? ues will be substituted for the measured values may be used during startup or testing to verify that the output relays are functioning correctly. The output relays can only be forced to operate only if the motor is stopped and there are no trips, alarms, or start blocks active. If any relay is forced to operate, the relay will toggle from its normal state when there are no trips, alarms, or blocks to its active state. The appropriate relay indicator will illuminate at that time. Selecting "Disabled" places the output relays back in service. If the 469 measures phase current or control power is cycled, the FORCE OPERATION OF RELAYS setpoint will automatically become disabled and the output relays will revert back to their normal states. If any relay is forced, the 469 In Service LED will flash, indicating that the 469 is not in protection mode. 4.14.5 TEST ANALOG OUTPUT In addition to the simulation modes, the TEST ANALOG OUTPUT setpoint group may be used during startup or testing to verify that the analog outputs are functioning correctly. The analog outputs can only be forced if the motor is stopped and there are no trips, alarms, or start blocks active. When the FORCE ANALOG OUTPUTS FUNCTION is "Enabled", the output reflects the forced value as a percentage of the 4 to 20 mA or 0 to 1 mA range. Selecting "Disabled" places all four analog output channels back in service, reflecting the parameters programmed to each. If the 469 measures phase current or control power is cycled, the FORCE ANALOG OUTPUTS FUNCTION is automatically disabled and all analog outputs revert back to their normal state. Any time the analog outputs are forced, the 469 In Service LED will flash, indicating that the 469 S13 469 TESTING 4 4.14.6 COMM PORT MONITOR During the course of troubleshooting communications problems, it can be very useful to see the data that is first being transmitted to the 469 from some master device, and then see the data that the 469 transmits back to that master device. The messages shown here should make it possible to view that data. Any of the three communications ports may be monitored. After the communication buffers have been cleared, any data received from the communications port being monitored will be stored in the Rx1 and Rx2 buffers with ‘//’ acting as a character break between messages. If the 469 transmits a message, it will appear in the Tx1 and Tx2 buffers. In addition to these buffers, there is a message that will indicate the status Management Relay GE Power Management 4.15 S14 TWO-SPEED MOTOR 4 SETPOINT PROGRAMMING 4 4.15 S14 TWO-SPEED MOTOR 4.15.1 DESCRIPTION The two-speed motor feature provides proper protection for a two-speed motor where there will be two different full load values. The algorithm integrates the heating at each speed into one thermal model using a common thermal capacity used register value for both speeds. If the two-speed motor feature is used, ASSIGNABLE INPUT4 is dedicated as the two-speed motor monitor and terminals D22 and D23 are monitored for a contact closure. Closure of the contact signifies that the motor is in Speed 2. If the input is open, it signifies that the motor is in Speed 1. This allows the 469 to determine which setpoints should be active at any given point in time.

A second overload curve setup may be programmed here for Speed 2, High Speed. 4.15.3 SPEED2 UNDERCURRENT The addition of a second Undercurrent trip or alarm level may be useful as it will indicate if the wrong setpoints are being used for the wrong speed i.e. normal running current for Speed 2 may be undercurrent for Speed for more BLOCK SPEED2 U/C FROM START: 0 s Range: 0 to 15000 s, step 1 SPEED2 U/C ALARM: Off Range: Off, Latched, Unlatched SPEED2 U/C ALARM PICKUP: 0.70 x FLA Range: 0.10 to 0.95 x FLA, step 0.01 SPEED2 U/C ALARM DELAY: 1 s Range: 1 to 60 sec., step 1 SPEED2 U/C ALARM EVENTS: Off Range: On, Off SPEED2 U/C TRIP: 0ff Range: Off, Latched, Unlatched SPEED2 U/C TRIP PICKUP: 0.70 x FLA Range: 0.10 4.15 S14 TWO-SPEED MOTOR 4 4.15.4 SPEED2 ACCELERATION Two additional acceleration timers are provided for the two speed motor feature. One timer is for a start in Speed 2 from a stopped condition. The other is an acceleration timer for the transition from Speed 1 to Speed 2. Also, while the motor is running, the 469 will ignore Mechanical Jam protection during the acceleration from Speed 1 to Speed 2 until the motor current has dropped below Speed 2 FLA × Overload Pickup value, or the Speed 1-2 acceleration time has expired. At that point in time, the Mechanical Jam feature will be enabled with the Speed 2 FLA ? s Range: 1.0 to 250.0 sec., step: 0.1 Seen only if one of the digital inputs is assigned as Speed Switch SPEED2 RATED SPEED: 3600 RPM Range: 100 to 7200 RPM; Step: 1 Seen only if one of the digital inputs is assigned as Measured values, maintenance and fault analysis information are accessed in Actual Value mode.
