3.10.5
DANG_DN – Dead Angle Close
Use this parameter to cut o
ff
the unusable range of the valve
fl
ow characteristic curve from th e point of view of control.
The
Dead Angle Close
is a percentage of the operating range
to which the valve is moved if the input signal is 4.16 mA.
3.10.6
DANG_UP – Dead Angle Open
Use this parameter to cut o
ff
the unusable range of the valve
fl
ow characteristic curve from th e point of view of control.
The
Dead Angle Open
is a percentage of the operating range
to which the valve is moved if the input signal is 19.84 mA.
3.10.7
BOLT_POS – Actuator position
The installation type of the actuator bolt for the potentiometer
has a decisive in
fl
uence on the linearization of the
potentiometer signal.
Using the function BOLT_POS, this installation type is taken
into account in the algorithm. The following options can be
selected:
— STEM (actuator bolt on the valve spindle)
— LEVER (actuator bolt on the potentiometer lever)
For detailed information about the position of the actuator
bolt, see the operat ing instructions.
3.10.8
EXIT – Return to operating level
With this parameter you can leave the con
fi
guration level. The
positioner returns to the operating level. Here you can either
save data in the non-volatile me mory or discard all previously
made changes (also the changes in other parameter groups).
To leave the con
fi
guration level (with or without saving), press
and hold
ENTER
until the countdown from 3 to 0 is
fi
nished.
The active saving process is indicated by the message
NV_SAVE
. After saving a plausibility check is executed.
If an error occurs during the check or while saving, the data
cannot be saved and an error message is displayed instead
(see Chapter "Error codes" on page 33).
Selection
NV_SAVE
Saves settings in the non-volatile memory.
CANCEL
Discards all changes made since the last
permanent save operation.
