TION,, LEVELLING AND ANCHORING
Machine location should be carefully selected. A flat concrete floor area should be chosen. It
should have enough free space surrounding the machine to enable free access for safe operation and
maintenance.
The machine should be levelled in both directions, i.e. along and across its infeed conveyor
especially when machine is to be inserted into a larger conveyor system. Four levelling screws are
provided, one in each corner of the machine base. Steel plates are to be placed under each screw to
prevent their sinking into the concrete floor. In cases when the machine is to be anchored permanently,
anchoring holes are provided. They are located next to the levelling screws.
NOTE: In some cases levelling the saw infeed and auxiliary conveyors with a slight slope towards the blade
is recommended. This will prevent coolant from running down the raw stock. (This is especially true
when cutting tubing or bundles).
2 leveling bolts at the idler side of the machine are shown.

Pg 1.3
WIRING CONNECTIONS
After the machine is levelled and anchored the necessary power hook-up needs to be performed.
In order to provide a safe operation as well as to prevent potential damage to the machine, only
qualified personnel should be allowed to do the work.
The first two areas that need to be checked are:
- There is no signs of shipping damage to electrical conduits, cords or hydraulic hoses.
- Hydraulic oil level is between the upper and lower lines on the level gauge.
During the initial hook-up it is very important to check that the phase order is correct. This is
indicated by the hydraulic pressure gauge registering a pressure rise and the blade running in a
counterclockwise direction. If the hydraulics do not register an immediate pressure rise,
- SHUT THE HYDRAULICS OFF and change the phase order. As supplied, the machine is set to run on the three phase voltage as
indicated on the serial plate and voltage label. Power connection to the machine is made to the main
disconnect switch and the Ll, L2, L3 and Ground terminals. The disconnect switch box is located on right
side of the Operator Control Panel. The Power Terminal Block is shown below. We also recommend
that an earth ground be attached to the machine.
To gain access to the disconnect box, follow these steps:
1) Ensure the switch is in the OFF position and power is diconnected.
2) Push the lockout tab to the right and pull the door open. In the case of a 240V machine,
the disconnect box will be smaller.
To close the door properly, reverse the above steps.

SECTION 2A, THE CONTROL CONSOLE
The M-16/M-20 control console has been designed to simplify the operation of the saw, to give the
operator the ability to stop any function at any time, and to be able to control all the functions remotely.
We can not overstress the importance of familiarizing yourself with the controls of the M-16 or M-20 prior
to starting the machine.
NOTE: 1) ALL SWITCHES MUST BE IN THE CENTER NEUTRAL POSITION TO START
THE MACHINE!
2) WHEN STARTING THE MACHINE FOR THE FIRST TIME MAKE SURE THAT
BLADE IS MOVING IN A COUNTERCLOCKWISE DIRECTION, AND THAT THE

In CLOSE, the vise will close all the way, or until it encounters enough
resistance to stop it. With the switch held in the OPEN position the vise
will open all the way or until the switch is released. With the switch in the
HOLD position, the vise will stay where it is and will not move freely
although it will not resist a large force indefinitely without creeping.
HEAD CONTROL - This switch has three positions: UP, HOLD and DOWN.
The switch is inactive unless the PLC is in manual mode. In the UP
position, the head will rise until it trips the head up limit which is
adjustable via the PLC. In the HOLD position the head will stay still. In the
DOWN position the head will descend until it reaches the bottom of the

OPERATION OVERVIEW
The PLC is a programmable length controller which allows the operator to run the machine in
both manual and automatic modes.
In manual mode, all functions can be operated by using a combination of selector switches on the
control console and the PLC function buttons. Also the operator has the ability to execute a single cut
utilizing a preprogrammed "Single Part Cycle".
In automatic mode, the PLC has the capacity to program and store 99 jobs. Designated job
numbers can be programmed for quantity required (maximum of 999 pieces) and lengths from 0" to
220" (5588mm).
Jobs can be run individually or in a QUEUE which allows a maximum of 5 jobs to run consecutively.
NOTE: If an emergency situation arises during any operations, use the large red
mushroom "emergency stop" button located on the control panel to shut down the
machine.

