Read this chapter carefully and thoroughly. In particular, observe the safety instructions in Chapter 2 “Your safety”.

History In the early 1970's, S&S Corporation lead the way in mining innovation with the introduction of solid state speed controls for battery-powered underground mining equipment. Solid state controls increased the range and reliability of the battery powered vehicles along with providing smooth, stepless acceleration. Even with solid state speed control, direction change was achieved with the use of electromechanical contactors. These contactors provided an endless source of maintenance problems and consumed excessive amounts of valuable controller-box space. Also, most solid state controllers of the past utilized an electromechanical "bypass" contactor to connect the motor directly to the batteries which caused more contactor problems.

In the 1980’s Bucyrus America, Inc., in conjunction with Sevcon, developed a contactorless motor controller (X90) to be used exclusively on Bucyrus equipment. The X90 system used a dual-field motor in combination with SCRs (Silicone Controlled Rectifier) to achieve solid state direction change.

Now Bucyrus America, Inc., in conjunction with Sevcon, has developed the BUC2000 motor controller. The BUC2000 system uses IGBTs (Insulated Gate Bipolar Transistors) to achieve motor control and direction change. Unlike an SCR, an IGBT is turned ON and OFF via a gating electronic signal. This eliminated commutating capacitor banks and coils. The microprocessor based BUC2000 Logic Card provides complete motor control and drives both a Diagnostic Dashboard Display along with a hand held Calibrator/Diagnostic Unit.

The IGBT switch operates so fast that it can connect and disconnect the motor in less than 1/1700 second. This is such a short time period that the dual-field motor does not have time to move. Each time the IGBT switch closes and reopens, the full battery voltage is applied to the motor terminals for about 1/1700 second. This is commonly referred to as a "pulse." (Fig. 1) The IGBT speed control works by feeding to the motor a rapid series of pulses. The number of pulses per second determines the average voltage at the motor terminals. (Fig. 2)

_________________________________________________________________ 3.4 BUC2000— Dual and Single Motor Solid State Controllers

___________________________________________________Operation Since the windings of the motor are inductive, the current in the motor cannot change quickly. When the IGBT switch is closed, the current builds up slowly and when the switch opens, the inductance wants to keep the current flowing. For this reason, the "flywheel" diode is provided. Fig. 3 and 4 illustrate the current paths with the switch closed in both forward (Fig. 3) and reverse (Fig. 4) modes.

Fig. 3: Flywheel diode motor current (forward mode)

Fig. 4: Flywheel diode motor current (reverse mode)

_____________________________________________________________ _ A6474X226 VESV/04 3.5

Operation____________________________________________________ As seen in Fig. 5, the direction of the current through the motor does not change. More important, when the switch opens, although the battery current stops, the motor current continues to flow via the "flywheel" diode. The motor current is therefore made up of two components:  The battery current when the IGBT switch is closed.  The "flywheel" current when the IGBT switch is open.

The amount of the motor current supplied from the battery varies with the pulse frequency. Fig. 6 illustrates a typical situation at low speed. It can be seen from the illustration that the "flywheel" current, because it is flowing for a longer period, forms a larger part of the motor current than does the battery current. However, at high speeds (Fig. 7), the motor current is made up of almost all battery current.

Fig. 5: Flywheel diode motor current (direction does not change)

___________________________________________________Operation

© BUCYRUS AMERICA, INC.

Fig. 6: Flywheel current (low speed)

To summarize, the motor current is made up of a combination of battery current and "flywheel" current so that under all conditions the average motor current is always greater than the average battery current.

At low speeds the motor current can be several times greater than the battery current.

At high speeds, when the IGBT switch is open only for short periods before closing, the motor current is made up almost entirely of battery current.

Operation____________________________________________________ General specifications The BUC2000 Motor Controller is designed to operate at 128 volts DC, 1200 Amps maximum current limit per motor and controls one or two dual-field electric motors.

■

The maximum current default settings are: 800A, 1100A and 1200A.

■ Traction functions operate at a speed that is directly proportional to the accelerator (potentiometer) demand. (See Fig. 8) ■

Traction motor current will be continuously monitored in the motor.

Current limit is preset and is adjustable via the optional hand held diagnostics/calibrator unit and is password protected.

