Re: CMOS Battery Failed VMX42 (2005)
Bloke
I have some odd things happening.
Tested again after reading your posts properly.
5 .01 V, 12,2 V, 24.2 V loaded and unloaded.
But now I have no optional keyboard but have main key board lit up and can move between window etc.
I need to be able to use the optional keypad to use the Function buttons so I can start it etc, the monitor has been changed at some time in the past.
So it is nearly there, but why has it all of a sudden decided to do this, is it because of removing and replacing the orange plugs???? but then why has it now stopped the optional keyboard??

The optional keyboard plugs into the edge of the CPU furthest away from you. It may be the plug has got disturbed during testing. Some of the machines had a small adaptor cable that plugged into the CPU and then had a larger plug about 6 inches away from the CPU.

Will check in the morning, getting a bit past bed time.
After the experience with what looks like dry joints , what is the best to clean them with?
Is electrical contact cleaner the go?
Best regards and thanks

That may help. Worth a shot!

As an aside, the machine keyboard functions are handled via that board in the middle of the rack with the yellow and red LEDs on. It is the Canbus Controller. It may have a badly seated plug to the top. It also handles the I/O from the toolchanger via that thin ribbon cable to the DCI/O backplane to the bottom of the I/O cards on the left.

Ok I will have a look there with all the ins and outs I may moved a few bits around and disturbed some things, although I have been careful.
Best regards

Re: CMOS Battery Failed VMX42 (2005)
There are three connecting blocks in the cabinet. Each has a 37 way D plug and a series of little terminals.
Locate Blk3 and connect a meter on ohms to terminal 29 and 0v. When the power button is pressed, there should be near continuity between the two points (it goes through a relay coil with a diode). If not, you may have a bad E-stop button or the cable to the head E-stop has a break in one of the wires to the normally closed side of the switch(es).

Hi Bloke
I will have to check tomorrow when the wife is home so I can get her to push the button, in the meantime I pulled the plug out and had a look all looks clean, gave it a clean anyway, refitted and turned power on, still no change so I thought I would push the E-Stop and see if that did anything, then I could here a clicking sound in the cabinet, had a look and found a red light flashing on and off?
Only way to get rid of it was to turn it off, could this be a overload, and it it have been going to earth?

it's going to be the relay for the red alarm light. Release the E-stop, press manual, reset servos and spindle, power then start to see if she clears...

Hi
Right what I found is that it happens when I haven't pressed the Manual button then pressed the E-Stop, when I press the E-Stop when in Manual mode it glows a steady Red.
So just never seen that before, but with the door open I could hear the clicking?

did you set the BIOS settings as per the Hurco document?

Hi
Yes I believe so, but will check again in the morning incase I missed something, looking at my notes there was a couple of things different and I am not sure now whether I changed them or not!

Hi Bloke
do you know which pin is 0V?
Can not find any decent electrical schematics anywhere in my information.
Checked all BIOS and parameter settings and reset to data supplied, restarted and back with more tool changer errors so reset with the parameters I noted down when I first checked, and errors disappeared so now back to the no Power On response.
It's like it is not telling a relay somewhere to fire up?

There is a restrictor valve for the spindle air purge inside the door on the head. You could reduce it very slightly and it would use less air or maybe change the parameter that lets the purge run for half an hour down to 20 minutes.
PM me an email address and I'll send a schematic for your machine.

Hello everybody! I have the same problem with the CMOS battery, I removed the battery to check it, find it dead.
But when I put again the same battery, I have a problem with the video signal, I don't have video.
Any ideas to solve the problem?
