s backlit for visibility under poor lighting conditions. Messages are displayed in plain English and do not require an instruction manual to decipher. When the keypad and display are not being used, the display defaults to the user-defined status messages. Any trip, alarm, or start block is displayed immediately, automatically overriding the default messages. 3.1.2 LED INDICATORS There are three groups of LED indicators. They are 469 Status, Motor Status, and Output Relays. Figure 3–1: 469 LED INDICATORS a) 469 STATUS LED INDICATORS • 469 IN SERVICE: This LED indicates that control power is applied, all monitored inputs/outputs and internal systems are OK, the 469 has been programmed, and the 469 is in protection mode, not simulation mode. This LED flashes when the 469 is in simulation or testing mode. • SETPOINT ACCESS: This LED indicates that the access jumper is installed and passcode protection has been satisfied; setpoints may be altered and stored. • COMPUTER RS232: This LED flashes when there is any activity on the communication port. The LED remains on solid if incoming data is valid. • COMPUTER RS485: Flashes when there is any activity on the communication port. Remains on solid if incoming data is valid and intended for the slave address programmed in the relay. • AUXILIARY RS485: Flashes when there is any activity on the communication port. Remains on solid if incoming data is valid and intended for the slave address programmed in the relay. • LOCKOUT: Indicates start attempts will be blocked either by a programmed lockout time or a condition that is still present. • RESET POSSIBLE: A trip or latched alarm may be reset. Press the key to clear the trip or alarm. • MESSAGE: Flashes when a trip, alarm, or start block occurs. Pressing the key scrolls through diagnostic messages. This LED remains solid when setpoint and actual value messages are being viewed. Pressing the key returns the display to the default messages. b) MOTOR STATUS LED INDICATORS • STOPPED: The motor is stopped based on zero phase current and starter status auxiliary contact feedback. • STARTING: Motor is starting. • RUNNING: Motor is running normally below overload pickup level. • OVERLOAD: Motor is running above overload pickup. • UNBALANCE PICKUP: Level of current unbalance has exceeded the unbalance alarm or trip level. • GROUND PICKUP: Level of ground current has exceeded the ground fault alarm or trip level. • HOT RTD: One of the RTD measurements has exceeded its RTD alarm or trip level. 808706A2.CDR RESET NEXT NEXT 3-2 469 Motor Management Relay GE Multilin 3.1 FACEPLATE INTERFACE 3 USER INTERFACES 3 • LOSS OF LOAD: Average motor current has fallen below the undercurrent alarm or trip level; or power consumption has fallen below the underpower alarm or trip level. c) OUTPUT RELAY LED INDICATORS • R1 TRIP: R1 Trip relay has operated (energized). • R2 AUXILIARY: R2 Auxiliary relay has operated (energized). • R3 AUXILIARY: R3 Auxiliary relay has operated (energized). • R4 ALARM: R4 Alarm relay has operated (energized). • R5 BLOCK START: R5 Block Start relay has operated (energized). • R6 SERVICE: R6 Service relay has operated (de-energized, R6 is failsafe, normally energized). 3.1.3 RS232 PROGRAM PORT This port is intended for connection to a portable PC. Setpoint files may be created at any location and downloaded through this port with the 469PC software. Local interrogation of setpoints and actual values is also possible. New firmware may also be downloaded to the 469 flash memory through this port. Upgrading of the relay firmware
