Transformer Taps

[sccrcoach]

Where can I find the transformer tap for a RJ3 controller?

Usually the transformer tapping in FANUC is an optional feature depending on your geographical location.

Usually this can be found at the foot of the controller (closer to the transformer)

thanks...just trying to figure out why I keep blowing F1 as soon as I power on ...

Just to give us a reference.

Shut the power off
Open the cabinet, look behind the disconnect switch on the back panel
         Do you see all the high voltage wires (black ones)
         You should see the 3 going to the bottom of the disconnect
On the other end (Back panel) are they going to LA or LB

Check that out and write back

Somar,  The rj3 controller is the two part kind witht the operators panel and disconnect on top and the controller on the bottom...do I check behind the disconnect on the top part?

[Fabian Munoz]

Yes,
I dont have that type of controller in the shop, but they should be very similar

I just want to have a reference point with your troubleshhoting

[sccrcoach]

I will be at work in about an hour then I will write back

I checked the complete controller and could find no taps....

Sorry I wasnt very specific
when I said "On the other end (Back panel) are they going to LA or LB" I wasnt referring to the actual transformer taps, I was referring to the connector that goes to the transformers taps
