The German FLFE company's synchronous camera, which is equipped with an imported gravure printing press, produces a malfunction in the production of the camera lamp that does not flash.

Check the data to understand the camera, through the computer to control the camera lamp, with the camera, the lamp synchronization flash, the camera synchronously to take pictures of the printed product, and displayed through the display, so that operators can always observe the product Situation, timely adjustments to ensure the quality of printed products. We used an oscilloscope to check and found that the computer's sync trigger pulse was already present, but there was no voltage across the flash tube. Check the circuit board again and find that the transformer has been burned. Put on the domestic transformer BK-40, with the manual button to make the flash flash, found that the transformer secondary old V power current changes greatly, it is suspected that the oscillating step-up transformer short circuit, so that the original transformer burned. Detected with a multimeter is a winding short circuit in the oscillating step-up transformer. After rewinding, troubleshooting is performed.
