MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE GE Multilin 469 Motor Management Relay 4-11 4 SETPOINTS 4.2 S1 469 SETUP 4 These commands may be used to clear various historical data. ? CLEAR LAST TRIP DATA: Clears the last trip data. ? RESET MWh and Mvarh METERS: Resets the MWh and Mvarh metering to zero. ? CLEAR PEAK DEMAND DATA: Clears the peak demand values. ? CLEAR RTD MAXIMUMS: All maximum RTD temperature measurements are stored and updated each time a new maximum temperature is established. This command clears the maximum values. ? CLEAR ANALOG I/P MIN/MAX: The minimum and maximum analog input values are stored for each analog input. These minimum and maximum values may be cleared at any time. ? CLEAR TRIP COUNTERS: There are counters for each possible type of trip. This command clears these counters. ? PRESET DIGITAL COUNTER: When one of the assignable Digital Inputs is configured as “Counter”, this command presets the counter. If the counter is an incrementing type, setting the preset value to “0” effectively resets the counter. ? CLEAR EVENT RECORD: The event recorder saves the last 40 events, automatically overwriting the oldest event. If desired, this command can clear all events to prevent confusion with old information. 4.2.8 INSTALLATION PATH: SETPOINTS ? S1 469 SETUP ?× INSTALLATION These commands clear various informative and historical data when the 469 is first applied on a new installation. ? RESET MOTOR INFORMATION: Counters for number of motor starts and emergency restarts can be viewed in actual values. The 469 also learns various motor characteristics through motor operation. These learned parameters include acceleration time, starting current, and starting thermal capacity. Total motor running hours may also be viewed in actual values. On a new installation or if new equipment is installed, all this information can be reset with this setpoint. ? RESET STARTER INFORMATION: The total number of starter operations can be viewed in actual values. Use this setpoint to clear this counter on a new installation or if maintenance work is done on the breaker or contactor. n INSTALLATION n [ENTER] for more RESET MOTOR INFORMATION: No Range: No, Yes RESET STARTER INFORMATION: No Range: No, Yes ENTER ESCAPE e e MESSAGE ESCAPE 4-12 469 Motor Management Relay GE Multilin 4.3 S2 SYSTEM SETUP 4 SETPOINTS 4 4.3S2 SYSTEM SETUP 4.3.1 CURRENT SENSING PATH: SETPOINTS ?× S2 SYSTEM SETUP ?
