10.11.1 Timer function for a digital input
Activation delay
The activation delay (T1) is the time between the digital signal and
the activation of the selected function.
Range: 0-6000 seconds.
Duration time
Available modes:
• Not active
• Active with interrupt
• Active without interrupt
• Active with after-run.
The duration time (T2) is the time which, together with the mode,
determines how long the selected function is active.
Range: 0 - 15,000 seconds.
