Precautions for Turning the Medium-Frequency Furnace On and Off
Oct 18,2020
If you encounter any issues with the ignition of medium- and high-frequency sensors, please click the link to find a solution or directly contact 18365639009 for an industry-leading solution.
One, Medium-frequency furnace Pre-boot check:
Before each start-up, check the water and electrical circuits. Ensure all water pipes are unobstructed and inspect the electrical circuits for any abnormalities, such as loose screws.
II. Medium-frequency furnace Power on:
Turn on the power supply to the intermediate-frequency power cabinet. Press the “Control Power On” button; the control power indicator light will illuminate, the main circuit breaker will close, the fault indicator light will turn off, and the DC voltmeter should display a negative voltage. Then, slowly increase the setpoint potentiometer of the power supply and observe the ammeter and the DC voltmeter readings as they rise.
1. When the DC voltage crosses zero, the three-phase intermediate-frequency voltage, DC voltage, and active power all increase simultaneously, and you’ll hear an intermediate-frequency sound, indicating that the startup was successful. You can then adjust the power supply to the level required by the locator.
2. When the DC voltage crosses zero, if the three-meter intermediate-frequency voltage, DC current, and active power do not rise simultaneously, and you cannot hear the normal intermediate-frequency sound, it indicates that the startup was unsuccessful. The power supply potentiometer should be adjusted to its minimum setting and the system should be restarted.
Three, Medium-frequency furnace Reset:
If overcurrent or overvoltage occurs during equipment operation, the door panel fault indicator will light up. The potentiometer should be adjusted to its minimum position, then press the “Reset Button.” Once the fault indicator lights up, press the “Main Circuit Close Button” again and restart the equipment.
4. Power off:
Turn the potentiometer to its minimum setting, press “Main Circuit Switch Off,” then disconnect the main circuit switch, and finally press “Control Power Off.” If the equipment is no longer in use, disconnect the power supply to the intermediate-frequency power cabinet.
