BOA-C is designed for a compatible single phase borewell or openwell installation and combines automatic tank-level control and cyclic timing 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.

The listed BOA-C range is 0.5–3 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.

BOA-C’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.

BOA-C combines tank-demand control with cyclic timing. The level input handles tank demand, while the selected timer mode provides the timing pattern for the borewell or openwell installation. Describe your desired filling and schedule together so the installer can configure the functions as one operating plan.

Compare timer types

Use the sensor arrangement and controller connections specified for BOA-C. 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.

BOA-C 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.

Fault meanings and safe next steps

BOA-C uses configured overload, dry-run and voltage limits for the connected motor. Matching those values to the nameplate, supply and observed operation makes protection setup specific to your installation. Have a qualified electrician set and check the values using the exact model instructions.

BOA-C displays electrical readings, timer information and fault indications. Those details help you describe the pump’s operating state clearly when discussing a setting or a stop. Record the model and displayed values, then use the fault guide to identify the next check or share the information when requesting help.

BOA-C’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.

Use a running-hours service record

Have a qualified electrician match the single phase supply, motor rating and model wiring to the selected BOA-C 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.
