OPM-T: front panel and clock interface. Clock-based scheduling and timed ON/OFF operation.
Before choosing OPM-T
VUKAR OPM-T is a single phase openwell starter for 0.5–3 HP pumps.
Questions before choosing
Which controls are included?
It combines a Clock Timer, Cyclic Timer, Auto Switch, daily run-time control and motor protection for time-based pump operation. For automatic tank-level control, choose an OPA model.
What should be checked before operation?
Have a qualified electrician verify the motor rating, capacitor, protection settings, earthing and power wiring before operation.
Questions before choosing
Which pump installation is OPM-T a good fit for?
OPM-T is designed for a compatible single phase openwell installation and combines clock 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 OPM-T motor-rating option?
The listed OPM-T 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 do OPM-T’s Clock Timer and Cyclic Timer help with scheduling?
OPM-T includes both Clock Timer and Cyclic Timer functions. Clock timing supports chosen times of day, while cyclic timing supports repeated ON/OFF intervals. Decide which pattern fits your pumping plan and have the selected mode configured for that requirement.
When is OPM-T the right choice for timed pumping?
OPM-T 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.
How can I choose a useful running duration for OPM-T?
OPM-T controls pump operation by time, so choose a duration for the actual pumping conditions and water requirement. For measured litres, use a suitable water-measurement method alongside the timer; for filling to a level, choose the appropriate level-control function. Use the timer guide to decide which of those jobs your installation needs.
How should OPM-T be prepared for a scheduled run after a power cut?
OPM-T includes Clock Timer and Cyclic Timer functions for the pumping schedule. Plan the required operating times, running duration and power-on start delay, then confirm how the selected mode handles an interrupted run. Having those settings agreed during commissioning gives you a clear operating plan for unattended schedules.
How does OPM-T’s power-on delay fit into the timer setup?
OPM-T’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.
How can I use OPM-T’s saved running hours for maintenance?
OPM-T’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.
How do I choose between OPM-T and OPA-T?
OPM-T offers clock and cyclic timing, while OPA-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.
What makes a good OPM-T installation and handover?
Have a qualified electrician match the single phase supply, motor rating and model wiring to the selected OPM-T 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.
