|
Operator Interface
Tactile feedback keypad
Easy to read LED display
Run and fault
status indicators.
|
|
Ramp Control Choices (4 built-in)
Voltage Ramp
Voltage Ramp with Current Limit
CLT© Closed Loop Torque Ramp (Current Ramp)
Current Step (current limit only)
Ramp times adjustable 1 - 120 seconds
Current Limit adjustable 200 - 600% of FLA
|
Electronic Shear Pin Protection
Trip level: 100 - 300% of motor FLA with trip delay
|
|
Dual Ramps
Select via dry contact closure between any
combinations of the above
|
Motor Duty Cycle Protection
Back-spin/coast-down, starts-per-hour or minimum
time between starts lockouts. Restart delay after a
power failure.
|
|
Start & Run Protection
Two programmable overload trip curves allow for the
thermal capacity required to start the load while providing
motor overload protection needed during the run time.
Start: Programmable for Class 5 - 30
Run: Programmable for Class 5 - 30, enabled when starter
detects motor is "At-Speed"
Reset: Manual or automatic, selectable via programming.
Remote reset available.
|
Short Circuit
Trips at 10x unit current rating during run. Checks for
shorted load prior to each start.
|
|
Real-Time Thermal Modeling
Continuously calculates motor operating temperature even
when the motor is not running.
|
Shorted SCR
Locks out on any single shorted SCR (defeatable) or
can provide shunt trip function if multiple SCRs short
or bypass contactor is welded closed.
|
|
Retentive Thermal Memory
Remembers the thermal condition of the motor even in the
event of a power brown-out or black-out when power is
restored. Extrapolates motor temperature using a real-time
clock.
|
Metering
Monitors phase current, ground current and motor
thermal capacity.
|
|
Dynamic Reset Capacity
Overload will not reset until thermal capacity in the motor is
sufficient for a successful restart. Starter learns and retains this
information from previous starts.
|
Phase Loss
Trips on phase current or voltage loss
|
|
Motor Temperature
PTC thermistor input can also be used for E-stop or external
overload relay.
|
Phase Rotation
Phase rotation trip can be set to A-B-C, A-C-B or disabled.
|
|
Equipment Ground Fault
Residual current method with adjustable trip delay.
|
|
|
Phase Current Imbalance/Loss Protection
Trip level: 5 - 30% current imbalance between any two
phases with trip delay
