TPO-H product videos

TPO-H: front panel. Water-level control with float inputs.

TPO-H: panel and float inputs. Use the supplied model guide for the selected panel and motor.

Match the motor rating and supply. Use the model wiring guide and a qualified electrician.

TPO-H is designed for a compatible three phase openwell or monoblock 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.

The listed TPO-H range is up to 10 HP, with the individual option selected for the motor nameplate. Matching HP, operating current and the three 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.

TPO-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 openwell or monoblock 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.

Use the sensor arrangement and controller connections specified for TPO-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.

TPO-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.

TPO-H’s Cyclic Timer repeats configured ON and OFF periods. This gives a repeating run/rest pattern for the openwell or monoblock pumping plan. Choose the intervals for the motor and actual water-source conditions, then configure them using the timer guidance.

Compare timer types

TPO-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 openwell or monoblock 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

TPO-H offers automatic tank-level control, cyclic timing and an inbuilt MCB, while TPO-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.

TPO-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.

Use a running-hours service record

Have a qualified electrician match the three phase supply, motor rating and model wiring to the selected TPO-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.
