General Description - Gewiss Chorus GW 90851 Manual Del Usuario

The Easy 2-channel shutter actuator 6 A – DIN rail allows you to command the movement
of 2 roller shutters (curtains, Venetian blinds, etc.) or 2 groups of roller shutters (curtains,
Venetian blinds, etc.).
Each group may have maximum 2 motors, as long as support or insulation
relays are used.
The 2 output relays for each channel, one for UP and one for DOWN movements, are
interlocked to avoid damage to the connected motor.
The movement commands can be accessed through Home Automation control or sensor
devices using the KNX bus, or they can be generated locally using the two front buttons.
The actuator is powered by the bus line and it is equipped with 2 green front LEDs for
each channel which indicate the shutter movement status (UP/DOWN).
The actuator can function in shutter or blind mode, and is capable of handling actuation following
priority, scene and alarm commands. The operating methods can be used simultaneously.
The motor actuator is able to handle movement, alarm and priority commands
simultaneously. When more than one mode is activated at the same time, the actuator
will enable the one with highest priority status.
The priority of the various functions, from maximum to minimum, is as follows:
• Relay status on loss of power to the bus
• Priority controls
• Alarms control
• Relay status on reinstatement of power to the bus
• Shutters/blinds movement, scene management,
local command push-buttons
The two green status indicator LEDs for each channel light up when the contacts with the
respective relays are closed (UP/DOWN).
SHUTTER MOVEMENT HANDLING
It raises or lowers the shutters, or stops the movement when it receives the relative
command.
If the Stop command is not sent, the motor will only stop at the end of the Movement Time:
The shutters must therefore be fitted with stroke end sensors or an autonomous clutch.
