At power up the device starts as configured at “St.Fn” [C.G06]
configuration parameter.

NOTES:
1) When auto/manual control mode is selected by logic input, at

power up the instrument will start in accordance with the logic
input status.
If the logic input status requires the manual mode, the
instrument will verify the “St.Fn” [C.G06] parameter setting
and if it is equal to "Auto", "ñan" or “Cnd.A” the power output
will be set to zero otherwise the power output will be set equal
to the last value prior to power shut down.

2) If the instrument is configured for one control output, the

control output is a servomotor type (close or open loop) and
device starts up in manual mode, the following action may
occur:
2.A) The valve remains in the same position if:

“St.Fn” [C.G06] = “ñan” or
“St.Fn” [C.G06] = “Cnd.A” or
“St.Fn” [C.G06] = “Cnd.b” and “Añ.UL” [C.G04] = “buñ.”

2.B) The valve will be moved to the value set in “Añ.UL” if

“St.Fn” [C.G06] = “Cnd.b” and “Añ.UL” [C.G04] is
different from “buñ.”

DIRECT ACCESS TO THE SET POINT
During the “Normal Display Mode” when the device is in
controller mode or in stand-by mode, it is possible to access
directly to the set point modification.
Pushing

s or t for more than 2 s, the set point will begin

changing.
The new set point value becomes operative since no push-
button has been depressed at the end of 2 s time out.
The direct access to the set point is disabled if the run time
group 2 is software protected.
