The safety section describes general safety guidelines to be followed with this product, explanation of the
notication found in this manual, and safety precaution that apply to the product. More specic notication are
imbedded within the sections of the manual where they apply.
2.1 Explanation of Notications
The notications included here are specic to the product(s) covered by this manual. It is expected that the
user heed all notications from the robot manufacturer and/or the manufacturers of other components used
Prior to purchase and installation, the customer should verify that the Tool Changer selected is rated for the
maximum loads and moments expected during operation. Refer to product specications section in each
module of this manual or contact ATI for assistance. Particular attention should be paid to dynamic loads
caused by robot acceleration and deceleration. These forces can be many times the value of static forces in
high acceleration or deceleration situations.
The customer is responsible for ensuring that the area between the Master and Tool sides is clear of foreign
objects during mating and subsequent coupling. Failure to do so may result in serious injury to personnel.
The customer is responsible for understanding the function of the Tool Changer and implementing the
proper fasteners and/or software to operate the Tool Changer safely. The Tool Changer should be controlled
such that there is no chance of locking or unlocking in a position that would endanger personnel and/or
equipment. If the Tool Changer is specied with Lock/Unlock (L/U) and Ready-to-Lock (RTL) sensing
capability, the status should be monitored and proper interlocks applied to prevent injury to personnel and
equipment.
Document #9620-20-A-General TOC and Introduction-08
All pneumatic and uid components (i.e. ttings, tubing) must be capable of withstanding the repetitive
motions of the application without failing. The routing of electrical, uid, and pneumatic lines must
minimize the possibility of stress/strain, kinking, rupture, etc. Failure of critical electrical, uid, or
pneumatic lines to function properly may result in injury to personnel and equipment.
All electrical power, pneumatic and uid circuits should be disconnected during servicing.

3. Product Overview
3.1 Tool Changers
There are many different types of Tool Changers, Manual, Heavy Automation, Rail, Hollow Wrist, etc,
which are specically suited for the application they are designed for. A Tool Changer enhances the
exibility and reliability of a robotic cell. Robotic Tool Changers are used in automated Tool change
applications as well as manual Tool change operations. Robotic Tool Changers also provide a method for
quick Tool change for maintenance purposes.
Automatic Tool Changers provide added exibility to robot applications by allowing one robot to change
end-effectors, such as grippers and vacuum tooling. The Quick-Change products are pneumatically or
electrically operated devices consisting of a Master Plate and Tool Plate using a patented stainless steel
locking mechanism. Add-on utility modules provide electrical pass-through of, DeviceNet™, Ethernet,
PROFINET™ or PROFIBUS™ bus network signals, high current and servo signals, as well as air, vacuum,
and uid pass-through.
Tool Changers can be equipped with sensors to detect when the Tool Changer is in the locked/unlocked
positions and if the Tool plate is present. Some models require an optional Sensor Interface Plate (SIP) plate
to mount the lock and unlock sensors. If required, the use of a SIP is highly recommended for achieving the
highest level of safety and reliability.
The ATI Tool Changer has been designed to provide extremely long life with little maintenance.
3.1.1 Manually Actuated
ATI’s Manual Tool Changers provide a cost effective solution for quickly changing tools by hand.
They feature a unique design that combines high strength, excellent repeatability and a lever or
screw-cam locking mechanism with multiple fail-safe features, which resists vibration and prevents
loosening. The Manual Tool Changers also feature quick-action locking for manual operation.
These robust and compact Manual Tool Changers can handle payloads up to 80 pounds (36 kg) as
well as pass pneumatics and electrical signals.
3.1.2 Quick-Change (Round Body style)
The Quick-Change robotic Tool Changer has been designed to incorporate high strength in a small,
low-weight package. The Tool change system consists of two primary parts: the Master plate and
the Tool plate. The Master plate is mounted to a robot while the customer supplied end-effector
is typically attached to the Tool plate. The Master plate is typically mounted to the robot with an
optional interface plate. Many models have integrated pass-through air ports.
