PURPOSE:To ensure the trouble detection by displaying the trouble of an actuator when the absolute value of the difference between the detecting position and the object position of the actuator exceeds a specific amount continuously for a specific time. CONSTITUTION:The actual position of an actuator 2 detected by an actuator position sensor 1 is input to a control device 3 to control the actuator 1. At the same time, the detected actual position is also input to a trouble detecting device 4, in which the difference with the object position taken in from the control device 3 is found. When the absolute value of this difference continues for a specific time being more than a specific amount, it is decided that the actuator 2 is out of order, and a trouble display device 5 is operated to display the trouble. By such a constitution, the trouble can be surely detected. |
