*2 A critical error occurs if the input values from the Safeguard 1 and Safeguard 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
