? ues將代替測量值，可在啟動或測試期間使用，以驗證輸出繼電器是否正常工作。只有當電機停止且沒有跳閘、報警或啟動塊激活時，輸出繼電器才能強制運行。如果任何繼電器被強制運行，則繼電器將從其正常狀態（無跳閘、報警或閉塞）切換至其激活狀態。此時，相應的繼電器指示燈將點亮。選擇“禁用”將使輸出繼電器重新投入使用。如果469測量相電流或控制功率循環，則繼電器的強制操作設定值將自動禁用，輸出繼電器將恢復到正常狀態。如果強制任何繼電器，469在用LED將閃爍，表明469未處于保護模式。4.14.5測試模擬輸出除模擬模式外，在啟動或測試期間，可使用測試模擬輸出設定值組來驗證模擬輸出是否正常工作。只有當電機停止且沒有跳閘、報警或啟動塊激活時，才能強制模擬輸出。當FORCE ANALOG OUTPUTS FUNCTION（強制模擬輸出功能）為“Enabled”（啟用）時，輸出將強制值反映為4至20 mA或0至1 mA范圍的百分比。選擇“Disabled”（禁用）將使所有四個模擬輸出通道重新投入使用，反映為每個通道編程的參數。如果469測量相電流或循環控制電源，則FORCE ANALOG OUTPUTS FUNCTION（強制模擬輸出功能）將自動禁用，所有模擬輸出將恢復到正常狀態。每當模擬輸出被強制時，469在用LED將閃爍，表明469 S13 469 TESTING 4 4.14.6 COMM PORT MONITOR（通信端口監視器）在對通信問題進行故障排除的過程中，查看從某個主設備首先傳輸到469的數據，然后查看469傳輸回該主設備的數據非常有用。此處顯示的消息應該可以查看該數據。可以監控三個通信端口中的任何一個。清除通信緩沖區后，從被監控的通信端口接收的任何數據將存儲在Rx1和Rx2緩沖區中，“//”用作消息之間的字符分隔符。如果469發送消息，它將出現在Tx1和Tx2緩沖器中。除這些緩沖器外，還有一條消息將指示狀態管理繼電器GE電源管理4.15 S14雙速電機4設定點編程4.15 S15雙速電機4.15.1說明雙速電機功能為兩個不同滿載值的雙速電機提供適當保護。該算法使用兩種速度的常用熱容量寄存器值將每種速度下的加熱集成到一個熱模型中。如果使用雙速電機功能，ASSIGNABLE INPUT4專用于雙速電機監視器，端子D22和D23用于觸點閉合。觸點閉合表示電機處于速度2。如果輸入打開，則表示電機處于速度1。這允許469確定在任何給定時間點應激活哪些設定點。SPEED2 MIN ALLOWABLE LINE VOLTAGE（速度2最小允許線路電壓）：80%范圍：70至95%；步驟：1僅當選擇了電壓相關曲線樣式時才顯示消息SPEED2 ISTALL@MIN Vline:4.80 x FLA范圍：2.00至15.00 x FLA；步驟：僅當選擇了電壓相關曲線樣式時才顯示0.01消息SPEED2 SAFE STALL@MIN Vline:2.0 s范圍：0.5至999.9秒；步驟：僅當選擇“電壓相關曲線樣式”時才顯示0.1消息SPEED2 ACL INTERSECT@MIN Vline:3.80 x FLA范圍：2.00至Istall@Min_Vlinex FLA；步驟：僅當選擇了電壓相關曲線樣式SPEED2 4.15 S14雙速電機4設定點編程4時，才會看到0.01消息。速度1的所有熱模型參數設置將與速度2相同。此處可為速度2、高速編程第二過載曲線設置。4.15.3速度2欠電流增加第二個欠電流跳閘或報警級別可能很有用，因為它將指示錯誤的速度是否使用了錯誤的設定值，即速度2的正常運行電流可能是欠電流，速度為更多的BLOCK SPEED2 U/C FROM START:0 s Range：0 to 15000 s，步驟1速度2 U/C alarm：Off Range：Off，Latched，未鎖定的SPEED2 U/C警報拾取：0.70 x FLA范圍：0.10至0.95 x FLA，步驟0.01 SPEED2 U/C警報延遲：1 s范圍：1至60秒，步驟1 SPEED2 U-C警報事件：關閉范圍：打開，關閉速度2 U/C跳閘：0ff范圍：關閉，鎖定，未鎖定速度2 U/C跳閘傳感器：0.70 x FLA范圍：0.10 4.15 S14雙速電機4 4.15.4速度2加速度雙速電機功能提供了兩個額外的加速計時器。一個計時器用于從停止狀態啟動速度2。另一個是用于從速度1轉換到速度2的加速計時器。此外，雖然t
? 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.
