There are many parameters of the tachometer, similar to the digital display. The two of us use the first one to set the first alarm point. The second is the upper and lower limits of the transmission output.
Press the setting button for more than 2 seconds to release the first group of parameters RU, press the confirmation button to select the first parameter of the group alarm parameter setting parameter RH=3160
After setting, continue to press the setting button for more than 2 seconds to enter the next group of parameters, continue to enter the fourth group of Add settings
Transmission output upper limit BA-H=5000
Transmission output lower limit BA-L=0
Xi'an Huaheng meter reminds: the gap between the speed sensor and the gear is 1--1.5mm. The bearing temperature is 35-60 normal, and the 65 degree alarm does not trip. The steam turbine has only three tachometers set the first alarm value 3 select 2 alarm when the jump machine and the electric fan stop steam turbine. (Electrical jump turbine chain has switch control)