■

4 motor connections for each motor (S1, S2, A1 and A2)

(For power circuit layout see machine wiring diagram and schematic)

Motor current imbalance feature (dual motor only) There is a selectable motor current imbalance time-out feature that allows for a selectable time delay before the controller stops drive if current in one motor is less than 150A and current in the other motor is above 350A. This feature is enabled when the adjustable personality for the timer is set above 0.

Wire off detect In the event of the accelerator input becoming detached, a 6-flash fault diagnostic will occur.

IMPORTANT! An accelerator short will be detected when neutral is selected and it shall cause a 6-flash fault diagnostic.

Fail-safe operation ■

In the event of a shorted IGBT, the circuit breaker will be opened, disconnecting power from the traction motors.

■

Operation of the circuit breaker will always be sensed and, if faulty, drive will be inhibited.

■

Whenever the vehicle is power-cycled, power-up diagnostics will be executed to test the tram drive circuitry. If faulty, drive will be inhibited.

_____________________________________________________________ _ A6474X226 VESV/04 3.9

Operation____________________________________________________ Traction creep speed When traction mode is activated, a fixed creep shall be applied to the traction motors at zero demand.

Displacement of the accelerator input shall result in a linear increase in percentage on from the creep to 100% ON over the full range of accelerator input.

Acceleration delay The traction motor speed control shall incorporate an adjustable acceleration delay facility by applying acceleration delay to changes in the applied percentage on of the switching element.

The duration of the acceleration delay shall be variable between 0.5 seconds and 5.0 seconds and is an adjustable personality accessible via the calibrator.

The traction motor speed control shall incorporate an adjustable deceleration delay facility by applying a deceleration delay to changes in the applied percentage on of the switching element.

The duration of the deceleration delay shall be variable between 0.1 seconds and 5.0 seconds and is an adjustable personality accessible via the calibrator. In effect, this delay reduces motor plugging that results from a change in direction.

Thermal cutback The temperature of the BUC2000 Motor Controller will be continuously monitored and, if it rises above 95°C the motor current will be limited to a maximum of 300 amps.

Deceleration delay

___________________________________________________Operation Data-logging features The BUC2000 Motor Controller features a data logging capability that stores critical data into non-volatile data RAM. The stored data is displayed in the traction status display of the optional hand held diagnostics/calibrator unit.

A list of the data logged parameters are: ■

The current calibration factors for both channels.

■

The peak motor current sensed in each channel.

© BUCYRUS AMERICA, INC.

Note: the shortest duration is 3.0 Mseconds.

■

The capability exists for both channels to record the time duration of motor current sustained at or above a selected recording level.

Once the motor current falls below the selected recording level, the timers are latched and stored into non-volatile memory only if the latest measured time duration is longer than the stored duration.

Thus the stored time duration is always a representation of the longest sustained motor current at or above the selected level. If motor current once again reaches the recording level, the timers are again activated and time measurement once again commences. The maximum duration is over 14 hours. If the recording level personality is changed, the timers and the stored duration time are cleared.

■

The peak plugging current sensed in each channel.

Note: the shortest duration is 3.0 Mseconds.

■

The capability exists for both channels to record the time duration of plugging current sustained at or above a selected recording level (operation as in motor current recording as noted above).

■

____________________________________________ Troubleshooting Troubleshooting This section provides troubleshooting information. This guide assumes you have a working knowledge of IGBT controller servicing and that you have the following equipment.

■ volt/ohm meter or digital meter with diode check function ■ appropriate leads for meter ■ insulated basic hand tools WARNING! Follow all Mine, State, and Federal lockout/tagout regulations.

© BUCYRUS AMERICA, INC.

WARNING! When working inside the controller, use insulated gloves and tools where possible.

WARNING! All connections must be tight and care must be taken to prevent bolts, nuts, washers and other small metal fasteners from being dropped or lost inside the controller.

WARNING! Before starting any power-related performance tests, the machine must be securely blocked clear of the ground with all four (4) wheels free to turn.

NOTICE! Refer to the parts manual for your particular machine wiring diagrams and schematics.

NOTICE! The logic unit contains no user-serviceable parts. Opening this sealed device will void the warranty.

WARNING! Never power up logic without the 32 pin connector connected to the logic. Powering up the logic without the 32 pin connector will result in damage.

