Do not attempt to lift this machine with a hoist having less than 2-ton capacity. The shipping weight of the machine including electronics is approximately 2850 lbs.

Do not remove the skid from the machine until it is brought to its final position, especially if the machine is to be moved on rollers.

Once the skid has been removed, place the machine in position on top of the rest pads.

For proper operation, the machine should be set on a substantial floor capable of supporting the weight safely. To secure the machine on its foundation, use anchor bolts. For the location of the bolt holes, size and recommended mounting, see Figure

2-4 for 1440, Figure 2-5 for 1745, and Figure 2-3 for Anchor bolts.

NOTE: Materials for anchoring the machine are not included.

2.10 Cleaning

1. Remove rust protective coating from the machine before moving any slideways

2. The coating is best removed with clean, dry rags. Do not use a cleaning solution that may damage the rubber way scrapers, plastic parts, or paint.

WARNING!

Do not use gasoline or other flammable cleaning agents for cleaning the machine.

3. It may be necessary to move the carriage back and forward and the cross-slide left and right.

CAUTION!

Never move any of the above parts over ways that were not previously cleaned. Serious damage to the TURCITE surface of slideways can occur.

4. Be certain the carriage, cross slide and spindle move freely and smoothly over their entire length.

2.11 Leveling

The precision and durability of the lathe depends on it being leveled properly. Final inspection can be done only when the machine has been correctly leveled.

After the machine is in position on top of the six (6) rest pads, it must be leveled by the use of the leveling bolts. It is important that the lathe be level in order to produce accurate work. It may be necessary to lag bolt the machine in order to eliminate a small amount of twist.

NOTE: The use of a precision level having a minimum accuracy of .0005" over 10.0" will be required.

Move the saddle and tailstock to the center of the bed. To take a reading off the level longitudinally, place the level at each of the four (4) corners of the bedways (Figure 2-6, Positions B & C). To take a reading off the level transversely, place it on top of .7500" parallels at each end of the bedways

(Figure 2-6, Positions A & D).

Maintenance, Safety, & Parts Lists Manual

Use the two (2) exterior leveling screws on the right bottom of the base and the two (2) interior leveling screw on the left bottom of the base to adjust the level of the machine.

Level the bedways longitudinally within .0008" over the total length and transversely within .0005" inches. Once the machine has been properly leveled bring the two (2) exterior leveling screws on the left bottom of the base into contact with the leveling pads using care not to disturb the level.

For a newly installed machine, check the level once every week. Once the foundation is rigid enough, then check it once per month.

2.12 Electrical Connection

The 1745 can be configured for either 220 volts or 440 volts 3 phase electricity. On the other hand, the 1440 can only be configured for 220 volts 3 phase electricity. In order to operate the

1440 under 440 volts you will need a step down transformer, from 440V to 220V and rated at a minimum of 6 KVA.

DANGER!

Be certain that 200-volt electricity (typical range 208 – 240V) is used only with a machine labeled 220 volts and at the electric cabinet, in the back of the machine.

DANGER!

440 Volts will damage expensive electrical components if machine is wired by mistake as 440 volts, when machine is label for 220 Volts. These components are not covered under warranty.

The circuit breaker for the machine should be a minimum of 60 amps.

DANGER!

The 208-240 volt line must originate from a dedicated and independent fused box with a manual shut-off lever. It is the responsibility of the purchaser to supply a wired box that meets all local codes and regulations.

The incoming power is wired to the machine through the electric cabinet located on the back of the machine. The wire enters the cabinet through a hole, from the top right side of the cabinet.

The wire is attached to the electrical strip as follows: the red wire goes to L3, the white into L2, the black into L1, and the ground into the GND. If the spindle motor runs backwards, reverse two of the three wires.

DANGER!

Only a qualified electrician should wire the 220/440 VAC, 3-phase electricity.

Southwestern Industries recommends the machine be earth grounded by driving a copper rod into the ground. It is the responsibility of the customer to install this rod.

Procedure for Converting Motors

For those machines that will be run with a phase converter it must be a rotary type rather than a static phase converter. Rotary phase converters allow for varying loads in the system. The electrical load on the machine will vary based on the type of cut taken and the speed of the motor. Static phase converters can only be used on machines with a non-varying load. The phase converter for the 1440 machines must be rated at a minimum of 6 KVA and the 1745 rated at a minimum of 7.5 KVA.

2.13 Mounting the Display Pendant – Model SL CNC

The ProtoTRAK SL display pendant mounts to the top of the headstock on a stationary tray and is held to an L bracket attached to the tray. (See Section 7, Figures 7-21 & 7-22).

2.14 Cable Interconnections

All cable interconnections are made at the factory except for those connecting to the pendant display. There are a total of 4 cables that need to be connected to the pendant. See Figure 2-

10 for pendant cable connections.

With the main power to the machine turned off plug in the connectors that are bundled on the side of the machine. Each cable mates to only one connector on the pendant display, on the left side of the pendant. Use the key on the pendant to match up the connectors with the correct port. The parallel port will have a key plugged into this port. The monitor port, RS232 and network ports will be left empty during installation.

The machine ID key plugs into the LPT port.

Make sure there is a hardware (option) key plugged into the parallel port of the pendant. This key activates any converters or options ordered. The part number for this key is 22648. The key must be programmed according to the type of machine it is on and the options ordered.

CAUTION!

Make sure the main power switch is turned off on the back of the electrical cabinet before plugging in the cables.

2.15 Lubrication System

2.15.1 Headstock

An automatic splash type of lubrication provides an even distribution of oil to all the gears and bearings in the headstock.

To fill the headstock reservoir to the recommended level, remove the oil cap on top of the headstock cover. Through the hole fill the reservoir to the center of the oil sight gage, located on the front of the machine beneath the speed select lever. Mobile DTE

24 or equivalent should be used.

The headstock gearbox oil must be drained and flushed after the first 150 hours of operation. A small percentage of kerosene may be added to the gearbox to flush out dirt and sediment. Operate the machine for several minutes without load so that the flushing oil can circulate through the reservoir and remove the dirt. The flushing oil must then be drained and new oil added. Do not flush with solvents that will soften the paint. Thereafter, the oil should be flushed and drained every 1000 hours of operation.

2.15.2 Automatic Lubrication Pump

The auto lube system provides centralized automatic lubrication for the cross slide, saddle and ball screws. Flow is proportioned to each lubrication point with appropriately sized orifices. The lube pump’s 2 liter reservoir is serviced with SAE 30 weight oil or

Mobile Vactra Oil #2. The pump’s output can be regulated through a series of DIP switches that control the pause time between pumping cycles, and the duration of the pumping cycle as shown below. Switches are located under the pump control cover.

