THE HUMAN BODY ANDELECTRICAL SHOCK

GENERAL

Personnel safety should be the main concernwhen working with any electrical system or cir-cuit.

DESCRIPTION

Most circuits in any surface mine are of suffi-cient voltage to overcome your body’s resis-tance. Therefore the miner must be able torecognize and avoid coming into contact with anelectrical source.

When a person is electrocuted, he/shebecomes the path of least resistance for theelectrical source to ground and in effectbecomes the part of the circuit.

Properly grounded equipment is the best way toprevent electrical shock. Another effectivemeans is insulation by means of rubber glovesand boots, rubber mats, insulated platforms andguards around cables.

Handling electrical equipment with wethands or while standing in water will causeelectrocution. Handle all electrical equip-

ment in a dry environment.

The killing factor in electrical shocks is current.Current is measured in amps and is determinedby voltage. Ordinary household appliancesrequire currents high enough to kill a person.Current necessary to operate a 100 watt lightbulb is (eight 8) to (ten 10) times the fatalamount.• 5 milliamp (safe)• 8 milliamp (slight shock)• 20 milliamp painful shock• 50 milliamp (very painful shock)• 100 milliamp (possible fatal shock)

One milliampere (ma) is 1/1000 of an amp.

If a fellow worker becomes part of an electricalcircuit and cannot let go of the source, DO NOTrush over and grab him/her. You can becomepart of the electrical shock as well. Instead, dis-connect the power to the circuit. If this is notpossible, remove the person from contact byusing something insulated to PUSH or PULL theperson away while protecting yourself.

In the event of accidental electrical contact callfor help and apply the appropriate first aid mea-sures.

Federal law requires that any repair, installation,or testing of electrical equipment be done by orunder the supervision of a qualified electrician.

DANGER!

Electrical Safety Page 3

All disconnecting devices must be tagged out ofservice prior to work being performed.

Follow any lock out and tag out procedures rec-ommended by the mine site. Do not attempt tooperate the equipment until all lockout devicesare cleared by a shift supervisor(s).

HIGH VOLTAGE powered equipment should bede-energized before and during maintenancework is performed on the electrical systems.

Only electricians specifically trained to workwith high voltage circuits should be permitted toperform electrical maintenance.

Appropriate ground fault management systemsshould be employed at the mine and madeavailable to the specific machine.

Driltech Mission mandates that each minerresponsible to perform maintenance or operat-ing duties on a drill machine utilize the appropri-ate personnel protective equipment - PPEdeemed necessary to perform the duties of thejob or task assigned.

OHM’S LAW and ELECTRICAL CIRCUITS

OHM’S LAW (DC CURRENT)

E = voltsI = amperesR = ohms

Amperes = volts Eohms R

Volts = amperes x ohms E = IR

Ohms = volts R = Eamperes I

FUNDAMENTALS OFELECTRICITY

GENERAL

Basic electrical terms mentioned in the DriltechMission training module are common to theindustry.

DESCRIPTION

The following terms apply to basic electric sys-tems.

• VOLTAGE

• ELECTRONS

• RESISTANCE

• OHMS

• CURRENT

• AMPERES

The following terms are common electrical sys-tem tools used to diagnose electrical compo-nents and the overall system performance:

• VOLTMETER

• AMMETER

• OHMMETER

In simple terms:

VOLTAGEVoltage provides the electrical pressure, orforce that causes the current or electrons toflow. The voltage is the difference in electricalpressure between two points in a circuit. Electri-cal voltage is measured in “volts”.

CURRENTElectrical current is the flow, or movement ofelectrons. This movement can be compared tothe flow of water through a pipe. Without pres-sure (voltage) the current will not flow. Electricalcurrent is measured in amperes or “amps”.

RESISTANCEResistance is simply a restriction of current flow.Increasing resistance reduces current flowwhich can be detected by voltage decreases orloss in the electrical circuit. Electrical resistanceis measured in “ohms”.

VOLTAGE = ELECTRICAL PRESSURE

CURRENT = ELECTRON FLOW

RESISTANCE“OHMS”

CURRENT“AMPS”

Fundamentals of Electricity Page 7

MAGNETIC FIELDA magnetic field is produced when current isforced through a conductor. The magnetic fieldand direction of flow are factors to considerwhen using test equipment such as ammeters.

