Turned on when the display unit is not connected to connector COP21A.

If this LED is turned on when the display unit is connected, it is probable that the

optical cable is broken, the display unit is not powered on, or the display unit is

faulty.

See Appendix E “LED Display” for others.

・Replacing the main board

WARNING

Only those personnel who have received approved safety and maintenance

training may perform this replacement work.

When opening the cabinet and replacing the 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

Before replacing a printed circuit board, be sure to read Section 4.11,

“CAUTIONS IN REPLACING PCB’S,” to confirm the procedure.

Before starting replacement work, back up the SRAM data of the CNC.

Otherwise, the SRAM data may be lost during replacement work. See Section

3.9, “MAINTENANCE OF STAND-ALONE TYPE UNIT”, Chapter 5, “INPUT AND

OUTPUT OF DATA” or Appendix F, “MAINTENANCE OF OPEN CNC

(BOOT-UP AND IPL)” for explanations about how to save the contents of the

SRAM memory.

Demounting procedure

(1) The structure is designed so that the main board is fastened on the control unit with the fan unit.

For this reason, when the fan unit is mounted on the control unit, the main board cannot be

demounted.

Be sure to demount and mount the main board when the fan unit is detached. For the method of

detaching the fan unit, refer to Section 3.8, “REPLACING A FAN UNIT.”

(2) Disconnect the cables other than the battery cable.

(The battery is mounted on the face plate of the

main board, so the cable is not required to be disconnected.)

(3) Pinch handles A and B for extraction.

(4) While pushing the hook of handle A down and the hook of handle B up, extract the printed circuit

board.

Mounting procedure

(1) Pinch handles A and B for extraction, then insert the board into the control unit slowly until the

board is engaged into the connector on the back panel. Confirm that the hook of each of handles A

and B is engaged with the case.

(2) Connect the disconnected cables again correctly.

REPLACING THE FUSE OF THE CONTROL UNIT

WARNING

Before starting the replacement of a fuse, remove the cause of the fuse

burn-out.

Accordingly, the replacement should be performed by a person fully trained in

maintenance and safety. If the cabinet is opened to replace the fuse, 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.

REPLACING THE BATTERY

Offset data, and system parameters are stored in SRAM in the control unit. The power to the SRAM is

backed up by a lithium battery mounted on the front panel of the control unit. The above data is not lost

even when the main battery goes dead. The backup battery is mounted on the control unit at shipping.

This battery can maintain the contents of memory for about a year.

When the voltage of the battery becomes low, alarm message "BAT" blinks on the display and the battery

alarm signal is output to the PMC. When this alarm is displayed, replace the battery as soon as possible.

In general, the battery can be replaced within one or two weeks, however, this depends on the system

configuration.

If the voltage of the battery becomes any lower, memory can no longer be backed up. Turning on the

power to the control unit in this state causes system alarm to occur because the contents of memory are

lost. Clear the entire memory and reenter data after replacing the battery.

The following two kinds of batteries can be used.

• Lithium battery built into the CNC control unit.

• Two alkaline dry cells (size D) in the external battery case.

NOTE

A lithium battery is installed as standard at the factory.

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 SRAM would lose the contents.

If there is a danger that the replacement cannot be completed within 30 minutes,

save the whole contents of the SRAM 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-size alkaline dry cells

Replacing the battery

Have commercial D-size alkaline dry cells handy.

Turn the CNC on.

Remove the lid from the battery case.

Replace the old dry cells with new ones. Mount the dry cells in a correct orientation.
