電源回路に自動的に切換えられて非常運転に入る。1. In the event of a power outage in the elevator regular power supply If the elevator regular power supply (U, V, W phase) is out of power, the power failure detection relay 978 in Figure 1 turns off, and the
In the figure, since the contact A-3 and A1 of the auxiliary switch AUX are closed, P-9781b-4T1a-(A
-3)-(A-1.) 1g 7UA-N circuit turns on emergency operation start relay 97TJA during power outage, and the elevator is automatically switched from the regular power supply circuit to the emergency power supply circuit by a circuit not shown. and goes into emergency operation.
