ELECTROMAGNETIC COMPATIBILITY (EMC)

Earthing of workpiece
Where the workpiece is not bonded to earth for electrical
safety, nor connected to earth because of its size and
position, for example, ship’s hull or building steelwork, a
connection bonding the workpiece to earth may reduce
emissions in some, but not all instances. Care should be
taken to prevent the earthing of the workpiece increasing
the risk of injury to users, or damage to other electrical
equipment. Where necessary, the connection of the
workpiece to earth should be made by a direct
connection to the workpiece, but in some countries where
direct connection is not permitted, the bonding should be
achieved by suitable capacitances selected according to
national regulations.

Note: the cutting circuit may or may not be earthed for

safety reasons. Changing the earthing arrangements
should only be authorized by a person who is competent
to assess whether the changes will increase the risk of
injury, for example, by allowing parallel cutting current
return paths which may damage the earth circuits of other
equipment. Further guidance is given in IEC/TS 62081
Arc Welding Equipment Installation and Use.

Screening and shielding

Selective screening and shielding of other cables
and equipment in the surrounding area may alleviate
problems of interference. Screening of the entire
plasma cutting installation may be considered for
special applications.

 SAFETY

Dry dust collection information

At some sites, dry dust can represent a potential explosion hazard.

The U.S. National Fire Protection Association’s 2007 edition of NFPA standard 68, “Explosion Protection by
Deflagration Venting,” provides requirements for the design, location, installation, maintenance, and use of devices and
systems to vent combustion gases and pressures after any deflagration event. Consult with the manufacturer or installer
of any dry dust collection system for applicable requirements before you install a new dry dust collection system or make
significant changes in the process or materials used with an existing dry dust collection system.

Consult your local “Authority Having Jurisdiction” (AHJ) to determine whether any edition of NFPA 68 has been
“adopted by reference” in your local building codes.

Refer to NFPA68 for definitions and explanations of regulatory terms such as deflagration, AHJ, adopted by reference,
the Kst value, deflagration index, and other terms.

Note 1 – Hypertherm’s interpretation of these new requirements is that unless a site-specific evaluation has been
completed to determine that all dust generated is not combustible, the 2007 edition of NFPA 68 requires the use of
explosion vents designed to the worst-case Kst value (see annex F) that could be generated from dust so that the
explosion vent size and type can be designed. NFPA 68 does not specifically identify plasma cutting or other thermal
cutting processes as requiring deflagration venting systems, but it does apply these new requirements to all dry dust
collection systems.

Note 2 – Users of Hypertherm manuals should consult and comply with all applicable federal, state, and local laws and
regulations. Hypertherm does not, by the publication of any Hypertherm manual, intend to urge action that is not in
compliance with all applicable regulations and standards, and this manual may never be construed as doing so.

• Ne jamais pointer la torche vers soi ou d’autres personnes.

LES RAYONS DE L’ARC PEUVENT BRÛLER LES YEUX ET LA PEAU

Protection des yeux Les rayons de l’arc plasma produisent de puissants rayons visibles ou invisibles (ultraviolets et infrarouges)
qui peuvent brûler les yeux et la peau.
• Utiliser des lunettes de sécurité conformément aux codes locaux ou nationaux en vigueur.
• Porter des lunettes de protection (lunettes ou masque muni d’écrans latéraux et encore masque de soudure) avec des verres
teintés appropriés pour protéger les yeux des rayons ultraviolets et infrarouges de l’arc.

Protection de la peau Porter des vêtements de sécurité pour se protéger contre les brûlures que peuvent causer les rayons
ultraviolets, les étincelles et le métal brûlant :
• Gants à crispin, chaussures et casque de sécurité.
• Vêtements ignifuges couvrant toutes les parties exposées du corps.
• Pantalon sans revers pour éviter que des étincelles ou des scories puissent s’y loger.
• Avant le coupage, retirer de ses poches tout objet combustible comme les briquets au butane ou les allumettes.
Zone de coupage Préparer la zone de coupage afin de réduire la réverbération et la transmission de la lumière ultraviolette :
• Peindre les murs et autres surfaces de couleur sombre pour réduire la réflexion de la lumière.
• Utiliser des écrans et autres dispositifs de protection afin de protéger les autres personnes de la lumière et de la réverbération.

