One by One Auto Changeover Unit

One No. Sump and 2 No. Motors for same Sump to 1 No. OHT or 2 No. Borewells to 1 No. OHT it works.

Soft Touch Button option is provided in the unit 1 By 1 Aco Motor 1 Motor 2 options. If selected 1 By 1 Aco option Among 2No. motors existed in one No. Sump, First 1 Motor gets ON when the water in OHT comes below prefixed level & gets full and OFF. Second time when the water in OHT comes below prefixed level 2nd Motor gets ON & vice versa.

If selected Motor 1 option, only Motor 1 will get ON and OFF, & if selected Motor 2 option Motor 2 only gets ON and OFF.

For 2No. Borewell to 1No. OHT same process as above.

Features
  • Li-Mo-Con switches “OFF” the motor for the following reasons:
    • When the water reaches maximum level in the overhead tank.
    • When there is a low voltage or high voltage.
    • When the water in the sump goes below foot valve.
    • When the water stops flowing to the overhead tank.
    • When the switch is in OFF position.
  • Li-Mo-Con switches the motor ON if:
    • The water in overhead tank falls to prefixed low level i.e., below 75%, 50%, 25% as adjusted.
    • The sump is full irrespective of any levels in the overhead tank except 100%.
    • The switch is in manual position.
    • When the Motor is running and not yet full in OHT, in this stage if current goes and comes later – The Motor will get ON and fill up the OHT even though the water is above ON position in OHT.
