7. ACTUATOR SYNCHRONIZATION
Depending on the rigidity of the window, we recommend installing at least one actuator for every 1.5m of window
length.
There are 2 modes to synchronize up to a maximum of 8 devices (actuators and/or blocks) in the WIFI versions to be installed
in a single window: manual synchronization and synchronization via APP.
N.B.: to calculate the maximum total force of multiple synchronized actuators, consider the following formula:
Once several actuators have been synchronized, make sure that they are not mixed up with others and that they are
installed on the same window. Installing actuators synchronised with other actuators in the same window can cause
damage to the window.
7.1
MANUAL SYNCHRONIZATION
Through the manual configuration, it is possible to synchronize 2 or more LIWIN L35 Slim and BLOCK actuators up to a maximum
number of 8 devices to be installed in a single window (Example: No. 6 actuators + No. 2 BLOCK = 8 devices). If there is a BLOCK
device in the synchronization, read the dedicated instructions.
To manually synchronize the actuators proceed as follows:
1) Make sure all chains are out of the same length. Otherwise, align the chains by powering the actuators individually (See the
"single connection" diagram in the chapter "6. ELECTRICAL CONNECTIONS");
2) Connect the actuators according to diagram 4 "NATURAL VENTILATION" on page 16 (230 VAC) or page 17 (24 VDC) in
chapter "6. ELECTRICAL CONNECTIONS".
3) Set all actuator trimmers to position M. If the actuators were previously synchronized, ensure that they are reset (see
chapter "8
RESET PROCEDURE");
4) Ensure that there no other individual actuators are powered and with trimmer set to 'M'.
5) Only power the actuators to be synchronized. The synchronization procedure must be done with powered actuators.
N.B.: All devices (not yet synchronized) with the trimmer in M do not move if an Open/Close command is given);
6) All actuator LEDs light up;
7) Move the trimmer of one of the actuators following the sequence: M-A-C, within 5 sec ('C' stands for the desired stroke and
corresponds to one of the positions 1/2/3/4). The actuator will become a MASTER device;
8) The LEDs of the Slaves turn off while the led of the Master makes a continuous fast flash for 3 seconds;
9) After the 3-second flash, the Master begins to make a slow flash indicating the number of Slaves that have been synchronized.
Synchronization completed.
E.g.: in a group consisting of a Master and 2 Slaves the Master led flashes
10) AFTER INSTALLATION OF THE ACTUATORS, carry out a complete closing manoeuvre. After synchronization, the actuators
will only accept a complete closing command.
11) The led of the Master actuator will flash during each opening and closing manoeuvre; while the LEDs of the SLAVES will remain off.
N.B.: If the synchronization fails, the LED of the Master actuator will flash quickly to signal an error (see chapter "8
RESET PROCEDURE").
N.B.: Once the actuators are synchronised to return them to the factory condition, a reset must be carried out (see chapter "8
RESET PROCEDURE").

SYNCHRONIZATION VIA MOWIN APP
NB: the MOWIN APP is intended to be used only by professionals in the sale and installation of actuators.
To synchronize two or more actuators, download the MOWIN APP available in the Android and IOS stores for free and create a
"new synchronization" following the APP instructions:
1,5m
F
= 350 * x * 0.7

= total force; x = number of synchronized actuators)
