- Sep 03, 2018 -

Fault 1: power indicator light is not bright.




Terms of settlement:




1, check whether the power cord is output.




2. Is the main gate tripping?




3, whether the fuse is burned or the breaker is tripped.




4, does the transformer have input and output?




Fault two: no magnetization.




Terms of settlement:




1. Is there a voltage display on the voltmeter with a display value of 110V~130V?




2. Check the fuse and related lines.




3. Check whether the current relay is working normally.




4, check whether the bridge is burned out.




5. Press the magnetizing button to see whether there is work in the magnetizing AC contactor.




Fault three: stroke motor or wheel motor can not work.




Terms of settlement:




1. Is the motor damaged?
