Cause the unit to automatically shut down or a protection project photoacoustic signal is as follows: The output voltage is too low, less than 320V (size can be set) output voltage is too high, higher than 450V (size can be set) output current is too high, Taiwan GTR168, Size can be set (depending on power generating units) frequency is too high, the English GTR168, higher than 60Hz (size can be set) frequency is too low, lower than 40Hz (size can be set) low speed emergency stop, macro Jin GTR168, has emergency stop button failed to start, GTR168, three times failed to start alarm (size can be set) oil pressure is too low, lower than what is unloading machine before 1.5bar order? A: Remove the load from small to large order, and finally shut down. 44, why not take a load off, boot? A: The case of an emergency stop with a load off, the unit greater impact. Power belongs to the illegal operations with a load on the power plant will bring damage to electrical equipment. GTR168, faithful electromechanical, GTR-168 provided by the Dongguan City, South City Zhongxin Electrical and Mechanical operation. GTR168, faithful electromechanical, GTR-168 is in Dongguan City, South City Zhongxin Electrical and operating (zhongxin888.net.cn) this year introduced a new upgrade, the above picture is for reference only, please call the telephone or pictures on this page, for the latest Information, Contact: Miss Li.
