Application #2: Pump Alternation Using Relays 3 & 4 

1.  Relays 1 and 2 are set up for low and high alarm indication. 
2.  Relays 3 and 4 are set up for pump alternation.

The following graphics provide a visual representation of a typical pump 
alternation application with high and low alarm monitoring: 

 

 

Relay #4 turns the main pump on at 6000 gallons and turns it 
off at 1000 gallons. 

 

 

With the Pump Alternation feature activated, the next time the 
level reaches 6000 gallons, relay #3 transfers and starts the 
backup pump.
