First the set point (SP1) is set, then the reset point (rP1) with the requested difference.
The hysteresis for the overflow prevention OP is fixed.
• Window function / normally open: [ou1] = [Fno].
• Window function / normally closed: [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.

4.9 Offset for indicating the real level in the tank
The zone between tank bottom and lower edge of the probe can be entered as offset value [OFS]. So
display and switch points refer to the actual level (point of reference = tank bottom).
For [OFS] = [0]: The reference point is the lower edge of the measuring probe.
The set offset only refers to the display on the unit. It has no effect on the analogue output and
the process value transmitted via IO-Link. The OFS parameter, however, is correctly transmitted
via IO-Link and can therefore be taken into account.
4.10 Defined state in case of a fault
In case of a fault, a state can be defined for each output. If a fault is detected or if the signal quality is
below a minimum value, the outputs pass into a defined state. For this case the response of the
outputs can be set via the parameters [FOU1] / [FOU2].
4.11 Extreme value memory
The minimum and maximum values of the temperatures occurred since the last memory reset can be
retrieved via the menu items [Lo.T] and [Hi.T].
