1. Before using the relay, check whether there is any damage during transportation, that is, set it at the first setting point, turn the movable system in the direction of the magnetic pole by hand, and then release it, the movable system should be turned back to the original position Until it stops.


  
2. When readjusting the relay, you must ensure that:
  
a. The axial movement of the movable system is between 0.15 and 0.25 mm;
  
b. The air gap between the moving piece and the magnetic pole should be uniform. In any action, the moving piece and the magnetic pole should not touch each other;
  
c. During the action, the movable system must not stand in the middle position;
  
d. When the pointer rotates from the first scale to the maximum scale, the loops of the hairspring must not touch each other;
  
e. When the contact is in the open position, the total air gap between the dynamic and static contacts is not less than 1.5mm;
  
f. The gap between the static contact piece and the limiting piece is 0.1 mm to 0.3 mm.
  
3. The adjustment of the minimum setting value of the magnetic latching relay is mainly to change the size of the reaction force of the hairspring. The adjustment of the maximum setting value is mainly to change the air gap between the moving piece and the magnetic pole.