Information sur le dépoussiérage

À certains endroits, la poussière peut représenter un risque d’explosion potentiel.À certains endroits, la poussière peut
représenter un risque d’explosion potentiel.

La norme NFPA 68 de la National Fire Protection Association des É.-U. (édition 2007) « Explosion Protection by
Deflagration Venting » établit les exigences relatives à la conception, à l’emplacement, à l’installation, à l’entretien et à
l’utilisation de dispositifs et de systèmes pour évacuer à l’air libre les gaz de combustion et les pressions après une
éventuelle déflagration. Communiquer avec le fabricant ou avec l’installateur pour tout système de dépoussiérage afin
de connaître les exigences applicables avant d’installer un tel système neuf ou d’apporter des modifications importantes
aux procédés ou aux matériaux utilisés à un système de dépoussiérage existant.

Consultez l’autorité compétente locale pour déterminer si une édition de la NFPA 68 a été adoptée par référence dans
vos codes du bâtiment locaux.

Voir le document NFPA68 pour obtenir des définitions et des explications des termes réglementaires tels que «
déflagration, autorité compétente, adopté par référence, valeur du pire cas, indice de déflagration » et autres termes.

Note 1 – L’interprétation d’Hypertherm de ces nouvelles exigences est que, sauf évaluation particulière du site, pour
déterminer que toute la poussière produite n’est pas combustible, l’édition 2007 de la NFPA 68 exige l’utilisation
d’évents d’explosion conçus pour la valeur du pire des cas (voir annexe F) qui pourrait provenir de la poussière de sorte
que l’on puisse concevoir la dimension et le type d’évent d’explosion. La NFPA 68 ne stipule pas particulièrement le
procédé de coupage plasma particulier ou autres procédés de coupage thermique comme le prescrivent ces nouveaux
règlements à tous les systèmes de dépoussiérage.

Note 2 – Les utilisateurs des manuels d’Hypertherm doivent consulter tous les règlements et lois fédéraux et locaux
applicables et s’y conformer. Hypertherm n’a pas l’intention, en publiant un manuel d’Hypertherm, de demander des
mesures qui ne sont pas conformes aux règlements et normes applicables et ce manuel ne peut jamais être interprété
dans ce sens.

Información sobre la colección de polvo seco

En algunos sitios, el polvo seco puede representar un peligro potencial de explosión.

La edición del 2007 de “U.S. National Fire Protection Association” iniciales en inglés NFPA (La Asociación Americana
Nacional de Protección Contra Incendios) del estándar 68 “Protección de Explosión por medio de Respiradero de
Deflagración” proporciona requisitos para el diseño, ubicación, instalación, mantenimiento, y uso de aparatos y sistemas
para dar salida a gases de combustión y presiones después de todo evento de deflagración. Consulte con el fabricante
o instalador de cualquier sistema de colección de polvo seco para los requisitos aplicables antes de que instale un
sistema nuevo de colección de polvo seco, o haga cambios significativos en el proceso o materiales que se usen con
un sistema existente de colección de polvo seco.

Consulte su “Autoridad que Tenga Jurisdicción” (iniciales en inglés AHJ) local para determinar si cualquier edición
de la NFPA 68 ha sido “adoptada por referencia” en los códigos de construcción locales.

Remítase a la NFPA 68 para definiciones y explicaciones de los términos reguladores como “deflagración, AHJ,
adoptada por referencia, el valor Kst, índice de deflagración” y otros términos.

Nota 1 – La interpretación de Hypertherm de estos nuevos requisitos es que, a no ser que se haya completado una
evaluación específica del sitio para determinar que todo polvo generado no es combustible, la edición del 2007 de
la NFPA 68 requiere el uso de respiraderos de explosión diseñados para el peor caso del valor Kst (vea anexo F) que
pudiera ser generado por el polvo, de manera que el tamaño y tipo del respiradero de explosión pueda diseñarse.
La NFPA 68 no identifica específicamente corte por plasma u otros procesos de cortes termales como si requirieran
sistemas de respiraderos de deflagración, pero en realidad aplica estos nuevos requisitos a todos los sistemas de
colección de polvos secos.

