In actual applications, safety relays may be affected by environmental factors, electromagnetic interference, etc., resulting in malfunctions or failures. In order to solve these problems.
It is recommended to:
1. Check whether the appearance is damaged or burnt, and whether the terminal is firm and unoxidized.
2. Test function: whether it can stop instantly when the emergency stop button is pressed; trigger the limit switch to confirm that the power supply is cut off normally.
3. Look at the indicator light: the power light is always on and the fault light is not on.
Strengthen the maintenance and management of safety relays, and conduct regular inspections and tests. At the same time, select safety relays with good anti-interference ability, and take effective shielding measures to reduce the impact of electromagnetic interference.
