even though the corresponding switch point has been exceeded (e.g. due to
application-related malfunctions).
• Typically the overflow protection OP reacts when the selected measuring
segment has been reached (a few mm before the set OP value).
• The overflow protection OP replies immediately and without delay. The set
delay times (e.g. of a switch point directly below) have no effect on the overflow
protection OP.
• The response of the overflow protection is indicated on the display ("Full" and
indication of the current level change every second).
5.2.3 Display and switching functions
The unit displays the current level, selectable in cm or inch. 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, OUT2) that a set limit has been exceeded or that the level is
below the limit. The parameters of the switching outputs can be set.
• Hysteresis function / normally open (Fig. 5-2):
[oux] = [Hno].
• Hysteresis function / normally closed (Fig. 5-2):
[oux] = [Hnc].
First the set point [SPx] is set, then the reset point [rPx] with the requested
difference.
The hysteresis for the overfill protection OP is fixed.
• Window function / normally open (Fig. 5-3):
[oux] = [Fno].
• Window function / normally closed (Fig. 5-3):
[oux] = [Fnc].
The width of the window can be set by means of the difference between
[FHx] and [FLx]. [FHx] = upper value, [FLx] = lower value.
