1.2 Replacing ionizer discharge needle (2-year)

Replace the ionizer discharge needle (KHN-M83P2-00X: Needle/one discharge needle pack) once every 2

years or if the LED (+ERR, - ERR) showing the ion balance error does not go off even after performing the work

steps stated in "1.1 Cleaning ionizer discharge needle (Monthly)". One ionizer uses 12 discharge needles.

Normally, one ionizer is installed on each of the front and rear of the machine. So, 24 discharge needles are

needed when performing the maintenance work of one machine.

Power off the ionizer.

1. The power supply to ionizer is stopped by

pressing emergency stop button and

then open the machine safety cover.

Check that all LEDs on ionizer is turned

off.

WARNING

A VOLTAGE REMAINS ON THE DISCHARGE NEEDLE

IMMEDIATELY AFTER TURNING OFF THE POWER. BE AWARE

THAT TOUCHING THE DISCHARGE NEEDLE IMMEDIATELY

AFTER TURNING OFF THE POWER IS HAZARDOUS.

Turn off the air supply.

Turn the air supply/exhaust switch (valve) on

the lower left of the machine clockwise (EXT)

to turn off the main air.

Remove the discharge needle.

As shown in the figure on the right, grasp

and squeeze the holder's opposing claws at

2 points and squeeze them toward each

other, then extract discharge needle.

Replace the discharge needle.

When installing the new discharge needle,

the notched area on the mounting side must

be aligned with the discharge needle unit's

protruding part. When correctly aligned,

press it in.

(When the charge plate monitor is

installed,) check the static

elimination performance.

1. Turn the air supply/exhaust switch (valve)

and supply the air to the machine.

2. Power on the machine.

Place a charge plate motor near the

feeder pickup position to check the

discharge performance.

NOTE

The static elimination performance standard is that the attenuation measurement time at the feeder pickup position

(a period of time to attenuate an electro static charge of +1000V to +100V or less) is 15 sec. or less.

If the static elimination performance is not recovered or if an error occurs on the ionizer side continuously even after

replacing the discharge needle, contact YAMAHA sales representatives.

NOTE

For detailed speciﬁcation of the ionizer, see the instruction manual established by the ionizer manufacturer.

2. UPS (Uninterruptible Power Supply)

2.1 Replacing UPS battery (3-year)

The battery is a consumable item. Even though the service life of the UPS may vary depending on the operating

environment, such as ambient temperature, it is recommended to replace the battery with a new one (KGA-

M6566-30X) at reference intervals of 3 years. The following describes how to replace the battery that is

incorporated into the UPS.

WARNING

BATTERY REPLACEMENTS SHOULD BE PERFORMED ONLY BY THOSE WITH ELECTRICAL WORK EXPERIENCE.

Power off the machine

Power off UPS several seconds after

powering off the machine.

WARNING

DO NOT ATTEMPT THIS BATTERY REPLACEMENT

PROCEDURE WHILE THE UPS FUNCTION IS RUNNING

(DURING AN EMERGENCY STOP, ETC.).

Detach the front panel.

Use a Phillips screwdriver to remove the

screws mounting the front panel. Then

detach the front panel.

Disconnect the battery connector.

Disconnect the UPS side and internal battery

side connectors.

Remove the battery securing

fixture.

Remove the battery fixture mounting screws,

then remove the battery securing fixture.

Replace the removed battery with a

new one.

Extract the old battery and insert a new

battery in its place.

Attach the battery.

Reverse Steps 2 to 4 above to attach the

battery.

Check the UPS status.

1. Power on the machine.

2. Press the ON button on the UPS operation

panel to check that the BATTERY LED is

OFF.

Write the battery replacement year/

month.

Write the battery replacement year/month

on the UPS WARNING label (see "Safety

instructions" in this manual).

NOTE

For UPS details, refer either to the optional manual "UPS

(Uninterruptible power supply unit)" or to the

manufacturer's operation manual.

3. Nozzle station

3.1 Checking and cleaning nozzle sensor (1-year)

When the machine is equipped with the nozzle station (option), it is necessary to periodically check the nozzle

detection sensor status.

CAUTION

If the nozzle station sensor cannot detect the nozzle correctly, the nozzle change does not operate correctly or the

production cannot continue due to nozzle detection error.

Make the preparations for work.

1. Return all nozzles to the nozzle station.

2. Press the emergency stop button and

then open the machine safety cover.

Open the shutter of the nozzle

station (hereafter "ANC").

1. Open the [Unit] - [Head] screen.

2. Press the [Nozzle. Stn Shutter] button to

open the ANC shutter.

Open the Utilities mode.

1. Press the [Utilities] button on the left of

the screen.

2. The "Login" window will appear. Check

that "Operator" is shown in the “User”

field, and then press the [OK] button.

NOTE

When logging-in to the Utilities mode with "User:
