Definitions

  • the invention relates to a control circuit for a gas valve with simultaneous monitoring the combustion air supply according to the preamble of claim 1, as from EP-0 698 767 B1 is known.
  • the invention is particularly based on the self-monitoring of the Flow switch for the combustion air supply directed to ensure that this in the absence of air supply does not pretend the presence of air flow by being Make contact already at the beginning of the burner cycle, i.e. before the fan is switched on, closed is.
  • the excitation current for a the is in EP 0 698 767 Gas valve switching relay supplied by a charging capacitor, which via a Normally open contact of the flow switch designed as a switch is charged.
  • the present invention simplifies the control circuit mentioned achieved by self-monitoring no longer the presence of a flow switch in the form of a switch, but the flow switch as easier Working contact can be formed, which in the presence of a predetermined Minimum flow closes. This also allows the flow switch to be used Train electronic switch, which in the presence of air flow Excitation circuit for the gas valve closes and interrupts in the absence of air flow.
  • the invention is characterized in claim 1. The fact that the supply terminal of Loading resistance when the flow switch is closed via this with the second AC supply line is connected directly or, for example, via a diode, cannot at the beginning of the burner cycle when the flow switch is incorrectly closed Charging of the charging capacitor take place because of this via the flow switch is short-circuited. This also creates an inrush current for the relay prevented.
  • Advantageous embodiments of the invention result from the subclaims.
  • the relay RY02 has a changeover contact Normally open contact NO2 and normally closed contact NC2, while the contact arm C2 on one Mains AC voltage line L is.
  • the relay RY02 is equipped with an electronic switch, e.g. a transistor Q02, connected in series, the control electrode of the output A a control electronics CE is connected.
  • a holding circuit with a diode D1 and A resistor R02 leads from the NO2 normally open contact to the excitation winding RY02 and via the electronic switch Q02 to the other mains voltage line N.
  • the Series connection of relay RY02 and electronic switch Q02 is a charging capacitor C05 connected in parallel, its charging resistor R05 via the field winding of the gas valve PV and a series resistor R01 and the normally closed contact NC2 of the relay switch with the Supply line L is connected.
  • the input E of the control electronics CE is to the assignment of the charging capacitor C05 facing away from the ground potential N, see that this control electronics CE the electronic switch Q02 by a signal on their Output A switches through as soon as the charging voltage at input E reaches a predetermined value Threshold exceeded.
  • the charging resistor R05 and the series resistor R01 are like this dimensioned that of these two resistors and the field winding of the gas valve PV flowing charging current to the capacitor C05 is not sufficient to open the gas valve PV.
  • connection point P1 of resistor R02, resistor R05, capacitor C05 and relay RY02 at input E of control electronics CE is the connection point P1 facing away from the charging resistor R05 in Figures 1 and 2 to the Connection line P2 connected between valve PV and flow switch PS.
  • a charging circuit is created for the charging capacitor C05 the line L via the relay contact C2 / NC2, the resistor R01, the valve winding PV and the charging resistor R05.
  • the negative half wave is over the Series connection of diode D11 and blower motor FA bypassed capacitor C05, because the resistance value of resistor R1 (e.g. 68 kOhm) is much higher than that Fan impedance (approximately 200 ohms).
  • the thyristor TH1 is blocked because its cathode k via the fan winding FA is practically at the same potential as its Control electrode c.
  • the flow switch PS would already be closed due to some fault Start of the burner cycle, i.e. closed before the fan FA started, the would called positive half-wave also short-circuited via the flow switch PS and the Capacitor C05 could not be charged. In this way the Functionality of the flow switch PS checked before each burner cycle.
  • the flow switch PS detects a sufficient air flow, it closes its Contact C / NO.
  • the flow switch PS detects a sufficient air flow, it closes its Contact C / NO.
  • the flow switch PS flows to the other supply line N, generates the negative half-wave via the resistor R11 on the control electrode c des Thyristor TH1 a positive control current, so that the thyristor TH1 turns on and the Current path also for the negative half wave of the AC mains voltage via the valve winding PV closes.
  • the circuit is thus in the normal operating state, in which the Fan motor FA is running and the gas valve PV is open. Motor FA and valve PV is closed by switching off the supply voltage to the Terminals L and N.
  • a gas valve PV which has a Rectifier bridge circuit D11, D12, D13, D14 is excited with direct current. This is the make contact NO2 of the relay RY02 to the one input E1 and the line N to the other input E2 of the rectifier bridge connected.
  • the valve PV and the Flow switches PS are in turn connected in series and here to the two outputs A1 and A2 of the rectifier bridge connected.
  • the capacitor C05 is charged in the same way as in the previously described embodiment, the positive Half wave flows via NC2, R01, PV, R05 and P1 to capacitor C05, while the negative Half wave on the line L via the diode D11 and the fan winding FA none Charging current arises because the resistance of resistor R1 (e.g. 68kOhm) is essential is higher than the fan impedance of about 200 ohms. This predominates, as in Embodiment according to Figure 1, the charging current from the positive half wave to the negative Charging current is considerable.
  • resistor R1 e.g. 68kOhm
  • the relay RY02 responds as soon as, as described above, the charging voltage at input E exceeds the threshold and the control electronics CE turns on the transistor Q02.
  • the control electronics CE turns on the transistor Q02.
  • the AC input voltage is then applied to the Inputs E1 and E2 of the rectifier bridge and on the fan FA.
  • the flow switch PS closes and connects it Gas valve with outputs A1 and A2 of the rectifier bridge circuit. The valve opens and the system runs in normal operation.
  • the flow switch PS is not at the exit, but at the entrance of the rectifier bridge, namely between the input E2 and the Ground line N.
  • the rectifier bridge can only supply a DC excitation current for deliver the valve PV when the flow switch PS is closed.
  • One of the rectifiers the bridge circuit is a controlled rectifier, e.g. a thyristor TH1, the Control electrode g via a resistor R11, similar to that in Figure 1, to the Supply line N (ground) is connected.
  • a positive charging current flows from line L to charge capacitor C05 R01, PV, D14 and R05 to the capacitor.
  • the thyristor TH1 is blocked because of its cathode k is practically at the same potential as its via the fan winding FA Control electrode g.
  • the negative half wave is from D11 and FA as well as PS from Capacitor kept away because the resistance of resistor R1 (e.g. 68 kOhm) is significantly higher than the impedance of the fan of approximately 200 ohms.
  • the relay RY02 switches when the charging voltage of the capacitor reaches the threshold determined by CE exceeds.
  • the flow switch PS detects a sufficient air flow, it closes its Contact C / NO.
  • diode D11, valve winding PV, the diode D14 and the flow switch PS flows to the other supply line N, generates the negative half-wave via the resistor R11 on the control electrode g des Thyristor TH1 a positive control current, so that the thyristor TH1 turns on.
