The electric lock for the ETERNA 90 automation is available in 3 models, which have different behaviour during a power failure.
a) FAIL SAFE «ET-FSA»
In the case of a power failure, of both mains power supply and emergency battery power, the
electric lock will release the leaves, which can then be moved manually.
b) FAIL SECURE «ET-FSE»
In the case of a power failure, of both mains power supply and
emergency battery power, the electric lock will keep the leaves
locked.
c) BISTABILE «ET-BIS»
In the case of a power failure, of both mains power supply and emergency battery power, the
electric lock will remain at its current position.
Therefore, the leaves are free if the electric lock was disabled, or will remain locked if the electric
lock was enabled.
Set the Jumper J10 to position "2" on the ET-LOGIC-B control unit.
10.2) POSITIONING and ELECTRIC CONNECTION
The dimensions for fastening the electric lock to the automation are specified in
Paragraph "TECHNICAL DRAWINGS".
The electric lock is fastened to the automation by 2 M6 X 10 screws on M6 nuts
in the special lower slot in the transom.
The sliding carriages must be regulated so that when the leaf is in closed
position, the electric lock piston can hook the carriage bracket and keep the
leaves locked.
The electric lock kit includes a power supply cable. This cable has two wires on
one end that are connected to the electric lock solenoid wires with the specific
terminals. The other end of the cable has a connection that is inserted in the
LOCK1 connector on the ETERNA 90 automation electronic control unit.
If the bistable electric lock is installed, there will be a second power supply
cable. One end of it must be connected to the secondary solenoid cables
(LOCK2) of the electric lock and the other end must be connected to the LOCK 2
output on the electronic control unit where the connector is located.
Electric locks are supplied in Kit, including coupling brackets and fastening
accessories.
