求翻译：如果接触器吸合后发出连续的“哒，哒，哒”的噪声，可能由于接触器中落入异物使得接触器铁芯无法正常吸合是什么意思？

If the contactor to send continuous "da, da, da" noise, falling into the foreign body may be due to the contactor in the contactor iron core can not pull

If contactor closed after a continuous, Click, Click'"'noise, and may be due in contactor fallen iron core material makes contactor cannot be properly closed

If after the contact device attracts gathers sends out continual “clip clop, clip clop, clip clop” noise, possible because the contact device declines into the foreign matter to cause the contact device ferrite core to be unable to attract normally gathers

If the contactor emitted after pull-in consecutive "da, da, da" noise, may be due to contact in the hands of foreign body makes contactor cores cannot be normal suction
