FOUNDATION, LEVELLING AND ANCHORING

Machine location should be carefully selected. A flat concrete floor area should be chosen. It should haveenough free space surrounding the machine to enable free access for safe operation and maintenance.

Machine should be levelled in both directions ie. along and across its infeed conveyor specially when machine isto be inserted into a larger conveyor system.

Five levelling screws are provided, one in each corner of the machine base. Steel plates are to be placed undereach screw to prevent their sinking into the concrete floor. In cases where the machine is to be anchoredpermanently, anchoring holes are provided. They are located next to the levelling screws.

NOTE: In some cases levelling the saw infeed and auxiliary conveyor with a slight slope towards blade isrecommended.This will prevent coolant from running down the raw stock. (This is especially true whencutting tubing or bundles).

Use a precision level in bothdirections on the infeed conveyor.

Pg 1.4 H2832

HYDRAULIC OIL AND CUTTING FLUID

The H-28, H-32 bandsaw is supplied with Arco Duro 46 hydraulic oil. If it is necessary to change the oil to adifferent brand see the HYDRAULIC SECTION for an equivalent grade oil.

No cutting fluid is supplied with the machine. There are two types of coolant available:- oil based; dilute 1:10 ratio (one part concentrated coolant to 10 parts water)- synthetic; dilute as recommended by the manufacturer.

WIRING CONNECTIONS

After the machine is levelled and anchored the necessary power hook-up needs to be performed. In order toprovide safe operation as well as to prevent potential damage to the machine, only qualified personnel should makethe connections.

BEFORE START-UP THE FOLLOWING TWO POINTS SHOULD BE CHECKED;

- signs of damage that may have occurred during shipping to the electrical cables and the hydraulic hoses.- the hydraulic oil level is between the upper and lower lines on the level gauge.

As supplied, the machine is set to run on three phase voltage as indicated on the serial plate and voltage label.Power connection to the machine is made to L1, L2, L3 and Ground terminals in the main disconnect box. Formachines equipped with a variable frequency drive unit, an earth ground is also recomended.

During the initial hook-up it is very important to check that the phase order is correct. This is indicated by thehydraulic pressure gauge registering a pressure rise and the blade running in a counter clockwise direction. If thehydraulics do not register an immediate pressure rise, shut the hydraulics off and change the phase order.

ATTENTION: Running the hydraulics "backwards" can damage the hydraulic pump.

SECTION 3, MAINTENANCE AND TROUBLE SHOOTING

LOCK -OUT

Purpose: To prevent injury to workers caused by unexpected start-up of machines beingworked on.ORWhere the starting of a machine or device may endanger the safety of a worker

a) Control switches or other control mechanisms shall be locked out;ANDb) Other effective precautions necessary to prevent such starting shall be taken

LOCK OUT PROCEDURE

Whenever work is to be performed on a machine, the person in charge should follow Lockout procedures as isrequired by his organization. The main power disconnect box is supplied with a suitable mechanism for thispurpose as shown below.

Switch shown in the OFF position.

Pg 3.2 H28

BLADE BRUSH ADJUSTMENT

The blade brush is properly set when machine leaves the factory, but it wears outduring operation and needs to be readjusted periodically. The blade brush assemblyis found behind the drive side door and is shown below. To adjust the assembly,loosen the hex nut, turn the set screw counterclockwise until the wires on the brushtouch the bottom of the blade gullets and tighten the hex nut.

The brush should be replaced as it becomes worn to approximately 70% of it'soriginal 3" diameter. Replacements can be purchased through your Hyd-Mech Dealer.

BLADE CHANGING PROCEDURENOTE: Wear gloves, safety glasses and a long sleeve shirt for protection from the sharp blade.

The hydraulics should be OFF any time the operator has his/her hands in contact withthe blade.

