Detailed Answer
Zero-position protection means the operating mechanism must be at zero (no operation) at the moment of startup, or the control logic refuses to start. When an industrial remote control powers on, it checks that all buttons are released (zero position); if a button is detected as pressed, startup is blocked and an alarm sounds, preventing false actuation at power-on. Both the LDER LD series and XINGJIA series are equipped with zero-position protection, forming a complete safety system together with the emergency stop and the key switch.
