[Dsg-hallc_controls] Fwd: Adding the WRG

[Steve Lassiter]

Hi, 

Andy has made the hardware and wiring changes for the HMS vacuum signal and control. Now the signal and power cyling needs to be added to the HMS PLC code. I provided the code used for similar gauges used on the SHMS in a previous email. 

Thanks 
Steven

Hi Steve, 

Attached is the sheet that came with the dataforth module (I'll put the original in the storage room) and a boring description of the modifications I made to the wiring for HMS Q3's control rack to control an Edwards WRG (just like the ones on the SHMS). TLDR...The gauge's 24 V power is controlled by PLC slot 4 channel 3 and it's output (0-10 V) is read at slot 7 channel 11. Thanks. 

Andy
