1. SAFETY PRECAUTIONS B-81465EN-1/05

-15-

1 SAFETY PRECAUTIONS

For the safety of the operator and the system, follow all safety precautions when operating a robot andits peripheral devices installed in a work cell.

1.1 OPERATOR SAFETY

Operator safety is the primary safety consideration. Because it is very dangerous to enter the operatingspace of the robot during automatic operation, adequate safety precautions must be observed.

The following lists the general safety precautions. Careful consideration must be made to ensureoperator safety.

1. Have the robot system operators attend the training courses held by FANUC.

2. Even when the robot is stationary, it is possible that the robot is still ready to move state and iswaiting for a signal. In this state, the robot is regarded as still in motion. To ensure operator safety,provide the system with an alarm to indicate visually or aurally that the robot is in motion.

3. Install a safety fence with a gate so that no operator can enter the work area without passing throughthe gate. Equip the gate with an interlock that stops the robot when the gate is opened.

4. Provide the peripheral devices with appropriate grounding (Class 1, Class 2, or Class 3).

5. Try to install the peripheral devices outside the work area.

6. Draw an outline on the floor, clearly indicating the range of the robot motion, including the toolssuch as a hand.

7. Install a mat switch or photoelectric switch on the floor with an interlock to a visual or aural alarmthat stops the robot when an operator enters the work area.

8. If necessary, install a safety lock so that no one except the operator in charge can turn on the powerof the robot.

FANUC provides various training courses. Contact our sales office for details.

The controller is designed to receive this interlock signal. When the gate is opened and this signal

received, the controller stops the robot in an emergency. For connection, see Fig.1.1.

The circuit breaker installed in the controller is designed to disable anyone from turning it on whenit is locked with a padlock.

1.1.1 Operator Safety

The operator is a person who operates the robot system. In this sense, a worker who operates the teachpendant is also an operator. However, this section does not apply to teach pendant operators.

1. If it is not necessary for the robot to operate, turn off the power of the robot controller or press theEMERGENCY STOP button, and then proceed with necessary work.

2. Operate the robot system at a location outside the work area.

3. Install a safety fence with a safety gate to prevent any worker other than the operator from enteringthe work area unexpectedly and also to prevent the worker from entering a dangerous area.

4. Install an EMERGENCY STOP button within the operator's reach.

Fig. 1.1.1 Connection Diagram for External Emergency Stop Switch

The robot controller is designed to be connected to an external EMERGENCY STOP button. Withthis connection, the controller stops the robot operation when the external EMERGENCY STOPbutton is pressed. See the diagram below for connection.

1 External EMERGENCY STOP button 3 Note: Connect to EES1 and EES11, EES2 and EES21.

1.1.2 Safety of the Teach Pendant Operator

While teaching the robot, it is necessary for the operator to enter the work area of the robot. It isparticularly necessary to ensure the safety of the teach pendant operator.

1. Unless it is specifically necessary to enter the robot work area, carry out all tasks outside the area.

2. Before teaching the robot, check that the robot and its peripheral devices are all in the normaloperating condition.

3. When entering the robot work area and teaching the robot, be sure to check the location andcondition of the safety devices (such as the EMERGENCY STOP button and the deadman's switchon the teach pendant).

4. The teach pendant operator should pay careful attention so that no other workers enter the robotwork area.

NOTE

The teach pendant supplied by FANUC is provided with a teach pendant enable switch and adeadman's switch in addition to the EMERGENCY STOP button. The functions of each switch areas follows.

EMERGENCY STOP button:

Pressing this button stops the robot in an emergency, irrespective to the condition of theteach pendant enable switch.

Deadman's switch:

The function depends on the state of the teach pendant enable switch.

When the enable switch is on:

Releasing the finger from the deadman switch or holding the deadman switch stronglystops the robot in an emergency.

When the enable switch is off:

The deadman's switch is ineffective.

NOTE

The deadman switch is provided so that the robot operation can be stopped simply by releasingfinger from the teach pendant or holding the deadman switch strongly in case of emergency. TheR-J3iB has adopted a 3-position deadman switch as an RIA-specification teach pendant. Pressingthe 3-position deadman switch halfway makes the robot operable. Releasing the finger from thedeadman switch or holding the deadman switch strongly causes the robot to enter the emergencystop state.