3.1.3 Heavy Automation
The Heavy Automation Robotic Tool Changer line has been developed for resistance welding and
medium-duty to heavy-duty material handling. Because a Tool Changer uses specic modules
to pass utilities such as uids, electrical, and pneumatics, it can be custom congured to handle
numerous applications.
3.2 Utility Couplers
The Utility Coupler from ATI was developed for heavy-duty, automated industrial applications where there
is a need to change tools that pass utilities such as air and electrical signals. Unlike other traditional manual
methods of connecting multiple lines, the ATI Utility Coupler is especially congured for coupling lines and
restoring operations more quickly. The modular body design is capable of mounting any of ATI’s standard
add-on utility modules and is designed to improve cycle time as well as add exibility to any production
cell. The Master-side connection can feature an unique compliance mechanism that allows for large tooling
misalignments. The Utility Coupler can be provided with an ATI locking mechanism or a drive cylinder.

2. Installation
All fasteners used to mount the Tool Changer to the robot and to customer’s tooling should be tightened to a
torque value as indicated. Refer to Table 2.1. Furthermore, removable (blue) Loctite 242 must be used on these
fasteners. Table 2.1 contains recommended values based on the engineering standards.
WARNING: Do not perform maintenance or repair(s) on the Tool Changer or modules unless
the Tool is safely supported or placed in the tool stand, all energized circuits (e.g. electrical,
air, water, etc.) are turned off, pressurized connections are purged and power is discharged
from the circuits in accordance with the customer’s safety practices and policies. Injury or
equipment damage can occur with the Tool not placed and energized circuits on. Place the
Tool in the tool stand, turn off and discharge all energized circuits, purge all pressurized
connections, and verify all circuits are de-energized before performing maintenance or
repair(s) on the Tool Changer or modules.
WARNING: Do not use lock washers under the head of the mounting fasteners or allow the
mounting fasteners to protrude above the mating surfaces of the Master and Tool plates. That
allow fasteners to protrude above the mating surface will create a gap between the Master
and Tool plates and not allow the locking mechanism to fully engage, this can cause damage
to equipment or personal injury. The mounting fasteners must be ush or below the mating
surfaces of the Master and Tool plates.
Mating Surface
Head of Mounting Fastener Must Be Flush or
Below Mating Surface. (Do Not Use Lock
Washer under Head of Mounting Fastener.)
CAUTION: Do not use fasteners with pre-applied adhesive more than once. Fasteners might
become loose and cause equipment damage. Always apply new thread locker when reusing
fasteners.
CAUTION: Do not use fasteners that exceed the thread depth in the Tool Changer. Refer to
Section 8—Drawings for details on the mounting hole thread depth. Secure the Tool Changer
with the proper length fasteners. This is true for both robot and tool interfaces.
Document #9620-20-B-210 Series Base Tool Changer-26
2.1 Master Interface
The Master plate is typically attached to the robot arm. An interface plate can adapt the Master plate to a
specic robot arm. Alignment features (dowel holes and bosses) accurately position and bolt holes secure
the Master plate to the robot arm or an interface plate. Custom interface plates are available from ATI upon
request. (Refer to the Drawing Section for technical information on the mounting features.)
CAUTION: Do not use more than two alignment features when that secure a Master
plate to an interface plate. Using more than two alignment features can cause damage
to equipment. Use either two dowel pins or a single dowel pin along with a boss/recess
feature to align the Master plate with the interface plate.
CAUTION: Do not use dowel pins that are too long or do not allow the interface plate
and Master body to mate ush. Using dowel pins that are too long will cause a gap
between the interface plate and Master body and damage to the equipment. Use dowel
pins that will not extend further than allowed by the Master body.

If the customer chooses to design and build an interface plate, consider the following points:
•The interface plate should include bolt holes for mounting and either two dowel pins or a dowel pin
and a boss for accurate positioning on the robot and Master plate. The dowel and boss features prevent
unwanted rotation. Refer to the robot manual for robot mounting features.
