5.167.1 Function 1: ON-delay
Selection: C04010 = "0" (Lenze setting)
• In this mode, the FB operates like a retriggerable monoflop.
Functional sequence
1. A FALSE-TRUE edge at bIn starts the internal timing element ().
2. After the delay time set via C04011 has elapsed, bOut is set to TRUE.
3. A TRUE-FALSE edge at bIn sets bOut to FALSE again. Simultaneously, the internal timing element
is reset.
5.167.2 Function 2: OFF-delay
Selection: C04010 = "1"
Functional sequence
1. A FALSE-TRUE edge at bIn sets bOut to TRUE. Simultaneously, the internal timing element () is
reset.
2. A TRUE-FALSE edge at bIn starts the internal timing element.
3. After the delay time set via C04011 has elapsed, bOut is reset to FALSE.
