Using two float switches
Start condition:
If the liquid level in the pit/tank rises, ie. Float A is in up position. Panel will
start pump A. Panel will alternate between pump A and pump B after previous
cycle is completed. LCD screen will display RUN whichever pump in running.
If the liquid level in the pit/tank rises even further after first pump is running ie.
Float Switch A and Float switch B are in up position. As soon as Float switch B
reaches up position, panel will start whichever pump is in standby. E.g., If pump A
was running and liquid level rose even further and Float B comes in up position,
pump B will also start operating in parallel to pump A.
Stop condition:
If the liquid level in the pit/tank falls, i.e.. Float A is in down position. Panel will
stop whichever pump is running. This means that there is not enough water to
pump. LCD screen will display No water.
If both pumps, we're running, then both pumps will stop simultaneously when
float switch A is in down position. LCD screen will display No water.