Pause Time

1 = 2.5 min.

2 = 5 min.

3 = 10 min.

4 = 20 min.

5 = 40 min.

6 = 80 min.

Pump Time

1 = 2.5 sec.

2 = 5 sec.

3 = 10 sec.

4 = 20 sec.

Maintenance, Safety, & Parts Lists Manual

If two or more of the switches are in the “ON” position, the time is additive.

Pause Time Example: 52.5 min. = switch 1 + 3 + 5

LED’s on the pumps’ control indicate operating conditions as shown below:

GREEN = power on

YELLOW = pump operating

RED = warning; out of oil

The pump may also be operated manually with a push button located on the pumps’ control panel.

2.15.3 Tailstock

The spindle and screw are lubricated by 4 oilers located on top of the spindle housing.

The tailstock lock is lubricated with one oiler located on the front face. The bedways on which the tailstock slides should be cleaned and oiled frequently.

For all oilers on the machine, use a medium SAE No. 30 machine oil or Mobile Vactra Oil

#2. Before filling reservoirs or oil cups, always wipe off with a clean rag any accumulation of old oil, grease or dirt that might get into a part being lubricated.

2.15.5 Caution

Do not mix detergent type automotive oil, or multi-purpose oils with the regular grade of

SAE No. 30 lubricating oil.

If calibration factors are being saved, but the measurements are not repeating or are not accurate:

• See Measurements Are Not Repeating

• See Measurements Are Not Accurate

4.3.10 E-Stop Error

The E-Stop turns the power off to the axis and spindle motors. This is done by stopping

110V power from reaching the cable breakout box through the use of a relay in the pendant – SL only.

Once power reaches the cable breakout box it distributes power to the axis motors, auxiliary functions and 110V power to the spindle contactor. If power does not reach the cable breakout box then none of these functions will work.

110V Power reaches the electrical box through the AC E-stop cable. It is used to energize the spindle motor contactor. If this contactor is not energized the spindle will not turn on.

If the E-Stop button is depressed, and no message is displayed on the screen, then either the E-Stop button or the Computer Module is at fault. The 1440 and 1745 have two E-Stop buttons, one on the pendant and the other is located on the forward/reverse switch box.

Does 110 V power come out of the cable breakout box power cord on the pendant? If yes and the screen has an E-stop message then replace the pendant.

Check cable breakout box power cable and the AC Estop cable connection on the cable breakout box and electrical cabinet.

If spindle comes on, the problem is in the computer cabinet.

4.4 Problem with the Measurements

4.4.1 X and Z-axis Measurements Do Not Repeat

With a dial indicator mounted to the bottom of the spindle, touch off a fixed surface either in the X or Z-axis direction and then set the DRO equal to 0. Crank away several inches and then touch off again at the same place. If the reading has not returned to 0 on the DRO, zero the display and repeat the procedure. If the measurement does not repeat, you have a repeatability problem that must be resolved.

Test for accumulative error by moving the axis a number of times to see if the error gradually grows by a small amount. If the error abruptly changes by a large amount it may be caused by a bad encoder.

Expected repeatability numbers should be 0.0005” or less.

Possible Cause Check This

Machine Tool & Setup problem

X and Z-axis Gibs are loose

Check for any looseness in the setup. See Machine Tool

& Setup Section 5.1.

Check the adjustment of the X-axis Gib using the X-axis

Gib adjustment procedures. See section 6.2.1.

X and Z-axis Drive Trains are loose Check Repeatability using the Repeatability and Positional

Accuracy procedure. Step by step, carefully inspect the

Drive Train for any looseness. It may be necessary to disassemble and then reassemble the Drive Train. See

Mechanical Drive Train (X, Z) Section 5.2.

Encoder Disk or Reader Head on motor are loose

SL only – Swap the motor in question with a known good motor. For example, swap the X-axis motor with the Zaxis motor. If the symptom stays with the motor in question, then replace the motor. If not, then the motor is not at fault and something else is causing the problem.

4.4.2 X and Z-axis Measurements Are Not Accurate

Measurements repeat, but with a dial indicator mounted to the spindle, traversing the length of a gage block or some other measurement standard, the measurement is not accurate.

Note: If your part has incorrect dimensions, see Parts Have Incorrect Dimensions,

Section 4.1.4.

Note: First check for repeatability of the DRO: With a dial indicator touch off a fixed surface either in the X or Z-axis direction and set the DRO equal to 0. Crank away several inches and touch off again at the same place. If the reading has not returned to

0 on the DRO, zero the display and repeat the procedure. If the measurement does not repeat, you have a repeatability problem that must be resolved before the accuracy problem can be resolved. See Measurements That Do Not Repeat, Section 4.4.1.

Possible Cause

The Calibration is incorrect Recalibrate the machine.

Do This

See Calibration & Backlash Constants

Incorrect backlash values If the machine does not repeat bi-directionally check the backlash on the axis in question. See Calibration and

Backlash Constant Section 6.2.2.

4.4.3 The DRO Is Not Counting

Code 33 Software Identification. This is needed if you call SWI Customer Service.

Code 100 Axis open loop test. Used to check the maximum feedrate of an axis and if the encoders are counting.

Code 132 Electronic handwheel test

Possible Cause Check This

Electronic handwheel failure Each handwheel should count 0.100” per revolution in both directions in fine mode and 0.8400” per revolution in course mode.

Servo driver failure Check the LED status on the axis in question. See Servo driver

Section 5.5.

Motor Encoder not counting See Motor diagnostics

Computer/Pendant failure See Computer/Pendant diagnostics section 5.3.

4.4.4 X and Z-axis DRO Counting in Wrong Direction

The DRO is counting in the wrong direction. For 1440P/1745P and 1440/1745 Sport, use code 97 to configure the direction of the count.

The positive directions for each axis are:

X-axis – cross slide moves toward the operator

Z-axis – carriage moves toward tailstock

Do the following service code and procedures:

4.5 Problems with the Machine Tool

4.5.1 Spindle Stalls or Turns-Off during Machining

During machining, the spindle turns off and loses power. First check incoming voltage and connections.

Possible Cause

Machine Tool and Setup problem

Motor drive Belt is slipping

Cut more than the machine is capable

Overload Relay has tripped

Check This

Check the type of material being cut, type and size of cutting tool, RPM, and Feed rate. Also check the condition of the cutter to verify that the cutter is not dull. See Machine Tool &

Setup Section 5.1.

