Start the Computer
Follow these steps to start the computer.
1. Make sure all necessary peripheral devices are connected to the
corresponding I/O ports on the computer.
2. Make sure any connected components with separate power supplies
(such as an external display) are turned on first.
3. See
for how to install DC power to the DC
power input on the computer.
4. Apply 18…32V DC power to the computer.

for the power switch location.
The computer performs certain actions every time it is started or reset. See
for what is done.
If your computer does not start or you notice other anomalies, refer to
WARNING:
If the LCD screen darkens or if the backlight is not functioning
properly, the screen can 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.
System design must take into account that the LCD screen or LCD touch screen
can lose functionality and therefore be unable to maintain or change control of
the system. The touch screen cannot be the single point of control of critical
functions and is not intended to replace an E-stop.
System design must 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
You must provide means to achieve a safe state during anomalies and help
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 you must manually start the computer.
See
for when power is applied to the computer
for the first time.
