Advanced Protection and Monitoring Capabilities
This relay is microcomputer-controlled and keypad programmable, allowing for flexible configuration. Its protection features are extensive, including pre-trip alarm warnings, emergency restart capability, variable lockout time, phase reversal, ground fault, short-circuit protection, and detection of unbalance/single phasing. It effectively handles trip/mechanical jams, locked rotors, and undercurrent for load loss. For thermal protection, it offers 8 standard overload curves and a user-defined FlexCurve, further enhanced by a thermal model biased with RTD and negative sequence current feedback, as well as monitoring for stator winding and bearing overtemperature. The unit also supports multiple motor starts.
Beyond protection, the 269PLUS-100P-120 excels in monitoring and metering, offering optional voltage and power metering, learned and statistical data, a data logger, and current/thermal capacity metering. It integrates 12 programmable RTDs, 5 factory-programmed digital inputs, 4 output relays (including latched main trip, alarm, and two auxiliary relays), and 1 programmable analog output. Communication with programmable controllers and computers is facilitated for integrated plant control, and the relay utilizes EnerVista software for comprehensive management. – AX Control Technician
