Hydrovar pump controller repair
The Hydrovar pump controller repair is part of our service offering, as these devices are frequently used in critical applications. The Hydrovar is a pump controller distributed by several companies. Its task is to regulate pump performance according to demand. To make this possible, it features an integrated frequency converter.
As this is technically a combination of a control unit and a frequency inverter, a targeted analysis of both components is required in the event of a defect. Our experience in the Inverter repair helps us to resolve even complex fault patterns efficiently.
The Hydrovar is used in water supply, irrigation, heating control, fire-extinguishing systems and pressure booster systems, amongst other applications. In the event of a fault, we carry out targeted analysis of the control and power electronics, replace worn components and perform extensive functional tests. In our article on the Industrial electronics repair you will find further information on our working methods and our quality standards.
Operating modes of the Hydrovar pump controller
Through the integrated Control and regulation the Hydrovar pump controller offers a wide range of application possibilities in various fields, such as building services, industry or water management. For this reason, it supports several operating modes which, depending on the area of application, ensure maximum efficiency and needs-based pump performance. As part of a Hydrovar pump controller repair an understanding of these operating modes is helpful in order to analyse and rectify faults in a targeted manner. We present some of the most common operating modes in the following section.
stellar operation
In positioning mode, the Hydrovar works solely as a power controller. Control is achieved via an external frequency signal or by switching between two fixed speeds. The internal control system remains inactive in this mode. This operating mode is usually used in combination with an external controller that specifies the control commands and takes over the higher-level control.
normal operation
During normal operation, the Hydrovar performs the functions of both the control element and the controller. The internal electronics enable fully automatic control of the pump performance – entirely without an additional control device. This simplifies installation and is ideal for applications where independent pressure or flow control is required.
cascade operation
In cascade operation, multiple Hydrovar pump controllers can be networked together. Depending on the system configuration, there can be one or more masters. If only one master is used, it takes over the complete control of the connected units. If there are multiple master devices, the system is designed to be fail-safe: if one master fails, another automatically takes over control. This function is particularly advantageous in systems with high availability requirements.
Fault with the Hydrovar pump controller
Hydrovar pump controllers are available in power ranges from 1.5 to 22 kilowatts. Despite different variants, the technical design is largely identical, which is why typical fault patterns are also frequently the same. Models with a display indicate faults via corresponding error codes, while devices without a display use a flash code.
Many faults can be cleared by completely disconnecting the power supply for at least 60 seconds. If the error then persists, it is referred to as a permanent fault. If, on the other hand, the error only occurs occasionally, it is a sporadic or recurring fault.
Particularly with sporadic issues, identifying the cause during a Hydrovar pump controller repair can be challenging, as the fault cannot always be reliably reproduced on the test bench. In such cases, experience, targeted analysis and, where appropriate, the use of special test methods are crucial.
fault analysis by process of elimination
If an error occurs permanently or repeatedly, the cabling and connected sensors should first be carefully checked. If no anomalies are found there, you can use the error code, or its meaning, as the basis for a repair request with us. We will be happy to assist you with further diagnosis and the repair of the affected device.
Currently known issues to us
Currently, the most common issue we are aware of is the complete failure of the Hydrovar. In this case, the device no longer responds, and both the power LED and the RUN LED remain unlit. The Hydrovar shows no function whatsoever. For further information, please feel free to contact us at 02826-88198 call or via Contact form contact.