•The thickness of the interface plate must be sufcient to provide the necessary thread engagement for
the mounting bolts.
•Dowel pins must not extend out from the surface of the interface plate farther than the depth of the
dowel holes in the Master plate.
•If a boss is used on the Master plate, a recess of proper depth and diameter must be machined into the
interface plate to correspond with the boss on the Master plate.
•Mounting bolts that are too long can create a gap between the interface plate and the Master plate,
which can damage equipment.
•The interface plate must provide rigid mounting to the Master plate.
•The interface plate design must account for clearances required for Tool Changer module attachments

•The thickness of the interface plate must be sufcient to provide the necessary thread engagement for
the mounting bolts. Fasteners should meet minimum recommended engagement lengths while not
exceeding the maximum available thread depth. Use of bolts that are too long can cause damage to the
tool side changer.
•The plate design must account for clearances required for Tool Changer module attachments and
accessories.
•If a boss is to be used on the interface plate, a boss of proper height and diameter must be machined
into the interface plate to correspond with the recess in the Tool plate.
•The interface plate must have a hole in its center for manually returning the locking mechanism to
the unlocked position under adverse conditions (i.e. unintended loss of power and/or air pressure).
The center access hole with a minimum diameter of the 1” (25.4 mm) prevents debris from the
contaminating the locking mechanism. Greater protection is provided by leaving the race cover and
grommet in place.

Manual, Robotic Tool Changer, QC-210
Document #9620-20-B-210 Series Base Tool Changer-26
2.7 Pneumatic Requirements
Proper operation of the locking mechanism requires a constant supply of the clean, dry, non-lubricated air,
with the following conditions:
•Pressure range of the 60 to 100 psi (4.1 - 6.9 bar) Suggested 80 psi.
•Filtered minimum: 40 microns.
To lock or unlock the Tool Changer, a constant supply of the compressed air is required. If there is a loss of
air pressure in the locked state, the cam prole prevents the master plate and tool plate from unlocking, and
the Tool Changer goes into the fail-safe condition.
CAUTION: Do not use the Tool Changer in a fail-safe condition. Damage to the locking
mechanism can occur. Re-establish air pressure and ensure the Tool Changer is in a
secure lock position before returning to normal operations.
2.7.1 Valve Requirements for Air Adapter Modules
NOTICE: No valve is required when using a valve adapter module. The valve adapter
module has an integrated solenoid valve and only requires the customer to supply a
single air source to the valve adapter.
A customer supplied 2-position 4-way or 5-way valve must be used to actuate the locking
mechanism in the Master plate. It is imperative that when air is supplied to the Lock or Unlock Port
on the Master plate, that the opposite port be vented to atmosphere (i.e., when air is supplied to the
Lock Port, the Unlock Port must be open to the atmosphere.) Failure to vent trapped air or vacuum
on the inactive port may inhibit operation of the valve and prevent coupling or uncoupling.
Air Adapter without
integrated valve
CAUTION: The locking mechanism will not function properly when connected
to a 3-way valve as this type of valve is incapable of venting trapped air or
vacuum from the within the Tool Changer. This could result in damage to the
product, attached tooling, or injury to personnel. Connect the Lock and Unlock
supply air to a 2-position 4-way or 5-way valve.
Document #9620-20-B-210 Series Base Tool Changer-26
2.8 Electrical Connections
The Tool Changer is available with integrated lock/unlock sensors. If the sensors are not used, plugs are
provided to seal the locking mechanism. If a control/signal module is to be utilized on Flat ‘A’ when
ordered, the sensors will be connected to the module prior to shipping.

3. Operation
The Master plate locking mechanism is pneumatically driven to couple and uncouple with the Tool plate bearing
race.
CAUTION: Operation of the Tool Changer is dependent on the maintaining an air pressure
of 60 to 100 psi (4.1 - 6.9 bar). Damage to the locking mechanism could occur.Robot motion
must be halted If the air supply pressure drops below 60 psi (4.1 bar).
