Explanation
For the reaction time of the sensor (S), see the documentation of the sensor.
Transmission duration from signal acquisition at the input terminal (IN) to the logic of the
MSS 3RK3; depending on the signal
For the reaction time of the logic of the MSS 3RK3, see Chapter "Reaction time of the logic
(in error-free operation) (Page 172)"
For the fault reaction time of the logic of the MSS 3RK3, see Chapters "Fault reaction time
of the logic (single-channel actuator circuit) (Page 173)" and "Fault reaction time of the
logic (two-channel actuator circuit) (Page 173)"
Input delay for monitoring functions and input cells at the inputs
Timer functions in the logic (timer)
Transmission duration from the logic of the MSS 3RK3 to the output terminal (Q); de‐
pending on the signal; for values, see the graphic above
For the reaction of the actuator (A) including the time until the signal has been received
and processed by the actuator, see the actuator documentation
