Before choosing BOA-H
Choose BOA-H when tank-level automation and repeat-cycle control are required together with an inbuilt MCB.
Questions before choosing
Which pump installation is BOA-H a good fit for?
BOA-H is designed for a compatible single phase borewell or openwell installation and combines automatic tank-level control, cyclic timing and an inbuilt MCB with motor protection. This makes its function package easy to match to the way you want the pump to operate. Start with the pump type and supply, then select the motor-rating option from the product details.
How do I select the right BOA-H motor-rating option?
The listed BOA-H range is 0.5–2 HP, with the individual option selected for the motor nameplate. Matching HP, operating current and the single phase supply gives the installer the right basis for wiring and protection setup. Use your motor details alongside the product options when choosing the variant.
How does BOA-H help manage tank filling?
BOA-H’s Water Level Controller uses the connected tank-level input to start and stop the pump according to demand. This is the relevant function when the borewell or openwell pump should follow the receiving tank’s level. Have the sensor position and connections checked during setup so the input corresponds to the intended low and full conditions.
How should the level-sensing arrangement be prepared for BOA-H?
Use the sensor arrangement and controller connections specified for BOA-H. Correct positioning lets the controller respond to the tank conditions you want it to detect. During commissioning, test the input response and pump operation together using the supplied model diagram.
What does the inbuilt MCB add to BOA-H?
BOA-H includes an inbuilt MCB for short-circuit protection of the panel circuit. This complements the configured overload, dry-run and voltage functions in its motor-protection package. Have the electrician check the breaker, wiring and motor settings together as part of the complete installation.
How can I use BOA-H for repeated pump runs?
BOA-H’s Cyclic Timer repeats configured ON and OFF periods. This gives a repeating run/rest pattern for the borewell or openwell pumping plan. Choose the intervals for the motor and actual water-source conditions, then configure them using the timer guidance.
How can BOA-H’s dry-run restart function be set up for my water source?
BOA-H lists a dry-run restart function with a configured delay before another attempt. That provides a planned waiting interval after a dry-run stop in the borewell or openwell installation. Choose the interval for the actual source, follow the model’s operating and reset procedure, and check water availability and the fault condition if stops recur.
How do I choose between BOA-H and BOA-T?
BOA-H offers automatic tank-level control, cyclic timing and an inbuilt MCB, while BOA-T offers automatic tank-level control with clock and cyclic timing. Compare those functions with the timed-operation, tank-filling or MCB requirement at your site. Open the related model details and match the pump application, supply and motor variant before making the choice.
How can I use BOA-H’s saved running hours for maintenance?
BOA-H’s total running hours remain saved across days and power cuts. Recording the reading at service visits lets you calculate operating hours between valid readings for the same motor and counter. Keep the model, date and work done in the service record, and use the pump manufacturer’s maintenance guidance when planning the next visit.
What makes a good BOA-H installation and handover?
Have a qualified electrician match the single phase supply, motor rating and model wiring to the selected BOA-H variant. Check the tank-level inputs and their positions, then test the filling response. Keep the supplied diagram and agreed settings with the panel so future operation and service start from the correct model information.
