First, the intermediate frequency furnace before booting : 

Check the water circuit and circuit before starting each time. Make sure that all water pipes are clear and check the circuit for any abnormalities such as loose screws. 

Second, the intermediate frequency furnace starts : 

Turn on the power of the IF power cabinet. Press “Control Power On Button”, the control power indicator light is on, the main circuit switch is closed, the fault indicator is off, and the DC voltage meter should display negative voltage. Then slowly turn the power to the potentiometer, while observing the meter, the DC voltmeter indicates an increase. 

1. When the DC voltage crosses zero, the three frequencies of the intermediate frequency voltage, DC voltage and active power increase at the same time, and the middle frequency sound indicates that the startup is successful. The power can be rotated to the desired power of the positioner. 

2. When the DC voltage crosses zero, the three frequencies of the intermediate frequency voltage, DC current, and active power rise at different times and cannot hear the normal intermediate frequency sound, indicating that the start is unsuccessful. The power potentiometer should be turned to the minimum and restarted. 

Third, the intermediate frequency furnace reset : 

If overcurrent or overvoltage occurs during the operation of the equipment, the fault indicator on the door panel lights up. The potentiometer should be turned to the minimum, press the "Reset button" fault indicator light, then press the "main circuit closing button", and then restart.

Fourth, the intermediate frequency furnace shutdown : 

Turn the potentiometer to the minimum, press "Main circuit open" and then separate the main circuit switch, then press "Control power off". If the equipment is no longer used, the power of the IF power cabinet should be cut off.
