trip feature but produces an alarm indication instead of a trip.
•
UNDERVOLTAGE ALARM DELAY: Enter the delay for activation of the undervoltage
alarm.
•
UNDERVOLTAGE TRIP LEVEL: If the voltage remains below this value while the motor
is running for the time specified in the
Manager 3 will trip. Set this value to "OFF" if no undervoltage trip is required.
