Overcurrent Trip Level: Typically used to
indicate the motor is severely overloaded and at
which point a trip
occurs.

Delay:   The
amount of time
the overcurrent condition must exist before a trip
will occur.

Phase Loss Trip:  When enabled, the TX will trip
the motor off-line upon a loss of phase power.

• Phase Loss Trip Delay:  The amount of time the

phase loss condition must exist before a trip will
occur.

Phase Rotation Detection:  The TX is
continuously monitoring the phase rotation. Upon
a start command, a trip will occur if it detects a
change in the phase rotation.

• Phase Rotation:  There are two possible phase

rotation options: ABC or ACB.  This setpoint
monitors the wiring to ensure that the phase
rotation is correct.  To view the present phase
rotation, go to  Metering Page1, screen number 4.

Ground Fault Alarm:  Typically used to warn of
low level ground current leakage

• Ground Fault Alarm Delay:  The amount of  time

that the ground fault condition must exist before an
alarm will occur.

Ground Fault Loset Trip Level:  Typically used
to trip the motor on a low level of ground current
leakage.  This setpoint is intended to detect high
impedance faults.  (Pending)

• Ground Fault Loset Trip Delay:  The amount of

time that the ground fault condition must exist
before a trip will occur.

SP3.10 Ground Fault Hiset Trip Level:  Used to trip

the motor (within milliseconds) upon detecting a
high level of ground current leakage.  This
setpoint is intended to detect low impedance
faults.  (Pending)

• Ground Fault Hiset Trip Delay:  The amount of

time that the ground fault condition must exist
before a trip will occur.

SP3.11 Overvoltage Alarm Level:  Typically used to

indicate when the line voltage is too high.  This is
an alarm level.

• Overvoltage Alarm Delay:  The amount of time

that the overvoltage condition must exist before a
trip will occur.
