摘要： A control system for a bathing installation which has one or more electrically powered devices. A line voltage service is connected through a GFCI to power the electrically powered devices, the GFCI adapted to interrupt the service upon detection of a ground fault. A trip circuit may induce a ground fault and trip the GFCI in response to a trip signal, thereby disabling application of electrical power to the electrically powered devices. An electronic circuit is responsive to a fault condition for generating the trip signal.

摘要： A control system for bathers includes an electronic controller which controls operation of an electric heater assembly connected in a water flow path for heating water. The heater assembly includes a heater housing and electric heater element. A solid state water temperature sensor apparatus provides electrical temperature signals to the controller indicative of water temperature at separated first and second locations on or within the heater housing. The presence of water in the heater housing is detected electronically, by turning on the heater, and monitoring the temperature sensors for unusual temperature rises or other faults for a period of time thereafter. A solid state water presence sensor apparatus can also be used to determine the presence of water within the heater housing, providing electrical water presence signals to the controller indicative of the presence or absence of a body of water within the heater housing. An independent circuit apparatus is connected to the water temperature sensor apparatus and to a power relay, automatically causing high voltage power to be disconnected from the heater assembly when the water temperature exceeds a predetermined temperature. The independent circuit apparatus requiring a manual reset once the water temperature has dropped below a predetermined level to allow the high voltage power to be reconnected to the heater assembly. The system includes ground continuity detection, ground current detection and ground fault detection circuits.

摘要翻译： 用于沐浴者的控制系统包括电子控制器，其控制连接在用于加热水的水流通道中的电加热器组件的操作。 加热器组件包括加热器壳体和电加热器元件。 固态水温传感器装置向控制器提供电温度信号，其指示加热器壳体上或加热器壳体内分离的第一和第二位置处的水温。 通过打开加热器，并在此后的一段时间内监测温度传感器的异常温度上升或其他故障，可以电子地检测加热器壳体中的水。 固态水存在传感器装置还可用于确定加热器壳体内的水的存在，向控制器提供指示加热器壳体内水体存在或不存在的电水存在信号。 独立的电路装置连接到水温传感器装置和电力继电器，当水温超过预定温度时，自动使高压电力从加热器组件断开。 一旦水温下降到预定水平以下，独立电路装置需要手动复位，以允许将高压电力重新连接到加热器组件。 该系统包括接地连续性检测，接地电流检测和接地故障检测电路。
