A little help please

Does the flashing #4 mean anything on the led?

Does the flashing #4 mean anything on the led?

Yes, it means at least one limit switch is tripped. Page 116 of the ALLIN1DC manual has a table of the codes. That manual has schematics and other things that might be helpful.

Ruled out power supply. This one had same specs just high max watts

That ATX (computer) power supply should only be powering the ALLIN1DC itself. Trace the wires going from the COM terminals on H11 to find out what supplies the digital inputs. Measure the voltage across the output of that power supply. If this is the only electrical cabinet for the machine and there are no other power supplies hiding somewhere then I would suspect that the small 24V supply board (above the E-STOP writing) powers the E-stop circuit and possibly the inputs. Disconnect power to the system and trace it out using continuity mode on the multimeter or by following the wires if necessary.

Yes the 24v power supply goes to The h11 com terminals.
What voltage should I be getting to h11?

[AllenM]

I am not getting any reading

I would expect to see 24V across the output terminals of the power supply (bottom right corner) if it is powered and working. What you will see at H11 depends on whether the COM terminals on H11 are connected to the positive or negative terminals of the 24V supply.

If the positive terminal is connected to H11 COM terminals then expect to read 24V from H11 COM terminals to power supply negative. Otherwise, if the negative terminal is connected to H11 COM then expect to read 24V from power supply positive to H11 COM.

If you are not seeing anything in those three measurements when you have power applied to the supply then the next thing is to determine whether the output is short circuited somewhere or if the supply is malfunctioning. Power down the machine and wait for the capacitors to discharge. Use DC volts mode to confirm there is no residual voltage then remove the two wires from the 24V power supply output terminals. Measure across the now open output terminals - if you see ~24V then it is very likely that you have a short circuit somewhere in the wiring. If you see nothing across the supply and you have verified that it has 95V - 130V AC input then the power supply is most likely faulty.

I gave up and called the service center, they will be out tomorrow. I am curious what he finds. I really appreciate your time and advice

[centroid467]

No problem, happy to help! I hope they can fix it up for you!

[AllenM]

You were correct, it is the 24v power supply

[centroid467]

You were correct, it is the 24v power supply

Glad to hear it is something simple to fix! You'll be back up and running in no time.