Check the alignment, condition, and tension of the Drive Belt.

Check speeds, feeds and depth of cut

Check the overload relay on the electric panel, label OLS-1, reset the relay to see if the spindle will turn back on. If not check the three 40 amp fuses in F1, F2, and F3 for continuity.

4.5.2 Spindle Motor Hums or Will Not Run

The spindle motor makes a constant humming noise during operation or will not turn on.

If power is not reaching the electrical cabinet, but is reaching the cable breakout box, then most likely a relay has failed in the cable breakout box. The cable breakout box will need to be replaced. This relay is in series with the 110 V power in the E-stop circuit. If power has reached the electrical box then use the schematic in figures 2-7 and 2-8 for how the power is routed.

Possible Cause Check This

Check the 220V/440V voltage to the machine Wrong voltage

Poor wiring connections

Defective cables or poor cable connections

Check all the wiring connections to the electric’s box.

Check all cable connections

Leveling is one of the most important aspects of setting up the machine properly.

Improper leveling can lead to a variety of machining problems.

The machine should be level to within .0008” longitudinally and .0005” transversely. See

Leveling Procedures, Section 2.11.

If vibration or chatter continues to be a problem after all other variables have been covered, it is highly recommended to lag bolt the machine down to the floor.

Lag bolting should be down by an outside contractor. There are a lot of variables that need to be taken account of before the process begins. The contractor must look at such things as the floor capacity and the building foundation. SWI is not responsible for lag bolting a machine down.

5.1.2 A Special Word about the X Gib

The X gib is vital to the performance of your lathe.

Gibs should be:

• flat

• free of twist

• free of burrs

• free of blockages in the oil passages and channels

Defective or scarred gibs must be replaced. Shimming of gibs will not yield acceptable results.

It is good machining practice to avoid the use of shop air to clean the chips off a machine. This risks blowing chips into the sliding way surfaces and compromising the performance of the machine.

See Gib Adjustments, Section 6.2.1.

5.1.3 Lubrication

Lubrication is one of the single, most important maintenance issues and plays a key role in assuring the performance and durability of the lathe. At the beginning of each day manually supply oil to the way surfaces by manually overriding the oil pumping in the back of the lathe.

Lack of lubrication can lead to a variety of problems with your machine motion due to increased friction in the sliding ways. This increased friction may lead to part inaccuracies and decreased life expectancies of your ballscrews and way surfaces.

Maintenance, Safety, & Parts Lists Manual

Make sure the oil pump for the headstock is working properly at the start of each day.

Check periodically the site glass for the headstock oil, the site glass is located around the gear selectors. Lack of lubrication in the headstock can lead to increased wear of the gear train as well as premature wearing or failure of the spindle bearings.

5.1.4 Machining Set-Up

The machining set-up itself is always something that can greatly influence the performance of the lathe. The following are some things to keep in mind.

Problems With

Feed and Speeds (spindle rpm)

See below

Tooling

Using the wrong cutter for an application

Cutting too deep

Can Contribute To:

Poor finish

Excessive speeds and feeds can break cutting tools or wear out too fast.

Poor finish

Parts incorrect

Part dimensions incorrect

Driving and cutting forces cause deflections, since no material is totally rigid

Poor finish, decrease the life of the cutter No coolant

The following is a list of common machining problems and some possible solutions.

Problem

Poor surface finish

Long workpieces out of round

Excessive chatter

Check or Try This

Dull tool

Reduce feedrate

Increase spindle speed

Use a higher rake angle tool

Make sure tool is not dull or chipped

Use proper grade of cutting tool

Use coolant

Check to see if tools are on the centerline

Use a follow or steady rest

Tool bit improperly ground or not on center

Avoid extreme negative rake inserts

Tool overhang too great, tool deflection

Improper feeds and speeds

X gib loose. See Gib Adjustment, Section 6.2.1

Work improperly supported

Machine tool out of level - See Leveling Procedures,

Section 2.11.

5.1.4.1 Spindle Speeds

Spindle speeds are influenced by a number of variables:

• Material

• Rigidity of the Machine Setup

• Coolant

• Insert, geometry and material of insert

• Depth of cut

Maintenance, Safety, & Parts Lists Manual

5.1.4.2 Feedrates

Factors that affect feedrates:

• Depth of cut

• Design or type of insert

• Sharpness of the insert

• Workpiece material

• Type of finish or accuracy required

5.2 The Mechanical Drive Train (X, Z)

Indications:

• Troubleshooting instructions indicate that the drive train is potentially the problem and other, more easily checked, variables have been exhausted.

• Roughness, looseness, tightness or jamming movement in the carriage or cross slide.

• Carriage walk-up due to Z ball screw misalignment.

1. Check for machine considerations, especially X gib adjustments and leveling. See

Gib Adjustments, Section 6.2.1.

2. Do the following special service codes:

Code 12 - this is a procedure that helps the control adjust to the friction characteristics unique to the machine. Write down the resulting values from the display. If your problem is control related, check to see if this procedure has resolved the problem.

3. The torque required to manually turn the X and Z-axis ballscrews should be between

10 to 15 in-lbs. These values should be consistent in both directions and along all areas of the axis travel. Values that differ from that of above may correspond to misaligned ball screws.

The following steps take you in a logical sequence through the assemblies. If the step doesn’t isolate or resolve the problem, it will be necessary to disassemble the indicated item and move to the next step. See Figures 7-4 and 7-5 in section 7.0.

4. Ensure that the screws that hold the bearing housing in place are not loose.

5. Ensure that the Clamp Nut is secured. The following applies to the clamp nut: When loosening, make sure to back out the 10-32 screw from the clamp nut.

6. When tightening, snug the 10-32 screw to keep the clamp nut from spreading, tighten it again after the clamp nut is tight.

7. Take out the angular contact bearings in the X & Z-axis and inspect them. They should roll smoothly and be lightly greased.

NOTE: The bearing housing and spacer rings are matched sets - keep them together.

8. With the motor and drives removed, inspect the ball screw, ball nut and yoke for the potential problems shown in the chart below.

Maintenance, Safety, & Parts Lists Manual

CAUTION!

Unlike a leadscrew, do not unscrew the ball screw from its nut. This will destroy the ball screw!

Potential Problem: Check By:

Bad ball screw

Ball nut not tightened to the yoke

• Visual inspection of the ball nut - if the nylon seal is broken or deformed, if contamination has visibly entered the ball nut or if balls are out of the ball nut, replace the ball screw.

