What should I do if the electrostatic grounding alarm does not respond?
1. Short-circuit terminals 1, 4 with wires. If the alarm is cleared, it means that the detection circuit is open. Remove the short-circuit wires and enter the second step
2. The resistance of the detection circuit is too large due to the top oil stain, wipe the top oil stain with emery cloth, if the alarm does not disappear, enter the third step
3. Due to the loosening of the top nut, which leads to poor contact, please tighten the nut. If the alarm does not disappear, go to the fourth step
4. Due to the disconnection or looseness of the plug at the end of the electrostatic grounding clamp, please reconnect the plug. If the alarm does not disappear, go to step 5.
5. Check whether the copper nose of the grounding wire and the grounding post are in poor contact and the circuit is broken. Please tighten the screw. If the alarm does not disappear, go to step 6.
6. Check whether the cable and grounding wire at the end of the electrostatic grounding clamp are disconnected. Please replace the cable in time. If the alarm does not disappear, it means that the control module is faulty. Replace the control module.
