connectors 2.Frequency converter malfunctionCheck the
fault content, check the cause according to the frequency converter
manual, and restart after reset.Or disconnect the inverter power
supply for a few seconds, the inverter fault reset before
starting.The manual is normal3The frequency converter is

non - suction pressure gauge pointer to beat violentlyInsufficient
water supply for perfusion, air leakage at the connection between
pipeline and instrumentCheck pipeline and bottom valve, refill
water diversion. Tighten air leakageThe pump consumes too much
power Too much flow, impeller wear Check whether the pump
shaft is bent, replace the impeller, close the outlet valve to
reduce the flow/* March 10, 2023 17:59:20 */!function(){function