1. Select MANUAL mode and raise the head so the drive door will clear the electrical control panel.

2. Release the blade tension by turning the Blade Tension Switch to "-".

3. Remove the blade guard.

4. Shut the machine off and open the idler and drive doors.

5. Loosen the carbide locking levers by turning counter clockwise 1/4 turn.

6. At the top of the head, the saw blade runs in a protective channel. Grip the blade at each end of thischannel and twist the blade teeth down past the channel and slide the blade forward. Let the blade rest on theout feed table, then slide the blade down and out of the carbide guides.

7. Before installing the new blade, check that it measures 1.615" wide including the teeth. Some blademanufacturers supply blades that measure 1.5" including the teeth. The same applies to 2" blades, they shouldmeasure 2.120". In this case you may not be able to adjust the head down limit to complete the cut.

8. Your new blade will be in a coil. While wearing gloves, hold the blade away from yourself, twist the blade touncoil it. Do not let the blade teeth bounce on the concrete floor as some damage to the blade may be caused.

9. Place the new blade in the carbide guides and then slide the blade over the wheels. The teeth should bepointing towards the drive side as they pass through the carbide guides.

10. Turn the machine on and the blade tension switch to the "+ RUN" position, turn the two carbide lockinghandles clockwise to the locked position. Jog the blade a few rotations to check that the blade is not movingon or off the wheels.

BLADE TRACKING

Blade tracking is set so the teeth of the blade protrude .260" (6.6mm) for an H-18 and for anH-22, .310" (7.9mm), +/- .01" (.25mm) from the face of the idler and drive wheels. Adjustments should always

begin with the wheel that measures farthest out of specification.

IDLER WHEEL TRACKING

Release blade tension before adjusting. Adjusttracking by regulating "push" set screws and "pull"bolts. Loosening bolts "A" and turning in setscrews"C" by equal amounts will move the blade OFF thewheel. Loosening bolts "B" and turning in sets crews"D" by equal amounts will move the blade ON to thewheel. After each "C" or "D" set screw adjustment,tighten bolts "A" or "B", turn tension switch to "+RUN",run the blade for a moment and recheck the tracking.

DRIVE WHEEL TRACKING

Release blade tension before adjusting. Loosensupport hex nuts & set screws"A". On bolts "B", there isa jam nut between the gear box and mounting plate,loosen this jam nut. Turning bolts "B" out by equalamounts 1/4 turn at a time and tightening set screws "C"will push the blade OFF the wheel. Loosening set screws"C" and tightening bots "B" will pull the blade ON thewheel. Sug up bolts "A", turn tension switch to "+RUN",run the blade for a moment and check the tracking. Whenadjustment is completed, tighten the jam nuts on bolts"B", support set screws "A" & jam nuts.

There is an identical set of "B" & "C" screws,etc. on the wheel side of the gear box. These may beused when the set shown will not set tracking as desired.This set may be accessed through the drive wheel wall. Itmay be necessary to turn the drive wheel.

CAM FOLLOWER ADJUSTMENT

There are two cam followers mounted on the head frame. The set of cam followers isshown in the photo. One of them is fixed and the other is adjustable. The cam followers arefactory set and usually do not require adjustment. In a properly adjusted system of camfollowers only one side should be in contact with the guide. The gap between the other andthe guide bar should not exceed 0.001". If it exceeds 0.001" you should contact your dealerto arrange for adjustment.

Pg 3.4 H28

LUBRICATION

The design of the H-28 and H-32 were intended to minimize maintenance, although periodically certain movingparts need lubrication. We recommend that this periodic lubrication be done once a month using any generalpurpose grease. In addition to the grease points shown, vise jaw guides, infeed rollers and bundling assembliesrequire greasing.

Pg 3.5 H28

HYDRAULIC MAINTENANCE

There are only FIVE items of routine maintenance associated with the hydraulic system.

