Legend : F1: AUX C1 serves as immediate output for the time-delayed safe outputs/contacts
F2: AUX C2 serves as fault signaling
Figure 24 shows the timing diagram for Configuration Pr04.

t : Power supply activation
1
t : Safety circuit I11/I12 is closed
2
t : Output O1 and C1 are switches on immediately (reaction time)
3
t : After the parametric delay time has elapsed, output O2 and the relay contacts 17-18/27-28 switches on
4
t : Requirement of the safety function by opening the safety circuit at I11/I12
5
t : Outputs O1 and O2, relay contacts 17-18 / 27-28 and C1 switches off without any delay time
6
t : Safety circuit I11/I12 is closed
7
t : Output O1 and C1 are switches on immediately (reaction time)
8
t : After the parametrized delay time has elapsed, output O2 and the relay contacts 17-18/27-28 switches on
9
t : Power supply is switched off. All outputs and relay contacts switch off immediately
