摘要： The present invention is a method and apparatus for changing fuels used in a heating system without substantially recycling the heating system where a main flame burns fuel supplied to the heating system. A fuel changeover signal is received from a fuel selector. Flow of a first fuel to the heating system is regulated in response to the fuel changeover signal to achieve a low fire state in the heating system. A pilot flame is established in the heating system and flow of the first fuel is shut off. A fuel indicator signal is received from the fuel selector indicating a desired fuel. The main flame in the heating system which is burning the first fuel is extinguished. The pilot flame is monitored for stability and the main flame is re-established in the heating system burning the desired fuel in response to the fuel indicator signal.

摘要： An anti-bounce system for control of critical loads is provided. A control system contains two subsystems. The first subsystem functions for normal control of the critical loads, but has a relatively long information processing time. This long time might prevent the system from controlling the loads in a safe manner. The system has a second subsystem that has a very rapid processing time. Both of the subsystems are connected to the load by coupling means to monitor as a feedback signal the exact state of the loads. The second subsystem overrides the first, and disconnects power whenever there has been an interruption of power for a short period of time.

摘要： A purge time hold circuit is provided in a flame safeguard sequencer to in turn provide a safe start check of a burner control system. If a flame is indicated during a prepurge period, the purge time hold means will reset to a zero status and the timer will hold until the signal clears itself. If the flame signal does not clear itself within a preset time, a safety shut down will be commanded.

摘要： A burner control system has a microprocessor for testing parameters of operation and for indicating deviations from a preset range for each. The sensors monitoring the parameters provide their outputs as analog voltages to analog to digital (A/D) converters which provide the parameters in digital form. Tests using preset voltage standards increase the likelihood of A/D converter accuracy. In addition, as operating conditions for the burner change, different preset ranges are used for each sensor output when testing them so as to provide maximum confidence of proper burner operation.

摘要： The high fire and low fire switches normally operated by a damper in a fuel burner installation are verified by a switch test function. In the event that the switches are malfunctioning, the fuel burner sequence is extended to compensate, or the sequence is terminated and annunciated. The extension of the sequence is accomplished by a time sequencer alteration means that is part of a flame safeguard sequencer.

摘要： A flame safeguard sequencer incorporates an interlock checking means that verifies the proper status of the start or preignition interlocks in the burner system and the run interlocks of the burner system. In the event that an interlock opens during a period of time when it should not be open, the system can limit the operation of the sequence to a short time period (typically 30 seconds) to allow the interlock to reestablish a normal running state. If the correct state is reestablished, the system continues normal operation. If the correct state is not reestablished, the system is shut down on safety and a coded fault-hold indicator advises a serviceman of where to find the problem.

摘要： A safety circuit which connects a condition responsive circuit to a cyclic signal detecting circuit. In order to provide the cyclic signal detecting circuit with a continuous cyclic input, the condition responsive circuit and a cyclic redundancy checker is provided. The cyclic redundancy checker identifies a specific series of logic bits from the condition responsive circuit and responds favorably only to that series of logic bits. If any other series of logic bits occurs, the cyclic redundancy checker of the system ceases to function, thereby causing the cyclic signal detecting circuit to cease to function and it in turn opens a series contact to deenergize a critical load in a control system.

摘要： A flame safeguard control system using a microcomputer is disclosed. The microcomputer responds to the flame signal as provided from a normal flame amplification chain and an analog-to-digital converter. A safety backup circuit in the form of a redundant flame signal detection circuit analyzes the analog signal being provided to the analog-to-digital converter. In the event that the microcomputer is unable to shut the main fuel valve off, the redundant flame detection circuit becomes operative to deenergize part of a series circuit including the relay for the main fuel valve.

摘要： An annunciator for the status of interlock switches connected into a series circuit for supplying power from a power source to a load, includes a memory recording the status of each switch at a selectable instant. A plurality of display elements are arranged in a pattern corresponding to the pattern of the interlock switch circuit. A manually operable switch allows a user to select for graphically showing with the display either the switch status recorded by the memory or the current status of the switches. The signals controlling the display are conditioned so that the particular display element assigned to the first out switch as recorded in the memory flashes to indicate the switch closest to the power source which was not conducting at the selectable instant.

摘要： A power controller has upstream and downstream switches in series connection to provide redundant switching for power supplied from a power source to a load. A switch operating system closes the switch closer to the load first (downstream) and then the switch closer to the source (upstream). The operating system conditions closing the downstream switch on absence of power voltage on an upstream power terminal of the downstream switch. A preferred embodiment of the operating system performs a number of real time status checks during the connection process to assure that power voltage is properly absent and present at switch terminals during the stages of the connection process. This operating system guards against supplying power to the load if either the upstream or downstream switch's pair of contacts are welded at the time the connection process starts.
