Short terminals 1,2,3. Connect common liquid level probe in terminal no. 4 which is 

placed at the bottom of the tank touching the surface. Connect the lower liquid 

level probe in terminal no. 5 (this should be ideally at the level where the pump is 

desired to run). Connect the upper liquid level probe in terminal no. 6 (this should 

be ideally at the level where the pump is desired to stop ie. Tank should be full).

 

 

Start Condition: 

If the water level in the OH tank falls below the lower liquid level 

probe, the pump starts. LCD screen displays RUN indicating pump is running.

 

Stop Condition: 

If the water level in the OH tank rises above the upper liquid level 

probe, the pump stops. LCD screen displays FULL, indicating OH tank is full.

 

 

 
 
 
 
 

(i)

 

Using 2 float switches – for pump start & stop and overflow alarm (level-2)

 

 

 
 

 
 
 
 

 

(h)

 

Using 1 float switch - for pump start & stop

 

Connect common of Float switch to terminal 1, connect NO point of Float switch 

to terminal 2. Short terminals 2,3. Kindly ensure terminals 4,5,6 are open.

 

Start condition: 

If the water level in the pit/tank rises and the float switch is in up 

position, the pump starts. LCD screen displays RUN indicating pump is running.

 

Stop condition: 

If the water level in the pit/tank decreases and the float switch in 

down position, the pump stops. LCD screen displays NO WATER, indicating there is 

no liquid level in pit/tank.

 

Connect common of Float Switch A to terminal 1, connect NO point of Float 

switch A to terminal 2. Short terminals 2,3

 

Connect common of Float Switch B to terminal 4, connect NO point of Float 

switch B to terminal 6. Kindly ensure terminal 5 is open.

 

Start condition: 

If the water level in the pit/tank rises and the float switch is in 

up position, the pump starts. LCD screen displays RUN indicating that the pump 

is running.

 

Stop condition: 

If the water level in the pit/tank decreases and the float switch 

in down position, the pump stops. LCD screen displays NO WATER, indicating 

there is no liquid level in pit/tank.

 

Alarm condition: 

If the water level in the pit/tank rises even further despite 

pump running and Float switch (Level-2) is in up position, there is an audio-visu- 

al alarm. LCD screen displays OVERFLOW indicating that liquid level in the 

pit/tank has reached Overflow level.
