pieces for recessed mounting and 4 pieces for surface mounting)
, with an
appropriate length for the type of window frame.
Equipment and tools: tape-measure, pencil, drill/electric screwdriver, set of drill
bits for metal, insert for screwing in, electrician's scissors, screwdrivers.
10. Programming the actuator
10.1.
Opening stroke-end
The opening stroke-end of the actuator can be adjusted by selecting the dip-
switches located inside the actuator underneath the black rubber plug (T)
(see fig.
below)
, near the label that indicates the state of the dip-switches.
The setting can be made very easily by selecting the dip-switches as specified in the
table below.

The actuator is factory-set with the longest stroke (210 mm).
10.2.
Closure stroke-end
The stroke-end at closure is automatic and cannot be programmed.
The actuator stops when the charge is absorbed when the window is completely
closed and the weather stripping is completely depressed.
After each closure or intervention of electronic protection devices, the chain will
move about 1 mm in the opposite direction to give correct compression to the seals
and release the mechanical parts.

Operation with BK-LOCK electromechanical lock
The actuator can also work in combination with the BK-LOCK electromechanical
lock; this operating mode can be selected using dip-switch No.4. If the dip-switch is
set on ON without the lock being connected, the actuator will not move.
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 BK-LOCK 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 the BK-LOCK manual also)
.
Power the two machines with a voltage of 24V
(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 KIMO 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.
