• 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. • 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). 3.1.4 RS232 PROGRAM PORT Figure 3–4: 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 does not require a hardware EPROM change. 3-4 469 Motor Management Relay GE Power Management 3.1 OVERVIEW 3 OPERATION 3 3.1.5 KEYPAD Figure 3–5: 469 KEYPAD The 469 messages are organized into pages under the headings Setpoints and Actual Values. The key navigates through the programmable parameters page headers. The key navigates through the measured parameters page headers. Each page is broken down further into logical subgroups of messages. The and keys may be used to navigate through the subgroups. The key is dual purpose. It is used to enter the subgroups or store altered setpoint values. The key is also dual purpose. It may be used to exit the subgroups or to return an altered setpoint to its original value before it has been stored. The and keys scroll through variables in the setpoint programming mode and increment/ decrement numerical setpoint values. Alternately, these values may be entered with the numeric keypad. The key may be pressed at any time to display context sensitive help messages. 3.1.6 ENTERING ALPHANUMERIC TEXT To customize the 469 for specific applications, custom text messages may be programmed in several places. One example is the Message Scratchpad. To enter alphanumeric text messages, the following procedure should be followed: For example, to enter the text "Check Fluid Levels": 1. Press the decimal key [.] to enter text editing mode. 2. Press the or keys until C appears, then press the decimal key [.] to advance Negative numbers may be entered in one of two manners. • Immediately pressing the or keys causes the setpoint to scroll through its range including any negative numbers. • After entering at least one digit of a numeric setpoint value, pressing the or keys will change the sign of the value where applicable.
