5. Initial inspection
Before checking trouble shooting,must check the outside of power source,check the fuse,IGBT module,diode module
and PCB parts whether damaged.
1
、
Turn off main switch,shut off power source.
2
、
Check the 4 fuse back of machine whether fused.
3
、
Connect main switch,measure any two phase of the three phase inlet interface voltage,any two phase voltage shall as
same as power supply voltage.If found problem here,turn off main switch,check inlet power cable circuit.
3
、
Take out the top cover and two side covers.
4
、
Check the inside power source,ex. PCB whether have color changes as burned,or whether parts have been explored.If
found these parts or module have obviously phenomenon,shall replace all broken parts before do any test.
6. Air filter cartridge replace
Recommend users regular replace air filter cartridge,the steps as follows:
1
、
Cut off all power supply and disconnect the air tube to air filter.
2
、
Strike the filter cup.
