    • Control apparatus featuring a condition sensor, a first relay responsive to a signal from the condition sensor, the first relay being in a first state in the absence of a signal from the condition sensor and being switched to a second state in response to a signal from the condition sensor, a control relay adapted to be switched between first and second states, circuitry responsive to an operation request for switching the control relay from the first state to the second state after a time interval, and clamping circuitry operative in response to the detection of the first relay in its second state during the time interval to clamp the first relay in the second state and the control relay in the first state, overriding the influence of the condition sensor on the first relay.
    • 具有条件传感器的控制装置,响应于来自条件传感器的信号的第一继电器,第一继电器在不存在来自条件传感器的信号的情况下处于第一状态,并且响应于来自 条件传感器,适于在第一和第二状态之间切换的控制继电器,响应于在一段时间间隔之后将控制继电器从第一状态切换到第二状态的操作请求的电路,以及响应于检测操作的钳位电路 在第一状态下的第一状态下的第一状态的第一状态的第一状态和第一状态下的第一继电器以及第一状态的控制继电器的第一继电器的第二状态,超过第一继电器的状态传感器的影响。
