2 J o o DC CRANE CONTROL JANUARY, 1981 APPLCATON DATA DC MOTOR DATA ASE FRAME 600 AND 800 MOTORS The following typical motor data is based on the information published in the ASE Standard No. 1, DC Mill Motor Standards. 4 This information should be used to select the proper crane controllers and crane accessories: 1. NEMA standards require that crane controllers be selected on the intermittent motor rating (30 minute or 1 hour rating) at which the motor is applied. 2. ASE standards require that hoist controllers be selected based on the 30 minute rating of the hoist motors. 3. ASE standards require that bridge and trolley controllers be selected based on the 1 hour rating of bridge and trolley motors.

3 JANUARY, 1981 DC CRANE CONTROL APPLCATON DATA CMAA CRANE SERVCE CLASSFCATONS Service classifications have been established to enable the user to specify the crane operating duty and motor control requirements. The Crane Manufacturers Association of America (CMAA) has seven classes which describe crane operating duty. CLASS A This Class is further divided into two subclasses due to the nature of the loads to be handled. CLASS A1 STANDBY SERVCE This service class covers cranes used in installations such as; power houses, public utilities, turbine rooms, nuclear reactor buildings, motor rooms, nuclear fuel handling and transformer stations, where precise handling of valuable machinery at slow speeds with long idle periods between lifts is required. Capacity loads may be handled for initial installation of machinery and for infrequent maintenance. CLASS A2 NFREQUENT USE These cranes will be used in installations such as: small maintenance shops, pump rooms, testing laboratories, and similar operations where the loads are relatively light, the speeds are slow, and a low degree of control accuracy is required. The loads may vary anywhere from no load to full capacity with a frequency of a few lifts per day or month. CLASS B LGHT SERVCE This service covers cranes such as used in repair shops, light assembly operations, service buildings, light warehousing etc., where service requirements are light and the speed is slow. Loads may vary from no load to full rated load with an average of 50% of capacity with 2 to 5 lifts per hour, averaging 15 feet, not over 50% of the lifts at rated capacity. NEMA SERVCE CLASSFCATONS CLASS C MODERATE SERVCE This service covers cranes such as used in machine shops, papermill machine rooms etc., where the service requirements are medium. n this type of service, the crane will handle loads which average 50% of the rated capacity with 5 to 10 lifts per hour, averaging 15 feet, not over 50% of the lift at rated capacity. CLASS D HEAVY DUTY This service covers cranes, usually cab operated, such as are used in heavy machine shops, foundries, fabricating plants, steel warehouses, lumber mills etc., and standard duty bucket and magnet operation where heavy duty production is required but with no specific cycle of operation. Loads approaching 50% of the rated capacity will be handled constantly during the working period. High speeds are desirable for this tvpe of service with 10 to 20 lifts per hour, averaging 15 feet, not over 65% of the lifts at rated capacity. CLASS E SEVERE DUTY CYCLE SERVCE This type of service requires a heavy duty crane capable of handling the rated load continuously at high speed, in repetition throughout a stated period per day, in a predetermined cycle of operation. Applications include magnet, bucket, magnetbucket combinations of cranes for scrap yards, cement mills, lumber mills, fertilizer plants etc., with 20 or more lifts per hour a11 at rated capacity. The complete cycle of operation should be specified. CLASS F STEEL MLL ASE SPECFCATON Cranes in this class are covered by the current issue of The Association of ron and Steel Engineers Standard, No. 6 for Electric Overhead Traveling Cranes for Steel Mill Service. Two service classifications have been established to enable the user to specify motor control requirements. The motor control service classifications refer to the CMAA Crane classifications above. CLASS These motor controls are intended for use with all CMAA crane service classes except A2 and B. CLASS These motor controls are intended for use with CMAA crane service classes A2 (nfrequent use) and _!i (light industrial service). :J SQURRED COMPRNY 5 www. ElectricalPartManuals. com com

9 JANUARY, 1981 DC CRANE CONTROL CONTROLLER MODFCATONS Standard controllers come equipped with the components listed. Special features to be added to standard controllers are identified by Form Y35 and a modification number. Most of these modifications are selfexplanatory. however, require some additional explanation. APPLCATON DATA Others, MODFCATON NO. 4 lists a second plugging step. An additional plugging relay (2PR) and an additional plugging contactor ( 2P) are supplied. A second plugging step is recommended for heavy cranes, such as ladle crane bridge drives or high speed cranes such as ore bridge trolleys or high speed bridge drives. Two steps of plugging provide faster slowdown without spinning the wheels. MODFCATON NO. 7 lists series brake transfer knife switches for use on duplex controllers. For single motor operation, these knife switches connect the series brakes in series with one motor to permit operating the drive without having to manually release one brake. MODFCATON NO. 9, service dynamic braking, is used for decelerating travel drives under normal operation. Service dynamic braking is occasionally used in place of plugging on a travel drive. The common arrangement is to use an initiating switch in conjunction with the electric adjustable torque or hydraulic brake pedal such that initial depression of the brake pedal provides service dynamic braking and further depression actuates the hydraulic brake. Service dvnamic braking assists the hydraulic brake. Serv1ce Dynamic Braking for single ser1es motor. MODFCATON NO. 10. o OL "f. 1+ covers emergency dynamic braking. Emergency dynamic braking is used to decelerate crane travel drives, such as high speed bridge drives and manned trolleys and is automatically applied upon power failure or when an overload relay trips. Emergency dynamic braking provides a simple, reliable means for braking to a stop, bridge drives of cranes or manned trolleys of ore and coal bridges, etc. Emergency dynamic braking is applied in about 1 5 the time required to set a shunt brake. The motors are converted to selfexcited generators to provide retardation. Braking is not dependent on an outside source of power. The circuits for single step emergency dynamic braking (Modification No. 10) are shown for the various motor connections. The motor i connected as a selfexcited generator by using a silicon rectifier bridge around the motor series field. Braking is equally effective in each direction. Emergency Dynamtc Brakmg for single motor. Emergency Dynamic Braking For A Single Motor M o Emergency Dynamic Braking For Two Motors Connected n Series The same circuit as for a single motor is used. The armatures and fields of the two motors are permanently connected in series and are treated as a single motor. Emergency Dynamic Braking For Two Motors Connected n ParaUel The circuit shows the simple arrangement whereby the fields and the armatures of the two series motors are crossconnected to insure selfexcitation for positive emergency dynamic braking from either direction of travel. Two sets of doublepole dynamic braking contactors arc used. DYNAMC BRAKNG RESSTOR Emergency Dynamtc Brak1ng for 2 motors 1n parallel. :J SQURRE D CCMPRNY 11

