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.
2.
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
for how to
install the AC power cord into the AC power input on the computer.
DC powered models: See
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
for when power is applied to the computer for
the first time.
