Air dryer current too high trip (overload protection)

Failure situation: The air dryer trip failure indicator indicates that the equipment cannot be turned on. You need to manually reset the overload relay before restarting.
Cause one: The unstable on-site power voltage causes the air compressor and fan motor current in the equipment to fluctuate greatly.
Cause two: The air compressor is stuck inside, resulting in excessive starting current.
Cause three: The air compressor starting capacitor is damaged.
Cause four: The air compressor overheating protection is damaged.
Cause five: The power distribution wires are loose, causing poor contact of the wires and causing excessive current.
Cause six: The equipment circuit has a short circuit.
Cause seven: The contact of the AC contactor is poor, resulting in excessive current.
Cause eight: The thermal overload relay current is set too low or damaged.
Reason nine: The air compressor is turned on and off too frequently.
