SAFETY PRECAUTIONS

The machine is equipped with safety devices which serve to protect personnel and the machine itself from hazards arising from unforeseen accidents. However, operators must not rely exclusively on these safety devices: they must also become fully familiar with the safety guidelines presented below to ensure accidentfree operation. This instruction manual and the warning signs attached to the machine cover only those hazards which Okuma can predict. Be aware that they do not cover all possible hazards.

1. Precautions Relating to Installation

(1) Please be noted about a primary power supply as follows.

• Do not draw the primary power supply from a distribution panel that also supplies a major

noise source (for example, an electric welder or electric discharge machine) since this could cause malfunction of the CNC unit.

• If possible, connect the machine to a ground not used by any other equipment. If there is

no choice but to use a common ground, the other equipment must not generate a large amount of noise (such as an electric welder or electric discharge machine).

(2) Installation Environment

Observe the following points when installing the control enclosure.

• Make sure that the CNC unit will not be subject to direct sunlight.

• Make sure that the control enclosure will not be splashed with chips, water, or oil.

• Make sure that the control enclosure and operation panel are not subject to excessive

vibrations or shock.

• The permissible ambient temperature range for the control enclosure is 5 to 40°C.

• The permissible ambient humidity range for the control enclosure is relative humidity 50%

or less at 40°C (no condensation).

• The maximum altitude at which the control enclosure can be used is 1000 m (3281ft.).

2. Points to Check before Turning on the Power

(1) Close all the doors of the control enclosure and operation panel to prevent the entry of water,

chips, and dust.

(2) Make absolutely sure that there is nobody near the moving parts of the machine, and that there

are no obstacles around the machine, before starting machine operation.

(3) When turning on the power, turn on the main power disconnect switch first, then the CONTROL

ON switch on the operation panel.

3. Precautions Relating to Operation

(1) After turning on the power, carry out inspection and adjustment in accordance with the daily

inspection procedure described in this instruction manual.

(2) Use tools whose dimensions and type are appropriate for the work undertaken and the machine

specifications. Do not use badly worn tools since they can cause accidents.

(3) Do not, for any reason, touch the spindle or tool while spindle indexing is in progress since the

spindle could rotate: this is dangerous.

(4) Check that the workpiece and tool are properly secured.

(5) Never touch a workpiece or tool while it is rotating: this is extremely dangerous.

(6) Do not remove chips by hand while machining is in progress since this is dangerous. Always

stop the machine first, then remove the chips with a brush or broom.

(7) Do not operate the machine with any of the safety devices removed. Do not operate the

machine with any of the covers removed unless it is necessary to do so.

(8) Always stop the machine before mounting or removing a tool.

5309-E P-(ii)

SAFETY PRECAUTIONS

(9) Do not approach or touch any moving part of the machine while it is operating.

(10) Do not touch any switch or button with wet hands. This is extremely dangerous.

(11) Before using any switch or button on the operation panel, check that it is the one intended.

4. Precautions Relating to the ATC

(1) The tool clamps of the magazine, spindle, etc., are designed for reliability, but it is possible that

a tool could be released and fall in the event of an unforeseen accident, exposing you to danger: do not touch or approach the ATC mechanism during ATC operation.

(2) Always inspect and change tools in the magazine in the manual magazine interrupt mode.

(3) Remove chips adhering to the magazine at appropriate intervals since they can cause

misoperation. Do not use compressed air to remove these chips since it will only push the chips further in.

(4) If the ATC stops during operation for some reason and it has to be inspected without turning the

power off, do not touch the ATC since it may start moving suddenly.

5. On Finishing Work

(1) On finishing work, clean the vicinity of the machine.

(2) Return the ATC, APC and other equipment to the predetermined retraction position.

(3) Always turn off the power to the machine before leaving it.

(4) To turn off the power, turn off the CONTROL ON switch on the operation panel first, then the

main power disconnect switch.

5309-E P-(iii)

SAFETY PRECAUTIONS

6. Precautions during Maintenance Inspection and When Trouble Occurs

In order to prevent unforeseen accidents, damage to the machine, etc., it is essential to observe the following points when performing maintenance inspections or during checking when trouble has occurred.