NOTICE: All Tool Changers are lubricated prior to shipment. The customer must apply additional
lubricant to the locking mechanism components and alignment pins prior to operation. Tubes of
lubricant for this purpose are shipped with every Tool Changer. Standard Tool Changers require
MobilGrease XHP222 Special (a NLGI #2 lithium complex grease with molybdenum disulde). For
custom applications, such as food grade or surgical applications, specialized lubricants might be
required.
Coupling should occur with the Master plate in the No-Touch™ locking zone. As coupling occurs, the Master plate
should pull the Tool plate into the locked position.
Program the robot to minimize misalignment during coupling and uncoupling. Greater offsets can be
accommodated by the Master and Tool plates but will increase wear. Misalignments can be caused by improper tool
stand design. Refer to Tool Storage Considerations section.

3.1 Conditions for Coupling
The following conditions should be considered when operating the Tool Changer. For more details about
programming the robot, refer to the Operation section of the Control/Signal Module Manual.
CAUTION: Do not attempt to couple the Tool Changer when in the locked position. The
locking mechanism must be in the unlock position when attempting to couple the Tool
Changer. Failure to adhere to this condition may result in damage to the unit and/or the
robot. Always unlock the Master prior to coupling to a Tool.
1. Unlock the Tool Changer by removing air pressure from the lock port and supplying air pressure to the
unlock port (If equipped, the unlock sensor indicates the Tool Changer is unlocked).
NOTICE: For Tool Changers with a control/signal module and air/valve adapters with a double
solenoid valve, turn the Unlatch output on and turn the Latch output OFF. For Tool Changers
with a control/signal module and air/valve adapters with a single solenoid valve, turn the Unlatch
output ON. Some control/signal modules prevent the Tool Changer from being unlocked unless
the Master and Tool are coupled and nested properly in the tool stand, a manual override
procedure is required to unlock the Tool Changer. Refer to your Control/Signal Module Manual
for instructions.
2. Position Master above the Tool and move the Master into ready to lock position. The mating surfaces of
the Master and Tool should be parallel and not touching. Make sure that the tapered alignment pins from
the Master enter the alignment holes on the Tool. The alignment pins should be relatively concentric with
the alignment bushings with no contact between the two.
3. It is recommended that the mating faces of the Master and Tool not be touching but be within the NoTouch distance of each other when coupling to minimize stress and wear on the locking mechanism. The
locking mechanism allows the Master to “pull up” the Tool with gaps between the two sides.
CAUTION: Direct contact of the Master and Tool mating surfaces is not suggested
or required just prior to coupling. Contact may result in damage to the unit and/or the
robot. No-Touch locking technology allows the unit to couple with a separation distance
between the Master and Tool.
4. The RTL (Ready-To-Lock) sensor and target that are built into the Tool Changer must be positioned
within approximately 0.05” (1.5 mm) of each other for the sensors to detect Tool presence. RTL signals
are not required to couple the Tool Changer but are recommended as a conrmation of the coupling prior
to removing the Tool from the tool stand.
NOTICE: At this point, communication is initiated with the ATI Tool and downstream nodes. If
equipped, Tool-ID and communications become available. Depending on the type of control/
signal module, additional notications such as RTLV, TSRV, TSIV, Tool Present, Unlatch
Enabled, and other notications can provide verication of the properly functioning system
components.
5. Couple the Tool Changer by releasing the air pressure from the unlock port and supplying air pressure
to the lock port. Air must be maintained on the lock port during operation to assure rigid coupling (If
equipped, the lock sensor indicates the Tool Changer is in the locked position).
NOTICE: For Tool Changers with a control/signal module and air/valve adapters with a double
solenoid valve, turn the Unlatch output OFF and turn the Latch output ON. For Tool Changers
with a control/signal module and air/valve adapters with a single solenoid valve, turn the Unlatch
output OFF.
