Definitions

  • the invention relates to a control circuit according to the preamble of claim 1.
  • the aim of the invention is to avoid these disadvantages and a control circuit of the input to propose the type mentioned, which is largely intrinsically safe and in the case of errors in the Connection of the control circuit is ensured that it is in the event of a short to ground on Gas valve 6 does not respond to the gas valve.
  • network connections are made via connection terminals X1 1, 2 connected to an AC voltage network.
  • connection terminals X1 1, 2 connected to an AC voltage network.
  • 1, 2 switching contacts S1-1 and S1-2 arranged.
  • the mains connection 2 is connected to a normally open contact 11 of a changeover contact Relay contact 3 of a relay K3 connected.
  • the root 12 of the relay contact 3 is over a connecting line 4 connected to a plug contact connection 5, in which a gas valve 6, or whose magnetic drive is set. This drive is further in a plug contact connection 7 inserted, which is connected to the power connector 1.
  • a normally closed contact connection 13 of the relay contact 3 is connected to the Mains connection 1 connected.
  • an earth line 9 is provided which is connected to an earth line via the connection terminals X1 connected to the network and connected to an electrically conductive part to which in A dangerous touch voltage could occur in the event of a fault.
  • relay contact 3 With de-energized relay K3, relay contact 3 therefore connects root 12 to Normally closed contact connection 13, so that the gas valve 6 is short-circuited. No one can Voltage reach the gas valve 6 as long as the relay K3 is not energized and the Relay contact 3 connects the root 12 to the working contact terminal 13.
  • the network connection is 1 with the zero conductor IV of the network and the Mains connection 2 connected to a phase conductor L1.
