AC Supply Voltage
200 to 600 Vac

HP Ratings

10 to 1125 HP

(39 to 1250 Amps)

Acceleration Adjustments Ramp types

Voltage ramp or current ramp Starting torque 0 - 100% of line voltage or 0 - 600% of FLA Ramp time 1 to 120 seconds Current limit 200 - 600%

Retentive Thermal Memory

Overload circuit retains thermal condition of the motor regardless of control power status. Unit uses real time clock to adjust for off time

Dual Ramp Settings*

Four (4) programmable ramp options

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.

Deceleration Adjustments

Begin decel level 0 - 100% of line voltage

Stop level 0 to 1% less than begin decel

Decel time 1 - 60 seconds

Phase Current Imbalance/Loss Protection

Imbalance trip level 5 - 30% current between any two phases Imbalance trip delay 1 - 20 seconds

Electronic Shear Pin Protection Shear pin trip level 100 - 300% of motor FLA Shear pin trip delay 1 - 20 seconds

Jog Settings*

Voltage jog 5 - 100%

Kick Start Settings

Kick Voltaqe 10 - 100%

Kick start time 0.1 - 2 seconds

Starts-per-Hour Lockout Timer

Starts-per-hour 1 - 10 successful starts per hour

Time between starts 1 - 60 min. between start attempts

Programmable Output Relays

Protection 4 relays; 1 Form C (DPDT), 3 Form A (SPST NO)

5A 240VAC max. (1200VA),

Individually programmable to 19 functions

Event History

Up to 60 events; data includes event, time, date and current for each phase and ground fault current at time of event

Options

Ground Fault: Residual or Zero Sequence

RTD Inputs: Up to 12 RTD’s of any type with biasing or override protection curve

Protection

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

The DXT Series recognizes motor cool-down rates are a function of the run time and that sometimes a motor will cool faster if allowed to run.

Metering Functions

Motor Load: Percent of FLA

Current Data: A, B, C Phase Current, Avg Current, Ground Fault

Thermal Data: Remaining thermal register; thermal capacity to start

Start Data: Avg Start time, Avg Start Current, Measured Capacity to start, time since last start

RTD Data (Option): Temperature readings from up to 12 RTDs (6 stator RTDs)

Voltage Metering: V, KW, KVAR, PF, KWH, Demand
