3.7.3 ZERO_POS – Zero position
With this parameter you can assign the zero position of the
display to the zero position of the valves and
fi ttings. It also
allows you to select the direction of rotation of the sensor
shaft (looking at the open housing).
NOTE
Normally, the zero position is determined automatically and
saved during standard Autoadjust.
Linear actuators
Î
“counterclockwise ”
Rotary actuators Î “clockwise”
Selection
CLOCKW Limit stop reached turning clockwise
CTCLOCKW Limit stop reached turning counterclockwise
3.7.4 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.
3.8 Parameter group 4: Messages
3.8.1 TIME_OUT – Dead band time limit
With this parameter you enter the monitoring time until
reaching the setpoint.
When the tolerance band is exceed ed, the monitoring time is
started. If the tolerance band within the prede
fi ned time is
again not reached by the new po sition setpoint, an alarm is
triggered.
(Parameter
TIME_OUT in parameter group 5 must be
activated.)
CAUTION
With active shutdown function there is no alarm message.
Once the setpoint has been reached, the alarm is
automatically reset.
NOTE
The stroke time to be monitored should be 1.5 to 2x greater
than the shortest stroke time selected during automatic
adjustment.
Press and hold the
ENTER button to display the stroke time.
Press ENTER again to toggle between UP stroke time and
DOWN stroke time.
3.8.2 POS_SW1 – Switching point SW1
With this parameter you can de fi ne the switching point SW1 as
a percentage of the operating range.
If the position is above or below SW1, the corresponding
signal output on the plug-in module is activated (see also
parameter group
DIG_OUT on page 29).
NOTE
Changing the operating range also changes the positions of
the switching points with respect to the position of the valves
and
fi ttings.
