Electronic control – from concept to implementation
Electronic control includes the measurement layer, HMI/PLC logic and communication to BMS/SCADA. In a well-designed system pump operation control is based on reliable input signals and transparent sequences. The operator sees process parameters and reads reports about current operating status even before the need for intervention arises. In practice, the naming of alarms, the readability of screens and the retracing of service activities are of great importance.
Pump motor control – state matrix, priorities, schedules
Pump motor control starts with the definition of the states: MANUAL, AUTO, SERVICE, FAILURE. In two- and multi-pump systems, rotation and reserve logic are important. Start-up schedules compensate for mechanical wear and tear, and the inverter keeps process values stable. It is worth presenting trends and descriptions of activities in reports control the operation of the pump in a repeatable manner. Thanks to this management operation of the pump motor is not limited to responding to alarms, but is an element of planned operation.
Pump motor protection – multi-layer protection
Motor protection should take into account overloads, overheating, phase loss or asymmetry, as well as the start and stop sequence. The power layer includes motor switches, thermal relays and sensors, and the logic layer includes alarm definitions and controlled turning off the pump with registration of reasons and time stopped pump. A good practice is the FAT/SAT acceptance test, in which we go through all the steps before allowing the installation to operate.
Engine controller – interface, diagnostics, reporting
The intuitive panel shows key variables: levels, pressures, flow, temperatures and alarms. Modern solutions also include remote functions and smart pumps, which provide charts, notifications and service parameters. Recovering from anomalies is made easier by secure automatic restart – allowed only after meeting safety conditions and confirming the possibility of starting.
Control and security – how they work together
Protection and control they are two elements of one process. Correctly built a set of pump protection devices reacts to deviations, and logic decides whether to perform mild ones turning off the pump, switch to reserve or maintain operation to a safe point. It's worth checking the list in the documentation pump protection along with thresholds and time delays so that the staff can consciously assess unusual situations.
Pump motors - selection of drives and Power supply
Solutions are used for higher power applications three-phase pump, in which the stability of the power supply determines the service life. When fluctuations occur, the controller monitors supply voltage, alerts about extreme states and prevents starts in unfavorable conditions. A well-prepared system provides the operator opportunity to work in restricted mode, unless this poses a security risk.
Dry-running pump protection – a necessity, not an option
Lack of medium leads to a sharp increase in seal temperature and wear of the hydraulics. That's why protection of pumps against dry running are designed based on information from flow meters, pressure transmitters and probes. In the event of an incident, the logic stops the system, registers the event and - after returning to safe conditions - allows it automatic restart, if the risk of cavitation and overheating has been removed.
Level control – sensors, installation, calibration
In process tanks, the basis of safety is reliability level control. You can choose from floats, hydrostatic transducers and liquid level probes. In simple applications, simple works well float control, and where precision and resistance to interference are important - multi-state level probe and redundancy with additional level sensors.
Water level control – start/stop logic without oscillation
Stable control starts with reliable measurement. Water level control provides MIN/MAX signals, a pumped level control the medium takes into account hysteresis and delays against "flapping". It is worth showing the scale and threshold values in the visualization, and describing what and when in the reports controls the operation of the pump. This makes it easier to explain why a switch or stop occurred at a given moment.
Water level and liquid level - how to avoid falling into traps
It's not just changes that occur in industrial applications water level, but also the density, temperature and conductivity of the medium. Therefore, control liquid level it should be resistant to interference and adapted to the conditions. They work best in difficult media liquid level probes with a dirt-resistant design, and in wells or retention ponds - reliable floats in the MIN/STOP/MAX configuration.
Switches and start – safe stop and start
In many systems, the duty cycle is initiated pressure switch, which is part of local security. To limit current and hydraulic surges, it is used soft starters for pumps or inverters. On the reporting side, it is worth recording the start and stop parameters, which facilitates analysis and selection of settings.
Power supply monitoring – voltage too low and voltage too high
Grid fluctuations reduce efficiency and increase winding temperatures. When it appears voltage too low or voltage too high, the controller compares the values with the threshold shutdown voltage level and decides to make a safe stop. Additionally, the current one is recorded voltage level, which makes it easier to talk to the energy supplier and assess the impact of power quality on the durability of the drive.
Reports and indicators – current operating status and event analysis
The operator panel should clearly display data about current operating status, cycle times and run counters. This makes it easy to check when it happened stopped pump and whether turning off the pump occurred as planned. Good reports shorten diagnostics and improve operational culture.
Application examples – hydrophores and power stations
They are popular in residential buildings hydrophore sets, often controlled by an inverter, with proven start/stop logic. Z systems are commonly found in water and stormwater networks deep well pumps, where long pressure lines and variability of inflow require careful selection of safeguards. In both cases, ergonomics of operation and solid documentation are important.
Selection and documentation – technical parameters, max power, checklists
Each draft card should contain key cards technical parameters (performance range, H, NPSH), equipment description, protection class and power max auxiliary systems. The set of documents is complemented by connection diagrams, I/O lists, alarm descriptions and test protocols, thanks to which the implementation and subsequent service are without surprises. All information about Dambat solutions can be found in the Downloads section or directly under the description of a given driver. There you will find instructions and a catalog card.

Controlling the level of the pumped medium – complete scenarios
In advanced applications pumped level control the medium combines level and pressure data with the operating conditions of adjacent equipment. Algorithms predict transients and counteract oscillations. The screens present simple descriptions that explain what is happening at a given moment controls the operation of the pump; thanks to this, the operator does not have to reach the controller code.
Safe shutdown, emergency modes and recovery
In non-standard situations, predictable action is important: gentle turning off the pump, notifications and confirmation of conditions before restarting. If all criteria are met, it can be admitted automatic restart, and otherwise – go to the website. That's how it's built protection and control help maintain production and safety.

Frequently asked questions (FAQ)
Why are pumps protected against dry running?
Protection of pumps against dry running protect the system against operation without medium. When the sensors detect a lack of water, it happens turning off the pump. Once safe conditions return, it is possible automatic restart, if the controller logic allows a restart.
How does pump motor protection work?
Pump motor protection includes supervision of overload, winding temperature and power supply. Motor switches, thermal relays and voltage monitoring prevent failures and extend service life pump motors.
What is the difference between control and protection in multi-pump systems?
In multi-pump systems pump motor control includes rotation schedules and reserve logic, a protection and control cooperate in a state matrix. This allows you to distribute it evenly pump motor operation and avoid downtime.
How is water and liquid level control implemented?
Water level control i liquid level is done through liquid level probes, hydrostatic transducers or float control. Pumped level control the medium takes into account hysteresis and delays, which stabilizes the process i controls the operation of the pump no oscillations.
What are the most important technical parameters in pump documentation?
Please indicate in the documentation technical parameters, such as performance, H, efficiency, protection class and power max. They are supplemented with data about supply voltage, alarm thresholds (shutdown voltage level) and description a set of pump protection devices.
How to control the quality of power supply in three-phase pumps?
W three-phase pumps is being monitored supply voltage. In case voltage too low or voltage too high the system stops the pump and reports current working status. This protects the installation and minimizes the risk of overheating pump motor operation.
