6.5.3 Menu explanations
Level Designation Selection/input
options Explanation
1.1.1 OUTPUT B1 INACTIVE
LEV.VALUE B1 Level value switching point. A numeric value between 0.0 ...
100% of the level value can be set. If the current level value
exceeds this set switching point, then output B1 is
activated.
Note Note Note Note
The function NC or NO can be selected using menu 3.3.
1.1.2 OUTPUT B1 HYST.B1 Hysteresis setting for the level value switching point. Value
range 0…switching point. Example: If, under 1.1.1, a
switching point of 200 is set, a hysteresis value of 0...200
can be set. If a value of 0 is entered, this output has no
hysteresis. If a value of 20 is entered, the output works as
follows: If the current level value exceeds the value of 200,
the output switches. 3 If the current level value is under
the hysteresis value of 180, the switching output returns to
its normal state. 4
Note Note Note Note
If this function is inverted, the output under menu 3.3 must
be set from NO 1 to NC 2 or vice versa. This function is
not activated with the counter switching point.
1.2.1 OUTPUT B2 INACTIVE
LEV.VALUE B2 See LEV.VALUE B1
1.2.2 OUTPUT B2 HYST.B2 See HYST. B1
1.3 DISPLAY LEVEL

LEVEL & %
1.4 TIME CONST. Setting : 1 ... 20 seconds
Note Note Note Note
The settable time constant affects the current output and
the displayed current level. It thus allows attenuated
depiction when the display is not calm. If the current level
is polled via HART communication, then the transferred
measured value is dependent on the time constant.
