What to do if the laser circuit’s flow alarm rings? First, you can press the up or down key to check the flow rate of the laser circuit. Alarm will be triggered when the value falls below 8, it may be caused by the Y-type filter clogging of the laser circuit water outlet.Turn off the chiller, find the Y-type filter of the laser circuit water outlet, use an adjustable wrench to remove the plug anticlockwise, take out the filter screen, clean and install it back, remember not to lose the white sealing ring on the plug. Tighten the plug with wrench, if the flow rate of laser circuit is 0, it is possible that the pump is not working or the flow sensor fails. Open the left-side filter gauze, use a tissue to check whether the back of the pump will aspirate, if the tissue is sucked in, it means the pump is working normally, and there may be something wrong with the flow sensor, feel free to contact our after-sales team to solve it. If pump is not working properly, open the electric box, measure the voltage at the lower end of the leftmost alternating current contactor. See if three phases are all stable at 380V, if not, it means there is a problem with the voltage. But if the voltage is normal and stable, the flow alarm still can’t be troubleshot, please contact our after-sales team immediately.
