Tight Operating Tolerances. Rugged Construction. Increased Contact Life. High Reliability. 7790B Multi-Voltage Control Made in the U.S.A.</p><p>The Fisher Pierce 7700 Series OutdoorLighting Control combines a history ofreliable performance with the designand manufacturing techniques of the1990's. Capitalizing on over 40 yearsof experience in the manufacture ofinstant-response, electromagnetic relayoperated photoelectric controls, FisherPierce has completely re-engineeredthe photocontrol concept, as well asdesigned and installed a state-of-the-artautomation system for manufacturingthese advanced outdoor lightingcontrols. The superior performanceof the Fisher Pierce Series 7700photocontrol places it a step aboveall other controls on the market today.</p><p>To fully evaluate the 7700 photo-control, a thorough test program wassuccessfully completed. This programencompassed design and life tests wellabove current ANSI C136.10 1988standards. Individual components andassemblies were carefully analyzedfor manufacturability and repeatability.</p><p>In addition, pilot production units weretested and evaluated by selected utilitycustomers. Over 6,000 controls werefield tested at the most severe appli-cation sites by 40 utilities. Utilizing thefeedback from these 40 utilities, thisconcurrent engineering project, whichcommenced in April 1990, confirmedthat the Fisher Pierce Series 7700 photo-control mean time to failure is improvedby a factor of approximately 5 times thatof competitive photocontrols. As of thedate of publication of this brochure,10.5 million Series 7700 controls arein service.</p><p>The Series 7790B multivoltage photo-control circuit design has been modified,resulting in a 50% reduction in controlpower and improved operation perform-ance over its entire voltage range(U.S. patent pending).</p><p>Series 7760 control with standard surtace-passivatedphotocell and standard open-type expulsion arrester.</p><p>Series 7760-EPS control with hermetically sealedphotocell and deluxe expulsion arrester.</p><p>Series 7790B multi-voltage (WO-300V) control.</p><p>Electromagnetic Relay DesignThe Series 7700 photocontrol designincorporates an electromagnetic relay(U.S. patent 5,132,596) which offersseveral key advantages over traditionaldesigns. Its unique unitized designassures consistent performance andmanufacture, while improving theruggedness and durability of the photo-control. This self-supporting unitizedrelay configuration effectively eliminatesshock damage from shipping andhandling.</p><p>The relay design also assures veryprecise adjustment of the relay contactgap and armature gap, significantlyreducing relay contact bounce, chatteror hum. Relay operating characteristicsare determined through adjustment ofthe relay yoke and magnetic coreassembly by a computerized visioncontrol system. Contact adjustment isprecise and does not require manualbending and deformation of contactbrackets a common practice in otherphotocontrol designs. A single precisecoil spring is used in place of the paral-lel flat springs common on most photo-control relays to improve ruggedness,and provide consistent contact force.</p><p>Cadmium Sulfide PhotocellSeries 7700 outdoor lighting controlsutilize specially processed cadmiumsulfide photocells developed exclusivelyfor photocontrol applications. All FisherPierce photocells are produced utilizingour own highly automated cell manufac-turing facility. Gold/platinum electrodesand high temperature firing in a nitrogenatmosphere assure a long stable cell life.</p><p>The Series 7700 standard, surfacepassivated photocell has proven to bemore than adequate for the vast majorityof installation.</p><p>An optional, polycarbonate, hermeticallysealed photocell (MIL-STD-202D,Method 112A, Test Condition B) is avail-able for use in adverse environmentswhere high concentration of airbornecontaminants are present.</p><p>Fisher Pierce 7700 Series patented unitized electro-magnetic relay.</p></li><li><p>ConstructionEach Series 7700 photoelectric controlis constructed on a 3" wide heat-resis-tant thermoplastic base. This advancedUL-recognized material is highly stable,rugged, and durable. The wide cross-linked polyethylene gasket assuresmoisture-proof sealing with the recep-tacle. All Fisher Pierce photocontrolsare equipped with solid brass contactlegs for positive socket mounting andcool, trouble free operation.