6.1.3 Automatic Error reset
If you confirm “Reset Error?” with Yes then errors for this control will be reset automatically as
soon as the sensor signals no (or again) water contact (depends on the operation mode).
This function offers a higher degree of convenience because in case of the Automatic Top
Off, an error is automatically reset as soon as the missing water is re-filled manually). It does
however, carry a higher risk since the cause of error could persist further on. Therefore we
recommend full consideration if this function is to be used.
6.1.4 Sensor select
Here, you can determine which level sensor inputs are to be used by this level control.
2 sensors are to be selected for operating modes with 2 sensors.
6.2 Input
After selecting a level sensor input, you can set its behavior. Normally these settings need
not be changed.
6.2.1 Reaction Time
Set here the Reaction time of the level sensor input. It can be set between 0s and 240s
(Standard is 1s).
This feature is useful in instances where you may want to set a level sensor reaction delay. In
areas where there is frequent water surface agitation in the same area as the sensor, the
assigned switchable socket may turn on/off too often. ProfiLux 4 monitors if the signal (=
water there/not there) transmitted by the sensor is stable. Stable means in this case that a
change of the level has to remain constant at least for the set reaction time. Only if the level
is stable, the level control reacts. The reaction time shall be set sufficiently so that waves
don’t cause an activation of the regulation, but small enough that a reached level is not
recognized too late!
The Reaction time should be set high enough so that waves do not cause a response of the
control, but also small enough so that an attained level is not detected too late!
6.2.2 Input Inverse
Under certain circumstances it may be useful to invert the switching behavior of the sensor
(for example, if the sensor can only be installed upside down). Confirm Input invert? with Yes
then the sensor input is inverted.
