TOSHIBA- 37
TX Series 48 - 1250A
SP.3 Phase & Ground Settings (Setpoint Page 3)
(Security Level: 2)
Note: 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.
SP3.1 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.
SP3.2 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.
SP3.3 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.
SP3.4 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.
