5.3.2 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.
• If the overflow prevention OP is activated, an adjustment to the installation
situation has to be made [cOP]. Otherwise, the unit is not ready for operation;
[
] is displayed until readiness
.
• The overflow prevention OP can be deactivated ([OP] = [OFF]).
Deactivating the overflow prevention OP 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 points [SPx] / [FHx] are always below [OP].
• The overflow prevention 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 replies 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 is only indicated on the display ([Full]
and indication of the current level change every second).
5.3.3 Display and switching functions
The device displays the current level / the current temperature, optionally in
cm / inches or °C / °F. The display unit is defined by programming. The set unit of
measurement and the switching status of the switching outputs are indicated by
LEDs.
The displayed process value (level / temperature) can be changed temporarily in
the operating mode.