______________________________________________________________ A6474X226 VESV/04 3.37

Troubleshooting ______________________________________________ IGBT and diode measurements IMPORTANT! An analog meter or a digital multi-meter with a diode check function is required to obtain reliable readings during the following procedures.

Before taking readings, the following system conditions must be met: Master switch or control handle in the “OFF” position. Panel disconnected from and isolated from the battery (via main circuit breaker) and battery plugs being disconnected. Motor leads disconnected from panel.

After power is removed, wait for one (1) minute before making measurements to allow voltage to bleed down.

WARNING! Never power up logic without the 32 pin connector connected to the logic. Powering up the logic without the 32 pin connector will result in damage.

IGBT measurements Reference Fig. 28 for IGBT measurement.

If reading is 0, IGBT is shorted. There are two IGBTs wired in parallel; therefore, if one IGBT indicates short, it may be one or both.

Troubleshooting ______________________________________________ Driver measurements The measurement of the driver on the Bucyrus America, Inc. BUC2000 Motor Controller cannot be done with a volt-ohm meter.

In order to determine whether the driver is faulty, a process of elimination is required. The LED indicates if there is “look ahead” voltage on the IGBTs and, as such, does not fully indicate whether the driver is working properly or not.

The steps to follow to determine if the driver is faulty are as follows:  Determine if any of the IGBTs or diodes are faulty by performing the previously illustrated tests.

 The reading should be less than the battery voltage, but higher than “B-” (in the range of approximately 70 volts). This voltage may vary panel to panel as there is leakage voltage through the IGBTs and diodes.  If the voltage is at the same potential as “B+”, then most likely a diode is shorted.  If the voltage is at “B-”, then most likely an IGBT is shorted.

The calibrator should indicate which channel is faulty.  If the calibrator does not indicate which channel is faulty, the faulty component can be determined in the following manner:  Remove power from the panel, remove the motor connection leads from the panel and follow the measurements as indicated in the previous sections, or determine which channel is faulty.  If all the IGBTs and diodes measure okay, the problem may be with the driver or the logic board.

_________________________________________________________________ 3.44 BUC2000— Dual and Single Motor Solid State Controllers

© BUCYRUS AMERICA, INC.

 With power applied, the master switch or control handle to the “PARK” or “PARK BRAKE APPLIED” position, and all motor leads connected, measure the voltage with a volt-ohm meter from “B-” to the motor connection leads, each in turn (“S1” to “B-”, “S4” to “B-”, and so on).

Chapter 6: Technical data

© BUCYRUS AMERICA, INC.

IMPORTANT! Due to the application of fasteners being subject to great stresses and heavy or extreme vibration, it is imperative that all bolts be applied with an adequate amount of torque. For this reason this list of recommended torque settings for different types and sizes of fasteners used has been compiled. The tightening torques stated in the spare parts lists have to be observed, as well, for installation and maintenance.

NOTICE! Use only lubrication fluids and greases approved by Bucyrus America, Inc. ! These fluids and greases have been tested at Bucyrus America, Inc. and guarantee reliable operation of the mechanical and hydraulic functions of the machine.

IMPORTANT! The lubrication fluids and greases listed in the same table can be mixed. Other products may only be used if the supplier can guarantee that they are equivalent. Differently composed fluids and greases must not be mixed as this may change the consistency, i.e. the mixture can become thinner so that the lubrication effect is not sufficient. It may also be dangerous to use lubricating greases and fluids having the same specification base but different origins. In case of doubt, the manufacturer of the lubrication to be used should be contacted as to the compatibility of the lubrication in question.

IMPORTANT! Bucyrus America, Inc. expressly point out that the approval of the listed products relates only to the pure technical use in our mechanical and hydraulic systems. The responsibility for the constituents used in the hydraulic concentrates lies solely with the respective manufacturer.

NOTICE! When performing maintenance on the machine, all used oil and lubricants should be disposed of per your local EPA standards.

Careful attention to the points in this chapter will help you to simplify your day-to-day work.

Storage corrosion protection

Components coated with temporary corrosion inhibitor are protected for approximately six months.

© BUCYRUS AMERICA, INC.

Before delivery, the hydraulically operated equipment is operated and all axles, gear boxes, hydraulic oil tank, etc. are filled to their maximum fill point.