1. OIL FILTER - Ten micron filtration of the hydraulic oil is provided by a spin on type filter mounted on thetank return line. The element should be changed after the first 50 Hours of operation and then every 500 workinghours. Suitable replacement elements are:

CANFLO RSE-30-10GRESEN K-22001PARKER 921999

ZINGA AE-10

2. OIL LEVEL - Oil level should be maintained in the upper half of the level gauge. Normally the rate of oilconsumption will be very low and it should be unnecessary to add oil more often than at filter changes. Add oilonly to the top line on level gauge.

The machine is shipped from the factory with ARCO Duro AW46 hydraulic oil. Generally any brand ofrecognized mineral hydraulic oil with the same properties should be compatible with Duro AW46, but to avoidany risk we suggest staying with Duro AW46. If it is desired to change brands, it is necessary to drain the tankand 1/3 refill it with the new oil, operate through several full strokes of each cylinder, drain the tank again, andfinally fill the tank with the new brand.

Hydraulic tank capacity is approximately 11 US gallons (42 L).

Recommended replacement oils:Chevron, AW Hydraulic Oil 46

Esso, NUTO H46Mobil, Mobil DTE 25Texaco, Rando HD 46

Shell, Tellus 46

3. OIL TEMPERATURE - Oil temperature is indicated by a thermometer contained in the level gauge. Oiltemperature during steady operation should stabilize at about 50 - 55 F° (10-12°C) above room temperature.Thus in a 70 F° (20°C) shop one might expect an oil temperature of about 120 F° (50°C) Oil temperature shouldnever exceed 160 F° (70°C)

4. OIL PRESSURE - Oil pressure is factory set to 950 PSI (6548 kPa ) for H-18 and should not requirefurther attention except precautionary observation at start-up and every few days thereafter.

5. BLADE TENSION - Is preset at the factory and should under normal conditions not require attention. Foradjustments, see the hydraulic schematic.

CLEANLINESS

The heavy duty design should endure heavy operating conditions and provide the customer with flawlessmachine performance. To extend good performance some care is required especially as cleanliness is concerned.

The following areas should be kept clean:- Control console free of dirt and grease.- Door charts free of dirt and grease.- Wheel boxes free of chips.- Blade guides free of chips.- Outfeed table free of chips.- A large chip build-up should be avoided in the base of the saw.

NOTE: All parts must be cleaned before any repair service can be performed on them.

PROGRAMMABLE LOGIC CONTROL, MITSUBISHI 100

NOTE: The PLC is equipped with a lithium battery to keep the program stored while the power is shut down.The battery will need to be replaced every 3 to 5 years, depending on usage. A visual warning will be displayed onthe interface when the battery drains to a certain level. Battaries can be purchased through your Hyd-MechDistibutor.

The programmable length control (PLC) uses signals from limit switches, control panel switches, an encoder(rotary shaft or linear) and information which is programmed into it, to supply accurate automatic length control andsawing functions.

The inputs used include;- a head up limit switch, a head down limit switch;- the machine function switches & push-button- also a signal from the auto/manual push button (telling the PLC whether auto or manual operation has been chosen).

An encoder is attached to the shuttle assembly and travels with the shuttle to provide length information to thePLC. A proximity switch and target, mounted to the gearbox drive pulley or behind idler wheel, provides bladespeed input to the PLC.

The programmed information includes logic put into the PLC be its manufacturer, as well as informationprogrammed in, through the keypad, by the assembly plant. Information from the assembly plant is referred to asthe parameters. The parameters are important for the PLC to provide accurate sawing lengths and blade speeddisplay. Following is a description of each parameter and the procedure to access them.

To view the PLC parameters:

For semiautomatic "P" models, refer to the PLC key description of in Section 2A.

For automatic models;

In manual mode, with front vise switch in 'CLOSE' position press FWD. and REV buttons simultaneously ( notmore than 0.5 sec. apart). The PLC will prompt for a password which is obtainable from Hyd-Mech Saws. If thepassword is correct a screen of parameters will appear. The display will show two lines of parameters at a time.The first display is for the machine's self calibration of it's length control. If the length control calibration isnecessary, follow the calibration procedure on page 3.20. To move through the parameters use the cursor keys toscroll up or down. To change a parameter, cursor to that parameter line, and, using the number keys, type in thenew value and press enter. To leave the parameters press the Auto/Man key. The following page lists the availableparameters and their definition.

