2 Heavy-Duty Brakes Shoe Brakes Magnetically Operated October Size GH0 Magnetic Shoe Brake Product Description The GH0 Magnetic Brakes comprise a complete family of heavy-duty brakes for use on cranes, hoists and other machinery. They meet specifications of AISE Standard Nos. 6 and and are available in seven sizes with torque ratings from 0 to 9000 lb.-ft. The GH0 Magnetic Brake is electrically released and spring set braking force is applied when power is removed from the coil. Brake wheels are cast of ductile iron specially formulated to withstand the effects of frequent brake operation. The dc magnetic coil used with the GH0 brakes is encapsulated and enclosed in a weatherproof stainless steel housing. It can be operated from an ac power source by using the optional GH Rectifier Panel. GH0 Magnetic Brakes conform to AISE and NEMA standards for heavyduty shoe brakes. The brake assembly includes a base, a brake coil, two armatures, two shoe levers, plus a brake wheel for mounting on an appropriate rotating shaft. The brake coil is designed for operation with direct current power. When only alternating current power is available, a suitable power rectifier unit must be provided. When the brake coil is energized, the armatures move together to compress a torque spring and move the shoes away from the wheel, thus releasing the brake. De-energizing the coil allows the torque spring to separate the armatures and press the shoes against the wheel. This brake design is therefore fail-safe in the event of power failure. Brake release and set times are.0 seconds or less. GH0 brakes meet all pertinent specifications of NEMA Standard -0 and AISE Standards No. 6 and No.. Outer Shoe Lever Figure. Energized Coil Outer Armature Inner Armature Coil Inner Shoe Lever If brake release and set times are critical, consult Eaton for data and recommendations. Eaton has the most simple, most easily understood design of any brake on the market. There are only parts. This simplicity means maximum reliability in actual operation, as well as ease in installation and maintenance. Cutler-Hammer brakes by Eaton Corporation meet AISE/NEMA mounting dimensions and have the smallest overall dimension, so they can replace any AISE/ NEMA brake of any manufacture and save space in the bargain. They are the heaviest brake available meeting AISE/ NEMA dimensions. This higher strength through weight varies from 0 to 0 percent over some well known brands. Note: The installation and use of Cutler- Hammer products by Eaton Corporation should be in accordance with the provisions of the U.S. National Electrical Code and/or other local codes or industry standards that are pertinent to the particular end use. Installation or use not in accordance with these codes and standards could be hazardous to personnel and/or equipment. Over the Wheel Design Torque Spring Eaton s Cutler-Hammer brakes effectively divide the braking force between the pull rod and lower pivots while transmitting the braking force to the outer shoe lever. Braking action is spread evenly over both shoes, providing maximum stopping power with minimum wear to the brake. What s more, this design eliminates complicated linkages which have additional stress and wear points. It is the ultimate in design simplicity and the key to reliable performance. It reduces the number of required parts only 0 major ones thus keeping maintenance problems and downtime to a minimum. All parts are readily accessible and easily removable. Double locking nuts on the pull rod hold the brake in adjustment, even when subjected to vibration and mechanical pounding. Minimized Wear Bearing wear is minimized at the shoe levers because of the large bearing area provided and the close tolerance fit of the levers into the sockets in the base. An improved angle bracket eliminates frequent adjustment. Longer adjusting screws allow the brake to operate with fewer adjustments per time period. Encapsulated Coil The coil is encapsulated for long service life and consistent reliability. A stainless steel housing provides complete environmental protection. And, because the coil can easily be reversed with the terminals facing either away from or towards the wheel, cable connections are certain to be simple. The single coil design provides greater reliability compared to dual coil designs. CA08000E

