Rack 1 – Electronics Bay
Rack 2 – FE Rack (Receiving area)
Continued with troubleshooting of the EY rack temperatures. On May 4th, (alog 69322), we swapped the field rack 1 and rack 2 cabling on the End Link Chassis. Issue followed field cabling not Beckhoff channel. This morning I reverted the cable swapp and moved cables from ports 1&2 to 3&4. Internal cabling from rear panel to EL3202 terminal was re-wired.
All connections on both temperature sensors (RTP PT100) were re-landed to make sure all connections were making solid contact. A new field cable and temperature sensor was staged in the electronics bay incase it is needed for more troubleshooting.
The M12 connectors (ports 1&2) were replaced on the End Link Chassis. The field and internal chassis cabling was moved from ports 3&4 back to ports 1&2.
