Variation (
S.S.cY.
):
Selecting
S.S.cY.
(Soft Start Cycle) the controller will operate as per the fi rst
selection (
Pr.cy
) but with two important variations. If at starting the process
is lower than SET1, the device regulates the output power according to the
percentage selected on parameter 62
GrAd
.
When the process is greater than SET1 or the time selected on parameter 63
MA.ti.
is elapsed, it reaches maximum power up to SET2. When the process
reaches SET2 the controller keeps it to infi nity.
If on parameter 59
oP.Mo.
is set
S.S.cY.
it is possible to select
HidE
on
parameter 17
c. S.P.
: SET1 is no longer displayed and SET2 label becomes SET.
Starting the manual tune during the regulation on SET1, TUN led switches ON
only when the regulation pass to SET2.
The autotuning (manual or automatic) works only if SET2 is being regulated.
If the autotuning is launched during regulation on SET1 it doesn’t start until
the regulation pass to SET2.
