The ratings of the phase current inputs (1A and 5A) must be specified when ordering the relay, while the ratings for differential inputs are field programmable, supporting both 1A and 5A secondary currents. There are also 2 single-phase ground CT inputs: A standard input with settable secondary rating; 5A or 1A, and a high sensitivity ground current detection input for high resistance grounded systems. Three phase VT inputs support delta and wye configuration and provide voltage signals for all voltage, frequency and power based protection elements and metering. Digital Inputs The 469 has 5 predefined inputs: • Starter Status • Emergency Restart • Remote Reset • Setpoint Access • Test Switch The 469 also has four assignable digital inputs, which can be configured as the following functions: • Remote Trip and Alarm • Speed Switch Trip and Tachometer • Vibration Switch Trip and Alarm • Pressure Switch Trip and Alarm • Load Shed Trip • Universal Digital Counter • External oscillography trigger and External Relay Fault Simulation initiation • General Switch with programmable functions and outputs Analog Inputs and Outputs Use the four configurable analog inputs available in the 469 to measure motor operation related quantities fed to the relay from standard transducers. Each input can be individually set to measure 4-20 mA, 0-20 mA or 0-1 mA transducer signals. The 469 can also 469 Motor Protection System GEGridSolutions.com 5 be set to issue trip or alarm commands based on signal thresholds. Use the four configurable analog outputs available in the 469 to provide standard transducer signals to local monitoring equipment. The desired output signal must be specified when the relay is ordered, either 4-20 mA, or 0-1 mA. The analog outputs can be configured to provide outputs based on any measured analog value, or any calculated quantity. Output Relays There are six Form-C output relays available in the 469. Four relays are always non-failsafe and can be selectively assigned to perform trip, or alarm functions. A non-failsafe block start relay is also provided, controlled by protection functions requiring blocking functionality. Loss of control power or 469 internal failures are indicated via the failsafe service relay. The trip and alarm relays can also be configured with latching functionality. Monitoring and Metering The 469 includes high accuracy metering and recording for all AC signals. Voltage, current, RTD and power metering are built into the relay as a standard feature. Metering The following system values are accurately metered and displayed: • Phase, differential and ground currents, average current, motor load, current unbalance.
