Just picked up a used Tornado 200 from a running shop. We are ready to power it up and one of the manuals says to check phase of wiring. Is this unit phase dependant perhaps to drive a hydraulic motor the proper direction? The manuals I have do not cover this topic.
Thanks,
Tim

I have Clausing storm 80 the hydraulics are phase dependent . On mine the fan cover for the hydraulic motor has has a red arrow sticker indcating with way the motor should turn. Stick a piece of paper in the fan and power up the machine then you can tell witch way the fan is turning. If its wrong it will shortly trip a breaker and throw up an alarm.

Also behind my machine not sure on yours theres a panel on the bottom next to the coolant tank . Behind it there is a transformer it has setting for different voltages 220, 230,250, 480, set it to your voltage.

Thanks, I found the arrow on the fan this morning and checked rotation, its ok. Unit was connected to 240 3ph which I have. I turned the control on and I get the Not Ready error, 401 VDRY velocity drive off error, lost pressure error, and turret overheat error. Reset doesn not clear any of them. I tried contacting the prev owner but he was not available. Hyd fluid shows up on the dip stick, but at the very bottom. The hyd do not come on when I push the control ON button. There is a relay that kicks in when I push the ON button, but turns right off when I release it, so that tells me there is another fault somewhere I need to clear. I am by myself and have no elec schem so I can't see what relay / unit is coming on when I have the ON button depressed.

Thanks,
Tim

I don't know what to tell you on that one . Have any of your breakers in the cabnet tripped. Tuesday call Clausing they have always helped me.
Clausing service 1-513-745-2222.

Hey thanks for the links, I have not been on the PM forum lately. I am going to run through the basics on incoming power just to eliminate that. We did move the machine from another location and I checked the boards and connections. I did not remove and re-seat any boards, just pushed them a bit. I've got the service number and contact from prev owner, but normal people are on vacation right now......
Thanks again,
Tim

Talked with Clausing tech sup today and he said it was like finding a needle in the haystack....So, prev owner stopped by yesterday and said hyd pump is not coming on. He switched positions of three relays behind the panel disconnect but that did not help. Power comes into the main 100 amp disconnect and goes from there to a contactor K10 and to the transformer under the bed. The main contactor is not coming on and I can not see the ID numbers on the transformer under the bed to see how it is connected.
When I turn the power switch on at the door, K13 contactor closes. This runs to the motor that has a belt to the spindle. The fan on the end of the motor runs. When I check power on leads UWV to this motor, I get no reading. Zero. No AC, no DC. How does the fan run? Contactor K10 is not on. This is the main contactor under the 100 amp breaker. When we push the green control power button on the control panel we get 1022 Turret overheating, 1027 Pressure lost, and 401 Vdry (off). The power supply module has the -- not ready bars, the Spindle Amp has flashing -- bars, and the Servo Amp has --not ready bars. I did remove the back covers and manually moved the spindle and slide back and forth a bit. I have not been able to manually move the turret yet. Any ideas?

Hi HMC , We have a machine like yousr down here, so here's my suggestions:

When this E-stop boards fails you can be sure if the power on the machine stays on as long as you keep pressed the green button , you can even send all axis to home posit. , have you tried this ?

[hmc710]

Hey cncatj, thanks for the reply. I have held the green start button on for a bit but I did not want to do any damage. Yes, things come on when I hold the button and shut off when I release it. I have not looked to see what relays / starters come on while I hold the button in but we can check tomorrow when I have another guy here. What would be the procedure, I am brand new on this machine. Thanks

[cncatj]

Also the 3 relays on that , A8 board are :
POTTER BRUMFIELD R10-EX6 - V430 24 VDC
hope this helps !!

[hmc710]

Prev owner said they were all "brand new" and we switched positions with them then tried ch 3&4 also. Frustrating bringing in a running mach that does not run..... Should I just go ahead and change our the relays or the whole board as was suggested earlier to eliminate that possibility?

[cncatj]

HMc , check this also:
The crash sensor mounted on the base of the turret , is activated ?
is a plunger swithch
Normally it has not to be !!
so first of all make 100 percent sure it's not activated

[cncatj]

HMC I would first make sure the E-stop board is the problem !

Also, do you have wiring diagrams ?

[600Service]

cncatj has hit the nail on the head!

If the machine stays on when the button is pressed in then the problem is the crash switch as per previous messages.

[hmc710]

Thanks cnc & 600 for the replies!

I found what I thought was a proximity switch at the lower right hand side of the turret (as I stand in front of the mach) and there is a swiveling lever by it. Perhaps this is the plunger you are talking about and not a proxy switch? I will check it when I get back to the shop. I remember turning the lever but did not see any plunger.

No, I do not have wiring diagrams, I am was waiting for Clausing to call back so I'll check in with them also today and see if I can get one coming.

[hmc710]

OK, there is a plunger at the back of the turret mounted to a plate. The plate has a small bar that rotates on back side. The turret has a black plate bolted to it but one of the bolts is missing. This would allow the black plate to rotate down and hit the tail stock if the turret came down, which would rotate the black plate back up to the plunger. The plunger, however, does not stick out far enough to engage the black plate. It may touch the plate slightly but that's it. I can push the plunger in about 1/8". SO, is the plunger supposed to be in or out, is this the crash switch, and what tells it it is crashed?
Thanks,

[600Service]

Yes, that's the crash switch.

If it's set correctly a 4thou feeler gauge should NOT trip it but a 6thou guage should.

If you let me know the wiring diagram number from the plate I can send you a circuit diagram. It will be something like C2-040.

[hmc710]

I let the black plate hang down and pushed the plunger in a couple times then turned power on. Unit powered up! Thanks guys! The control screen came up it flashed the X Y coords then alarmed out 1027 Lost Pressure and some relays kick out. Oil level shows up on the bottom of the dip stick, but only about 1/4". I put some hyd fluid in to check, and still get the Lost Pressure alarm.

H.
The rotation on the hidraulic pump motor should be in the arrow directions,
if you go behind the machine you will se the hidraulics motor , with a pointing arrow on top
ours turn CW , if you stand , behind the machine ,
If you found rotation wrong , then you have to swap 2 incoming main lines ,

this will cause also to reverse , spindle fan rotation ( The one below the red cap)

[cncatj]

At this point , with the right phasing , no matter if E-stop board is wrong ,
like i told you , as long as you keep green power button at machine boot-up
you should be able to jog axis, rotate turret & also , the hydraulic pressure shoud be present ,

H.
Glad to read your result ,
Another happy ending

Good luck !!
