That covers our overview of troubleshooting, warnings, and alarms. And for each event there will be suggestions for how to remedy the issues. To remedy this warning, make sure the supply voltage is within the specified range.įor the Alpha pump you can access the event log via the Grundfos GO app. Action is only needed if the heating system is underheating or delivering discomfort. It means that the voltage provide in the grid is too low which results in the pump not performing as expected. On the UPSe pump it is displayed with the LED flashing twice. The under voltage warning can be identified on the Alpha pump by a yellow eye light and the value E2. To remedy this alarm, consider checking the system for impurities and remove any that may be found. While on the UPSe pump it is displayed by the red LED flashing once. On the Alpha pump this is shown as a red eye light and the value E1. The pump blocked alarm will stop the pump. You will need to make sure that there is sufficient liquid in the system. If the pump fails to restart after several tries, it means the system still contains too much air. The pump will try to restart a certain number of times to detect if water has returned. If the pump runs without water, the dry run protection feature will stop the pump automatically to prevent damage. Whereas on the UPSe pump it can be identified by the red LED flashing four times. On the Alpha pump the dry run alarm can be indentified by a red eye light and the value E4 on the display. Let’s take a closer look at some specific warnings and alarms. It can communicate with Grundfos GO Remote app via built-in Bluetooth technology enabling high customization options. SCALA1 is a fully intergrated, compact self-priming, pressure booster for domestic use. Pump running but attention may be needed. Suitable for: Residential groundwater intake. The Alpha and UPSe pump displays can show a yellow or red LED light: YELLOW means warning. Alpha and UPSe pumps have been designed with intuitive troubleshooting, warning, and alarm functions to help you quickly and easily identify and overcome pump problems. A lack of heat often leads to call backs and identifying the problems can be a long process which you may not be able to invoice. When a pump problem occurs, troubleshooting can be time-consuming. It will cover specific warnings and alarms and provide you with the knowledge required to help diagnose issues. Inefficient pumps that run constantly, even when there is no water being used, or poorly installed booster pumps that are not secured to the floor, can cause vibrations and noise in the system.In this module, you will gain practical insight into how to interpret troubleshooting issues. Systems with older centrifugal pumps that use fan-cooled motors, for instance, can generate vibrations throughout the system, resulting in more noise. However, the most common reason is due to poor pump technology or poor pump control. Since noise is easily transmitted via structures and components in the water supply system, it can be difficult to identify the source of the issue. In most cases, noisy pipes indicate problems in the water supply system. Noise from water pipes or the booster pump can be annoying for you and your neighbors. Otherwise, you will not get any water coming out of the taps. You can also search Grundfos research and insights for more learning materials, articles, white papers, videos and much more content to inform your solution. In this case, you will need a pressure booster. If your water supply comes from a rooftop tank or a break tank elevated from either ground level or below ground level, the pressure might not be sufficient to supply all taps and appliances with adequate levels of water pressure. If your boosting system is supplied with water from a city water mains or shallow wells, you might experience fluctuations or even no pressure coming from the city water mains.
