13.4.3 Deningthedirectionofthetravelsensor
Pot Dir:
The direction of the actual value potentiometer can b
e dened.
Rise: For valves with rising direction of action
ܟ Linear actuators: Valve spindle rises when valve opens
ܟ Quarter turn actuators: Viewed from above, shaft turns
anticlockwise when valve opens
Fall: For valves with falling direction of action
ܟ Linear actuators: Valve spindle falls when valve opens
ܟ Quarter turn actuators: Viewed from above, shaft turns
clockwise when valve opens
In combination with the respective direction of the valve, these
settings mean that the valve opens when the signal rises
and the display and output values have the same direction of
action.
If valves are operated in reverse (rising signal closes valve), the
W-Direction parameter must be reset, otherwise the display
and the output signal would be inversed.
13.4.4 Deningtheactualvalueoutputsignal
If a higher value is entered for OutMinPos than for
OutMaxPos, the direction of the output signal is
inverted.
OutMinPos:
Denes the valve position at which an actual value signal of
4 mA is emitted at the output.
OutMaxPos:
Denes the valve position at which an actual value signal of
20 mA is emitted at the output.
13.4.5 Determining switch points for error monitoring
I Min W:
Denes the point below which the set value signal activates an
error message
I Max W:
Denes the point above which the set value signal activates an
error message.
I Min X:
Denes the point below which the actual value signal activates
an error message.
I Max X:
Denes the point above which the actual value signal activates
an error message.
13.4.6 Scalingtheactualvalueandsetvaluedisplay
Scaling:
Submenu for scaling the actual value and set value display.
Scaling:
Denes whether the actual and set value display is to be
displayed as scaled variable or in percent.
ON:display as scaled variable; OFF: display in percent
Decimalpoint:
Determines the number of digits displayed after the decimal
point.
4 mA
:
Denes the value which is displayed when there is a 0/4mA
signal.
20 mA :
Denes the value which is displayed when there is a 20mA
signal.
