7.5 Soft Start
To reach the setpoint the controller can follow a gradient expressed in
units (e.g. degree/ hours).
Set the increase value in parameter 62
with the desired
units/hours; only on subsequent activation the controller uses the
soft start function.
Automatic/manual tuning cannot be enabled if the Soft start is active.
7.6 Automatic/Manual Regulation for % Output Control
This function allows to select automatic functioning or manual
command of the output percentage.
With parameter 60
, you can select two methods.
1. The first selection
allows you to enable the
key with the writing
on display 1, while
display two shows
.
Press the
key to show
; it is
now possible, during the process display, to change the
output percentage using the keys
and
. To return
to automatic mode, using the same procedure, select
on display 2: the
MAN
led switches off and
functioning returns to automatic mode.
2. The second selection
enables the same
functioning, but with two important variants:
•
If there is a temporary lack of voltage or after switch-off, the
manual functioning will be maintained as well as the previously
set output percentage value.
•
If the sensor breaks during automatic functioning, the controller
moves to manual mode while maintaining the output percentage
command unchanged as generated by the PID immediately
before breakage.