5. When entering the robot work area, the teach pendant operator should enable the teach pendantwhenever he or she enters the robot work area. In particular, while the teach pendant enable switchis off, make certain that no start command is sent to the robot from any operator's panel other thanthe teach pendant.

6. To start the system using the operator's panel/operation box, make certain that nobody is in therobot work area and that there are no abnormal conditions in the robot work area.

7. When a program is completed, be sure to carry out a test run according to the procedure below.

a. Run the program for at least one operation cycle in the single step mode at low speed.b. Run the program for at least one operation cycle in the continuous operation mode at low

speed.

c. Run the program for one operation cycle in the continuous operation mode at theintermediate speed and check that no abnormalities occur due to a delay in timing.

d. Run the program for one operation cycle in the continuous operation mode at the normaloperating speed and check that the system operates automatically without trouble.

e. After checking the completeness of the program through the test run above, execute it inthe automatic operation mode.

8. While operating the system in the automatic operation mode, the teach pendant operator shouldleave the robot work area.

NOTEIn addition to the above, the teach pendant enable switch and the deadman's switch also have thefollowing function.By pressing the deadman's switch while the enable switch is on, the emergency stop factor(normally the safety gate) connected to EAS1 and EAS11, EAS2 and EAS21 of the controller isinvalidated. In this case, it is possible for an operator to enter the fence during teach operationwithout pressing the EMERGENCY STOP button. In other words, the system understands that thecombined operations of pressing the teach pendant enable switch and pressing the deadman's switchindicates the start of teaching. The teach pendant operator should be well aware that the safety gateis not functional under this condition and bear full responsibility to ensure that no one enters thefence during teaching.

The teach pendant, operator's panel/operation box, and peripheral device interface send each robotstart signal. However the validity of each signal changes as follows depending on the mode of theteach pendant enable switch and the remote condition.

1.1.3 Safety During Maintenance

For the safety of maintenance personnel, pay utmost attention to the following.1. Except when specifically necessary, turn off the power of the controller while carrying out

maintenance. Lock the power switch, if necessary, so that no other person can turn it on.

2. When disconnecting the pneumatic system, be sure to reduce the supply pressure.

3. Before the start of teaching, check that the robot and its peripheral devices are all in the normaloperating condition.

4. If it is necessary to enter the robot work area for maintenance when the power is turned on, theworker should indicate that the machine is being serviced and make certain that no one starts therobot unexpectedly.

5. Do not operate the robot in the automatic mode while anybody is in the robot work area.

6. When it is necessary to maintain the robot alongside a wall or instrument, or when multiple workersare working nearby, make certain that their escape path is not obstructed.

7. When a tool is mounted on the robot, or when any moving device other than the robot is installed,such as belt conveyor, pay careful attention to its motion.

8. If necessary, have a worker who is familiar with the robot system stand beside the operator's paneland observe the work being performed. If any danger arises, the worker should be ready to pressthe EMERGENCY STOP button at any time.

9. When replacing or reinstalling components, take care to prevent foreign matter from entering thesystem

10.When handling each unit or printed circuit board in the controller during inspection, turn off thepower of the controller and also turn off the circuit breaker to protect against electric shock.

11.When replacing parts, be sure to use those specified by FANUC. In particular, never use fuses orother parts of non-specified ratings. They may cause a fire or result in damage to the componentsin the controller.

1.2 SAFETY OF THE TOOLS AND PERIPHERAL DEVICES

1.2.1 Precautions in Programming

1. Use a limit switch or other sensor to detect a dangerous condition and, if necessary, design theprogram to stop the robot when the sensor signal is received.

2. Design the program to stop the robot when an abnormal condition occurs in any other robots orperipheral devices, even though the robot itself is normal.

3. For a system in which the robot and its peripheral devices are insynchronous motion, particular caremust be taken in programming so that they donot interfere with each other.

4. Provide a suitable interface between the robot and its peripheral devices so that the robot can detectthe states of all devices in the system and can be stopped according to the states.

1.2.2 Precautions for Mechanism

1. Keep the component cells of the robot system clean, and operate the robot in an environment freeof grease, water, and dust.

2. Employ a limit switch or mechanical stopper to limit the robot motion so that the robot does notcome into contact with its peripheral devices or tools.

1.3 SAFETY OF THE ROBOT MECHANISM

1.3.1 Precautions in Operation

1. When operating the robot in the jog mode, set it at an appropriate speed so that the operator canmanage the robot in any eventuality.