3 October 008 Heavy-Duty Brakes Shoe Brakes Magnetically Operated Long-Life Brake Wheels One-Time Shoe Positioning Shoe Adjustment Indicators Brake wheels are made of ductile iron. Specially processed and particularly well suited for indoor or outdoor applications. The physical properties of ductile iron make it resistant to high temperatures associated with frequent braking operations. Scored wheel surfaces resulting from wheel particles lodging in the brake linings are eliminated. Easy Brake Torque Adjustment That is all it takes. Once properly positioned, the brake shoes need no further attention ever. Cap screws and gripping blocks rigidly secure them to the brake shoe levers and prevent the shoes from tilting and riding the wheel when the brake is released. Self locking shoe clamp screws hold the brake in adjustment even when subjected to severe vibrations. Asbestos-Free Shoe Linings Eliminate guesswork in adjusting shoe travel to compensate for lining wear. It is so easy it can be done accurately even in the dark no gauges, no rulers necessary. When the travel of the individually adjustable shoes is just right, sounding pins on the upper sides of the armature are flush with the surface of the bushing you can tell with a touch when adjustment is perfect. Adaptable to ac Applications Adjustment is accomplished by turning the adjustment nut clockwise until a definite stop is encountered. This applies maximum brake torque quickly and easily. To reduce torque, adjustment is counterclockwise. A special construction feature prevents overtightening of the spring, to eliminate overstress and any danger of stud breakage. Eaton s Cutler-Hammer brake shoe linings are manufactured of improved, long-life, low-wear material. Either bonded or riveted brake shoes are available to match your operating conditions and relining capabilities. Use of the Rectifier Panel provides the desirable fast speed and long life characteristics of dc braking on ac service. The panel is connected to the ac motor terminals to provide intermittent brake torque on installations where a continuous duty brake coil rating is required. For reduced voltage starting or drift point settings, the rectifier is connected directly to the ac power source. CA08000E

4 Heavy-Duty Brakes Shoe Brakes Magnetically Operated October 008 Application Description Magnetic brakes are used for both stopping and parking service on industrial machinery. These brakes are widely used on both hoist and travel motions of cranes and other moving machinery. They are also used as parking brakes for industrial process line equipment. Brakes are for use in both indoor and outdoor applications. Brakes can be released electrically by a separate operator s switch, or may be operated in conjunction with control of the related motor drive. Brake System Selection The number of brakes required for a mechanical drive is related to the number of drive motors required for that function. Normally, there is one brake per motor. However, for hoists and other machinery requiring a high degree of safety, two brakes per motor are sometimes specified. Brake Size Selection Selection of the correct brake size is based on the torque requirements of the application. When the brake is used on a motor shaft or extension thereof, the following formula can be used: T = x hp r/min. Where T = Full load motor torque in lb.-ft. hp = Motor rated horsepower r/min. = Rated speed of the motor shaft that brake wheel is mounted on (revolutions per minute) Note: See Table on Page 6 for typical motor frame torques. The rated motor torque arrived at using this formula is adequate for most types of service. However, for hoist and other high inertia applications, refer to factory. All brakes can be mechanically adjusted down to 0% of their maximum torque rating. Brake torque ratings are related to the type of coil chosen and the duty cycle of the brake application. Hoist Brake Selection AISE Standard No. 6 and OSHA Regulations state that the hoist brake is to be selected based on the torque required to hoist rated crane load at the point where the brake is applied. Table. Hoist Brake Selection CMAA OSHA AISE Basis for Selection of Brake Torque Motor Full Load Torque Torque Required to Hoist Rated Load Torque Required to Hoist Rated Load CMAA Specification No. 70 states that the hoist brake is to be selected based on motor full load torque at the point where the brake is applied. All three standards require that a hoist drive handling hot metal be equipped with two brakes. Control braking is dynamic lowering, countertorque or eddy current load brake. Coil Selection Brake Torque Rating Hoist Drive with Single Brake With Control Braking Series coils are normally used with series wound dc motors to reduce the amount of wiring from the control point to the brake, such as between a crane bridge and trolley. The dc motors are intermittent duty, rated one hour or / hour duty. The brake should be selected at the same duty rating as the motor. When the data is available, the coil should be chosen based on the actual full load current and duty cycle of the motor (rather than the rated full load motor current). A coil selection chart for series coils is on Page 0. Brakes with series coils are designed to release at 0% of rated current and set at 0% of rated current. Shunt coils are normally used in applications