XBTF024110   XBT GT touchscreen

Critical alarm indicators and system functions require independent and redundant protection
hardware and/or mechanical interlocks.
When you cycle power, wait at least 10 seconds before restoring the power to the HMI unit after it
has been turned off. Switching the power OFF and ON quickly can damage the unit.
In the event the screen can not be properly read, for example, if the backlight is not functioning, it
may be difficult or impossible to identify a function. Functions that may present a hazard if not
immediately executed, such as a fuel shut-off, must be provided independently of the unit. The
machine’s control system design must take into account the possibility of the backlight no longer
functioning and the operator being unable to control the machine or making errors in the control of
the machine.
