6.2 Checking the nozzle station sensor condition (option)

When the machine is equipped with a nozzle station (option), check the nozzle station sensor condition.

CAUTION

If a nozzle station sensor fails to detect a nozzle, the nozzle change cannot be performed correctly and the machine

operation may be interrupted due to a nozzle detection error.

Open the nozzle station shutter.

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

2. Press the [Nozzle Stn Shutter] button to

open the nozzle station shutter.

3. Press the emergency stop button and

then open the machine safety cover.

Check the detection status of the

nozzle station sensors.

Check to see if the nozzle station sensors

detect the presence or absence of nozzles.

1. Open the [Unit]-[I/O] screen.

2. From the "Input" drop-down list, select

"NZL STATION".

3. While extracting a nozzle from the nozzle

station and returning it to the same

position, check whether the

corresponding sensor detects the nozzle

correctly.

The detection status on the screen should

read "1" when the nozzle is extracted

from the nozzle station, and should read

"0" when the nozzle is in the nozzle

station.

54311-L1-10

TIP

The nozzle station position No. where a nozzle was

extracted or inserted is displayed on the lower part of

the "Input" status screen.

Clean the nozzle station.

If the nozzle detection status is different from

the actual nozzle presence status, remove

the nozzle and visually check the nozzle

setting position. If any dust or chip is found,

remove it and clean the inside of the nozzle

with the vacuum assembly.

CAUTION

If the nozzle detection status inside the nozzle station

does not become stable for a reason other than clear

reason, such as dust, etc., or if the nozzle cannot be

detected, contact YAMAHA sales representative.

Disassembly and cleaning of the nozzle station sensors

by the user will void the warranty.
