    Program 300 minutes (5 hours) as the stopped cool time constant. Thus after 2 cold or 1 hot start, a stopped motor will be blocked from starting for 5 hours. ? Since the rotor cools faster when the motor is running, a reasonable setting for the running cool time constant might be half the stopped cool time constant or 150 minutes.

GE Power Management 469 Motor Management Relay E-1 APPENDIX E E.1 FIGURES AND TABLES E APPENDIX E APPENDIX EE.1 FIGURES AND TABLES E.1.1   1.1OVERVIEW 1.1.1 DESCRIPTION The 469 Motor Management Relay is a microprocessor based relay designed for the protection and management of medium 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 economical drawout package. The single-line diagram below illustrates the 469 functionality using ANSI (American National Standards Institute) device numbers. Figure 1–1: SINGLE LINE DIAGRAM Typical applications include: Some of the protection highlights are detailed here; a complete list is shown below. Four assignable digital inputs may be configured for a number of different features including tachometer or generic trip and alarm with a programmable name. The thermal model incorporates unbalance biasing, RTD feedback, and exponential cooling. In addition to the 15 standard overload curves, there is a custom curve feature and a curve specifically designed for the starting of high inertia loads, ? Pumps ? Fans ? Compressors ? Mills ?

Ground faults or earth leakage as low as 0.25 A may be detected using the GE Power Management 50:0.025 Ground CT. CT inputs for phase differential protection are also provided. The 12 RTD inputs provided may be individually field programmed for different RTD types. Voltage transformer inputs allow for numerous protection features based on voltage and power quantities. Four 4 to 20 mA analog inputs may be used for tripping and alarming on any transducer
