Heidelberg GTO 52 run/inch problem

I have a 1981 Heidelberg GTO 52 newly set up in our shop, I haven't run
a Heidelberg in years so I'm hoping I am missing something obvious or could
use some points in the right direction.
The machine is getting power, however it will not run or inch, I checked I the
safety covers and the manual handle...all seem ok. If I press the paper stop safety
switch in and press the forwarding incher I can hear "buzz" when I press reverse
nothing. If I pull in the motor brake I can spin the cylinders freely so I don't think
the cylinders are binding up. Any thoughts?

 

Newly set up? Do you know it was running prior to disassembly? I would suggest you verify the motor leads are hooked up in the correct order, single phasing will cause that buzzing, but it will try breaker/pop fuse in short order. Check wires for solid connection at C1 and C2...TURN POWER OFF FIRST!

 

Thanks for the repsponse Junker, Yes the press was sold as running...although problem with delivery busted skid, had some trouble getting it off truck.
I went through the press this morning and found that the delivery trip switch was busted off, also buzzing sound coming from d75 contactor when
triggered manually. Checked C1 and C2 all wiring secure. I don't have any manuals for the press besides operators, could you tell me what d75 controls and
if its possible to bypass delivery trigger to check if the machine will run.
Thanks

 

If delivery pile limit switch casing is not damaged, you don't have to bypass it. I'll have to get a set of schematics, may not be until this evening. Don't know off the top of my head what d75 is for. Anybody else able to help quicker? Anyone...anyone.....

 

here is a pic

 

That switch casing doesn't look familiar at all. Possibly a non standard replacement? Is it the delivery pile low limit switch?

 

Yes correct, not sure if it is a replacement though, I assumed once the delivery
tray hits that spring button (piece laying on the floor in pic) it stops the press.

 

I'm certain it only trips feeder off, but worth a shot. Assuming it's a normally closed switch, nut the two wires together and see what you get. Should be able to get back to you on d75 soon.

 

d75 relay is in the circuit for the hand crank/perfecting changeover. Is the hand crank fully disengaged from gear? Is the switch button making when handle is inserted and breaking when pulled back?

 

yes, the handle is functioning correctly mechanically, however when I hand crank
the press the motor brake is not disengaging...

 

Limit switch b194 at crank should be closed when handle is out and d75 should be energized to ready that circuit. In turn, motor brake will energize when handle is inserted. Is this a perfector?

 

Check your 24 volt circuit, fuse may be blown? Matter of fact, check all your small secondary fuses and your large primaries.

 

HELLO..WHEN YOU CHECKED ALL THE SAFETY GUARDS DID YOU CHECK THE 2 SHEET TRIP UNDER THE FEED TABLE AND ALSO THE DELIVERY JAM SENSOR..
THE BRAKE IS 24v I THINK AND SHOULD DISENGAGE AS SOON AS THE CRANK IS PULLED OUT TO ENGAGE.I WOULD SUSPECT THE FUSES FIRST.CHECK ALL OF THEM.DOES THE MACHINE INCH/RUN IF YOU HOLD THE BRAKE OFF MANUALLY?
IF YOU NEED A DIAGRAM OR ANY OTHER TECH/SERV-INFO CONTACT ME ON pressfixt@gmail.com
MANY THANKS....

 

Tested all the fuses in the press and disconnect box all were good.
Here is a pic of the disconnect box wired in by our electrician.
Electrician cant touch the press (we are a school) I would have to hire
someone if I can't get this figured out. Already contacted one place to
check it out, just waiting to here back.
^not a perfector, checked all the safety trip switches again today.

 

You've not mentioned whether you have 24 volts...

 

Electrician installed disconnect should make no difference, outside of rotation. In which case, press would just run backwards. This machine not a brush shifter, but a variable speed pulley, correct?