employing:. Travel motions,. Shunt or compound wound dc motors, or. An ac power supply. If the application requires the brake to be released continuously (energized), brake size should be determined using the continuous duty torque ratings. However, if a coil protective circuit is employed, such as found in the GH Rectifier Panel, selection can be based on the intermittent duty ratings. With Mechanical Load Brake Shunt coils should be selected based on the dc voltage supply to the brake and on the duty cycle of the brake. A resistor wired in series with the shunt brake coil is used to obtain desired brake response time. This resistor is supplied either with the brake (in a package attached to brake pull rod) for user installation, or as a part of the optional Rectifier Panel. When shunt wound coils are used on a dc constant potential power system, a shunt brake relay is required. The relay along with the series resistor can be mounted on the related motor control panel. See Page for obsolete coil cross references. Wheel Selection Hoist Drive with Two Brakes Handling Hot Metal % 00% 00% 00% % 00% 00% 00% 0% 0% % 00% Not Handling Hot Metal Wheels should be selected from the tables on Pages 9 and 0. Wheels are ductile iron machined for gear box or motor shaft mounting. GH0 Magnetic Shoe Brake CA08000E

5 October 008 Heavy-Duty Brakes Shoe Brakes Magnetically Operated Enclosure Selection When brakes are exposed to adverse environmental conditions, optional brake covers or enclosures should be considered. The weather-resistant enclosure protects the wheel and brake shoes from rain, snow or sleet at any normal wind conditions. The NEMA enclosure protects the complete brake and wheel assembly from any type of moisture or dust impingement. To maintain watertightness, a shaft seal must be added by the factory or customer. Use of this enclosure affects the wheel centerline height dimension. Approximate enclosure dimensions are shown on Page 7. Features Seven AISE sizes available: 8, 0,, 6, 9, and 0 inch. Torque ranges from 0 to 9000 lb.-ft. Ductile iron bases with steel armatures on sizes 8 thru inch. Steel base with laminated steel armatures on 0 inch size. Partial wheel covers, weather resistant and NEMA - enclosures. DC series or shunt coils available, or coils for use with rectifier ac power. Simplest construction of any brake in the industry. Mechanical options and brake rectifier packages available. Optional Features Riveted shoe linings (standard on " brakes). Special brake wheel dimensions. Weather-resistant enclosure. NEMA watertight and dust-tight enclosure. Manual release lever type, self return. Manual release Screw type, maintained. Low torque rating for 8" brake. Brake release indication circuit. Visual torque measurement gauge. Optional Manual Release Lever Construction Features Major structural parts, including the brake base, shoe levers, shoes and the brake wheel, are machined from ductile iron casings. The ductile iron used in the brake wheel is specially formulated to withstand the high temperatures normally resulting from frequent brake operation. Wheels can be machined to cover a variety of motor shaft or line shaft requirements. Note: The 0" brake size only incorporates laminated steel armature members and a fabricated steel base. Brake linings are bonded to brake shoe lining inserts of sheet steel. The inner and outer armatures are machined from cast steel to obtain optimum magnetic properties. The brake coil is strap or wire wound and epoxy filled for long service life and top reliability. A weatherproof stainless steel housing provides complete environmental protection and eliminates the possibility of magnetic dust or kish build-up. Standard coil leads extend about " Outer Shoe Adjustment Outer Shoe Lever Figure. GH0 Brake Cutaway View Pull Rod Wheel Shoe and Lining Inner Shoe Adjustment from housing face and are supplied with suitable lugs. Coil terminals can be oriented to either face away from or toward the brake wheel. Coils are wound with Class B insulation. The over-the-wheel design of GH0 brakes effectively divides the braking force between the pull rod and lower pivots while transmitting the braking force to the outer shoe lever. As a result, the braking action is spread evenly over both shoes, providing maximum stopping power with minimum wear to the brake. Brake shoes and linings are available in either bonded or riveted construction. Linings are of a non-asbestos material having excellent wear and anti-fade characteristics. Brakes can be easily adjusted for lining wear. The mechanical design of the brake eliminates all but one pivot pin the pin connecting the pull rod to the outer armature. Bearing surfaces between the shoe levers and base, as well as armatures and base, are generally sized to minimize wear and help prevent freezing of the pivots. All mounting and shaft height dimensions are in accordance with Association of Iron and Steel Engineers Standard No.. See Page for these dimensions. Parking torque is easily adjusted over a : range using a standard wrench. Inner Shoe Lever Torque Spring Coil Outer Armature Inner Armature Sounding Pins Torque Adjustment Brake Base CA08000E

