2. USE OF KATO SYNCRO
Kato Syncro chain actuator is provided with the new Nekos patented system for the
coordinated synchronization of chain movement. Electronic speed control is comple-
tely automatic and don’t need any external control unit; it is sufficient to connect
among them red and white cables already existent on feeding cable (see scheme on
page 11).
How to recognise it
To recognise on sight chain actuator Kato Syncro from other actuators of Kato series,
there are only three details:
• Label with Syncro mark attached near the one which reports actuator technical
data.
• Electrical feeding cable which is with 5 wires (3+2) for 230V a.c. version and with 4
wires (2+2) for 24V DC version.
• Dip-switch on actuator hip has four switches; normal actuator has only two and the
signalling led.
When it has to be mounted
Kato Syncro chain actuator is mounted when are necessary two attach points becau-
se window is particularly heavy or large and a single actuator doesn’t allow the per-
fect frame closure.
Please remind that force executed from a single actuator is the same as from an ana-
logue Kato actuator; so mounting two actuators the force applied on frame is double.
Frame movement occurs uniformly, synchronized and coordinated without interrup-
tions and/or speed variations of two actuators.
In case of one of the two actuators doesn’t run for any mechanical or electrical impe-
diment, the other stops too, guarantying in this way frame integrity.
3. ACCESSORIES
The KATO actuator is packed in one single carton. Each package contains:
• Actuator with 2 metres (±5%) lead, 2,5 metres for Kato Syncro.
• Standard support brackets with distancer (A).
• Bracket for vertical assembly of the actuator (B).
• Bracket for transom window (C).
• Bracket for outward opening fixture (D).
• Adhesive template for boring.
• Small parts packaging.
• Instruction manual.
4. ELECTRICITY SUPPLY
Depending on which model is used, the actuator can function on 24V= (direct current) ,
with two cables in the lead, or on 230V~ (alternating current) 50 Hz with a three cable
lead.
For the low voltage version, a feeder with an outcoming tension correspondent to the
one indicated on the technical data label attached to the device and which transforms

GB
7
GB
6
supply mains voltage (230V~ 50Hz or other) in 24V D.C.
should be used. The feeder must have class II protection,
and correct functioning is guaranteed if a feeder type
approved or suggested by the manufacturer is used.
4.1. Section choice of supply cables
In low tension supply systems, tension falls due to cur-
rent passage in conductors is a basic aspect for safety
and good appliance function. It is therefore extremely
important that the conductor section in function of cable
length is calculated correctly.
The following table indicates cable lengths for an actua-
tor connected at nominal charge.
Cables section Actuator using
24V= 230V~
4,00 mm2~ 1.000 m ~ 3.000 m
2,50 mm2 ~ 750 m ~ 2,200 m
1,50 mm2 ~ 450 m ~ 1,350 m
0,75 mm2 ~ 160 m ~ 500 m
0,50 mm2~ 130 m ~ 400 m
5. ASSEMBLY
THESE INDICATIONS ARE INTENDED FOR THE ATTENTION OF
TECHNICIANS AND SPECIALIZED PERSONNEL. BASIC JOB
AND SAFETY TECHNIQUES ARE THEREFORE NOT INCLUDED.
All preparatory operations, assembly and electrical con-
nections must be carried out by technical and specialized
personnel to guarantee best performances and good fun-
ction of the KATO chain operated actuator.
First of all, please check that the following fundamental
points have been satisfied:
• Gear motor performances must be sufficient to move
the window; any limits indicated in the technical data
table on the product cannot be exceeded
(page 13) . Any
eventual calculations may be made using the formula
on page 15 of this manual.
• Warning. Check that appliance has electrical feeding
type equal to the one provided by checking with the
data reported on the label attached to the gear motor.
The actuator with the 3 (three) cable lead functions on
230V~ (A.C.) 50/60Hz. The actuator with the 2 (two)
cable lead functions on 24V_ (D.C.) supplied either by
batteries or by means of the lead.
• Check that the actuator has not been damaged during
Fig. 1
Fig. 2
Fig. 3
Fig. 4
Fig. 5
transport, first visually and then by working it in both
directions.
• Check that the inner section of the window length
(where the actuator will be hung), is over 405 mm in
length. Anything shorter than this will not allow for
assembly of the actuator.
• Ensure that all load limits for the actuator are always
respected in accordance with the specifications listed in
the table on page 13. The actuator must be able to move
the blind without being hindered by any obstruction of
any kind; in the event of any obstruction, select a suita-
ble track run to avoid blockage.
• Check that once the actuator has been installed the
distance between the fixed part of the window frame
(where the actuator will be mounted) and the moveable
part of the window frame
(where the bracket will be
mounted)
is more than 0 mm (Fig. 1). If the distance is
not more than this figure, the actuator will not be able
to complete its function, as the window will not be able
to close properly. A wedge should be placed under the
support brackets to redress the balance.
• Transom window frames entail the risk of injury cau-
sed by accidental fall of the window. A compass limit
switch or alternative safety system suitably designed
to prevent any accidental falls should be installed.