Manual, Robotic Tool Changer, QC-210
Document #9620-20-B-210 Series Base Tool Changer-26
6. A sufcient delay must be programmed between locking valve actuation and robot motion so that the
locking process is complete before moving the robot. If equipped with Lock and Unlock sensors, the
Lock signal should read “ON” (true) and the Unlock signal should read “OFF” (false).
NOTICE: If the locking mechanism has been actuated and both the Lock and Unlock signals are
OFF, then a “missed tool” condition has occurred (for example, the Tool is not in the stand or is
not positioned properly). in this case an error should be generated and the robot program halted. The situation requires manual inspection to determine the cause of the problem. Some
congurations will require a manual unlock of the Master plate before attempting coupling, refer
to the Control/Signal Module Manual for instructions.
NOTICE: The locking mechanism must be in the unlock state before another attempt is made to
couple or damage could occur to the robot and/or the Tool Changer.
3.2 Fail-Safe Operation
A fail-safe condition occurs when there is an unintended loss of lock air pressure to the Master plate. When
air pressure is lost, the Tool Changer relaxes and there may be a slight separation between the Master and
Tool plates. The lock sensor may indicate that the unit is not locked. ATI’s patented fail-safe feature utilizes
a multi-tapered cam to trap the ball bearings and prevent an unintended release of the Tool plate. Positional
accuracy of the tooling is not maintained during this fail-safe condition. Do not operate the Tool Changer
in the fail-safe condition. If the source air is lost to the unit, movement should be halted until air pressure is
restored.
After air pressure is re-established to the Master plate, the locking mechanism will energize and securely
lock the Master and Tool plates together. in some cases when the load on the tool changer is signicantly off
center, it may be necessary to position load underneath the tool changer or return the tool to the tool storage
location to ensure a secure lock condition. If equipped, make sure the lock sensor indicates the Tool Changer
is in the locked position before resuming normal operations. Consult your Control/Signal Module Manual
for specic error recovery information.
CAUTION: Do not use the Tool Changer in a fail-safe condition. Damage to the locking
mechanism could occur. Re-establish air pressure and ensure the Tool Changer is in a
secure lock position before returning to normal operations.

3.3 Conditions for Uncoupling
Refer to your Air/Valve Adapter and/or Control/Signal Module Manual’s Operation section for operation
during coupling/uncoupling.
1. Move the robot to position Tool plate in the tool stand. The position for coupling and uncoupling are the
same.
NOTICE: Depending on the type of control/signal module, additional notications such as
TSRV, TSIV, and other notications can provide verication of the properly functioning system
components.
2. Unlock the Tool Changer by releasing the air pressure from the lock port and supplying air pressure to
the unlock port. The Tool Changer locking mechanism moves to the unlocked position and the Tool plate
releases from the Master plate. (If equipped, the unlock sensor indicates the Tool Changer is unlocked).
NOTICE: For Tool Changers with a control/signal module and air/valve adapters with a double
solenoid valve, turn the Unlatch output on and turn the Latch output OFF. For Tool Changers
with a control/signal module and air/valve adapters with a single solenoid valve, turn the Unlatch
output ON.
CAUTION: This Tool Changer may be equipped with a tool stand Interlock (TSI)
feature that physically breaks the Unlatch solenoid circuit. Proper Use of TSI prevents
unwanted Unlock software commands from being recognized until the circuit is made.
Make sure the Tool Changer is positioned properly to tinterface plate actuate the TSI
switch when the Tool is in the tool stand.
3. A sufcient delay must be programmed between unlocking valve actuation and robot motion so that
unlocking process is complete before moving the robot. If equipped with lock and unlock sensors,
the Unlock signal should read “on” (true) and the Lock signal should read “off” (false). Any other condition indicates a problem and the robot program should be halted. Once the Lock and Unlock
signals in the proper state, the Master plate may be moved away from the Tool plate in the axial
direction.
The robot and Master plate can now proceed to another Tool plate for coupling and subsequent operations.
