I connected a roller shutter sensor art.01825 to the input expansion module art. 01709 but it does not read the shutter movement

In the control panel parameters (on By-alarm Manager) Inputs > Special functions > Switch alarm–impulses per alarm, you can vary the number and length of the impulses (default 1 impulse, 160ms). Generally, for a roller shutter contact the settings are: from 3 to 6 impulses (check the shutter movement), 2ms.