ASICS
BLADE
BASICS
Technology is rapidly changing all aspects of production machining. Metal cutoff is no exception.
The advances made in the bandsaw blade industry have definitely brought down the cost per cut, despite
the three fold higher price of high technology blades. Variable pitch, bi-metal blades (like the 4/6 or 3/4
bi-metal blade supplied with the M-16/20) last much longer, cut faster, and more accurately than conventional carbon steel blades. In order to take advantage of the superiority of bi-metal blades, it is critical to
properly “break-in” a new blade. This is accomplished by taking two or three cuts through solid four or
five inch diameter mild steel at an extremely slow feed rate. (It is also advisable to utilize a slow blade
speed.)
These two or three slow cuts sufficiently lap (polish) the new blade so that it does not snag the
material being cut. Proper break-in will alleviate blade vibration, improve surface finish, accuracy, and
blade life.
After “break-in”, the following six points must be closely monitored to ensure long blade life:
1. Proper blade tension should be maintained. (see section 3, Pg 3.2 Blade Changing)
2. Generous coolant application is essential with most materials. A high quality and well mixed
coolant will extend blade life, and also increase cutting rate and quality. On those materials
where coolant is undesirable for cutting, a slight coolant flow or periodic oiling of the blade is
necessary to prevent the blade from being scored by the carbide guides.
3. The stock being cut must be securely clamped in the vises.
4. The proper feed force should be chosen. (see section 2B - Saw Cutting Parameters: Step 2)
5. The proper blade speed must be selected. (see section 2B - Saw Cutting parameters: Step 4)
6. The proper feed rate must be applied. (see section 2B - Saw Cutting Parameters: Step 5)
VARIABLE SPEED CONTROL
Blade speed can be adjusted infinitely between 75 to 400 SFM (23 to 122m/min) (Surface Feet/
Minute). Adjustment should be made only when the blade is running. Clockwise rotation of knob
increases blade speed while counter clockwise rotation decreases blade speed. If the saw is equipped
with an inverter (variable frequency drive) unit, then the blade speed is controlled with a dial on the
control panel.

PARAMETERS
CHART
A full size DOOR CHART is mounted on the drive door of the saw. The chart contains five steps
for the operator to follow in order to achieve optimum performance of the saw.
Saw Cutting Parameters Door Chart
DOOR CHART EXAMPLE #1
We will use the door chart to set up the saw for cutting 8" (200mm) Diameter #1045 Carbon Steel.
STEP 1
DETERMINE EFFECTIVE MATERIAL WIDTH -
W ( inches ) or (mm)
Effective material width, W (in.) for most common shapes of materials, is the widest solid part of
the material to be in contact with blade during cutting. For simple shapes, as illustrated on the chart, this
can be directly measured. For bundles of tubes and structurals, measuring the effective width is
difficult. Effective width is 60% to 75% of the actual material width.
Material Width Chart
NOTES:
1) Both effective material width and guide arm width are used in setting the saw.
2) Guide arm width is the distance between the guide arms and is used in STEP 2.
3) Effective material width, as determined here in STEP 1, can be thought of as the
average width of material “seen” by each tooth, and it is used in STEPS 3 and 4. In Example #1,
for an 8" (200 mm) diameter solid, Effective Material Width is 8" (200mm).
Pg 2.15
STEP 2
SET FEED FORCE LIMIT
The Feed Force Limit is the maximum amount of force with which the head is allowed to push the
blade into the work-piece.
FEED FORCE LIMIT should be set with the head in the down mode, according to the label.
CUTTING SOLIDS
For cutting solids, the wider the section, the less FF should be set, to avoid blade
overloading. See the graph below.
EXAMPLE: When cutting a solid which is 1/2 of machine capacity using the graph, locate 50% on
the horizontal line and travel upwards to the plotted line and then travel directly across to the vertical FF
Setting line. The point that you have arrived at shows a setting of 40% for a piece 50% of capacity.
CUTTING STRUCTURALS
A reduced Feed Force Setting is used when cutting structurals:
For structurals, a blade finer than Optimum can be used for more efficient cutting.
If a finer than optimum blade is going to be used;
Feed Force Setting should be reduced even further.

