Fast shutter door inverter maintenance

Fast shutter door inverter maintenance

1, Check the fan inlet of the fast rolling shutter door frequency converter regularly to confirm whether the inlet is blocked.

2, Clean the air filter cooling air duct and its internal dust of the fast rolling shutter door inverter once a month.

3, Check regularly whether the screws, bolts and plug-ins in the fast door inverter are loose, whether the ground and phase resistance of the input and output reactor is short-circuit, and whether the conductor and insulator are corroded. If found abnormal, to promptly wipe clean with alcohol. Its maintenance cycle is at least once a year.

4, Regularly measure the stability of the voltage output of each circuit of the switching power supply of the fast rolling shutter door converter, and whether the contact of the contactor has ignition traces. In serious cases, the new contactor of the same model or larger than the original capacity should be replaced; Confirm the correctness of control voltage, sequence protection action test; Confirm that the protection display circuit is normal; Confirm the output voltage balance of the converter when it is running alone.
