.
Connect the control unit up to 4 engines.
The connection is made through two dedicated
outputs of which connect two motors in parallel.
The first release:
3-4- supply first and second motor
5-6- Control signals first and second motor
7-8 Power third and fourth motor
9-10 Control Signals third and fourth motor
If there will be two motors they can be connected
either in parallel on the first output, both
differentiated on the first and second outputs.
When connected on different outputs, The motors
work with alternating sense of rotation so as to
create an air inlet and a contemporary extraction.
If connected in parallel, the motors work with a
sense of rotation in parallel so as to double the
instantaneous flow rate of the various cycles of
operation.
Also for the third motor it will be possible to
connect it to the preferred output depending on the
unit positioning.