3.4 ToolIdentication
When using multiple Tools, it is good practice to implement a Tool-ID system that identies each Tool with
an unique code. Tool-ID can be used to verify that the robot has picked up the proper Tool. Modules with
Tool-ID are available from ATI, refer to our Web site http://www.ati-ia.com/products/toolchanger/tool_
changer_modules.aspx for products available or contact ATI for assistance.
Manual, Robotic Tool Changer, QC-210
Document #9620-20-B-210 Series Base Tool Changer-26
3.5 Tool Storage Considerations
NOTICE: Tool stand design is critical to the operation of the Tool Changer. Improperly designed
tool stands can cause jamming and excessive wear of the Tool Changer components.
Tool plates with customer tooling attached may be stored in a tool stand. ATI provides compatible tool
stands designed for durability, longevity, and maximum adaptability to t most customers’ applications. The
ATI TSL (Tool Stand Large) system is compatible with ATI Tool Changer sizes QC-150 and larger. The TSL
systems can be equipped with horizontal modules, clamp modules, and different types of tool sensing. Visit
the ATI Web Site http://www.ati-ia.com/products/toolchanger/toolstand/large/LargeStand.aspx for products
available or contact ATI for assistance.
If the customer is supplying the tool stand, it must provide a xed, repeatable, level, and stable position
for tool pick-up and drop-off. The tool stand must support the weight of the Tool Changer Tool plate, tool
interface plate, optional modules, cables, hoses, and customer tooling without that allow deection in the
excess of the offsets specied.
Ideally, the Tool should be hanging vertically in the tool stand so that gravity assists to uncouple the Tool
plate from the Master plate during unlocking. It is possible to design tool stands that hold tools in the
horizontal position, but the necessary compliance must be provided during coupling and uncoupling. in
general, “horizontal-position” tool stands cause more wear on the locking mechanism and locating features
of the Tool Changer and tool stand.
A variety of the methods may be used to position Tool in the tool stand. A common method is to use tapered
alignment pins and bushings. Robot programming and positional repeatability are vital in the Tool pick-up
and drop-off.
A sensor that detects the presence of the Tool in the tool stand is recommended. The sensor may be used
prior to coupling to ensure the Tool is seated in the stand. Sensors may also be used as the robot starts to
move away after uncoupling. Sensors provide a safety measure If a Tool becomes jammed in the stand or if
the Tool fails to release from the robot.
Proximity sensors should be positioned so that the sensing face is vertical to prevent metal shavings, weld
spatter, or other debris from the falling on the sensor and creating false readings.
Tool stands debris shields can cover Tools and modules to protect them in the dirty environments, such as
grinding or welding. Alternatively, positioning tool stands in the areas shielded from the weld spatter, uids,
adhesives, or other debris would eliminate the need for debris shields.

2.7 Pneumatic Connections
The air supply used for coupling and uncoupling the Tool Changer should be clean, dry, and non-lubricated.
A supply pressure in the range of 60 to 100 psi is acceptable for operation of the locking mechanism, with a
setting of 80 psi suggested. The air should be ltered 40 micron or better.
CAUTION: Do not use the Tool Changer in a fail-safe condition. Do not transport the
Tool Changer in a fail-safe condition. Possible damage to the locking mechanism could
occur. Re-establish air pressure to Tool Changer before returning to normal operations.
2.7.1 Valve Requirements and Connections for the Locking Mechanism
When an air adapter is utilized that does not contain an integrated solenoid valve, it is required that
a customer supplied 2-position 4-way or 5-way valve be used to actuate the locking mechanism
in the Master plate. It is imperative that when air is supplied to the Lock or Unlock Port on the
Master plate, that the opposite port be vented to atmosphere (i.e., when air is supplied to the Lock
Port, the Unlock Port must be open to the atmosphere.) Failure to vent trapped air or vacuum on the
inactive port may inhibit proper shuttling of the valve and prevent coupling and/or uncoupling from
occurring.