STEP 3
DETERMINE OPTIMUM BLADE PITCH - TEETH PER INCH (T.P.I.)
Selecting a blade with proper tooth pitch is important in order to achieve optimal cutting rates
and good blade life.
For cutting narrow or thin wall structural materials a fine blade with many teeth per inch (T.P.I.) is
recommended. For wide materials a blade with a coarse pitch should be used. See the sketch below for
the blade pitch changes for differing effective material widths.
Optimum Blade Pitch ( T.P.I. ) for Material Width ( Inches )
It is impractical to change the blade to the proper pitch every time a different width of material is
cut and it is not necessary, but remember that the optimum blade will cut most efficiently. Too fine a
blade must be fed slower on wide material because the small gullets between the teeth will get packed
with chips before they get across and out of the cut. Too coarse a blade must be fed slower because it
has fewer teeth cutting and there is a limit to the depth of a cut taken by each tooth. Allowance for the
use of a non-optimum blade is made in STEP 5.
In our Example #1 :
Effective material width of 8" (200 mm)
Optimum blade has 2/3 teeth per inch.
Pg 2.17
STEP 4
DETERMINE OPTIMUM BLADE SPEED, V (ft/min) (m/min)
The relationship between optimum blade speed and effective material width for various
materials is represented on the graph shown.
Optimum Blade Speed Curves
The graph shows that as effective material width gets wider or as material gets harder, lower blade
speeds are recommended. If material is narrow or soft, higher blades speeds should be selected.
In Example #1
- 8" (200mm) diameter #1045 Medium Carbon Steel solid bar is to be cut.
- On the graph above find the Medium Carbon Steel Curve which represents the optimum blade
speeds for 1045 Carbon Steel.
- On the horizontal axis (effective material width axis) find number 8 which represents effective
material width of an 8" (200mm) diameter solid.
- Find the point where a vertical line from 8" (200mm) intersects the Medium Carbon Steel Curve.
- From this intersection point run horizontally left to the vertical axis (optimum blade speed axis)
and find the point marked “200”.
For 8" (200mm) diameter, 1045 Carbon Steel solid bar 200 ft/min (60m/min) is the optimum
blade speed.
NOTE: 1. Higher than optimum blade speed will cause rapid blade dulling. Lower than optimum blade
speeds reduce cutting rates proportionately and do not result in significantly longer blade life
except where there is a vibration problem. If the blade vibrates appreciably at optimum speed as
most often occurs with structurals and bundles, a lower blade speed may reduce vibration and
prevent premature blade failure.
Pg 2.18
2. Material Hardness - The graph above illustrates blade speed curves for materials of hardness
20 RC (225 Bhn) or lower. If the material is hardened then the multipliers need to be used. These
multipliers are given in the NOTE at the bottom right of the graph. As the hardness increases the
optimum blade speed decreases.

Materials and Blade Speed
DETERMINE FEED RATE SETTING, FR (in/min) (mm/min)
Feed Rate Knob
FEED RATE is the vertical speed at which the blade descends through the work-piece.
The FEED RATE Knob controls FEED RATE of the blade descent in the range 0 to 15 in/min
(380mm/min). The FEED RATE should be adjusted only in one direction (from “O” to required value). If
you go too far, go back to “O” and come back up. To set FEED RATE for particular cutting situations use
the Graph below, which represents the relationship between FEED RATE, blade speed and blade pitch.
For Example #1, it is known from Step 3 that optimum
blade pitch is 2/3, and from Step 4 that blade speed,
is 200 ft/min (60mm/min). From the Graph on the left,
the FEED RATE is determined in the following way:
- On the horizontal axis (blade speed axis), find 200 ft/
min(60mm/min). - Find the point where a vertical line
from 200 ft/min (60mm/min) would intersect the 2/3
blade pitch curve.
- From this intersection point run horizontally left to
the vertical (FEED RATE) axis, to arrive at 1.8 in/min
(45mm/min) FEED RATE. Thus 1.8 in/min (45mm/min)
is the FEED RATE for cutting 8" (200mm) diameter
1045 Carbon Steel when the optimum 2/3 pitch blade
is used.
Feed Rate Calculation
Pg 2.19
Feed Rate, CONTINUED
If the saw is fitted with a blade coarser than optimum (e.g.. 1.4/2.5 TPI) we can still use the graph,
but we go to the 1.4/2.5 curve. As a result we find that the FEED RATE is decreased to 1.3 in/min
(133mm/min) for this blade. If however, the machine is fitted with a finer than optimum blade (e.g.. 3/4
TPI) we use the graph for the optimum blade as before, and then use a multiplier given by the table below.

