。[Claims for Utility Model Registration] (1) A motor that drives a valve, a full open detector that detects when the valve is fully closed, a full open detector that detects when the valve is fully closed, and a full open detector that outputs a fully open detection signal. A protection system for an electric valve device comprising: a control unit that controls a motor to stop on the condition that the motor is output, and a control unit that controls the motor to stop on the condition that a fully closed detector outputs a fully closed detection signal. In the electric valve device, the control unit controls the motor to stop on the condition that the fully open detector outputs a fully open detection signal and the fully closed detector outputs a fully closed detection signal at the same time. protection system. (2) the full-open detector outputs a full-open detection signal;
The protection system for an electric valve device according to claim 1, further comprising an indicator that performs a warning operation on the condition that the fully closed detector outputs a fully closed output signal.
