Power Source 360-ASX

[Heldo]

Hi!!!
We have a Power Source 360 - ASX from Pacific Power, and in one of our tests in laboratory the source entered in SHUTDOWN MODE, the manual of the product says that in this occasion we have to wait the causes of the fault  be extinct. But we are waiting for more than 3 days and the source is until in the SHUTDOWN MODE.
Someone can help me with this problem?
Thanks.

What have you done to remove any possible causes of the fault? Did you remove the load? Could it be drawing too much current? Is there an error query that you can run to see what the instrument reports as the fault? Simply waiting for a couple of days doesn't seem like a very good way to determine what caused the fault.

Dear Dennis Knutson,

Thank you for reply my question!!!!
The problem is when we are using the source to supply a induction motor, 1.5 cv, it (The Motor) presented an unexpected behavior, so I stopped the experience, from the software, after some time the power source entered in Shutdown mode, in the manual we find one of the possible causes, over temperature, something like that woud be caused by the excess of current and the Relay entered in operation.
If you know some command to apply in the software or in the power source to disarm this Relay I will be very grateful.

Cordial

Heldo.

Aside from the *RST command, I wouldn't know what else to try. It has been a long time since I've used a pacific power supply and I don't remember if that works or whether you need to cycle power on the instrument. I had a look at the driver and there is a :SYST:ERR? command. Have you run that to see what the instrument reports?

Hi Heldo,

A temporary (Over Temp) condition can be cleared by manually cycling the output enable switch Off and then On.  If the the Shut Down persists, there may be an internal failure our other problem other than temperature.   Check to see if you are applying the correct input voltage (i.e. 208V, 3 phase) as indicated on the system ID label.  If the voltage is correct, and you still cannot clear the shut-down, please feel free to contact the factory with the complete model number and serial number of the unit.  Send your information to sales@pacificpower.com.

Hope this helps,

Mitch

The cause for SHUTDOWN indicator, if it does not recover, might be a blown fuse in the cooling blowers circuits. These fuses are internal to the power supply.

However, be aware that it is very DANGEROUS to try to replace them. The components are very tight and you may get hurt.

Use severe electricity caution rules when attempt to repair it.

Good luck.