Pg 3.9 H28

PLC 100 PARAMETERS

Parameter Definition

HGT CLB "ENTER" This is to be used only if calibration is required. Call Hyd-Mech Service department forinstruction.

ACT HT - Actual Height Value. Value that must be entered after performing Head Height Calibrationprocedure (see Pg. 3.18). This value represents the head full stroke height. (Thisparameter is not present on machines which have a head up and down limit switch. S-20A,H-10A and some early M-16/20A)

FST APR DIST - Specified distance the head will move up above the preset material height. When theAUTO cycle reaches the function of head down, the head will fast approach the distanceminus the FAST APPROACH OFFSET parameter. (Next parameter; FST APR OFST)

FST APR OFST - Specified distance above the preset material height that the fast approach fuction willshut off. (I.E. If set for .250, the fast approach will shut off and normal feed will begin at.250" above the preset material height).

DOWN DWL - Sampling time when head reaches down limit. In AUTO, head will not move up afterreaching down limit until this delay time has elapsed.(1 = .01 seconds, Range = 300 - 999)

LTH CLB "ENTER" This is to be used only if calibration is required. Call Hyd-Mech Service department forinstruction.

ACT LTH - Actual Length Value - Value entered after performing length calibration procedure (See Pg.3.17). PLC uses this value to calculate it's length encoder resolution and stroke parameter.Note: If Calibration Procedure is activated and not completed, or activated and a value notentered for ACT LTH, this value will reset to 00.000 and the PLC will not be able to count/display lengths.

STROKE - Total length, in inches, the shuttle will travel in a single stroke.(Calculated & Entered by the PLC; cannot be changed by operator)

ACC DIST - Distance, in inches, the shuttle will travel slowly before reaching fast speed while startingto move in either direction. (i.e. 1.000).

DEC DIST - Distance, in inches, the shuttle will travel slowly reaching home or target position. \(i.e. 1.000)

SLW DIST - Minimum fast speed distance, if programmed length is smaller than this parameteroverride to slow speed. (Shuttle)

TRG WD - Allowable +/- tolerance from programmed length.FVO DEL - Delay time for the opening of the fixed VISE. A value of 100 is approximately equal to

about one second. (i.e. 75=.750 seconds delay)SVO DEL - Delay time for the opening of the shuttle VISE. (i.e. 75 =.750)CLS TIME - Delay time for closing front or shuttle VISE. (i.e. 75 =.750)SPD FCTR - Blade speed adjustment number. If Actual Blade speed is different than displayed Blade

Speed a new speed factor will need to be calculated. (Providing wheel Trgs is set correctly):Actual speed / Display = adjustment factor Adjustment factor XExisting speed factor = New speed factor

WHEEL TRG - Number of targets per revolution of the idler wheel. S-20A, S-23A, H-10, M-16/20 = 1H-18/22, H-28/32 = 6

ACT POS - If this value is set to 1 displays actual position.HLD SHM HM - Hold shuttle VISE home and closed during cut.BRKN PROX - Allows user to override signal from prox switch in case it is broken. (When set to value -

0; machine will not run with broken proximity sender. Set to value - 1; allows machine toRun).

BLDE CHAM - If this parameter is set to '1' ; When the AUTO cycle reaches the function of head up, theshuttle will retract the material from the blade by 1/8" before the head will move up. Whenthe head reaches the up position the next length of material is shuttled into position.

PLC 100 TROUBLESHOOTING

PROBLEM #1, for automatic models with a shuttle.

PLC is not measuring lengths.

