Operate as follows to exit the procedure before the operation
is complete:
10. Do not operate for 15 sec (any changes will be
saved).
It is also possible to set the tOn time through the tOn
parameter, the tOF time through the tOF parameter and the
nCY number through the nCY parameter.
It is also possible to set the time tOn via the tOn parameter.
7.1.4 Manual activation of steam injection (only if
parameter t0 is set at 0)
Operate as follows to activate steam injection in manual
mode:
1. Make sure that the device is on, that there is no
other procedure in progress and that steam
injection is allowed (see parameter P4).
2. Press and release the "STEAM INJECTION" key:
the steam injector will be switched on for the time
established with the tOn parameter or for the
entire duration the key is pressed.
7.1.5 Activation of steam injection in cyclical
mode(only if parameter t0 is set at 1)
Operate as follows to activate steam injection in cyclical mode:
1. Make sure that the device is on, that there is no
other procedure in progress and that steam
injection is allowed (see parameter P4).
2. Press and release the "STEAM INJECTION" key:
the steam injector will be switched on 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 defined
with the tOF parameter that of switch-off) or for
the entire duration that the key is pressed.
7.2 Steam generator
7.2.1 Preliminary notes
Steam generator activity depends mainly on parameter P4, as
follows:
- if parameter P4 is set at 0 or 1, pressing and
releasing the “STEAM GENERATOR” key cause the
steam generator to switch on (until the key is
pressed and released again)
- if parameter P4 is set at 2, pressing and releasing
the “STEAM GENERATOR” key will activate steam
temperature adjustment (until the key is pressed
and released again; the temperature defined with
the SPS parameter establishes the steam set-
point, that defined with the t3 parameter, the
differential and that established with the t4
parameter, that below which steam injection is
disabled).
7.2.2 Switching on the steam generator (only if
parameter P4 is set at 0 or 1)
Operate as follows to switch the steam generator on:
1. Ensure that the device is switched on and that no
other procedure is in progress.
2. Press and release the "STEAM GENERATOR" key:
the steam generator will be on (until the key is
pressed and released again).
7.2.3 Activation of steam injection temperature
adjustment (only if parameter P4 is set at 2)
Operate as follows to activate the steam temperature
adjustment:
1. Ensure that the device is switched on and that no
other procedure is in progress.
2. Press and release the "STEAM GENERATOR" key:
the steam temperature adjustment will be
activated (until the key is pressed and released
again).
