If the measured value is higher than the upper limit (> or >>) or lower than
the lower limit (< or <<), the device transmits an event message.

You can set the following parameters for each limit value:
▪ Relative/absolute limit value
▪ Limit value [A] or [kA]: Absolute limit value
▪ Limit value [%]: Limit value relative to the rated current of current trans-
former. With current measurements via the analog input, the value is rela-
tive to the maximum value of the analog input (e.g. 100% = 20mA).
▪ Hysteresis limit value
▪ Delay time limit value
▪ Behavior limit value (only for devices with voltage regulation)
