1.2 Replacing the 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 the ionizer discharge needle". One ionizer uses 12 discharge needles. Normally,

one ionizer is installed on each of the front and rear of the machine. So, 24 (6 sets) discharge needles are

needed when performing the maintenance work of one machine.

Power off the ionizer.

Press the emergency stop button and

open the machine safety cover to stop

the power supply to the ionizer.

2. Check all LED on the ionizer are 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.

Remove the discharge needle.

As shown at right, grasp and squeeze the

holder's opposing claws at two 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 ON the machine power.

2. Place the charge plate monitor at a

portion around the feeder pickup

position, and then check the static

elimination 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 representative.

NOTE

For detailed speciﬁcation of the ionizer, see the

instruction manual established by the ionizer

manufacturer.