POSSIBLE CAUSES;i) Encoder - pinion gear loose on encoder shaft

- bad encoderii) Encoder Cable - bad connection at encoder or PLC

- open or shorted wireii) PLC unit - damaged hardwareiii) Display unit - no power from PLC unit

- damaged hardwareiv) Actual Length (ACT LTH) - preform self calibration procedure and enter value.

Parameter value is set to 00.000

DIAGNOSIS;I) With the machine in MANUAL mode; bring the shuttle forward to the home position and clear thelength display to read '0.000'. Run the shuttle, in slow speed, to the rear then back to home, moving fullshuttle strokes.- length should accumulate on the display as a positive number when the shuttle moves away from theblade and should count is negative going back and goes in a positive direction coming toward home,then the green channel wire and the white channel wire should be reversed.- if the display alters between 0.000 and 0.001 or 0.000 and -0.001, then one of the encoder channelsis not being recorded correctly.ii) To determine the cause, first, check the encoder cable connections at both ends to be sure all fourwires are connected properly. (See page 3.16 for connection / wiring information).

Measure the voltage:a) At encoder connector;

- between 0 V pin and 24 V pin. This voltage should be a minimum of 22 to 26 VDC.

If the voltage is incorrect; check encoder cable continuity - if OK, possible PLC problem.If the voltage is correct, go to step b)

b) At encoder connector;- between 0 V and channel A and 0V and channel B. This should be slightly less than supplyvoltage at each channel.If voltage is incorrect at this point, check for proper continuity of these wires and repair asnecessary.

NOTE: When checking the encoder cable for continuity, each wire should also be checked forshorting to ground and shorting to each other.If voltage to the encoder is correct; go to Step C).

c) At the encoder connection of the PLC; - between 0 V and A&B channels. With the shuttle movingslow, voltage should be approximately 10 -13 VDC. Input LED's X0 and X1 should flicker or go dimwith the shuttle moving. If these LED's show no change with the shuttle moving, the encoder islikely at fault. Check that the pinion gear is securely fastened to the encoder shaft and that it canrotate along the rack as the shuttle moves.If all mechanical components are functioning correctly then the encoder is defective.If all tests check positive, the problem is in the PLC unit.

Pg 3.11 H28

PROBLEM # 2, for automatic models with a shuttle.

Inaccurate lengths in AUTO mode.

POSSIBLE CAUSES;i) Encoder - pinion not engaging rack all the way from front to back;

mechanical interference, pinion loose on encoder shaftii) Encoder Cable - bad connection at encoder or at PLC

- intermittent open in one or more signal wiresiii) Improper programmed information

- existing parameter(s) incorrect- incorrect blade kerf

iv) PLC - faulty PLC unit (not repairable in the field)

GENERAL RULES - Normally, three types of length inaccuracies may occur.

1) Inconsistent - lengths cut are not consistent, error changes. It doesn't matter how long the partrequired is the error is never the same.

Cause: - most likely a defective electrical, hydraulic or mechanical component.

2) Consistent - lengths cut are consistent and the error is also consistent. The error always stays thesame regardless of part length.

Cause: - Kerf value

3) Linear - lengths cut are consistent but the error increases as the part length increases. Thelonger the part the greater the error.

Cause: - when self-calibration is executed, incorrect "Act Lth" value entered

DIAGNOSIS;i) Check and record existing parameters. Also check for proper blade kerf. By making a cut part way into apiece of material and measuring the width of the cut, the operator can check blade kerf.

INCONSISTENT INACCURACY;ii) - with the machine in MANUAL mode, move the shuttle all the way forward and clear (zero) the lengthdisplay. Move the shuttle in reverse, in slow speed, all the way to the end of it's travel.Return the shuttle forward to the home position, also in slow. The display should read 0.000" +/- .005". Do thistest several times to be sure the read-out is repeatable.

