摘要： A switching filter is disclosed for discriminating false control signals from actual control signals. The switching filter is particularly useful on a high impedance input, such as that of a motor controller. The filter is designed to compensate for capacitive, inductive, and/or resistive coupling between extended control lines that are run in parallel with other power lines. A low impedance is switched into the otherwise high impedance control line input for a brief instant to dissipate and phase shift false control signals to prevent the controller from interpreting the false signals as actual control signals. The filter includes a first resistor connectable to sense a presence of a possible false control signal, and a second resistor, having much lower resistance than the first resistor, connected in a path between the control line input and circuit common. A switch is provided in series with the second resistor to open and close the path between the control line input and circuit common in response to the possible false control signal. A timer is activated by a presence of a possible false control signal on the first resistor and activates the switch to provide a low shunting resistance across the control line to common for the brief period. The low shunting resistance not only dissipates the amplitude of any false signals, but also phase shifts the signals such that the controller cannot recognize multiple, successive false signals as a true control signal.
摘要翻译：公开了一种用于鉴别来自实际控制信号的假控制信号的开关滤波器。开关滤波器在诸如电动机控制器的高阻抗输入之间特别有用。滤波器设计用于补偿与其他电源线并联运行的扩展控制线之间的电容，电感和/或电阻耦合。低阻抗被切换到另外的高阻抗控制线输入以短暂瞬间消散和相移错误控制信号，以防止控制器将假信号解释为实际控制信号。滤波器包括可连接以感测可能的假控制信号的存在的第一电阻器，以及连接在控制线路输入端和电路公共端之间的路径中的电阻低于第一电阻器的第二电阻器。提供与第二电阻串联的开关，以响应于可能的假控制信号来打开和关闭控制线输入和公共电路之间的路径。通过在第一电阻器上存在可能的假控制信号来激活定时器，并激活开关以在短时间段内跨控制线提供低分流电阻以共同作用。低分流电阻不仅消耗任何假信号的幅度，而且消除信号的相移，使得控制器不能将多个连续的假信号识别为真实的控制信号。

摘要： A contactor has an armature, a pull-in coil and a holding coil. When the system is energized through a first switch such as a thermostat, the low current holding coil is energized in preparation for holding the armature pulled in after the pull-in coil is energized and the armature has finished its power stroke. A solid-state switching device and the pull-in coil are connected in series between both terminals of a power source. A control circuit causes the solid-state switching device to be conductive the instant power is supplied to the circuit through the first switch. One embodiment of the control circuit is based on logic gates. RC circuits associated with the gates keep the solid-state switching device and pull-in coil conducting long enough for the armature to pull-in. After the solid-state switching device turns on, the transistor is controlled to turn off, deenergizing the pull-in coil while the holding coil holds the armature in until the first switch opens and power input is discontinued. Another embodiment, based on a programmable timer, delivers current pulses to the pull-in coil at uniform periodicity until the armature is pulled in. After the armature is pulled in, pulse signals are shunted from the solid-state switching device so it turns off, and current pulses through the pull-in coil are discontinued, while the holding coil holds the armature in pulled-in condition until the first switch is opened.

摘要： An overload control circuit and method of operation for protecting a three-phase motor from damage due to overload includes monitors reading the load on each phase of the motor and circuitry for combining the three separate phase signals into a single combined load signal which triggers the overload circuit. The gain on the combined load signal and the overload trip delay time may be calibrated and monitored by an external meter to provide for accurate and inexpensive calibration to accommodate specific operating characteristics of the motor being monitored. The circuit provides visual readouts of the mode of operation, including: (1) operating mode; (2) overload onset; (3) shut down initiated; and (4) delay to restart.
