3. Use of Cloud Syncro
CLOUD SYNCRO chain actuator is provided with the patented system for the
coordinated synchronization of chain movement. Electronic speed control is completely
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 10).
3.1. How to recognise it
To recognise on sight chain actuator CLOUD SYNCRO from other actuators of CLOUD
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 – blue, black, brown +2 – white, red)
for 230V~ version and with 5 wires (3 numbered “1”, “2”, “3” + 2 – white, red) for
24V
═
version.
•
Dip-switch on actuator hip has four switches.
3.2. When it has to be mounted
CLOUD SYNCRO chain actuator is mounted when are necessary two attach points
because window is particularly heavy or large and a single actuator doesn’t allow the
perfect frame closure.
Please remind that force executed from a single actuator is 300N; so mounting two
actuators the force applied on frame is double.
Frame movement occurs uniformly, synchronized and coordinated without interruptions
and/or speed variations of two actuators.
In case of one of the two actuators doesn’t run for any mechanical or electrical
impediment, the other stops too, guarantying in this way frame integrity.
4. Accessories
CLOUD SYNCRO actuator is packed in carton boxes. Each package contains:
•
2 actuators with 2,5 metres lead.
•
Standard support brackets with distancer (A).
•
Template for boring.
•
Small parts packaging.
