B-3GE Multilin469 Motor Management Relay1-11 OVERVIEW11 INTRODUCTION DESCRIPTIONThe 469 Motor Management Relay is a microprocessor based relay designed for the protection and management ofmedium and large horsepower motors and driven equipment. The 469 is equipped with six output relays for trips, alarms,and start blocks. Motor protection, fault diagnostics, power metering, and RTU functions are integrated into one economicaldrawout package. The single-line diagram below illustrates the 469 functionality using ANSI (American National StandardsInstitute) device 1 1: SINGLE LINE DIAGRAMT ypical applications include:Some of the protection highlights are detailed here; a complete list is shown below.

8 Four assignable digital inputs may beconfigured for a number of different features including tachometer or generic trip and alarm with a programmable thermal model incorporates unbalance biasing, RTD feedback, and exponential cooling. In addition to the 15 standardoverload curves, there is a custom curve feature and a curve specifically designed for the starting of high inertia loads, Pumps Fans Compressors Mills Shredders Extruders Debarkers Refiners Cranes Conveyors Chillers Crushers Blowers1-2469 Motor Management RelayGE OVERVIEW1 INTRODUCTION1when the acceleration time exceeds the safe stall time. A second overload curve is provided for two-speed motors.

9 Groundfaults or earth leakage as low as A may be detected using the GE Power Management 50 Ground CT. CT inputsfor phase differential protection are also provided. The 12 RTD inputs provided may be individually field programmed fordifferent RTD types. Voltage transformer inputs allow for numerous protection features based on voltage and power quanti-ties. Four 4 to 20 mA analog inputs may be used for tripping and alarming on any transducer input such as vibration, pres-sure, flow, 1 2: PROTECTION FEATURESF ault diagnostics are provided through pretrip data, event record, trace memory, and statistics. Prior to issuing a trip, the469 takes a snapshot of the measured parameters and stores them with the cause of the trip.

10 This pre-trip data may beviewed using the key before the trip is reset, or by accessing the A1 STATUS LAST TRIP DATA actual values. The469 event recorder stores up to 40 time and date stamped events including the pre-trip data. Each time a trip occurs, the469 stores a trace of 8 cycles pre-trip and 8 cycles post-trip for all measured AC quantities. Trip counters record the numberof occurrences of each type of trip. Minimum and maximum values for RTDs and analog inputs are also recorded. Thesefeatures enable the operator to pinpoint a problem quickly and with metering included with the 469 as a standard feature.
