QM46-2

My QM46 plate warning is flashing and compressor does not come on. Tested the compressor and it appears no power is getting to it. The press doesn’t start just the plate warning light flashing. Any suggestions?

 

Hi Sir:
I see you have problem with the power supply : a) No compressor b) No running machine
1) Measure in SVK2 board fuse F1 if is o.k or open with continuity DMM(digital multimeter).
2) In SVK2 board measure 32Vca plug X7 terminals:9+10=32Vca
3)If there 32 Vca in Plug X7 go and measure the Fuses+F3(c.breaker or Thermal Swithc) +F4 +F6 , they transport the Voltage for 110Vac. to the Compressor.