• Cranking the ball screw through a significant part of its travel. If it jams, feels loose, or has rough spots, replace the ball screw.

• Dial indicator on a vertical flat of the ball screw indicates backlash between the ball screw and ball nut.

• Inspection for space between the head of the bolt and the ball nut i.e. the retaining bolt has bottomed out in its thread and is not securing the ball nut to the yoke properly.

Yoke loose in the carriage

• Inspection for any motion of the yoke or looseness in the Yoke mounting screws.

Oil lines sheared • Visual inspection.

Oil line blockage • Pump the oil and ensure that it flows evenly to the ways, ball screws and crossslide.

Z Ball screws not aligned properly

• Manually turn the ball screw through the length of its travel. Pay particular attention to the movement near the headstock, the middle and the tailstock.

NOTE: Ball screws are inspected throughout their entire travel for backlash and consistent torque. A ball screw should be good for millions of inches of travel if installed properly. Do not be too quick to replace a ball screw if there is insufficient indication that it is bad; this will just be a costly delay to resolving the real problem.

5.3 Computer/Pendant Diagnostics –

5.3.1 Computer/Pendant – Model SL

The pendant consists of 3 separate modules: the computer module, flash drive module and the LCD screen enclosure.

In general, the pendant/computer module is best diagnosed by eliminating all other possible alternatives. The following table lists some problems and what these problems can lead to.

Possible problems

Poor cable connections

Can lead to

Pendant locks up

No voltage to RSG port

Low voltage to flash drive or slave board.

Flash disk failure

Floppy disk failure

LCD backlight burns out

Faulty E-stop switch

Overlay failure (keys on pendant)

Low voltage to pendant or current spikes

Slave board not functioning

There are 4 cable connections to the left side of the pendant. Make sure all cables are properly fastened.

Press the E-stop button and see if lock up clears if not then do the following:

Turn the pendant off, wait at least 30 seconds, and turn it back on and check to see if the malfunction has been reset.

RSG will not work – should be 5 DC volts present

Check with a voltmeter.

Can cause the system to lock up and the flash drive to act abnormally.

Check voltage to power cable at flash drive module with voltmeter. It should be 4.8 DC volts and above. Lower values than this can cause problems.

If the flash disk fails, the system will not boot up or operate. It will need to be replaced. All programs and machine configurations will be lost. Make sure to back up your flash drive from time to time. Only the flash drive module will need to be replaced.

Will not allow user to save or pull up programs from a floppy disk.

Can the floppy drive format a disk? See Checking Floppy Drive Section

5.3.5.

Check all cable connections to LCD, distribution board and computer module. Make sure the power is turned off before doing so.

It can be stuck open or closed (pressed). If it is stuck closed the pendant will need to be replaced because the user will have no way to get rid of the message. If it is open it will allow the machine to still operate but it will be unsafe for the user. The pendant will still need to be replaced.

Certain buttons on overlay do not work. Do code 81 to verify each key beeps.

1 amp fuse in pendant blows. Pendant will not turn on.

Machine will not run. If under Code 33 it says “Firmware Edge,” it means the slave board is not functioning.

5.3.2 Computer/Pendant – Model L2

In general, the Computer/Display problem is best diagnosed through a process of elimination. The following steps can be taken to help this process:

52

TRAK TRL 1440P, 1745P, 1440S, 1745S, and Sport 1440S, & 1745S Service, Installation,

Maintenance, Safety, & Parts Lists Manual

1. Make sure there is good 115V (range 110V to 130V) electricity servicing the control.

Check the connector at the computer/display back panel.

2. Turn the control off, wait 2 minutes, and turn it back on. Check to see if the malfunction has been corrected.

3. Unplug the X and Z motor cables at the back panel. Also, unplug the remote stop/go push button if you have this option. Input a program and activate the

Simulation Mode using Code 22. The Simulation Mode allows a program to run without actually driving the motors and moving the table or saddle.

4. Input and run a program. If you cannot do this successfully, the computer/display must be replaced.

5. If the control runs properly in the Simulation Mode (step 3) but not with the motors connected as a complete system, use Code 89 to cancel the Simulation Mode and double check the drive train and motor/servo subsystems.

5.3.3 Pendant (Model LX2)

Symptoms

1. Display screen blank

2. Keys do not respond

3. “Bad” picture on screen

Diagnostics – Nine bar test

1. With power on, disconnect the logic cable on the back of the pendant

2. There should be nine horizontal yellow bars displayed on the screen and all the keys should ‘beep’ when pressed

3. If the pendant fails this test, ensure that 110V power is getting to the pendant and both fuses in the back panel are good, then replace the pendant

5.3.4 Computer

Symptoms

Problem such as “blank display screen” is manifested on the pendant, but the pendant passes the nine bar test.

Diagnostics

1. Check incoming 110V power to the computer module

2. Check both 5A and 8A fuses

3. Check that E stop is not engaged

4. Check that red light close to the fuses is lit. This indicates whether the motor/servo assembly is receiving power

5. Check that top red light (1 of 3) on computer module is lit

Purpose of all LEDs

Top: Indicates power to motherboard

Middle: Indicates the system is receiving counts from the motor or independent encoder

– should be seen whenever the axis is moving.

Maintenance, Safety, & Parts Lists Manual

Lower: Indicates that the slave board is sending a command to move the motors – should be seen while attempting to jog an axis.

Failure of these lights to come on during the speed feed operation, indicates that the computer module should be replaced.

5.3.5 Checking Floppy Drive by Formatting a Disk

1. Find a new disk and install in floppy drive.

2. Install keyboard into middle port.

3. Press CTRL ESC to get to start menu.

4. Press R for run.

5. Type Format a: - press enter.

6. If the format works your disk drive is working. If format does not work, reboot control and see if it now works. If it does not work replace the computer module.

7. Press ALT ESC to get back to PT4 software.

5.4 Motor Diagnostics

The Motor subsystem is comprised of 2 parts: The Motor Encoder and the Motor. The motors are powered by 110 VAC voltage. The servo driver is also an integral part of servo system, which is discussed in detail in the next section.

WARNING!

Do not work with the motors unless the power is disconnected from the machine. The motors are run by 110 VAC. There is possibility of death by electrocution!

Rarely do both the X and Z motor/servo systems fail at the same time and in the same way.

So, if your problem is occurring on both axes, its source is probably somewhere else.

5.4.1 Cable Connections

Check the motor cable connections on the cable breakout box. Verify there are no pushed in pins on the connector.

