TIME_OUT – stroke time monitoring
With this parameter you enter the monitoring time until reaching
the setpoint.
When the tolerance band is exceeded, the monitoring time is
started. If the tolerance band within the predefined time is again
not reached by the new position setpoint, an alarm is triggered.
(Parameter TIME_OUT in parameter group 5 must be activated.)
NOTICE
With active shutdown function there is no alarm message.
Once the set point has been reached, the alarm is automatically
reset.
Note
The stroke time to be monitored should be 1.5 to2 × greater than
the shortest stroke time determined 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.
POS_SW1 – switching point SW1
With this parameter you can define the switching point SW1 as a
percentage of the operating range.
If the position is below or above SW1, the corresponding signal
output on the additional plug-in module is activated (see
parameter group DIG_OUT page 34).
Note
Changing the operating range also changes the positions of the
switching points with respect to the position of the valves and
fittings.
POS_SW2 – switching point SW2
With this parameter you can define the switching point SW2 as a
percentage of the operating range.
If the position is below or above SW2, the corresponding signal
output on the additional plug-in module is activated (see also
parameter group DIG_OUT page 34).
Note
Changing the operating range also changes the positions of the
switching points with respect to the position of the valves and
fittings.
