Cause : Line supply overvoltage comes when the filtered (steady-state) value of the rms line supply voltage Vrms is higher than the alarm threshold (p0281).
Alarm condition: Vrms > p0281 * p0210.
Alarm value (r2124, floating point): Actual steady-state line supply voltage.
- check the line supply.
- check the line supply voltage (p0210).
- check the alarm threshold (p0281).
