Touchscreen Precautions

Start the Computer

Follow these steps to start the computer.

1. Make sure any connected components with separate power supplies (such

as an external display) are turned on first.

Make sure all necessary peripheral devices are connected to the corresponding

I/O ports on the computer.

3. Install power to the power input of the computer.

AC powered models: See Connect AC Power

on page 34 for how to

install the AC power cord into the AC power input on the computer.

DC powered models: See Connect DC Power

on page 35 for how to

install DC power to the DC power input on the computer.

WARNING: If the LCD screen darkens or if the backlight is not functioning

properly, the screen may be difficult to read and use of this screen could result in

a potentially hazardous outcome. Do not use the LCD touch screen under these

circumstances.

The design of the system must take into account the possibility of the LCD screen or

LCD touch screen losing functionality and unable to be used to maintain or change

control of the system. The touch screen shall not be the single point of control of

critical functions and is not intended to replace an E-Stop.

Design of the system should follow all applicable code and good engineering

practice. Factors to consider include the following:

• The possibility of an unreadable LCD screen

• The possibility of an inoperable touch screen

• Unexpected communication errors or delays

• Operator error in the control of the system

• Proper use of E-Stops and other safety practices

The user shall provide means to achieve a safe state during anomalies and ensure

the system has adequate redundancy for critical functions.

Failure to follow these instructions can result in death, serious injury, or equipment

damage.

IMPORTANT

The following steps apply to when the computer must be manually started.

See Connect Power

on page 34 for when power is applied to the computer for

the first time.