Nota 2 – Los usuarios de los manuales de Hypertherm deberían consultar y cumplir con todas las leyes y reglamentos
federales, estatales y locales aplicables. Hypertherm, al publicar todo manual de Hypertherm, no intenta urgir acción
que no esté en cumplimiento con todos los reglamentos y normas, y este manual nunca debe interpretarse como si lo
hiciera así.

 SPECIFICATIONS

General
Hypertherm’s X-Y CommandTHC is a torch height control/initial height sensing (THC/IHS) system designed for plasma
cutting applications on a X-Y cutting table (Figure 2-1). The system uses the plasma arc voltage to control the physical
stand-off (distance) between the torch and workpiece during plasma arc cutting. IHS is accomplished by ohmic contact
sensing or by a limited force stall detection method. The system includes the following:

• THC control module (Figure 2-2) The THC control module houses 2 microcontrollers, a realtime controller
and an interface controller. This unit provides initial height sensing, arc voltage control and interfaces with
the torch lifter, the CNC machine, operator pendant and the plasma power supply through standard discrete
I/O interfaces and optional extended RS-422 serial interfaces.

• Plasma interface assembly with voltage divider (Figure 2-3) The plasma interface houses an interface
PCB which provides a communications link between the THC control module and the plasma power supply.
The voltage divider provides a 41 : 1 signal which is derived from the cutting arc voltage. For example, if the arc
voltage is 150 volts, the resultant 3.66-volt output signal is used to control the stand-off distance between the
torch and workpiece during plasma cutting.
Note: HyPerformance (HPR) plasma systems do not have an interface assembly. HPR systems have an
interface board that mounts in the power supply.

• X-Y lifter assembly (Figure 2-4) The torch lifter station, under control of the THC control module, positions a
torch head vertically above the workpiece. Its maximum stroke is 8 inches (200 mm) between the home and
lower limit switches. It is driven by a stepper motor attached to a leadscrew. An encoder is provided for stall
IHS sensing, and to detect gross errors during normal operation. A lower limit switch detects maximum travel
in the downward direction. A home switch is provided to detect when the lifter is in the uppermost position.
A power-off brake is energized after power up, and allows controlled motion of the torch. It is powered off during
“Maintenance Mode” to prevent the torch from being accidentally moved. An optional torch breakaway kit is
also available.

• Operator pendant (optional) (Figure 2-5) The operator pendant is a remote control which includes an
LCD display and keypad used for THC setup and control (parameter entry and menu selection).

• Torch breakaway kit (optional) (Figure 2-6) The torch breakaway (collision sensor) provides a level of
protection for the torch, lifter and X-Y table. Air pressure locks the torch to the THC lifter assembly. The air
pressure can be adjusted to change the force required to trip the breakaway. Upon side impact, the breakaway
releases from the lock position and allows the torch to float. See Figure 2-4 for torch mounting dimensions with
and with out the breakaway.

1. Mount the fiberglass bracket to the X-Y lifter using the 4 hex screws.

2. Mount the breakaway to fiberglass bracket using the 6 screws.

3. Attach the torch mounting block to the breakaway with the collar and 2 screws.

4. Wire the electrical output of the breakaway to the emergency stop circuit at CNC.

5. Mount the filter/regulator.

6. Connect tubing between regulator and breakaway.

7. Install air supply to the regulator inlet port at 100 psi (6.9 bar) (recommended maximum pressure).

8. Adjust the regulator to indicate 30 psi (2 bar) (recommended starting pressure) on the gauge.

9. By hand, force the breakaway to trip to simulate a crash.

Manually reposition breakaway to the lock position.

10. Adjust air pressure until the desired trip force is achieved.

11. Enable the emergency stop circuit at CNC after the breakaway is installed.

Notes:
• Installing the torch breakaway kit to the X-Y lifter assembly also requires using parts of the torch mounting block kit
of the proper diameter. Refer to Section 6, Part List for details.
• The maximum pressure regulator inlet pressure is 150 psi (10.2 bar). Typically, the maximum inlet pressure should
be set at 100 psi (6.9 bar).
• The routing of the leads, stall force, IHS speed, and acceleration/deceleration movements can affect the pressure
setting required to achieve reliable operation.
• If air pressure is removed (for example, overnight), the breakaway will have to be manually repositioned when air is
applied. The breakaway will not rest in its position when air pressure is lost.

