Dry contact ON/OFF control
1. Before proceeding make sure the main AC voltage is disconnected. Any
electrical connection should be done by a qualified electrician.
2. Connect AC mains to the LINE, NEUTRAL and GROUND terminals
respectively.
3. Connect terminals DT-ON/OFF & COMMON through a dry contact. The
dry contact might be controlled from a computer or a smart home system.
Refer to the figure above.
4. Connect output terminals AC OUT 1, AC OUT 2 to the
film.
5. Connect the AC mains ON again.
During this step please make sure the ON/OFF switch is in the OFF position,
otherwise the unit can enter into a latched up state. If something like this
happens remove the AC mains, move the switch to the OFF position and
restore the power supply to the unit.
6. When the dry contact is closed the
film changes to a transparent
state. When the dry contact is opened the
film returns to a
translucent state.
Note:
The same functionality can be achieved by connecting terminals DT-
ON/OFF & COMMON through a regular ON/OFF wall switch as shown in the
picture above.
ON/OFF
Frequency Switching
Gauzy’s
controllers have the capability to adjust the operating frequency
of the
system to adapt itself and prevent flickering effects under certain
lighting conditions. In addition to that, the lower the frequency used, the less
power is consumed by the
system.
The
system can work at the following settings:
1. LINE –
system operates at the line frequency and is synchronized to
Line frequency (50/60 HZ depending on country of use).
2. 32HZ –
system operates at a frequency of 32 Hz, and is not synchronized
to the line.
3. LINE/2 –
system operates at half the line frequency and is
synchronized to the line frequency (25/30 HZ depending on country of
use).
In order to define the operating frequency of the
system, use the switch
located on the side panel of the controller.
