Figure 4-1 REDUCED VOLTAGE START CONTACTOR CONTROL CIRCUIT
Figure 4-2 REDUCED VOLTAGE STARTING CURRENT CHARACTERISTIC
NOTE: If this feature is used, Starter Status Switch input must be either from a common control contact or a parallel combina-
tion of Auxiliary ‘a’ contacts or a series combination of Auxiliary ‘b’ contacts from the reduced voltage contactor and the full
voltage contactor. Once transition is initiated, the SR469 will assume the motor is still running for at least 2 seconds. This will
prevent the SR469 from recognizing an additional start if motor current goes to zero during an open transition.