5.4.2 To Check the Motor Encoders

If the motor encoder inside the motor has failed or is not reading the machine will fault out on that axis. Do the following to verify this problem:

Run Service Code 100 or 131. This will display on the DRO if the motor encoder is counting.

If this axis does not count, the encoder is not counting. This means either the encoder or the cable is the problem. Visually check the cable for any problems. If the encoder has failed the motor must be replaced.

5.4.3 Encoder Counts to Pendant

Before replacing the motor due to a bad motor encoder it is a good idea to check the cables that take those signals back to the pendant. If these signals are not getting back to the pendant then the axis will fault. Check the following cable connections.

• Umbilical #1 and #2 at the encoder module

54

Southwestern Industries, Inc.

TRAK TRL 1440P, 1745P, 1440S, 1745S, and Sport 1440S, & 1745S Service, Installation,

Maintenance, Safety, & Parts Lists Manual

• Umbilical #1 and #2 at the pendant

• Umbilical #1 carries the X-axis signals and Umbilical #2 carries the Z-axis signal.

5.4.4 Moving Problem from One Axis to Another

Another way to troubleshoot a problem with a particular axis is to swap parts from 1 axis to another to see if the problem moves. If the problem moves then that component is faulty. See the example below.

Symptom – X Axis will not move and faults

This particular problem can happen because of any of following reasons: bad motor, servo driver, power cable, or computer module. In some cases it is not always obvious which component is causing the problem. This example will help us pinpoint the problem through a trial and error process.

Let’s assume we have narrowed it down to the servo or electrical systems and the Y-axis has no problems. Lets also assume it is not an obvious problem like a loose connection.

This particular example was done on a machine with motor encoders only.

Swap these components

Physically switch the X and Z motors

Results

Has problem moved to Z-axis? If yes, replace motor. If no, the motor is not the problem.

5.5 Servo Drivers

Indications:

• Problems moving just one axis. The axis faults out on the screen.

Servo Types:

• X is a light duty driver

• Z is a heavy duty driver

Steps:

1. Turn off and unplug the system.

2. Check all connectors in the computer cabinet.

WARNING!

Do not work with the Servo Driver unless the power is disconnected from the machine. There is possibility of death by electrocution!

Note: To avoid pulling the wires out of the connector, use the loop to pull the connector from the Servo Driver.

If the problem moves to the other axis and clears up from the original axis, replace the

Servo Driver.

5.6 Electrical

5.6.1 Checking A/C Voltage

This procedure tests for the 115V power for the control.

• Use a Voltmeter, reading A/C volts.

55

Southwestern Industries, Inc.

TRAK TRL 1440P, 1745P, 1440S, 1745S, and Sport 1440S, & 1745S Service, Installation,

Maintenance, Safety, & Parts Lists Manual

• Acceptable range is 110V to 130V

Note: systems running consistently close to the high or low values may have problems when normal voltage fluctuations push the voltage out of the acceptable range.

Our 1745 systems are shipped ready for either 220 VAC or 440VAC, and the 1440 is only setup for 220 VAC of power. The transformer secondary tap is set on 115 volts.

Measure the voltage coming out of the transformer by placing the voltmeter across the

115 V and 0 V taps. If this measurement is above 120 volts then move the tap from 115

V to 110 V. If the reading is low, 110 V or below, then change the tap from 115 V to

124 V. Input power to the machine that is 230 V or above will cause the 110 voltage to be high and voltage that is 208 V or below typically causes 110 voltage to be low.

WARNING!

Turn the main power off before changing the taps on the transformer. Failure to do this can possibly cause death by electrocution!

5.6.2 Checking Fuses

There are 12 fuses that make up the system on the 1440 and 1745. There are (2) two fuses in the pendant and (10) ten fuses in the electrical cabinet.

To check fuses:

1. Use a Volt/Ohmmeter; select “OHM” or “ Ω”.

2. Remove the fuse completely from the pendant display or computer module.

3. Place a lead of the meter on each end of the fuse.

• A good fuse reads 0 (zero) or close to it.

• A bad fuse reads Open or Infinity or OL (overload).

5.6.3 Fuse Indicator Lights

LED lights are used to signify that there is power reaching certain components. The cable breakout box, lube pump, and floppy drive have an LED light. LED lights will only come on when the devices are in operation. If they do not come on when they should, check the fuse next to the light. If the light is still off, move further up the connection line to see if there is break in other parts of the line.

5.6.4 Cable Breakout Box Connections

The Cable Breakout Box is located below the two servos (See Figure 6-1 for models L2 and SL). The list below describes what takes place through each connection. Power reaches the cable breakout box through AC IN from the pendant. From there power is distributed through the system.

Umbilical #1 & Umbilical #2 Ports (To Pendant) - The lathes have (2) motor encoder signals that are communicated between the Encoder module and the

Pendant by use of (2) Umbilical cables. The X signal is communicated through umbilical #1 and the Z motor signal is transferred through umbilical #2.

Apron Port - Communication for X & Z-handwheel and jogstick logic signals between the Pendant and the cable breakout box.

Maintenance, Safety, & Parts Lists Manual

X & Z- Servo Ports - This port is used to receive power and logic signals from the

X and Z- servos.

X & Z - Motor Ports - are used to receive power from the servo and distribute it to the motors.

X & Z-Motor Encoder Ports - These ports are used to receive logic signals from each of the X & Z-Motor Encoders.

Spindle Encoder Port - The port is used to receive logic signals from the spindle encoder, when it is engaged for a threading routine.

Logic to Servo (PWM) - This port is used to keep continuous feedback between the servos and the cable breakout box.

110 VAC Outlet - The outlet is for powering up the coolant pump. Beside the outlet is an LED light signifying power is reaching the pump when it is active, and a fuse to protect the pump.

E-Stop and Spindle Out Port - used to disable power to the spindle motor when the E-Stop is activated.

5.6.5 Cable Connections

The lathe machines use several cables to communicate between systems. It is often the case that what appears to be the failure of an electrical component is actually attributable to a poor connection.

Indications:

• Control problems, chronic or intermittent.

• Motor problems

• Measurement problems

Explanation:

1. Turn off and unplug the system from the wall.

WARNING!

Do not plug and unplug connectors with the system power on. This may cause damage to the connector board and harm to the technician.

2. Visually inspect the connections for excessive debris, moisture, or obvious damage.

3. Carefully clean any chips away from the connectors.

4. One-by-one, take out each connector and then plug them back in. Do the same at the computer/display.

5. Make sure the screws are tightened on each of the connectors.

5.6.6 Electrical Box

The purpose of the electrical panel is to distribute power, protect the system, and relay switches.