8 8 Heavy-Duty Brakes Shoe Brakes Magnetically Operated October 008 GH0 Brake Wheel for Straight Shaft with Keyway Accessories Brake Wheels These brake wheels are manufactured in 7 AISE sizes from ductile iron conforming to ASTM Steel wheels are also available. Stocked wheels are set up for mounting on mill and industrial motor shafts. Wheels with a pilot bore are also available for the OEM market. Wheel Selection Brake wheel selection is dependent on the dimensions of the shaft on which it will be mounted and on the location of the motor end bell and mounting feet with relation to the brake. Most commonly, these brake wheels are mounted on a motor shaft extension opposite the drive end shaft. Sometimes the brake will be located on the high speed shaft between the motor and gear box. Occasionally there will be a high speed shaft extension on the opposite side of the gear box where the brake can be located. For dc mill motors, where the brake is to be located on the motor shaft extension opposite the drive end, standard wheel dimensions have been established (AISE Standard No. ). On Pages 9 0, Table lists brake wheels where a Standard wheel has been set up for various motor frames. If wheel requirements do not match motor frame listing availability, then two alternatives are open:. Choose the Universal wheel, which is a partially finished wheel. This wheel has the maximum amount of hub length and a pilot bore. The customer must machine the hub to the required length, and the required bore and keyway dimensions.. Order a Special brake wheel with all machining completed by Eaton s Cutler-Hammer. C, D, Bore, Taper (if required), and keyway dimensions must be specified. See brake wheel dimension drawing, Figure on Page for maximum and minimum dimensions. Note that wheel dimensions will always be Special when a NEMA enclosure is required.

43 October 008 Contactors and Relays DC Contactors Type C80 Cat. No. C80FJN00 Size NC Contactor Product Description These dc mill type contactors are designed for heavy industry service and are suitable for use on moving machinery. The contactors listed in this section are for surface mounting on steel panels and front-of-panel wiring. The power stud assembly is mounted on the side of the contactor, rather than as part of a separate mounting kit. These contactors utilize dc coils. If control power is 0 Vac, the rectifier module listed on Page should be used in conjunction with a 00 V coil contactor. Auxiliary contacts and mechanical interlocks for use with these contactors are listed on the following pages. The contactors feature forged steel armature levers and magnet frames for superior physical strength. Selflubricating bearings eliminate the need for lubricating the contactor. Hotmolded arc chute assemblies contain no asbestos and have better arc extinction characteristics for longer contact life. The short stroke armature results in a mechanical life of more than 0 million operations. The arc chutes and magnetic blowout structures are designed to quickly absorb and dissipate the heat caused by arcing. In addition to increasing contact life, the molded arc chute Cat. No. C80DGN00 Size Pole Contactor offers advantages of improved mechanical life and cooling characteristics plus superior arc-tracking resistance. The arc chutes are hinged to provide front accessibility, easy inspection or replacement of contacts without removing any other contactor parts. Construction of the pivot pin assembly provides positive pin locking so that the bearing pin remains stationary with respect to the operating movement of the forged armature. A leaf spring attached to the unit base and the arc chute holds the chute in the down or functioning position. The addition of this assembly resists the violent vibrations encountered on open hearth charging machines and on a wide variety of crane applications. Pre-drilled mounting holes are provided on the unit base to accommodate interlock mounting brackets. An interlock is merely attached to a bracket and the assembly is then bolted in the desired operating position on the contactor. DC Drive Service Contactors Eaton s Cutler-Hammer industrial type contactors modified for dc drive service are provided with silver faced contact tips, to provide optimum contact structure and minimum maintenance under continuous duty service. These contactors are designed for steel panel surface mounting. Power studs are a part of the contact or assembly. Standards and Certifications CMAA NEMA ICS-,,. NEMA ICS-.. NEMA ICS NEMA ICS-..0.

