GE V7769-330001可以控制降压启动器从降压到满压的转换。这种转变可能
基于“仅限电流”、“电流和定时器”或“电流或定时器”（以先到者为准）。当469测量到无电机电流到某个电机电流值的转换时，假设发生“启动”
（通常电流会迅速上升到超过FLA的值，例如3×FLA）。此时，降低的电压
START TIMER（启动定时器）用编程值（秒）进行初始化。
•GE V7769-330001如果选择“Current Only”（仅限电流），当电机电流降至用户编程的转换电平以下时，GE V7769-130001
转换将通过激活指定的输出继电器1秒来启动。如果计时器在之前过期
该转换启动时，GE V7769-330001将发生不完整序列跳闸，激活指定的跳闸继电器。
•GE V7769-330001如果选择“电流或定时器”，当电机电流降至用户编程的转换水平以下时，
转换将通过激活指定的输出继电器1秒来启动。如果计时器在之前过期
如果启动了转换，则将立即启动转换。GE V7769-330001
如果选择了“电流和定时器”GE V7769-330001，当电机电流降至用户编程的转换水平以下时
并且计时器到期，将通过激活指定的输出继电器1秒来启动转换。如果
定时器在电流降至转换电平以下之前到期，将发生不完整顺序跳闸，激活指定的跳闸继电器。GE V7769-330001

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
