Remark 2:
Basic SWITCHMATIC can only detect dryrunning operation
through the minimum pressure. This means that plumber must
determine the water column of the installation, the start pressu
re of the pump and place the minimum pressure below the start
pressure.
It can also occur that pumping system is running out of its curve so
that the pump is unable to provide the minimum pressure because
the fl ow requirement is excessive. In this case SWITCHMATIC would
activate a false dryrunning alarm.
If these concepts are not clear, it is preferable not confi gure this
protection or install the SWITCHMATIC 2 with accurate and easy
setting of dryrun detection.