CAUTION: The locking mechanism will not function properly when connected
to a 3-way valve as this type of valve is incapable of venting trapped air
pressure from within the Tool Changer. This could result in damage to the
product, attached tooling, or personnel. Connect the Lock and Unlock supply
air to a 2-position 4-way or 5-way valve.
Manual, Air Adapters
Document #9620-20-C-Jxx Air Adapters-02
3. Operation
It is important that the air adapter be supplied with clean, dry, non-lubricated air supplied between 60 and 100 psi
(4.5–6.9 Bar) and ltered at 40 microns or better. The Tool Changer is operated by supplying air to the lock port or
the air adapter to lock the Tool Changer. The Lock air must be maintained during operation and the unlock air must
be vented to the atmosphere using a 2-position 4-way or 5-way valve, refer to Section 2.7—Pneumatic Connections
for more information. To Unlock the Tool Changer air must be supplied to the unlock port on the air adapter and the
lock air must be vented to the atmosphere.
4. Maintenance
Air adapters should require no maintenance. There are no wear components, the sensor connections should be
inspected for looseness and tighten if necessary. Pneumatic connection should be inspected for leaks or damage to
hoses.
WARNING:Do not perform maintenance or repair on Tool Changer or modules unless the
Tool is safely supported or docked in the tool stand, all energized circuits (e.g. electrical,
air, water, etc.) are turned off, pressurized connections purged and power discharged from
circuits in accordance with the customer’s safety practices and policies. Injury or equipment
damage can occur with Tool not docked and energized circuits on. Dock the Tool safely in the
tool stand, turn off and discharge all energized circuits, purge all pressurized connections,
verify all energized circuits are de-energized before performing maintenance or repair on Tool
Changer or modules.

C. Control and Signal Modules
SA2—Control Module
SA3—Control Module (Potted version)
1. Product Overview
The control modules are required to provide a means for the customer to communicate with and control the Tool
Changer.
MS-style connectors allow interfacing on the Master and Tool modules. When the Tool Changer is coupled, the
Master and Tool modules communicate across their interface using a spring-loaded pin block. A exible boot
surrounds the pin block to seal the connection. This seal is water resistant but not waterproof. Several module
congurations are available to provide the customer with Tool Changer I/O and various pass-through signal
capabilities. Refer to Section7—Specications for the details of each available module.
The Tool-ID feature allows the customer to distinguish between the different tools being coupled by the Tool
Changer. The customer may set the Tool-ID by using push button switches on the Tool modules. Refer to

3.2 Recommended Sequence of Operations
This recommended sequence of operations procedure is a general guide when programming a robot or PLC
for use with a Tool Changer and a control/signal module. This procedure is intended for “automatic” modes
used during normal application processes.
1. Start→ The robot and Tool Changer Master are free of the stand or storage location, the
Tool Changer is uncoupled and the Tool Changer locking mechanism may be fully retracted
(unlocked condition) or fully extended (missed Tool condition, i.e., Locked and Unlocked inputs
are false). The Tool is by itself in the Tool Stand.
a. The RTL1 and RTL2 inputs are OFF.
b. The ATI Tool and any downstream device(s) are ofine.
2. Ensure the Master is Unlocked. (The Master must be unlocked prior to entering the Tool to
prevent the ball bearings from impinging on the Tool bearing race.)
a. A pneumatic air source is sent to the “unlock” port of the Tool Changer.
b. The “lock” port of the Tool Changer should be properly exhausted.
c. The Unlocked input goes ON and remains ON, indicating that the Tool Changer locking
mechanism is fully retracted and the unlock operation is complete.
3. Robot and Master move parallel towards the Tool and are within 0.06” of the Tool (i.e., the
module contact pins are touching, the RTL sensors have sensed the targets on the Tool).
a. ‘Input’ power connections become available on the Tool.
b. The RTL1 and RTL2 inputs are ON, indicating that it is okay to couple the Tool.
c. Communications with downstream device(s) should now be established.
