Tornado 300 Duplomatic Turret

[yarpo]

Hi,

We have a Colchester Tornado 300 with a 12 Tool Duplomatic Turret, with Fanuc O-T B.

It was running fine until last week.
The turret continued past it's designated tool, clicking as if the pin hadn't fired enough and flagged a "Turret overheat, turret unclamped, turret solenoid, 401 servo alarm"

We managed to get it going by backing off the solenoid capscrews, so the solenoid was sticking out by a few millimeteres. This got us away enough to complete the job.

We took the solenoid out and dismantled it, noticed that the insluation was a bit wet/slimey.

We've since replaced the solenoid with a brand new one, but are getting "1019 turret solenoid" errors.

If we back the solenoid off the turret rotates and locks in.
Is this a problem with the locking pin sensor?

Need this sorted asap, got a lot of work for this machine and can't wait for an engineer to "fit me in" in a few weeks time..... HELP!

Yarpo.

hi yarpo , you can try this.
Remove the round duplomatic cover from turret ,
in MDI mode command atool change ,
with the solenoid in place ,,
Using a screwdriver you must help the solenoid to lock in the right position , by pushing that locking pin
If you can do these several times then i will suspect you have a lack of voltage-current
from solenoid switching device ,

Thanks for the prompt reply cncatj..

I checked the voltage across the solenoid and I'm only getting 20volts, looks like this could be the problem.

Thanks again!

you have found the cause
Yarpo : How does your output pCB looks like ?

[yarpo]

Traced the fault back to the PCB. IC-1. It is constantly outputting 24v.
IC-1 also operates the chuck, but that is working fine.
Looks like we'll have to de-solder IC-1 and try and replace it, or buy a new PCB (expensive option!)

Hola tengo un torno Clausing Colchester STORM CNC 300, con fallas en el cambio de herramientas en la torreta DUPLOMATIC BSA200/ Series 20. Hace algunos cambios con pero después de 10 cambios de herramientas este falla, no bloquea la torreta. Ya seguí el procedimiento de ajuste pero aún a si sigue la falla la torreta tiene exceso de vibración al hacer el cambió, cuenta con 2 amortiguadores hidráulicos que no he cambiado, por qué no los encuentro. Me podrían apoyar un poco con esta falla?.
Saludos.

Yo tengo el mismo problema, cambié los shock absorbe y ya me hace cambios, pero solo en un sentido, en sentido anti horario. Cuando regresa el giro en sentido horario me falla de nuevo.
Alguien me podrá ayudar?

Check your sensors if they are OK I suspect you have a relay fault
