Ionization cable Weishaupt 1 x 1 340 mm We2511031404-2

The product is an original signal cable designed to transmit a weak ionization current from the flame sensing electrode to the burner control unit of a Weishaupt burner. It is an important component of the safety system, confirming the presence of a flame in the combustion chamber. If your burner starts but shuts down after a few seconds in lockout mode, the cause is often a fault in this cable. Technical specifications: Parameter Value Part numbers We2511031404-2, 25110314042, 972.298.075 Manufacturer Weishaupt (Germany) Cable length 340 mm Cable type Ionization (flame monitoring) Construction Single conductor 1 x 1 Warranty 1 year Weight 100 g ⚙️ Operating principle and purpose The ionization cable connects the ionization electrode to the burner control unit. Its operating principle is based on transmitting a weak electrical current (ionization signal) that occurs between the electrode and the burner housing only when a flame is present. Receiving this signal, the control unit confirms stable combustion and maintains fuel supply. If this cable is broken or damaged, the signal does not pass, and the control unit immediately stops fuel supply, putting the burner into lockout mode. ⚠️ Signs of malfunction Replacement of the ionization cable is necessary for the following symptoms: Burner starts but shuts down after 5-10 seconds in lockout mode (blocking) — the most common sign of ionization circuit problems. Unstable burner operation — periodic flame failures and safety lockouts. Visual cable damage — cracks, melted insulation, breakage, or loose contacts in plugs. Oxidation or corrosion of contact connections — reduces the quality of the transmitted micro-signal. Ionization sensor activation when UV sensor is operating — incorrect operation due to
