DUAL PUMP CONTROLLER -LL is specifically designed for controlling a multi-tank water supply system!
How the Dual Pump Controller-LL Works….
1. Controlling Two Pumps (Working & Standby)
* It manages two water pumps.
* One pump is the main working pump, and the other is the standby pump (a backup).
2. Automatic Pump Switching (Swapping)
* The system doesn’t rely on just one pump. For every new cycle of operation, it automatically switches to the other pump.
* Why this is useful: This prevents one pump from wearing out faster than the other, making them last longer and ensuring system reliability.
3. Timed Operation (Cyclic Timer)
* The pumps are set to run(ON) for a specific time (‘ON-TIME’) and then rest(OFF) for a specific time (‘OFF-TIME’).
* You can change these times yourself to match your needs.
4. Smart Starting with Pressure Sensor
* During the pump’s programmed ‘ON-TIME’, it will only start if the water pressure in the delivery pipe is less than ‘P-ON’.
* Simple meaning of ‘P-ON’: This is the minimum pressure required. If the pressure is lower than this setting, it means water is needed in the tanks, and the pump must start working.
5. Smart Stopping when Tanks are Full
* The pump will stop running if the pressure goes above ‘P-OFF’.
* Simple meaning of ‘P-OFF’: When a tank gets full, its ball valve closes. This action causes the pressure in the whole line to immediately shoot up. When the pressure exceeds this ‘P-OFF’ setting, the controller knows the job is done and shuts the pump off.
6. Protection for DRY RUN
When the Water level in the Source tank (Sump/well, etc) goes too less and there is no water available, it stops the pump. Thereby it protects the pump from running dry without water and getting burnt.
* It uses a special magnet sensor to check if the main water source (the sump tank) is empty.
* If the sump tank is empty, the pump is immediately stopped to prevent it from running dry and getting damaged.
So, it’s a “set-and-forget” system that uses a timer, pressure sensors, and a sump level sensor to efficiently deliver water to multiple tanks while automatically balancing the work between two pumps.
