USER'S GUIDE
2-3 Safety Guard Switching Unit
Note: 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 is the allowable switching time for the operating mode selector. If switching takes more than 450 ms, the G9SX-GS@ will detect an error.
5. This is the time required for the safety input to actually switch to an activated condition after the mode selector input is switched.
6. Only when the G9SX-GS@ is used with manual switching.
7. For the G9SX-@-RT (with screw terminals) only.
