GE V7769-330001可以控制降壓啟動器從降壓到滿壓的轉(zhuǎn)換。這種轉(zhuǎn)變可能

基于“僅限電流”、“電流和定時器”或“電流或定時器”（以先到者為準(zhǔn)）。當(dāng)469測量到無電機(jī)電流到某個電機(jī)電流值的轉(zhuǎn)換時，假設(shè)發(fā)生“啟動”

（通常電流會迅速上升到超過FLA的值，例如3×FLA）。此時，降低的電壓

START TIMER（啟動定時器）用編程值（秒）進(jìn)行初始化。

?GE V7769-330001如果選擇“Current Only”（僅限電流），當(dāng)電機(jī)電流降至用戶編程的轉(zhuǎn)換電平以下時，GE V7769-130001

轉(zhuǎn)換將通過激活指定的輸出繼電器1秒來啟動。如果計時器在之前過期

該轉(zhuǎn)換啟動時，GE V7769-330001將發(fā)生不完整序列跳閘，激活指定的跳閘繼電器。

?GE V7769-330001如果選擇“電流或定時器”，當(dāng)電機(jī)電流降至用戶編程的轉(zhuǎn)換水平以下時，

轉(zhuǎn)換將通過激活指定的輸出繼電器1秒來啟動。如果計時器在之前過期

如果啟動了轉(zhuǎn)換，則將立即啟動轉(zhuǎn)換。GE V7769-330001

如果選擇了“電流和定時器”GE V7769-330001，當(dāng)電機(jī)電流降至用戶編程的轉(zhuǎn)換水平以下時

并且計時器到期，將通過激活指定的輸出繼電器1秒來啟動轉(zhuǎn)換。如果

定時器在電流降至轉(zhuǎn)換電平以下之前到期，將發(fā)生不完整順序跳閘，激活指定的跳閘繼電器。GE V7769-330001

英文資料：

GE V7769-330001 can control the transition of a reduced voltage starter from reduced to full voltage. That transition may

be based on "Current Only", "Current and Timer", or "Current or Timer" (whichever comes first). When the 469 measures the transition of no motor current to some value of motor current, a 'Start' is assumed to be occurring

(typically current will rise quickly to a value in excess of FLA, e.g. 3 × FLA). At this point, the REDUCED VOLTAGE

START TIMER is initialized with the programmed value in seconds.

?GE V7769-330001 If "Current Only" is selected, when the motor current falls below the user's programmed Transition Level,GE V7769-330001

transition will be initiated by activating the assigned output relay for 1 second. If the timer expires before

that transition is initiated, GE V7769-330001an Incomplete Sequence Trip will occur activating the assigned trip relay(s).

?GE V7769-330001 If "Current or Timer" is selected, when the motor current falls below the user's programmed Transition Level,

transition will be initiated by activating the assigned output relay for 1 second. If the timer expires before

that transition is initiated, the transition will be initiated regardless.GE V7769-330001

If "Current and Timer" GE V7769-330001 is selected, when the motor current falls below the user's programmed Transition Level

and the timer expires, transition will be initiated by activating the assigned output relay for 1 second. If the

timer expires before current falls below the Transition Level, an Incomplete Sequence Trip will occur activating the assigned trip relay(s).GE V7769-330001
