Automatic deactivation of dynamic pressure supervision at low static water
pressures:
If the static water pressure falls below a certain level, this may have an impact on the
measurement of dynamic pressures (depending on the location of the pressure sensor,
the pump, and the pressure expansion vessel in relation to the hydraulic resistances in
the system). In that case, it is possible to select automatic deactivation of dynamic
pressure supervision via parameters DynPress warn offset
[4201.1], DynPress
AutoActive
[4202.1], and Dyn PressSupAutoActive upper limit.
Automatic deactivation can be switched on/off via parameter DynPress AutoActive
[4202.1].
If the function is activated, dynamic pressure supervision is automatically deactivated if
the static pressure drops below the limit value:
Water pressure Hx < Water pressure min + DynPress warn offset [4201.1].
Dynamic pressure supervision is automatically reactivated when:
Water pressure Hx > Water pressure min + DynPress warn offset [4201.1]
Line no. Operating line
[4195.1] Dyn press supervision
[4198.1] DynPress pump delay
[4199.1] DynPress repetitions
[4200.1] Dyn Press pause
[4201.1] DynPress warn offset
[4202.1] DynPress AutoActive
Note!
The water pressure is displayed with a resolution of 1 mbar (without physical unit),
even if the sensor does not physically offer this resolution.
The resolution in mbar that can actually be measured depends on the sensor’s output
voltage range in relation to the acquired pressure range and must be clarified on a
case-to-case basis.
Due to strong filtering of the measuring signal, intermediate values of the quantization
stages may dynamically occur. For this reason, always wait until the settling state is
reached (Tdelay).
