3.7. U> overvoltage stage 1
The 7th menu item shows the parameterization of U> overvoltage stage 1.
Trip: Trip - activate/deactivate the function.
Trip V: Switching point – voltage value (in percentage of the nominal
voltage) that leads to a trigger when overshot.
Hyster: Hysteresis - undershooting of the switching point minus the
hysteresis (in percentage of the nominal voltage) leads to a re-
lapse.
Delay: Trigger time - duration for which the switching point must be
overshot so that it leads to a trigger.
Return: Relapse time - duration for which the switching point must be
undershot so that it leads to a relapse.
3.8. U>> overvoltage stage 2
The 8th menu item shows the parameterization of U>> overvoltage stage 2.
Settings:
see section 3.7 U> overvoltage stage 1
3.9. U< undervoltage stage 1
The 9th menu item shows the parameterization of U< undervoltage stage 1.
Trip: Trigger - activate/deactivate the function.
Trip V: Switching point – voltage value (in percentage of the nominal
voltage) that leads to a trigger when undershot.
Hyster: Hysteresis - overshooting of the switching point plus the hyste-
resis (in percentage of the nominal voltage) leads to a relapse.
Delay: Trigger time - duration for which the switching point must be
undershot so that it leads to a trigger.
Return: Relapse time - duration for which the switching point must be
overshot so that it leads to a relapse.
3.10. U<< undervoltage stage 2
The 10th menu item shows the parameterization of U<< undervoltage
stage 2.
Settings:
see section 3.9 U< undervoltage stage 1
