WARNING
LOSS OF CONTROL
 Consider the potential failure modes of control paths in the machine control system design,
such as:
 the possibility of backlight failure,
 unanticipated link transmission delays or failures,
 the operator being unable to control the machine,
 the operator making errors in the control of the machine.
 Provide a means to achieve a safe state during and after a path failure for critical control
functions such as emergency stop and overtravel stop.
 Provide separate or redundant control paths for critical control functions.
 Test individually and thoroughly each implementation of the panel for correct operation before
service.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
