Hydronic systems end-of-line

Executing full functional tests

Extensive functional tests are critical to assure top quality products. Microplan’s EOL test benches will: - Discover all quality issues prior to product shipment, ensuring customer satisfaction - Automatically execute pre-configured End-of-Line tests with minimal operator input, skill or training - Store all test data by boiler barcode for maximum traceability and data analytics - Display explanation of each step of the test and provide instructions with illustrations or video if necessary. Because time is critical, Microplan has developed parallel execution software for maximum efficiency. At the same time this test system integrates the functions of an R&D test bench, therefore: - free tests - automatic functions (ramps and PID controls) - measurements and trends displayed on a graph - log functions - test sequence management tool.

The software is made up of two main functions:

  • Interactive use for R&D tests
  • Pre-configured tests, made according to your specifications and described in the following.


Interactive-R&D mode
The first tool of the Interactive-R&D Mode is the Synoptic panel, where the circuits of the bench are shown in an active form. In the Interactive-R&D mode the Synoptic panel is active, which means that the operator can switch ON or OFF pumps, valves, contacts, selectors, simply clicking on their symbol. He also can gradually open or close proportional valves, or increase/decrease the frequency of inverters, simply moving sliding cursors.
Finally, he can activate, for every proportional output channel, a PID closed loop control, setting a
target of pressure, flow rate etc., and some suitable parameters. The PID control works in
background, while the operator can do other actions.
An example of Synoptic panel is in the following picture.


Pre-configured tests:

  • water flow sensor test
  • pressure sensor test
  • by-pass valve test
  • three-way valve test