53 October 008 Contactors and Relays DC Contactors Type C8 Ltl Inductive Time Limit Cat. No. 6006H0 Size dc Ltl Contactor Product Description DC Inductive Time Limit (Ltl) Contactors are mill type contactors used for acceleration and plugging functions. The contactor uses two coils; one a normal closing coil, and the other a holdout coil. When the closing coil is energized, the contactor will not pick up until the magnetism of the holdout coil has decayed sufficiently to permit the contactor to close. By connection of the holdout coil (H.O.) to various points in control circuits, the Ltl contactor can be used to control acceleration or plugging in hoist and travel panels. The construction of the arc chute, blowout and power contacts of these contactors is the same as for C80 DC contactors. Contact tips, closing coils, arc chute assemblies, and interlocks are interchangeable between the two types of contactors. Refer to Page for a description of these features. Course adjustment of the timing is accomplished by removing shims to vary the air gap of the holdout coil circuit. Fine adjustment is made with a knurled nut at the base of the holdout coil magnet core. Standards and Certifications NEMA ICS-,,. NEMA ICS-.. NEMA ICS NEMA ICS-..0.

60 60 Contactors and Relays DC Contactors Types KD & KS October 008 Blowout Coil Rear Arc Runner Direction of Arc Arc Contacts Front Arc Runner Type KS NC Pole 0 Ampere Product Description Bulletin 700 Type KD (Normally Pole) and Type KS (Normally Closed Pole) contactors are designed for frontmounting directly on steel panels and require no special hardware or insulators. Electrical clearances are integrally designed into the devices by the use of hot-molded reinforced polyester insulators. These dc mill type contactors are designed for heavy industry service and are suitable for use on moving machinery. The contactors listed in this section are for surface mounting on steel panels and front-of-panel wiring. These contactors utilize dc coils. If control power is 0 Vac, the rectifier module listed on Page should be used in conjunction with a 9V coil contactor. Auxiliary contacts and mechanical interlocks for use with these contactors are listed Pages 6 and 6. The contactors feature forged steel armature levers and magnet frames for superior physical strength. Selflubricating bearings eliminate the need for lubricating the contactor. New hot-molded arc chute assemblies contain no asbestos and have better arc extinction characteristics for longer contact life. The short stroke armature results in a mechanical life of more than 0 million operations. The arc chutes and magnetic blowout structures are designed to quickly absorb and dissipate the heat caused by arcing. In addition to increasing contact life, the molded arc chute offers advantages of improved mechanical life and cooling characteristics plus superior arc-tracking resistance. Long Life Type KD NO Pole 00 Ampere Extended operating life for Type K contactors results from roll action of contacts, and the transfer of arc to front and rear arc runners. Arc shield and blowout structure guides and dissipates the hot arc and provides high interrupting capacity. Type K 0 ampere contactors are designed with a unitized head assembly front mounted with only two screws. These assemblies are available with blowout coils rated, 7.,, and 0 amperes or without blowout, and are easily changed in the field. Figure 6. Blowout Coil Effect on Arc Coils, head assemblies, contacts, arc shields and flexible connectors are identical for all 0 ampere contactors providing lower inventory of parts. They are also the same height as dc members of the PM Relay family ideal for wireway panel mounting. Type KS Normally Closed Pole Contactors Type KS contactors have similar design and construction features to Type KD normally open pole contactors with many parts duplicated. The Type KS contactor operates with a snappy positive action requiring no retarding coil, series resistor or tapped coil. Knife-Edge Pivot