10) ELECTRIC LOCKS
10.1) GENERAL DESCRIPTION
The electric lock for the ETERNA 150 automation is available in 3 models, which have different behaviour during a power failure.
10.2) POSITIONING AND ELECTRIC CONNECTION
a) FAIL SAFE “ET-EBSFSA”
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-EBSFSE”
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) BISTABLE “ET-EBSBIS”
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.
The electric locks are supplied in kit, that includes the fastening brackets and fixing
accessories.
The dimensions for securing the electric lock to the automation are specified in
Paragraph "TECHNICAL DRAWINGS".
The electric lock is fastened to the automation by 2 screws M6 x 10 on nuts M6,
which are located in the special lower slot in the transom.
The sliding trolleys must be regulated so that when the leaf is in closed position, the
electric lock level can engage the trolley 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 (black colour) with the
specific terminals. The other end of the cable has a connection that is inserted in
the connector LOCK1 on the electronic control unit of the automation ETERNA 150.
If the bistable electric lock ET‑EBSBIS 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 (red colour) and the other end must be connected to the
LOCK 2 output on the electronic control unit where the connector is located.