Storage of the machine and spare parts no direct exposure to sunlight

dirt and moisture

Store the equipment indoors or cover with a tarpaulin to protect against direct exposure to sunlight. Store the electrical equipment, electronic components, spare parts of rubber or plastic – such as seals and hoses – and hydraulic fluids only in closed rooms at temperatures of 60° F (15° C) to 77° F (25°C).

Protect the equipment and all spare parts stored outdoors against moisture and dirt, e.g. using tarpaulins.

The mounting surfaces of hydraulic components must be protected against corrosion and sealed with blind plates. Protect the hydraulic plug connectors and the connectors of the electrical cables with the caps and plugs supplied.

short-term storage

During short-term storage (approximately 4 weeks) of equipment outdoors, but at temperatures above freezing, electrical components need not be removed. Such components must be particularly protected against excessive temperatures, dirt and moisture.

long-term storage

If the equipment is to be stored more than six months, the hydraulic components must be completely filled with a corrosion inhibiting/frostproofing fluid.

Fill the hollow areas of hydraulic components (e.g. the piston chambers) in horizontal position (ports facing upwards) until they start to overflow.

Then seal the ports with plastic or steel plugs.

The equipment must be stored in a well ventilated, dry room. Do not store outdoors.

______________________________________________________________ A6474X235 SVVI/07 3.3

Storage and transport _________________________________________ plastic deformation

In order to prevent plastic deformation of the seal elements, cylinders must be stored in an upright position. Some cylinders must be removed so that they can be stored upright.

random sample inspection

After a storage period of approximately two years, a random sample inspection must be performed to determine whether the measures taken and the method of storage has prevented damage.

On request, the inspection can be carried out by Bucyrus America, Inc.

natural aging

Even with proper storage, seals and hoses are subject to natural ageing. Do not use these parts if they have been stored for more than two years.

HFA fluids

Instructions on the storage of concentrates for hydraulic fluids can be found, if required, in chapter 6 in this operating manual.

Transport Load units; dimensions and weights Observe the transport sheets for the machine and spare parts. They contain information on: ■

dimensions,

■

weight,

■

lifting points, etc.

IMPORTANT! Take care to insure that new supplies are stored separately from existing stock and that removal takes place on the “first in, first out” principle.

________________________________________ Storage and transport Before transport temperatures below freezing

Before transporting the equipment at temperatures below freezing, all hydraulic components operated with emulsion (HFAE or HFAS) must be completely drained and then filled with a corrosion inhibitor/frostproofing fluid.

Transport of equipment at temperatures between -6° F (-21° C) and 40° F (-40° C) is only permissible when certain measures were taken to meet these conditions at the design and manufacture stages. Nevertheless, the individual parts and devices of this equipment must not be subjected to sudden impact loads at such low temperatures and may only be loaded statically or quasi-statically.

© BUCYRUS AMERICA, INC.

During transport of this equipment with floor-mounted vehicles at such low temperatures, measures must also be taken to ensure that the parts and devices are not subjected to sudden impact loads. At very low temperatures and on poor roads, the transport vehicle speed must therefore be limited to a maximum of 15 mph (25 kph) for truck transport. electronic components

Electrical and electronic components must be removed for overseas transport or prolonged storage outdoors unless these components or the complete equipment is protected against harmful environmental influences by a suitable packaging.

The electrical cables remain in the equipment. They must be carefully protected against transport damage and soiling of the connections.

___________________________________________ Major Maintenance Tire/wheel installation procedure The following installation procedures are for general guidance when installing a tire/wheel assembly on most underground mining machines.

Any use made of the advisory information contained herein is entirely within the control and discretion of the user and is wholly voluntary.

WARNING! Mixing parts of different designs or from a variety of sources for wheels with pneumatic tires could cause severe injury or death.

© BUCYRUS AMERICA, INC.

TIRE/WHEEL STRESSES Rubber tired underground mining machinery is routinely subject to severe abuse due to the conditions in which it is operated. Whether a primary haulage or utility/support vehicle, all are subject to extreme shock, vibration, temperature change and various other loads and stresses that cause maintenance problems. One such problem is found in tire/wheel assemblies.

Many maintenance personnel view installing a tire/wheel assembly on a machine as a relatively simple task. However, if a few simple rules on proper installation are not followed, unnecessary difficulties may be experienced. Tires act like shock absorbers on haulage and support vehicles, transferring cushioned loads to the wheels. Even after proper installation, periodic checks need to be made to insure that tire/wheel assemblies do not loosen, causing wheel studs to break or damaging the mounting bolt pattern.

