Rj2 controller fuse F1 7.5 amp keeps blowing disconnected cp2 turn power on fuse blows disconnected cp3 turn power on fuse blows disconnect red wires off fan fuse blows disconnect cp1 does not blow but controller still wont turn on if I remove psu from backplane to have a look will I lose memory in controller any advise

Found this info may be what I was looking for ?????????? is it likely I had a power surge if so where would I find the VS11 surge absorber is it on the psu how would a short circuit occur if so is it likely to be only with in the psu itself or else ware on controller
Causes of blown fuses F1 and corrective action
(a) Short-circuit in the surge absorber VS11
VS11 is inserted to absorb surge voltage between input lines.
If the surge voltage is excessive or sustained, excessively high
voltage is applied toVS11 and a failure occurs in the short-circuit
mode, causing F1 to blow. If a short-circuit occurs in VS11, and
there is not spare part, the system is permitted to operate without
VS11. In this case, however, obtain and install a new VS11 as
soon as possible.
VS11 ordering number: A50L-2001-0122#G431k
(b) Short-circuit of diode stack DB11
(c) Short-circuit between D and S in switching transistors Q21 and
Q22
(d) Short-circuit between diodes D31 and D32
(e) The secondary power supply module is faulty :
If one of the causes (b) to (e) above is detected, replace the power
supply unit with a spare unit.
The codes for F1 is : A60L-0001-0245#GP75
Causes of blown fuse F3 and corrective action
The device connected to connector CP5 of the power supply unit may be
faulty. If no device is connected toCP5 or the connected device is normal,
the +24Vpower used in a printed circuit board connected to thebackplane
is faulty.
The code of F3 is A60L--0001--0075#5.0 :
Causes of blown fuse F4 and corrective action
The device connected to connector CP6 of the power supply unit may be
faulty. If no device is connected toCP6 or the connected device is normal,
the +24E used in a printed circuit board connected to the backplane is
faulty.
The code of F4 is A60L-0001-0046#5.0. -
I havent looked at an RJ-2 cpu board in awhile, but isn't the backup battery attached to this and not the PSU board? I would remove the VS11 first. Its a surge protector and sounds like a MOV (metal oxide varistor) device. Look at mouser electronics in the USA or really any electronic component supplier.
Here is a data sheet for the G431k MOV device http://www.mouser.com/ds/2/420/16-03-2391-713.pdf
They should cost less than $1 (one U.S.A dollar) and I doubt fanuc can supply tham anywhere near that cost. Fanuc didnt build the component, no reason to be slave to purchasing it from them.
It protects from lightning strikes and voltage surges. When a surge occurs that is higher than the threshold voltage, it goes dead short - sometimes permanently. Diode stack DB11 is probably a bridge rectifier.
Id start by removing the VS11 device and trying it again.
Let us know what you find out. -Eric

Thanks for the reply I have removed the psu board and found the VS 11 surge protector it is blown has a crack down both sides of it I will get hold of another one from electronics supplier as for the battery back up there is one one both on the psu and cpu I was hoping that the back up battery on psu was for a card reader wtich I don't have installed from memory there was spare battery in controller when I first got robot and I attached it to connector on psu hopefully it is not necessary to have one there. Hopefully I don't have to reload programs on robot I have no copys

For now you can just cut it out and power back up. If your fuse still blows, then there are deeper problems. No way to know about the programs until you power up.

Thank you for your help removed surge protection and re installed psu system now powers up and controller and robot functions correctly did not loose software.Can imagine it would have cost a small fortue to send away to be repaired .I have now got to get a copy of my software i have not been able to get the k floppy to function comunicate with controller i dont have a card reader slot on controller would it be practical to purchace card reader board and save programs that way i am still learning my way around and if i lose software im in trouble thanks again

Glad to help.
Can you elaborate on what trouble your having with Kfloppy? What operating system are you using on your computer and do you have the proper cable? Please describe how you are trying to make it work. Maybe there is a step your overlooking?
I wish the newer robots had the kind of documentation that the older ones had. The new robots are these magic 'black boxes' of mystery and no schematics are available. You barely get function block diagrams in the manuals.

Are you able to give step by step instructions or where can I find good instructions it may be me but the one that I used wasn't very clear. Possibly could be cable I did check it but I may have used incorrect pinout I read somewhere that there was 24 volts on one pin and to be cautious when connecting it to computer . I checked board rate etc set to floppy etc but were unable to get coms between units.I will try again Thanks Trev

I had trouble with KFloppy on anything but an old DOS laptop.

Here is a cable pinout for the proper communication cable. Not just any old db9-db25 cable works. I use a win7 laptop running a virtual machine program called VMware and I have a copy of XP loaded on it. I run the XP operating system and use Kfloppy from there with great success. As with modern hardware, the 9pin serial connector has gone the way of the dodo bird. You need a USB to serial cable. Again, not just any one will work. I use one by Quatech that works great. In the virtual machine, you need to cross patch the serial comm port in XP to what ever the physical comm port is for the connected cable. When I have a longer moment to write, Ill guide you through the process. Maybe Ill just make a new topic for everyone to read. For now, here is the cable you need..

Thank you I will make a new cable this weekend the cable I was using did not have jumper wires on each end I had only made cable with the wire running across I had miss read the diagram thanks again for every ones help.
-
Can you please tell me what the difference is between these two cables both are for kfloppy
-
Best I can tell it in the handshaking. I just used the one I posted last night and worked with no problems. I have also used the one you posted...so I am not sure.
