    • A door operation control system has a door opening for moving a door between open and closed positions. A door operator control circuit selectively operates the drive means to move the door between the open and closed positions. An obstruction detection device detects whether there is an obstruction in the path of the door between the open and closed positions and generates a signal in response thereto. The obstruction detection device is connected to the control circuit by wiring to permit operation of the door opener in the absence of a signal from the obstruction detection device and to prevent certain operations of the door opener in the presence of a signal from the obstruction detection device. An error detection circuit detects faults or errors in the wiring and generates a signal to prevent certain operations of the door operator when the faults or errors are detected. The error detection circuit prevents unsafe operation of the door opener if a wiring error has made the obstruction detection device inoperative.
    • 门操作控制系统具有用于在打开位置和关闭位置之间移动门的门开口。 门操作员控制电路选择性地操作驱动装置以在打开位置和关闭位置之间移动门。 障碍物检测装置检测在打开位置和关闭位置之间的门的路径中是否存在障碍物,并响应于此产生信号。 障碍物检测装置通过布线连接到控制电路,以在没有来自障碍物检测装置的信号的情况下允许开门器的操作,并且在存在来自障碍物检测装置的信号的情况下防止开门器的某些操作 。 错误检测电路检测到故障或错误,并且当检测到故障或错误时产生信号,以防止门操作者的某些操作。 如果接线错误导致障碍物检测装置不工作,则错误检测电路防止开门器的不安全的操作。