A generous flow of coolant should be applied in order to increase production and blade life. The
machine is provided with two independently controlled coolant spouts. One is on the adjustable guide
arm, this one should always flood the blade with coolant. Slight readjustment may be required when
changing the blade speed. A properly adjusted flow of coolant should cover the blade which in turn will
carry it into the cutting area. The flow adjusting tap is shown below. The second is mounted on the fence
for the coolant hose which should be used in cases when cutting solid bars, bundles or wide structurals.
The flow of coolant should be directed into the opening created by the blade.
NOTE: When cutting materials that do not need coolant (cast iron) some coolant flow is required to
provide blade lubrication to prevent blade scoring by carbides.

The blade brush, located behind the drive wheel door, is properly set when the machine leaves the
factory, but it wears out during operation and needs to be readjusted periodically. The plastic drive
wheel that is driven by the drive wheel face should be held against the blade face with the minimum force
that is necessary. As the blade brush wears it is necessary to periodically adjust it closer to the blade or
if a new brush is installed, further away from the blade.
As shown below, there are two springs on socket head screws holding the brush assembly gainst
the blade. There is also an adjusting socket set screw with a hex nut on it. Loosen the hex nut with a 9/16"
wrench and turn the set screw counter clockwise with a 3/16" allen key. This will move the brush closer to

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 the tank return line . The element should be changed after the first 50 Hours of operation and then
every 500 working hours. Suitable replacement elements are:
CANFLO
RSE-30-10
GRESEN
K-22001
PARKER
921999
ZINGA
AE-10
2.
OIL LEVEL - Oil level should be maintained in the upper half of the level gauge. Normally the rate
of oil consumption will be very low and it should be unnecessary to add oil more often than at filter
changes. Add oil only to the top line on level gauge.
The M-16, M-20 is shipped from the factory with Texaco Rando HD 46 hydraulic oil. Generally any
brand of recognized mineral hydraulic oil with the same properties should be compatible with Duro
AW46, but to avoid any risk we suggest staying with Rando HD 46. If it is desired to change brands, it is
necessary to drain the tank and 1/3 refill it with the new oil, operate through several full strokes of each
cylinder, drain the tank again, and finally fill the tank with the new brand.
Hydraulic tank capacity is approximately 11 US gallons (42 L).
Recommended replacement oils for Texaco Rando HD 46:
Chevron
AW Hydraulic Oil 46
Esso
NUTO H46
Mobil
Mobil DEC 25
Shell
Tellus 46
3.
OIL TEMPERATURE - Oil temperature is indicated by a thermometer contained in the level gauge
. Oil temperature 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 should never exceed 160 F° (70°C)
4.
OIL PRESSURE - Oil pressure is factory set to 900 PSI (6200 kPa) and should not require further
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.
CLEANLINESS
The M-16, M-20 heavy duty design should endure heavy operating conditions and provide the
customer with flawless machine 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.

warning will be displayed on the interface when the battery drains to a certain level. Battaries can be
purchased through your Hyd-Mech Distibutor.
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 and sawing 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 the PLC. A proximity switch and target, mounted to the gearbox drive pulley or behind idler
wheel, provides blade speed input to the PLC.
The programmed information includes logic put into the PLC be its manufacturer, as well as
information programmed in, through the keypad, by the assembly plant. Information from the assembly
plant is referred to as the parameters. The parameters are important for the PLC to provide accurate
sawing lengths and blade speed display. 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

simultaneously ( not more than 0.5 sec. apart). The PLC will prompt for a password which is obtainable
from Hyd-Mech Saws. If the password 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 is necessary, follow the calibration procedure on page 3.20. To
move through the parameters use the cursor keys to scroll up or down. To change a parameter, cursor to
that parameter line, and, using the number keys, type in the new value and press enter. To leave the

PLC is not measuring lengths.
USES;
POSSIBLE CA
CAUSES;
i) Encoder

DIA
GNOSIS;
DIAGNOSIS;
I)
With the machine in MANUAL mode; bring the shuttle forward to the home position and
clear the length display to read '0.000'. Run the shuttle, in slow speed, to the rear then back
to home, moving full shuttle strokes.
- length should accumulate on the display as a positive number when the shuttle moves
away from the blade 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 channels is not being recorded correctly.
ii)
To determine the cause, first, check the encoder cable connections at both ends to be sure
all four wires are connected properly. (See page 3.18 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 supply voltage at each channel.
If voltage is incorrect at this point, check for proper continuity of these wires and repair as
necessary.
NOTE:
c)
When checking the encoder cable for continuity, each wire should also be
checked for shorting to ground and shorting to each other.
If voltage to the encoder is correct; go to Step C).
At the encoder connection of the PLC; - between 0 V and A&B channels.
With the shuttle moving slow, voltage should be approximately 10 -13 VDC. Input LED's
X0 and X1 should flicker or go dim with the shuttle moving. If these LED's show no
change with the shuttle moving, the encoder is likely at fault. Check that the pinion gear is
securely fastened to the encoder shaft and that it can rotate 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.