DIAGNOSIS;iii) Following the same procedure, run the shuttle alternating between fast and slow speed going back andcoming forward. Again the display should be able to read 0.000" +/-.005" when returning to the home position.If the display does not read as specified:

- check the encoder pinion gear to be sure it can run smoothly down the rack and that the gear and rackteeth engage over the entire travel of the shuttle.- check that the pinion gear is tight on the encoder shaft.- check the encoder cable connections, a loose connection could easily cause this concern.- remove the encoder from the machine and check that the shaft can rotate freely. There should be nobinding or rough spots felt when spinning the shaft. Plug the encoder cable into the encoder, clear thelength display, and rotate the shaft exactly (or as close as possible) one revolution. The display shouldread approximately 3.142" (positive or negative). Repeat this 3 or 4 times, spinning the shaft severaltimes between tries.

Pg 3.12 H28

CONSISTENT INACCURACY: (make sure blade kerf value is correct)- change "Actual Pos." parameter to 1.This will make the PLC show actual shuttle travel in AUTO

With no material in the machine:- program JOB 1 for 2 pieces of 5" length, JOB 2 for 2 pieces of 10" length, and JOB 3 for 2 piecesof a length as one shuttle will allow.- enter JOBS 1, 2 and 3 into QUEUE.- record measurement on the display each time the shuttle vise reaches the target length andcloses. It should equal the required length plus the programmed kerf value. Check that thismeasurement is +/-.002" for each length.If the overshoot /undershoot is very inconsistent, it could be related to an incorrect shuttle cushionperiod. This may be caused by "Decel. Dist." parameter being set too low, defective fast or reverseoutput relays on the PLC, or the hydraulic cushion valve (located at the hydraulic manifold) may befaulty.

LINEAR INACCURACY: (not valid for machines with linear encoder)v) - load machine with a piece of stock for test cutting

- open parameters screen- initiate length calibration (see 3.17)- re-enter new ACT LTH (Actual Length) value- recut test lengths and check if accuracy is satisfactory.

Pg 3.13 H28

PROBLEM # 3, for P models, disregard all references to a shuttle.

AUTO cycle not being completed.

In the AUTO mode, the PLC controls saw functions through output relays. For a certain function to beactuated, the PLC must first see specific input(s). Like the output relays, the input relays are located on thePLC unit. Directly beside input and output terminals are red LED lights, which light up when the correspondinginput is being received or output is being actuated. Observation of these input/output LEDs can help to diagnoseAUTO cycle problems. (See PLC UNIT drawing on page 3.15) When a problem occurs in the AUTO mode, thelights should be checked to see if they are coming on at the proper time or at all.

INPUT LED's - If a specific input light does not come on when expected;- check for a faulty/misadjusted limit switch, push button, encoder or by faulty wiring orpoor connections.- wiring for each limit switch should be connected from the VDC terminal connection toparticular limit switch, and from the limit switch to the input connector of the PLC.

NOTE: All inputs are denoted by "X"All outputs are denoted by "Y"

Following is information on output diagnosis and the sequence of inputs and outputs during AUTO cycle.

AUTO CYCLE SEQUENCE: After the mode push button is in the AUTO position and the job has beenProgrammed into the PLC, and the Cycle Start push button pressed:

1) Hydraulics running, the head should move to it's up limit, if it is not already there. Shuttle vise should openand come forward to the home position.

HUP input light must come on for cycle to continue.HUP input on - cycle should continue, if not check outputs per step 2.HUP input not on - check that head up limit switch is being actuated, check limit switch / limit

