Even if this is closed, each contact ω of the auxiliary relay (7) operates because both contacts ω and (b) are closed.
The abnormality detection signal is locked by opening the contact (71). Therefore, in the new road base, the auxiliary contact point fil ~ (4)
If it is normal, the auxiliary relay (7) will operate and its b contact (7) will operate.
1) is open. For example, the auxiliary a contact (1) of the disconnector
If the auxiliary relay (5) does not operate due to poor contact, etc.
The auxiliary contact (2) in the new road base opens and the a contact 611 of the auxiliary relay (5) opens, so the auxiliary relay (7) becomes inoperable and its b contact (71) closes to detect an abnormality. Output a signal.