WHEEL MOUNTING ARRANGEMENTS Various mounting arrangements between the wheel and hub or wheel end are used by manufacturers. One of the more common is the taperlock. This arrangement requires a taper on both wheel and hub where the mating surfaces of the taper carry the loads. Incomplete seating of the taper will allow the wheel to loosen, resulting in stud or bolt shear and possible tire/wheel damage.

Another mounting arrangement is based on holding a very close pilot fit where the tolerance between the wheel and hub is very tight, requiring a clamp-load force to hold the wheel securely in place. If the wheel studs or bolts are allowed to loosen, the load will be transmitted to them, resulting in sheared studs or bolts.

PROBLEM AREAS Periodic wheel inspection is critical to the life cycle of a tire/wheel assembly. A fractured wheel, broken bolt pattern and missing or broken wheel studs are all contributors to tire/wheel failures. Problems in these areas occur as the result of repeated cyclical loading as the tire/wheel unit rotates during machine travel. Haulage vehicles loaded unevenly, downhill hauls with high speed turns, or operating a vehicle with one tire of a dual assembly damaged or flat are some examples of conditions that produce damaging high stresses in wheel assemblies. Also, the effects of corroding or poorly fitted mating parts can produce surface irregularities that result in cracks and ultimate failure of a wheel.

______________________________________________________________ A6474X235 SVVI/07 5.67

Major Maintenance ____________________________________________ The most common problem with tire/wheel installations is the incorrect tightening of wheel bolts or studs. Threaded fasteners perform there function of holding things together better when torque control is used in their tightening. Using an accurate torque wrench correctly is the best and most practical way of securing fasteners, Although torque value charts are available as a reference guide to proper tightening, OEM specifications should always be followed when tightening fasteners.

However, proper torque values are of little benefit if certain other factors are not considered.

WHEEL MOUNTING TIPS

Mating surface conditions should also be considered. The tightening surface under the bolt or nut should be carefully inspected. A fastener, when tightened against a softer material, will gall under these conditions, and much of the applied torque may be lost through head friction.

It is very important when using higher strength fasteners to have a smooth, even surface under the bolt head. In some cases, hard flat washers and most lock washers will provide a good tightening surface.

Another area of concern is cleanliness. AlI mating surfaces should be free of rust, dirt, oil, paint, etc. Also no paint of any kind should exist between a fastener and wheel disc surface. Any form of contamination between these surfaces will most likely lead to serious wheel problems.

Fig. 68: Wheel torquing pattern

When torquing any wheel bolt pattern, always torque in a triangular pattern.

All fasteners should be examined before use. Any fastener that is worn, bent or has damaged threads should be replaced. Fastener threads should also be lightly coated with a protective substance, such as residual oils, wax or Loctite, because any oxidation or rust will upset the torque-to-tension relationship.

___________________________________________ Major Maintenance Fig. 69: Torque patterns

Recommended wheel mounting procedures  All steel mating surfaces must be free and clean of any dirt, corrosion, paint, etc. These areas include wheel/hub tapers and disc faces. NO PAINT should be present under bolt heads or nuts.

© BUCYRUS AMERICA, INC.

 Fasteners should be in proper condition. Any fastener with damage, such as corrosion, bending or worn threads, should be replaced. Replace all broken wheel studs.  After positioning the wheel on the hub, tighten nuts down evenly.

Triangulate the bolt pattern tightening sequence as shown in the diagrams.  After operating the machine for a short period of time, check the wheel-mounting bolts or nuts for proper torque.

NOTE: Wheel bolts or nuts “seat in” during normal vehicle operation.

Therefore, it is necessary to repeat torquing procedures as necessary to seat the wheel to the hub. Planned periodic checks will help maintain correct torque values. All bolts and nuts, regardless of type, should be regularly checked for tightness.

Precautions ■

Do not install or remove tire/wheel assemblies from a machine without proper training.

■

Check wheel components periodically for cracks or broken parts.

Replace all cracked, badly worn, damaged, or severely rusted components. When in doubt, replace.

■

Do not, under any circumstances, attempt to rework, weld, heat, or braze any wheel components that are cracked, broken or damaged.

