WARNING

The interlock of the Safety Door must be functioning when the robot 
system is operated.    Do not operate the system under the condition that 
the switch cannot be turned ON/OFF (e.g. The tape is put around the 
switch.).    Operating the robot system when the switch is not functioning 
properly is extremely hazardous and may cause serious safety problems 
as the Safety Door input cannot fulfill its intended function.
