5.5 Switching mode 4
Switching mode 4 includes an RS flip-flop logic (RESET/SET logic). If 24 V is applied to input 2
(RESET) after power-up, output 2 is switched. If 24 V is also applied to input 1 (SET), output 1 is
switched and output 2 is deactivated. When the signal input 1 (SET) is cancelled again, this state
remains stable at the outputs. If the signal is now cancelled at input 2 (RESET) (0 V DC), output
1 is deactivated and output 2 is activated. This circuit state remains stable even if input 2
receives a signal again (+24 V DC). Input 2 (RESET) has priority over input 1 (SET), i. e. if input
1 has a signal (+24 V DC) and input 2 has no signal (0 V DC), output 2 is switched and output 1
is deactivated. The duration of the overexcitation pulse is set at inputs 3 and 4 (terminals 3 and
4).
