Input signal
Channel 1 has a special task; it is used as the reference curve for the other channels in the group. All
other channels in the group can be compared with channel 1 independently of one another. If the con-
figured tolerance band is exited, an alarm occurs, and an alarm text is displayed in the "status and title
line" and entered in the alarm list and event list.
NOTE!
The tolerance band comparison is only possible within the scaling limits. If a channel drops below or ex-
ceeds the range, this will result in both a min. and a max. alarm as with all other functions (in this case,
pos. tolerance and neg. tolerance).
Upper switching
differential Only available for channel 1 of a group.
-100 to
-2 to 0 If there is a positive tolerance violation,
the current measured value from chan-
nel 2 to 6 must first drop below the cur-
rent measured value of channel 1, plus
the upper tolerance band limit and upper
switching differential, in order for the
alarm to be canceled.
Lower switching
differential Only available for channel 1 of a group.
0 to
2 to 100 If there is a negative tolerance violation,
the current measured values from chan-
nel 2 to 6 must first exceed the current
measured value of channel 1, plus the
lower tolerance band limit and lower
switching differential, in order for the
alarm to be canceled.
Alarm text upper
limit Available as from channel 2 of a group.
Use default text or enter other text.
The text entered (max. 31 characters) is
displayed and entered in the alarm and
event list if the selected channel exits the
tolerance in positive direction.
Alarm text lower
limit Available as from channel 2 of a group.
Use default text or enter other text.
The text entered (max. 31 characters) is
displayed and entered in the alarm and
event list if the selected channel exits the
tolerance in negative direction.
Show auxiliary
line 1, 2 Two auxiliary lines (level lines) can be shown for each channel.
No , Yes If "Yes" is selected, the auxiliary line is
shown in the vertical and horizontal
curve diagram if this has been activated
generally in the configuration of the dia-
gram view.
Auxiliary line val-
ue 1, 2 The two auxiliary lines can be used, for example, to define a lower and upper limit.
As a result, the user can see in the diagram whether the current value is within the
defined range.
0 to 100 Auxiliary line value
Auxiliary line col-
or 1, 2 The default setting for the auxiliary line color corresponds to the color of the analog
channel concerned (Configuration > Display > Colors).
Use default color or select another color. Auxiliary line color
