We have a hot glue pot and hot glue hoses and and hot glue nozzle ( all of them have heater elements in them ) machine that glue box flaps together on a product box
One note the tech support person said that the glue used was a possible cause this situation to back feed voltage as well ( I personally have my doubts about this but it would depend on what this glue is made of )
That the fuses blew on the controller board (switching power supply board section ) but did not blow the heater fuses so I put new fuses and it blew the transistor on the controller board blew apart called technical support and was told that one of the heaters RTD temperature sensor or more than one of them had shorted to the heater element and was back feeling to the controller board
Now to me this controller board has some design issues for this to happen am I wrong with this idea
