P30 Over Voltage Level PFN 07
LCD Display
PFN:Over Vlt Lvl
07 Off
Range OFF, 1 – 40 % (Default OFF)
Description If the MX detects for one cycle of any of the individual input phase voltages (rms) is above the over
voltage level, the over/under voltage alarm is shown and the voltage trip timer begins counting. The
delay time must expire before the starter faults. The over voltage condition and the phase on which
occurred is displayed.
NOTE: For the over voltage protection to operate correctly, the Rated Voltage parameter must be set
correctly.
NOTE: The voltage level is only checked when the starter is running.

P31 Under Voltage Level PFN 08
LCD Display
PFN:Undr Vlt Lvl
08 Off
Range OFF, 1 – 40 % (Default OFF)
Description If the MX detects for one cycle of any of the individual input phase voltages (rms) is below the under
voltage level, the over/under voltage alarm is shown and the voltage trip timer begins counting. The
delay time must expire before the starter faults. The under voltage condition and the phase on which
it occurred is displayed.
NOTE: For the under voltage protection to operate correctly, the Rated Voltage parameter must be
set correctly.
NOTE: The voltage level is only checked when the starter is running.