TEST EQUIPMENTThe use of test meters is an invaluable andessential aid in diagnosing troubles in an electri-cal circuit. If values of voltage, current and resis-tance are not measured with suitable testmeters, only a guess can be made as to whattype of defect exist in the circuit.

VOLTMETERThe voltmeter is used to measure the electricalpressure in the circuit. Analog and digital mod-els are available. It is suggested to use the digi-tal type.

Voltmeters are always connected across (in par-allel with) a part of the circuit.

Voltmeters measure the difference in electricalpotential or pressure between the points wherethe voltmeter leads are attached.

Common 24 volt systems may read (0 - 32)volts.

Common 12 volt systems may read (0 - 16)volts.

AMMETERThe ammeter is used to measure the amount ofcurrent flow. It is suggested to use a digital typeammeter.

Ammeters generally require opening the circuitso the ammeter can be connected in series tomeasure the current flow.

Amps and milliampere are two common circuitflows concerning Driltech Mission products.

OHMMETERThe ohmmeter is used to measure resistance inthe circuit.

Ohmmeters are connected across the unit orportion of the circuit of which the resistance is tobe measured.

The ohmmeter has it’s own power source, usu-ally a small battery or fuse which forces currentthrough the circuit to be measured.

Never connect a ohmmeter to an externalsource of voltage. Battery, fuse or meter move-ment damage may occur.

ELECTRONIC ENGINES

GENERAL

Driltech Mission uses two quality engine manu-facturers:

• Caterpillar

• Cummins

Both suppliers provide service through compe-tent world-wide distributor networks.

DESCRIPTION

The Driltech Mission products require enginehorsepowers that both manufactures are capa-ble of delivering.

Engines manufactured from 1993 to 1995 mayhave been served with either the Woodward orBarber Coleman type speed controls.

In 1995 and early 1996 to present the enginemanufacturers converted to electronically con-trolled engines with high pressure fuel systems

At present all Driltech Mission equipment uti-lizes the electronic fuel systems.

Light indicators at the operator station allow theoperator a means to monitor the engine ECM. Adata link connection enables diagnostic testequipment installation.

In the event that the check engine light is onand the diagnostic indicator light is flashing theoperator should take appropriate measures.

Refer to engine data section of this manual orthe engine specific diagnostic code retrievalspecs.

Crawler mounted operator controls are a desktype panel with hydraulic and electrical systems.

CATERPILLAR 3406E EUIENGINE DATA

SENSOR DESCRIPTIONS

EUI = electronic unit injection fuel system.

HEUI = hydraulic electronic unit injection fuelsystem.

ATMOSPHERIC PRESSURE SENSORMeasures crankcase pressure 0-116 kpa or 0-17 psi (5vdc)Atmospheric pressure sensing is used toreduce smoke emissions at high altitudes.

BOOST PRESSURE SENSORMeasures intake manifold pressure 20-340kpaor 3-49psi (5vdc)Boost pressure is used to reduce smoke emis-sions during acceleration.

COOLANT LEVEL SENSOROptional customer parameter selected.

COOLANT TEMPERATURE SENSORMounted on water outlet housing measures thetemperature of the engine coolant. Coolant tem-perature sensing is used to determine a coldmode operation for 6 cylinder engines. In coldmode timing is advanced and fuel delivery islimited. 3406E engines also have a three-cylin-der cutout feature during cold mode operation.Cold mode operation is activated whenever thecoolant temperature is below 63° F (17° C) andthe engine is not cranking. Cold mode remainsactive until the coolant temperature rises above63° F (17° C) or until the engine has been run-ning for 5 minutes.

FUEL TEMPERATURE SENSORMonitored to adjust fuel rate calculations and forfuel temp power corrections when fuel tempsexceed 86° F (30° C). Max power correction isat 158° F (70° C). Fuel temps exceeding 194° F(90° C) for ten minutes log a diagnostic code.

FUEL PRESSURE SENSORMonitors fuel pressure following engine startfrom 0-690 kpa (0-100psi). With the engine atoperating temperature, typical fuel pressurecan vary from 310 kpa (45 psi) at low idle to 448kpa (65psi) at rated rpm. The fuel check valve isdesigned to open between 413 and 438 kpa,(60-65 psi) to control fuel pressure. The fueltransfer pump has a internal relief valvedesigned to open around 620 kpa (90 psi) Thisvalve will not be open during normal operation.

