GE V7769-330001可以控制降壓?jiǎn)?dòng)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(shí)器”或“電流或定時(shí)器”(以先到者為準(zhǔn))。當(dāng)469測(cè)量到無(wú)電機(jī)電流到某個(gè)電機(jī)電流值的轉(zhuǎn)換時(shí),假設(shè)發(fā)生“啟動(dòng)”
(通常電流會(huì)迅速上升到超過(guò)FLA的值,例如3×FLA)。此時(shí),降低的電壓
START TIMER(啟動(dòng)定時(shí)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(shí),GE V7769-130001
轉(zhuǎn)換將通過(guò)激活指定的輸出繼電器1秒來(lái)啟動(dòng)。如果計(jì)時(shí)器在之前過(guò)期
該轉(zhuǎn)換啟動(dòng)時(shí),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(shí)器”,當(dāng)電機(jī)電流降至用戶編程的轉(zhuǎn)換水平以下時(shí),
轉(zhuǎn)換將通過(guò)激活指定的輸出繼電器1秒來(lái)啟動(dòng)。如果計(jì)時(shí)器在之前過(guò)期
如果啟動(dòng)了轉(zhuǎn)換,則將立即啟動(dòng)轉(zhuǎn)換。GE V7769-330001
如果選擇了“電流和定時(shí)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(shí)
并且計(jì)時(shí)器到期,將通過(guò)激活指定的輸出繼電器1秒來(lái)啟動(dòng)轉(zhuǎn)換。如果
定時(shí)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
