10. Programming the actuator
10.1.
KIMO 202 programming
Closing stroke-end
The closing stroke-end is automatic and non-settable. The position at which the actuator
stops is determined by the power absorbed by the actuator when the window reaches
complete closure and the seals are completely compressed, i.e., the actuator stops when
the power absorbed exceeds a preset threshold.
After each closure or intervention of the electronic protection, the chain moves in the
opposite direction for about 1 mm, in order to produce the right compression on the seals
and relax the internal mechanical parts. During operation, the KIMO202 actuators
automatically recognize and memorize the distance between window sash and frame when
the window is completely closed. The difference in the position of the protruding part of the
window sash with respect to the frame is defined as the “overlap” and allows the actuator
to acquire its own operating parameters, storing the position and type of window frame.
This procedure, known as “
OVERLAP ACQUISITION
” (paragraph 10.3), occurs the first time the
actuator closes the window completely following a RESET operation and remains stored as
an operating parameter.
Opening stroke-end
The KIMO202 actuator is supplied with the RESET procedure already executed and a
preset maximum stroke. The overlap still needs to be "acquired" (paragraph 10.3), and a
smaller stroke selected if necessary.
IMPORTANT. If connecting an electro-lock K-LOCK a new RESET procedure must be
carried out.
When using the KIMO202 Syncro³ model, the RESET procedure and acquisition of
the overlap must be performed during installation (see paragraphs 10.2 and 10.3)
before the desired opening stroke-end can be selected.
We recommend checking the electrical wiring before starting the RESET procedure. If the
settings are lost, a new RESET procedure must be performed followed by acquisition of
the overlap (see paragraphs 10.2 and 10.3).
Three
positions can be selected for the stroke-end positions of the outgoing chain by
setting dip switches no.

RESET Procedure
This procedure concerns the configuration of a single actuator, Syncro³ setting of or in
presence of a K-LOCK electromechanical lock.
This procedure should be carried out with the chain terminal (or terminals, for
configurations with several devices) uncoupled from the window sash bracket.
IMPORTANT: The dip-switch settings should be changed to non-powered
actuators; after each change it is necessary to wait a few seconds (~ 5 sec) before
restoring the power to the actuators in order for the change to become effective.
Set the dip-switches in the following manner:
DIP 1 OFF
–
DIP 2 OFF
. For
configurations with several devices (or with the K-LOCK electro-lock), the setting of
the dip-switches as described above should only be changed for one actuator, and
the other devices will link to it automatically.
Supply power to the actuators (either by opening or closing). The initializing phase
will then start.
The actuator will start at once (or after about 8 seconds if there is an electro-lock)
and perform a full closing manoeuvre (chain completely retracted) and then an
opening manoeuvre of about 5 cm. During this phase, ensure that there are no
obstacles to the movement of the chain and wait until the closing manoeuvre is
completed on all actuators.
When the operation is finished, each connected device gives a flashing orange
signal to indicate completion of the RESET procedure. Each device will give a
different number of flashes to indicate that the access code is received (actuator 1 →
1 flash → pause → 1 flash → pause; actuator 2 → 2 flashes → pause → 2 flashes
→ pause, etc.).
The power supply to the devices can now be switched off and the dip-switches used
to set the desired stroke on all the actuators.
Couple the chain terminal to the movable sash bracket.
Once the RESET procedure is executed, at the next complete closure the actuator will
repeat the overlap acquisition operation. If the K-LOCK electro-lock is present, refer to the
respective user and installation manual.
10.3.
Overlap acquisition
The operation that must be carried out to acquire the overlap (after the RESET procedure
has already been executed) is described below:
Assembly of the actuator(s) on the window (as per chapter 9).
Electrical connection of the actuator (as per chapter 8).
Coupling of the chain terminal(s) to the sash bracket.
Activating the window closing command.
Wait until the window is completely closed. An orange light will flash on the actuator
for 3 seconds to indicate that the overlap has been successfully acquired.
IMPORTANT: If, for any reason, the actuator fails to complete the closure of the
window correctly, stopping before finishing the stroke, the RESET and overlap
acquisition operation will have to be repeated in that order, until the procedure is
completed correctly.
