10.3 Hysteresis drop (4Ch)
In order to avoid an intermediate loss of the occupied signal for vehicles with a high undercarriage such as
articulated buses, trams, trucks with trailers etc, it is possible to modify the switching hystereses. An
interruption-free detection of critical vehicles is then also possible with low closure resistance setting. The
drop value threshold factory setting is 75%.
