operating information
The chain actuator is used to open and close the window by means of a three
steel chain (Nekos Patent)
. The movement is achieved with
SELV
) electricity that powers a gear motor controlled by a functional el
device. Window opening can be programmed, and the device allows excursion of
the chain to strokes of 70, 125, 170 and 210 mm. For the return stroke, i.e., the
closing of the window, the stroke
automa
tically calculates the required power absorption to produce the movement of
the window, and therefore no settings are required. The actuator can also be
installed without the immediate availability of electricity for window movement; in this
case the actua
tor will simply hold the window closed after assembly. The structure of
the actuator is entirely metal and it is used for room ventilation. The coupling
between the actuator and support brackets fixed to the window frame is a quick
connect coupling that al
lows the actuator to rotate in order to adapt to the stroke of
the chain, even on windows with reduced height. The brackets are fixed to the frame
during actuator assembly with just two screws. Combined with the
product and perimeter fittings, it constitutes the security lock that keeps the window
closed tight and guarantees a high thermal K.

6. Id plate and marking data
The KIMO actuators have CE marking and comply with the Standards listed in the
Declaration of Conformity. They also come with a Declaration of Incorporation, due
to their classification by the Machinery Directive as “partly completed machines”.
Both declarations are included in the final pages of this manual.
The plate data is displayed on an adhesive label placed on the outside of the casing,
which must remain intact and visible.
The main information it displays includes: manufacturer's address, product name -
model number, technical characteristics, production date and serial number.
In the event of a complaint, please indicate the serial number (SN) displayed on the
label.
An explanation of the symbols used on the label to abbreviate the technical
characteristics is given in the table in the chapter on “TECHNICAL DATA”.

7. Electric power supply
The KIMO actuator is powered with a voltage of 24V SELV. The power supply
cable has three conductors: the first conductor RED “1” that should be connected to
the + (positive) CLOSES the window; the second conductor BLACK “2” that should be
connected to the + (positive) OPENS the window; the third conductor GREEN “3” is
the conductor used for the BK-LOCK control communication signal.
The 24V low-voltage actuators can be powered using a station with emergency
batteries or a security power supply unit with an output voltage of 24V (min. 20.4V,
max. 28,8V), that is to say, sized based on the number of actuators connected.
7.1. Selecting the cross-section of the power supply cables
It is necessary to check the cross-section of the cable, which should be calculated
based on the length of the cable itself. The table below specifies the maximum length
of the cables for connection of a motor.

1.50 mmq ~120 m
2.50 mmq ~200 m
4.00 mmq ~320 m
6.00 mmq ~480m
8. Electrical connection
The machines are equipped with a power supply cable constructed in compliance
with safety standards and restrictions on radio-frequency interference.
The power supply cable - with conductors having a cross-section of 0.5 mm² - is 2
meters long with different colored conductors, as follows
 1 – RED-coloured conductor;
 2 – BLACK-coloured conductor;
 3 – GREEN-coloured conductor:

the BK-LOCK control communication signal.
9. Instructions for assembly
These indications are for specialised technical personnel and basic work and
safety techniques are not indicated.
All preparatory, assembly and electrical connection operations must be performed
by specialised technical personnel to guarantee optimal function and service of the
actuator. Check that the following fundamental conditions have been met:
Before installing the actuator, check that the moving parts of the window on
which it is to be installed are in perfect working condition and that they
open and close properly and are well balanced (where applicable).
Actuator specifications must be sufficient for movement of the window
without encountering any obstacle. The limits indicated in the technical data
table must not be superseded (page 7) and the most appropriate stroke
should be selected. Calculations should be checked using the formula
indicated on page 5.
Attention. Check that the electrical power supply corresponds to that
indicated on the TECHNICAL DATA label on the machine.
Ensure that the actuator has not been damaged during transport, first
visually and then by powering in both directions.
Check that the width of the inside of the window (where the actuator is to
be assembled) is over 360 mm, otherwise the actuator should not be
installed.
Check that once the actuator has been installed, chain completely in, the
window is perfectly closed. If this is not the case the actuator will not
function correctly as the window will not close correctly.

9.1. Preparation for mounting the actuator
Before beginning to mount the actuator, depending on the type of application, the
window frame must be prepared by carrying out the following operations.
9.2. Recessed mounting
For recessed mounting, the window frame must be prepared by milling and making
two holes as indicated in the diagram below. The depth of the milling must be at
least 30 mm.
Then make two Ø4.5 holes on the sash for the attachment bracket. The
measurements are specified in the diagram below.
9.3. Surface mounting on top-hung windows opening outwards or
bottom-hung windows
The actuator can also be surface mounted on top-hung windows opening outwards or
dormer windows and on bottom-hung windows, however for these specific applications
special support brackets are required for the actuator which must be supplied
separately.
The two half-brackets attaching the actuator to the sash, however, are the same
standard brackets supplied with the actuator and included in the package.
Warning. In order to prevent unpleasant mishaps with the machine and
possible safety hazards, carefully choose the length of the clamping screws
in order to avoid damaging the power supply cables during the mounting
procedure.
In order to carry out a cost-effective and precise up-to-standard work, it is best if you

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.
10.3. Operation with
The actuator can also work in combination with the
lock; this operating mode can be selected using dip
set on ON without the lock being connected, the actuator will not move.

. If, during the closing movement, the chain actuator stops
suddenly due to an overload or mechanical sticking, this state is
interpreted as a "closing

Sound diagnostics in case of anomaly
1 Beep
The lock is set in "with actuator" mode but does not receive any
commands from the actuator.
-
The lock does not move because it didn't receive the command.
-
Check the contact of wire "3" of the lock and that
actuator is on ON.
4 Beeps
The actuator (or actuators) are in error.
-
The lock is ready for the command but the connected actuators are in error.
-
Check the diagnostics of the actuators connected to the electromechanical
lock.
12. Che
cking for correct assembly

Check that the window is perfectly closed at corners and that there are no
obstacles caused by incorrect positioning during assembly.

Check that when the window frame is closed the chain terminal is at least a few
millimetres
away from the actuator body. This will ensure the window is properly
closed and seals are correctly compressed. In the event that this should not be
the case there is no guarantee that the window is closed correctly.

Check that hinges and support brackets
fixed against the window frame with screws fixed correctly into position.

Check that the window reaches the desired position according to the stroke
selected.
