Cpr jet climbed through altitude occupied by another cpr jet with less than standard separation. Approach control ARTS was inoperative, but primary and secondary radar was working. Reporter blames lack of ARTS data tags as the cause of this incident, but he should have had flight progress strips to show information on.

Narrative:
Aircraft X departed a satellite airport and called flo approach control for an IFR clearance. Flo radar idented the aircraft and issued the IFR clearance. ZJX (the center overlying flo) called and issued a climb and heading for aircraft X. The flo controller issued the relayed instructions to the climbing aircraft. Those instructions resulted in the aircraft 'climbing through' aircraft Y. Flo did not catch the conflict because flo had been operating in a 'non ARTS' mode, using only primary and beacon targets. The ARTS program was removed from service for routine maintenance. Removal of radar or secondary radar, or ARTS or any other component of the air traffic system during live traffic should not occur if other options are available. The FAA now routinely removes equipment from service for routine maintenance to save overtime funds that would be used to do this work when the facility is closed. This situation, as per the example above, causes unsafe sits.
Original NASA ASRS Text
Title: CPR JET CLBED THROUGH ALT OCCUPIED BY ANOTHER CPR JET WITH LTSS. APCH CTL ARTS WAS INOP, BUT PRIMARY AND SECONDARY RADAR WAS WORKING. RPTR BLAMES LACK OF ARTS DATA TAGS AS THE CAUSE OF THIS INCIDENT, BUT HE SHOULD HAVE HAD FLT PROGRESS STRIPS TO SHOW INFO ON.
Narrative: ACFT X DEPARTED A SATELLITE ARPT AND CALLED FLO APCH CTL FOR AN IFR CLRNC. FLO RADAR IDENTED THE ACFT AND ISSUED THE IFR CLRNC. ZJX (THE CTR OVERLYING FLO) CALLED AND ISSUED A CLB AND HDG FOR ACFT X. THE FLO CTLR ISSUED THE RELAYED INSTRUCTIONS TO THE CLBING ACFT. THOSE INSTRUCTIONS RESULTED IN THE ACFT 'CLBING THROUGH' ACFT Y. FLO DID NOT CATCH THE CONFLICT BECAUSE FLO HAD BEEN OPERATING IN A 'NON ARTS' MODE, USING ONLY PRIMARY AND BEACON TARGETS. THE ARTS PROGRAM WAS REMOVED FROM SVC FOR ROUTINE MAINT. REMOVAL OF RADAR OR SECONDARY RADAR, OR ARTS OR ANY OTHER COMPONENT OF THE AIR TFC SYS DURING LIVE TFC SHOULD NOT OCCUR IF OTHER OPTIONS ARE AVAILABLE. THE FAA NOW ROUTINELY REMOVES EQUIP FROM SVC FOR ROUTINE MAINT TO SAVE OVERTIME FUNDS THAT WOULD BE USED TO DO THIS WORK WHEN THE FACILITY IS CLOSED. THIS SIT, AS PER THE EXAMPLE ABOVE, CAUSES UNSAFE SITS.
