SV2 Series Safety Shut-off Valves
European Burner Controls
European Standards (CE, EN, etc.)
Certain European burner controls do not have separate interlock circuits. The SV2 Series valves require that the ILKIN terminal
be tied to the burner management control is some manner and not simply jumpered to L1 power.
Burner controls with independently switched line and neutral voltages will not work as is with the SV2 Series valves and require
extra components plus wiring to make them work effectively with the SV2 Series valves.
As well, per European standards, the burner management control used shall have two line voltage switching elements in
series that switch power to the valve coils. If the burner control does not have two switching elements in series, the following
alternatives may be used in the European Union, per KIWA.
For systems where VPS is not used, MV1 and MV2 may be jumpered and powered together.
Option 1
Add an external safety relay to ensure that both the switched L1 and L2 (Neutral) of the burner control are used.
