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).