7. LUMINOUS INDICATIONS ON LED (only for Kato)
Before activating the actuator, familiarise yourself with messages indicated by the red
led opposite the lead. This will allow you to check that the machine is functioning pro-
perly or allow you to recognize possible irregularities.
The LED is only visible when the actuator has been turned on.
Status of LED Meaning
CONSTANTLY LIT MOTOR IN USE.
OFF AND FLASHING MOTOR HAS REGULARLY REACHED A LIMIT STOP BUT IS STILL
CONNECTED TO ELECTRICITY SUPPLY.
NORMAL REGULAR BLINKING MOTOR IN ELECTRONICAL PROTECTION DUE TO EXCESSIVE CHAR-
GE
ON AND FLASHING MOTOR IS IN STRANGE POSITION - MOTOR IS NO LONGER
PROGRAMMED.
8. PROGRAMMING THE LIMIT SWITCHES
8.1. Programming Kato actuator
Limit switches at opening
4 (four) positions can be selected for the limit switch of the outgoing chain. To pro-
gram, adjust the two dip-switches at the side of the LED. Programming is simple,
immediate and can be carried out at any time by adjusting the two dip-switches as
indicated in the following table.
Limit switch at (mm): Dip-switch
1 - left 2 - right
110 OFF OFF
200 ON OFF
300 OFF ON
400 ON ON
After the limit switches have been programmed, run a few check manoeuvres. In the
event of error, programming can be repeated to give the desired track run.

6. ELECTRICAL CONNECTIONS
6.1. Connections of Kato.
The actuator comes with a 2 m long circa (±5%) lead which has been calculated in
accordance with safety rules. In the event that the distance between the actuator and
the control button should exceed this length, the cable should be extended. See table
on
page 6 for conductor section indications. For harness, please follow the following
diagrams.
After connecting the electricity supply to the control button
(bipolar with arrows if
possible)
, check that the up key function opens the window frame and the and down
key function closes it.
In the event that keys should function to the contrary, invert cable positions.
6.2. Connections of Kato Syncro.
Cable supplied together with actuator is 2,5 m (±5%) long and it is calculated in accor-
dance with safety rules.
In the event that the distances between the actuator and the control button should
exceed 2,5 metres, it would be possible to extend only conducers for electrical feeding.
See table on page 6 for conductor section indications.
WARNING. WHITE and RED cable can not be extended and have to be connected bet-
ween them on length equal or inferior than 2,5 m; an actuators distance higher than
5 metres doesn’t guarantee a good communication of synchronization signal.
Electrical connection of cables white and red has to be done with a loose connector of
proper dimensions (clamp is on equipment). Fundamental importance has a steady
connection, with a good electrical contact because passing tension is very low (5V).
IMPORTANT. CONNECTION OF TWO CABLES (WHITE AND RED) MUST BE DONE
BEFORE ANY OTHER MOVEMENT MANOEUVRE OF SYNCHRONIZED ACTUATORS,
WITH CHAINS COMPLETELY INSIDE; OTHERWISE COMMUNICATION PROBLEMS
COULD ARISE BETWEEN TWO ACTUATORS.
For harness, please follow these diagrams.

Limit switches at closure
The limit switch at closure is automatic, electronically operated and cannot be pro-
grammed. The actuator stops when the charge is absorbed when the window is com-
pletely closed and the weather stripping is completely depressed, or when the char-
ge absorbed is more than 10% of the nominal charge. In this case, at maximum char-
ge the actuator exercises a traction force of over 330N.
After each closure or intervention of the electrical protection mechanism, the chain
moves in the opposite direction for around 1 mm. This is to loosen the tension of the
mechanical parts and gives correct pressure to the weather stripping.
When the window frame is closed, check that the chain terminal is at least a couple of
millimetres away from the actuator body. This ensures proper closure for the window
and ensures all weather stripping is sealed. If the chain terminal is not positioned cor-
rectly there is no guarantee that the window will close completely.
Check that attachments and support brackets are firmly fixed to the window frame
and that all screws have been correctly tightened.
8.2. Programming Kato Syncro actuator
Limit switches at opening
4 (four) positions can be selected for the end stroke of the outgoing chain. To program,
properly adjust the two dip-switches no. 1 and no. 2.
Programming is simple, immediate and can be carried at any time by adjusting the two
dip-switches as indicated in the following table.
Limit switch at (mm): Dip-switch
no. 1 no. 2
100 OFF OFF
200 ON OFF
300 OFF ON
400 ON ON
After limit switches programming it’s advisable to run a few check manoeuvres. In the
event of error, programming can be repeated to give the desired truck run.
Limit switches at closure
(See specific chapter for KATO).
Programming for synchronized functioning
Two Kato Syncro actuators to run in a synchronized and coordinated way, have to be
programmed. Programming consists on determining actuator “MASTER” and the one
acting as “SLAVE”.
To do this it’s necessary to program dip-switches no. 3 and no. 4.
Actuator function Dip-switch
no. 3 no. 4
MASTER ON OFF
SLAVE OFF OFF
SINGLE ON ON
Programming repetition
In the event of actuators don’t run synchronized we suggest to neutralize and repeat
the programming acting in this way:
• Take the two actuators programming back to “SINGLE” function;
• Disconnect WHITE and RED wires;
• Act an outgoing movement for at least 100 mm;
• Make the chain income completely;
• Connect again WHITE and RED wires and do again the MASTER and SLAVE program-
ming.
Example of dip-switches programming for two actuators synchronized between them:
• Actuator no. 1 dip-switch no. 3 ON dip-switch no. 4 OFF
• Actuator no. 2 dip-switch no. 3 OFF dip-switch no. 4 OFF

10. CHECKING FOR CORRECT ASSEMBLY
• Check that the window has closed completely, even at the corners, and check there
are no obstacles caused by assembly in the wrong position.
• Check that when the window frame is closed, the chain terminal is at least a couple
of millimetres distant from the actuator body. This will ensure correct closure of the
window with correct pressure on the weather stripping. If the chain terminal is not
positioned as stated there is no guarantee the window will close correctly.
• Check that all attachments and support brackets are tightly fixed to the window
frame and that all screws are correctly tightened.
• Check that the window moves to the desired position in accordance with the limit
switch selected.
• Check that the gear motor support brackets are aligned and the four fixing screws
are firmly screwed into position.
