UNDER/OVERVOLTAGE PROTECTION
The undervoltage and overvoltage settings are available only if the
VT PRIMARY VOLTAGE
setting is not “OFF”. These setpoints are programmed as follows:
•
UNDERVOLTAGE ALARM LEVEL
: This feature functions the same as the undervoltage
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
UNDERVOLTAGE TRIP DELAY
, the MM3 Motor
Manager 3 will trip. Set this value to “OFF” if no undervoltage trip is required.
•
UNDERVOLTAGE TRIP DELAY
: Set the
UNDERVOLTAGE TRIP DELAY
long enough to
prevent nuisance trips from momentary voltage dips when the undervoltage trip
feature is used.
•
OVERVOLTAGE ALARM LEVEL
: This feature functions the same as the overvoltage trip
feature but produces an alarm indication instead of a trip.
•
OVERVOLTAGE ALARM DELAY
: Enter the delay for activation of the overvoltage alarm.
•
OVERVOLTAGE TRIP LEVEL
: If the voltage remains above this value while the motor is
running for the time specified in the
OVERVOLTAGE TRIP DELAY
, the MM3 Motor
Manager 3 will trip. Set this value to “OFF” if no overvoltage trip is required.
•
OVERVOLTAGE TRIP DELAY
: Program this setpoint large enough to prevent nuisance
trips from momentary voltage dips when the undervoltage trip feature is used.
