5 - OPERATION IN CASE OF POWER SUPPLY FAILURE
If the battery module is installed in the operator, automatic door operation is guaranteed by an emergency battery.
Depending on the programming of the automation electronic control unit, the door may operate as follows:
a) Automatically open and stay open if the program selector is not set to Night Lock.
b) The door stays closed, but it can be opened by activating any opening command (motion radars, buttons, etc.).

When the battery is exhausted or there is no emergency battery, door motion is free and wings may be opened manually if the EV-
EBFSE closing electric lock is not installed.
If the EV-EBFSE electric lock is installed and the door is closed wings cannot be moved manually. In this case, to unlock the door,
release the electric lock by turning the MANUAL RELEASE knob clockwise by about 45° - 50° (see fig. below, item 2 ); under these
conditions you can manually open the door.
