FAQ Question?What is the primary function of the VPS 504 S04 in a combustion system? Answer:The VPS 504 S04 is a safety device that automatically checks the gas safety shut-off valves for leaks before burner start-up or after shutdown. This ensures that no unburned gas can escape, preventing potential explosions. Question?Can the internal fuse be replaced by the user? Answer:Yes, the label indicates “Sicherung eingebaut, auswechselbar” (Fuse installed, replaceable). The specified fuse type is T 6.3 L 250V. Always disconnect the device from power before attempting to inspect or replace the fuse. Question?What do the ‘Stoerung’ (red) and ‘Betrieb’ (yellow/green) lights indicate? Answer:The ‘Betrieb’ light (Operation) indicates that the system has power and is running its test sequence or is in standby. The ‘Stoerung’ light (Fault) will illuminate if the system detects a leak in one of the valves during the test, preventing the burner from starting and indicating a need for maintenance. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
