6.2.2 Display and switching functions
The unit displays the current level, selectable in cm or inches� The display unit
is defined by parameter setting� The set unit of measurement and the switching
status of the outputs are indicated by LEDs�
The unit signals via two switching outputs (OUT1, OUT-OP) that a set limit has
been exceeded or that the level is below the limit� The output configuration for the
switching output OUT-OP cannot be configured (see above)� The following output
functions are available for the switching output OUT1:
• Hysteresis function / normally open (fig� 6-2):
[ou1] = [Hno]
• Hysteresis function / normally closed (fig� 6-2):
[ou1] = [Hnc]
First the switch point [SP1] is set, then the switch-off point [rP1] with the
requested difference�
• Window function / normally open (fig� 6-3):
[ou1] = [Fno]
• Window function / normally closed (fig� 6-3):
[ou1] = [Fnc]
The width of the window can be set by means of the difference between
[FH1] and [FL1]� [FH1] = upper value, FL1 = lower value

For the output OUT1 a switch-on and switch-off delay of max� 60 s can be set (e�g�
for especially long pump cycles)�
