BREAKDOWN PHENOMENON CAUSE ANALYZING REMOVING WAYS
3. Run the machine, the red
lamp isn’t on, no output, the
fan is working.
1. Check all the connections
inside.
1. Check joint.
2. Check the control module,
drive circuit, drive module.
2. Check and replace.
3.Check the MOSFET, trans -
formers, rectification and con -
nections.
3. Check and replace.
4. Run the machine, the fan
is working, the pilot lamp is
working, no output.
1. Over temperature protection. 1.Stop working for five minutes.
2. Over current protection.
2. Close the machine for five
minutes and restart the machine.
3. The inverter parts are wrong
3. Measure the rectification
tubes one by one and replace
the same type components.
4. Pull off the socket of middle
board nearby the fan.VH-07
after closing the machine re -
start, the red lamp is on, be
sure that the individual MOS -
FET is damaged, meanwhile
check the components on
drive module.
1. The LED monitor has no
show, Run the machine and
has no any reaction.
1. Check the power supply
outside.
Check
2. Check the AC-380V input
and the air switch.
3. Check the DC-24V and the
supplementary power supply,
and the transformer of DC24V.
2. The LED monitor shows nor -
mal, the fan is working, the red
lamp isn’t on, no output.
1. Check the connections
and judge them.
Check
2.Check the control model
and drive model.
3. Check the MOSFET, main
transformer,rectification tubes
and the connections.
