Trouble shooting
The product does not communicate over Modbus
• Make sure that the product is energized.
• Check the product's Modbus connection.
• Check the product's communication settings.
• Check that the product has the right and unique
Modbus address.
The product shows the incorrect/no air flow
• Make sure that the product is energized.
• Check that the motor’s set size (Vnom) corresponds with the physical size of the product, see “Use”.
• Make sure that the product is installed according to the recommended distance to disruptions, see “Installation”.
• Check that there is an air flow.
• Make sure that the product is correctly oriented in terms of air direction. The air flow must follow the instructions on the product.
• Check that the measuring tubes are mounted correctly, plus to plus (red), minus to minus (blue).
• Check that the measuring tubes are undamaged and not creased.
• Check with the help of the k-factor and pressure difference between the red and blue measuring tubes that the flow is within the product’s measurement range.
The product does not regulate the air flow
• Make sure that the product is energized.
• Check that the damper motor has not become detached from the damper cone.
• Check that the product is connected correctly.
• Check that the product is not force controlled.
The product does not regulate on the desired air flow
• Check that the settings for Vmin and Vmax correspond with the required regulation range.
• Check the electrical connection for the required function, see wiring diagrams in the document “Description of functions & wiring diagram”.
Product does not exit test mode
• Check that the product is connected correctly, check the “Y” signal and polarity on “G” and “G0”. See
“Connections”.
• Check the setpoint settings for Vmin and Vmax. The value for Vmax must be higher than Vmin in order for the product to be in automatic mode.
• If Modbus communication is used for the damper, test mode can be active via the communication. Try disconnecting the Modbus cables and set the motor in automatic mode. See “Use”.
Cleaning
Ideally, the product should be cleaned in connection with the cleaning of the rest of the ventilation system.
Cleaning of electrical components
• If needed, use a dry cloth to clean the components.
• Never use water, detergent and cleaning solvent or a vacuum cleaner.
External cleaning
• If necessary use tepid water and a well-wrung cloth.
• Never use detergent and cleaning solvent or a vacuum cleaner.
Internal cleaning
• The damper insert must be dismantled when cleaning the ventilation system.
• Cleaning equipment such as whisks and the like must not be fed through the product.
• If necessary remove dust and other particles that can be present in the product.
• Never use detergent and cleaning solvent or a vacuum cleaner.
Service/maintenance
• The product does not require any maintenance, except for any cleaning when necessary.
• In connection with a service, mandatory ventilation inspection or cleaning of the ventilation system, check that the general condition of the product appears to be good. Pay particular attention to the suspension, cables and that they sit firmly in place.
• It’s not permissible to open or repair electrical components.
• If you suspect that the product or a component is defective, please contact Swegon.
• A defective product or component must be replaced by an original spare part from Swegon.
Materials and surface treatment
• All sheet-metal parts are galvanized sheet steel (Z275).
• Internal sound-absorbing material is made of PET
(polyethylene terephthalate), fire rating: B-s1, d0.
Disposal
Waste must be handled according to local regulations.
Product warranty
The product warranty or service agreement will not be valid/will not be extended if: (1) the product is repaired, modified or changed, unless such repair, modification or change has been approved by Swegon AB; or (2) the serial number on the product has been made illegible or is missing.
