付き設定装置。 A variable resistor that connects a fixed resistor with a small resistance value to both ends of the variable resistor, and generates a setting signal within the upper and lower limit values of the variable resistor during normal operation.
An A/D converter converts the setting signal from the variable resistor into a digital signal, and the digital signal is input and compared with a reference value, and if the value of the setting signal is outside the range of the upper and lower limit values. A setting device with a disconnection detection function that includes a signal processing section that generates a disconnection signal when a disconnection occurs.
