Product Processing


SQ3W series automatic transfer switch can adopt the manual operation mode, when the manual operation is used, the manual/auto button is set in the "manual" position, when the handle is rotated clockwise to the terminal, thus, the reserve power actuating breaker QR is switched off, and the normal power actuating breaker QN is switched on.

On the contray, when the handle is rotated CCW to the terminal, the reserve power actuating breaker QR is switched on, and the normal power actuating breaker QN is switched off. The panel power indicating lamp (yellow) indicates the working voltage of automatic controller, if this lamp is not bringhtened, this means the working power of automatic controller has the failure, and the switch should not be operated.

After it is recovered, the manual/auto button should be set to the automatic position, if the normal power is in the mormal state,the normal power actuating breaker QN will be in the ON state, thus, the panrl N power indicating lamp(green) is bringhtened; if the normal power is abnormal, the normal power actuating breaker QN will be in the OFF state, and reserve power actuating breaker QR will be in the ON state, thus, the panel R power indicating lamp(green) is brightened.
