Limit Value Groups

In SICAM P, you can parameterize up to 7 limit value groups. For limit value group 7, only volt-
ages are allowed.
Every limit value group provides the option to monitor whether the measurements exceed (>)
or fall short of (<) a measured value that is entered. In each of the seven limit value groups, up
to six measured quantities (no power quantities) can be ANDed or ORed.
The limit value groups set can be allocated either to binary outputs or to the internal counters.
The oscilloscope can be triggered using a limit value group 1 to 6.
•
Filter time: Time for which a threshold breach must remain in order to trigger an alarm. Input
from 0.0 s to 9.9 s.
Note
To make sure that limit violations will be registered, enter a filter time ≥ 1 s.
•
Hysteresis: Entry from 0.1 % to max. 10 %. The value relates to the nominal values for the
individual measured values.
Note
If the device provides additional analog inputs (optional), you can use external measurement sig-
nals for limit-value monitoring.
Note
Limit value group 7 allows you to monitor the measured voltages in real time and logs the mea-
sured value that caused a limit violation.
