Fig. 19: Alternating pump control
Alternate switching is used to ensure that several pumps are utilized evenly in level control
systems. The main factor for switching on a certain pump is not a fixed assigned switch-on
value but rather the operating time of the pumps.
In total, the first 4 relays (LIMIT 1 to 4) can be included in the alternating pump control
system.
If power is switched off, the time for the 24-hour activation function starts again.
