Elimination methods
Recovery after the 150s
Check the communication connection
Recovery after the 150s
Check the measuring voltage, check
frequency conversion board hardware
Check whether current return wires
connected motor
Check and adjust the current
measurement
Check the input voltage measurement
Check the input voltage measurement
Check the input voltage measurement
Check the input voltage measurement
Check and adjust the current
measurement
Check the communication connection
Check whether the unit is overloaded
Check the PFC switch tube short circuit or
not
Check and adjust the current
measurement
Restart the unit after multiple power
failures, if the fault still exists, replace the
compressor
Check and measure the voltage
adjustment
Check and adjust the current
measurement
Check or change the temp. sensor
