Sometimes, the pump apparatus may include a user interface to display an error message associated with one or more operational parameters of the pump apparatus. This allows the user to look at the error message and check for the remedy instruction in the instruction manual accordingly. Moreover, the instruction manual may include contact information of a service center to either call or e-mail them with the details of the error message.
- Finding information in the instruction manual and, in a way, communicating with the service center is an extended task and may also involve a misinterpretation of the displayed error message which may further delay the resolution of the error. Further, the based on the geographical location for the installation of the pump apparatus, reachability and printed language of the instruction manual may further devalue this approach. Among all the things, the user has to store and manage the instruction manuals to readily recover and browse through a multitude of pages to locate the remedy instruction.

US 4 060 716 A suggests an automatic diagnosis of a plant for the purpose to inform an operator and to allow him to perform preventive maintenance This is to avoid the failing of a component which will often cause an unwanted break down of the plant. - Therefore, in light of the foregoing, there is a need for an improved method and system for providing an error remedy instruction associated with a pump apparatus.
- In view of the above, it is an objective of the present invention to solve or at least reduce the problems discussed above. The objective is at least partially achieved according to a pump apparatus for water management and a method of operating the pump apparatus. The pump apparatus includes an inlet, an outlet, and a pump housing defining a pressure chamber. The pressure chamber is in fluid communication with the inlet and the outlet of the pump apparatus. A user interface associated with the pump apparatus includes a display unit to display an error message associated with one or more operational parameter of the pump apparatus, and input means to receive a user input to display at least one error remedy instruction. Further, the input means allows a user to select the error remedy instruction. The error remedy instruction displayed on the display unit provides an efficient and hassle-free way for finding error remedy instruction as compared to the looking for information in a printed instruction manual or other type of printed material having a multitude of pages. In an embodiment, the user interface is disposed on the pump housing of the pump apparatus. In an alternative embodiment, the user interface is a remote device linked to the pump apparatus via a communication link.
- The pump apparatus includes a diagnostic unit operatively connected to one or more sensors, the display unit and the input means. The sensors are configured to monitor the one or more operational parameters of the pump apparatus and provide signals to the diagnostic unit. Based on the received signals, the diagnostic unit identifies a fault and executes an error mode to stop an operation of the pump apparatus. During the error mode the error message is displayed on the display unit. Further, based on the user inputs, the diagnostic unit executes an error remedy mode to display the error remedy instruction on the display unit. The user interface is pre-programed to provide most appropriate remedy instruction based on the error message and avoids any sort of misinterpretation of the fault. The error message and the error remedy instruction may be displayed in a preferred language as selected by the user during the initial set up based on geographical and/or individual preference. This also avoids any kind of misinterpretation of the error message and/or the error remedy instruction by the user. Furthermore, based on the user input the diagnostic unit may selectively execute a reset mode to exit from the error mode.
- The diagnostic unit includes a memory to set a first error status flag and a second error status flag in active states. The memory is configured to set the first error status flag and the second error status flag in the active states upon activation of the error remedy mode and the error mode, respectively. Further, when the first error status flag and the second error status flag are in the active states, the diagnostic unit continuously executes the error remedy mode and the error mode, respectively. Thus, following a maintenance operation on the pump apparatus, once the user switch ON the pump apparatus, the pump apparatus starts in the error mode or the error remedy mode. This allows the user to confirm action items performed, during the maintenance operation or in case the fault is not resolved, the user can select other instructions directed towards the resolution of the fault using the input means. The memory is configured to set the first error status flag and the second error status flag to inactive states during the execution of the reset mode. Moreover, the diagnostic unit may also execute an error signalling mode when the fault is identified to provide an audio or visual warning signal to the user during the fault.

- The error remedy instruction displayed on the
error remedy page 202 provides an efficient and hassle-free way for finding remedy instruction as compared to the looking for information in a printed instruction manual or other type of printed material. This way, the user doesn't have to manage or remember the multitude of pages in the instruction manual. Moreover, theuser interface 130 is pre-programed to provide most appropriate remedy instruction based on the selected error message on theerror page 200 and this avoids any sort of misinterpretation of the displayed error message which can otherwise delays the resolution of the error and even deteriorates or damage thepump apparatus 100. - Based on the action item pertaining to the error information displayed on the
error remedy page 202 the user may switch OFF thepump apparatus 100 and perform a maintenance operation. During the maintenance operation thepower switch 137 is kept in the OFF position and theuser interface 130 is inactive and no information is displayed on thedisplay unit 132. In an embodiment, during the maintenance operation a manufacturer's logo or product brand may be displayed on thedisplay unit 132. - Following the maintenance operation on the
pump apparatus 100, once the user switch ON thepump apparatus 100 using thepower switch 137, according to an embodiment of the present invention, thepump apparatus 100 starts in the error remedy mode and thedisplay unit 132 displays theerror remedy page 202. This allows the user to confirm the action item performed, during the maintenance operation and press thepressure pad 138b (as shown inFIG. 2B ) and executes a reset mode to exit the error remedy mode R and/or the error mode E and reset thedisplay unit 132 to display the normal mode of operation of thepump apparatus 100. Alternatively, in case the user identify the fault associated with the operational parameters of thepump apparatus 100 is not resolved, the user can select other instructions directed towards the resolution of the fault using thepressure pads - Moreover, during an initial set of the
pump apparatus 100 theuser interface 130 may allow the user to select a preferred language to display the error information and remedy instructions based on the geographical location of the installation and/or the user's individual preference. This helps the user to knowledgeably make selection and follow the other instructions displayed on thedisplay unit 132. This also avoids any kind of misinterpretation of the error information and remedy instructions by the user. -
