5.2.2 Notes on the integrated overflow prevention
With the parameter [OP] (OP = overflow prevention), one of the upper measuring
segments is defined as integrated overflow prevention OP.
• If the overflow prevention OP is activated, an adjustment to the installation
situation has to be made [cOP].
• The overflow prevention OP can be deactivated ([OP] = [OFF]).
Deactivating the overflow prevention can impair the operational reliability.
For optimum operation and maximum operational reliability, we therefore
recommend to not deactivate the overflow prevention OP.
• The overflow prevention OP is the maximum limit of the measuring range. The
switch point [SP1] / [FH1] is always below [OP].
• The overflow prevention OP is
not
assigned to a separate output. It offers
additional protection and only switches if as the level rises the switching
output has not switched even though the corresponding switch point has been
exceeded (e.g. due to application-related malfunctions).
• Typically the overflow prevention OP reacts when the selected measuring
segment has been reached (a few mm before the set OP value).
• The overflow prevention OP reacts immediately and without delay. The set
delay times (e.g. of a switch point directly below) have no effect on the overflow
prevention OP.
• The response of the overflow prevention OP is indicated on the display ("Full"
and indication of the current level change every second).
5.3 Display 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 switching output are indicated by LEDs.