switch wiring.2) Front vise should be closed, the shuttle vise should stay open and move back to the programmed length;FVC output should be on and SVO output will light momentarily, REV output and FST output should be onwhen the shuttle moves back fast.3) As the shuttle approaches target length the FST output should shut off and the shuttle should travel slowfor the "Dec. Dist." parameter, cushion distance. (i.e. 1.00") When the shuttle reaches target length, the SVCoutput should light, and the shuttle vise should close on the material.4) FVO output light should come monetarily on and front vise should open.5) FWD output should light as will as FST for the shuttle to move forward in fast speed. FST will turn offwhen the shuttle home cushion period is reached and the shuttle should slow down into thehome position.6) FVC output should light and the front vise should close. FWD light should go out, HDN output shouldcome on and the head should start to descend for the cut. If blade is not running at this time, auto cycle willhold until min. SFM is reached. Depending on "Hld Shtl Hm" parameter in the PLC, the shuttle may stay homeand closed during the cut or may move back to pick up the next length. HUP input should go out as the headdescends, and HUP L/S deactivates.7) After the cut is completed HDN input should light, HDN output should go out, the HUP output should lightand the head should move up. When the head reaches it's up limit, HUP input should come on, RHD outputoff and the cycle repeats with the next length being clamped on by the shuttle, front vise opening and thelength being brought forward to home position.

Pg 3.14 H28

As mentioned, beside each input and output terminal there is a bank of red LEDs. Each light corresponds toits input or output. An input LED will light when it's specific input signal is being received at the PLC and outputLED's will light when the PLC commands specific outputs. If an output LED is on but the output does not happen,check for voltage at the specific output wire. If voltage is not present then either the output relay is faulty/stuckor the output (3 amp) fuse has blown. (See fuse information below) If a fuse is blown, a shorted directionalvalve coil (good coil should measure 30 to 40 ohms), shorted noise suppresser at the coil, or shorted wiringcould be the cause.

If the fuse is good and no output voltage condition still exists, with the output light on, then the relay isdefective.

If this is the case the PLC will have to be returned to the manufacturer for repair. (Contact HYD-MECH SAWS).

FUSES: The PLC has five glass fuses in line with it.

Fuse 'F1' is a 2 amp instant blow fuse which feeds power to the input side of the PLC through inputterminal 'L'.

Fuses 'F2' to 'F5' are 3 amp time delay fuses which each supply power to a specific bank of output relaysthrough that bank of relay's 'COM' terminal:

F2 is wired to terminal 'COM 1' supplying Outputs - Y0, Y1, Y2, Y3F3 to terminal 'COM 2' supplying Outputs - Y4, Y5, Y6, Y7F4 to terminal 'COM 3' supplying Outputs - Y10, Y11, Y12, Y14F5 to terminal 'COM 4' supplying Outputs - Y14, Y15, Y16, Y17

PROBLEM # 4, No Display.

POSSIBLE CAUSES;i) No power to the PLC.ii) PLC unit failure.iii) Faulty connection of cable between PLC & Interface

DIAGNOSIS;i) Check POWER LED (see page 3.15 - Status lights) - to be on when the PLC is switched on.

If the light is on, PLC may have failed. Check for proper connection of cable at PLC & at interface.If connection is secure replace. If light is not on - check the (2 amp) PLC fuse.If the fuse is OK, check power to it.

PROBLEM # 5, No Blade Speed Display.

POSSIBLE CAUSES;i) Fault at proximity sender - bad sender, misadjusted sender (gap should be approx. 0.015")

- contamination on the end of the senderii) Fault at the PLC - bad connection of sender wiring

- faulty PLC input

DIAGNOSIS;i) Check for LED light on the sender - light on indicates prox. sender power connections are correct and

sender is activated. Problem could be with the sender, signal wire to the PLC or with the PLC. With bladerunning, proximity LED should pulse. Likewise, the PLC input LED (X2) should be pulsing. If both LED's arepulsing with the blade running, the PLC is the problem. If the sender LED is pulsing but the input (X2) LED is not;there is a problem between the sender and the PLC input (X2) terminal.

- If the LED on the sender is not on, the problem is with the sender wiring or the sender is at fault.

CALIBRATION PROCEDURE FOR MITSUBISHI PLC100E NOT APPLICABLE TO "P" MODELS WITH 50E SOFTWARE

In manual mode position a piece of material which is longer than the shuttle full stroke length (i.e. M-16A =32.500") and close the front VISE. Simultaneously depress "FWD" & "REV" buttons on the PLC to accessparameters. A password is required at this point which can be obtained from Hyd-Mech Service Department.