Design Type K contactors feature an exclusive shrouded knife-edge pivot which excludes dirt. On 00 ampere and larger sizes, a three-edge design provides reliable adjustment and rattleproof operation. Arm weight is supported by a vertical knife in the center, while horizontal knives at both sides ensure alignment. Convenient Accessories Mechanical interlocks and control circuit contacts are furnished in convenient kit form along with necessary hardware. No special drilling is required on panels or contactors. A line of front wired, mill-type accessory devices including control, timing and overload relays are available and are compatible with Type K contactors. CA08000E

Product Description The Low Voltage Monitoring Relay (LVMR) is designed specifically to address power loss during hoist lowering (regeneration) operation. The LVMR continuously monitors bus voltage and de-energizes the UV relay if the bus voltage falls below a value that will safely operate contactors and relays. The LVMR distinguishes the difference between main power and regeneration power produced by a motor. It constantly monitors the dc bus voltage and sets the series brake automatically when it detects a power loss condition. When the voltage drops below the point where relays or contactors can reliably pick up and seal (as defined by the current NEMA standards), the hoist control panel will shut down and set the brake. Installation Installation requires mounting one device in your existing hoist panel and adding two wires. Remove the wire lead from the existing UV coil and the last protective interlock. Mount the LVMR as close as possible to the existing UV relay and reconnect the removed wire to the LVMR interlock at terminal. Add a wire from the other side of the LVMR interlock, terminal 6, to the original UV coil terminal. Using the supplied terminal lug, connect a wire from terminal on the electronic module to L on the other side of the UV coil. Wiring Diagram L(+) Figure.

74 7 Contactors and Relays DC Relays Field Control October 008 Technical Data and Specifications DC Field Loss Relay Product Description This family of motor field control relays consists of a relay with NO pole (#90) and a relay with NC pole (#90). These relays are used on a large number of applications requiring either an NO or NC control contact. The opening and closing of the contact is responsive to changes in current through the coil. The relays are equipped with one or two coils, depending on the application. When the relays leave the factory, they are adjusted for average load conditions. This adjustment is made up of two parts:. The adjustment of the differential, which is the difference between the opening and closing setting, and. The adjustment of the range or operating values.

77 October 008 Contactors and Relays DC Relays Types KPR & KFL Special Application 77 Technical Data and Specifications Voltage: Maximum 600 Vdc. Operation: Magnetic. Mounting: Steel panel or insulated panel Dimensions Contact Ratings: amperes at 0 V 0 amperes at 0 V Duty: Continuous. DC Plugging Relay Product Description Type KPR Plugging The Type KPR Relay features a diode assembly mounted on the relay base and wired in series with the relay operating coil. The relay detects when a dc motor is being plugged. (Plugging is the sudden reversal of the polarity applied to a relay motor causing it to rapidly stop and reverse rotational direction.) The coil circuit of the plugging relay is connected to parallel with the motor armature and monitors armature voltage. During normal dc motor operation, the diode is non-conducting and the relay is de-energized. During motor plugging, polarity reverses, causing the diode to conduct and operate the relay. The contacts of the relay cause motor circuit contactors and resistors to properly plug the motor. Type KFL Field Loss The Type KFL relays are no longer manufactured. The suggested replacement is the Type 90 single-pole normally open relay. Refer to Page 7 for application and ordering information.
