MOA-B: mode and float-input example. Check the operating mode and use the supplied model guide.
Before choosing MOA-B
Choose this model when you need automatic overhead-tank filling from a single phase monoblock (Tullu) pump. MOA-B is the base automatic Water Level Controller model in this monoblock range.
Questions before choosing
Which pump installation is MOA-B a good fit for?
MOA-B is designed for a compatible single phase monoblock (Tullu) 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.
How do I select the right MOA-B motor-rating option?
The listed MOA-B 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.
How does MOA-B help manage tank filling?
MOA-B’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 monoblock (Tullu) 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.
What is useful about MOA-B combining level control with timing?
MOA-B combines tank-demand control with cyclic timing. The level input handles tank demand, while the selected timer mode provides the timing pattern for the monoblock (Tullu) installation. Describe your desired filling and schedule together so the installer can configure the functions as one operating plan.
How should the level-sensing arrangement be prepared for MOA-B?
Use the sensor arrangement and controller connections specified for MOA-B. 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.
How can MOA-B’s dry-run restart function be set up for my water source?
MOA-B 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 monoblock (Tullu) 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 is MOA-B’s motor protection tailored to my pump?
MOA-B 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.
How can MOA-B’s display help with operation and support?
MOA-B 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.
How can I use MOA-B’s saved running hours for maintenance?
MOA-B’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 MOA-B installation and handover?
Have a qualified electrician match the single phase supply, motor rating and model wiring to the selected MOA-B 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.
