Abstract
Contacts of a relay (1500) may glue together during operation. This state may be measured and a controller (1100) may issue a pulse width- modulated signal at a certain duty cycle and frequency in order to vibrate the relay contacts to make them open again. Once this is the case, the process is stopped. This process may be repeated a certain number of times, and if successfully degluing is not possible, a notification may be generated (1160). Also after a certain number of degluing cycles, a signal may be generated to indicate replacement of the relay (1500).
