英文資料：

GE V7769-SDK-LNX-B this feature is used, the Starter Status Switch input must be either from a common control contact or a parallel combination of Auxiliary ‘a(chǎn)’ contacts or a series combination of Auxiliary ‘b’ contacts from the reduced voltage contactor and the full voltage contactor. Once transition is initiated, the 469 assumes the motor is still running for at GE V7769-SDK-LNX-Bleast 2 seconds. This prevents the GE V7769-SDK-LNX-B from recognizing an additional start if motor current goes to zero during an open transition.

Setpoints page 3 has been designated the DIGITAL INPUTS page. The 469 has nine digital inputs. Five of the GE V7769-SDK-LNX-B digital inputs have been pre-assigned as switches having a specific function. Four of the five pre-assigned digital inputs are always functional and do not have any setpoint messages associated with them.GE V7769-SDK-LNX-B

The fifth, Starter Status, may be configured for either an 'a' or 'b' auxiliary contact. The remaining four digital inputs are assignable; that is to say, the function that the input is used for may be chosen from one of a number of different functions. Some of those functions are very specific, others may be programmed to adapt to the user requirements. If the Two-Speed Motor feature is enabled, ASSIGNABLE INPUT 4 will be dedicated as the Two-Speed Motor Monitor.GE V7769-SDK-LNX-B
