Water pressure sensor

The pressure sensor for static or dynamic pressure supervision must be configured at
one of the inputs H.
Due to the special requirements placed on the read in and filter algorithms, the
pressure sensor for dynamic pressure measurements must always be configured at
one of the local terminals of the LMS14... (H1/H3). Otherwise, the pressure sensor is to
be configured the same way as it is for static pressure measurements.
Plausibility check of the sensor:
If a configuration with water pressure sensor was selected, the LMS14... must read in a
valid value for the water pressure.
The kind of response to the fault depends on the check of the static water pressure.
Caution!
If all types of static pressure supervision are deactivated via the OSV function,
dynamic pressure supervision remains activated. In that case, a plausibility
check of the sensor will not be made, which means that sensor faults can no
longer be detected since the test is performed by acquiring the static pressure
values.
The water pressure sensor makes possible the following functions:
 Display of water pressure
 Triggering start prevention in case of under- or overpressure
 Water filling
 Water circulation
