OPM-C product videos

OPM-C: panel controls and display. Timer functions and protection settings depend on the selected panel.

OPM-C: panel and enclosure view. Match the panel version, motor rating and supply.

OPM-C: control interface example. Use the supplied model guide for installation and settings.

OPM-C: base-controls example. The panel shown is OPM-C, a single-phase openwell starter.

OPM-C is designed for a compatible single phase openwell installation and combines cyclic timing and an auto switch 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 OPM-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.

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

OPM-C’s auto-switch function supports automatic operation when the configured supply and operating conditions permit it. Together with cyclic timing, this provides automatic switching and a repeated run/rest pattern. Choose the operating mode and power-return settings for your site during setup.

OPM-C’s power-on start delay provides a configured wait before starting after supply returns. The run or cyclic settings then determine the subsequent timed operation. Set the start delay and operating pattern separately for the connected pump, with electrical protection configured for the supply conditions.

OPM-C is suited to time-based pump operation where tank level is managed separately. Its timer provides the selected operating pattern, while the receiving tank remains a separate part of the pumping plan. If you want the pump to respond automatically to tank demand, compare the corresponding water-level-control options.

OPM-C offers cyclic timing and an auto switch, while OPM-T offers 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.

OPM-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

OPM-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.

Fault meanings and safe next steps

Have a qualified electrician match the single phase supply, motor rating and model wiring to the selected OPM-C variant. Set and test the timed operating pattern for the actual pump and water source. Keep the supplied diagram and agreed settings with the panel so future operation and service start from the correct model information.