THC selectable responses

The DIP switch, on the motor drive board, provides adjustable arc voltage control response.

DANGER
ELECTRIC SHOCK CAN KILL

Turn off all electrical power before removing the power supply cover. Press the power
supply OFF (0) pushbutton switch and set the line disconnect switch to OFF. In the
U.S., use a “lock-out and tag-out” procedure until the service or maintenance is
complete. In other countries, follow appropriate local or national safety procedures.

Remove the THC control module cover to access the

DIP switch on the motor drive board.

 SETUP

DIP switch positions

1 Fast/Slow response
• ON slows response speed of lifter by approximately one half in both up and down directions.
• OFF enables "normal" or fast response.

2 Conventional/HyDefinition resolution
• ON enables the THC to respond to larger voltage error changes.
• OFF enables the THC to respond to smaller error voltage changes.

3 Limited down speed

• ON enables lifter to move up at the normal speed, but down at slower speed. This is designed to help where
corner diving is a problem.
• OFF enables the lifter to move up and down at the "normal" speed.

CommandTHC serial protocol

Commands can be sent over a serial link to control the function of the torch height control. The interface is 4 wire
RS422 on the MACHINE INTERFACE CABLE (pins (1) RX–, (20) RX+, (2) TX–, (21) TX+).
The serial frame runs at:
Old protocol (041507 control PCB) – 9600 baud, 8 data bits, 2 stop bits, and even parity
New protocol (041706 control PCB) – 19200 baud, 8 data bits, 1 stop bit, and no parity
All bytes in a serial message are ASCII characters. A message consists of a start of message character (>, 0x3E),
2 byte message ID (all message ID’s should be capitalized), variable length data, 2 byte checksum, and end of message
character (<, 0x3C). For example to put the THC into remote mode >RM1D0<. ‘RM’ is the message ID, ‘1’ is the data
field, and 0xD0 is the checksum (2 hex digits sent as 2 ASCII characters). The response to an accepted command is
(^, 0x5E) and the response to an invalid command is (#, 0x23).

Some of the commands can be queried by using (?, 0x3F) as the data. For example to query the actual arc voltage
>AV?D6<. The response to this query would be >AV100058<, which represents an actual arc voltage of 100.0 volts
with a checksum of 0x58.

Errors can be retrieved over the serial link. There is a discrete output on the machine interface cable (THC Error pins
14,33) which indicates an error has occurred. Using the command >CL8F< errors can be cleared and retrieved.
A typical response might be >ERR-Motor Current Fault46< or if there is no error (^, 0x5E) is returned.

 SETUP

Application notes:
1. To do manual movements Jog up, down and Step up, down the THC must be in manual mode (Automatic Voltage
Control = 0).
2. When the THC receives a Jog up or down command, it will move the torch up/down for 50 milliseconds. If a new
command is not received after this time the motion will stop. To achieve continuous movement the Jog command
must be repeatedly sent faster than once every 50 milliseconds.
3. The Error code command will ONLY retrieve an error code, it will not clear an error. To clear an error the CL (Clear
error command must be sent).
4. The revision commands (RR and RI) return the decimal representations of the revisions that are stored (as ASCII
characters) in the firmware.
5. Setting the Retract distance (RH) only applies when the THC is in partial retract (Retract = 1).
6. To force the lifter station to go home send the following series of commands : RE1, RE0 (partial retract, then full
retract this will force a homing sequence).

Error codes:
Code Error string
0 “ERR-Torch is in LOWER LIMIT”
1 “ERR-Torch is in HOME LIMIT”
2 “ERR-EEPROM checksum Error”
3 “ERR-Lifter NOT Installed”
4 “ERR-Motion FAIL”
5 “ERR-Watch Dog Timeout FAIL”
6 “ERR-InterProcessor Comm Fail”

The following fields can be changed to adjust system operating parameters.

Automatic Operation Screen

Set Arc Volts Sets the automatic voltage control (AVC) setpoint. Set Arc Volts can be changed
any time (stationary or during a cut). When the AUTO mode is selected and after
the Pierce Delay and Machine Accel Delay times have elapsed, the arc voltage is
controlled by the THC (torch height). The THC adjusts the torch height during a
cut, to maintain the Set Arc Volts.

