... THE OPERATION OF SF RELAYS (when contacts are welded) SF relays work to maintain a normal operating state even when the contact welding occur by overloading or short-circuit currents easy to make weld detection circuits and safety circuits in the design to ensure safety even if contacts weld. Internal Contacts Weld If the internal contacts (No and 7) weld of 4a4b type, the armature becomes non-operational and the contact gaps of each of the four form “ ...

... When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction. 3. Cleaning For automatic cleaning, the boiling method is recommended. Avoid ultrasonic cleaning which subjects the relays to high frequency vibrations, which may cause the contacts to stick recommended that a fluorinated hydrocarbon or other alcoholic solvents be used. ...