The electrical panel fuse and distribute 220 VAC 3 phase power from the power strip to the spindle motor. Also, 220 VAC single-phase power is input into the transformer to produce 110 V single-phase power, which is directed to the pendant.

The system is protected by a series of fuses. The 220/440 volt system, respectively, has (3)

40/20 amp fuses to protect the spindle motor and (3) 6/4 amp fuses to protect the coolant pump; two of which is also to protect the transformer. It also has (1) 4/2 amp fuses to protect the spindle magnetic braking system and (1) 8/4 amp fuse to protect the pendant.

The power module also consist of relay switches: the spindle forward /reverse switch

(K1/K2), E-stop Latch (K8), coolant pump trip (K4), brake timer (KT-1), and the Overload Trip

(OLS). The 1440 will also include the HI/LO switch for the spindle motor relay (K5, K6, and

K7), which is not present in the 1745. See Figure 5-1 – Power Panel.

5.7 Door Interlock Switch

The 1440 and 1745 both use a door interlock switch to verify to the control that the door is closed in various modes of operation. This switch is wired normally open but is forced closed when the door is closed during CNC run mode. There should be continuity between pins 1 and 6 when the switch is forced closed and no continuity when the switch is in the open position. See

Figure 7-3.

The following codes pertain to software functions in the control. To get to any of these codes go to Service Codes, press “A” and press the code you wish to view.

Note - If you are working with the SWI Customer Service Group, write the values down for Code 33 or Code 313. These values will be valuable for troubleshooting.

5.8.1.1 Code 33: Software ID

Code 33 is the software identification procedure. The two types of software in the control include:

Software Version - the version of the system you have installed

Firmware Version - the version of firmware software that is responsible for control to servo interface.

5.8.1.2 Code 37: RS232 Baud Rate

This code sets the baud rate for RS232 applications. The recommended baud rate is 9600.

The following baud rates can be chosen: 4800, 9600, 19200, 38400, 57600, 115200.

5.8.1.3 Code 141: Load Configuration file from floppy “A” drive

This code allows you to load your configuration file from the floppy disk to your hard drive. The configuration file consists of items such as calibration and backlash constants. This code is used when a computer module or hard drive has been replaced.

5.8.1.4 Code 142: Save Configuration file to floppy “A” drive

This code allows you to save your configuration file to a floppy disk. The configuration file consists of items such as calibration and backlash constants. This code is used when a computer module or hard drive needs to be replaced. This stores the configuration file from the hard drive to the floppy disk. It is a good idea to do this code after the machine is initially setup so these values can be saved and used in the future. If the computer or hard drive fails, then you will not have the ability to save the configuration file and the machine will need to be re-setup when the computer or hard drive is replaced.

Note: All machines will have a copy of the configuration file in the back of the electric’s cabinet.

5.8.2 Machine Set-up Codes

The following codes are used primarily when setting up a new machine. To get to any of these codes go to Service Codes, press “B” and press the code you wish to view.

5.8.2.1 Code 12: Feed Forward Constant

The Code 12 procedure helps the control “learn” the friction characteristics of the machine by sending a graduated series of motor signals and observing the results. The process takes less than 30 seconds to run. It is both a diagnostic routine that displays values, and a routine that sets the parameters of the control for the particular machine.

The Code 12 is used for diagnosing and resolving:

• Problems with machine motion.

• Machined parts come out bad – especially poor finish.

Note: Code 12 routine will set the parameters for the particular machine and its particular situation. If the machine changes its friction characteristic, the Feed Forward

Constant should change too, or the system will not servo properly. Whenever gibs are adjusted or a heavy workpiece has been added to the table, you should run a Code 12.

When the heavy workpiece is removed, Code 12 should be run again.

1. Position the table and addle in the center of travel. Note: You will lose your DRO position reference.

2. Go into the Service Codes and input the Code 12.

3. Press

4. The system will run the routine automatically and then display values on the position readout.

Explanation

Typical values should be between 4.04 and 11.11 are considered normal for each axis.

Higher values indicate excessive friction in the system. Lower values indicate a loose system and may mean a gib adjustment is necessary. Value 4.04 means the friction is a factor of 4 in one direction, and 4 in the other direction. The values should be within 3 or 4 of each other in both directions. A value of 6.08 would still be considered normal.

On S products, do not equate Code 12 values to torque on ballscrew. Measure friction in system with an in-lb torque wrench.

The feed forward gain can be adjusted manually by pressing the manual button. Choose the axis you would like to change and then enter values in the positive and negative direction to adjust. Adjusting the gain can help solve circularity problems. Default values can be set by pressing the Reset button. The manual feature should only be used in extreme cases where the AUTO routine did not solve the problem. Manual adjusts above 12 may lead to servo related problems.

5.8.2.2 Code 100: Axis Open Loop Test

Code 100 procedure is used to diagnose problems with the configuration of the system, the encoders and incoming A/C voltage.

IMPORTANT -- SAFETY NOTICE

During this procedure the designated axis will be given a command to move at maximum speed for 1 second in the direction you choose. Avoid crashes by starting with the cross-slide and saddle centered. MAKE SURE THAT NO ONE IS STANDING IN THE WAY OF THE CROSS-SLIDE

OR SADDLE!

Note: You will lose the DRO reference position.

This procedure is to be run for each axis that is servo-driven, and for both the plus and minus direction for each axis.

1. Center the cross-slide and saddle.

2. On the Pendant display, go into the Service Codes and input the Code 100.

3. The conversation line will say: “SELECT AXIS”. Input the axis. Either X or Z.

4. In the conversation line it will say “WHICH DIRECTION? PLUS”.

• If you want to run in the plus direction, press INC SET.

• If you want to run in the minus direction, press +/-, then INC SET

5. In the conversation line it will say “PRESS GO”. Press Go after you are sure that the machine will not crash in the direction and axis that you have specified.

6. Afterward the screen will display values next to the DRO position axes

Interpretation of the resulting values displayed:

The values for the encoder displays should be in the range of 3.0000” to 5.0000”.

• If the motor encoder value is not within specification it may be the problem. If the encoder is not reading then it will need to be replaced.

• The feedrate should be a minimum of 180 ipm. Shops with higher voltages will see higher values.

• If the feedrate is less than 180 ipm and inconsistent in both directions, check the incoming AC voltage and mechanics of the drive train.

