EL-FI Drainage Control Monitor from Emotron
EL-FI Drainage Control Monitor from Emotron [EL-FI DCM]
gives greater lifecycle economy for 1 or 2 submersible pumps
The DCM reduces the power consumption and the need for float switches by detecting the motor load and thus adapting the pump running time to the water flow.
A common problem with submersible pumps used to drain, e.g. construction sites, mines and quarries, is that the external water-level detectors required to start and stop pumps often fail by becoming blocked by sludge. This causes increased pump system maintenance and downtime.
The new EL-FI Drainage Control Monitor (DCM) from Emotron overcomes this problem by using the pump motor as its own load sensor to start or stop the pump.
EL-FI DCM uses an algorithm to automatically calculate appropriate pump run and pause periods to continuously adjust pump operation to suit the pit filling rate. Thus external water-level detectors are no longer needed except, e.g. a high-level detector used with a 2-pump system to prevent overflowing of a waterworks tank.
For 2-pump applications, 2 EL-FI DCM units are used to control, monitor and protect 2 submersible pumps that run alternately in, e.g. sewage treatment plants and water cleaning stations.
Saving running costs and energy
Significant operational costs are saved through several product benefits. Changing the pump cycle automatically to suit the rate of water flowing into the pit cuts energy consumption dramatically. As shorter running and longer pauses result from optimizing pumping cycles, the consequent less wear and tear on pump components means less pump maintenance and fewer spare parts. Reduced or no need for external water-level sensors decreases investment costs. And unlike water-level detectors, which often demand constant attention, EL-FI DCM units are highly reliable electronic devices that are maintenance-free and protected in a cabinet.
Easy installation and automatic
An EL-FI load monitor is simply integrated with the asynchronous motor circuit, either directly or via a current transformer. After installation and the pump starts pumping, the stop level is simply and quickly set by pressing the unique Auto Set function key. The appropriate trip level is set automatically just 3 seconds later. The operator panel allows Auto Set to be used when the pump is either immersed in water or standing in a dry pit or tank.
When the submersible pump begins to draw air because of a lack of water in the pit, EL-FI DCM detects the resulting lower motor underload and stops the pump when the preset underload limit is exceeded.
El-FI DCM presents a variety of data on its display panel, including various times and measurements, and can check a number of parameters. |
