Timer signals
Timer output: The signal is active from the start until the timer elapses (high active or low active configu rable).
Tolerance band signal timer: The signal is active if the actual value before the timer start is outside the valid range.
If the actual value after the timer starts runs out of the valid range, the timer time is only stopped (timer stop signal
active) until the actual values reaches the valid range again! The tolerance band signal is not active in this case.
End signal timer: The signal is active after the timer elapses for the duration of the after-run time (or until acknow-
ledgement).
Stop signal timer: The signal is active while the timer is stopped.
Timer symbol (display)
Off: Timer is not active (function = off)
Lights up: Timer is active (function = on)
Flashes: Timer is active and running (symbol also flashes during lead time, if timer has stopped, and during after-run
time)
Behaviour after power down
The timer output signals are inactive during the device's initialization phase. The runtime and remaining running time
are saved via power off on the device. The behavior after power on is configurable.
