3.10 REPLACING THE MEMORY BACKUP BATTERY IN THE

CONTROL UNIT

Such as Offset data and system parameters are stored in SRAM in the control unit. The power for the

SRAM is backed up with a memory backup battery housed in the control unit. Therefore, the above data

is not lost even if the main power is turned off.

When the battery voltage falls, alarm message "BAT" blinks on the LCD screen and the battery alarm

signal is output to the PMC. Once the alarm message starts blinking or the alarm signal is output, replace

the battery as soon as possible. In general, the battery can be replaced within one week of the alarm first

being issued. This, however, depends on the system configuration.

If the battery voltage subsequently drops further, backup of memory can no longer be provided. Turning

on the power to the control unit in this state causes system alarm to be issued because the contents of

memory are lost. Replace the battery, clear the entire memory, then reenter the data.

For this reason, FANUC recommends that the battery be replaced once per year regardless of whether a

battery alarm is issued.

Two types of batteries are usable:

• Lithium battery incorporated in the control unit

• Commercial alkaline dry cells (R20) inserted in a battery case externally attached to the control unit

NOTE

The control unit is factory-equipped with a lithium battery by default. This battery

can provide backup for the memory contents for about a year.

3.10.1 Replacing a Lithium Battery

For LCD-mounted type control unit

Prepare a new lithium battery (ordering code: A02B-0323-K102).

<1> Turn the power to the machine (control unit) on. After about 30 seconds, turn the power off.

<2> Pull out the lithium battery on the back of the control unit. (Hold the latch of the lithium battery, and

pull the lithium battery toward you while releasing the claw from the case.)

While holding this section, pull out the battery.

<3> Mount a new lithium battery you get ready beforehand. (Push the battery until the catch is latched

with the case.) Confirm that the catch has been latched securely.

- 270 -

B-64485EN/01

3.REPLACING CONTROL UNIT MAINTENANCE PARTS

Push the battery until the

catch is latched with the

case.

WARNING

Using other than the recommended lithium battery may result in the battery

exploding. Replace the battery only with the specified lithium battery

(A02B-0323-K102).

CAUTION

Steps <1> to <3> should be completed within 30 minutes.

Do not leave the control unit without a battery for any longer than the specified

period. Otherwise, the contents of SRAM may be lost.

Before starting replacement work, save the contents of the SRAM in a batch.

Even if they are lost, they can be restored easily.

For the methods of saving all contents and restoring them, refer to the Chapter

5, “INPUT AND OUTPUT OF DATA”, and Appendix C, “BOOT SYSTEM”.

NOTE

After replacement, dispose the used battery as “industrial waste” correctly

according to the laws of the country where the machine is installed and the

ordinances of the local government having jurisdiction over the site of the

machine. When disposing the battery, insulate it, for example, by taping its

electrodes in order to prevent a short circuit.

For stand-alone type control unit

Prepare a new lithium battery (ordering code: A02B-0200-K102).

<1> Turn the power to the machine (control unit) on. After about 30 seconds, turn the power off.

<2> Remove the lithium battery on the upper section of the control unit.

First, unplug the connector by yanking the battery cable, then take the battery out of its case.

The battery case is located in the upper section of the face plate of the main board.

<3> Insert a new lithium battery and reconnect the connector.

3.10.2 Replacing a Commercial D-size Alkaline Dry Cells

Commercial alkaline dry cells (R20) can be used in place of the lithium battery incorporated in the control

unit by inserting them in a battery case externally attached to the control unit.

How to connect the battery case to the control unit

For the LCD-mounted type control unit, attach a battery cable (A02B-0323-K103) to the battery case

(A02B-0236-C282). For the stand-alone control unit, use the battery case (A02B-0236-C281), which is

factory-attached with a battery cable.

(For LCD-mounted type)

(For stand-alone type)

Example of connecting the battery case to the control unit

NOTE

1 The connector of the battery cable has a simplified lock for engagement. So, fix

the battery cable at a point within a length of 500 mm from the connector

location with no tension on it in order to prevent the connector from falling due to

its own weight or any extraneous force.

2 Keep the battery cable away from any source of noise, such as power wires.

Replacing a commercial D-size alkaline dry cells

<1> Have commercial D-size alkaline dry cells handy.

<2> Turn the power to the machine (control unit) on for about 30 seconds.

<3> Turn off the power to the control unit.

<4> Remove the cover from the battery case.

<5> Replace the old dry cells with new ones. Mount the dry cells in a correct orientation.

<6> Reinstall the cover onto the battery case.

CAUTION

Steps <1> to <6> should be completed within 30 minutes.

Do not leave the control unit without a battery for any longer than the specified

period. Otherwise, the contents of SRAM may be lost.

If steps <1> to <6> may not be completed within 30 minutes, save all contents of

the SRAM to the memory card or USB memory beforehand. Thus, if the contents

of the SRAM are lost, the contents can be restored easily.

For the methods of saving all contents and restoring them, refer to the Chapter

5, “INPUT AND OUTPUT OF DATA”, and Appendix C, “BOOT SYSTEM”.

the fan may not be able to rotate or a fan alarm may be issued even when it

rotates. After replacement, make sure that the fan rotates normally and no fan

alarm is issued.

NOTE

When a large amount of force is required to couple the fan unit with the main

unit, check if pins of the connector of the base printed circuit board are bent and

if the base printed circuit board is inserted correctly.

How to attach the protection cover

If the screen surface already has a protection cover or touch panel protection sheet attached on it, detach the

cover or sheet from it. Remove any adhesive left on it completely, using adhesive tape. Using solvent in

attempt to remove any remaining adhesive may result in the screen surface being soiled contrary to your

expectation.

Before attaching the protection cover, wipe off any soil and smear completely from the ornamental frame,

LCD surface, and soft key surface, using ethanol or diluted neutral detergent (such as kitchen detergent). If

you used neutral detergent, remove any remaining detergent, using a cloth wetted with water. Any remaining

oily substance or detergent causes the protection cover to come off easily. After making sure that the

ornamental frame is dry, follow the procedure below to attach the protection cover.

For 8.4” LCD unit

Position the protection cover in such a way that the both-side adhesive tape does not overlap with

the soft key section, LCD section, PCMCIA interface or USB port lids.

Upon completion of positioning, press the protection cover by stroking the both-side adhesive tape

section. Moving your finger along the attached surface with a short reciprocating motion can

enhance adhesion.

The protection cover surface is covered with a thin film to protect it from flaws and contamination.

Peel off the thin film from the protection cover.

Both-side adhesive tape (hatched)

For 10.4”, 12.1”, and 15” LCD units

The protection cover for the LCD units has a concave section so that it is conformable to the figure

of the display section. Position the protection cover in such a way that the concave section meets the

ornamental frame at the position indicated with the arrow while exercising care not to cause the

both-side adhesive tape to overlap with the soft key section.

Pressing the protection cover after positioning in such a way that any air left between the LCD

section and protection cover is expelled toward the right will make it possible to attach the

protection cover tidily. Once the protection cover is finally positioned, press it firmly while stroking

the both-side adhesive tape section. Moving your finger along the attached surface with a short

reciprocating motion can enhance adhesion.