Small change: +/– 0.5 V

Large change: +/– 5 V

Setpoint range: 50–300 V

Set Cut Height Sets the initial cutting height before AVC is activated. Also sets the pierce height.
See Determining Pierce Height Factor later in this section.

During a normal cut cycle, the torch will move down and sense the workpiece, and
then retract to the Pierce Height. At this point the THC will issue a “Start” signal to
the plasma system and wait for a “Transfer” signal. The torch will move to the
Set Cut Height after the Pierce Delay time has elapsed.

Small change: +/– 0.010 inch/0.2 mm

Large change: +/– 0.100 inch/2 mm

Setpoint range: 0.010–1 inch (0.25–25.4 mm)

4-6 CommandTHC for X-Y Table Instruction Manual

 OPERATION

Pierce Delay Sets Pierce Delay (motion dwell time). After receiving the “Transfer” signal from the
plasma system, the THC will delay both the “Machine Motion” and the “Pierce
Complete” signals during the pierce delay time. After the “Pierce Delay” time, the
“Machine Motion” output will become active and the cutting machine will begin to
move. At the same time, the torch height will rapidly adjust to the Set Cut Height
setting and the Machine Accel Delay will begin.

Note: For best performance, use the THC pierce delay, not the CNC pierce delay.
The Pierce Complete signal only applies to HyDefinition plasma systems.

Small change: +/– 0.010 second

Large change: +/– 0.100 second

Setpoint range: 0–9 seconds

Retract Selects Retract to FULL or to a programmed value set by the operator. In the FULL
mode, the torch will retract to the home position (full up).

A retract distance that is too low will increase the risk of a torch collision when
moving to a new cutting position.

Small change: +/– 0.050 inch/1.27 mm

Large change: +/– 0.50 inch/12.7 mm

Setpoint range: 0–8 inches (0.0–203 mm)

IHS Selects IHS TEST (no plasma arc) or RUN mode. This control is used to test the
IHS without firing the torch. When IHS TEST is selected, the torch will sense the
workpiece (with ohmic contact sensing or limited force stall sensing) and then
retract to the piercing height. Then when IHS RUN is selected, the torch will
retract to the set retract height. After testing, return to the RUN mode for proper
cutting operation.

Pierce Height Factor A percent value used to calculate the pierce height.
During a normal cut cycle, the torch will move down and sense the workpiece,
then retract to the Pierce Height (Set Cut Height X Pierce Height Factor). At this
point the THC will issue a “Start” signal to the plasma system and wait for a
“Transfer” signal.

See Determining Pierce Height Factor later in this section.

Stall Force Sets the lifter downward force during the IHS cycle. This value is a compromise
between IHS speed, accuracy and lifter load capacity. Normally this value is set to
the lowest force that will reliably move the lifter at the set IHS Speed. This setting
will result in the least plate deflection and the greatest IHS accuracy.

This limited-force-stall sensing is the backup mode to the ohmic contact plate
sensing. System will default to limited-force-stall sensing if the Nozzle Ohmic
Contact is set to OFF.

The use of Stall Force sensing is not as accurate as ohmic contact sensing.
To compensate for plate deflection, the user may need to increase the values for
Set Cut Height and/or Pierce Height Factor.

Setpoint range: Relative value between

1 (minimum) and 10 (maximum)

IHS Speed Sets the lifter downward speed during the IHS cycle. This value is a compromise
between lifter speed and IHS accuracy.

Note: At lower speeds the IHS accuracy will be improved. At excessive speeds
the torch tip may be damaged and decrease IHS accuracy.

Setpoint range: Relative value between

1 (minimum) and 10 (maximum)

CommandTHC for X-Y Table Instruction Manual 4-9

OPERATION

Nozzle Contact Active HD3070, MAX200, HT2000 and HT2000LHF only. Sets ohmic contact
sensing to ON or OFF. When sensing is ON, the torch will advance to the
workpiece during IHS. The nozzle completes an electrical circuit when it
contacts the plate, providing ohmic sensing by the THC.

This parameter should remain ON for most applications. May be disabled

(OFF) to get a more reliable IHS when cutting underwater or when cutting
extremely dirty or rusty metal. Limited-stall-force sensing is always active and
provides secondary sensing to the nozzle ohmic contact sensing.