• If the feedrate is very different on the same axis for + and -, then the torque on the axis that is tested maybe higher than 15 in-lbs. Typical torque values on machines that have the ball screw aligned and the gibs adjusted to specification should be between 10 to 15 in-lbs. This will produce code 100 values within 50 ipm in the positive and negative directions. Machines that have an axis torque of 20 in-lbs may see a deviation of 75 ipm. If the code 100 values exceed this deviation then the axis torque is too high. Align the ball screw or adjust the gibs.

5.8.3.1 Code 54: Program Continuous Run

This Code runs a program continuously without stopping for tool change commands. It is helpful in running a long period to identify an intermittent problem.

1. Prepare a program as you normally would.

5.8.3.2 Code 81: Keyboard Test

This code is used to check if the keyboard is functioning correctly. It allows you to test each key on the pendant individually. When you press the keys, the corresponding box for that key will highlight on the screen. The pendant will also beep, indicating that the key is working correctly. If one of the keys does not work the pendant assembly may need to be replaced. If none of the keys are working chances are that the computer module will need to be replaced.

5.8.3.3 Code 131: Manual DRO

A manual diagnostic routine to check the motor encoder and table encoders. Turn the X hand wheel to display the encoder readings. This code will display the actual DRO counts and the raw encoder counts before the calibration and backlash factors have been factors into the counts.

5.8.3.4 Code 132 - Electronic Hand wheel Test

Turn the X or Z-axis electronic hand wheel. The display should show movement as the hand wheel is being turned. There should be no skipping and it should count smoothly while the hand wheel is being turned. One revolution of hand wheel should read

0.4000” for Z and 0.1000” for X.

5.8.3.5 Code 133 – Spindle Encoder Test

Turn the spindle or run the spindle at low RPM’s. The display should show the counts from the spindle encoder. It should count to 360 on the Z display and then reset. Each time it resets it displays the number in the X display area.

14. Retighten the yoke.

15. Move the ball screw manually and move the carriage through the entire length of the Z-axis. Pay special attention to the areas near the headstock, tailstock, and in the middle of the travel. If there is any binding or rough spots, the alignment procedure must be repeated. The axis should feel equally free throughout the entire range.

16. Using a torque wrench, measure the torque to move the z-axis at each end, and in the middle of the axis travel. The torque reading should be a maximum of 10-15 in-lb.

6.1.26 Headstock Taper Adjustment

The headstock may be adjusted to remove turning taper if the taper is caused by a lack of parallelism of the headstock to the bed ways. Ensure that the level of the bed is correct prior to any headstock adjustments.

To adjust the headstock alignment, loosen the four socket head cap screws that attach the headstock housing to the bed. Using the adjusting screw located at the rear of the headstock, (see Figure 6-8) adjust the headstock position in the direction necessary to remove the taper. Note that the headstock will pivot about a pin located between the two front attaching screws. Tighten the attaching screws and test for taper.

rolling torque is around 10 in-lb. Note that the torque required to start (“breaking away torque”) the spindle’s rotation will be higher.

3. If torque is out of tolerance. Open rear headstock panel to gain access to adjusting nut at the rear of the spindle shaft and loosen the three setscrews, so that you can adjust the load on the bearings accordingly (Item 4, Figure 7-6 for 1440 & Item 4

Figure 7-9 for 1745).

4. Torque too low: Lock the spindle in low gear. With a spanner wrench tighten the adjusting nut. Return the speed selection lever to the neutral position. Measure the rolling torque and repeat until 10 in -lb. of rolling torque is achieved. Tighten the three setscrews to retain the adjustment.

5. Torque too high: Lock the spindle in gear. With a spanner wrench loosen the adjusting nut two full turns. Place an aluminum block over the end of the spindle and with a hammer drive the spindle forward until it is loose. (Near zero rolling torque)

With a spanner wrench tighten the adjusting nut. Return the speed selection lever to the neutral position. Measure the rolling torque and repeat until 10 in -lb. of rolling torque is achieved. Tighten the three setscrews to retain the adjustment.

6.1.28 Aligning Tailstock to Spindle (see Figure 6-8)

If there is taper appearing on the workpiece while machining by using the tailstock, the tailstock will need to be realigned to the spindle. Follow these steps:

1. Insert a gage bar between the spindle and tailstock, attach a base of a dial indicator to the saddle, apply the needle of the indicator to the surface of the bar, then move the saddle through the longitudinal travel. Take the measurement of its maximum difference from end to end for later adjustment.

2. Release the 4 bolts labeled “A” in the drawing.

3. Release the screw labeled “B”.

4. Adjust screw “C” until the tailstock is aligned with the spindle.

5. Tighten up the locking nuts “A” and screw “B”.

6.1.29 Spindle Motor Wiring (also see section 2.12)

The 1440 & 1745 spindle motors are wired for 220 volts (low voltage) in the configuration. The wiring consists of 3-phase power for the motor and 110 V power for the spindle motor fan. Please see Figure 6-9 for the wiring of each motor.

Each machine does however use a different spindle motor and pulley combination.

Each junction box contains 6 terminals. The terminals should be jumpered together as shown in the figure. Connect the incoming 3-phase power to the terminals as shown below. Make sure to hook up the wires in the same terminals after the replacement motor is installed. Failure to do so may run the motor in the wrong direction.

The spindle motor fan wires are also found in the junction box. There is 1 hot wire, 1 neutral wire and 1 ground wire. The hot and neutral wires are connected as shown for each motor. It does not matter which wires are connected to the hot and neutral wires.

All grounds from each cable are connected to either of the screws labeled ground.

6.2.1 Gib Adjustments

The objective of adjusting the gibs is to eliminate as much play in the table, saddle sliding surfaces as possible without having the tightness of the gib interfere with their free movement and cause a decrease in the accuracy and/or performance of the machine due to excessive friction.

6.2.1.1 Cross Slide Gib Adjustment

1. Take out yoke screws on top of cross slide.

2. Tighten gib screw and move cross slide back and forth. It should feel somewhat tight, but not to the point where it is hard to move.

3. Mount a dial indicator on the carriage and measure the slop in the cross slide. The dial indicator should be mounted a few inches in front of the tool post. (Note: this should be where the gibs are worn the worst.)

4. Try to move the cross slide back and forth to measure the amount of play. The dial indicator should only move between a 0.0002" and a 0.0005". If it moves more than this then tighten the gibs.

5. Turn the X-axis ball screw with a torque wrench and measure the torque. The torque should be less than 15 in/lb. and consistent over the travel of the X-axis. If the measurement is higher than this then loosen the gib. Make sure the cross slide is aligned properly. One easy way to check for this is to remove the yoke bolts and see if the yoke springs back into position. Misalignment is also evident if the torque is higher when the yoke is up against the rear bearing housing.