INTAKE MANIFOLD AIR TEMPERATURESENSORAdjusts injection timing. High intake manifoldtemp warning diagnostic code is triggered at176° F (80° C). Very high temp warning diag-nostic code is at 230° F (110° C).

OIL PRESSURE SENSORMonitors oil pressure in the gallery followingengine start. Pressures from 0-690kpa or 0-100psi. (5vdc)

SPEED/TIMING SENSORDetermines both engine speed and fuel injec-tion timing by magnetic sensor to camshaft con-nection. Primary and secondary units apply(12vdc). If one sensor fails replace both units.

DIAGNOSTIC LAMPCommunicates engine status or operationalproblems. Two digit diagnostic codes are givenwith one-second pauses between code digits. Athree-second pause occurs between codes.Additional diagnostic codes may follow after the3-second pause.

ETHER INJECTION SYSTEMThe engine ECM controls the ether system toimprove the cold starting capability. The ECMuses the Coolant Temperature Sensor to controlether injection. The ECM uses actual enginerpm to determine if ether should be injected.The ether control logic assumes a “continuous”ether system is being utilized and the durationof injection is a linear function of coolant tem-perature. The automatic ether injection circuitturns ON the relay driver when the followingconditions are met. The engine speed must be

Caterpillar Engine Data Page 17

between 30 rpm and 1500 rpm and the coolanttemperature is between –40° to +50° F (-40° to+10° C). The ether injection time is selectedfrom a linear relationship between these tem-peratures. The end points of this function are –40° F (-40° C) for 130 seconds, 50° F (+10° C)for 15 seconds.

Manual ether injection can occur between 30and 1500 rpm if the coolant temperature isbelow 150° F (+60°C) for maximum time dura-tion of 2 minutes. This function is a customersupplied override switch.

DESCRIPTION

Cummins engines detect two types of faultcodes.

There are engine electronic fuel system faultcodes and engine protection system faultcodes.

All fault codes recorded will either be

• active (fault code is presently active onengine) or

• inactive (fault code was active at some time,but is not presently active).

Active fault codes may be read using the checkengine (amber) and diagnostic light (red) on thedrill console. Inactive fault codes may be readwith a laptop only.

To check for active fault codes:

• Turn the key switch to the off position.

• Move the diagnostic switch to the on posi-tion.

• Turn the key switch to the on position.

• If active fault codes are available the checkengine light will begin flashing a three digitcode with one second pauses between dig-its.

The lights will remain off during normal engineoperation.

• Red light on while engine is running, stopthe engine in a safe manner as soon as pos-sible. This fault may be engine disabling.

• Amber light on the engine can still be run butmay loose some system features which may

result in a power loss condition. The failuremust be repaired as soon as convenient.

Cummins engine protection system monitorsthe QSK series engines for:

• High coolant temperature

• Low coolant level (optional)

• Low coolant pressure

• High fuel temperature

• High intake manifold temperature

• Low/very low oil pressure

• High blow by pressure

SENSORS POSITIONED ON THE ENGINE

Some external components will be at differentlocations for different engine models.

Troubleshooting the engine requires a skilledengine technician familiar with electronic fuelsystems.

Three lights positioned on the machine operatorpanel will enable active fault codes to be seenwhen they occur. The sequence of flashes rep-resents the system diagnostic message.

The first sequence of flashes represents the firstdigit of the diagnostic code. There will be a 1second pause between flashes. Codes are in athree digit numeric sequence.

Diagnostic retrieving may be performed usingthe toggle switch labeled increment/decrement.

The specific gravity of the batteries should bechecked between seasons. Ambient conditionswill effect battery capacity when a load isinduced.

Battery life may be affected by:

• dirt

• corrosion

• frayed cables

• overfilling

• loose hold down

• cell connector corrosion

• sealing compound defect

• cracked cell cover

• cracked case

• low electrolyte

Battery test equipment includes a hydrometer.When possible maintain battery electrolyte in a1.270 specific gravity range.

