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.

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.

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.

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.
