3.6.9 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.
3.7 Parameter group 3: Operating range
3.7.1 MIN_RGE – Operating range min.
The working range can be con
fi gured to be smaller than the
maximum mechanical working range.
The setpoint range always refer s to the con
fi gured working
range. Use this parameter to specify the lower limit of the
operating range.
CAUTION
This function is only active in control mode.
In the event of a power supply fa ilure (electric or pneumatic),
and in manual mode, the mechanical end positions are
approached.
— Do not reach into the adjustment mechanism.
NOTE
The operating range must be greater than 10% of the sensor
range.
NOTE
The display of the positioner in operating modes 1.0 through
1.2 always refers to the co n
fi gured working range and
indicates the position in %.
3.7.2 MAX_RGE – Operating range max.
The working range can be con
fi gured to be smaller than the
maximum mechanical working range.
The setpoint range always refer s to the con
fi gured working
range. Use this parameter to specify the upper limit of the
working range.
CAUTION
This function is only active in control mode.
In the event of a power supply fa ilure (electric or pneumatic),
and in manual mode, the mechanical end positions are
approached.
— Do not reach into the adjustment mechanism.
NOTE
The operating range must be greater than 10% of the sensor
range.
NOTE
The display of the positioner in operating modes 1.0 through
1.2 always refers to the co n
fi gured working range and
indicates the position in %.