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 shaft
ii) Encoder Cable - bad connection at encoder or at PLC

GENERAL R
ULES
RULES
1) Inconsistent
Cause:
2) Consistent
Cause:
3) Linear
Cause:
- Normally, three types of length inaccuracies may occur.
- lengths cut are not consistent, error changes. It doesn't matter how long the
part required is the error is never the same.
- most likely a defective electrical, hydraulic or mechanical component.
- lengths cut are consistent and the error is also consistent. The error always
stays the same regardless of part length.
- Kerf value
- lengths cut are consistent but the error increases as the part length increases.
The longer the part the greater the error.
- when self-calibration is executed, incorrect "Act Lth" value entered
DIA
GNOSIS;
DIAGNOSIS;
i)
Check and record existing parameters. Also check for proper blade kerf.
By making a cut part way into a piece 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
length display. 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 this test several times to be sure the read-out is repeatable.
DIA
GNOSIS;
DIAGNOSIS;
iii)
Following the same procedure, run the shuttle alternating between fast and slow speed going
back and coming 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 rack teeth 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 no binding or rough spots felt when spinning the shaft. Plug the encoder cable into
the encoder, clear the length display, and rotate the shaft exactly (or as close as possible) one
revolution. The display should read approximately 3.142" (positive or negative). Repeat this 3
or 4 times, spinning the shaft several times between tries.
Pg 3. 12
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 pieces of 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
and closes. It should equal the required length plus the programmed kerf value. Check
that this measurement is +/-.002" for each length.
If the overshoot /undershoot is very inconsistent, it could be related to an incorrect shuttle
cushion period. This may be caused by "Decel. Dist." parameter being set too low,
defective fast or reverse output relays on the PLC, or the hydraulic cushion valve (located
at the hydraulic manifold) may be faulty.
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 3.20)
- re-enter new ACT LTH (Actual Length) value
- recut test lengths and check if accuracy is satisfactory.

After the mode push button is in the AUTO position and the job has been
Programmed into the PLC, and the Cycle Start push button pressed:
Hydraulics running, the head should move to it's up limit, if it is not already there. Shuttle
vise should open and 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.
Front vise should be closed, the shuttle vise should stay open and move back to the
programmed length;
FVC output should be on SVO output will light momentarily, REV output and FST output
should be on when the shuttle moves back fast.
As the shuttle approaches target length the FST output should shut off and the shuttle
should travel slow for the "Dec. Dist." parameter, cushion distance. (i.e. 1.00") When
the shuttle reaches target length, the SVC output should light, and the shuttle vise
should close on the material.
FVO output light should come monetarily on and front vise should open.
FWD output should light as will as FST for the shuttle to move forward in fast speed. FST
will turn off when the shuttle home cushion period is reached and the shuttle should
slow down into the home position.
FVC output should light and the front vise should close. FWD light should go out, HDN
output should come on and the head should start to descend for the cut. If blade is not
running at this time, auto cycle will hold until min. SFM is reached. Depending on "Hld
Shtl Hm" parameter in the PLC, the shuttle may stay home and closed during the cut or
may move back to pick up the next length. HUP input should go out as the head
descends, and HUP L/S deactivates.
7)
After the cut is completed HDN input should light, HDN output should go out, the HUP
output should light and the head should move up. When the head reaches it's up limit, HUP input
should come on, RHD output off and the cycle repeats with the next length being clamped on by
the shuttle, front vise opening and the length being brought forward to home position.
As mentioned, beside each input and output terminal there is a bank of red LEDs. Each light
corresponds to its input or output. An input LED will light when it's specific input signal is being received
at the PLC and output LED'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/stuck or the output (3 amp) fuse has blown. (See fuse information
below) If a fuse is blown, a shorted directional valve coil (good coil should measure 30 to 40 ohms),
shorted noise suppresser at the coil, or shorted wiring could be the cause. If the fuse is good and no
output voltage condition still exists, with the output light on, then the relay is defective. 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 input terminal 'L'.
Fuses 'F2' to 'F5' are 3 amp time delay fuses which each supply power to a specific bank
of output relays through that bank of relay's 'COM' terminal:
F2 is wired to terminal 'COM 1' supplying Outputs
F3 to terminal 'COM 2' supplying Outputs
F4 to terminal 'COM 3' supplying Outputs
F5 to terminal 'COM 4' supplying Outputs