Replace such components with new OEM parts of the correct size and type.

■

Mixing wheel parts of different designs or from a variety of sources is potentially dangerous.

■

Replace broken studs and each unbroken stud next to the broken one.

■ Replace all damaged wheel studs or bolts. ______________________________________________________________ A6474X235 SVVI/07 5.69

Major Maintenance ____________________________________________

_________________________________________________________________ 5.70 Bucyrus – Models 488L and 488-6 UN-A-TRAC®

_____________________________________________ Troubleshooting Troubleshooting procedures The following section lists possible problems encountered when servicing the UN-A-TRAC® and can aid in locating and correcting these problems.

This section covers basic hydraulic components, with each listed in a trouble-cause-remedy format.

For electrical instructions, troubleshooting, and maintenance procedures, refer to the Bucyrus America, Inc. “Motor Controller Solid-State Troubleshooting Guide”.

© BUCYRUS AMERICA, INC.

WARNING! Some procedures must be carried out with the cover of the electrical controller removed and some procedures require the controller to be energized during the tests. It is extremely important that you take all necessary precautions to prevent accidental electrical shock while working within the controller. An MSHA-certified electrician must supervise and inspect all work performed.

For maintenance procedures and tests that DO NOT require the controller to be energized, these precautions include:  Before removing the controller cover, remove power from the system by unplugging the battery.  When the cover is removed, wait one minute for the capacitors to discharge before working inside the controller. To insure that the capacitors are discharged, connect an insulated 100-ohm, 10-watt resistor between the center buss bar and the outer buss bar of the capacitor bank and hold for 30 seconds.  Use insulated gloves and tools where possible.  All connections must be tight and care must be taken to prevent bolts, nuts, washers and other small metal fasteners from being dropped or lost inside the controller. These lost fasteners could cause electrical shorts inside the controller.

For procedures that DO require that the controller be energized while the cover is off:  At no time should you reach inside the controller while it is energized. If it becomes necessary to make adjustments or to replace parts inside the controller, the machine circuit breaker must be turned to the “OFF” position and the capacitor bank discharged (see above). Once the circuit breaker is in the “OFF” position and the capacitor bank discharged, adjustments or parts replacements can be made.  Use insulated gloves and tools where possible.

_____________________________________________________________ A6474X235 SVVI/07 5.71

Troubleshooting ______________________________________________  All connections must be tight and care must be taken to prevent bolts, nuts, washers and other small metal fasteners from being dropped or lost inside the controller. These lost fasteners could cause electrical shorts inside the controller.

WARNING! Never disconnect a hydraulic hose if the circuit is pressurized or there is a load on the circuit. If a hose is disconnected while the cylinder is supporting a load, the load will fall.

___________________________________________ Tightening torques Tightening torques IMPORTANT! Due to the application of fasteners being subject to great stresses and heavy or extreme vibration, it is imperative that all bolts be applied with an adequate amount of torque. For this reason this list of recommended torque settings for different types and sizes of fasteners used has been compiled.

The tightening torques stated in the spare parts lists have to be observed, as well, for installation and maintenance.

© BUCYRUS AMERICA, INC.

NOTICE! Use only lubrication fluids and greases approved by Bucyrus America, Inc. ! These fluids and greases have been tested at Bucyrus America, Inc. and guarantee reliable operation of the mechanical and hydraulic functions of the machine.

IMPORTANT! The lubrication fluids and greases listed in the same table can be mixed. Other products may only be used if the supplier can guarantee that they are equivalent.

Differently composed fluids and greases must not be mixed as this may change the consistency, i.e. the mixture can become thinner so that the lubrication effect is not sufficient. It may also be dangerous to use lubricating greases and fluids having the same specification base but different origins.

In case of doubt, the manufacturer of the lubrication to be used should be contacted as to the compatibility of the lubrication in question.

IMPORTANT! Bucyrus America, Inc. expressly point out that the approval of the listed products relates only to the pure technical use in our mechanical and hydraulic systems. The responsibility for the constituents used in the hydraulic concentrates lies solely with the respective manufacturer.

IMPORTANT! Be sure to use the manufacturer’s instructions for use.

NOTICE! When performing maintenance on the machine, all used oil and lubricants should be disposed of per your local EPA standards.
