*1  Do not connect anything to these pins. 
*2  A critical error occurs if the input values from the Safety Door 1 and Safety Door 2 are 
different for two or more seconds.    They must be connected to the same switch with two 
sets of contacts. 
*3  A critical error occurs if the input values from the Emergency Stop switch contact 1 and 
Emergency Stop switch contact 2 are different for two or more seconds.  They must be 
connected the same switch with two sets of contacts.
