Proper phase sequence must be observed when
connecting the input power. For example, phase A
must lead phase B, which in turn must lead phase
C by 120° respectively. If the phase rotation is not
correct, a fault light and the LCD display will
indicate the problem.

Imbalance Alarm Level:  This is an advance
warning of a phase imbalance problem.  The
problem may not be a fault in the motor, but merely
caused by imbalanced voltages.

• Imbalance Alarm Delay: The amount of time the

imbalance condition must exist before an alarm
occurs.

Imbalance Trip Level: This will trip the motor on
excessive phase imbalance.  The trip level should
be programmed to a higher value than the alarm
level.

• Imbalance Trip Delay: The amount of time the

imbalance condition must exist before a trip will
occur.

Undercurrent Alarm Level: Typically used to
warn of possible load loss, a coupling breaking or
other mechanical problems.

• Undercurrent Alarm Delay: The amount of time

the undercurrent condition must exist before an
alarm will occur.

Overcurrent  Alarm Level: Typically used to
indicate when the motor is overloaded.  This feature
can be used to either stop the feed to the
equipment or warn operators of an overload
condition.

• Overcurrent Alarm Delay: The amount of time

the overcurrent condition must exist before an
alarm will occur.