Preflow During IHS Sets Preflow During IHS to ON or OFF. When this parameter is ON, the
“Plasma Start” and “Hold Ignition” signals will be activated at the start of an
IHS cycle.

The “Hold Ignition” signal makes it possible to increase the overall machine
throughput. This is done by allowing the two normally sequential processes of
IHS and preflow to occur simultaneously. When the IHS cycle is complete
and the torch is positioned at the piercing height, the “Hold Ignition” signal is
deactivated, allowing the power supply to ignite the torch.

Note that the gas preflow time is determined by the plasma system and will
not be reduced by activating this parameter. This function occurs with no
interaction with the CNC and is totally under THC control. Some Hypertherm
power supplies may not include a “Hold Ignition” signal.

Machine Accel Delay Sets a delay to allow the cutting machine to reach a steady cutting speed
before activating the automatic voltage control (AVC). If AVC is active before
the cutting machine reaches a steady cutting speed, the torch may dive
toward the plate. During the Machine Accel Delay time, the torch will maintain
the Set Cut Height.

This delay is based on the cutting machine acceleration time to reach steady
state speed. Set this delay as low as possible without allowing the
torch to dive excessively at the beginning of the cut.

Auto Kerf Detect Sets Auto Kerf Detect to ON or OFF. Reduces the probability of the torch
diving toward the plate when the arc is crossing a kerf. When this parameter
is ON, the THC will constantly monitor the arc voltage for sudden changes. If
a sudden change is detected, the THC will assume the torch is crossing a
kerf and will maintain the torch height until the arc voltage becomes steady,
when AVC is resumed.

If the part being cut does not require crossing a kerf, this parameter should
be set to OFF (inactive).

 OPERATION

Homing Speed Sets the lifter retract (homing) speed. This value is a compromise between
machine speed and the amount of weight on the lifter. At lower speeds, the
lifter is capable of lifting heavier loads.

Setpoint range: Relative value between

1 (minimum) and 10 (maximum)

Inch or Metric Units Units can be set for inches or millimeters.

Retract Delay Sets a retract delay to allow time for the arc to ramp down and extinguish.
This time delay will start when the CNC removes the "Cycle Start" signal and
the plasma system is commanded to shutdown. After this programmed delay,
the torch will retract. Set this delay as short as possible, so that the
torch does not retract when the plasma arc is still active.

Retract Delay should be used on Hypertherm LongLife plasma systems.

Determining pierce height factor

Typical pierce height factor
See Figure 4-4 for sequence of events.

The Pierce Height Factor is a percentage of the cut height. The factor is entered into the THC pendant and the system
calculates the required pierce height. The Cut Height will be maintained until the Machine Acceleration Delay time has
elapsed, then Automatic Voltage Control will control torch height.

The default pierce height factor is 150%. Typically, this value is left at 150%.

EXAMPLE: Cut Height = 0.100 inch

Pierce Height Factor = 150%

0.100 inch X 150% = 0.150 inch*

Pierce Height = 0.150 inch

*THC system performs this calculation.

Pierce height factor for thicker materials

General: When cutting materials 3/4 inch (19 mm) or thicker, the torch may contact the molten metal
accumulated on top of the plate during piercing. See Figure 4-5. To avoid this, the cut height and
pierce height factor can be set so that the torch will jump over the molten metal after piercing is
completed.

When to apply: If the torch dives into the molten metal accumulated on top of the plate during piercing.
Do not apply if this problem is not encountered during piercing.

Application: Set the cut height to 2X the desired pierce height and enter a pierce height factor of 50%.
(These are initial settings which may be adjusted to obtain cut improvements.) After the pierce
delay, the torch will retract to the cut height for Machine Acceleration Delay (clearing the molten
metal) and then Automatic Voltage Control (AVC) will take over. See Figure 4-6 for sequence of
events.

EXAMPLE: Desired Pierce Height = 0.25 inch

Cut Height = 0.500 inch

Pierce Height Factor = 50%

0.500 inch X 50% = 0.250 inch*

Pierce Height = 0.250 inch

This signal holds arc firing until all THCs are at IHS position.

3. CNC issues a CYCLE-START-IN to THC.

4. If Preflow During IHS is enabled, THC issues a PLASMA-START-OUT and a HOLD-IGNITION-OUT

signal to plasma power supply.

