*1.When two or more Units are connected by logical AND, the operating time and response time are the sum total of the operating times and response times, respectively, of all the Units connected by logical AND.
*2.Represents the operating time when the safety input turns ON with all other conditions set.
*3.Represents the operating time when the logical AND input turns ON with all other conditions set.
*4.This does not include the operating time or response time of Safety Guard Switching Units that are connected.
*5.This is the allowable switching time for the operating mode selector. If switching takes more than 450 ms, the G9SX-GS[] will detect an error.