This may be achieved with 64% H2O and 36%acid H SO. Use distilled water as the filling solu-tion.

When replacing a battery cable, cut the cablelength as short as possible and route as directas allowable. Avoid sharp turns and bending.

Pre-lube starter may be fitted to the engine forcold weather operating conditions. The startersolenoid operates a gear pump. Engine oil willcirculate through the engine block to a normalclosed 4 psi (.3 bar) oil pressure switch.

When the start button is actuated prelube willoccur until engine oil pressure opens the switch.There will be a two second pause prior toengine start mode.

Neutral safety and tram alarms are manda-tory for crawler mounted drill machines. Due tothe cable or electronic controls that commandpump displacement a safety interlock is placedon the left and right tram controls that will inter-rupt the machines starting system.

Neutral safety switches are a component of alltram control levers.

Cable operated tram levers have the neutralswitches positioned on the center cam frameand a square pin is positioned on the rotatingcam of the same lever.

Electronic tram controls have a microswitchpositioned on the frame near the rotating cam.

Due to operating conditions and operator com-fort drill machines may be fitted with specificelectrical systems.

These options are a mix of proximity switches,magnetic switches, control relays, and hydraulicsolenoid valves.

The following will be the most common optionsfitted to machine applications.

• Feed override (POS, FRS, FOS)

• Fast feed (FFS)

• Tram interlock (TFS, PVS, LBS, RBS)

• Head/jack/brake interlock (LRP, RRP, FRP,RHU, CR1-4, PVS, LBS, RBS)

• Head loader interlock (FCS, PLP, HIR, FVS)

Options listed are customer specific. Theseoptions may be fitted to machines in the field bycompetent mechanical persons. Installationsmay require minor welding common hand tools,basic hydraulic and electrical system experi-ence.

Feed override

The feed override operating principal is toenable maximum feed pump pressure whenretracting drill pipe from a drilled blasthole.

Dependant on the type of feed pump the maxi-mum pressure allows the pump to be controlledfrom 0 through it’s specific output flow ratewhen maximum pressure is achieved.

Operators select the feed override mode. Thesequence shall start with the feed pump in neu-tral

• apply the pressure override toggle switch

• move the feed control valve to the hoist posi-tion

• select the appropriate feed pump speed withthe feed pump control

Note!When stopping the feed system the feed speedmust be slowed prior to centering the feed con-trol valve or switching the pressure overrideswitch.

The hydraulic valves are situated inside thehydraulic cabinet lower left side corner.

The hydraulic systems for feed vary slightlybetween machine applications. This exampleshows the most common open loop application.

It is preferred that the feed override solenoid beadded after the remote pressure control valve inopen loop piston pump applications.

Confirm feed override solenoid placement onD25KS, D245 and all 90 series machines.

Fast feed

Fast feed is a systems designed to increase thefeed cycle time when extending the feed cylin-der(s) and lowering the rotary head for multi-pass drilling applications.

Operators select this feature with a thumb con-trolled switch attached to top of the feed controlhandle.

Note!The application shall be used to lower the rotaryhead when it is empty of drill pipe.

The sequence for fast feed operation shall be

• select the feed control handle to the downposition

• set the feed pump control to the desiredspeed value from zero through full controlforward

• actuate the thumb control for fast feed

• release the thumb control to resume normalfeed speed

• center the feed pump control to slow thefeed system when preparing to stop orchange directions

• place the feed control handle in the centerposition

Do not use fast feed with drill pipe connected tothe rotary head.

Tram interlock(s)

Crawler mounted equipment that are subjectedto varying ground terrains may require a sec-ondary operator control as a safety feature.

In the drill machine applications the terms dead-man and tram interlocks refer to the secondaryoperator control system.

Most often the tram interlock is a combination ofelectrical and hydraulic valves that enable thepropel pump and final drive brake systems tooperate when conditions are correct.

Components of the tram interlock consist of

• pump vent solenoid

• left brake solenoid*

• right brake solenoid*

• tram foot switch*

• tram interlock junction box*

• control relays*

• proximity switches

Tram interlock may be a basic system or addi-tional relays and switches may be attached foradded machine component safety

The sequence of operating the basic tram inter-lock system

• step on the tram foot switch (TFS)

• operate the tram control levers (LTC/RTC)forward or reverse as needed

• center the tram control levers to neutral posi-tion to stop the machine travel

• step off the tram foot switch

When stepping on the tram foot switch 24 VDCpower will energize the pump vent solenoid andwhen applicable the left and right brake sole-noids.