5b. If Nozzle Contact (ohmic contact) is disabled, torch dives at programmed speed and stall force, until a
motor stall is detected and then retracts to pierce height

6. For multiple torch /THC installations only: THC issues IHS-COMPLETE-OUT signal to CNC. When all
IHS-COMPLETE-OUT signals have been satisfied, CNC releases IHS-SYNC-IN signal.

7. If Preflow During IHS is not enabled, THC issues a PLASMA-START-OUT signal to plasma power supply.

8. If Preflow During IHS is enabled, THC releases arc HOLD-IGNITION-OUT signal.

9. Preflow completes, if it has not already completed.

10. Torch ignites.

11. Arc transfers to workpiece. Plasma power supply issues ARC-TRANSFER-IN to THC.

12. Programmed pierce delay signal elapses.

13. Torch quickly dives from pierce height to programmed cut height; programmed MACHINE ACCEL
DELAY begins; THC issues PIERCE-COMPLETE-OUT signal to plasma power supply; and THC issues
MACHINE-MOTION-OUT signal to CNC to begin profiling part.

14. After MACHINE ACCEL DELAY elapses, arc voltage control (AVC) begins. During AVC, an AUTO-
HEIGHT-ON/OFF from CNC freezes torch position (traditional CORNER HOLD). During AVC, CNC
should issue an AUTO-HEIGHT-OFF when CNC not moving at programmed velocity. During AVC, if
AUTO KERF DETECT is enabled, torch position is frozen when crossing kerfs.

15. At end of cut, CNC releases CYCLE-START-IN signal to THC. Programmed retract delay begins.

16. Programmed retract delay time elapses and the THC raises torch until home limit switch is reached or
partial retract height is checked.

WIRING DIAGRAMS

Introduction
This section contains the wiring diagrams for the system. When tracing a signal path or referencing with the Parts List or
Troubleshooting sections, please be aware of the following format to assist you in understanding the wiring diagrams'
organization:

• Sheet numbers are located in the lower right-hand corner.

• Page-to-page referencing is done in the following manner:

SHEET
C 4-D3

Source connection Source reference block Destination sheet # Destination

coordinates

SHEET
4-D3 C

Source sheet # Source coordinates Source reference block Destination

coordinates

Destination and Source coordinates refer to letters A-D on the Y-axis of each sheet and numbers 1-4 on the
X-axis of each sheet. Lining up the coordinates will bring you to the source or destination blocks (similar to a road map).

Wiring diagram symbols

Wiring diagram symbols and their identification precede the system wiring diagrams in this section.

PENDANT CONTRAST ADJUSTMENT PROCEDURE

Under certain lighting conditions, or in cold temperatures, it may be necessary to adjust the contrast of the pendant
display for better visibility. The menu for this parameter also contains other parameters that are critical for the proper
operation of the THC. The only parameter that should be adjusted is the VIEWING ANGLE. The default settings
are listed in case it becomes necessary to reset other parameters.

The following keys on the keypad represent the function keys (F1 – F5)

F1 F2 F3 F4 F5
F1 = MAINT/MODE

F2 = AUTO/MAN.

F3 = Blank key to the right of AUTO/MAN.

F4 = RETR. MID/FULL

F5 = IHS TEST/RUN

= not used

Procedure
1. Press the SHIFT key + the MAINT/MODE key + the blank key next to the shift key at the
same time. The following options will APPEAR on the change settings menu:

F1 – CHANGE THE SETTINGS

F2 – NEXT OPTION
F3 – PREVIOUS OPTIONS
F4 – QUIT WITHOUT SAVING
F5 – SAVE & EXIT

APPENDIX B – PENDANT CONTRAST ADJUSTMENT PROCEDURE

2. Press F2 (AUTO/MAN button) until you get to the VIEWING ANGLE parameter.

3. Press F1 (MAINT/MODE button) to change the contrast setting until the display is easy to see.

4. Press F5 (IHS TEST/RUN button) to save the changes, and then press F1 (MAINT/MODE button) to acknowledge
that the change has been saved. The screen may “freeze” at this time, but will return to normal after about
15 seconds, or after a function key has been pressed.

Default pendant values

BAUD = 9600 DISABLE ECHO

DATA BITS = 8 ESCAPE MODE = ANSI

PARITY = EVEN CR/LF MODE = NORMAL