</p><p>Load current transfer between thephotocontrol terminals and the internaloperating components is made directly.Most low current internal connectionsare made through the use of special,snap fit connectors to improve dura-bility, consistency and quality. Manualsoldering and riveting operations areminimized.</p><p>HousingStandard Series 7700 controls utilizedurable, easy to handle ANSI color-coded polypropylene housings, whichoffer high impact strength and excel-lent ultraviolet resistance. A clear,UV-stabilized window allows directional(north oriented) viewing. These hous-ings provide flame retardance andimpact resistance in full compliancewith UL and CSA requirements. Anintegral barrier for the standard open-type arrester prevents damage to therelay and photocell from flashoveroutgassing or debris resulting fromlightning arrester/surge suppressoroperations.</p><p>Surge ArrestersLuminaire and photocontrol life isgreatly extended through protectionprovided by surge arresters. FisherPierce offers several types of surgearresters, which can be specifieddependent on the protection require-ments of the application.</p><p>a) Standard Arrester An open typeexpulsion arrester design whichmeets all ANSI requirements,for use in light to medium dutyrequirements. Specify arresteroption "S".</p><p>b) Deluxe Arrester The industrystandard in photocontrol surgeprotection, this expulsion designexceeds all ANSI requirements.The enclosed arrester designprovides tightly controlled voltagespark-over, power follow currentlimiting, and arc quenching fromDelrin insulator outgassing/vented blow-out. Specify arresteroption "E".</p><p>c) Deluxe Arrester (Special WiringConfiguration) For applicationswhere very high isokeuronic levelsexist, the special wiring configura-tion limits the maximum voltageacross the coil and photocell. Thisoption is available only with thedeluxe arrester.</p><p>d) MOV Surge Suppressors - 160 joulemetal oxide varistor (MOV) surgesuppressors are also available whenspecified. Please consult factory forfurther information.</p><p>Time Delay OptionA time delay option is available forthe basic 120V and 240V Series 7700designs. This special feature preventsfalse lamp turn off from transient light;yet allows the control to be "glovetested" instantaneously during daylighthours (unlike thermal photocontrols). Tospecify the time delay option on Series7760 and Series 7770 controls, add thesuffix "TD" to the catalog number. Con-sult factory for time delay test method.</p><p>Quality ControlEvery aspect of the Series 7700photocontrol manufacturing process isperformed under the strict supervisionof the Fisher Pierce Quality AssuranceDepartment. Inspection and test proce-dures include: Incoming inspection of all raw</p><p>materials and components. Statistical Process Control (SPC) of</p><p>all key product or process character-istics ensures "parts per million"quality levels.</p><p> Automatic testing and computer-aided grading of each photocellwhich ensures accurate, stableoperation.</p><p> Final electrical testing and visualinspection prior to packaging, includ-ing automated calibration and testingfor turn-on, turn-off, and differential.Computer printout of productioncalibration and test results providescomprehensive documentation ofconformance to your requirements.</p><p>Also available is the Fisher Pierce SkyScanner omnidirectional, translucenthousing, with zenith sensing, which maybe desirable in applications where highambient light levels or unusual lightpatterns adversely affect conventionalnorth-oriented controls.</p></li><li><p>SpecificationsRATED VOLTAGE</p><p>7760 Series 105-130V, 50/60Hz AC (120V Nominal)7762 Series 105-130V, 50/GOHz AC (120V Nominal)*7770 Series 200-300V, 50/60Hz AC (240V Nominal)7772 Series 200-300V, 50/60Hz AC (240V Nominal)7790B Series 105-285V, 50/60Hz AC (multivoltage)7792B Series 105-285V, 50/60Hz AC (multivoltage)*7793 Series 250-400V, 50/60Hz AC (340V Nominal)7794 Series 400-550V, 50/60HZ AC (480V Nominal)'unit includes deluxe arrester with special wiring contiguration</p><p>RATED LOAD 1000W/1800VA max., SPST, N.C. 1000W Incandescent Load 1800VA Mercury Vapor, High Pressure</p><p>Sodium or Other H.I.D.
