woodhead testers are small devices with testing abilities that include reverse polarity, open- ground, open-neutral, open-hot, hot-and-ground-reversed, hot-on-neutral, hot-unwired, ground fault circuit interrupter (gfci) functional and receptacle tension. woodhead ? testers perform basic-verification and multi- function wire testing with compact, simple-to-use devices that are a must for any toolbox ? electrical contractors ? inspection tools ? service tools plug-in enables a quick-read; go versus design no-go indication neotex ? rubber optimum resistance to the affects of construction heat, cold, abrasion and chemicals wide variety of provides customer convenience tooling capabilities testers features and benefits applications

www.woodhead.com f-13 test/control f technical information test and control assembly instructions pushbutton stations wiring of switches when a set of two pushbuttons is used to control complementary functions such as up-down, open-close, left-right, etc., the two buttons should be wired as shown in the diagram below to provide an electrical interlock. this electrical interlock method of wiring provides two primary benefits: ? it prevents the simultaneous operation of both functions, thus protecting equipment from damage. ? if a pushbutton switch should fail, depressing the complementary button opens the control circuit, thus providing an emergency stop. the switches supplied with this station are rated at currents substantially higher than those normally encountered in control applications. it should be noted, however, that electrical failures in associated equipment can cause currents to flow which far exceed even these high ratings. single-speed interlock applications circuit schematic for two single switches wired for interlock ( note: no = normally open; nc = normally closed) two-speed interlock applications super-safeway pendant station, 402x and 4032 series, two-speed contact ratings volts ac current horsepower circuit schematic 125 10 1? 3 hp, 125v ac 250 10 ? hp, 250v ac 4052 pushbutton station switch characteristics legends for 402x and 4032 series pushbutton stations legend series woodhead numbers order no. bridge crane close down door east fwd fast high hoist in lower left low magnet north no. 1 no. 2 no. 3 on open off out rev right raise south stop start slow trolley up west blank(2) 4020 71-4220 130203-1295 4052 31-5800 130228-0427 note: switches are ul listed. legends for 505x series pushbutton stations legend series woodhead numbers order no. off up left fwd north east open in raise start on down right rev south west close out lower stop 505x 505bc-l 130126-0009
