This is a normal function of the VIRGA III . A maintenance timer enables a brief spray of water at set intervals. By default it will activate for 15 seconds every 5 hours. This flushes the spray pipes cleans the nozzles and prevents standing water and biological growth. The interval and spray duration can be adjusted within the control panel if necessary. Water is leaking from a valve in the bottom of the spray pipe once the water spray ceases. This is a normal function of the VIRGA III. Once the water spray stops and the spray valve closes a drain valve below it will open and allow any water remaining in the pipes to drain eliminating standing water in the system. The process fluid gets hot enough to turn multiple fans on but they dont all turn on at once. There is a slight delay. This is a normal function of the VIRGA III. By default there is a 10 second delay between the controller reaching the temperature at which an action is called for and the fan turning on or off. One or more fans have stopped running. The overloads are constantly tripping. Check the settings on the motor overloads and ensure that they are not set too low. An overload should be set at the rated full load current FLC of the motor which can be found on the fan motor nameplate and on the electrical schematic supplied with the VIRGA III. If the overload is set properly and the problem persists the motor may require maintenance or repair. English 6
