Polar 76em with error codes 84 and 86

[JamesDDP]

I am having an issue with our Polar 76 em where the clamp did not go down all the way and the machine gave error 84. When I turned it off and restarted, we received error 86. I checked fuse F4 which was blown and replaced it. The machine started up and went through measurements and appeared ready to cut. When we tried to cut, the clamp stopped short again and another error 84 & 86 as described above - fuse blown again.

It looks like one of the capacitors on the power board (all the way to the left) may have been overloaded as it is black like it overheated. Does anyone know if we might be able to replace this capacitor (and maybe the silver on under it) to repair the problem or what is best path forward? Where can we obtain a replacement board if that is the way to proceed?

Thank you in advance!!

Hello James,
Follow these steps and come back to us.

Most probably that was caused by an short cirucit or an over voltage. Check also the PCB traces, sometimes they blow also.

Hi Sir:

Test first the regulated Power Supply: PS + 5 AND PS +24 IN TOLERANCE.!!!!

Blessing.
