4 Technical Description
Display and reset of limit values
Parameters: 910 ... 914
Parameters: 914 ... 917
Off:
Acknowledged:
Enabled:
The current state of the limit values and resetting them takes place using the display in
the Limit Values group.
The parameters Limit Value 1, Limit Value 2, Limit Value 3 and Limit Value 4 indicate
the current settings and state of the limit values. 0 = off, 1 = enabled, 2 =
acknowledged, 3 = deactivated. The "Deactivated" state is displayed if the LV has not
been parameterised or if it has been deactivated via the digital inputs or an operating
mode (param.967). "Off" indicates either that the limit value in question is not being
used, or the monitored reference value is within the limits of Min. LV and Max. LV. If
"enabled" is displayed for a limit value, the monitored reference value is or was
outside the limits of Min. LV and Max. LV.
The parameters Reset LV 1, Reset LV 2, Reset LV 3 and Reset LV 4 enable the limit
value output to be reset if Manual or Acknowledge has been selected as the Reset
mode. To reset a limit value, you must enter "Reset" in the respective parameter. In
Manual reset mode, however, a reset is only possible if the monitored reference
value is within the limits of Min. LV and Max. LV.
This indicates either that the limit value in question is not being used, or the
monitored reference value is within the limits of Min. LV and Max. LV.
If "acknowledged" is displayed for a limit value, the monitored reference value is
outside the Good range and the exceeding of the limit value has already been
acknowledged.
If "enabled" is displayed for a limit value, the monitored reference value is outside the
limits of Min. LV and Max. LV.
