*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.
*6. This is the time required for the safety input to actually switch to an activated condition after the mode selector input is
switched.

*7. Only when the G9SX-GS[] is used with manual switching.
*8. This does not include the operating time or response time of internal relays in the G9SX-EX-[].
*9. For the G9SX-[]-RT (with screw terminals) only.
