5.5.6 Valve rotation direction,
ROT
The application-specific parameter
ROT
defines the rela-
tionship between position sensor rotation and valve action.
❑
Once
ROT
is displayed press the
?
key to enter
the edit state and
ROT
starts to blink.
❑
Now you may select between two values by
pressing the
+
or
-
key. The value
cC
indicates
clockwise rotation for closing the valve and
ccC
means counterclockwise to close.
❑
After the desired value is displayed, press the
key
?
to conclude the operation.
5.5.7 Valve dead angle,
A0
The
α
0
setting is made for Metso segment and ball valves.
This setting takes into account the "dead angle"
α
0
of the
ball valves. The entire signal range is then used for effec-
tive valve opening 90° -
α
0
. Use 0 % as the "dead angle"
for the valves not mentioned in Table 5.
❑
After selecting
A0
on the display, press the
?
key to enter the edit state and
A0
starts to blink.
The value currently selected appears as a per-
centage (
%
) on the display.
❑
Modify the parameter value by pressing
+
or
-
keys alternately until the desired value appears
on the display.
❑
Press the
?
key to make your selection and

5.5.10Low limit, high cutoff, high limit
ND9100P supports signal cutoff and limiting in both
ends of the operating range. The configuration parame-
ters are; low cutoff, low limit, high cutoff and high limit.
❑
If the input signal is smaller than low cutoff,
the valve will be fully closed.
❑
If the input signal is smaller than low limit,
the valve stays in the low limit.
❑
If the input signal is greater than high cutoff,
the valve will be fully opened.
NOTE:
Perform valve calibration and tuning always when con-
troller fail action parameter has been changed.
NOTE:
Perform valve calibration and tuning always when
ROT
has been changed.
