Motor alternation - SEQUENCER
DIN-rail control relay for the control of motor alternation to permit a balanced wear of pumps, generators, etc. when two units are installed: one works while the other unit spares.
The system is conditioned by the status of a float that inhibits the operation when there is no water.
It is possible to insert an additional pressure switch (or pressure switch for emergency) that allows to activate the pumps when a pump is not sufficient to maintain the system pressure in case of requested distribution.
In case of failure of a pump the circuit recognizes the status and allows the activation of the other pump: in this way it is always assured the water distribution.
