With measurement value or signal change with latch selected (

ConF / Lim / Fnc.x = 2, 4),

the alarm relay remains set, until it was reset in the error list,
This alarm can be reset via:

di1 or

a limit value
a key combination
or via interface (

Lim1 ... Lim3 = 1).

For this, reset value 0 must be specified in the error list or via the interface. ( r page 36).

After power on or an engineering download an used input filter has an effect on the gradient of the input
signal. Therefore a valid alarm monitoring can only be processed after a certain rise up time. This time
depends on the value of the filter time constant t.F.
For t.F = 0 the monitoring results are valid immediately.
