]E"I.Ti�G7C <br /> Issued: 03/2012 Supersedes: 03/2010 <br /> Flygt FLS Sensor Family <br /> INSTALLATION <br /> The Float Leak Detector is usually installed in C/D pumps,3000 Series,at the bottom of the stator housing,on the top of <br /> bearing housing,bonded to it with an epoxy-based adhesive. It can also be used to check for water intrusion in the junction <br /> box for big pumps and hydroturbine generators <br /> When used with the MiniCASII supervision relay,the leakage sensor is connected in series with pump motor thermal <br /> switches,so only two wires are required to connect both leakage and thermal sensors.if a 068 sease f;s ala,..used,t <br /> TECHNICAL DATA, DIMENSIONS & PART NUMBERS <br /> Technical data <br /> • Signal:—8mA off-duty current,—36mA alarm current <br /> • Supply voltage: 12VDC <br /> • Max temperature: 90°C, lh <br /> • Test temperature: 115°C, I <br /> • Max duty temperature 70°C <br /> • Material: aluminum <br /> Dimensions <br /> • Length:27 mm(1.06 in.) <br /> • Width: 16 nun(.63 in.) <br /> • Height: 16 mm(.63 in.) <br /> Part numbers __ - <br /> • FLS: 518 89 02Float heak Deteeter, 4 82 62 00 <br /> E— <br /> F16S 10! 663 04-00 <br /> I ' <br /> TESTING PROCEDURES <br /> The FLS can be tested with a standard ohm-meter. <br /> The Float Leak Detector/FLS-20 resistance should be: <br /> • De-activated-about 1500 ohms; <br /> • Activated-about 300 ohms. �— <br /> Tl,. fte4i....4...7. ab 0 t 12 0 0 ,.L..,..... <br /> Caution: never apply more than 14VDC to the sensor-a higher voltage can destroy the sensor. <br />
