2.21.6 Set Points (Measured Values)
To recognize extraordinary operational conditions, warning levels can be pro-
grammed. When exceeding (with cos ϕ: undershooting) a programmed limit value a
message is generated that can be allocated to both output relays and LEDs. In con-
trast to the actual protection functions the monitoring function operates in the back-
ground; therefore it may not pick up if measured values are changed spontaneously
in the event of a fault and if protection functions are picked up. Also, monitoring does
not respond immediately before a trip because an alarm is only output if the setpoint
are repeatedly violated.