4. Couple the Tool Changer.
a. A pneumatic air source is sent to the “lock” port of the Tool Changer.
b. The “unlock” port of the Tool Changer should be properly exhausted.
c. The Unlocked input goes OFF a short time later, indicating piston travel. Subsequently,
the Locked input goes ON and remains ON, indicating that the coupling operation is
complete.

5. Robot moves away from the tool stand with the Tool Changer coupled.
6. Normal operation:
a. The following inputs are ON:
i. Locked
ii. RTL1
iii. RTL2
b. The following inputs are OFF:
i. Unlocked
7. Robot moves into the tool stand with the Tool Changer coupled.
8. Uncouple the Tool Changer. IMPORTANT: It is critical that the Tool be nested securely in
the tool stand prior to uncoupling the Tool Changer.
a. A pneumatic air source is sent to the “unlock” port of the Tool Changer.
b. The “lock” port of the Tool Changer should be properly exhausted.
c. The Locked input goes OFF a short time later and subsequently the Unlocked input goes
ON and remains ON, indicating that the uncoupling operation is complete.
9. Robot and Master move up and away and are at a distance greater than 0.125” from the Tool
(the module contact pins are no longer touching).
a. The RTL1 and RTL2 inputs go OFF.
b. ‘Input’ power connections become unavailable on the Tool.
c. Communications with downstream device(s) should now be lost.

4. Maintenance
Once installed, the operation of the control modules are generally trouble free. The modules are not designed to be
eld serviced as all point-to-point wiring connections are soldered. Component replacement is limited to the V-ring
seal on the Master.
DANGER: This module has a voltage of 50 V or greater; NO contact should be attempted
before removing power. This especially includes separation or insertion of the mating
connectors or any contact with the Tool Changer, Utility Coupler, or its components. Arcing
and damage will occur if this is not observed. Remove power before attaching, disconnecting
any cables or attempting any maintenance of Tool Changer or Utility Coupler.
WARNING: Do not perform maintenance or repair on Tool Changer or modules unless the
Tool is safely supported or placed in the tool stand, all energized circuits (e.g. electrical,
air, water, etc.) are turned off, pressurized connections purged and power discharged from
circuits in accordance with the customer’s safety practices and policies. Injury or equipment
damage can occur with Tool not placed and energized circuits on. Place the Tool safely in the
tool stand, turn off and discharge all energized circuits, purge all pressurized connections,
verify all energized circuits are de-energized before performing maintenance or repair on Tool
Changer or modules.
If the Tool Changer is being used in dirty environments (e.g., welding or deburring applications), care should be
taken to limit the exposure of the Tool Changer. Idle Tool assemblies should be covered to prevent debris from
settling on the mating surface. Also, the Master assembly should be exposed for only a short period of time during
Tool change and down time.
Under normal conditions, no special maintenance is necessary; however, it is recommended that periodic
inspections be performed to assure long-lasting performance and verify that unexpected damage has not occurred.
Perform the following visual inspection monthly:
• Inspect mounting fasteners to verify they are tight and if loose; then tighten to the proper torque. Refer to
Section2—Installation.
• Cable connections should be inspected during maintenance periods to ensure they are secure. Loose
connections should be cleaned and re-tightened as appropriate. Inspect cable sheathing for damage, repair or
replace damaged cabling. Loose connections or damaged cabling are not expected and may indicate improper
routing and/or strain relieving.
• Inspect the Master and Tool pin blocks for any pin damage, debris or darkened pins. Refer to Section4.1—Pin
BlockInspectionandCleaning.
• Inspect V-ring seals for wear, abrasion, and cuts. If worn or damaged, replace. Refer to Section5.2.1—Seal
1. For a Tool Changer, if the Tool Changer is installed place the Tool safely in the tool stand. Uncouple the
Tool Changer or Utility Coupler to allow clear access to the Master and Tool plates.
2. Turn off and de-energize all energized circuits (e.g. electrical, air, water, etc.).
