Setup & Operation

This volume contains information for setup and operation of the G3 series Manipulators.
Please read this volume thoroughly before setting up and operating the Manipulators.

1. Safety

Installation and transportation of robots and robotic equipment shall be performed by
qualified personnel and should conform to all national and local codes. Please read this
manual and other related manuals before installing the robot system or before connecting
cables.
Keep this manual handy for easy access at all times.

1.1 Conventions

Setup & Operation 1. Safety

1.2 Design and Installation Safety

Only trained personnel should design and install the robot system. Trained personnel are defined as those who have taken robot system training and maintenance training classes held by the manufacturer, dealer, or local representative company, or those who understand the manuals thoroughly and have the same knowledge and skill level as those who have completed the training courses. To ensure safety, a safeguard must be installed for the robot system. For details on the safeguard, refer to the Installation and Design Precautions in the Safety chapter of the EPSON RC+ User’s Guide.
The following items are safety precautions for design personnel:
Personnel who design and/or construct the robot system with this product must read the Safety chapter in the EPSON RC+ User’s Guide to understand the safety requirements before designing and/or constructing the robot system. Designing and/or constructing the robot system without understanding the safety requirements is extremely hazardous, may result in serious bodily injury and/or severe equipment damage to the robot system, and may cause serious safety problems.
WARNING
The Manipulator and the Controller must be used within the environmental conditions described in their respective manuals. This product has been designed and manufactured strictly for use in a normal indoor environment. Using the product in an environment that exceeds the specified environmental conditions may not only shorten the life cycle of the product but may also cause serious safety problems.
The robot system must be used within the installation requirements described in the manuals. Using the robot system outside of the installation requirements may not only shorten the life cycle of the product but also cause serious safety problems.
Further precautions for installation are mentioned in the chapter Setup & Operation: 3. Environments and Installation. Please read this chapter carefully to understand safe installation procedures before installing the robots and robotic equipment.
4 G3 Rev.1

1.3 Operation Safety

The following items are safety precautions for qualified Operator personnel:
Please carefully read the Safety-related Requirements in the Safety chapter of the EPSON RC+ User’s Guide before operating the robot system. Operating the robot system without understanding the safety requirements is extremely hazardous and may result in serious bodily injury and/or severe equipment damage to the robot system.
Do not enter the operating area of the Manipulator while the power to the robot system is turned ON. Entering the operating area with the power ON is extremely hazardous and may cause serious safety problems as the Manipulator may move even if it seems to be stopped.
WARNING
Before operating the robot system, make sure that no one is inside the safeguarded area. The robot system can be operated in the mode for teaching even when someone is inside the safeguarded area. The motion of the Manipulator is always in restricted (low speeds and low power) status to secure the safety of an operator. However, operating the robot system while someone is inside the safeguarded area is extremely hazardous and may result in serious safety problems in case that the Manipulator moves unexpectedly.
Setup & Operation 1. Safety
WARNING
CAUTION
Immediately press the Emergency Stop switch whenever the Manipulator moves abnormally while the robot system is operated.
To shut off power to the robot system, pull out the power plug from the power source. Be sure to connect the AC power cable to a power receptacle. DO NOT connect it directly to a factory power source.
Before performing any replacement procedure, turn OFF the Controller and related equipment, and then pull out the power plug from the power source. Performing any replacement procedure with the power ON is extremely hazardous and may result in electric shock and/or malfunction of the robot system.
Do not insert or pull out the motor connectors while the power to the robot system is turned ON. Inserting or pulling out the motor connectors with the power ON is extremely hazardous and may result in serious bodily injury as the Manipulator may move abnormally, and also may result in electric shock and/or malfunction of the robot system.
Whenever possible, only one person should operate the robot system. If it is necessary to operate the robot system with more than one person, ensure that all people involved communicate with each other as to what they are doing and take all necessary safety precautions.

Setup & Operation 1. Safety

1.4 Emergency Stop

If the Manipulator moves abnormally during operation, immediately press the Emergency
Stop switch. Stops the power supply to the motor, and the arm stops in the shortest
distance with the dynamic brake and mechanical brake.
However, avoid pressing the Emergency Stop switch unnecessarily while the Manipulator
is running normally. Otherwise, the Manipulator may hit the peripheral equipment since
the operating trajectory while the robot system stops is different from that in normal
operation.
To place the system in emergency mode during normal operation, press the Emergency
Stop switch when the Manipulator is not moving.
Refer to the Controller manual for instructions on how to wire the Emergency Stop switch
circuit.
Free running distance in emergency
The operating Manipulator cannot stop immediately after the Emergency Stop switch is
pressed.

1.5 Emergency Movement Without Drive Power

When the system is placed in emergency mode, push the arm or joint of the
Manipulator by hand as shown below:
Arm #1 .............Push the arm by hand.
Arm #2 .............Push the arm by hand.
Joint #3 ............ The joint cannot be moved up/down by hand until the
electromagnetic brake applied to the joint has been released.
Move the joint up/down while pressing the brake release button
switch.
Joint #4........... Rotate the shaft by hand.

1.6 Manipulator Labels

The following labels are attached near the locations of the Manipulator where specific
dangers exist.
Be sure to comply with descriptions and warnings on the labels to operate and maintain
the Manipulator safely.
Do not tear, damage, or remove the labels. Use meticulous care when handling those
parts or units to which the following labels are attached as well as the nearby areas:
Labels NOTE
