11. Actuator kit with electromechanical lock
Warning. Always comply with the correct electrical connections between the
two machines; an incorrect connection may damage the machines and
create a hazardous situation.
11.1.
Electrical connection and operating logic
In order for the two machines to work in combination with one another, the required
connection must be made by connecting the wires according to the following diagram.
In the electromechanical lock select, using dip-switch No. 1, the desired stroke and
set, using dip-
switch No. 2, the “
OPERATION WITH ACTUATOR
” mode
(see instructions in
its manual also)
.
Power the two machines with a voltage of 24V═ (DC) (wire No. 1 and No. 2), inverting
the polarity to open and close the system.
Powering wire No. 2 with +24V and wire No. 1 with -24V produces the following
effects:
the lock moves in the opening direction;
the lock arrives at stroke-end, stop;
the chain actuator begins opening, opening the movable sash;
the VARIA SLIM SMALL chain actuator reaches stroke-end.
Powering wire No. 1 with +24V and wire No. 2 with -24V produces the following
effects:
the chain actuator moves in the closing direction;
the actuator reaches stroke-end and stops with a short relax;
the lock moves in the closing direction;
the lock arrives at stroke-end.
Important note. If, during the closing movement, the chain actuator stops
suddenly due to an overload or mechanical sticking, this state is interpreted
as a "closing stroke-end" and thus the lock motor performs a closure, even if
the sash is not effectively closed.
