UPS on a pick and place machine

UPS on a pick and place machine | 4 August, 2003

When a UPS is used on pick and place equipment is it setup to continue to run the entire machine or is it just keeping the computer(s) powered up? How long will the UPS typically supply power to the machine?

We loose power all the time. So, we have a UPS the size of a four of cases of beer on our telephone system.

On placement machines, most people opt for an orderly machine shut-down, rather than completing the program, but you can do it either way. It just depends on how much money you want to spend versus loosing that portion of the machine.

Here's a calculator to get an angle on sizing your UPS http://www.suttondesigns.com/fnoble2/349.htm

From this calculator you can estimate the size UPS you'd need for each option.

UNIX machines remember the last component placed before the power doinks-out. Coo, eh?

All of our PNP machine run on UPS back up. Though our machine controller is Dos and failry stable it is integrated with Windows NT who does not like to be prematurley shut down.

We get a window of about 4 hours from the UPS. Remember this is just on and not running- time enough to do a proper shut down.

The UPS we use is APC Smart-UPS 5000.

It looks like I could setup a UPS on this machine one of two ways. The first would be a 3 phase, 208V UPS in series with the machine (sounds big and expensive). The second is a single phase 208V UPS to just the 2 computers.

I have a safety concern with the second way, if the machine is powered down and the lockable safety switch is turned off the PC's and a couple related devices will still be powered up by the UPS. Is it allowable to have a second switch or must everything be through one switch?

Our machines are Single phase 220v. The big honkin' hubble plug goes right in the back of the UPS for the whole machine...no seperate lines for the PC's. Also the UPS is dedicated just to the machine even though it has a 120v Recepticles.
