Load sensing:
The MPPW circulation pump does not have a Hall sensor to measure speed
of rotation. Instead of utilizing the Hall effect, the load is registered by
monitoring the circulation pump current consumption as follows:
During the water intake block, a certain fixed basic quantity of water is taken
into the machine. The load is sprayed with this water and some is thus
retained on items in the machine. The less water that flows back into the
sump, the larger the load because more water has been needed to wet the
individual items. The pump then has less water to circulate and its
mechanical load is reduced. By measuring current peaks, the control-power
electronic (SLT) calculates the additional quantity of water that must be taken
in to carry out the program.