As the solenoid coils energize the hydraulicspools move, propel pump main pressure isblocked and the servo pressure can release thetrack brake enabling the tram mode.

Tram foot switches and terminal contact pinsare subject to corrosion from work shoes andenvironmental conditions. Clean or replace ter-minal contacts and wire ends as needed.

Applications used with leveling jacks may bejack/brake interloc.

Applications used to protect drill pipe and level-ing jacks may be head/jack/brake interloc.

DEADMAN/TRAM INTERLOCK

TIJB

A tram interlock junction box supports 4 controlrelays, terminal strips a power light and bypassswitch.

Control relays are connected in series with lev-eling jack proximity switches and a rotary headposition switch. The bypass feature may beused during system diagnostic or troubleshoot-ing.

All leveling jacks shall be in the retracted posi-tion and the rotary head shall be up or near thecrown of the mast to enable tram interloc.

With head/jack/brake interloc the sequence ofoperating remains the same as long as thehead and jacks are up.

Hydraulic systems that use independant propelpumps need to supply servo oil to the trackbrake and deadhead system pressure to enablethe machine tram mode.

Tram interlocks may be configured differentlyaccording to machine model and machineoptions. Confirm machine specific serial numberto verify exact electrical and hydraulic connec-tions.

Specific to D25KS and D245S machines theelectrical system is powered through the drillpropel selector switch.

Hydraulic systems that use dual purpose pumps(propel/drill functions) do not supply servo oil to

the track brake meaning brake solenoids arenot required. The pump vent solenoid has todeadhead system pressure to enable themachine tram mode.

If electrical systems cannot apply the hydrauliccomponents the hydraulic system may be termi-nated momentarily for diagnostic purpose. Pres-sure type #4 series hydraulic caps, plugs andunions are required.

Head loader interloc

A feature to protect the rotary head from con-tacting drill pipe loaders is referred to as headloader interloc.

Proximity switches are place in the mast frame,one for each drill pipe loader. The loader bottomsection seat plate will make contact with theproximity switch. Proximity switches are mag-netic sensing and offer a LED light to checksensitivity.

Sensing distance is 3/8 inch (10mm). Wirelength may be cut to fit the application. Deutchconnectors are used to connect switches intothe wire harness.

Proximity switches have three 18 gage wires.One each brown power in, black output to relayor control and blue ground.

The proximity switch black output wire actuatesa control relay circuit that enables or disablesthe hydraulic system feed pump pressure.

The left and/or right loader switch are normalclosed until it senses metal. Upon sensing metalthe loader proximity switch goes open. The feedcarrier switch and head interloc relay are notenergized.

When the feed vent solenoid becomes ener-gized via loader proximity switch and head inter-loc relay, hydraulic pressure through the feedvent solenoid dumps feed pump pressure todrain. This principal stops the feed mode.

Centralizer, vee block and pipe positioner

Machines with extended masts and angle drilloptions use drill pipe guides. The guides areoperator selected. Use the pipe guide or cen-tralizer in full extend or retract positions only.

A drill pipe centralizer is used to stabilize twopiece drill pipe connections when used in a sin-gle pass drill method. The centralizer is placedmid section of a single pass mast assembly.

Vee block and pipe positioner are angle drillaccessories. The intended use is to stabilizedrill pipe during the change procedure.

When the operators use these items for theirintended principal drill pipe alignment will beproper for connecting drill pipe threads.

Caution:The rotary head may come in contact with thepipe guide or centralizer if not full retract orextend position.

A combination of proximity switches, controlrelays and solenoid valves may be used as asafety to protect these items. This circuit willgive notice to the operator that the guides are inposition.

The safety circuit may be a visual indicator lightor it may vent the feed pump to stop hydraulicsystem operation.

Hydraulic systems will vent the feed pump to anear zero pressure and stop the feed downmode until the centralizer position is corrected.

Note!:When the feed pump pressure is near zero thefeed and hoist circuits and lower stacker circuitsare affected.
