3.1.2 Settings
3.1.2.1 Assembly Related Configuration
NOTE:
The following parameters are assembly related. In or-
der to proper operation of the device, these parameter
values must match with the physical valve package.
See ND9000 Installation, Maintenance and Operating In-
structions for details.
Performance Level
Target performance level of the valve position control. Op-
tions are;
•
Aggressive; In order to optimise the control perform-
ance the device immediate response to signal changes,
overshoots
•
Over tuned; Fast response to signal changes, small
overshooting
•
Optimum; Very small overshoot with minimum step re-
sponse time
•
Stable; No overshooting, slow response to input signal
changes
•
Max stability; No overshooting, deadband may increase,
slow but stable behaviour
Positioner Fail Action
Configuration of the action taken during the LOSS OF
SUPPLY POWER (supply pressure is available). This ac-
tion will also take place when the positioner software dis-
covers a fatal device failure. In these both cases the spool
valve feeds C1 (pneumatic connector) and releases C2
pressure. Options are;
•
Undefined
•
Close
•
Open
Set value Close for double acting actuators. For single
acting actuators set value in the spring direction.
NOTE:
Perform valve calibration and tuning always when this
parameter has been changed.
Position Sensor Rotation
Defines relationship between the position sensor rotation
and valve action. Options;
•
Undefined
•
Standard : Clockwise to close
•
Nonstandard : Counter clockwise to close
Actuator Type
Actuator type indication. Options are
•
Undefined
•
Double acting actuator
•
Single acting actuator
Actuator Fail Action
Actuator fail safe position during LOSS OF SUPPLY
PRESSURE. This parameter is informational only.
•
Undefined (Double acting actuator)
•
Opening
•
Closing
Valve Type
Valve type selection. Options are
•
Linear
•
Rotary,
part-turn
•
Neles CV globe
•
Undefined
Dead Angle Compensation
The
α
0 setting is made for Metso Automation 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 effective valve opening 90° -
α
0.
Limit switches
This parameter defines either the limit switches are in-
stalled or not. Options are;
•
Not installed (default)
•
Installed
