7.6.9 Functional Examples of Start/
Stop Transitions
Starting an additional pump
This figure shows a possible sequence with all levels
and functions involved when a additional pump is
started by means of the pump control relays. The start-
ing of the second pump is controlled by one of the relay
outputs. The relay in this example starts the pump
directly on line. Of course other start/stop equipment
like a soft starter could be controlled by the relay out-
put.
