XTJY WYE DELTA (STAR-DELTA) JOCKEY PUMP CONTROLLERS
Model XTJY Wye-Delta controllers are used when six or twelve-lead delta connected jockey pump motors are started wye (star) – connected. Approximately 58% of line voltage is applied to each winding and the motor develops 33% of full-voltage starting torque and draws 33% of normal locked-rotor current from the line. After a 2 second time delay (during which the motor accelerates), it is reconnected for normal delta operation.
- Circuit Breakers
XTJY Jockey Pump Controllers incorporate Eaton Combination Motor Controllers, which combine the circuit breaker and overload in one device.
- Digital Display
They are also supplied standard with an 1/8 DIN, NEMA 4X Digital Panel Meter that displays current pressure, hi and low set points and two alarm set points on a 4-digit, superbright LED display. Pressure input is provided by a 4-20mA pressure sensor.
- Control Transformer
All jockey pump controllers are wired with a 120V control power transformer as standard.
