[Dsg-hallc_controls] UPS status

[Steve Lassiter]

Hi, 

The status for the HMS_UPS does not appear to be working. A 24V dc source is from the rotation rack is being feed into pin 12 on the UPS and returned by pin 13 to the I/O module rotation:3 ch11.data. The ground of the 24VPSU is fed into the group3 common block of the I/O module. 

If the ferrups UPS uses a transistor with reference to its internal 12V psu, then an isolation relay will be need at the UPS connection, as the two dc psu will have different grounds.
