programmed digital input).
