CPR X HAD LTSS FROM ACR Y. SYS ERROR.

Narrative

I WAS WORKING CPR X INBOUND TO SCOTTSDALE; AZ; FROM FL330 TO FL240. IN CONFLICT WAS ACR Y FROM PHOENIX; AZ; TO LAS VEGAS; NV; REQUESTING FL280. I THOUGHT CPR X WAS ISSUED THE FERER 2 ARR AFTER DRAKE BUT WAS ACTUALLY CLRED DIRECT SCOTTSDALE AFTER DRAKE. I CLRED ACR Y DIRECT PEACH SPRINGS; AZ; TO GET RTE SEPARATION AND DISCONTINUED VERT SEPARATION AFTER I OBSERVED ACR X MAKE THE TURN. WHEN CPR X TURNED DIRECT SCOTTSDALE; I TRIED TO GET SEPARATION BY TURNING BOTH ACFT AND TRIED TO REESTABLISH VERT SEPARATION BUT THE ACFT WERE ALREADY TOO CLOSE. I DISCOVERED THE PROBLEM. THE COMPUTER DID NOT RECOGNIZE A PROBLEM UNTIL AFTER I WAS ALREADY TAKING ACTION TO TRY TO FIX THE PROBLEM. THE BIGGEST CONTRIBUTING FACTOR IN THE SITUATION IS A LACK OF AIR TFC CTLRS. EVEN THOUGH I FELT I HAD CTL OF THE SECTOR (UNTIL THE CPR X MADE A TURN I WASN'T EXPECTING) I WAS TOO BUSY TO READ THE FLT PROGRESS STRIPS. (AFTER THE EVENT WE WERE NOT ABLE TO FIND A FLT PROGRESS STRIP ON ACR Y WHICH I WAS SUPPOSED TO BE USING.) ANOTHER CTLR ON THE SECTOR (WHETHER FPL OR DEVELOPMENTAL CHKED OUT ON NON RADAR) WOULD HAVE BEEN READING THE FLT PROGRESS STRIPS AND TOLD ME I NEEDED TO ISSUE THE FERER 2 ARR. MY ERROR (THE ONLY HUMAN ERROR) WAS IN NOT ISSUING THE FERER 2 ARR. IF THE CPR X HAD FLOWN THE FERER 2 ARR THERE WOULD NOT HAVE BEEN A PROBLEM. ALSO; AFTER I IDENTED THE PROBLEM I TRIED TO GET VERT SEPARATION BY PUTTING THE CPR X ON THE (270) AND ACR Y ON THE BOTTOM (260) AND IT PROBABLY WOULD HAVE BEEN BETTER TO PUT THE CPR X ON THE BOTTOM. I STILL PROBABLY WOULD HAVE LOST SEPARATION BUT WOULD HAVE BEEN CLOSER.