6.2.2 Calibration & Backlash Constants

Calibration and backlash constants were set as part of the installation and set-up of your system. They should be re-set when indicated in the Troubleshooting section or after the replacement of the computer module, or any parts of the drive train.

Calibration is used teach the machine a known distance. We typically calibrate our machines over a 150 mm distance. There is no limit to how far you can calibrate the machine.

6.2.2.1 Calibration

NOTE: Calibration usually is only done after replacing a computer module or adjusting the drive train.

1. Recheck machine level and adjust as necessary.

2. Press the “SERV CODE” soft key.

3. Input 123 on the keyboard, then press the “INC SET” key.

4. Input the “X” key to tell the control the x-axis is being calibrated.

5. Place the .0001 indicator in the spindle and set up the metric standard on the cross slide. Make sure the standard is parallel to the cross slide by using a combination square. Ensure that the standard is set up so that the readings will be taken with the cross slide extended towards the operator and moving in towards the motor end of the x-axis.

6. When the indicator is zeroed at the beginning of the standard press the “INC SET” key.

7. Move the cross slide towards the motor side of the x-axis until the indicator zeros on the end of the 150mm standard. Input 300mm when control prompts for a standard length.

8. If the calibration was successful the screen will return to the set up screen.

9. Press the “SERV CODE” soft key.

10. Input 123 on the keyboard, then press the “INC SET” key.

11. Press the “Z” key to tell the control that the Z-axis is being calibrated.

12. Set up the metric standard on the Z-axis ways.

13. Set up the magnetic base and .0001 indicator on the cross slide.

14. When the indicator is zeroed at the beginning of the standard press the “INC SET” key.

15. Move the saddle towards the chuck until the indicator zeros on the end of the standard, then press the “INC SET” key.

16. Input 150 on the keyboard.

If the calibration is successful the screen will change to the set up screen.

6.2.2.2 Backlash Compensation

Code 127: Calculate X or Z Backlash Constant

Every mechanical system has at least a little backlash or lost motion. It is produced by the small amount of play between the gibs and ways, and mostly by the accumulative bending or elasticity of all the parts of the drive train under load. The backlash constant is factory set, but may need to be adjusted periodically.

1. Set a .0001 inch dial indicator in the spindle, and touch off on a block or the vise along the direction (X or Z) you wish to check, or set the backlash constant.

2. Turn on the ProtoTRAK and at the Main Menu, follow the procedure below precisely:

The following is an example of what you might see when running this code. c. Press SERV CODES d. Press “B” e. Press X or Z f. What is shown is the current value.

Follow the instruction on the screen

and press the appropriate soft keys.

Wait a few seconds between each

INCR VALUE or DECR VALUE

press.

For example, if the up and down "Oscillation

Value" shown in the conversation line is .00278 inch, and the dial indicator is moving back and forth .0012, then the true backlash value is

.00278 -.0012 = .00158 inch. Input this by pressing MODE, SET UP, SERV CODE, 128, SET and then .00158, SET, RETURN.

3. The X backlash identified and stored in Step 2 should be less than 0.003” on a new machine. If it is appreciably larger, inspect the drive train for loose bolts, brackets, bearings, etc.

The backlash can also be found manually with a 0.0001” indicator with the following method.

• Load the indicator to zero from one direction and zero out the DRO.

• Move the indicator to 0.002” and then back to zero. Do not over shoot 0, otherwise start over.

• Whatever number appears on the screen is the backlash value.

• Enter this value into service code 128.

• After entering this number redo the process. The DRO and indicator should now both read 0.

CODE 128: Input Backlash Constant

Code 128 allows you to enter the backlash values for each axis. It displays the value after it is entered.

Be sure not to enter too much backlash on any given axis. Too much backlash in the system may cause bi-directional repeatability problems or axis motor searching.

6.2.3 Lubrication

An oil pump provides lubrication for an even distribution of oil to all the gears and bearings in the headstock. One of the oil lines pumps oil to a site glass located on the headstock. Periodically check to see that oil is flowing.

The plug to drain the headstock is located under the spindle cover towards the bottom of the casting. See Figure 6-12. Oil can be added to the reservoir by a plug in the top of the headstock cover or by removing the cover and pouring it into the headstock. There is a level

site glass located under the spindle cover. The headstock reservoir holds approximately 3 1/2 gallons. Fill the headstock with Mobil DTE 24 oil or an equivalent grade.

The headstock gearbox oil must be drained and flushed after the first 150 hours of operation. A small percentage of kerosene may be added to the gearbox to flush out dirt and sediment. Operate the machine for several minutes without load so that the flushing oil can circulate through the reservoir and remove the dirt. The flushing oil must then be drained and new oil added. Do not flush with solvents that will soften the paint.

Thereafter, the oil should be flushed and drained every 1500-2000 hours of operation.

TRAK Warranty Policy

Warranty

TRAK products are warranted to the original purchaser to be free from defects in work-manship and materials for the following periods:

Product

Warranty Period

New TRAK

Any EXCHANGE Unit

Materials

1 Year

90 Days

Factory Labor

1 Year

90 Days

The warranty period starts on the date of the invoice to the original purchaser from Southwestern Industries,

Inc. (SWI) or their authorized distributor.

If a unit under warranty fails, it will be repaired or exchanged at our option for a properly functioning unit in similar or better condition. Such repairs or exchanges will be made FOB Factory/Los Angeles or the location of our nearest factory representative or authorized distributor.

Disclaimers of Warranties

• This warranty is expressly in lieu of any other warranties, express or implied, including any implied warranty of merchantability or fitness for a particular purpose, and of any other obligations or liability on the part of SWI (or any producing entity, if different).

• Warranty repairs/exchanges do not cover incidental costs such as installation, labor, freight, etc.

• SWI is not responsible for consequential damages from use or misuse of any of its products.

• TRAK products are precision mechanical/electromechanical measurement systems and must be given the reasonable care that these types of instruments require:

• Replacement of chip scrapers and wipers is the responsibility of the customer. Consequently, the warranty does not apply if chips have been allowed to enter the mechanism.

• Accidental damage, beyond the control of SWI, is not covered by the warranty. Thus, the warranty does not apply if an instrument has been abused, dropped, hit, disassembled or opened.

• Improper installation by or at the direction of the customer in such a way that the product consequently fails, is considered to be beyond the control of the manufacturer and outside the scope of the warranty.
