In this case, set a new datum or retract.
If all sorting indicators light up, this means that the upper sorting limit is less
than the lower limit.

EXT D-sub connection is active.
Display Freeze by Measured Value Output Signal
The effect of the signal for measured value output on the display is defined in user
parameter P23.
➤ Concurrent display: No display freeze. The unit shows the current measured
value ( ).
➤ Frozen display: The display is frozen and is updated with each signal for meas-
ured value output ( ).
➤ Frozen/concurrent display: The display freezes only as long as the signal is
present ( ).