10 CONTROLLER MODFCATONS (CONTD) DC CRANE CONTROL Emergency Dynamic Braking For Four Motor Drives For four motors connected in parallel, two sets of crossconnected motors are connected in parallel to provide dynamic braking for all four motors. For this motor connection, the controller modification is priced by doubling the price given for two motors in parallel. When four motors are connected in series parallel, that is, when two sets of motors with their armatures and fields connected in series are connected in parallel, emergency dynamic braking should be priced based on the controller modification for two motors connected in parallel. MODFCATON NO. covers graduated emergency dynamic braking with automatic deceleration. The automatic deceleration provides a faster stop than single step deceleration from high speed without wheel slippage. Graduated Emergency Dynamic Braking With Automatic Deceleration For A Single Motor An additional voltage relay (2VR) and a spring closed contactor (3DB) with its main contacts shorting out a portion of the dynamic braking resistor are added to the circuit for single step emergency dynamic braking. The two voltage relays ( VR and 2VR) are used to insure proper operation o f the 3DB contactor. The generated armature voltage keeps the 3DB contactor energized until the motor speed is decreased sufficiently to provide a smooth deceleration. When the 3DB contactor closes, the value of the dynamic braking resistance is decreased, and increased braking torque is provided to stop the drive. +.. Graduated Emergency Dynamic Braking with Automatic deceleration for a single motor. APPLCATON DATA JANUARY, 1981 Graduated Emergency Dynamic Braking With Automatic Deceleration For MultiMotor Drives For two motors connected in series, the fields of each motor are connected in series inside the rectifier bridge and are treated as a single motor. For two motors connected in parallel, the basic circuit for two motors in parallel with emergency dynamic braking (Modification No. 17) is used except that two voltage relays ( 1 VR and 2VR) and two spring closed contactors (3DB and 4DB) are added. The voltage relays and the two spring closed contactors operate from the generated armature voltage of one motor and control the braking of both motors. The additional spring closed contactor ( 4DB) is connected with its coil in parallel with the 3DB contactor coil and its normally closed contact shorts out part of the dynamic braking resistor in the second motor power circuit. For quadruplex connections where four motors are connected in parallel, it is necessary to double the controller modification price shown for two motors in parallel. For four motors used in a seriesparallel connection, graduated emergency dynamic braking should be priced based on the controller modification price for two motors connected in parallel. MODFCATON NO. 12, a shunt brake relay is primarily intended for use on bridge and trolley drives using shunt brakes. The brake relay is commonly arranged for operation from a separate push button station to allow manual control of the brake. MODFCATON NO. 13 covers a voltage sensitive relay. An application for this addition would be the second voltage relay on a hoist drive. 2 VR protects against overspeeding and automatically returns the drive from the last point lower to the next to last point in case of overspeeding. MODFCATON NO. 19 lists low headroom panel construction. this type construction. Class 6121 controllers are not available with Class 6131 controllers with 5th speed point and negative line contactor additions should be used. MODFCATON NO. 24 provides time delay acceleration proportional to motor current. 12 SQUARED COMPANY D

Price master switch from Class 6121 master switch selection tables. Special features to be added to standard controllers are identified by Form Y35 and a modification number. Modifications SA and SB are armature shunt contactors for use on Bridge and Trolley controllers only. APPLCATON DATA Each modification consists of a single pole normally open contactor of equal NEMA size to the contactors in the b_asic controller. The operation of each is as follows: SA: Contactor arranged to provide extra slow first speed point. This modification is to be used with a NEMA Class 152 or 162 PAS resistor filling. SB: Contactor arranged to provide slowdown of bridge drives during floor operation of cab/floor operated cranes. This modification is to be used with NEMA Class!52 or 162P accelerating resistors plus a continuous duty bridge slowdown resistor. Modifications 12A, 12B, and 12C cover various shunt brake relay applications. These modifications are for Bridge and Trolley controllers only and in each case a double pole 25 ampere brake relay is supplied. The three modifications differ from each other in the way the relay is wired and controlled. Each is as follows: 12A: Relay interlocked with reversing contactors through N.O. electrical interlocks. With this arrangement the shunt brake will set whenever the controllers master switch is moved to the off point. 12B: Relay controlled from external push button, foot switch, etc. This arrangement allows the shunt brake to be manually applied by the crane operator whenever necessary. 12C: Relay connected in parallel with undervoltage relay. The arrangement allows the shunt brake to set only when the main disconnect for the crane is opened or upon power failure. NEMA SEitVCE CLASSFCATON Standard controllers meet the requirements of NEMA service A2 and B). classification (CMAA service classifications To meet the requirements of NEMA service classification (CMAA service classification A> C, D, E and F), the controller must be priced with the additional acceleration point, Form Y353 and the negative line contactor, Form Y D9A DSCOUNT SQUARE DCDMPRNY D