iii)
Faulty connection of cable between PLC & Interface
DIAGNOSIS;
i)
Check POWER LED (see page 3.17 - 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.
Pg 3.15
PROBLEM # 5
No Blade Speed Display.
POSSIBLE CAUSES;
i) Fault at proximity sender
ii) Fault at the PLC
- bad sender, misadjusted sender (gap should be approx. 0.015")
- contamination on the end of the sender
- bad connection of sender wiring
- faulty PLC input
DIAGNOSIS;
i)
Pg 3. 16
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 blade running, proximity LED should pulse. Likewise, the PLC input LED
(X2) should be pulsing. If both LED's are pulsing 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

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 trim cut is made the head will rise, the shuttle will retract fully in slow,
clamp the material and come fully forward in slow to the home position and make a cut. After the cut is
complete "1" will change back to "0". Measure the cut part length.
Cursor down to ACT.LTH. and enter length of cut part plus the actual kerf value. Then exit
the parameters by toggling the AUTO/MAN button or put the front VISE in the hold position (the cycle
start button will stop flashing). The ENC.RES. & full stroke values will now automatically be calculated
and programmed by the PLC.
*NOTE:
When first entering the parameters screen if not running the self
calibration do not use the enter key 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
programmed length 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
LENGTH parameter. This may be done with material in the machine (cut and measure
material length) or with no material 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 be increased.
- If part length error gets shorter as the programmed length increases; ACTUAL LENGTH value
should be decreased.
- 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"

CALIBRATION
1)
Enter the PLC parameter screen as per Length Calibration Procedure on Pg. 3.19.
2)
Using the arrow cursor keys scroll down until the screen displays :
HT CLB "ENTER"
ACT HT
0
00.000
3)
With the cursor on the 0 , press the ENTER key. The cycle start button will begin to
flash, the head will 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 the ACT HT parameter. Measurement must be made along the front vise
datum jaw.

GENERAL INFORMA
TION
INFORMATION
As supplied, the machine is set to run on the three phase voltage as indicated on the serial plate
and voltage label. Power connection to the machine is made to the main disconnect switch and the Ll,
L2, L3 and Ground terminals. The disconnect switch box is located on right side of the Operator Control
Panel.
In order to use the machine on a different supply voltage the following changes must be made:
1. Change the blade motor (or if equipped with a dual voltage motor, rewire it)
2. Change the hydraulic pump motor (or if equipped with dual voltage motor, rewire it)
3. Change the control transformer.
4. Change the blade and pump motor overloads, located adjacent to the contactor, to suit the
full load current of the new or rewired motor.
All other components are supplied from the control transformer and operate on 115V, single
phase. They do not need altering.
The machine is supplied for use on a 60HZ or 50Hz supply.
WHEN CHANGING THE SUPPLY VOLTAGE, CAREFULLY OBSERVE THE ABOVE STEPS. THESE
STEPS ARE ESSENTIAL TO AVOID SEVERE DAMAGE TO THE MOTORS AND CONTROLS.
At initial hook-up it is important to check that the phase order is correct. This is indicated by the
blade drive wheel revolving in a counter clockwise direction and the hydraulic pressure gauge
registering a pressure rise. On the following pages are the electrical schematics and physical wiring
diagrams along with a list and photos of electrical components.
NO
TE: 1)The PLC is equipped with a lithium battery to keep the program stored while the power
NOTE:
is shut down. The battery will need to be replaced every 3 to 5 years, depending on usage. A visual
warning will be displayed on the interface when the battery drains to a certain level. Battaries can be
purchased through your Hyd-Mech Distibutor.
2) If the machine is equiped with an inverter, do not turn disconnect on for 3 three
minutes after disconnect has been 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 is placed near the interface in order to reduce "noise"

ASSEMBLY
SECTION 7, OPTIONS
For customers who cut bundles, a bundling vise is available. For "P" model machines, only one
bundling assembly is required for the single vise, an "A" model is shown below. When cutting a number of
pieces at once, the vertical clamp holds the bundle down firmly to prevent cutting errors due to material
slippage or vibration. This also helps to extend blade life.

This option is shown with the standard vises closed and the
BUNDLING VISES OPEN.
