WARNING

The replacement described here should be performed by a

person fully trained in maintenance and safety. If the

cabinet is opened to replace the option board, take extreme

care not to touch any high-voltage area (marked with

and covered by a shock prevention cover). If the area is

uncovered, direct contact with this area will result in an

electric shock.

NOTE

Before starting the replacement, take a back-up copy of the

contents

(parameters, programs, etc.) of the SRAM

memory of the CNC. The backup copy can be used in case

the contents of the SRAM memory are lost during the

replacement.

D Replacing the battery

If a lithium battery is used, have A02B-0200-K102 (FANUC internal

code: A98L-0031-0012) handy.

(1) Turn the CNC on. About 30 seconds later, turn the CNC off.

(2) Remove the battery from the top area of the CNC unit.

Disconnect the connector first. Then, remove the battery from the

battery case.

The battery case is provided in the top area of the face plate of the main

CPU board.

(3) Replace the battery, then connect the connector.

WARNING

The incorrect mounting of the battery may cause an

explosion. Avoid using any battery other than the one

specified here (A02B-0200-K102).

CAUTION

Complete steps (1) to (3) within 30 minutes.

If the battery is left removed for a long time, the memory

would lose the contents.

If there is a danger that the replacement cannot be

completed within 30 minutes, save the whole contents of the

CMOS memory to a memory card. The contents of the

memory can be easily restored with the memory card in

case the memory loses the contents.

Discard the dead battery, observing appropriate municipal rules and

regulations. When discarding the battery, insulate the terminal with a tape

so that no short-circuit would occur.

When using commercial

D General method

Use the connector connected to the lithium battery for an external battery.

Following the battery replacement procedure described above, replace the

standard lithium battery with an external battery in a battery case

(A02B-0236-C281).

CAUTION

1

Place the battery case

(A02B-0236-C281) in such a

position that the battery can be replaced even while the

control unit is active.

2

The connector of the battery cable uses a simple lock

system. Fix the cable within an area of 50 cm from the

connector, removing tension on the cable. This is required

to prevent the connector from coming off because of the

weight of the cable or tension on the cable.

D Replacing the battery

(1) Have commercial D-size alkaline dry cells handy.

(3) Remove the lid from the battery case.

(4) Replace the old dry cells with new ones. Mount the dry cells in a

correct orientation.

(5) Replace the lid on the battery case.

CAUTION

In the power-off state, the battery should be replaced as in

the case of the lithium battery, which is descried above.

MOUNTING AND

WARNING

DEMOUNTING CARD

Only those personnel who have received approved safety

PCBS

and maintenance training may perform this replacement

work.

When opening the cabinet and replacing a card PCB, be

careful not to touch the high-voltage circuits (marked and

fitted with an insulating cover). Touching the uncovered

high-voltage circuits presents an extremely dangerous

electric shock hazard.

CAUTION

1

Before starting replacement work, back up the contents

(such as parameters and programs) of the SRAM memory

of the CNC. Otherwise, the contents of the SRAM memory

may be lost during replacement work.

2

If the SRMA data check method (parity check or ECC check)

has been changed after the replacement, a parity or ECC

alarm may occur at power-on, possibly causing damage to

the SRAM data. Back up the SRAM data before starting

replacement, and restore the data after completing the

replacement.

WARNING

DEMOUNTING DIMM

Only those personnel who have received approved safety

MODULES

and maintenance training may perform this replacement

work.

When opening the cabinet and replacing a module, be

careful not to touch the high-voltage circuits (marked and

fitted with an insulating cover). Touching the uncovered

high-voltage circuits presents an extremely dangerous

electric shock hazard.

CAUTION

Before starting replacement work, back up the contents

(such as parameters and programs) of the SRAM memory

of the CNC. Otherwise, the contents of the SRAM memory

may be lost during replacement work.

Before replacing an SRAM module, be sure to back up the

contents of the SRAM module.

Cleaning and replacing

the air filter

Procedure for cleaning and replacing the air filter

1

Before cleaning and replacing the air filter, turn off the fan power

supply.

2

Remove the filter cover, then demount the filter.

When removing the cover, press the claw placed in

the groove on both sides inward with a screwdriver.

3

Blow air against both sides of the filter to remove dust.

4

When the filter is dirty extremely, wash it with a solution of water and

neutral detergent, and rinse it with fresh water, then allow it dry

naturally.

Alternatively, replace it with a new filter (use only the specified filter).

5

Set the cleaned or new filter. Next, align the claws with the grooves,

then press them to reinstall the cover. Check that the cover is not

removed when it is pulled toward you.

heat exchanger

Fan power cable

(Unplug the connector.)

External fan unit

Mounting screw B (1 piece)

Mounting screw A (2 pieces)

Ground wire (The ground wire can be disconnected by

removing the fan mounting screws.)

Remove the two mounting screws (A) used for mounting the external fan unit, then

demount the unit by sliding it downward. Next, disconnect the fan power cable and

ground wire. Remove mounting screw (B).

D Cleaning the fan unit

Procedure for cleaning the fan unit

1

Remove any buildup of dust, dirt, and mist from the fan motor and fan

mounting case with a dry waste cloth. If dirt such as mist cannot be

removed easily, use a waste cloth moistened with a solution of water

and neutral detergent after squeezing it softly. In this case, be careful

not to allow a solution of water and neutral detergent to enter the

electric circuitry such as the rotor of the fan motor.
