When it is low brightness, the current is small, 3DG6 turns off, 3DG12 turns off, relay has no action. When it has light, 3DG6 turns on, 3DG12 turns on, relay pulls up. The baiting gate is controlled by relay, it can accomplish the aim of baiting as the desired value. 2CP12 is used to prevent the Back EMF released by relay. This automatic gravimetric filling instrument can set value with 0.5kg graduation discretionarily in the range of 0~30kg, the precision can reach millesimal.
