Cause : Line supply undervoltage comes when the filtered (steady-state) value of line supply voltage is lower than the alarm threshold (p0282).
- Alarm condition: Vrms < p0282 * 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 (p0282).