(1) When trouble occurs, press the emergency stop button on the operation panel to stop the

machine.

(2) Consult the person responsible for maintenance to determine what corrective measures need

to be taken.

(3) If two or more persons must work together, establish signals so that they can communicate to

confirm safety before proceeding to each new step.

(4) Use only the specified replacement parts and fuses.

(5) Always turn the power off before starting inspection or changing parts.

(6) When parts are removed during inspection or repair work, always replace them as they were

and secure them properly with their screws, etc.

(7) When carrying out inspections in which measuring instruments are used - for example voltage

checks - make sure the instrument is properly calibrated.

(8) Do not keep combustible materials or metals inside the control enclosure or terminal box.

(9) Check that cables and wires are free of damage: damaged cables and wires will cause current

leakage and electric shocks.

(10) Maintenance inside the Control Enclosure

a. Switch the main power disconnect switch OFF before opening the control enclosure door.

b. Even when the main power disconnect switch is OFF, there may some residual charge in

the MCS drive unit (servo/spindle), and for this reason only service personnel are permitted to perform any work on this unit. Even then, they must observe the following precautions.

• MCS drive unit (servo/spindle)

The residual voltage discharges two minutes after the main switch is turned OFF.

c. The control enclosure contains the NC unit, and the NC unit has a printed circuit board

whose memory stores the machining programs, parameters, etc. In order to ensure that the contents of this memory will be retained even when the power is switched off, the memory is supplied with power by a battery. Depending on how the printed circuit boards are handled, the contents of the memory may be destroyed and for this reason only service personnel should handle these boards.

(11) Periodic Inspection of the Control Enclosure

a. Cleaning the cooling unit

The cooling unit in the door of the control enclosure serves to prevent excessive temperature rise inside the control enclosure and increase the reliability of the NC unit. Inspect the following points every three months.

• Is the fan motor inside the cooling unit working?

The motor is normal if there is a strong draft from the unit.

• Is the external air inlet blocked?

If it is blocked, clean it with compressed air.

7. General Precautions

(1) Keep the vicinity of the machine clean and tidy.

(2) Wear appropriate clothing while working, and follow the instructions of someone with sufficient

training.

(3) Make sure that your clothes and hair cannot become entangled in the machine. Machine

operators must wear safety equipment such as safety shoes and goggles.

5309-E P-(iv)

SAFETY PRECAUTIONS

(4) Machine operators must read the instruction manual carefully and make sure of the correct

procedure before operating the machine.

(5) Memorize the position of the emergency stop button so that you can press it immediately at any

time and from any position.

(6) Do not access the inside of the control panel, transformer, motor, etc., since they contain high-

voltage terminals and other components which are extremely dangerous.

(7) If two or more persons must work together, establish signals so that they can communicate to

confirm safety before proceeding to each new step.

The power is automatically shut down after the time set by "6. Automatic power shutdown timer" of MC user parameter POWER SAVE/SHUTDOWN passes away if all of the following conditions are met when this signal is turned ON in "automatic mode":

• Single block OFF in automatic operation

mode

• During existence of the machining cycle com-

pleted signal or alarm A, B or C

This signal is not affected by the automatic power shutdown effective switch ("3. 'Automatic Power Shutdown' is made effective" of MC user parameter POWER SAVE/SHUTDOWN) or automatic power shutdown ON/OFF switch. When "6. Automatic Power shutdown switch is made effective" of MC user parameter ROBOT LOADER I/F is "1", this function becomes effective only when the automatic power shutdown effective switch ("3. 'Automatic Power Shutdown' is made effective" of MC user parameter POWER SAVE/SHUTDOWN) is set to "1" or the automatic power shutdown ON/OFF switch is set to automatic power shutdown ON. When "4. Alarm is added as a requirement for Shutdown" of MC user parameter POWER SAVE/ SHUTDOWN is "0", the occurrence of an alarm A or B is not included in the automatic power shutdown conditions.