2. Before pressing the jog key, be sure you know in advance what motion the robot will perform inthe jog mode.


1. When the work areas of robots overlap, make certain that the motions of the robots do not interfere

with each other.2. Be sure to specify the predetermined work origin in a motion program for the robot and program

the motion so that it starts from the origin and terminates at the origin. Make it possible for theoperator to easily distinguish at a glance that the robot motion has terminated.

1.3.3 Precautions for Mechanisms

1. Keep the work area of the robot clean, and operate the robot in an environment free of grease,water, and dust.

3 TROUBLESHOOTING

This chapter describes the checking method and corrective action for each error code indicated if ahardware alarm occurs. Refer to the operator's manual to release program alarms.

3.1 POWER CANNOT BE TURNED ON

Check and Corrective action Figure

(Check 1)Check that the circuit breaker is on and has not tripped.

(Corrective action)Turn on the circuit breaker.


42/565

B-81465EN-1/05 MAINTENANCE 3. TROUBLESHOOTING

-42-

(Check 2)Check whether the LED (PIL: green) on the power supply

unit is on.

(Corrective action)

If the LED is not on, 200 VAC is not supplied to the

power supply unit. It is likely that fuse F1 in the powersupply unit has blown.

- If 200 VAC is not supplied:Find the cause by referencing the general schematicdiagram presented in the appendix.

- If 200 VAC is supplied:

Find the cause of the blown fuse. Fuse F1 is in the powersupply unit. Before you start troubleshooting, turn off the

circuit breaker.

a) If fuse F1 has blown:

- See Corrective action (1).b) If fuse F1 has not blown: - Replace the power supply unit.

(Corrective action(1))Causes of blown fuses F1 and corrective action

a) Check whether the unit and printed-circuit boardconnected to the connectors CP2 and CP3 in the power

supply unit are abnormal, by referencing the generalschematic diagram presented in the appendix.

b) Short-circuit in the surge absorber VS1VS1 is inserted to absorb surge voltage between input

lines.If the surge voltage is excessive or sustained,

excessively high voltage is applied to VS1 and a failureoccurs in the short-circuit mode, causing F1 to blow. If ashort-circuit occurs in VS1, and there is not a spare part,

the system is permitted to operate without VS1. In thiscase, however, obtain and install a new VS1 as soon aspossible. VS1 ordering number:

A50L-2001-0122#G431k

c) Short-circuit of diode stack DB1

d) The secondary power supply module is faulty :If one of the causes (b) to (c) above is detected, replace

the power supply unit with a spare unit.

The spec. for F1 is : A60L-0001-0396#8.0A



43/565


-43-


(Check 3)Check whether the EXON1 and EXON2 signals, and

the EXOFF1 and EXOFF2 signals are connected onthe terminal block on the panel board.

(Corrective action)

If the external ON/OFF function is not used, connectthe EXON1 and EXON2 the EXOFF1 and EXOFF2.

If the external ON and OFF lines are already used,check the mating contacts and the cable.


44/565


-44-

(Check 4)Check whether the connector (JRS11) on the mainboard or the connector (JRS11) on the panel board is

connected properly. Another probable cause is that

the cable connected to either of these connectors is

faulty.

(Check 5)Check 1 to 3 above confirm that 200 VAC power issupplied to connector CP1 of the power supply unit

and that the ON/OFF switch functions normally.Therefore check the power supply unit using the

following procedure:If the LED (ALM: red) on the power supply unit ison

Check if the +24 V external connection cable is

connected to 0 V or ground.

a) Fuse F4 blown :

See corrective action (2).

b) None of the above fuses blown [d) is also

probable] :

A printed circuit board or unit that uses a DC supplyvoltage (+3.3V, +5V, +24V, or +/-15V) is faulty.

c) None of the above fuses blown :Check that 200 VAC is supplied to connector CP1. If

it is supplied replace the power supply unit.

(Corrective action)

If the power supply unit is not faulty, replace thepanel board or operators panel.

(Corrective action (2))

Causes of blown fuse F4 and corrective actionThe device connected to connector CP5 of the power

supply unit may be faulty. If no device is connectedto CP5 or the connected device is normal, the +24 V

power used in a printed circuit board connected to the

backplane is faulty.The code of F4 is A60L-0001-0046#7.5 :
