Hello Tyler, 

Can you you provide me the schematic for the HMS and SHMS UPS 25 pin status cable? 

Thanks 
Steven

Hi Steve, 



Attached is a pdf of the UPS monitoring routines with color-coded comments on the different parts. 



Best regards, 

Tyler

Hello Steve, 


This afternoon, Amanda, Pablo, and I put cables and terminal blocks in the rack with the PLC controllers' UPS on the second floor of the counting house. We put in the new terminal blocks to make it easier to add a second cable in the future if a hardwired signal to SHMS PLC is desired. This cabling setup will provide the 24 V signal indicating no fault with the UPS. 


Since you have suggested to leave the final wiring to Hall C technicians, there are two labeled cables with ends left free and taped. One cable needs to go to a 24 V power supply and the other needs to go to the PLC input channel. 


Attached is a photo of the rack and cables. The cable to the PLC is on the shelf above the PLC. The cable to the 24 V supply is on the floor. 


Also attached is a sketch of the wiring for the dsub-to-terminal-block adapter and cabling installed today. 


Once the input channels for each of the PLC are finalized, please let us know so we can update and give you the code to download to the PLC. 


Best regards, 

Tyler
