▪ Overvoltage U>: Upper limit1
▪ Overvoltage U>>: Upper limit2
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 [V]: Absolute limit value
▪ Limit value [%]: Limit value relative to the desired voltage value (only for
devices with voltage regulation)
▪ Hysteresis limit value
▪ Delay time limit value
▪ Behavior limit value (only for devices with voltage regulation)
