7 MANAGEMENT OF UTILITIES
7.1 Steam injection
7.1.1 Preliminary notes
The steam injection activation mode depends on parameter t0,
as follows:
- if the parameter t0 è is set at 0, pressing and
releasing the “STEAM INJECTION” key will cause
the injection of steam for the time established with
parameter tOn or for the entire time the key is
pressed.
- if parameter t0 is set at 1,pressing and releasing
the “STEAM INJECTION” key will activate steam
injection in cyclic mode (at maximum for the
number of cycles established with the nCY
parameter or until the key is pressed and released
again; the time defined with the tOn parameter
establishes the switch-on duration of the injector
and that established with the tOF parameter,
switch-off) or will cause steam injection for the
entire time the key is pressed.
The steam injection activation consent mode depends on
parameter P4, as follows:
- if parameter P4 is set at 0, steam injection will be
allowed if the steam generator has been switched
on.
- if parameter P4 is set at 1, steam injection will be
allowed if the steam generator is on and the multi-
function input has been activated (until the input
has been deactivated and on condition that the
parameter i5 is set at 1).
- if parameter P4 is set at 2, steam injection will be
allowed if the temperature regulation of the steam
has been activated and the steam temperature is
above that established with the SPS parameter
(until the temperature drops below that
established with parameter t4).
7.1.2 Quick setting of the time tOn (only if the
parameter t0 is set at 0)
The time unit of measurement of the time tOn is the second.
Operate as follows to set the time tOn:
1. Ensure that the device is switched on and that no
other procedure is in progress.
2. Hold the “STEAM GENERATOR” key down for 1 s:
the “T ON ” LED will flash and the bottom part of the
"LOWER" display will show the flashing tOn time
value.
3. Press and release the UP or DOWN key within 15 s
to set the value of the time tOn.
4. Press and release the "STEAM GENERATOR" key or
do not operate for 15 sec: the “T ON ” LED and the
bottom part of the "LOWER" display will remain on
and the device will exit the procedure.
Operate as follows to exit the procedure before the operation
is complete:
5. Do not operate for 15 sec (any changes will be
saved).
It is also possible to set the time tOn via the tOn parameter.
7.1.3 Quick setting of the tOn time, tOF time and
the nCY number (only if parameter t0 is set
at 1)
The time unit of measurement of the time tOn and time tOF is
the second.
Operate as follows to set the time tOn:
1. Ensure that the device is switched on and that no
other procedure is in progress.
2. Hold the “STEAM GENERATOR” key down for 1 s:
the “T ON ” LED will flash and the bottom part of the
"LOWER" display will show the flashing tOn time
value.
3. Press and release the UP or DOWN key within 15 s
to set the value of the time tOn.
Operate as follows to set the time tOf:
4. Press and release the “STEAM GENERATOR” key
during setting of the time tOn: the “T ON ” LED will
switch off, the “T OFF ” LED will flash and the
bottom part of the "LOWER" display will show the
flashing tOF time value.
5. Press and release the UP or DOWN key within 15 s
to set the value of the time tOF.
Operate as follows to set the number nCY:
6. Make sure that parameter t6 is set at 1.
7. Press and release the “STEAM GENERATOR” key
during setting of the time tOF: the “T OFF ” LED will
switch off, the “CYCLES LED will flash and the
bottom part of the "LOWER" display will show the
flashing nCY number value.
8. Press and release the UP or DOWN key within 15 s
to set the value of the number nCY.
9. Press and release the "STEAM GENERATOR" key or
do not operate for 15 sec: the “CYCLES” LED and
the bottom part of the "LOWER" display will
remain on and the device will exit the procedure.
