WARNING

- In the digital I/O check procedures, touch panel buttons except for

function buttons are inoperative.

Even if, for example, you press the <Cut Water> button, the wheel

coolant supply does not shut off.

The personnel who perform the digital I/O checkout must bear this

in mind and exercise due care to ensure safety.

- In the digital I/O check procedures, the operation command for

solenoid valves and etc. can be forcibly turned ON and OFF by the

function buttons. In some cases, therefore, a cylinder may be

invoked to operate.

Ensure that no person other than the maintenance personnel

touches the machine during this procedure.

- If any touch panel control is inadvertently activated during

maintenance or inspection, unexpected machine operation may

cause death or serious injury.

While you don't use the touch panel, press the Disco's logo button

located at the upper left of the screen in order to lock up and

deactivate the touch panel.
