Siemens LDU11.523A17 110v Burner Control Box
Siemens Part Number: BPZ:LDU11.523A17
The LDU11.523A17 control box valve proving system is designed for use with shutoff valves in connection with gas burners and gas appliances. In the event of inadmissible leakage, the system prevents the burner from starting up. The LDU11.523A17 system conforms to the requirements of EN1643 covering automatic shutoff valves for use with gas burners and gas appliances to EN161.
The LDU11.523A17 is designed for automatic gas valve proving (leakage test) based on the pressure proving principle. It is for use on gas-fired combustion plant with or without vent pipe to atmosphere. In the case of plants with no vent pipe where EN standards apply, the notes given in ƒš«Connection examples without vent pipe to atmosphereƒš» must be observed.
If the pressure increases excessively during the first test phase called ƒš«Test1ƒš», or decreases excessively during the second test phase called ƒš«Test2ƒš», the LDU11.523A17 will inhibit burner startup and initiate lockout. In that case, the lockout reset button will light up to indicate the fault. Remote indication of the fault is also possible. A program indicator, which stops whenever a fault occurs, indicates which of the valves is leaking. The LDU11 can be reset either on the unit itself or via an electric remote reset facility.
