The C–S2 stuck closed fault occurs if the common contact, C, becomes mechanically, electrically, or chemically stuck to the normally closed contact, S2. Causes of this type of fault include: Contact welding, possibly due to an inrush current or breaking current that exceeds the rating or lo...
A method for detecting a welding of a relay contact in a circuit having a DC power supply; a load circuit; a first main relay and a second main relay respectively inserted in a pair of power supply lines disposed between the DC power supply and the load circuit; and a precharge relay ...
It has to be ensured that over the entire life and even in case of malfunction (e.g. contact welding) the open contact gap will be at least 0.5 mm. If specified they also comply with the wider requirements according to EN 50205 “relays with forcibly guided contacts” ...
contact state independently of current flowing through said contacts and that does not suffer from negative common mode voltages. This may be accomplished using a signal emitter and a signal receiver to achieve relay contact welding diagnosis, such as one at each side of a contact to be ...
