olks - when building the new controls for my machine - i face a peculiar problem.
One of the 220v relays is getting heated up.
the relay is rated at 220V and that is supplied to it via a relay (used for estop) 24v - the 220v relay inturn switches on off the 24v timer which is used to bypass the 50-OHM resistor on the main supply to the supply transformer TR1
any ideas and help are welcome.
I will post pictures of my controller build soon.
otherwise follow my UHU controller build here -
