36 / 108 page ![]() 312 COMMUNICATIONS TRUSTED SINCE 1862 COPPER & DSL TESTING www.greenlee.com Wire and Valve Locator • Adjustable transmit power allows you to select the best signal for maximum performance • Transmitter’s high power output offers extended range and use on higher resistance wire paths that other locators can’t touch • Receiver provides both audible and visual indications of signal strength. • Lightweight receiver wand makes it easy for you to move along quickly to locate even the longest wire path • Rugged headphones block ambient noise and improve “feel” for the signal • Includes transmitter, receiver, headset, ground stake, and complete instructions • Battery-operated: (8) “D” Cells and (1) 9V SPECIFICATIONS Power Requirements Transmitter: (8) “D” Cell; Receiver: (1) 9V battery Battery Life Transmitter: 50 hours nominal Receiver: 100 hours nominal Transmitter Frequency 1748Hz Transmitter Power 750Vp-p 285Vrms Voltage Protection 120VAC/250VDC Construction Powder-coated aluminum housing in polyethylene case Case Dimensions 33.5" x 8.25" x 3.75" Weight 12 lbs. complete CAT. NO. UPC NO. DESCRIPTION 521A 86788 Wire and Valve Locator 521A-R 12623 Receiver HS-1 08695 Headset Locators Application Guide 1. 10,000 ohms and less–both ends isolated from grounds. 2. Does not locate the path–has to be predetermined and only in direct burial applications. 5,000,000 and less. 3. Transmitter connected to metallic shield. 4. Will trace coax providing the bOnd is in place at the remote end–will disrupt service. 5. No sorting (high RF bleeds) can trace coax if transmitter connected to braid. 6. Low frequency locators need a “path to earth” (dirt), 5000 ft. on an open conductor and 2500 ft. on a metallic pipe at 3 ft. deep FEATURE BLL-200 501 PE2003 508S 521A Trace concealed wiring in walls and floors • • Locate junction box relays and transformers • Locate switch gear • Find shorts to ground •2 •1 Trace wires in PVC (nonmetallic conduit) • • • Find opens in a circuit • Localize power and lighting panels • • • Operate on energized circuits • • • Operate on telecom circuits • • • • Operate on power circuits (600VAC) • Operate on unenergized circuits • • • • • Trace shielded cable • •3 •3 •3 Trace buried metal conduit Trace coax cable • •5 •5 •4 Auto gain circuitry for improved accuracy • AC voltage range 0-600V 0-240V 0-240V 0-240V 0-120V DC voltage range 0-300V 0-500V 0-400V 0-500V 0-250V Distance–receiver from transmitter 5,000 ft. •7 5000 ft. 1000 ft. •6 Transmitter battery (4) AA (8) AA 12V rechargeable (1) 9V (8) D Receiver battery (4) AA (1) 9V (1) 9V (1) 9V (1) 9V 7.
