7.6.3 Monitoring functions
By means of monitoring functions the user can define an extended condition monitoring, e.g. for triggering
an over-current alarm, if one of the phase currents exceeds a certain limit value.
The states of all monitoring functions
…will be shown in the alarm list (“Events” via main menu)
…build a summary alarm state
Logic inputs
Up to three states of limit values, failure-current monitoring, logic inputs or other monitoring functions.
Unused inputs will automatically be initialized in a way that they do not influence the output.
Logic function
For the logical combination of the inputs the function AND, NAND, OR, NOR, DIRECT and INVERT are
available. These logical functions are described in
Appendix C
.
Delay time on
The time a condition must be present until it is forwarded
Delay time off
Time to be waited until a condition, which is no longer present, will be released again
Description
This text will be used for visualization in the alarm list
List entry (with data logger only)
•
Alarm / event
: Each state transition will be recorded in the appropriate list
•
none:
No recording of state transitions
Possible follow-up actions
•
Driving a logic output. The assignment of the monitoring function to a digital output / relay is done via
the settings of the corresponding output.
•
Visualization of the present state in the alarm list
•
Combining the states of all monitoring functions to create a summary alarm
•
Recording of state transitions as alarm or event in the appropriate lists
