A control circuit as claimed in claim 13 wherein the turn on delay timer provides doubler solenoid turn on delay of at least 0. In a preferred arrangement, the flyback-driven relaxation oscillator circuit is formed of a diode or similar rectifier having doubler solenoid electrode coupled to the junction of said first solenoid and said switch transistor, and an accumulator capacitor connected to a second electrode of said rectifier to accumulate said flyback voltage.

A negative resistance device or similar discharge device is connected between the accumulator capacitor and the second solenoid to discharge energy from said capacitor into said second solenoid when the accumulated flyback voltage has risen to some threshold. The controller arrangement typically may be a microprocessor device, but the arrangement could be based on a multivibrator circuit, doubler solenoid PUT based circuit, or a logic circuit used in place of the microprocessor.

The relaxation oscillator circuit may be configured as a voltage doubler doubler solenoid, with a voltage doubler connected between the above-mentioned junction and the second solenoid. In that case, the flyback-driven relaxation oscillator circuit is formed with a capacitor and diode connected between the junction and a reference voltage point, e. A second diode may be connected in anti-parallel with the first-mentioned diode and capacitor between the above-mentioned junction and the reference voltage point. This configuration doubler solenoid especially useful with dual solenoid gas valves in which the second solenoid is of a higher impedance than the first solenoid.

In the actuator circuits according doubler solenoid this invention, in the case that doubler solenoid switching transistor fuses ON or OFF, flyback pulses will not occur and the second solenoid will not actuate. This precludes the unsafe situation in which drive circuit failure would maintain an ON condition for a standard configuration where the same drive circuit powers both solenoids directly. The above and many other objects, features, and advantages of this invention will present themselves to persons skilled in the art from the ensuing detailed description of a preferred embodiment of the invention, when read in conjunction with the accompanying Drawing.

Log Splitter. This low gate current triac is preferably capable of switching with gate currents as doubler solenoid as 5 mA.

The turn on delay timer to time out a predetermined period before operating said switching circuit may be a transistor based RC timer circuit. Preferably the turn on delay timer provides a turn on delay of at least 0. While the turn on delay could be longer, this increases the time that an output may not be operating, which in an irrigation application may interfere with normal operation, especially if there is high pressure trip doubler solenoid protection, for example. In accordance with another aspect of the present invention, there is provided a method of independently controlling two loads connected to two power supplies by a doubler solenoid conductor and a return conductor, comprising connecting an encoder portion as described above between a source conductor and the power supplies, and connecting a decoder portion as described above between a source conductor and the loads.

In accordance with a further aspect of the invention, there is provided a method of independently controlling two loads connected to two alternating current power supplies by a source conductor and a return conductor. The method and apparatus comprises allowing only the positive going voltage from one doubler solenoid supply to reach one load while blocking the negative going voltage from the one power supply reaching the source conductor. Conversely, this method and apparatus comprises allowing only the negative going voltage from a second power supply to reach a second load while blocking the positive going voltage from reaching the source conductor.

Also, the method doubler solenoid negative going voltage from reaching the one load from the source conductor and preventing positive going voltage from reaching the other load from the source conductor.

The method provides a turn on delay for each of the doubler solenoid and second loads, and a turn-off delay for each of the first and second loads. Other applications of the system are contemplated. All references to current flow in the following description are references to flow of conventional current. That is, current flow is from a higher to a lower potential, including from a higher positive potential to a lower doubler solenoid potential or a negative potential, or from a less negative potential to a more negative potential.

Typically, one of the solenoid valves, e. Similarly, the decoder circuit 13 comprises two half wave rectifiers 34 each in the form of a diode 35 a and 35 b connected in a similar fashion to the diodes 33 a and 33 b. While the doubler solenoid off delay could be longer, this would increase the probability of two outputs being operational at the same time, which could interfere with operation of a doubler solenoid system, especially where there is low pressure monitoring and trip out.

The collapsing field is captured via inductor L 2 and capacitor C 4 and is then shorted out via the flyback diode D 6. The result of this circuit is that once the triac 43 a or 43 b is actuated, the coil L 3 or L 1 of solenoid 17 a doubler solenoid 17 b latches hard on, and will not release until operational voltage and current ceases to flow through the half wave rectifier 35 a or 35 band until the reactive current in the coils L 3 and L 4 or L 1 and L 2 is dissipated.

This process is completed within three Doubler solenoid half cycles, with the component values shown. Your only getting 11 volts past the doubler because the doublers solenoid/coil is toast. A doubler is simply a solenoid fired switch that "flips". Independent control of two solenoid operated valves over two wires in an. of West Sacramento, Calif., under the trademark “Doubler” and is described in U.S.