SCREEN WILL DISPLAY:

With the cursor @ shown position (as illustrated above) press enter. The cycle start button will then start to flash& "0" will change to "1" indication self-calibration mode. Start the blade and the trim cut will be made. After the trimcut is made the head will rise, the shuttle will retract fully in slow, clamp the material and come fully forward in slowto the home position and make a cut. After the cut is complete "1" will change back to "0". Measure the cut partlength.

Cursor down to ACT.LTH. and enter length of cut part plus the actual kerf value. Then exit the parameters bytoggling the AUTO/MAN button (the cycle start button will stop flashing). The ENC.RES. & full stroke values will nowautomatically be calculated and programmed by the PLC.

*NOTE: When first entering the parameters screen if not running the self calibration do not use the enterkey but use the cursor keys to scroll through the parameters.

To check length control consistency:

1) Perform test cuts of three different lengths (i.e. 6", 12", 20") and measure as accurately as possible.

2) If the measurements indicate a linear problem (measured length error increases as the programmedlength increases), the ACTUAL LENGTH value will have to be adjusted.

3) The Length Calibration Procedure MUST be performed to allow a change to the ACTUAL LENGTHparameter. This may be done with material in the machine (cut and measure material length) or with nomaterial in the machine (let machine complete the calibration cycle, then enter new value).

To adjust ACTUAL LENGTH parameter:

- If part length error gets longer as the programmed length increases; ACTUAL LENGTH value should beincreased.

- If part length error gets shorter as the programmed length increases; ACTUAL LENGTH value should bedecreased.

- Make small adjustments at a time (i.e. .020" - .030") and recheck with test cuts.

EXAMPLE: If part length error gets longer as programmed length increases:Existing ACT.LTH.=33.070"Change ACT.LTH. to 33.070 + .020 = 33.050"

LTH.CLB. "ENTER" 0

ACT.LTH. 00.000

Pg 3.18 H28

HEAD HEIGHT CALIBRATION

1) Enter the PLC parameter screen as per Length Calibration Procedure on the previous page.

2) Using the arrow cursor keys scroll down until the screen displays :

HT CLB "ENTER" 0

ACT HT 00.000

3) With the cursor on the 0 , press the ENTER key. The cycle start button will begin to flash, the headwill move to it's down limit and then will move up to it's full upper limit.

4) Measure the distance from the vise horizontal wear strip to the blade teeth tips, and enter this value in theACT HT parameter. Measurement must be made along the front vise datum jaw. Input this measurementvalue & press the ENTER key. Press the AUTO/MAN key to finish the procedure & exit the parameters screen.

SECTION 4, ELECTRICAL SYSTEM

GENERAL INFORMATION

This machine has been built to the customers requirements, however, if any voltage changes are required,consult Hyd-Mech service department before implementing any changes.

INITIAL HOOKUP

At initial hook-up it is important to check that the phase order is correct. This is indicated by the blade drivewheel revolving in a counter clockwise direction and the hydraulic pressure gauge registering a pressure rise. On thefollowing pages are the electrical schematics and physical wiring diagrams along with a list and photos of electricalcomponents.

NOTES:1)The PLC is equipped with a lithium battery to keep the program stored while the power is shut down. Thebattery will need to be replaced every 3 to 5 years, depending on usage. A visual warning will be displayed on theinterface when the battery drains to a certain level. Battaries can be purchased through your Hyd-MechDistibutor.2) If the machine is equiped with an inverter, do not turn disconnect on for 3 three minutes after disconnect hasbeen shut off. Cycling power sooner than 3 minutes will result in damage to the Variable Frequency Drive.3) All of the machines equipped with a Mitsubushi PLC have a snap on Ferrite core on the interface cable. This isplaced near the interface in order to reduce "noise".
