Hello everyone.
We've got a problem with our cd74 2004 cp2000.
There was warning on screen "coater level not ok" andm Smoke started to come out of the A61 module (see picture). The module is located on coater unit.
Any idea what can cause it?

Hello
A61 is a 380VAC to 24VDC Power Supply and it can be found in all PUs, Delivery and Feeder. For the begining, disconnect the two plug with blue wires and switch ON the machine. If you see the LED are ON, then there is a short circuit somewhere on coating unit. But if the LEDs are still OFF, the module is broken.

Good luck

    Hi,

    Thanks for your answer.
    It looks like the module is seriously broken (see pictures)
    Can't find out where is shortcut on coater unit. It was working fine and then suddenly started to smoke. No problems at all before this.

    Yes, it is damaged. Unfortunately it's a common issue with these type and there is no possibility rather changing.

    Hi, thanks for replying.
    How did you connect these plugs on this supply?
