Thread: FP4 dialog 2 issue

Hello,

i've a problem with my fp4nc

The machine was on, but was not working on it.
When i came back there was a FP00 error message.

When i shut it down en restarted it. My y-axis dissapered on the display.

Opening the electric cabinet is see that the green ligt of the y-axis on the 038030 is off, i switched these cards from another axis but no result..

Where should i look further NZP55???

Leon.

Yes next swap nzp boards in the operators console, you must also set both sets of DIP switches.

Write the switch settings for the Y axis in slot vg2 then write the settings for x VG1 change switches for the axis you wish to change with and see if you move the problem.

If not it is probably dirty y axis scale or the lamp in the scale is bad.

Regards
DD

I had that happen just because of bad connections in the scale reader cables, where they plugged together. Unplugged them, reconnected them and restarted the machine, axis is back on screen.

Problem solved..

When i dismounted the cover off the cabinet to reach the cards en started up the machine to check or all cards, the axis came back on the screen.
I shutt off machine an checked all connections.
There were some which where not complete connected.

Thanx for the help.

I want to plan some maintance to the machine in the vacation which are important parts to check, replace.

Batteries, brushes, cleaning scales. some relays onstock.

Dont'want unplanned down-time. Machine doesn't run much but has to work when i need it.

Yes the scale connectors if not oriented correctly can have coolant and oil get into them.

I always make sure the female side of the connector is on the top mounted vertically so that the female pins do not fill up.

'My amplifier board died 2 days ago.

Some blown transitors

It's fixed now. retighten the srews op the transitorsboard.
It can cause defect on you cards

For my curiosity...were these the power type transistors that are screwed to heatsinks (with white conductive grease in between) or just random transistors on the PCB ?

there were three BUX48 transitors that died.
Yes they are those transitors screwed to the heatsink, due the heat srews can loosen a little bit so the power can raise and let the transitor fail.

We also noticed that capacitors when getting old are losing there chararistics.
So we replaced a lot of capacitors on different boards because they can cause faults in the future
